Exactly what I needed to keep Tv sound downstairs and not wake my wife upstairs during late night action films🤗the control switches are a little tricky for an old guy but I got them finally
I ordered twice right after a week that I got the first one. I did not even know that this is really awesome headset. I don't know if I read it or not but it is also water-resistant (of course you're not gonna swim with this one. No, no) It's good even when it's raining especially in Denmark ✌️. I can't express how good is this one. Just the brand itself is enough. But... The item also was perfect! More than perfect. It waaas awesome. Worth it every penny.
Great but a bit uncomfortable for me on the ears
Ich bin sehr zufrieden mit dem Produkt. Keine großartigen Features, aber genau das, was man braucht: einfache Tasten und leicht benutzbar.
