These true wireless outdoor bluetooth earphones are amazing. The speakers sound amazing. The sound is super crisp and yet you can safely hear your surroundings when running. The earphones are very comfortable in your ears. And due to them being wireless there is no cord to rip the speakers out of your ears. The plastic and wires are made of very high quality material for the price. These headphones are going to be able to take a beating due to working out. Overall great buy and I highly recommend.
