I consider myself a technology enthusiast, and hands down this is one of the best items I have seen in years. I receive constant complaints on the Dusk sunglasses as well as the the recharging case. As a matter of fact I should probably get a commission for promoting this product. My optometrist was in aw and asked for the information which I gladly gave. AMPERE prepare for an explosion in sales. Your welcome.
It is almost the perfect product. I don't have to remove my sunglasses and try to find some space for them anymore. The sound is clear and pleasant, albeit a little quiet and almost inaudible near traffic or general background city noise, hence the four stars. Pads that sit on your nose lose their adhesive and get loose. The microphone works great but makes people look at you as if you are crazy since there is no visible earphone. I'm pleased with it.
Leisure walking, beach side, pool side, early morning audiobook, these things have permanently changed experience wise, by Dusk. Remarkable. The bass is what you would expect but overall it's a technological marvel.
I love them! The fit is just ok, but the functionality is amazing. Being able to darken and lighten the tint of the glasses on demand is such a luxury. I also like the earbud-free sound. You can hear everything including what is happening in your surroundings. There is no real bass and it is not super loud but it is good enough. The battery charges easily especially if you bought the charging case, which I did! Anway, I like them a lot and would recommend them to everyone.
