Emotive, engaging, detailed sound Wide soundstage Excellent fit and light weight for lasting comfort Superb choice for vigorous exercise Fast USB-C charging The OnePlus Bullets Wireless earphones use Bluetooth v4.1 connectivity and support Qualcom aptX technology that's touted to provide high-quality audio across a Bluetooth connection. They feature 9.2mm drivers, and the company's Energy Tube technology to stabilise sound as it passes through. The Energy Tubes are composed of a non-metallic mineral and silica gel, and reduce frequency distraction and noise generation. The Bullets Wireless also feature magnetic switches. Amongst other features, these allow users to stop playback by putting the two earbuds together - these then magnetically attach, stopping playback. Users can resume playback and take calls simply by pulling the attached earbuds apart. They also feature an in-line remote control. The neck band features a button for power and pairing, as well as the input for Dash Charge. Brand OnePlus SKU 100028071_NP-1019407054 Model BT318
