Got this pairabout a month ago, since sole appeared a bit more sturdy. But from February to May they have worn out. So I contacted Amazon to contact the SELLER then received an email from SELLER who told me to contact AMAZON. Upper part looks fine but even at the price of 50. Cable very short. Hubby said after 5 minutes his abs felt a burn. I walk 5 to15 miles per day. Another great feature is the boom mic that can be flipped up and out of the way; lets me take a sip of coffee and mutes the mic. Its even more perfect than what I had before. These may not be good for someones looking for isolation background noise.
