I received the S9-HD headphone as a birthday present. I liked them very much. Unfortunately, they had a known problem where the right speaker will cut out for no reason. I replaced one pair, but the replacement did the same thing and I could not get another replacement. So I hesitated, but ultimately gave Motorola another chance and bought the S10-HD. I'm glad I did.
I do not use these with a cellphone, but only with my iMac and iPod Touch. The sound quality is very good. The base is strong and the highs are good, though sometimes there can be sound distortion. Fiddling with the equalizer settings usually takes care of this problem.
The range of the bluetooth is a VAST improvement over the S9-HD. The S9 required putting my Touch in an armband so that it would stay in range of the headset's signal. Even then, it was not perfect. I usually wore the armband on my left arm -- sometimes, when I turned my head to the left, so that the base of the S9 turned away from my Touch, the signal would drop off. The S10 does not have this problem. I don't need an armband at all. I can easily keep my Touch in my front pants pocket, where it normally sits, and the S10 virtually never loses the signal, walking, running, riding BART. It just works. Similarly, if I'm paired with my iMac, I can roam around a good deal of the house and never lose a signal, even through walls.
The S10-HD feels a bit more comfortable to wear than the S9-HD did, though it's still a bit tight. I think it's slowly breaking in as I wear it more. The only problem is that it's still a challenge wearing the headphones and my reading glasses at the same time. Sunglasses don't appear to be as bad a problem.
If this performance continues, I can highly recommend these headphones. They look good, feel OK, and sound very good. I'll wait a few months to see if the channel drop-out problem returns.
