The Poco Buds X1 use an in-ear fit and are fully true wireless, meaning there are no cables or neckband involved. Each earbud weighs just 8.4 g and carries an IP54 ingress protection rating, making them sweat resistant during physical activity. They feature stereo speakers but do not include wingtips, RGB lighting, a UV light, or any onboard display.
The Poco Buds X1 include both active noise cancellation (ANC) and passive noise reduction, offering two layers of isolation from background sound. Audio is handled by a 12.4 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz. The earbuds do not support spatial audio, Dolby Atmos, or Dirac Virtuo, and the driver does not use a neodymium magnet.
Each earbud holds a 45 mAh rechargeable battery delivering up to 7 hours of playback, while the 480 mAh charging case extends the total to 29 hours combined. A full charge takes 1.5 hours, and a battery level indicator is included to keep track of remaining power. The earbuds do not support wireless charging and have no solar power capability.
The Poco Buds X1 connect wirelessly via Bluetooth 5.3 with a maximum range of 10 m, and support fast pairing alongside AAC codec for audio transmission. Audio latency is rated at 60 ms, and the earbuds charge through a USB Type-C connection. Advanced codec support is not included — there is no LDAC, LDHC, aptX in any of its variants, or Bluetooth LE Audio — and neither Auracast nor NFC pairing are available.
The Poco Buds X1 support multipoint connectivity for up to two devices simultaneously and include an ambient sound mode, a mute function, voice prompts, and a control panel on the device itself. Fast charging is supported, and the earbuds can function as a headset for calls. A travel bag is included in the package. On the other hand, there is no in/on-ear detection for auto-pause, no find-device feature, no notification readout, no in-line control panel, no body temperature sensor, and no built-in camera remote function.
The Poco Buds X1 are equipped with four microphones and include noise-canceling microphone technology to help reduce unwanted background sound during calls and voice interactions.
