The Realme Buds Air 8 feature an in-ear fit and are fully true wireless, meaning there are no cables or neckbands involved. They carry an IP55 rating, classifying them as water resistant against splashing from any direction as well as limited dust ingress. The earbuds include stereo speakers but do not feature wingtips, RGB lighting, a UV light, or any built-in display.
The Realme Buds Air 8 use an 11 mm driver unit with a frequency range spanning 20 Hz to 20,000 Hz. Both active noise cancellation and passive noise reduction are supported, allowing for flexibility in how ambient sound is managed. Spatial audio is also available, adding a wider soundstage to playback. The earbuds do not include Dolby Atmos, Dirac Virtuo, or a neodymium magnet.
The Realme Buds Air 8 offer 14 hours of battery life per charge, which drops to 8 hours when active noise cancellation is in use. The included charging case extends the total available playback time to 34 hours. A full charge takes 2 hours, and the earbuds feature a battery level indicator so users can monitor remaining power. The battery is rechargeable, though wireless charging and solar charging are not supported.
The Realme Buds Air 8 connect wirelessly with a maximum Bluetooth range of 10 m and an audio latency of 45 ms. Supported audio codecs include LDHC and AAC, while LDAC, aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice are not available.

Controls are handled via a panel on the device itself, with no in-line control panel present. The earbuds do not offer notification readout, a built-in translator, a body temperature sensor, or a camera remote shutter function.
