The Realme Buds T200x use an in-ear fit and are fully true wireless, with no cables or neckband connecting the two earbuds. They carry an IP55 rating, meaning they are resistant to both dust ingress and water splashes, making them reasonably durable for outdoor or active use. Stereo audio is supported, while features such as RGB lighting, wingtips, a display, and UV light are not included in this model.
The Realme Buds T200x feature both active noise cancellation (ANC) and passive noise reduction, giving them two layers of noise management for blocking out unwanted sound. Audio is handled by a 12.4 mm driver unit with a frequency range spanning 20 Hz to 20,000 Hz. The earbuds do not support spatial audio, Dolby Atmos, or Dirac Virtuo, and they do not use a neodymium magnet in their driver construction.
The Realme Buds T200x offer 7 hours of battery life per charge, with the included charging case extending the total to 41 hours. A full charge takes 1.5 hours, and the earbuds support fast charging for quicker top-ups. A battery level indicator is built in, and the battery is rechargeable, though wireless charging and solar power are not supported.
The Realme Buds T200x connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m, and support the AAC codec for audio transmission. Audio latency is rated at 5 ms, and the charging case uses USB Type-C. Higher-end codec options including LDAC, LDHC, aptX and its variants, and Bluetooth LE Audio are not supported, nor are fast pairing, NFC pairing, or Auracast.
The Realme Buds T200x include an ambient sound mode and a mute function, and they can be used as a headset for calls. Controls are placed directly on the earbuds, and voice prompts are supported, though there is no in-line control panel. Multipoint connectivity allows simultaneous pairing with up to 2 devices, and fast charging is also supported. A travel bag is included in the box, while notification readout, a built-in translator, a body temperature sensor, and a camera remote shutter function are not available.
The Realme Buds T200x are equipped with a total of 4 microphones alongside a noise-canceling microphone function, helping to reduce background noise during calls and voice input.
