I really wanted to like these Beats by Dre headphones. Beats headphones sound pretty good, look great & very comfortable. Love the controls.. Volume, on/off, & two taps changes the track. I just purchased these Beats headphones a few days ago and so far i'm keeping them. The matte black looks great, to me they ARE comfortable. Battery life seems amazing so far, pairing was seamless with my products. The build is fine, quality plastic and again the matte black look great!
Now the sound, I have wired Beats Mixr's and they are super loud, like honestly a lil to loud, the Beats Solo 3 are loud, not super loud, not that I'm looking to go deaf but there is a difference in loudness, just a bit. To me the sound quality is spot on Beats, crisp clean with yes, great bass, perfect for the type of music I listen to which varies, I'm just a lil torn on the loudness issue. I got them new at a great price and that's why I'll most likely keep them, seriously aside from a slight difference in overall loudness they are superior wireless stylish Beats By Dr. Dre headphones with crazy battery life!  I'm keeping them, these Beats by Dre headphones are worth it! I've come to the conclusion they are definitely loud enough,sound quality is great for what your getting, battery life is amazing, and yes, to me, Beats by Dre headphones are comfortable, I've worn them watching a 2 1/2 hr move and forget they were even on, the sound quality immersed me into the movie!

  • The basic concept of wireless headset

    Even now the market has occupied a large number of headphones on the market, but this does not meet the needs of the majority of users, and thus appear in the market wireless headset. On the basic concept of wireless headset Now to some elaborate, so that we better understand the wireless headset. Wireless headset refers to the infrared and radio waves for the transmission of the headset system, which is mainly composed of these two parts. Infrared headphone operating frequency range is a few KHz to several MHz working range, because the effective distance of the infrared headset is about 10 meters, so the use of infrared headphones is within a visible range of people. beats by dre wireless The operating frequency of the radio headset is UHF 450 MHz-900MHz, VHF 130MHz-200 MHz operating range, and most of the wireless headset is working in the UHF range. They can reach the transmission range of about 100 meters, more than infrared headphones advantage lies in the wireless headset can bypass the obstacles for transmission, so this is more convenient to use.

    But if there are two or more wireless headset at the same time use, may interfere with each beats by dr dre other, it is recommended not to use two or more wireless headset. However, for wireless headphones, work in the UHF than in the beats by dre on sale beats by dr dre work on the VHF by the interference to be smaller, so generally have a wireless headset in the UHF to use.

  • Talking about the Reasonable Use of Audio Processor

    With the continuous development of science and technology, radio programs from editing, production to the dissemination, transmission, are using more advanced technology and equipment, the quality of the program is also greatly improved. Even so, if the use of equipment to understand the method is not comprehensive, it will cause the broadcast quality decline. The audio processor is one of the key equipment in the broadcast transmission system, and it has a great impact on the quality of the broadcast. In the daily work of radio technical staff are most concerned about the problem: First, the launch antenna and network matching problem. Second, the three major technical indicators of radio transmitter. Third, the audio signal in the transmission process of noise and attenuation problems.

    But little attention beats earbuds to the working state of the audio processor and set the problem, this year I participated in Xinjiang Taiwan, the Central People's Broadcasting Station jointly << let candle light lit the sun tomorrow >> live on the audio and some aspects of the problem , Combined with some of my practical experience in the work, talk about their own views.

    Broadcast audio signal in the process of the existence of a large non-linear, for audio processing equipment, it not only includes the signal compression, limiting, clipping, expansion and other processing methods, but also on the audio processing equipment installed location, lead Length, as well as in the high electromagnetic field radiation environment, anti-interference ability, and so have strict requirements. In response to this situation, I will work on the audio processor, set the method, place the location, additional features to explore, in order to use a variety of effective measures to make the audio processor in the future work to play a greater role.

    1, the requirements of audio processing:

    (1) broadcast transmission with the audio processing is more complex, mainly on the human ear audible frequency range to be compressed or limited, to prevent it from being modulated at the same time, but also to ensure that the audio to obtain a better signal to noise ratio and Audio bandwidth, so that the audio signal to maintain the characteristics of the original program on the basis of its larger processing, making it a new look, with the characteristics of the sound for the audience to receive appreciation.

    (2) In the broadcast program, the loudness of the audio signal is improved by reducing the ratio (peak / flat ratio) of the "peak" to "average" in the dynamic audio. Within the allowable modulation range, adjust the relationship between the peak and the average, to avoid the audio signal processing process due to clipping and other harmful effects caused by distortion, the audio processing, so that beats by dre cheap the peak modulation in the range, Try to increase the subjective sense of loudness effect.

