I know it's been nearly a year and a half since anyone's had anything to say about the Aviator, but to me it's a shame these cans never got any real love. I've owned these for... I think 5 years now, and while they don't get much ear time due to the HD700 being near perfect for my tastes, I still love the Aviators. I'm currently giving them a listen with the xDuoo x2, which sounds lovely listening to How To Destroy Angels FLAC. The bass is just about where I'd want it to be, with enough presence to be enjoyable and certainly noticeable, but not enough to damage the experience. For me, they're still going strong at 100% functional, no issues with the cable or the remote/mic, nor scratches I'm aware of.
I know it's one of those headphones that people will write off due to Skullcandy, but all in all, I can't think of a headphone or IEM they've done a better job with that I'm aware of. The Mix Master was interesting, being quite feature rich for a headphone, but these to me excelled in sound quality. For me, these were a gift, so no money was spent, but I believe they were going for $150 at time of purchase. I'd say Grado SR80i at $100 was a better value, but I'm not entirely convinced it's a better headphone.
Now, I think it's time to give Moby's Hotel - Ambient a try with these...
