Sanag B21S Bone Conduction Earphones - Bluetooth 5.4 Sports Headphones
This headset experience a week after the feeling is to wear a very solid, high fit, movement is not afraid of falling out, wear senseless, wear a long time head will not be distended, there is no noise phenomenon, no sound leakage at all. Outdoor running or swimming is very useful, you can pay attention to the outside world sound, can let us enjoy the music at the same time attention to safety issues!
Package less than two weeks to receive, the sound quality is particularly good, whether it is the treble, midrange, bass are able to perform very unexpected, wear a long time ear will not be swollen and painful, the range is also particularly excellent, the texture feel is also very good, cost-effective is really high, recommended!
Received the wrong color. Ordered black received blue. Plastic feels cheap… sounds not bad. Package comes damaged. Package quality can be better.
