Description
realme Buds T300 wireless earbuds
True wireless in-ears from realme combine 30dB active noise cancellation with a 12.4mm dynamic bass driver, spatial audio, Dolby Atmos support, and extended battery life with quick top-ups.
Listening signature
The 12.4mm Dynamic Bass Driver measures about 24% larger than the earlier 10mm unit, aiming for fuller low end, a broader soundstage, and cleaner vocals. A 360° Spatial Audio Effect wraps sound from multiple directions for a more immersive stage. Dolby Atmos widens the presentation for games, films, and tracks.
Quiet mode
Active noise cancellation reaches up to 30dB to reduce ambient noise so music, podcasts, and calls stay clearer in busy settings.
Runtime and quick charge
- Up to 40 hours total playback across case and buds—enough for roughly a week at five hours of daily listening in manufacturer examples
- About 10 minutes on the charger returns around 7 hours of music playback
Gaming response and outdoor use
50ms ultra-low latency targets responsive mobile gaming. IP55 rating resists dust and handles sweat or splashes during workouts and light rain.
Pairing and app control
Bluetooth 5.3 handles wireless connection. The realme Link app adds settings on Android phones only.
