OnePlus Buds Nord/Buds N Truly Wireless Earbuds:

Feature:

• 12.4mm dynamic driver: The OnePlus Buds N earbuds come with a 12.4mm dynamic driver which is tuned for rich bass. They have a 20-20,000Hz frequency response range, and a 98dB driver sensitivity.
• Bluetooth 5.2: Bluetooth 5.2 is supported here, as is AAC codec, and Dolby Atmos. The same goes for the OnePlus Fast Pair (OnePlus 6 and later). The earbuds have dual microphones for AI call noise cancellation.
• IP55: IP55 rating is also a part of the package, which means they are sweat and water resistant. You can easily go work out with them, or get caught in the rain.
• Low latency: 94ms low latency with selected OnePlus smartphones and with Pro Gaming Mode enabled. The latency is a bit higher outside the game mode, same as on non-OnePlus phones, but still very low.
• Play Time: A 41mAh battery is placed in each earbud, while the charging case has a 480mAh battery. Each of these earbuds should be able to provide up to 7 hours of playback, 30 hours with the charging case included.
