The headphones are way to small for big ear and they're going to hurt after time. At the rest they're pretty good headphones, especially for this price.
The sound is good, battery life is also good, but the padding around the headphones could use a redesign, the ear cups are nice but the headband could be a little more padded
Very fast delivery, good sound good battery,
Happy to shop again...
Great Bargain for what it is, the alexa function doesen't bother
Not a great musical experience , find the sound very flat . I expected more from this brand in terms of sound. A disappointment for music lovers.
