The Anker Soundcore P31i use an in-ear fit and are designed as true wireless earbuds, meaning there are no cables or neckband involved. They carry an IP55 rating, confirming resistance to dust ingress and water splashes. Stereo speakers are present, while features such as RGB lighting, UV light, wingtips, and a display are not included in this model.
The Soundcore P31i feature an 11 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz. Both active noise cancellation and passive noise reduction are supported, giving the earbuds two layers of sound isolation. Spatial audio is also on board, while Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of this model's configuration.
The Soundcore P31i have a rechargeable battery offering 10 hours of playback under standard conditions, which drops to 8 hours when active noise cancellation is in use. The included charging case extends the total available battery life to 40 hours, and a full charge takes 2 hours. A battery level indicator is present, while wireless charging and solar power are not supported.
The Soundcore P31i connect wirelessly via Bluetooth 6.1 with a maximum range of 10 m, and fast pairing is supported for quicker device setup. Supported audio codecs include LDAC and AAC, while aptX in all its variants — including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice — as well as LDHC and Bluetooth LE Audio are not available. Audio latency is rated at 50 ms, and NFC pairing and Auracast are not supported. The charging case connects via USB-C.
The Soundcore P31i support fast charging and can connect to up to two devices simultaneously via multipoint pairing. An ambient sound mode, mute function, and voice prompts are all included, and the earbuds can be used as a headset for calls. A notable addition is the built-in translator feature, alongside a control panel placed directly on the device. A travel bag is included in the box. In-line controls, a body temperature sensor, notification reading, and a camera remote shutter function are not part of this model.
The Soundcore P31i are equipped with a noise-canceling microphone, which helps reduce background noise during calls and voice input.
