Description
Active noise cancelling has become a specification that most brands quote and few measure. The number that matters is not the depth of cancellation in a quiet room, which is easy, but how fast the system adapts when the noise floor changes: a train door opening, a cafe filling up, wind hitting a microphone on a bike. Adaptive ANC is the difference between a fixed filter and a system that keeps re-measuring the room.
The QCY MeloBuds Pro quotes up to 46dB of cancellation from a hybrid adaptive system that samples ambient noise and adjusts the filter continuously, built on Bluetooth 5.3 with LDAC support for higher bitrate streaming on Android handsets that support it. The driver is 12 mm, which is large for this class and is where the low end comes from, and the battery is 350mAh in the case with a total playback figure of up to 34 hours including case recharges, which works out to about four full charges of the earbuds. The earbuds themselves measure 20.7 x 33.6 x 23.4 mm and the case 56.3 x 51.1 x 28 mm, so the case stays in a jeans pocket, and IPX5 covers sweat and rain rather than submersion.
The rest of the specification is aimed at the parts of the day where earbuds get used rather than demonstrated. Dual connection lets a laptop and a phone stay paired at once, so a call arriving mid-session does not require digging through Bluetooth settings. The microphone array uses an AI algorithm to separate voice from background, which matters more on video calls than on music. A Type-C port means one cable in the bag covers the earbuds, the phone and the laptop, and LDAC is available when the source supports it rather than being the only codec on offer.
The quiet is adjustable. That is the whole point of measuring the room.
What Sets It Apart
-
Up to 46dB adaptive ANC
A hybrid system that samples ambient noise and re-tunes the filter continuously, rather than applying one fixed profile to every environment. -
12 mm drivers
Large for the class, and the reason the low end holds together at moderate volume without the midrange collapsing. -
LDAC codec support
Higher bitrate streaming on Android sources that support LDAC, with standard codecs available for everything else. -
34 hours total playback
Up to 34 hours including case recharges from a 350mAh case, which is roughly four full charges of the earbuds. -
Dual connection
Two devices paired at once, so a call can arrive without unpairing the laptop you were working on. -
IPX5 and USB Type-C
Sweat and rain resistant, charged from the same Type-C cable as the rest of your kit.

Where It Belongs
Commuters get the most obvious use: adaptive cancellation that handles a platform, a carriage and a walk at the other end without resetting a mode. Remote workers use dual connection to keep a laptop and phone live at once, with the microphone array handling calls in rooms that are not treated for audio. Runners and cyclists get IPX5 for sweat and weather and a sealed in-ear fit that does not need to be pushed back in every few minutes. Travellers get 34 hours of total playback from a case that fits a pocket, which covers a long haul and the transfer at the other end.
Questions Buyers Ask Before Ordering
Q: Does the 46dB figure apply to all noise types?
It is the peak cancellation the system quotes, and real world performance varies with frequency. Low frequency noise such as engines and air conditioning is where adaptive ANC is strongest; sudden high frequency sounds are reduced rather than removed.
Q: Which phones support LDAC?
LDAC is available on many Android handsets, with support varying by model and by the streaming app's settings. Apple devices use AAC, and the earbuds fall back to standard codecs automatically.
Q: How long does the battery actually last?
Up to 34 hours total including case recharges, from a 350mAh case that provides about four full charges of the earbuds. ANC at maximum depth reduces earbud runtime, as it does on any active system.
Q: Can I connect a laptop and a phone at the same time?
Yes. Dual connection keeps two devices paired, so a call can arrive while the laptop is still connected. Both devices need to support standard Bluetooth audio.
Q: Are they waterproof?
IPX5 covers sweat and rain. They are not designed for swimming or submersion, and charging contacts should be dried before the earbuds go back in the case.
Q: Do they work for calls in a noisy room?
The microphone array uses an AI algorithm to separate voice from background noise, which is what the feature is for. Very loud environments still degrade any in-ear microphone, so a quiet corner helps.
