Come on now, let's give some advice here instead of just bashing someone.
Now here's a few things to consider.
1) Active Noise Cancellation along the Beats line in my experience is exactly the pinnacle of noise cancellation... or really, particularly that good.
2) That being said, I would not use active noise cancellation if I were a DJ. ANC works by inverting noise to cancel it out (hence noise cancelling). So microphone takes sound in, in theory no noise comes out. In theory. But this system only goes so far for sound that changes constantly. It works exquisitely well for monotonous sound (take an airplane for example), at least for the QC15's, but in a club setting where there's thumping beats and changing chords? You'd be hard pressed to find a set of cans that could eliminate noise. In a club setting, the effectiveness of cancelling out bass I would imagine would be even less effective due to feeling it. tl;dr active noise cancelling for a DJ would be a futile search
Aim for something with good noise isolation, not noise cancellation. Having good isolation is much more valuable than having poor isolation and noise cancellation. I think also that DJs tend to lean towards more bass heavy phones due to the need to outcompete the thumping bass in the environment? Some prefer more bass while others prefer a more reference leaning. Thus, a lot of DJ oriented cans have heavy bass and less treble sparkle to prevent shooting out your hearing in the upper range. It's up to you what you want, and while the Beats Pro are *okay*, you're paying a fortune ($450)for *okay* sound.
Some quick recommendations:
- Ultrasone DJ1, as has already been mentioned. I've not much personal experience with these (read: none), so someone pipe in about them and give a description as to why he should buy them as opposed to just saying to buy them?
- V-Moda Crossfade LP/LP2. While much maligned on Head-Fi in terms of the whole picture, the tuning is bass heavy with less emphasis on the trebles as I mentioned before. Durable. circumaural. From the V-moda website, getting it customized to your look is $200, although buying it off of amazon and shields separately will be ~$150.
- Senn HD-25. Balanced sound, portable, supraaural, durable the classic Head-Fi portable recommendation, plus great isolation to help with DJing. $200ish.
- Audio Technica M50. The other classic Head-Fi entry level recommendation. Also very neat. There's some picture of Dr. Dre wearing the M-50's floating around. Balanced sound with a bit of a bass emphasis, mids are a bit recessed. Again, durable, circumaural, and unlike the other two I've had some experience with, rotating cups and foldable. Price floats around, but with the right seller I think sound professionals for example sells these for $110?
