Review on DECWIN Bluetooth Earpiece 5.1: Business Headphones with Mic, Sweatproof & Noise Cancelling - Hands-Free Earphones for Cell Phone by Emanuel Power

I recently purchased a sweatproof hands-free cancelling Bluetooth product in the cell phone accessories category of electronic accessories and supplies. After putting it to the test, I was extremely disappointed with the quality of the sound. While it cancels out external noise, the sound coming through the headphones was very muffled and not clear at all. The only positive aspect was the sweatproof feature. Overall, I would not recommend this product.
