TOZO NC9 Noise Cancelling Wireless Earbuds

The TOZO NC9 are hybrid active noise cancelling true wireless earbuds that combine up to 45dB ANC, six-microphone clear calls, IPX8 splash protection, and app-tuned audio for long-lasting everyday use.

Compact and feature-rich, the NC9 pair Bluetooth 5.3 connectivity with 10mm drivers, a smart charging case with LED battery display, and 32 EQ presets available in the TOZO app. They’re built to block distractions on commutes, make voice calls intelligible in noisy places, and survive sweat or rain while providing flexible sound shaping and lengthy battery life.

How effective is the noise cancellation for travel and commuting?

The NC9 use hybrid ANC to reduce ambient noise up to 45dB, which helps lower steady background sounds like engine rumble and air conditioning. You’ll notice quieter cabins and trains without muffling your music severely. A transparent mode lets outside sounds through when you need awareness for safety or announcements.

• Hybrid ANC system targeting low and mid frequencies
• Up to 45dB maximum noise reduction depth
• Quick switch to Transparent Mode for situational awareness

Will calls be clear in noisy environments?

Yes — the NC9 use six microphones with environmental noise cancellation (ENC) to isolate voices and suppress background interference. The system focuses on the speaker’s voice, improving intelligibility in street noise or busy offices. Call routing and mic placement are optimized for typical head movement and outdoor conditions.

• Six-microphone array for clearer voice pickup
• ENC reduces ambient noise during calls
• Suitable for remote work, rides, and hands-free conversations

How does battery life perform for daily use?

The charging case extends total playtime to around 60 hours with ANC off and about 40 hours with ANC enabled, so you can go several days between full charges. Each earbud offers lengthy single-use playback — roughly 14 hours without ANC and 10 hours with ANC — and the case’s LED display shows remaining power at a glance. Fast recharges bring the case and buds back quickly for travel or long workdays.

• Up to 60 hours total playback (ANC off)
• About 40 hours total playback with ANC on
• LED display on the case shows battery status

Can I customize the sound and fit to my preferences?

Absolutely — TOZO’s app offers 32 EQ presets and an "EQ Zone" sharing feature so you can tweak bass, mids, and treble or try community-created profiles. Physically, the NC9 include six sizes of silicone eartips to help you find a secure, comfortable seal that improves passive noise isolation and bass response. The combination of fit and app tuning makes these earbuds flexible for many music styles.

• 32 EQ options through the TOZO app
• Exclusive EQ Zone for sharing and downloading profiles
• Six eartip sizes for a personalized fit

Who is this for? The TOZO NC9 target listeners who need reliable ANC for commuting, long battery life for travel or work, and clear hands-free calling in noisy places. They suit people who value deep bass from 10mm drivers but also want the ability to fine-tune sound via an app. If you want splash-resistant earbuds with a visible case battery indicator and multiple eartip sizes for daily comfort, the NC9 are a practical, versatile choice.
