The QCY MeloBuds N70 combine an ambitious feature set—adaptive ANC, LDAC audio, wireless charging and long battery life—in compact true wireless earbuds. Here is what the verified specifications promise, where the trade-offs lie, and who should consider them.
On paper, the N70 are an attractive option for commuters, remote workers and frequent listeners who want strong features without immediately moving to premium-priced earbuds. Treat the 56 dB ANC figure as a manufacturer claim, not a guarantee of uniform real-world isolation.

QCY MeloBuds N70: What You Should Know
The QCY MeloBuds N70 (also identified as HT18) are in-ear true wireless earbuds with Bluetooth 6.0, a dual-driver acoustic design, adaptive active noise cancellation and LDAC codec support. QCY lists a dynamic driver paired with a MEMS tweeter, an arrangement intended to distribute low- and high-frequency reproduction between two driver types. The manufacturer also specifies dual-device connectivity and personalized equalization through its companion software.
The key buying distinction is how to interpret the headline figures. QCY advertises adaptive noise reduction of up to 56 dB, but actual attenuation varies with fit, frequency and surroundings. The 50-hour battery figure refers to total listening time including the charging case with ANC switched off. With ANC on, the stated total drops to 35 hours. This is a specification-based guide, not a claim that TwistersMix physically tested the earbuds.

Adaptive ANC: Useful for Focus, With Real Limits
QCY markets its PureSilenz adaptive ANC at up to 56 dB across a wide frequency range. Active cancellation can be valuable against predictable background noise such as ventilation and public transport, while the silicone ear tips also provide passive isolation. However, a maximum laboratory figure does not predict every everyday situation. Voices, sudden impacts and wind may remain audible; a secure seal is essential. If you frequently work in a café, train or shared office, ANC is a meaningful reason to evaluate this model—but not an assurance of total silence.
Dual Drivers and LDAC: Who Actually Benefits?
Each earbud combines a dynamic driver with a MEMS tweeter, according to QCY. The earbuds support LDAC, a Bluetooth codec that can carry higher-bitrate audio when the phone, operating system and playback configuration support it. Android users with compatible devices may find this particularly relevant; iPhone users should not expect LDAC support from their phones. Higher codec bandwidth does not automatically mean better sound to every listener, and fit, recording quality and EQ remain important. QCY includes an app-based hearing test for a personalized EQ profile.
Battery Life: Understand the 50-Hour Claim
The company rates the N70 at up to 10 hours on a single charge with ANC disabled, or a combined 50 hours using the charging case. Turning ANC on lowers the stated figures to up to 7 hours per charge and 35 hours total. Runtime also changes with volume, codec, call usage and environmental conditions; these are manufacturer figures rather than independently measured results. Both USB-C charging and wireless charging are supported, an advantage if your desk already has a compatible charging pad.

QCY describes a three-microphone system with AI-assisted call processing and supports dual-device connectivity. That matters if you switch frequently between a phone and a computer during a workday. Microphone clarity still depends on wind and background noise, so do not assume professional headset-level performance in every setting. Bluetooth 6.0 support is useful on the specification sheet, but practical stability also depends on the host device and radio environment. Verify the seller’s exact variant before ordering.
Comfort, Water Resistance and Buyer Checks
Five ear-tip sizes (XS through XL) increase your chances of achieving a comfortable seal, important both for bass response and ANC. The IPX5 rating covers exposure such as sweat and splashes; it does not make these earbuds suitable for swimming or immersion. Before buying on AliExpress, check seller history, the chosen color and variant, shipping destination, taxes, return policy and whether the listing specifically names QCY MeloBuds N70 / HT18. A listing that merely looks similar is not a substitute for exact-model verification.
Pros and Cons
- LDAC plus dual-driver acoustic system
- Adaptive ANC and five ear-tip sizes
- USB-C and wireless charging
- Up to 50 hours of case-supported listening with ANC off
- Maximum ANC reduction is a laboratory-style claim, not a guaranteed everyday result
- Battery life falls materially when ANC is enabled
- No immersion protection; LDAC depends on the source device
Who Should Buy It?
Consider the QCY MeloBuds N70 if your daily routine involves public transport, video calls, podcasts and music, and you value a combination of noise cancellation, adaptable fit and long battery life. They make particular sense for listeners with compatible Android devices who want to try LDAC. Before choosing them over a competing model, compare the live AliExpress price with local return options and independent microphone/ANC testing. For swimmers, specialist workplace headsets or buyers demanding verified premium ANC performance, a different product category may be the more rational choice.
Frequently Asked Questions
Do the QCY MeloBuds N70 support LDAC on iPhone?
The earbuds support LDAC, but iPhones do not currently offer LDAC Bluetooth playback. On an iPhone you can still pair the earbuds using a compatible codec supported by both devices.
How long does the battery last with noise cancellation enabled?
QCY states up to 7 hours on one charge and 35 hours including the case with ANC on. With ANC off, those stated maximums increase to 10 and 50 hours respectively. Real runtime varies.
Can I wear them in the rain or shower?
They carry an IPX5 water-resistance rating, which is intended for splashes and sweat, not immersion. Avoid showering or swimming with them and keep the charging case dry.
Do the earbuds offer wireless charging and connection to two devices?
Yes. QCY lists wireless charging and dual-device connectivity as features of the MeloBuds N70. Check your particular seller listing and device compatibility before purchasing.
