They are very helpful and answer any questions super fast. alles schon geschrieben. Looks nice. My $50 Logitech wireless headset, at least, displays on screen whether Im muted or not. It feels sloppy to me. 5/5: Before I get into anything to do with sound, Im gonna talk about the actual headphones. Durable amazing quality, a little larger than I expected but I love the leather! My feet eventually got over the scratchy straps (I now have small scars on the top of my feet from the straps), but after walking around in extreme heat with so much extra weight on my body, I experienced no arch or shin pain. We got these for our 9 year old son. The headset does what you expect it connects via Bluetooth and plays music, calls , etc with good quality and performance.
