The QCY MeloBuds N70 adopt an in-ear true wireless design, meaning there are no cables or cords connecting the two earbuds. They include stereo speakers but come without wingtips, a neckband, RGB lighting, a display, or a UV light. Protection against moisture is covered by an IPX5 rating, classifying them as water resistant and capable of handling sweat and minor splashes during everyday use.
The MeloBuds N70 support both active noise cancellation (ANC) and passive noise reduction, giving them two layers of isolation from ambient sound. Their frequency response spans the full standard audible range, from 20 Hz up to 20,000 Hz. Spatial audio, Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of the specification for this model.
Each earbud carries a 40 mAh rechargeable battery delivering up to 10 hours of playback, which drops to 7 hours when ANC is active. The charging case holds a 480 mAh cell, extending total listening time to 40 hours before needing a top-up. A full charge takes 1.5 hours, and a battery level indicator is included to keep track of remaining power. Wireless charging and solar charging are not supported on this model.
The MeloBuds N70 connect wirelessly via Bluetooth 6 with a maximum range of 10 meters, and support the LDAC and AAC codecs for audio transmission. The aptX family of codecs — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — is not supported, nor are LDHC, Bluetooth LE Audio, or Auracast. Fast pairing and NFC-based pairing are also absent, and the charging case connects to power via USB Type-C.
The MeloBuds N70 include an ambient sound mode for awareness of surrounding sounds, a mute function, voice prompts, and on-device touch controls. They can function as a headset for calls and support fast charging. A travel bag is included in the box. In-ear detection, a find-device feature, notification readout, a built-in translator, an in-line control panel, and a body temperature sensor are not part of this model's feature set.
The MeloBuds N70 are equipped with a total of 6 microphones, and noise cancellation is applied to the microphone input to help reduce unwanted background sound during calls and voice use.
