Review on Bluetooth Headphones Reduction Earphones Waterproof Headphones by Ryan Price

After receiving these headphones I did a sound test. They go down to around 25 Hz at low frequencies and up to around 15,000 Hz at high frequencies. Both have excellent marks. They sit very comfortably in the ears. Thanks to their design, they fit snugly and stay in place while you move. The battery life is amazing. I use them to listen to videos most of the day at work and none of them got disconnected. You can use them individually or in pairs for stereo sound. They come in a rechargeable case that holds a charge so you can charge your headphones on the go. I carry the case in my bag in case I need an extra boost throughout the day, but I don't need it now. Excellent goods. I would buy again and recommend to my friends.
