The Nothing Ear 3 adopt an in-ear fit and a fully true wireless design with no cables or neckband, keeping things minimal and unencumbered. Each earbud weighs just 10.4 grams and includes stereo speaker output, while wingtips are not part of the package. The earbuds carry an IP54 rating, making them resistant to water and dust ingress — a practical consideration for daily use. RGB lighting, a UV light, and an onboard display are absent from the design, reflecting a clean, understated aesthetic.
The Nothing Ear 3 are equipped with a 12 mm driver unit and cover a frequency range spanning 20 Hz to 40,000 Hz, allowing for a broad sonic bandwidth. Both active noise cancellation and passive noise reduction are supported, giving users two layers of isolation from ambient sound. Spatial audio is also on board, adding a dimensional quality to playback. Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of the sound hardware configuration.
The Nothing Ear 3 earbuds carry a 55 mAh rechargeable battery that delivers up to 10 hours of playback, which drops to 5.5 hours when active noise cancellation is enabled. The accompanying charging case holds a 500 mAh battery and extends the total available listening time to 32 hours. A full charge takes 1.2 hours, and both wireless charging and a battery level indicator are supported, making it straightforward to monitor and replenish power. Solar charging is not available on this model.
The Nothing Ear 3 connect wirelessly via Bluetooth 5.4 with a maximum range of 10 metres, and support fast pairing for a quicker setup experience. Supported audio codecs include LDAC and AAC, while aptX in all its variants — including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice — are not available. Bluetooth LE Audio, Auracast, LDHC, and NFC pairing are likewise absent. The charging case uses USB Type-C for wired charging, rounding out the connectivity options on this model.
The Nothing Ear 3 include a practical set of features for daily use, among them ambient sound mode, in/on-ear detection for automatic playback pausing, and a find device function. Multipoint connectivity supports simultaneous pairing with two devices, and the earbuds can function as a headset with a mute function available during calls. Fast charging is supported, and voice prompts are present for audio feedback. Device-side touch controls are available, though an in-line control panel is not included. A travel bag comes in the box, while notification reading, a body temperature sensor, and a built-in camera remote are not part of the feature set.
The Nothing Ear 3 feature a six-microphone array paired with noise-canceling microphone technology, aimed at reducing unwanted background sound during calls and voice input.
