Review on SLuB Bluetooth Headphone Microphone 180°（Blue） by Darby Perkins

According to my experience, these in-ear headphones were a complete waste of money .Despite being advertised as "noise-cancelling" they let through almost as much sound as if they weren't there at all. The worst part was the sound quality, which was tinny and poorly balanced. On the plus side, the battery life was decent. Overall, I do not recommend buying these headphones..
