I?m a size 8, bought a medium and they fit perfect. I did dishes, went for a walk and cleaned the house and they are in GOOD! The only way I could get them to reconnect was if I put them back in the charging case for a couple minutes and took them back out. They are black powder coated and are thick and feel very sturdy. The assembly was too easy, no directions needed. Posso dire che la qualità del prodotto è davvero ottima, mi piace come è aderente allorecchio, si ascolta una qualità maggiore del suono, si ascoltano bassi profondi, chiarezza dei suoni e poi non si sente nulla dai suoni esterni. Highly recommend this cutie. Pros:Price for the quality is greatDecent speaker/mic soundGood quality cable that is at least 6 longSits comfortably on the headStereo/mic to separate stereo and mic connector includedIn-line mic mute switch and audio volume adjustmentCons:The USB is only a power source for the blue lights on the headset (it is a bit misleading in its uses, but if I had researched it a bit more I would have found this out before purchase)The in-line mute and volume knob would be better with a mic gain knob as wellIt CUTE, well made, packaged beautifully, quality and cool. Very easy to put together and a nice shoe rack?just doesn?t fit any of my doors and I really don?t have a place to mount it on the wall.
