Wireless earbuds have become a staple for people who spend their day in calls, commutes, or noisy environments. If you're considering active noise cancelling earbuds, you're likely weighing whether the technology is worth it, and whether a particular model suits your life. The TOZO NC9 2024 represents a solid option in this category, with features that address the most common needs: call quality, battery life, and audio customization. This guide walks you through what matters when choosing wireless earbuds with active noise cancelling.

What Does Active Noise Cancelling Actually Do

Active noise cancelling, or ANC, uses microphones to detect outside sounds and then cancels them out by playing opposite sound waves through the earbuds. The depth of noise reduction is measured in decibels (dB). The TOZO NC9 2024 offers a maximum noise reduction depth of 45dB, which means it can significantly reduce low-frequency sounds like airplane engines, traffic, and air conditioning hum. This is most useful if you work in open offices, take public transport regularly, or need to concentrate in variable environments.

One thing people get wrong is expecting noise cancelling to work equally well for all sounds. High-pitched noises like voices, sirens, or metal scraping are harder to cancel than low, constant tones. If your main problem is chatty colleagues rather than background hum, active noise cancelling may not solve it alone. The TOZO NC9 2024 includes a transparent mode, which lets you hear your surroundings without removing the earbuds. This is handy for safety during outdoor activities and for quickly engaging with someone without taking the earbuds out.

Call Quality and Microphone Performance Matter More Than You Think

If you're in back-to-back video calls or take frequent phone calls in varied environments, microphone quality is genuinely important. The TOZO NC9 2024 uses six microphones combined with environmental noise cancellation (ENC) technology to isolate your voice from background noise. This means the person on the other end hears you clearly even if you're in a coffee shop or next to a construction site.

Test call quality before committing to any wireless earbuds model. Ask a friend or colleague for honest feedback on how you sound during a call, especially in less-than-ideal conditions. The difference between clear audio and muddy audio makes a real difference to your professional presence.

Battery Life and Daily Usage Patterns

The TOZO NC9 2024 advertises 59 hours of playtime with active noise cancelling turned off. Real-world usage depends heavily on your habits: how loud you listen, whether you use ANC continuously, and how often you use features like transparent mode. The charging case extends total listening time significantly, but note that you're tethered to when you can charge the case itself.

If you're using earbuds for eight-hour workdays, you'll want them to last at least a full day without charging. If you mainly use them for commutes and gym sessions, a shorter charge cycle may not bother you. Consider your typical day: do you need to go 16 hours away from a charger, or can you top up at lunch or in the evening.

Sound Customization via App

The TOZO NC9 2024 earbuds connect to a companion app that offers 32 different EQ settings. This means you can adjust bass levels and tailor the sound to your listening style. If you listen to a mix of music, podcasts, and video calls throughout the day, the ability to switch EQ profiles can be useful. The app also lets you adjust noise cancellation modes and access the EQ sharing zone, where you can see settings other users have created.

However, app-based features require that your phone stays nearby and that the app keeps working with your device's operating system. Over time, apps are updated or discontinued. If you want earbuds that sound good without relying on software, this customization layer may feel like unnecessary complexity.

Fit, Comfort, and Durability

The TOZO NC9 2024 comes with six sizes of replaceable ear caps. Finding the right size is critical: too loose and they'll fall out; too tight and they'll hurt after an hour. The correct fit should feel snug but not pressurised, and they should stay in place when you move your head or exercise. Because earbuds sit in your ears for hours at a time, comfort compounds quickly. A model that feels fine for 30 minutes can become painful over a full workday.

These earbuds carry an IPX8 waterproof rating, which means they can handle sweat, rain, and even brief immersion. If you'll use them at the gym or outdoors, this durability matters. Clean the ear caps regularly to maintain hygiene and audio quality.

Wireless earbuds with active noise cancelling are practical for focused work, calls, and travel. The TOZO NC9 2024 addresses the core use cases: effective noise reduction, reliable microphones for calls, and extensive battery life. Choose them if you genuinely spend time in noisy spaces or need professional-sounding audio during calls. Ensure the fit works for your ears, and test the microphone quality before relying on them for important conversations.
