But good workmanship weaknesses in sound

I have ordered this headset thanks to the positive reviews. I can connect in terms of processing and ease of use to other reviews.
I have briefly tested it with my Samsung Galaxy S3. Pairing takes a few seconds. After that I could use it.

The cushions are in my (felt) normal to small ears but not enclose the ear. However, I can imagine that some people have problems with the size of me. For comparison: My Sennheiser PC360 offers considerably more space here, also for big ears.

The sound of the headphones do not like me. I feel the bass and even normal voices to be far too dull. A previous speaker wrote it sounded "like through a wall." As bad as I do not find it, but it goes in the direction.

A quick test with Skype shows that it expected to be no match for a real headset with built in microphone in which the microphone is placed in front of the mouth. For occasional call, but it should be enough.

For battery life I can not say anything. The headset was already loaded in the delivery.

Conclusion: definitely try. Many people seem with the muffled sound to have no problem.
