I was quite looking forward to the promised excellent quality from these wirless but found them slightly disapointing. They are perfectely useble, and the technology is great, but the are not for people dedicated to perfect sound. I would recommed them for those not worried about quality, but who would prefer the ease of having wireless headphones, as this is the major selling point.
I would also like to add the plugging in the base for the headphones can be quite a hassle, if you need to move it for any reason.
The range is good, but in a thick walled house (like mine) it can be a problem. the reception starts to deteriorate after about 2 rooms distance and the sound of static increases.
The surround sound function makes no difference for music, but for watching films and tv, it is far more pleasing. I would say maybe consider buying the better quality headphones if you are serious about listening to music, otherwise, a perfectly acceptable product.
