In recent years, Bose and Amazon both have released eyewear products with built-in speakers. JLab Audio takes a slightly different approach. With JBuds Frames, you can attach a pair of two true wireless open-ear speakers to the temples of any glasses, so you can swap them between your usual glasses and sunglasses. JLab includes several silicone sleeves to support a variety of eyeglass temple sizes.
The speakers, which weigh 11.7 grams each, have 16.2mm drivers and an IPX4 waterproof rating. JLab claims they can run for up to eight hours on a single charge, although you have the option of using only one speaker at a time to save battery power.
