The QCY AilyBuds Pro Plus follow a standard earbud fit without neckband or wingtip attachments, keeping the design minimal and self-contained. Each unit weighs just 8 grams, and the setup is fully wireless with no cables connecting the two earbuds. Stereo speakers are present in both units. For durability in active use, the earbuds carry an IPX5 ingress protection rating, making them resistant to sweat during workouts or daily wear.
The AilyBuds Pro Plus use a 13 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz, spanning the full standard audible spectrum. Active noise cancellation is supported, giving users the ability to reduce ambient sound in noisy environments, though passive noise isolation is not a listed feature. The drivers do not use a neodymium magnet.
Each earbud holds a 27 mAh rechargeable battery that delivers up to 5 hours of playback, which drops to 4 hours when active noise cancellation is in use. The 350 mAh charging case extends the total battery life to 23 hours, and a full charge takes 1 hour. Wireless charging is not supported, but a battery level indicator is available to keep track of remaining charge across the earbuds and case.
The AilyBuds Pro Plus connect wirelessly over Bluetooth 5.3 with a maximum range of 10 meters and an audio latency of 80 ms. Among the supported codecs, LDAC is available for higher-resolution wireless audio transmission, while AAC, aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, aptX Voice, and LDHC are all absent. Fast pairing and NFC-based pairing are not supported, and the case charges via USB Type-C.
The AilyBuds Pro Plus include an ambient sound mode for letting in environmental audio, along with a mute function and voice prompts for hands-free feedback during use. They can function as a headset for calls, and controls are handled through a panel placed on the device rather than an in-line control on a cable. Multipoint connectivity supports up to two devices simultaneously, and fast charging is available. A travel bag is included in the box. In-ear detection, a find-device feature, notification readout, and a body temperature sensor are not part of the feature set.
The AilyBuds Pro Plus 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 interactions.
