These seem to be much better than the S9 and S9 HD, still to try out the range though as have only used them inside for now, couple of things though on the PLAY description: -
1. No SRS surround sound, this was a feature of the S9 HD and does not seem to exist on the S10's
2. No pouch, this again came with the s9 and s9 HD, no sign of it with the S10
3. Charger, questionable, they come with a USB charging cable that you plug into a PC
So, now you know what you are and are not getting, oh and one last thing, you can connect a phone and an MP3 player at the same time (providing the MP3 player supports bluetooth obvously) but you cannot connect two telephones and ask for phone support unlike some of the other mono Motorola bluetooth headsets (H17 for example).
Apart from that great kit and very comfortable to wear.
