Thoroughly recommended - it comes down to ...

It is definitely on the expectations. If you expect for this price high-end, one should consider whether this is realistic. If you want to experience an ecstatic musical enjoyment, then here it is really wrong. But as I you want a low-priced device for Bluetooth (not a joke), eg background music housework (cleaning up, cooking, ironing, vacuuming, potter, surfing or another on the computer ...) is the headset super.
For this exact purpose I bought it after much back and forth and never regretted.
So far I have heard music from the mobile phone only through the standard Apple headset (in-ear). In above activities me the cable was constantly in the way. Sonically the headset is slightly better than the Apple headset, because the music sounds more voluminous, but as I said, no sound miracle. The comfort is good, pleasantly light and safe to wear. For sporting activities the headset is not suitable, since it it is loose.
The connection works well in a medium sized room. The use and combination (with iPhone and Mac) is light and easily. Charging via USB is quick.
Further reductions but you have to take into account:
The short interruptions during playback described in other recessions I have to confirm. Every now and then there is you. But for my purposes it is hardly noticeable.
However, the warning signal for low battery level is really very pushy and annoying. There is one approximately every 30s repetitive beeping. This can not be shut off well, at least nothing is described in the instructions. The annoying is incorporating the alarm too early. I have driven it out the top and two complete albums A 12 Lider heard after the first battery warning went out without the headphones. The manufacturer should definitely make improvements: beep per switching is sufficiently deactivated, and later again!
The battery life is unfortunately very short on my device. There are felt three hours until the battery warning beeps at me.

Conclusion:
Good value for money and thoroughly recommended, but compromises have to be accepted.
