Score: 78/100
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.

The EarFun Air 2 are true-wireless earbuds offering 10 mm drivers, IPX7 waterproofing and up to 35 hours of total playback with fast charging. They lack active noise cancellation and advanced codecs, which may limit audiophile appeal. Ideal for active users seeking long battery life and rugged durability.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the EarFun Air for its impressive battery endurance, IPX7 waterproofing, comfortable lightweight fit, solid build with wireless charging, and a lively sound signature that delivers punchy bass and clear mids. However, they note the lack of active noise cancellation, an EQ app, and advanced Bluetooth codecs as drawbacks that keep the earbuds from competing with higher-end models.
Everyday users echo the professional praise for long battery life, comfortable secure fit, and reliable waterproof performance during workouts. They also appreciate clear call quality and the convenience of single-ear mode, while recurring complaints focus on bass becoming muddy at high volumes, occasional touch-control misfires, and the absence of ANC or an app for sound tuning.

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.