    2, the basic principles of audio processing:

    Audio processing equipment, mainly by reducing the dynamic range of the way to suppress noise, including the program signal compression, peak limiting and clipping, multi-band compression and frequency selectable limits and equalization. The main purpose of compression is to narrow the program dynamic range, increase the density of the sound, as far as possible to make the audio signal peak amplitude uniform. The peak limit is a form of compression and its form, but its compression ratio is high, the start and recovery times are faster, the main purpose is to protect the subsequent channel transmission does not appear overload.

    The peak clipping process is to prevent the distortion caused by the overheating of the channel processing circuit, and "cut off" the processing of the high-level crest portion exceeding the threshold value instantaneously. Peak limits and clipping can match the density and loudness of the audio program signal, dealing with the effects of harmonic distortion and intermodulation distortion and the negative impact of signal bandwidth.

    During the audio processing, the audio spectrum is divided into several frequency bands, and each band is compressed and limited separately. Ie "multi-band compression and optional limits", if set correctly and reasonably, will effectively eliminate the intermodulation of the spectral gain. For the balance of audio processing, its role is on the one hand the use of equalizer to change the overall frequency band of the audio signal in the balance of the relevant frequency, on the other hand by changing the "sensitive frequency" loudness to create a sound feature to increase the program And it can also be used as a frequency response correction in a transmission system.

    3, the rational use of audio processor method

    Broadcast program audio processing success or not, is its actual effect that the auditory effect to judge, such as broadcast broadcast effect can be accepted by the audience, this approach we think is successful, otherwise it is failed. In this regard, I audio processor from its principle, combined with the actual use of the situation, fully tap their potential advantages, more effective and reasonable to play its effectiveness, should proceed from the following three aspects:

    (1) keep the signal without distortion

    At the front of the mid-wave broadcast transmitter, the audio processor highly processed audio signal, will contain many similar square wave flat-top waveform. The waveform of the square wave is relatively high for the amplitude and phase response of the transmission path through which it passes. In principle, if the flat amplitude and the group delay are deviated in the frequency range of the main energy of the program, the flattened top of the processed audio signal is tilted, thereby increasing the peak modulation voltage, but the average level does not increase The From the peak / flat ratio, the average level of the path is reduced, and the loudness is reduced accordingly. In this regard, we have to keep the prototype of the signal waveform after processing. The first method is to use the transmission signal cable, try to choose high quality, excellent performance of the transmission cable, requiring its distribution parameters, frequency bandwidth, the use of rough diameter, low attenuation, shielding a good copper core transmission line. This is very important and very effective. In addition, in the transmission connection, try not to add any additional equipment and branch parts, such as intermediate amplifiers, distributors, etc., to reduce the signal waveform distortion, to ensure good transmission quality.

    (2) audio processing system settings

    1, the audio processor, it consists of two circuits, one is slow moving AGC, the second is the action and recovery time moderate compressor, according to the need to set each band to adjust the better time constant. We have concluded in actual use that the low frequency band time constant is set to be slower (about 200s) than the high frequency band, which has a greater effect on increasing the signal density of the program

    2, the audio processor in the basic system also adds some auxiliary components, enabled the audio processor installed in the slow motion AGC and multi-band compressor between the frequency equalization processing components to compensate for the medium wave broadcast signal typical presence of the sound Frequently bad situation. Appropriate to enhance the 600Hz-1.2KHz sound energy in the entire audio spectrum distribution, so that the sound in the hearing becomes "larger" (ear hearing the most sensitive range of 2KHz-8KHz). Can make the audience feel the sound becomes real and pleasant.

    3, we also use the audio processor called "break the distortion" device, use it to provide negative peak control, to prevent the audio signal overflow, in order to eliminate the audience beats by dre on sale most likely to hear some of the band distortion The

    (3) where the audio processor is placed in the system

    In the system on the location of the audio processor placed, but also pay attention to, in order to effectively protect the audio processor 4, the rational use of audio processor benefits

    The use of audio processors, in addition to reducing the peak level, improve the average modulation degree, increase the sideband wave power to increase the loudness of the advantages, there are the following four benefits:

    (1) It is possible to solve the problem that the program level difference is large due to recording, switching, different program contents, and the use of different recording and reproducing apparatuses, which is difficult to solve satisfactorily when manually adjusting the program level.

    for the establishment of language programs and music programs between the volume balance to create the conditions.

    can be low on the program when the weak signal to a certain amount of amplification, so that the components are not submerged by submerged. Usually the high level of the treble component in the program is low, and it is possible to obtain an appropriate lifting after processing. The high audio component not only determines the clarity of the program, but also has a complex relationship between the heart and the physiology. Raise the audience so that the loudness is also increased.

    Stereo broadcast, which covers half the radius of the monaural broadcast with the same power level. After the use of the audio processor, it is possible to make the receiving carrier field slightly lower than the required area due to the increase of the sideband wave power To the higher quality of the signal, expanding the coverage.

