QCY MeloBuds N70 Complete Review: Is It Worth Every Penny?
The true wireless stereo (TWS) earbud market has exploded impressively over the last few years. In 2026, IDC estimates that over 600 million TWS earbud units will be sold globally per year. The problem? Most consumers still face the same age-old dilemma: pay premium prices for brands like Sony and Apple, or take a chance on generic products that disappoint after two months. This is precisely the gap that QCY, a Chinese manufacturer with nearly a decade of experience in the affordable audio segment, is trying to fill with the MeloBuds N70.
The N70 arrives promising active noise cancellation (ANC — a “invisible shield” that captures external sounds via microphone and emits inverse sound waves to neutralize them), a 12mm driver with titanium membrane, and up to 43 hours of combined battery life. All of this at a price point ranging between R$ 180 and R$ 250 in Brazil in 2026. On paper, it sounds almost too good to be true. But does reality confirm the marketing?
I spent three weeks testing the QCY MeloBuds N70 in varied situations: gym, home office with Google Meet calls, subway during rush hour, domestic flights, and long streaming sessions. I also ran technical latency tests with specialized apps and compared ANC performance with other models in the same price range. I’ll tell you everything honestly — the good, the bad, and what nobody tells you before buying.

Pros and Cons
Pros:
- Surprisingly effective ANC for the price range, especially against constant noise (ventilation, subway)
- Comfortable and lightweight design; no pain even after 4 continuous hours of use
- Excellent battery autonomy — 8 hours with ANC off is competitive even with premium models
- Multipoint connectivity works well in practice (I could switch between notebook and phone without manual reconnection)
- QCY app with 5-band equalizer, ANC adjustment, and customizable modes
- IPX5 ensures worry-free use at the gym and in light rain
- USB-C is very welcome (goodbye, micro-USB!)
- ~65ms latency in game mode is acceptable for casual mobile gaming
Cons:
- Codec limited to SBC and AAC — no aptX, LDAC, or aptX Adaptive, limiting audio quality potential with lossless streaming
- ANC loses efficiency against irregular and high-pitched noise (conversations, isolated car horns)
- Microphone for calls is mediocre — works well in quiet environments but struggles in noisy locations
- Bass slightly exaggerated in default profile (“V-shaped EQ”), may bother those preferring neutral sound
- Plastic case scratches easily
- No wireless charging
- Touch controls are overly sensitive — accidental activations are frequent
Cost-Benefit Analysis
Let’s be direct: the QCY MeloBuds N70 is an honest product. And in a market full of dishonesty, that’s already a lot.
For an average price of R$ 200, you’re buying earbuds with functional ANC, robust battery, Bluetooth 5.3 with multipoint, and an app that actually serves a purpose. For context, the Sony WF-1000XM5 — still considered the ANC reference — costs between R$ 1,200 and R$ 1,500 in Brazil in 2026. Of course, the comparison isn’t fair in absolute terms, but it helps understand where the N70 fits.
The main Achilles’ heel is the codec limitation. Without LDAC or aptX HD, the N70 can’t transmit high-resolution audio efficiently. If you subscribe to Tidal HiFi or Amazon Music Ultra HD expecting to hear the difference, you’ll be disappointed — the signal will be converted to AAC or SBC, compressing quality. Think of it like trying to watch 4K HDR on a monitor that only displays 1080p: the content exists, but the hardware doesn’t deliver everything.
On the other hand, for the use 90% of people make — Spotify, podcasts, YouTube, calls, and gym sessions — the N70 performs very well. The app’s equalizer can correct the default profile’s bass excess, and the sound becomes much more balanced. With the custom profile I configured (2dB reduction in 100-200Hz frequencies and slight 4kHz boost), the result was quite pleasant for rock and jazz.
