I bought them for my 14 year old. He seems to like them. You can use as Bluetooth and with a cord. They have radio, mini Sd card and can attach through bluetooth. They are collapsible although my son doesn’t trust the popping noise it makes when you collapse it. Battery life is ok. He keeps a small travel charger to charge it up. He downloaded music on the mini SD card so he doesn’t have to have his phone on him to listen to music. Overall well worth the price we paid.Use these headphones as a multi-taking function - for my computer. During the day = business and at night, I stream a movie or listen to good music to relax. Excellent versatility. Will purchase again for other family members.very good sound for the cost. earphones too small to fit right on your ears. battery gives only 3 hrs. of continuous use before having to charge it.Quite charging after just 3 months. Cheaply made.They are very very cheap plastic. They do notCancel noise and they may possibly break if they are dropped 1 time. I don’t recommend them.Simply terrible. The headphone came with the left side of it not working and even the right side side was very low quality sound. Hope the replacement will work. Another issue, I sent the broken headphone more than two weeks ago, but I still haven’t received the replacement. I need the headphone for my online class and I’m still waiting. Crazy. I don’t know why I didn’t just cancel that crap and order another one with another seller? Bad decisionGreat value and comfort.
