QCY MeloBuds N70: Complete Review for the Brazilian Market
QCY is a Chinese brand that has already gained ground in Brazil with affordable entry-level earbuds, but the MeloBuds N70 arrives with a slightly more ambitious proposal: active noise cancellation (ANC, which uses microphones to capture and neutralize ambient sounds before they reach the ear), larger drivers and extended battery life. The product is positioned in the intermediate range of the TWS (True Wireless Stereo, completely wireless earbuds without cables) market, competing with established competitors such as JBL and Sony in this same price category.
The short answer: for those looking for functional ANC, good battery and price below R$ 300, the N70 is an option that deserves serious attention. If you already have a budget close to R$ 500 or more, the jump in quality to premium brands starts to make more sense. The product fits better with the profile of those who use the earbuds on the home-to-work commute, in a home office or want an upgrade over entry-level earbuds without spending the equivalent of a top-of-the-line model.

Design, Comfort and Ergonomics
The N70 adopts an in-ear format with interchangeable silicone tips, which is already standard in the category. The short stem resembles the AirPods design, but with a slightly more robust body. QCY typically uses matte plastic that hides fingerprints well, something that glossy earbuds in the same price range cannot achieve.
The silicone tip fit ensures reasonable passive isolation even before turning on ANC. For those with smaller ears, it’s worth testing all included tips before concluding that the earbuds won’t fit. The case is compact in size and opens with a hinge that transmits a sense of solidity above what you’d expect for the price.
The IPX5 rating means the earbuds can withstand water jets from any direction, which covers heavy perspiration and moderate rain, but not immersion. It’s sufficient for gym use and urban environments.
Sound Quality and Noise Cancellation
According to the manufacturer, the 10 mm driver was calibrated to provide more bass presence without muffling midrange frequencies. In day-to-day practice, earbuds in this range with a 10 mm driver tend to sound good for pop, hip-hop and podcasts, but can sound a bit thick in the bass for those who prefer a more neutral or analytical sound. If you’re a critical listener of classical music or jazz, it’s worth getting a listen before buying.
QCY’s ANC in previous models worked well for continuous noise, such as ventilation and public transport engines, but performed less well against voices and abrupt sounds. The N70 promises improvements in this area, but the exact attenuation level in decibels has not been publicly disclosed in detail. The recommendation is to distrust any advertising that cites a dB number without specifying the measurement methodology.
The transparency mode (passthrough) captures external audio through microphones and passes it to the ear, useful for crossing a street without removing the earbuds. The quality of this mode varies greatly between brands: in entry-level QCY models it sounds somewhat artificial, and the N70 should improve this with the number of microphones, but there is no independent published data yet to confirm.
Battery and Connectivity in Practice
Nine hours per charge on the earbuds, reaching 36 hours with the case, places the N70 among the most durable in the category. These numbers are always measured without ANC active and with moderate volume by the manufacturer. In real life with ANC on, expect somewhere between 6 and 7 hours per charge on the earbuds, which is still competitive.
Charging via USB-C is standard and welcome. Bluetooth 5.3 offers superior stability to previous protocol versions and lower latency, which helps with calls and video calls, but doesn’t replace a low-latency audio codec for those who want to use the earbuds for gaming on their cell phone.
The QCY App (available free for Android and iOS) allows you to adjust the equalizer, switch ANC modes and update firmware. It’s a real differentiator compared to competitors in the same range that don’t offer an app, even if the interface isn’t as refined as Sony’s or JBL’s.
QCY MeloBuds N70 in Brazil: Availability, Homologation and Warranty
This is a critical point for any electronic purchase. QCY has official distribution in Brazil through partner resellers and platforms such as Shopee, Mercado Livre and Amazon.com.br. The status of Anatel homologation (mandatory certification for radio frequency devices sold legally in the country) should be verified directly on the product label or on the Anatel website, as recently launched models may have homologation process underway.
Buying from a reseller without an invoice compromises access to warranty. QCY offers 12-month warranty for products purchased in Brazil through authorized channels, in accordance with the Consumer Protection Code. In direct imports via sites like AliExpress, warranty is negotiated with the seller, which complicates a potential exchange. If you’re deciding between buying locally with invoice or importing for 20% less, consider the cost of a problem without support.
The price range in Brazil hovers around R$ 200 to R$ 280 depending on the channel and promotion, with seasonal variations. In the US, the product was launched in the US$ 40 to US$ 50 range, which explains the competitiveness even after import taxes.

Competitors and Alternatives in Brazil
| Model | Price Range (BR) | ANC | Total Battery Life | App |
|---|---|---|---|---|
| QCY MeloBuds N70 | R$ 200 to R$ 280 | Yes | Up to 36 hours | Yes |
| JBL Tune 230NC TWS | R$ 280 to R$ 380 | Yes | Up to 40 hours | Yes |
| Samsung Galaxy Buds FE | R$ 300 to R$ 400 | Yes | Up to 30 hours | Yes |

| Sony WF-C510 | R$ 400 to R$ 500 | No | Up to 22 hours | Yes |
> Prices collected from national sales channels and subject to change. The Sony WF-C510 was included as a consolidated alternative without ANC, but with recognized sound quality. When considering whether the Galaxy S25 FE is worth buying in 2026, it’s worth remembering that the Samsung ecosystem favors Galaxy Buds with exclusive integration features.
The Xiaomi Redmi Buds 5 Pro is the most direct competitor: similar price, ANC present and functional app. The main difference lies in the perceived build quality and local support, where QCY tends to have less physical technical assistance in Brazil.
Frequently Asked Questions About the QCY MeloBuds N70
Does the N70 work well with iPhone?
Yes, Bluetooth 5.3 is compatible with iOS without any additional configuration needed. The QCY App is also available on the App Store. The only point of attention is that the AAC codec (preferred by iPhone) needs to be confirmed in the technical sheet of the model before purchase.
Is it possible to use just one earbud at a time?
Most current TWS earbuds support mono use, and QCY indicates this functionality in its recent models. Check the product manual to see if there are any limitations (such as ANC or controls) in mono mode.
Does the case charge wirelessly?
QCY has not officially confirmed wireless charging on the N70 in publicly available materials so far. Before buying expecting this feature, check the physical packaging or the description from an authorized reseller.
Does the earbud have audio lag for games and videos?
Bluetooth earbuds have inherent latency in the protocol. Bluetooth 5.3 reduces this lag, but for competitive games the delay is still noticeable. For videos on mobile, most operating systems do automatic compensation that solves the problem in practice.
Is the QCY MeloBuds N70 Worth It?

For those who want functional ANC, good battery and a decent app without exceeding R$ 280, the N70 delivers on an honest proposal. QCY has a track record of good value for money, and the N70 is no exception to that logic. Don’t expect the sound precision of a Sony or the ecosystem integration of a Samsung, but for daily use on public transport, home office and gym, the earbuds deliver on what they promise.
If your budget allows for R$ 350 or more, it’s worth comparing with the JBL Tune 230NC TWS, which has more accessible technical support in Brazil and a more recognized brand for future resale. For those evaluating a complete productivity ecosystem, it may also be useful to look at other technology categories, such as the best laptops for programming up to R$ 5,000 in 2026, especially if you work from home and want to build a complete setup.
Recommended for: those looking for ANC in earbuds below R$ 280, public transport users, home office workers who need to block noise without spending on premium brands.
Price Range: R$ 200 to R$ 280 in Brazil (US$ 40 to US$ 50 in the US at launch); confirm the updated value at the point of sale before buying.