    According to the information: the processed music than the pre-processing music, the average power increased by 8.2dB, it is compressed with 15dB of the general limit compared to the value obtained beats headphones cheap is 5.9dB, this value is actually equal to increase the launch 4 times the power. With the audio processor to increase the coverage, compared to other ways, can save a lot of electricity, equipment investment and maintenance costs, is a very economical and feasible method. Of course, the audio processor on the program content of the appropriate amount of compression, excessive compression will damage the content of the program, affecting the artistic effect of music, will make the stereo broadcast lost its due characteristics.

    In summary, at the transmitter's program input, an excellent audio processor should be used to compress the dynamic range of the program, increase loudness, expand program coverage, and ensure excellent stereo playback. On the current level of audio processor technology, fully able to meet the requirements of high-fidelity radio, so that after processing the sound can not hear the sound processing, that is, in the absence of processing traces, still retain the original sound of high Quality, even more than the original sound more sweet, clear, sounds. The resulting peak limits the waveform so that it does not change during the transfer to the transmitter. The audio processor should be placed close to the transmitter and the distance is as short as possible. So as to avoid changes in the distribution parameters during the transmission process, causing the parasitic modulation peak, so that the waveform has been processed to limit the peak changes, resulting in audio signal waveform distortion.

  • Sound failure do not blindly fiddle, according to this method quickly find the crux!

    First, observe the inspection method

    The observation check is done immediately after disconnecting the power supply. Without the instrument, instrument, with an intuitive feeling, to mobilize the visual, hearing, smell, touch and other four kinds of sensory characteristics, to judge. Although this method of inspection is less accurate, but the speed, observation inspection method is particularly useful for power failure check.

    one look

    Observe the machine or part and its external structure. See whether the key switch, interface, indicator light loose, whether the circuit board wiring off, with or without solder, discoloration, cracks, burst and other phenomena, whether the fuse blown, ignition, smoke, deformation, Problem with eye, direct identification and judgment.

    Second, listen

    Gently flip beats by dre studio the machine or parts, swing swing, listen to whether the parts scattered or screw off the situation, whether there is a collision sound. For continuous flip with or without abnormal "creak" sound or "flap" of the fire (when power). If these phenomena occur, the failure may occur in these places.

    Three, smell

    Smell the smell with beats by dre studio the nose, find the source of the smell, the fault may be from the place where the smell.

    Four touch

    Touch the transformer housing (after power failure), do not touch the terminal, because sometimes because of charging capacitors exist, the voltage is very high, endangering security. Feeling, whether it exceeds the normal temperature, hot, can not touch. Power tube with or without hot or cold phenomenon. Adjust the tube with or without hot or cold is not hot phenomenon. If there are these phenomena, the problem may arise in these places.

    Second, the test method

    The heuristic method is for the suspected part of the circuit using comparison, substitution, segmentation, simulation and other means of testing, looking for the fault, and then excluded. The specific method is as follows:

    1, comparison

    Find a machine that is exactly the same type as the faulty machine. Use the left and right channel parts of the same machine in a professional device to measure the voltage, resistance, and current of the corresponding part, and compare it to find the fault.

    2, alternative

    Replace the suspected components with good components, or swap the left and right channel components, especially for the integrated circuit block. If the machine is returned to normal after the part has changed, it indicates that the part is defective or damaged.

    3, split

    Will be part of the circuit and other parts of the disconnected, connected to the external power supply, injection signal, to judge.

    4, simulation

    Temperature simulation, the use of hair dryer heating, or alcohol cooling, temperature performance inspection, vibration simulation is the use of fine plastic insulation sticks click on some parts, look at the circuit work conditions, you can find some solder welding phenomenon, check the fault The This method is generally carried out by skilled practitioners, otherwise, prone to increase the phenomenon of failure.

    Third, the static parameter measurement method

    Static parameters of the measurement must be held by the manufacturer of equipment maintenance manual, indicating the various components of the terminal static operating current, or voltage, the use of multimeter to measure the various parts of the circuit current, voltage or resistance value to see if the nominal value is consistent.

    1, voltage measurement

    In this measurement process to consider the multimeter resistance to the measured value of the impact. Static measurements are not the same as dynamic measurements (when adding signals), which should be noted. Measure the static voltage when the transistor beats headphones pin, resistance, capacitor voltage is consistent with the nominal value, the relative voltage of the crystal pin to determine whether the damage to the tube.

    2, resistance measurement

    Do not use the R 10K file with the ohm file 100 or 1K file of the multimeter. In the case of power failure measurement, if the charging capacitor exists, must be insulated with a screw from the cone after the full discharge. Measure the resistance in the line must be welded to one end, otherwise the measurement is not accurate.