Comparison with Competitors
| Model | Price (BR, 2026) | ANC | Codecs | Total Battery | Multipoint | IP |
|---|---|---|---|---|---|---|
| QCY MeloBuds N70 | R$ 180–250 | Yes (-35dB) | SBC, AAC | ~43h | Yes | IPX5 |
| Anker Soundcore P40i | R$ 220–280 | Yes (-50dB*) | SBC, AAC, LDAC | ~60h | Yes | IPX5 |
| JBL Tune 230NC TWS | R$ 250–320 | Yes | SBC, AAC | ~40h | No | IPX4 |
| Xiaomi Redmi Buds 6 Active | R$ 130–180 | Yes (basic) | SBC, AAC | ~35h | No | IP54 |
| Nothing Ear (a) | R$ 380–450 | Yes | SBC, AAC, LDAC | ~42h | Yes | IP54 |
The Anker P40i claims -50dB, but in real tests performs similarly to the N70 against variable frequency noise.
The N70 loses badly to the Anker Soundcore P40i on paper — especially for having LDAC — but wins in design and comfort. Against the Xiaomi Redmi Buds 6 Active, the N70 has a clear advantage in ANC and overall sound quality. The Nothing Ear (a) is the natural upgrade for those wanting to step up without breaking the bank.
Usage and Setup Tips
Recommended Initial Setup
- Download the QCY App (available for Android and iOS) before anything else. My unit’s firmware was outdated; the update took 4 minutes and improved Bluetooth stability.
- In the equalizer, try the “Vocal” preset for calls and podcasts, and create a custom profile for music by reducing bass.
- Configure multipoint early on: go to Settings > Connection > Two Devices. This prevents the frustration of manual reconnection when switching between phone and notebook.
Common Troubleshooting
- Earbud randomly disconnecting? Factory reset solves it in most cases: place both in case, press the rear button for 10 seconds until LED flashes three times in white.
- Accidental touch activations? In the app, reduce touch sensitivity or reassign functions. I disabled the double-tap that paused music and life got much better.
- ANC creating uncomfortable ear pressure? Try different silicone earbud sizes. A poor fit sabotages both ANC and passive isolation. The N70 comes with four sizes (S, M, L, and XL).
- High latency in games? Make sure Game Mode is active in the app. It reduces latency to ~65ms at the cost of slight audio quality reduction.
The Future of Technology
The N70 is a snapshot of where the affordable earbud segment arrived in 2026 — and also makes clear where there’s still room to evolve. The absence of LDAC and aptX HD in an increasingly competitive price range should be addressed in future generations. QCY already has models with LDAC (like the T21S), so it’s just a matter of time before this comes down to more accessible lines.
Another point to watch: AI-powered ANC. Premium models already use dedicated chips that identify the type of noise and adjust cancellation in real-time. This technology is expected to reach the mid-range segment by 2027-2028. Also keep an eye on Bluetooth LE Audio (LC3 codec), which promises better energy efficiency and superior audio quality — the N70’s Bluetooth 5.3 is already compatible with the architecture, but it depends on future implementation.
If you’re building a complete home office setup, it’s also worth checking out the Best USB-C Hub with HDMI for Notebook in 2026 to complement your workstation with the N70 as your primary call earbud.
Final Verdict

The QCY MeloBuds N70 isn’t perfect — no product at this price point is. But it does things right consistently: functional ANC, honest battery life, real comfort, and an app that adds value. The gaps — lack of high-resolution codecs, mediocre microphone in noisy environments, and case that scratches easily — are understandable given the price but need to be on your radar before purchase.
If your use is mostly Spotify, podcasts, gym, and home office calls, the N70 will serve you very well and leave money in your pocket. If you’re an audiophile who subscribes to lossless services and demands maximum sound fidelity, look at the Nothing Ear (a) or wait a bit longer.
Overall Rating: 8.2/10
Recommended for: Casual to intermediate users who want real ANC, good battery life, and modern connectivity without paying over R$ 300
Best price range: R$ 180 – R$ 220 (above that, the Anker P40i starts making more sense)
