The Noise Master Buds 2 use an in-ear fit and come with wingtips included to help keep them in place during use. They are fully true wireless, meaning there are no cables or neckband involved. The earbuds carry an IPX5 rating, classifying them as water resistant and capable of handling sweat and light splashes. Stereo speakers are present, while RGB lighting, a UV light, and a display are not part of the design.
The Noise Master Buds 2 include both active noise cancellation (ANC) and passive noise reduction, offering two layers of sound isolation during use. Audio is handled by a 10 mm driver unit with a frequency range spanning 20 Hz to 20,000 Hz. Spatial audio is supported, adding a wider sound stage experience, though Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of the configuration.
The Noise Master Buds 2 offer 6 hours of battery life per charge, with the included charging case extending the total to 24 hours. The earbuds take 1.5 hours to fully charge and feature a battery level indicator so users can keep track of remaining power. The battery is rechargeable, though wireless charging and solar charging are not supported.
The Noise Master Buds 2 connect wirelessly via Bluetooth 6.1 with a maximum range of 10 meters and support fast pairing for quick device setup. Supported audio codecs include LDHC and AAC, while LDAC, aptX in all its variants (including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice), and Bluetooth LE Audio are not available. Auracast and NFC pairing are also absent. USB Type-C is present for wired charging, and the earbuds can be used fully wirelessly.
The Noise Master Buds 2 include a practical set of everyday features, starting with ambient sound mode, in/on-ear detection for auto-pausing playback, and a find device function. Multipoint connectivity supports up to two devices simultaneously, and fast charging is available for quick top-ups. The earbuds can be used as a headset and include a mute function, voice prompts, and a control panel placed on the device itself, though there is no in-line control panel. A travel bag is included in the box. Notification reading, a built-in translator, a body temperature sensor, and a camera remote shutter function are not present.
The Noise Master Buds 2 are equipped with a 6-microphone array that includes noise-canceling microphone technology, helping to reduce unwanted background sound during calls and voice input.
