The Noise Buds R1 feature an in-ear fit and a fully true wireless design, meaning there are no cables or cords involved. They are not neckband-style earbuds and do not include wingtips, keeping the form factor compact and straightforward. Stereo speakers are built in, and the earbuds carry an IPX5 ingress protection rating, making them resistant to sweat during use.
The Noise Buds R1 rely on passive noise reduction to limit ambient sound, as they do not include active noise cancellation (ANC). Audio is handled by an 11 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz. The earbuds do not use a neodymium magnet in their driver configuration.
The Noise Buds R1 are equipped with a rechargeable battery that delivers up to 8 hours of playback, with the charging case extending the total available power to 32 hours. A full charge takes approximately 1.5 hours, and a battery level indicator is included to keep track of remaining power. Wireless charging is not supported, so the earbuds rely on a wired connection for recharging.
The Noise Buds R1 connect wirelessly via Bluetooth 5.3 and support the AAC codec, while higher-end audio formats such as LDAC, LDHC, aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice are not included. The maximum Bluetooth range reaches 10 m, and audio latency is quoted at 40 ms. Fast pairing and NFC-based pairing are not available. For wired charging and data purposes, the earbuds use a USB Type-C connection.
The Noise Buds R1 support fast charging and can function as a headset, with a mute function and voice prompts built in for added convenience during calls or general use. Controls are handled through an on-device panel rather than an in-line control panel on a cable. A travel bag is included in the box. The earbuds do not offer ambient sound mode, in/on-ear detection, a find-device feature, or a body temperature sensor.
The Noise Buds R1 include a four-microphone setup with noise-canceling microphone capability, helping to reduce unwanted background sound during calls and voice input.
