We've seen quite a few headsets with
built-in digital audio players, and while they may be a great solution for people who work out to music, there are a
couple of problems with them. One is that, for the most part, they're not expandable. GPX has addressed that one with
the $99 GPXSportX (which was initially announced at CES),
which, in addition to 128MB of onboard memory, supports
TransFlash cards for expansion.
It also includes an FM radio, and supports MP3 and WMA. Oh, and the second problem with headset-based players? If the
headsets stink, you're stuck with them. Don't know if GPX has addressed that one; we'll just have to wait until this
ships in May to find out.
