Just picked these up for 6,700 baht at Jaymart, Siam Paragon.  Quite a nice package. A few thoughts:
- Nice comfortably, haven't      felt sore ears yet.
 - Several ways to use them, with a wire, with Bluetooth adapter or with Bluetooth directly.
 - Handles Bluetooth stereo with my P990.
 - Worked with Skype over Bluetooth on my Fujitsu P1510 (but the Fujitsu does not do stereo)
 - Great range in open area, working with my P990 for at least 30 feet.
 - So far the battery life has not been a problem, and there are several charging options, on the stand, with a cable and via USB charger.
 - Nice travel case, to keep them from getting mangled.
 
Bads:
- Normal Bluetooth connecting problems, likely with the P990.
 - Earpiece swivel is not a full 90 degrees to allow them to lie flat. Still need the Sony DJ head phones for that.
 - Could have been built a bit beefier.
 - The charger plug is small, and sometimes there is no way to know if it’s in and charging.
 - No obvious battery meter.
