The headphones here high-quality workmanship and fit for purpose. Included is a charging cable with a USB port and a jack cable when the battery is surprisingly empty.
You can change the volume, pre-tilt a title, start and stop music on the headphones. The battery lasts a long time. I've been using it for about 1 hour a day and once a week must load. Where he is not then completely empty.
The strap can be adjusted well and fit on the ear is very good. He also dampens the surround sounds very good. And it is very stable. One must not be afraid that he takes damage, if you use it a little bit bumpy.
A deduction of points there, because it crackles over Bluetooth easily if you have the music means to loud. I suspect that this is due to the membranes. But can not say with certainty I. Of course, one could say that one can not expect more for 40 euros, but a clear sound should hammer out any headphones.
But since I do not mean to listen to classical music in complete silence, it is not a big minus. All in all: want to spend a strong buy recommendation for customers who want to have a solid Bluetooth headset and not several hundred euros for a beat.
