Review on Cutting-Edge Pack】Bluetooth Earpiece: Handsfree with New Cancelling Technology by Jerry Anderson

So I bought a kit containing 2 of these devices. Since the battery life is very long, it took me some time to use the second Bluetooth. The second Bluetooth is completely useless. When I use it no one hears me or they say I'm very weak. The first Bluetooth in the kit that I have no problems with. The sound quality is good and the noise cancellation is better than other devices I've tried. Now my return date has passed and I feel robbed. Only one of the two I paid for works. If you are lucky enough to get a fully functional device then I recommend this product. However, try both devices before the return period expires.
