TL; DR: Nearly perfect for the price. Only negative is that it is slow to change songs.
Comfort: 8/10. They feel slightly tight, but at the same time you have large pillows that feel comfortable against the skin.
Sound: 9/10. Very good, especially for the price! Low, strong bass sounds and a very clear treble. Possibly the base could have been a bit .... "different" (?). It's strong and good, but somehow it doesn't feel perfect. A little hard to explain. However, nothing you think about when you're on the go. By the way, there is really nothing inside them, and "noise canceling" should hardly play any role here. By the way, they sounded twice as good as Urbanista New York, for the same price.
Battery life: 10/10. 30 hours with good bass and high volume. Can't complain about it simply. Maybe I would have liked a USB-C connector on them though.
Functionality: 8/10. Have used "pass-through" often when talking to cashiers a little quickly. Just push a button and you hear the headphones with light. There is built-in support for Google Voice / Alexa, but it did not work as well. Mainly because I only listen to music through PowerAmp, and Google's assistant doesn't support it very well. But also that it was a little complicated / unreliable to activate the assistant, which you do by putting your hand on the left headphones .... then it works.
BT connection is clockwise, 10/10, good range and stability.
It takes a long time to change the song, as you have to hold "volume up" for 2 seconds. It's a long time, and under all criticism (should be double-taped), but I'm glad I didn't have to pull up the phone at least.
Other: Besides there is not much to complain about. Not the nicest handsets on earth, but for what you pay you get good things anyway. The sound is nice and good, battery life good, and comfort good. That's what counts anyway. Maybe they feel / sound a little plastic too. If you want to avoid it, buy headphones with a metal bow ("hinge", by the handsets).
