The first positive thing that strikes one is the processing. Priced at 40 euros I had nothing insane quality expected. But no matter how you bend the headset, it cracks and creaks nothing. Only the retractable on-ear speakers may wear out over time. Otherwise there is nothing to complain about here.
The commissioning works fine. I did it once charged overnight (12 hours recommends the manual), then the battery lasts estimated around five hours. Sufficiently long so.
The connection via Bluetooth worked well with no problems, as the device uses the standard 2.1, so older devices are still available, as my iPhone 4 for example.
About Bluetooth to the smartphone can also be easily controlled because the Headset to make buttons for the music louder or softer to change songs, contrary to take calls, and so on. As a range of the manufacturer are here the way to ten meters. In my old apartment, but broke after about four meters from the music playback.
The sound quality fits here. Music comes clear out of the speakers, bass are noticeable yet, but keep still pleasantly in the background. All in all, the headset sounds balanced and well, unless you turning up the volume too much.
Strange is here but that the sound decreases when the headset is connected by cable to the smartphone (or whatever). About the cable, the headset works basically even then, when the battery should be empty, but recommended is not. When trying out, I realized that the music cable operation sounds muted and no longer as balanced as via Bluetooth.
Once the headset but when headset is used, it begins to weaken. While even understands his opponent well, you yourself are too soft and difficult to understand. Especially in outdoor areas you can almost forget a telephone call actually.
Therefore, I would advise anyone who is looking for a good, cheap Bluetooth headset, with which he can make a call even for emergency times, recommend this headset. Who on the other hand requires a full and good headset, which is likely to be sadly disappointed.
