The Anker Soundcore P25i use an in-ear fit and operate as fully true wireless earbuds, with no cables or neckband connecting the two units. They carry an IPX5 rating, meaning they are water resistant and can handle sweat and light splashes without issue. Each earbud houses a stereo speaker, while features such as wingtips, RGB lighting, a UV light, and a display are not included in the design.
The Soundcore P25i covers a frequency range of 20 Hz to 20,000 Hz and relies on passive noise reduction to limit ambient sound, as active noise cancellation is not supported. The earbuds do not include a neodymium magnet, and there is no support for spatial audio, Dolby Atmos, or Dirac Virtuo processing.
The Soundcore P25i offers 8 hours of battery life per charge, with the included charging case extending total playback to 24 hours. A full charge takes 1.5 hours, and a battery level indicator is on hand to keep track of remaining power. The battery is rechargeable, though wireless charging and solar charging are not supported.
The Soundcore P25i connects wirelessly via Bluetooth 5.3 with a maximum range of 10 meters, and charges through a USB Type-C port. Fast pairing and NFC pairing are not supported, nor is AAC codec playback. On the audio codec side, none of the aptX variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — are available, and LDAC, LDHC, Bluetooth LE Audio, and Auracast are equally absent.
The Soundcore P25i supports fast charging and can be used as a headset, with onboard controls handled through a control panel built into the earbuds rather than an in-line panel on a cable. A mute function and voice prompts are both included, and a travel bag comes in the box. Ambient sound mode, in-ear detection, notification reading, a temperature sensor, and a camera remote function are not part of the feature set.
The Soundcore P25i is equipped with four microphones and includes noise-canceling microphone technology to help reduce unwanted background sound during calls and recordings.
