Sony Ericsson Bluetooth MW600 (headset)

Pros: Very good battery life when used for calls
Nice design
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.
