Review on Silver beyerdynamic Xelento Wireless Audiophile Tesla In-Ear Headset with Bluetooth Connectivity by Kim Thompson

I think this is a good headset. But this pair I received has many quality control issues. First problem, the wire on the right is much looser than the one on the left. than on the right. And when I press the device on the left side, I hear a sound like some kind of spring vibrating. Not sure why headphones in this price range have this problem. Maybe I'm just unlucky or the quality of the controls is worse because the price has gone down. Anyway I'm going to return it and get a pair of T9IEs because this series is really comfortable. I hope I have good luck with T9IE.
