Great product and great value, a couple of niggles short of perfect.

Summary: Great sound quality and easy to connect and work with. Have had two minor problems including the neckband getting twisted slightly out of shape (partly due to flat postage) so it's marginally uncomfortable to wear for a more than a few minutes, and the buttons seem to decide not to work sometimes (e.g. can't adjust volume, or can't switch off without toggling connection with phone).
Excerpt: 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.
Pros: Clear Signal, Connects Easily, Fits well in ear, Good Sound, Good Volume Control, Lightweight
Excerpt: 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.
Pros: Clear Signal, Comfortable, Easy To Use, Good Sound, Long Battery Life
Summary: Sound quality from the Sennheiser MM 100 headset remains consistent even when cranked up to high volumes. There's a reasonable amount of upper bass that fits in well with the warm mid-range and relatively detailed treble, making for an aural signature that's heavy and musical.
Conclusion: Helt klart nöjd med köpet. Bra ljud och hög användbarhet. Tycker att telefonsamtal också funkar bra. Bågen är något stor men det går att böja ner den så att den vilar mot nacken. Inget stort problem. Skönt att slippa sladdar som trasslar när man tränar eller gör något annat som kräver fria händer. Bra bluetooth, enheterna hittar varandra direkt och behåller kontakten utan irriterande avbrott.
