Query: Remarkable product

If you're looking for the next generation personal stereo, this is it. The sound quality is just superb. FM reception is quite good. I haven't used the voice recorder, so I can't comment on that. The software that accompanies the product is rock solid. Battery life seems to be about 10 hrs.I do have my gripes:* A device of this quality deserves better than ear buds.* I found the belt clip case to be very awkward. Just inserting the stereo in the case can change the settings.* The operating controls/menu system is fairly involved.But when all is said and done, this is without a doubt the most bang for audio buck I've ever encountered. If you want true, cutting-edge sound quality in a ridiculously small package, this is for you.
