The Oppo Enco X3 adopt an in-ear fit and are fully true wireless, meaning there are no cables or neckband involved. They carry an IP55 rating, confirming solid resistance to water and dust ingress during everyday use. The earbuds support stereo sound output but do not include wingtips, RGB lighting, a UV light, or any display. There is no neckband design here — just a compact, wire-free form factor built around straightforward wearability.
The Oppo Enco X3 use an 11 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz. They rely on passive noise reduction to limit ambient sound, as active noise cancellation is not supported. Spatial audio is available, adding a broader sense of dimension to playback, while Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of the hardware configuration.
Each earbud holds a 58 mAh rechargeable battery rated for 10 hours of playback, while the 566 mAh charging case extends total usage to 33 hours. A full charge takes 1.5 hours, and the case supports wireless charging, removing the need for a cable when topping up. A battery level indicator is included, and there is no solar charging capability.
The Oppo Enco X3 connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m and an audio latency of 54 ms. Supported codecs include LDHC and AAC, while LDAC, aptX in all its variants (including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice), and Bluetooth LE Audio are not supported. The charging case uses USB Type-C for wired charging, though fast pairing, NFC pairing, and Auracast are absent from the feature set.
The Oppo Enco X3 support fast charging and can function as a headset for calls, with a mute function available during use. Controls are handled through a panel placed on the device, and voice prompts are included for audio feedback. A travel bag comes in the box for storage and portability. The earbuds do not offer ambient sound mode, in-ear detection for auto-pausing, a find-device feature, notification readout, an in-line control panel, a body temperature sensor, or a camera remote shutter function.
