Very comfortable to wear when I'm cycling and the sound quality is perfectly placed. This helps me be aware of my surroundings. I would never wear ear buds or headphones.
Looks great and actually adjusts tint percentage as advertised. It would be 5 stars, but the tint adjuster on the side of the glasses do not work properly 75% of the time. It takes many tries for it to work correctly. Other than that, I love them.
I used to carry a Bose Tempo and recently switched to a Music Shield. I love the glasses so much when I need it tinted I use it especially outdoor exercises especially hiking and cycling. I highly recommend this and in the future get an Auro.
