.. you can check the EAST shop in city center, wherein they have a Bose showroom, or you can go to any Virgin store in villagio or landmark. they sell lots of headset, just prepare enough cash though.
.. sorry for the multiple post. my internet is going crazy. i cannot edit it. to moderator, please kindly delete it. thanks.
As said above, but Virgin doesn't normally carry them. You can also buy them online and have them shipped here. In the end this was the option I went with for price and selection.
You can alsoget it in 51 EAST on Salwa road
