QCY MeloBuds N70: Worth Every Penny in 2026?

In 2026, the true wireless stereo (TWS) earbud market surpassed 400 million units sold globally, with nearly 60% of sales concentrated in the under $80 price range. This says a lot about where the real battle is happening. It’s not between AirPods Pro and Sony WF-1000XM6 — it’s between dozens of Chinese brands that learned, in record time, to deliver mid-level quality at prices that seem like typing errors.

The problem that has always existed in this segment is simple: how do you know who is actually delivering value and who is just packaging mediocre hardware in a pretty box with inflated specifications? The QCY MeloBuds N70 arrives promising efficient ANC (active noise cancellation), high-quality drivers, and battery life for days of use — all for around $45 / R$ 230 in the Brazilian market in 2026. Sounds too good to be true? Maybe not.

I spent three weeks with the N70 in my daily routine: on the São Paulo subway, on work calls, at the gym, on domestic flights, and long study sessions. I tested latency with mobile games, evaluated the microphone in noisy environments, and stressed the battery to its limits. Here’s everything you need to know before clicking buy.

Technical Specifications

Pros and Cons

Pros:

• Surprisingly effective ANC for the price range, attenuating continuous noise like air conditioning and motors well
• Bluetooth 5.4 ensures more stable connection and faster reconnection compared to previous generation
• Total 28-hour battery is generous — allows 3 to 4 days without thinking about charging
• Game mode with ~55ms latency is functional for most mobile titles
• Compact and lightweight case, easy to carry in pants pocket
• QCY app offers customizable 10-band EQ, which is rare in this price range
• Good passive comfort, with three earpiece sizes included
• Decent microphone for calls in controlled environments

Cons:

• Absence of aptX or LDAC codec limits sound quality ceiling for demanding users
• ANC loses effectiveness against high-frequency noise and nearby voices
• Touch controls sometimes register accidental touches when repositioning the earbud
• Transparency mode (amplifying ambient sound) sounds artificial, with slight perceptible hiss
• App not available in Portuguese with unintuitive interface
• No wireless charging in case

Cost-Benefit Analysis

Let’s be direct: the QCY N70 doesn’t compete with Sony WF-1000XM6 or AirPods Pro 3. It competes with Xiaomi Redmi Buds 6, EarFun Air Pro 4, and TOZO Golden X1 — and in that fight, it does very well.

The financial equation is clear. An earbud with functional ANC, Bluetooth 5.4, 28-hour battery, and 10-band EQ app for R$ 230 would be unthinkable in 2022. In 2026, that’s exactly what QCY is delivering, thanks to the maturation of low-cost audio processing chips — mainly Airoha and BES (Bestechnic) chips, which equip much of today’s available entry-to-mid TWS.

The point where value-for-money may seem less attractive is if you’re a casual audiophile using high-quality streaming services like Tidal or Apple Music Lossless. Without Adaptive aptX or LDAC, the N70 is limited to SBC and AAC — codecs that compress audio more before transmitting via Bluetooth. For most people, this is imperceptible. For those with trained ears or using premium headphones at work, it may be a limitation.

For the target audience — students, professionals working from home, public transportation users, and people who simply want a functional earbud without spending much — the N70 delivers consistently. It’s not the perfect earbud, but it’s hard to find something better at this price in 2026.

Competitor Comparison

The EarFun Air Pro 4 is the only option here that supports aptX and wireless charging, and for about R$ 50 more it may make sense for more demanding users. The TOZO Golden X1 has an advantage in water resistance (IPX6) and wireless charging, but loses badly in latency for gaming.

The QCY N70 stands out for its combination of the latest Bluetooth 5.4, 10-band EQ, and competitive game mode. For those prioritizing mobile gaming and connection stability, it’s the best value-for-money on the list.

Usage and Configuration Tips

Configure the EQ from day one

The N70’s default sound profile is slightly V-shaped — highs and lows slightly elevated, midrange recessed. Works well for pop and electronic, but sounds tiring on podcasts and calls. In the QCY app, try reducing 8kHz and 10kHz frequencies by 2dB and slightly boosting 2kHz for voice. It makes a perceptible difference.

Adjust ANC based on environment

The N70 offers three ANC levels via app or triple-tap on the left earbud. On public transportation, use maximum level. In office environments, medium level is sufficient and saves battery — ANC is the function that drains the most energy in this earbud, reducing autonomy from 7h to about 5h at maximum level.

Common troubleshooting

• Earbud won’t connect after update: Reset the pair by placing both in the case, pressing the internal button for 10 seconds until the lights flash red three times. This restores factory settings.
• Frequent accidental touch: Go to the app and increase minimum touch control sensitivity. This reduces involuntary registrations without eliminating intentional gestures.
• Microphone with too much echo for listeners: Enable “Voice Enhancement” mode in the app — it applies more aggressive echo suppression, especially useful in Google Meet or Teams meetings.
• Earbud desynchronization: Remove the device from your phone’s Bluetooth panel, place the earbuds in the case, reconnect. Usually resolves 100% of the time.

Battery tip

Don’t let the earbud battery reach 0% before charging. The battery chemistry in modern TWS earbuds prefers frequent partial charges. Place in case when reaching 20% — this prolongs battery cell lifespan.

Future of Technology

The entry-to-mid TWS segment in 2026 is undergoing an interesting transition. Next-generation Airoha chips (1570 series and above) and new MediaTek chips focused on audio begin to bring support for LE Audio — the new Bluetooth standard based on LC3 codec, which promises superior quality with less energy consumption. This means that in 12 to 18 months, earbuds in this price range may support simultaneous audio transmission to multiple devices (Auracast) and dramatically better call quality.

ANC is also evolving. The trend for 2027 is using machine learning embedded in audio chips themselves to adapt noise cancellation in real time to the user’s ear profile — something that currently only exists in earbuds over R$ 1,000. QCY, like other brands in the Xiaomi-adjacent ecosystem, has a history of bringing these innovations to accessible price ranges with 12 to 18 months lag compared to the top of the line.

The N70, therefore, represents well where the market is now. Not where it will be in 2028 — but that’s fair for a product at this price.

Final Verdict

The QCY MeloBuds N70 is exactly the type of product that makes me love covering affordable technology: a gadget that doesn’t do anything extraordinary, but does everything it promises competently and consistently. The ANC works for real in everyday use, the battery holds up, Bluetooth 5.4 is stable, and the app with 10-band EQ is a bonus that earbuds three times more expensive don’t always offer.

If you’re looking for the “perfect” earbud for musicians, producers, or audiophiles, keep looking. But if you want a reliable TWS for daily use without compromising your budget, the N70 is one of the most solid choices on the market in 2026.

Overall Rating: 8.2/10

Recommended for: Students, professionals working from home, public transportation users, casual mobile gamers, and anyone who wants functional ANC without spending over R$ 300

Best price range: R$ 200 to R$ 250 — above that, the EarFun Air Pro 4 starts to make more sense
