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.

Recommend Product: Yes
Pros: nice mids, stereo/mono switch
Cons: coiled cord, typical closed-back muffled sound
Before we start, full disclosure: we are BIG fans of Koss, having used the Koss ESP-950's, the Porta-Pro's since the early 90's, and most recently the Ruk30 IEM's (and a few lesser quality Koss 'phones before that).
Upon first listen, they exuded that typical closed-back plastic-y, hollow sound. After many hours of burn-in, the hollowness has subsided a little, but the plastic-y "quality" is still there...and no wonder, the cups are made of plastic.
The bass won't wallop you (like say...Beats or Skullcandy), but what is there is tuneful and certainly won't overpower the rest of the audio spectrum, which is EXACTLY what were were looking for. There have been times when we wished there was a little more impact down in the nether regions, but have resisted adding any unnecessary EQ.
Up top, they lack that little bit of pizzazz (as the 6K dip would indicate) - the sizzle in hi-hat and the sparkle in female vocals - so they won't sound fatiguing during long sessions.
Once you get over the aforementioned typical closed-back sound, get a good seal and realize these are not wow-wee, zow-wee headphones, you will be rewarded with clarity in the mids that is not easily found in sub-$100 closed-backs.
Design-wise, they have a understated, but pleasant we-mean-business serious look. The coiled cord though seems a little heavy and we wonder about the strain it puts near the connector end (Koss' famous Lifetime Warranty, will be a blessing to those who may encounter such issues). And that stereo/mono switch is a real blessing for cross-referencing our sessions.
If it sounds like we have been hard on the Koss Pro DJ100's, you are wrong. We really, really like 'em, so much so that we are keeping 'em. That's not to say they are perfect (which obviously they are not), but they just fit the bill nicely, a very good sounding budget-priced, closed-back headphones.

Recommend Product: Yes
Pros: Good low bass, forward mids, Female Vocals, Lifetime Warranty, Build Quality, Design
Cons: Comfort Issues for some, Coiled cord, some need burn-in (Titanium Driver)
Why do I like these? Their sound signature for me is addicting. It's a fun sound signature and not exactly a studio monitor. It gets you into the music like a Grado SR-225is does. Unlike the 225i, it has very good bass and even good sub-bass.
It's signature to my EARS is very well balanced yet does have quite forward mids and a slight bass boost. Some say these don't have enough bass and I don't understand this. I think they have quite a large bass boost. Slightly less than an M50 to my ears. They're not bass heavy. There is no bass bleed.
There is not tons of treble and it's slightly rolled off, but this makes it much less fatiguing for me.
Do you listen to any Asian pop music, perhaps with female vocals? You NEED these. Utada Hikaru sounds amazing on these. Yes, on a DJ headphone!
I will say that some pairs need a few days of use to be at their best. Many of the other Koss headphones are the same way I hear. They should sound good out of the box, but if not, give them some time.
I've also found that for an even bigger improvement, they work with the M50 pads. This seems to give me the impression of more treble and a larger soundstage.
These are also very detailed and not too forgiving of source. Not as detailed as the KRKs, but close. The sound to me is crystal clear and especially with vocals.
Despite being "easy to drive", they don't play well with some tiny players. I've had good luck with a Sansa Clip and Ipod Touch 2G. I think they're a good match with the Headroom Micro Amp and even the Airhead. I've found there's quite a few amps out there they just don't like.
They also make a good budget gaming headphone. I played through Bioshock 2 with them and loved every minute of it.
If you're curious, I've tried long and hard to find a DJ100 killer that's cheap. The only thing that's come close is the KRK KNS-8400. Not even the Shure SRH-940 or SRH-840 can do it.
