Pros Very good battery life when used for calls
Excellent FM Radio sensitivity
Quality Audio streaming (but NOT with the included headphones)
Cons Very Poor audio quality with included headphones
Volume "touch-bar" not responding to touch when you want it but responds when you don't want it
Holding clip brakes very easily
Not multipoint. You have to switch devises from the menu
Very poor mic
Summary Used it for 8 months.
Cannot connect with two devices at the same time. You have to switch devices from headset menu.
Holding clip broke without forcing it.
Mediocre battery life when streaming audio.
Audio play buttons can accidentally pressed with ease.
If you want quality audio, you have to buy other headphones.
During a call the other party hears you like you are talking from a tin box.
Pros Works with most 3.5mm headphones and speakers
Works with most phones/tablets with A2DP (paired up to 3 devices)
Long battery life
With OLED display
Charges through micro usb (included)
Touch sensitive volume controls
Cons Does not show song title when paired to some phones(mine was xperia mini, and it does not also). But it works on iPad/iPhone and blackberry.
Headphone included was "too short".
3.5mm port was located on right hand side, which was a bit obstruction.
Summary Song title not showing on OLED display even if I'm using a Sony ericsson phone is annoying.
Overall works like a charm specially when watching movies on iPad and the MW600 is connected to a speaker for "surround sound" experience.
