These headphones are just great. You can walk, ride a bike with them, they fit under any helmet. The sound quality and the price are top. I had it for 1 year since I've now bought at Euronics. Just because an idiot has torn me it was the right side now a wobbler and spinnte, knirschte- about neukauf!
Each of the good in-ear speaker without the typical problems, sitting with gutem- firm and great sound for little money want
The only drawback is that if the rubber stopper dissolve times it is a very nice fumbling to sit properly again.
