The described headphones I have not advertised on Amazon. The price is similar to the offline on Amazon. The initializing coupling the headphone via Bluetooth with my iPhone 5S (iOS 8.1.2) went smoothly. The next time you start Bluetooth (or headphones) the Reconnect is automatic. If this is not the case, the Play button must be pressed once. Then you can see the charging status of the headset next to the Bluetooth icon in the iPhone screen. The management of multimedia content directly worked without any problems, even Siri can be operated. So far I had no disconnections and after about 4 hours listening to music, the display of the battery did not like. The stated 12 hours have realistic or even surpass. I must say that I do not hear the music very loud. What is also not recommended in this headphone because of the high maximum volume of 105dB! Charging is via USB to 2.5mm jack plug. All of the buttons of the headset are located at the left earpiece, have a good pressure point and respond pleasant. Likewise, there is the aforementioned jack plug here. The integrated microphone is also on the left side (below, next to the On / Off switch) fitted and could even cut satisfactorily in windy weather. Respect, telephoning can cope with the headphones also.
Sound / comfort / perception:
The sound of this headset is extremely good. Press the bass, the treble and midrange are clearly perceptible. I do not feel the sound as mushy or too much bass. Relevant for this are, of course, the playback source, the type of connection and the equalizer used. The test with classical music (Ludovico Einaudi), Metal (The Ghost Inside, Lamb of God,) and electronic music (hardcore / gabber, techno and Goa) has passed with flying colors for me the headphones. Sound is and remains a subjective sensation. Those who love music, love and a lot of it is listening, which is definitely not fret here. I have compared the headphones with those of Bose and other well-known manufacturers. For me, he can keep up. Wear after 2 hours I felt the headphones on the bracket goes over my head. It was not unpleasant, but still noticeable. The earcups are sufficiently well padded and keep even the ears warm. However, one feels a little like an alien, but that is probably due to the unusual headgear. The shield from the outside world succeeds very well, even if this is no active technology is used. The bluish side panels may have to be somewhat inconspicuous. To this end, the installed keys light up only when they are pressed. This saves on time with safety on battery performance.
Accessories / This and That:
In the accessories there is a kind of neoprene / plastic bag with zipper. This even 2x grid compartments are sewn. Here also a 1.5m 2,5mm- is on 3.5mm jack cable (for audio connections) and the approximately 0.5m long USB jack on charger. There are also useful manuals. Round so you can be satisfied with the facilities. The headset looks a little inferior defying the price - but this is probably just the plastic. Still, I did not feel that the headphones would go directly broken by a fall. The sound via cable I have not tested. But I assume that this will be just as satisfactory. If the playback source hergibt enough power.
For further information or images, I am happy to help.
