Customer Reviews
Kopfkörer kam wie Neu an. Nicht zu erkennen das es B-Ware wäre. Das nenn ich Nachhaltigkeit! Weiter so. Jedoch im Vergleich mit andern Kopfhörern könnte der Klang besser sein. Aber für meinen Garten-Sound und Handy Telefonie ist es ein Top Gerät.
Just Good….
Price, Quality and Brand….
That's all, they are good.
Comfortable to wear for hours.
Annoying beeping was resolved by firmware update. However I hate having to install an app on my phone to use the headphones with a laptop.
The buttons are small and plenty, but I don't need to use them, apart from turning the headphones on and off.
My CX true are good too, everything works great is just because I didn't read peacefully the menu, I was thinking my Momentum doesn't work but it works great thank you
Der Kopfhörer ist super passt super keine Druck Punkte oder sowas! Klang mega nice! Dürfte ein wenig lauter sein! Benutzt den fürs Training und da könnte er Bissl lauter sein
