"dj headphones"
i have to say these are realy good headphones they sound good are powerfull look good and stick to your ears blocking all the noises around you!
i have them replaced now with sennheiser hd 25s wich probably are the best dj- studio headphones but for people who like better looking headphones id say go for the pioneer hdj1000!

"Great sound quality but shoddy construction"
Like other posters have said Great sound quality but poor construction and will fall apart after a year. I had mine for roughly a year and the part where the headphone connects to the headband broke the padding on the can s was also cracking. I however loved the sound quality and I am considering buying more just because of that if they fixed the issue of the breaking with better construction of metal or stronger plastic I would buy again.

"Excellent sound, mediocre construction"
First off, I like these headphones enough to have had several pairs over the years despite their foibles. The main reason is the excellent sound. The highs are very clear but are never tinny, the low end is full and tight, never muddy, and mid range sounds including human voice and many instruments are well reproduced and have substantial body. The frequency response of these headphones is greater than that of many peoples hearing, so you can be sure the headphones will generate any sound you can pick up, that is they wont drop very hi or low frequency sounds. This frequency response coupled with a good efficiency (dB) makes for a superb listening experience; you'll be amazed at how much more of your music there is to hear. A handy small feature is that the cord is user replaceable, so no need to replace the headphones if the plug or cord is damaged.
On the downside, they are made out of rather cheap feeling plastic which seems apt to snap under tension, though the padding is comfortable, and the folding and swiveling earpieces make various listening styles easy including DJing which they are largely made for. Additionally, I have found that these are uncomfortable after an hour or two of use, because they seem to compress your ears/head, that the tension in the band piece going over your head is too stiff. The pads of the earpieces themselves are soft and accommodate most ears well though and are resistant to sweat and stain. These are slightly heavy but only due to the quality/heft of the drivers.
Overall, these are an excellent pair of headphones, and to me provide the highest quality of listening experience for my music, if not always the best comfort. I would recommend their purchase, and would suggest you buy an extended warranty through the vendor so you won't have to worry about the integrity of the plastic bits, as I had one pair brake after a couple years.


"THEY BREAK!!"
Great sound, great looking and comfortable.. but they will break. So intend to buy them once a year. Like the Sonys, the plastic piece that holds the earphone on to the headset is cheap and cracks, then eventually splits in two. It's the most strained part on the headphone because it is constantly being pressured by taking them on and off. If they just use a tougher material, like aluminum, titanium or something it would solve the problem and they would be useable for a long time. I think it's the manufacturer's way to consistently get DJs to buy them again and again. I have a broken pair in front of me and am about to do battle with Pioneer to get a replacement.

"Head Phones"
I work as a part time DJ and find the phones great. Sound excellent and durable. Most others usually break from constantly taking them off and putting them on.
