The ROCKBROS Bluetooth Cycling Sunglasses are polarized cycling glasses with built-in Bluetooth audio, so you can take calls, play music and hear navigation prompts without touching your phone. They weigh 43g, use TAC polarized lenses with UV400 protection, and have a half-frame design. That puts them against plain sports sunglasses on price and against bone-conduction headsets on audio privacy. Riders who want one piece of gear for eyes and sound will find them appealing; anyone who needs hi-fi audio or prescription lenses should look elsewhere.

These cycling sunglasses combine polarized lenses with built-in Bluetooth, so riders can handle calls and music without handling their phone. The TAC polarized lenses reduce glare and reflected light from roads, water, snow and glass. They also have UV400 protection.
The frame is made of durable TR material in a half-frame design and weighs about 43 g. Ergonomic ear hooks and an adjustable nosepiece are built in for a comfortable fit on long rides. The lenses are treated with laser engraving technology to resist scratching.
The glasses connect to a smartphone over Bluetooth. One-touch controls manage calls, music and navigation prompts. Pressing the function button four times in a row activates the phone's voice assistant.
