SonaVue Smart Audio Sunglasses put open-ear speakers into a gloss black acrylic frame, so you can listen to music, take calls and translate a conversation without putting anything in your ears - and still hear the traffic and the people around you. The lenses carry a deep grey tint rated for bright sun, with full UV protection independently certified to international eyewear standards. Around 11 hours of listening on a charge, and a 10-minute top-up buys about two more. The free companion app adds real-time translation across 159+ languages, included for the life of the product. | Harmonix | | SonaVue Smart Audio Sunglasses | Open-Ear Bluetooth, Category 3 UV400 Lenses | Black | Best Buy
