What's in the Box
Good sound for under 100 Euros. After a few hours of wearing, the ears are hurting a little. But I wear them very long time. The Akkumulator is very long lasting and the connection is realy fast with mobile fone. I would buy these headfones again!
Excellent produit, remis à neuf et facile d'utilisation, envoi très rapide et soigné, comme neuf ! Je recommande
Was a bit sceptical at first, but the product was worth it. Quality is great, sound is great, as of now no complaints. As a person wearing glasses, it takes a while until you get used to having headphones over them, so at first it might pinch a bit behind the ears (maybe also depends on what kind of glasses you have..).
Ear cups fit perfectly around my ears.
Bought these for our 12-year old. Great value and quality at this price.
Might be a little small for an adult head, but perfect for the tweenager!
Great headphones. Works flawlessly and has a very good sound. The connection with multiple devices works great.
