They are identical, they're just OEM versions of FA-003s and HM5s.
Okay, after 24 hours I have to say that I really like these. They're quite comfortable, they use the same near-legendary ear pads as their siblings the FA-003s. Also, they come with a nice zippered case, detachable cable, 1/4" to 1/2" adapter, and a backup pair of those same awesome earpads.
Upper bass, mids, and highs up to ~8kHz are superb. Their sound signature is mostly neutral, leaning towards warm, but not nearly to the extent of FA-011s or HD650s. I'd call them a little relaxed, not dark. They also have a nice size soundstage for closed cans and isolation is quite good, inside and out. These are very good headphones for under $200, for $70 they're certifiably insane. If I'd bought FA-003s for $170 I'd be a little irritated.
If you're into EQ, bump 30Hz, 60Hz, and 8kHz up 3dB and you're in for a treat. They go from "very good" to "outstanding" and I'd put them up against anything under $300. Don't think, just buy them.