    3, current measurement

    When using direct measurement, the ammeter into the circuit, check the current size. When indirect measurement is used, the voltage across the voltage is measured and the voltage value is removed by the resistance value.

    In addition to static parameter measurement, but also the use of dynamic inspection method, the use of signal sources and oscilloscopes, direct beats headphones injection of the signal to check the circuit. This method is direct, accurate, and is not easy to damage components, but also on the circuit and mechanical structure adjustment and proofreading.

    Fourth, dynamic inspection method

    In addition to static parameter measurement, but also the use of dynamic inspection method, the use of signal sources and oscilloscopes, direct injection of the signal to check the circuit. This method is direct, accurate, and is not easy to damage components, but also on the circuit and mechanical structure adjustment and proofreading.

  • Listen to the sound there is no noise to teach you how to prescribe the right medicine

    Why can I always hear my monitor speakers at the end of noise from the beginning of the speaker, the noise has been a long-term troubled everyone's thorny problem. The following article to solve the noise problem can play a certain help, to help you find the source of noise, and through a number of ways to eliminate it. Noise Definition There are many types of noise, and the causes are different, and performance is different. So the classification of noise is still necessary, the following several audio equipment in the common classification of noise, and a simple description of its causes and solutions. White noise is a random noise in the whole frequency, it sounds like a stretch of "hiss" sound, similar to the TV did not signal the sound of snow when playing snow. Solution White noise is usually generated by the gain device or amplifier in the device. If the beats solo volume adjustment is too high, it is easy to produce a significant noise. This time need to check the sound card, software and speaker output volume, to ensure that each link did not produce overload conditions. Highly sensitive microphones, such as capacitive wheat, can pick up the noise of the human ear in the room environment, such as air conditioning, outdoor noise, wind and so on. Do not ignore the effects of ambient noise when recording.

    Digital distortion is often issued a harsh "buzzing" sound, sounds really not like the sound of nature. In general, it will vary depending on the process used by the computer. For example, when using different software or effects, digital distortion will change. Solution Digital distortion is generally caused by some problems with the sound card, or the monitor speakers connected to the computer on the same outlet. (Such as the monitor controller power and other digital devices such as computers connected to a separate power outlet or use a quality of the power adapter. The feedback is usually due to the microphone from the loudspeaker too close, The microphone will pick up the sound of the speaker and beats by dre studio self-excited. At this time will produce harsh high-frequency howling, watching some small band performances tuning, often there will be a whistle.Computer to wear headphones instead of listening speakers to monitor, so microphone It will not pick up the speaker sound self-excited. Performance or performance without the use of headphones, you can stay away from the speaker, and adjust the microphone gain.

    These sounds can usually be divided into the following two: First, random distribution crackling, the most likely reason is the software parameter settings. Increase the cache size (Buffer Size) should be able to get. Second, there are rhythmic crackling, such as half a second crackling once, which may be damaged or driven by the sound card is not properly installed.

    Solution This type of crackling noise is often caused by the sound card's software or drive incompatibility. Such as the Buffer Size set too low, there are Bluetooth or wireless devices in the system, or software compatibility is poor. You can check the sound card on the official website of the relevant content of the software to see if their computer is not reached the sound card required lower requirements. If your speaker came out of this kind of noise, you can try to unplug the speaker beats headphones access headphones to listen to, to determine where the noise from where to come.

    Eliminate noise tips

    1, use the balance line. The balance line is more resistant to the environment, and can be used with longer fidelity when using longer cables. The balance line is a three-core line, where two twisted pairs are used to transmit the signal and are wrapped by another shielded wire.

    2, speakers and computers use different power outlets. If the speakers and computers, sound card using the same socket, and sometimes easy to produce digital distortion noise.

    3, use the power adapter. A reliable power adapter will not only eliminate some of the noise in the line, but also shield out the strong current pulse, the device plays a protective role.

    4, do not let the amplifier overload. Any device or software to open the volume is too high, will make the bottom noise to improve, even in the mix can also be heard. Any audio device that can adjust the gain, when the knob is raised to a certain extent, will make the device inside the noise with a large enough to hear. Therefore, the speaker and sound card output gain should not be too high.

    5, do not overuse compression. Compression overuse is also easy to make the bottom noise become prominent. You can make the compression threshold level higher, lower compression rate to make the noise is not obvious, and this will make your mix has a greater dynamic range. PS: mainly refers to the recording quality in general, at the end of the larger recording audio files.

    6, the exclusion method to find the equipment in question. If the speaker can hear the noise, then a device and then a device removed to check to see what the noise is generated in the end. For example, you can pull the connection from the sound card, plug in the other playback equipment to listen. If the noise at this time did not, that the problem lies in the computer or sound card. Use the exclusion method to find out where the problem is.
