The QCY Melobuds N50 follow a true wireless, in-ear design with no cables or neckband, keeping the build minimal and unencumbered. Each earbud weighs just 8 g and sits directly in the ear without wingtip attachments, while stereo speakers deliver audio to both ears independently. The earbuds carry an IPX5 ingress protection rating, meaning they can handle water jets from any direction — suitable for workouts or light rain exposure. There is no RGB lighting, no UV light, and no display on either the earbuds or the case, reflecting a straightforward, understated physical design.
The Melobuds N50 include both active noise cancellation (ANC) and passive noise reduction, giving listeners two layers of isolation from ambient sound. Audio is handled by a 12 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz. The earbuds do not feature a neodymium magnet, and there is no support for spatial audio, Dolby Atmos, or Dirac Virtuo processing.
Each earbud houses a 35 mAh rechargeable battery rated for 6 hours of playback, which drops to 4 hours when ANC is active; the 380 mAh charging case contributes an additional 22 hours, bringing the combined total to 28 hours without ANC. A full charge takes 1.5 hours, and a battery level indicator lets users monitor remaining capacity. The earbuds do not support wireless charging or solar charging, so power is replenished through a wired connection only.
The Melobuds N50 connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m and a stated audio latency of 68 ms. The earbuds do not support fast pairing, NFC pairing, AAC, LDAC, LDHC, Auracast, or any variant of aptX — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — and Bluetooth LE Audio is also absent. USB Type-C is present for wired charging, though it plays no role in audio transmission given the fully wireless operation.
The Melobuds N50 support multipoint connectivity for up to two devices simultaneously and can function as a headset for calls, with a mute function available during use. An ambient sound mode lets environmental audio through when needed, and controls are handled via a panel on the earbuds themselves rather than an in-line remote. Fast charging is supported, and voice prompts provide audio feedback for various functions. A travel bag is included in the box. The earbuds do not offer in/on-ear detection, a find-device feature, notification readout, a body temperature sensor, or a camera remote shutter function.
The Melobuds N50 feature a six-microphone array with noise-canceling microphone technology, aimed at reducing background noise during calls and voice input.
