The F-01 is a pair of sunglasses with small speakers built into the temple arms, so you hear music and calls while your ears stay open to traffic, teammates and surroundings. It pairs over Bluetooth to a phone and has a microphone for hands-free calls. It suits cyclists, runners and walkers who want sound without earbuds blocking the world out. Against rivals like Bose Frames and Amazon Echo Frames, the F-01 is a basic open-ear design: no voice assistant, no prescription lens options and no published battery or water-resistance figures. Sound from temple speakers is thin on bass and leaks to people nearby, which is the trade-off every open-ear pair makes.
