Good product with its pitfalls

Have ordered the headset for listening to music and run through the apartment. After charging I was unable to use immediately. Handling is easy, even with the software is easy to handle. The setting of the ups and downs can be adjusted individually in an equalizer. The sound is very full and makes you want to use the headset's.

However, it has already passed after three months (proper) use of the bass. It was only to hear a no longer controllable "crash" at each deeper tone. Why was I can not say, have the unit just sent back to Amazon and look forward to a hopefully familiar as Amazon smooth unwinding.

Maybe it works the next attempt with another device better. Since the device until it broke because fully satisfied my CLAIMS THAT it gets from me three points.

Can the product thoroughly recommend, perhaps the defect was only an isolated case, but I would like a product that I can rely 100% and does not have to constantly send in repair.
