Koss Pro DJ 100 Headphone

The Koss Pro DJ100 headphones are the cans of choice for professional DJs and music lovers alike. With stylish spun metal earcups that swivel 180 degrees, shifting between single and standard double-ear listening is easy. Transitioning from stereo to mono modes is as simple as a flick of a switch. The Pro DJ100 soft cushions create a closed seal against ambient noise while maintaining very good wearing comfort. The Koss Pro DJ100 will even fold flat for the ultimate in portability. Expect extremely tight, satisfying bass response from these lightweight and built-to-last 'lifetime warranty' headphones.

What We Think:
The Koss Pro DJ 100 are very impressive headphones and are not just built strictly for DJs either. Portable and mobile listeners plugging into iPod, iPad, laptops or MP3 players will get amazing fidelity and tight-toned musical clarity that completely belies this headphone's friendly price. In fact, we think the 'DJ' designation a bit unfortunate since this is a can that will likely please all types of listeners seeking a highly versatile, do-it-all headphone under $100. The Pro DJ100 rounded sealed-back earcups offer great isolation factor and listening privacy for your city commutes while effectively preventing headphone bleed or audio 'leakage' into the mic when recording vocals or doing studio work. The presentation has a nice uncrowded perspective with clean focus throughout all frequencies and surprisingly little bloat or excess flab in the low-end bass response. The clarity stays even-toned through the vocal midranges with a hint of smooth roll-off at the top. All in all, a rather substantial accomplishment in the world of under-$100 headphones. Now if we could just get rid of that off-putting 'DJ' nomenclature, we bet Koss would sell twice the number of Pro DJ100 to all types of music lovers!


The Koss Pro DJ100 sealed headphones look simple and are basically built without much in the way of eye candy, but they are designed to last practically forever and sound great while doing so. The overall size dimensions are fairly compact but with circumaural, nearly full-size and perfectly round earcup cushions proving excellent environmental ambient noise insulation. The built-in mono / stereo switch is handy not just for DJ and club work but also for listeners who may perhaps be a bit hard of hearing in one ear and need to have a monophonic mix for their music reproduction. With a tough extra-beefy headband assembly and durable cord contact points, we expect you'll never have to use the Koss lifetime warranty, but it sure is nice to know its there just in case.
