This product doesnt hurt my ear even if I put it in my ear for along time. This could seriously have ended in divorce, but I thought Id try ear plugs first. Im writing thiss review using my sssecond k95, the first one i haad to return due to similar errors. One thing I could of done without was the nearly superficial love triangle that Percy found himself in. However on a full charge, it only runs 2-4 cleaning cycles. Most of these sellers are just thieves. This is an awesome little speaker! every time you open the case the cover pop off 1* Abzug aufgrund der geringen Haltbarkeit. I feel much more positive about the smaller trash footprint (pun intended) that the insoles make compared to pairs of Crocs.
