I'm on my 4th or 5th copy and I never tire of these headphones, which are not perfect but still one of the best quality / price ratio on the market, despite the explosion of the offer. However, they also kept the same default, the fragility of the jack, which in mobile use, inevitably ended up giving up the ghost one day or another. Too bad if the price increase was offset by the resolution of this defect, it would deserve a 5 star rating!
