No heavier than a decent pair of Ray-Bans. And they fit nicely, even through a strenuous workout session he hearing test option to improve the quality of the sound seems to work really well. I'm very happy with the music output.

Was pretty impressed with the auto translate feature. Battery life was also impressive.

I like the sound profiles. You can use it for music or podcast and it has the ability to customize it to a personal profile. Great sound -
Spatial audio sounds good with this open ear listening.
