Score: 87/100
Tozo NC20 with ANC
Score: 88/100Rankings
The TOZO NC20 combines hybrid adaptive ANC, LDAC Hi-Res audio, and an ultra-light 3.7 g earbud design with up to 80 hours of total battery life. High-resolution streaming can significantly drain the battery and the companion app may be finicky. Targeted at travelers and audiophiles who value noise cancellation and high-resolution sound in a lightweight package.
OnePlus Buds 4 are mid-range true-wireless earbuds with a coaxial dual-driver system, hybrid ANC up to 55 dB, and LHDC 5.0 high-resolution audio support. They lack wireless charging and have a bulkier case, and Bluetooth range is limited to about 10 m. They fit users looking for strong ANC, long battery life, and hi-res audio on a budget.

Professional reviewers consider the OnePlus Buds 4 a strong mid-range offering, praising its deep hybrid ANC, long battery life, and LHDC 5.0 hi-res audio, while noting the missing wireless charging and modest IP ratings as minor drawbacks.
Everyday users commend the comfort, effective noise cancellation, and subtle Storm Gray design, but express concerns about the bulkier charging case, lack of wireless charging, and limited long-term feedback due to the product's recent launch.
“Excellent ANC performance (84% noise reduction, 40 dB across frequencies, on par with premium models).”
“Comfortable lightweight design (4.7 g per bud, wearable for hours).”
“amazing with excellent clarity”
Professional reviewers commend the NC20 for delivering studio-grade sound with crisp highs, deep bass, and a DLC diaphragm that enhances high-frequency detail. The hybrid adaptive ANC is praised for its real-time responsiveness, while the lightweight, ergonomic build and IPX8 waterproofing earn marks for comfort and durability. Bluetooth 5.4 multipoint connectivity and six-mic AI call processing are highlighted as strong features, though the LDAC codec's power draw and occasional app or connectivity quirks are noted as drawbacks.
Everyday users love the NC20's feather-light comfort, impressive sound clarity, and the massive 80-hour total battery claim, often calling the audio "amazing" and the fit "barely noticeable" after an hour. Portability and waterproofing receive frequent praise, while the main pain points revolve around faster battery drain when using LDAC and frustrations with the companion app's initial setup.
