A nice accessory for a nice device.
Paired mine to a VM Galaxy S2. Paired fast and easy.
Very impressed w/ the sound quality. I really didn't expect them to sound as good as they do. AWESOME!
Controls are accessible and easy to use.
So far...NO CONS... IT'S ALL GOOD!!!

Bought these for my Dad as a Christmas present. We started using them last month and they are awesome! I ended up taking them for my own use more than he could. I put them through gym splits that include sprints and weight lifting. They are comfortable, sound great (for $40 headphones) and syncing to my IPhone is as easy as flipping the power strip.

It claims 15m distance, I could say this to be true as long as there are no big barriers, I walk into different rooms in my house and have no problems, if I go upstairs to the opposite end, it can struggle to keep the sync. Overall great Bluetooth performance.

On my iPhone, I can answer calls, hang up calls, change songs and adjust volume all very easily.

Battery life has been around 6-10 hours on a full charge to full drain.

Sound quality has great highs and great mids. I listen to rock, rap, and techno and they are good enough for me. Deep low bass lacks a little but it is to be expected with a slim/inexpensive headphone. Certain bass beats sound like a basketball being dribbled and that is the only time the SQ gets my disapproval.

I'm wearing them right now! I will buy another set if I accidentally break these, but the construction is above par so I don't see that happening without abuse.

Overall:
Ultra comfortable and ultra cool. I took a chance on these after I've had two other sets of Bluetooth headphones go bad on me and I am super happy I did. The sound quality is better than my old 2 pairs (I had the Gogroove airband and a pair of Aluratek headphones).

Sound Quality:
They have adjustable headband so I found that I had to first get the size right to fit my head. I have a bit larger of a head so I had to adjust them pretty much all the way, but they rested nice and the sound went into my ears well. Good balance overall and nice quality and soundstage. I listened to Gotye Somebody That I Used to Know and a Tiesto song with a lot of bass and both times I found the music pleasurable.

Pairing:
They were really simple to pair to my iPhone and I also paired them to my computer. Both times it was fast.

Looks/Finish:
I found the piano black finish to match perfectly to my phone. The earpads are a fake type of leather, but they do not go too hot and I found them to be really comfortable whether walking on the treadmill or at my desk.
