Casque Nothing Ear (a)

Nothing Ear (a) is a True Wireless Stereo in-ear headset designed for music and calls. The earbuds and charging case continue Nothing’s transparent design language with a new bubble-shaped case and a slim rectangular frame that is lightweight (49.2 g total, 4.8 g per earbud). The product is offered in a distinctive yellow transparency and features advanced audio and connectivity technologies including LDAC support and USB-C charging.

Advantages

Ear (a) provides up to 45 dB of active noise cancellation with Smart ANC that detects ear seal leakage and adapts accordingly, plus an Adaptive ANC mode that adjusts in real time via the Nothing X app. Sound is driven by a powerful 11 mm driver, supported by a Bass Enhance algorithm and Hi-Res Wireless Audio certification (up to 990 kbps, 24 bit/96 kHz). Battery capacity improvements extend playback to up to 9.5 hours per charge and over 42.5 hours with the case (ANC off). Additional features include Clear Voice Technology for clearer calls, Dual Connection for two-device pairing, Low Lag mode for gaming, Fast Charge (10 min → ~10 hours playback with ANC off) and integration with ChatGPT on compatible Nothing phones.

• Listening to music with enhanced bass and high-resolution streaming
• Phone calls in noisy environments using Clear Voice Technology

How to use

Charge the case via the USB‑C port before first use and pair the earbuds with your device using Bluetooth. Insert each earbud into the ear canal for a proper seal; Smart ANC will automatically detect leakage and adjust noise cancellation. Use the Nothing X app to select ANC levels, enable Adaptive ANC, configure Fast Charge settings, and set up ChatGPT or voice control where supported. For calls, position the stem mic toward your mouth to benefit from Clear Voice Technology. Reinsert earbuds into the case to recharge between uses.

Recommendations

For best noise-cancellation and bass performance, ensure a good ear seal by trying different ear tip sizes. Enable Adaptive ANC in the Nothing X app for automatic real-time adjustments. Use LDAC when streaming from devices that support it for the highest wireless audio quality. Fast Charge is intended for short boosts when time is limited; use a compatible USB‑C power source.
