Best Bluetooth audio glasses and sunglasses for 2021

Audio glasses, which have integrated microspeakers and a Bluetooth connection, are multiplying. Bose is leading the way with its Frames audio sunglasses. Amazon is also in the Bluetooth-glasses game with its Echo Frames, now on their second generation. A host of other companies, many of which are no-name Chinese manufacturers, have released audio glasses in recent months. Some are geared toward everyday use, allowing you to forgo headphones and stealthily listen to audio on the go, while others are designed for runners and bikers who want to leave their ears open to the world for safety reasons.
