The market for wireless earbuds with active noise cancellation (ANC) has exploded over the past three years: according to IDC data from 2025, more than 680 million TWS (True Wireless Stereo) units were sold globally, and the share of models with ANC now represents 38% of that total — an unthinkable number in 2021, when it was less than 12%. The problem? Most consumers still associate efficient noise cancellation with prices above R$ 800 or US$ 150. QCY, a Chinese brand that has gained quiet momentum in the global market, came to question exactly this premise with the T13 ANC 2.

Officially launched in early 2026, the QCY T13 ANC 2 arrives as a direct update to the original T13 ANC — which was already a cost-benefit phenomenon — bringing a more robust audio processing chip, extended battery life, and improvements to the ANC algorithm. The target audience is crystal clear: those who work from home, commute by public transport, or simply want to isolate themselves from daily chaos without compromising their budget. But does it deliver on its promises or is it just another product that shines on paper and disappoints in practice?

I spent four weeks testing the QCY T13 ANC 2 under real conditions: on the São Paulo metro during peak hours, on video conference calls at home office, in noisy gyms, and during domestic flights. I used a calibrated sound level meter to measure noise attenuation and directly compared it with the Soundcore Liberty 4 NC and the Xiaomi Redmi Buds 5 Pro. Let’s get to what matters.

Technical Specifications

Pros and Cons

Pros:

• Genuinely effective hybrid ANC for the price range — notable attenuation of bass frequencies (airplane engine noise, air conditioning)
• Support for LC3 codec via Bluetooth LE Audio, a technology most competitors in this price range completely ignore
• Wireless charging included in a product under R$ 300 is a rarity
• Well-developed QCY App with 5-band equalizer and granular ANC level control
• Dual-device actually works — switches between smartphone and notebook without manual reconnection
• Fast charging extremely practical: 10 minutes solves low battery issues during the day
• Comfort for extended use: in-ear design with 3 silicone tip sizes and 1 foam pair included
• IPX5 certification covers gym and light rain without worry

Cons:

• ANC loses efficiency in mid and high frequencies — nearby voices leak considerably
• Microphone quality in very noisy environments still falls short of the Soundcore Liberty 4 NC
• Plastic case with finish that marks easily (visible fingerprints)
• Capacitive touch sometimes registers accidental taps when adjusting the earbud in the ear
• Transparency mode (passthrough) sounds slightly artificial, with subtle perceptible static
• No aptX or aptX HD support — LC3 compensates on compatible devices, but vanilla Android still uses SBC/AAC in most scenarios

Cost-Benefit Analysis

Here’s the central point of conversation: what does R$ 249 in 2026 actually buy?

With the T13 ANC 2, QCY delivers a set of features that, just two years ago, you’d find in products costing R$ 450 to R$ 600. Hybrid ANC — which works with microphones on both the external and internal parts of the earbud (feedforward and feedback, respectively, like two filters working in layers) — manages to attenuate 40 dB of continuous bass noise in my sound level meter tests. For reference: airplane engine rumble is around 80 dB and that’s precisely the bass range where ANC works best.

Support for the LC3 codec via Bluetooth LE Audio deserves special attention. LC3 (Low Complexity Communication Codec) is the standard codec for Bluetooth 5.2+ and offers audio quality comparable to AAC while using less than half the bandwidth — in practice, this means more stable connection and lower battery consumption. If you use an Android smartphone released in 2024 or 2025 with Bluetooth 5.2+, you’ll benefit from this advantage directly.

Wireless charging on a product in this price range is a real, not cosmetic, differentiator. In the daily routine of those working from home office — and if you’re researching productive setup configurations, check out our analysis of the Notebook for Home Office up to R$3500: Definitive Analysis 2026 — the convenience of dropping the case on a Qi charger without needing a cable makes a cumulative difference throughout the week.

The only point where cost-benefit reaches its limit is microphone quality in noisy environments. It worked well in a quiet office, but on public transport with noise above 75 dB, callers reported difficulty hearing me clearly. For remote work in a controlled environment: excellent. For calls while constantly moving: acceptable, not exceptional.

Comparison with Competitors

The T13 ANC 2 doesn’t beat the Soundcore Liberty 4 NC in any isolated technical specification — but it costs R$ 200 less. The relevant question is: does that R$ 200 difference translate to 80% better experience? In my assessment: no. The QCY easily delivers 80% of the experience for 55% of the Soundcore’s price.

Usage and Configuration Tips

Ideal Initial Setup

After pairing via Bluetooth, install the QCY App immediately (available for iOS and Android, updated in January 2026 with redesigned interface). In the app:

• Go to Equalizer and select the “Bass Boost” preset for music or “Vocal” for podcasts and calls
• In ANC Level, set it to level 2 of 3 for daily use — level 3 increases battery consumption by ~25% without proportional gains in normal environments
• Enable gaming mode only when necessary: reduces latency to ~55ms but also reduces audio quality

Common Troubleshooting

• Earbud doesn’t sync with each other after putting back in case: place both in case for 10 seconds, remove together. Solves 95% of cases reported on QCY forum
• Capacitive touch too sensitive: in the app, adjust touch sensitivity in “Touch Control Settings” — reducing to medium level eliminates most accidental taps
• Unstable connection with notebook: check if your notebook’s Bluetooth driver is updated. On Windows 11, outdated drivers cause frequent connection drops with earbuds using LE Audio
• Transparency mode with static: it’s a hardware limitation in this price range — no patch planned according to QCY communication from February 2026

Future of Technology

The QCY T13 ANC 2 represents a clear inflection point: acceptable ANC quality has completely democratized by 2026. The next step already observed in premium products — and which should reach mid-range by 2027-2028 — is personalized ANC by ear profile, where the app analyzes your ear canal anatomy via internal microphone and calibrates ANC individually. Jabra and Sony already offer versions of this in products above US$ 200.

Another relevant development is LE Audio Auracast, an extension of Bluetooth LE Audio that allows audio transmission to multiple devices simultaneously — imagine connecting your earbuds to an airport or cinema audio system. Infrastructure is still developing, but earbuds with LC3 support like the T13 ANC 2 are already technically prepared to receive this functionality via firmware update.

Final Verdict

The QCY T13 ANC 2 is not perfect — but it’s possibly the best TWS with ANC you can buy in 2026 without exceeding R$ 300. It delivers where it matters to most people: functional noise cancellation, comfortable battery life, wireless charging, and an app that respects user intelligence.

If you use earbuds mainly at home in a home office or on public transport, this product solves your problem with ease. If you live in meetings in extremely noisy environments or are a demanding audiophile, the quality delta of the Soundcore Liberty 4 NC justifies the higher price.

Overall Rating: 8.4/10

Recommended for: remote workers, students, public transport users, and those seeking functional ANC without budget compromise

Best price range: R$ 229 to R$ 269 (monitor promotions on Amazon Brasil and AliExpress — the product usually has 15-20% discount during events like Prime Day and 11.11)
