Thanks to richjacksonkc, I just learned about bluetooth clip-on devices which let you plug in your own stereo headphones while being able to use most-to-all of the features a regular stereo bluetooth headset would offer. A search of the dealextreme website yielded a few cheapies, including a knockoff of the Nokia (the original of which isn't even supposed to be too good.) The discontinued, but findable, Jabra BT3030 is the leading contender at the moment, but I don't know about compatibility with the x, if there's something better, etc. Please advise! Thanks!
