Summary: Like others have said the interface is basic, the case is basic, and it's about the size of the original ipod. But unlike the original ipod, it's made of weak stuff. I've been carrying my ipods in a certain pocket of my laptop bag for as long as there have been ipods.
Summary: I thought the sound quality would far exceed that of the iPod Touch based on other reviews. It sounded the same to me, so I returned it and to Amazon's credit my money was credited back to my account less than a week after putting it in the mail.
Summary: This review isn't about the HM-601 sound quality. The other techies here have provided lots of info in that regard. I bought mine from the Head-Direct booth at a recent trade show. I thought I would avoid some drama by skipping mail order/Paypal to China.
