Review on 👓 Dulailt Smart Glasses: Open-Ear Bone Conduction Glasses with Photochromic Grey Lenses and Blue Light Blocking - IP6 Sweat Resistant Bluetooth Glasses with Music, Microphone, and 250mAh Battery by Carmen Morris

Looks decent but is not loud enough and distorts the sound at maximum volume. You won't hear it if something else is going on around you. Warning, Revain will not take it back because apparently it contains dangerous materials (never mind, they had no problem bringing it to you from the start). Bottom line is that you'll save money and have more fun with cheap photochromic glasses with lots of style ($15) and a pair of $50 headphones.
