The Bluetooth version uses 5.0, which has a wide communication range and a high data transfer speed, and achieves stable wireless performance. It also supports wired connections, so you can use them properly. Equipped with a large diameter 50mm driver, it outputs low frequencies with contours that you wouldn't think of as headphones.
