a little weak in the bass, otherwise excellent

Bluetooth: The headset could be problems with the phone (Galaxy S3) couple and this is also always immediately when he was out of time.
Battery: As I just always so 2-3 hours listening to music on the day, I can not say much at runtime, because I hang him at least every second night to the computer for charging.
Sound quality: It all sounds very good, but the bass is a little weak, but that does not bother me and is quite well balanced by the synth of the mobile phone.
Comfort: Very soft and comfortable to wear pads. Of course you sweat so, when it's hot, but adheres well within limits. Am not wearing glasses, but with my sunglasses there are no problems, which fits very well even between the head and headphones.
Ease of use: The On / Off / Play / Pause button works without problems. The volume and Spultaste also.
Microphone: I have a test call with a friend made (telephone not so much) and she said that one understands me very clearly.
I want (For me positive) mention that one perceives thus still very good (at moderate volume), which I like, because I'm on the bike on the road with this thing and have noticed the road. Outside noise
In bus and train me even no evil looked at when I heard a song loud.
All in all, a definite recommendation from my side :-)
