Here is another option which i am using, great surround but no mic:

- Victor-JVC SU-DH1 surround adapter from Bluetin
- Sennheiser HD448 (well any quality headphones will work)

Pro's:
- Superb surround
- Great quality audio depending on headphone
- Works with any headphone
- Supports Dolby Headphone & DTS

Con's:
- Volume is great but not super loud (won't recommend going too loud anyway)
- Don't get subwoofer powered killer explosions
- No mic, so hard for multiplayer gaming
- Wired

Overall the set-up cost about RM800.

The other awesome alternative but hard to get is the Turtle Beach X41.
