Great overall package with smaller weaknesses

Was tired of the gym always this cable problem to have. Also mountain biking or jogging met me always the cable or transferred diverse sounds from dangling or flapping.
So it needed a Bluetothkopfhörer. My first.
The Sony MDR was virtually a belly purchase. Who in my opinion but worth it.
Use it with an iPhone 5s. Coupling problems, there were none at all. Everything was immediately set up. Control simple and easy to understand. The headphones but has no superior sound is quite satisfactory (also good bass). For this headphone is also relatively cheap. Price performance absolutely provided. Battery lasts at full volume loose two training sessions over two days by (approximately six hours).
Making calls is simple and works well. The intelligibility very good. The other party has partly the problem that it is very noisy. However, this is a "problem" which in reality is an advantage (to understand better than nothing at all).
Since I'm wearing glasses, I was afraid that the strap collides with the temples. But he does not. Comfort is three to four hours very convincing. After that, it can do something behind the ear to push. But clacking or scrape no annoying or dangle more. The headphones are except the music no side noises. Supremely I find the link width. So I have the gym good eight meters (open space, no walls) removed me from your phone and still had a great signal (no noise).
One should be aware that this is an on Ear Earphones before buying though. This means that outside noise can be perceived. Since the headphones though very noisy but can not be made jet fighter-loud one might be disturbed by other music, for example in the gym.

Conclusion: Kaufempfelung!
