Review on Wireless Earbuds with Apple W1 Headphone Chip, Class 1 Bluetooth, and Magnetic Design - Beats Flex in Black, with 12 Hours Playback and Built-in Microphone by Nakaishi Kiyoshi ᠌

In general, the headphones lived up to expectations. They connect to the iPhone by holding the power button, animation, charge, that's all. Microphone—as in Apple headphones. Not super cool, but it will do. The sound is good. Pop, electronic, hip-hop and other genres in which the lower classes play an important role are reproduced with dignity. Rock, metal, classics are not about them, but you can listen, frankly I won’t call the sound bad.
