Letsfit Wireless Headphones is a lightweight Bluetooth headphone waterproof with a noise-canceling feature. The headphones are designed to last for years. They allow you to listen to music, make and receive calls without interruption. Compared to other headphones, the sound quality is not so good. The bass is a bit overwhelming, although you can adjust them a little with an equalizer. Many consumers also say that this headphone isn’t suitable for running, because if you’re on the treadmill it may fall off your feet.
