I point out this bass issue because some vendors address it by emphasizing certain bass and upper-bass frequencies to give their headphones more "kick." This helps the headphones stand out from other headphones in the store, and some people—especially those who use their headphones when exercising or for beat matching—really want that visceral impact. But such headphones often become fatiguing to listen to over time. If you're interested in accurate audio reproduction, be careful not to be wowed by emphasized bass. (The same goes for exaggerated treble detail.) The best approach is to audition a set of headphones for several hours—or, even better, several days—with a variety of music. If the headphones still sound great at the end, there's a good chance they'll satisfy you over the long run.

The Ins and Outs of a Cable
To the get best quality out of your cable, you’ll need to pay attention to three components: the conductor, the shielding, and the connector.
- Conductor: The portion of the cable the signal passes through and acts as a shield and a filter for potential sources of noise
- Connector: The portion that connects to the equipment
Analog Audio
Analog audio relies on RCA connections. The cables are grouped in stereo pairs with one connection for the left audio and one for the right.
