Headphone may have

headphone may have 8<br /><br />This resistor Ra resistance should be 0.1 to 1 times the resistance of the headset in order to have heard the difference. However , do not use too small Ra, or you use a lot of current amplifier signal to get enough sound pressure , may have a negative effect on sound quality . Also note that this resistance have enough cooling power .. <br /><br />Following in Tianjin with a 500 after a really bad most expensive headphones. Advantage is suitable for almost all forms of music, live reduction degree is very realistic, balanced sound elegant , professional appearance . Disadvantage is that in order to highlight some of the features , abandoning some other , can not say the sound perfectly. <br /><br />If your headphones sound dark muddy , and is driven through the power amplifier , you may consider reducing the effective output resistance. This can also be achieved by means of an adapter , but this is in parallel with a resistor Ra in each channel . Effective output resistance is the resistance and headphone jack shunt resistance R0 * Ra / R0 + Ra. <br /><br />Sennheiser HD600 headphones such as the use of a special plug on the cable connected to the headphone , and no separate plug retail . Normally you need to sacrifice a genuine cable cut plug. Like most headphones , Sennheiser headphone cable with a lot of fine copper wire twisted into one , each thin copper wires are individually insulated . <br /><br />Without regard to their economic capacity , the blind pursuit of high-end . A lot of friends also bought HD600, enough to grade it, but is plugged into the computer and the Walkman , can play a few HD600 into strength ? In fact, there are high-end headphones light enough? High-end headphones to be equipped with advanced desktop PC , penthouse , fever LP , will afford a horse saddle with affordable , high starting point , after suffering as a result. So at the beginning of limited economic strength, burn or friends , you can start with entry- headset to start, such as the first buy DT231, K66 headphones to listen to the other , and if not , then skip directly into the high-end mid-range , so the loss is relatively small , you can also appreciate the upgrading of fun.. <br /><br />Advantages are: ROLAND mixer connected to the headphone amplifier connected to a better use than the sound more evenly , clear and bright , sound is very good, can be used to get rid of the noise on the 747 . Disadvantages are: the volume a little , because the sound quality in general, only limited use in noisy listening situations . Unfortunately, there are so many people buy this foreign junk , not to say something bad , is that the price for the Chinese people do not deserve ..
