Oppo Enco M31
The Oppo Enco M31 is a pair of wireless neckband headphones designed for all-day use. The neckband weighs 22 grams and is made of liquid silicone overmolded around a memory titanium alloy thread, so the shape is retained after bending and the headphones can be folded and stored in a pocket. The earbud housings are made of a polycarbonate composite for strength and low weight. Hidden magnets draw the two earbuds together, which disconnects the paired device automatically and saves power. Ldac audio coding supports up to 12 hours of playtime.
