ive been looking at the dj hd8 i've heard good things about sennheiser do you know the ohm impedance of the "momentum 2.0? I'm trying to find something around 7.1, 5.1 dolby digital but if it impedes the audio quality, distorts it i don't want it, nothings worse the simulated sound, in my opinion. Is the momentum orthodynamic/coil/ or electorstatic? Any opinions on amp's and dacs?
The Momentums are low impedance, 18 ohms. I guess they aren't headphones for you if you insist on high impedance. The Momentums are dynamic headphones, which (I guess) means coil (AFAICT they're not orthodynamic and definitely not electrostatic). Also reading further, the mic is on the cord, so it's not really a headset. It's more for mobile use. I just looked at the top 10 on headphone.com and tagged the microphone criteria on. The only headphones left after that were the Momentums.
I think most of the headphone manufacturers have recently been trying to make decent quality headphones usable with the amps on mobile devices. That means low impedance. Though I don't think going too far above 32 ohms will do that much to the audio quality (depending on the amp of course.) I have some old cans stashed somewhere, which - if I recall correctly - are around 300 ohms, but they aren't really usable with anything I use to listen to music anymore.
I think when you enter the realm of decent headphones, the quality of the audio becomes very subjective. The Sennheisers I have are fairly flat and don't seem to color the sound too much. Some people were less impressed with them, and would prefer something smoother or boomier or yellow or whatever. I personally liked a pair of Grados a friend of mine has just fine as well.
You really should go to a store and try some headphones on and see how you like them. It's personal opinion all the way with headphones, I think, as with most things audio.
About the multichannel effects out there - I agree they will just ruin the audio. I also don't think sticking 6 drivers or more into a pair of headphones will do anything apart from making them really really difficult to get sounding any good. That said, I've never owned a pair of multichannel headphones so what do I know
.
And I wholeheartedly agree that build quality is important. A few weeks ago the headphones I used when travelling (AKG K 495 NC) decided to snap in the middle of a flight with no stress on then what-so-ever. I think every review of the cans has comments below that basically say "Nice headphones, until the headband inevitably breaks." I wish they had been there when I did my research. I've only used the things when flying and they were three weeks out of warranty. Not fun at all!
Good luck hunting!
