These speakers deliver great sound quality. I ordered them immediately. My husband has a lot of caps people give him, plus the ones he buys. None of them were personally any good for me. The slippers are an inch longer in length than my actual size and the toe box was a half inch too big around. However, in the photo, it advertises as six feet and these are most definitely not six feet. Not a big deal, but with the black case, it is really noticeable. The biggest issue I have though is they slide off my head when I bend over and they dont do a wonderful job with cutting out the background noise. Works perfect, quick shipping. Told him to concentrate instead on reviving the dead earbud.
