Very poorly made for 200 dollars. I hung this under a high shelf in the kitchen. Was done living the dongle life. Man kann nicht einfach am neuen Gerät verbinden, sondern muss die Verbindung am alten Gerät erst trennen- Ab und zu setzt der linke Kopfhörer kurz aus (Verbindungssynchronisation?). You can then drill the first hole (using the provided drywall anchor if necessary) and put in the first screw just enough to hold the rack. Careful how you store it (bristles up on shelf would be preferred) so bristles do not become distorted. I wear it when I go running, it makes you really hot and sweat, but I guess that’s why I see a difference in my thigh size! Keyboard feels very sturdy and durable compared to the plastic thing I upgraded from and Ive not had any issues mashing numerous keys simultaneously, but you cant control the color without their software installed. I didnt like them. Audio quality is great mic is good.
