I believe they use the same drivers as the Zero Audio Carbon Tenore. They sound good and I think are improving with Comply's tips. They need some break-in time to sound their best. I like the wire, thick and not easily tangled, and a bit in the mic/remote. They don't sound the best, but they offer 85-90% carbon tenor for half the price and have a mic. They will blow out most $20 Revain headphones, they don't have the widest range but they sound fairly natural if a bit dark and the bass is a bit brighter. If you want the best sound quality; Get the KZ ATE (much larger headphone case, half the price), if you want more accurate sound, get the Zero Audio Carbon Tenore (same extremely small and even more comfortable design, half the price)
