Bin of this headset very impressed. Sound is good for a Bluetooth headset. Although basses do not penetrate deep enough, but that does not stand out particularly, if you are not similar from Beyerdynamic changes to this headphone. Lying good and pleasant to the ears. But what especially strikes and a very big plus point of wireless headphones is the sensational battery life. It begins with the fact that I did not manage the battery charge has been delivered to the headphones to use completely within one day! (That one should supposedly for optimal battery maintenance initially make). Use the headphones usually while working and at times when sports and he is holding a whole workweek by. How many hours are exactly is hard to say, but the headphone battery lasts in any case, often longer than by the mobile phone battery of my Galaxy S4. Now we come to heading: The design is getting used for sensitive eyes. The sharp-edged, mounted in series rectangular Ingen buttons are probably not for the people who place more value on the appearance rather than the technology. What you have also mentioned, is that some beam of sound to the outside. So if in the train with this headphone listening to loud music, will probably have to take the odd dirty look in purchasing. But as I said, that's to complain at a high level, because the price-performance ratio is really good and I can recommend the very MEElectronics and would like to see that the company is more widespread in Germany. For comparison: Customer rating from amazon.com is 4.3 stars in over 1,200 reviews.
