Unusable. The volume is so low that even in very quiet places you can hardly hear anything. They are cheap but not even worth the price.
Bought out of necessity and immediately regretted it. They fit poorly and I can't hear anything most of the time. The volume is limited and I can't hear anything when there are noises around me. It was particularly annoying that I was refused a return for hygiene reasons.
Super emergency solution
I had them for three days, then one of the headphones stopped working, but actually great sound for the price.
Use my sweetheart
Basically good headphones. good sound. Great range and running time. good price-performance ratio. BUT as already mentioned in other comments, after approx. 2 months the right earphone no longer works and is therefore unusable. if you buy them, don't "dilute" the warranty under any circumstances
The battery life is good the quality of the music for the price totally ok, unfortunately the loudness is not so high there could be improved. but for the price it is a good product.
Cheap and good
Très bon rapport qualité-prix.
Good price performance.
