I have purchased now, I believe a total of 7 pairs of various models of TOZO earphones and earbuds, including 3 pairs of these Openreal headset earphones. I bought a pair of earbuds for a friend and she tells me they aren't as loud as they were originally, but still likes them. I bought 4 pairs of TOZO T-10s because I lost one pair temporarily but later found them. One earbud in a pair stopped working and one of my dogs destroyed another earbud from a different pair. I currently have two pair of these Openreal in black, so I can't have one on charge while using the other. I think they're great. When it comes to earbuds; prior to these, I owned some expensive ones that sounded okay, about the same and one of the pair by a brand I won't name publicly cost just Pennie's over $300. When they stopped working about 4 months after I bought them, I contacted the manufacturer and they offered me a gift certificate for $25 off another pair. That is one of two expensive pairs I tried prior to taking a chance on TOZO. I won't waste time with any other brand now.
