Pros: Very comfortable to wear for extended periods in spite of the size. I drive a semi and 10 hours is not unusual. Voice messages internal to the headset are useful: "connected to phone", "x hours talk time" and so on.
Cons: 1) The 'in call' volume is 1/2 that of previous models. 2) Ringtone volume is extremely low even at phone maximum level. 3) The actual ringtone implemented may be OK in an office or library environment but is totally useless in background noise.
Pros: Easy to Pair, Charges Quick, Incoming calls sound great
Cons: Noise Cancellation quality not as good as expected, One size fits all, which is unfortunate if you have small ears, Miic or boom I found overtime will not hold it's position and is not adjustable.
Pros: Works well for online gaming & comfort less nerdy looking than most btooths
Cons: HAS MASSIVE PROBLEMS WITH PAIRING IPHONE 4. If it does pair it drops the pair within minutes. Trying today for an hour connects but wont pair followed instructions to a "T". Checked iphone settings, plugged, unplugged, disc my connection to game. nothing
Pros: The sound is very good, also to those who listens to me in the other end. I also use glasses, but this does not really represent a problem even if the headset itself is quite bulky. Stays on, and fairly comfortably too!
Cons: To low output volume! In noisy surroundings this headset is useless!
