Review on Bluetooth Earbuds with Microphone: IPX7 Waterproof, 8 Hr Battery Life, CVC Noise Canceling - Perfect for Any Exercise! by Brad Cao

- (minor) The charging port cover doesn't fit well and looks like it will fall off after a few weeks of use. The charging connection is also too tight on the cable, it has to be clamped a bit. Pairing with IPhone6 always requires restarting Bluetooth. And even then, the connection sometimes spontaneously breaks off ("out of range"), and sometimes it spontaneously resumes. At some point, the headphones simply refused to turn off. Constantly audible "power on" after pressing the power button. After a while he went back to normal. The left earbud emits noise (the right earbud is fine). It's the nail in the coffin.+ On the plus side, the earbuds are very comfortable. Of course we will send them back.
