I gave these a whirl last weekend since I’m a sucker for new hardware. Interesting product. I know people think they’re bulky but i didn’t think they were too bad especially since the standard zero/plate styles have big arms now anyway. The buttons were good and solid the weight was excellent (in other words low). The sound quality was ok although I couldn’t get the ‘speakers’ positioned correctly so i don’t think they’d stay fixed when exercising and didn’t fit my head too well.
My opinion ? A good fiirst stab at something innovative but wait for a few more generations to come through or play safe and get an ipod…
