Bought this for using at the gym. Comfortable, lightweight and great sound! Construction seems a little light and breakable, so don't toss it around and you'll be fine!

Comments about Sennheiser MM 100 Stereo Bluetooth Wireless Headset:
The sound is pretty good, however at maximum volume there is a slight distortion / break-up in to lows. That being said this headset is light, has a reasonable battery runtime and works well with my Android phone. There is enough gain for most environments without going to "eleven" anyway.

Comments about Sennheiser MM 100 Stereo Bluetooth Wireless Headset:
The MM100 was easy to setup with my iPhone4. Once setup, it fully integrates into the iPhone audio options as soon as you turn it on. On the iPhone4 with IOS 4.2, a blue button shows up on all audio applications, letting me select the MM100 from the list of output devices.Distance to iPhone is very good, with no audio dropouts if the line of site is left reasonably unblocked. I did try putting my iPhone in my backpack and it did dropout a lot (a limitation of Bluetooth more than the device itself I suspect).Audio quality is the reason I wrote the headline above. I'm picky about my audio listening experience, but I'm not an audiophile either. Audio is full sounding, with deep solid base, and clear mid-range. Honestly, it probably sits somewhere slightly less than CD quality, but much better than FM. The sound space was also very clear. I find that the "over the ears, behind the head" style headset is more comfortable for longer listening times, but they are more difficult to store safely. At [$], these aren't priced to be accessible to most people, which I find unfortunate. Build quality is solid, but they are plastic. Sit on them and they are toast. If they were priced at or below $150 I think I could feel comfortable giving them five stars. I take one star off for being over-priced.What are they missing? They don't show the battery strength. They will trill softly at you through the speakers when the power is low. No way to easily store them as they can't be folded up and put away in a case.However, even with certain compromises, the first time I heard these I knew that I would NEVER go back to wired headphones again. I'm sure that there will be a lot of development in wireless headphones over the next few years (with Airplay, etc), but for now I'm VERY happy with the performance, functionality, and comfort of these.

Comments about Sennheiser MM 100 Stereo Bluetooth Wireless Headset:
After a few weeks of usage I am very happy with the performance. I had owned a competitor's headset which were in-ear and thought I might have to accept poorer sound. Not so, sound quality is excellent and I've found the over-the-ear system more comfortable and safer since I can hear what's going on around me. My previous headset also experienced occasional dropout. No drop out at all on this set. Battery life on my old set was about 3 hours of music listening. I've only listened a total of 6 hours to date so I don't know it it will hit the 7.5 hours or not. It was twice the price of my previous headset but well worth it in my book.
