Headset frequency problems are most obvious

headset frequency problems are most obvious<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 />The 837 is more feminine , thanks to SATTC technology, more than 838 to accent the more rounded , translucent. If you like to listen to classical, music and the human voice , then choose 837 better . But if you like rock and pop , or choose to 838 bar !. <br /><br />If you tap with your fingers closed headphones cheap plastic earpiece heard the shrill sound, which is mechanical resonance . You can try to attenuate this mechanical resonance , with some noise canceling headphones shell material posted on the inner wall . But beware, the acoustic resonance is usually much larger than the effects of mechanical resonance .. <br /><br />Advantage is that the housing design is very beautiful, wearable and durable, the structure is very scientific , do not use glue you can put the whole headset together. In addition to these advantages are other drawbacks . Unfortunately, if you are the original Walkman earplugs without this , it should be cheaper.. <br /><br />MDR-E838/E837: because the number and shape are relatively similar, these two brothers seemingly looks like a pair of headphones .

The tones , some differences between the two , 838 compared Tough forceful and some of the atmosphere . <br /><br />Headphone cable is generally for comfort weight, mechanical strength , flexibility, mechanical noise is not transmitted optimization . Often these lines pure sound quality is rather poor. Of course , comfort is the first , and if you do not care about comfort , it is still a great line for return .. <br /><br />But listening to Famous Blue Raincoat when I do not like the style of the HD600 . Blue Raincoat one , in the Sake Si and female to reach the highest point, and then stop when the DT880 can really feel that lingering feeling in the air around , and he sent some 600 , although there are , but it feels less than 880 ethereal ! Also this disc , fourth song for some male voice , the voice of more 600 more magnetic , but I think it is not very natural , but give me a hint : It is processed headphone sound could this argument a little bit too because even like the beautification brother Forrest Gump , but Im not used . Another example is listening to black land , the front section of male monologue, when you feel the sound with HD600 exceptionally old, 880 if an old man sitting in front of you, sigh , in hoarse to talk !.
