TOZO wireless earbuds NC3

If your main goal is to block out steady background noise, the TOZO NC3 has hybrid ANC, if you’d rather stay aware of announcements, it also offers Transparency Mode.

The appeal is broader than noise control. You also get call-focused microphones, app EQ options, and a charging case rated for extended listening.

The tradeoff is that the listed battery totals vary with ANC use, and a secure ear-tip seal matters for noise reduction.

Fit and sizing

The NC3 is an in-ear design with multiple ear-tip sizes, which gives you a way to adjust the fit and create the seal its noise reduction depends on. For a commute, try the tips that feel secure before turning on ANC, a loose fit can undermine both comfort and isolation. The listing doesn’t specify the tip sizes or provide dimensions, so there’s no exact sizing reference here.

For travel, ANC is designed to reduce steady, low-frequency sounds such as subway rumble, airplane engines, and air-conditioning hum. Transparency Mode takes the opposite approach: it lets nearby conversations and announcements come through without removing the earbuds. Need to hear a boarding announcement, or keep listening to music while staying more aware? That switch is useful for situations where full isolation isn’t practical.

Pros

The six-microphone setup with ENC is intended to reduce background noise during calls, which may help when you’re taking a meeting from a café or speaking while out and about. It’s a useful addition if calls matter as much as music, though the product details don’t establish how it performs in every noisy setting.

Battery life is a standout on the spec sheet: up to 13 hours per charge and 68 hours total with ANC off, or up to 9.5 hours per charge and 40 hours total with ANC on. A 10-minute charge is listed as providing up to an hour of playback. These are different listening scenarios, not one all-purpose runtime figure.

The 12mm dynamic drivers, Bass Plus tuning, and TOZO app’s 32 EQ presets give you options to adjust the sound for music, audiobooks, or streaming. That flexibility is more appealing than a fixed sound profile if you like to change the balance, shoppers who want fewer settings may not care about the app features. Bluetooth 5.3, automatic pairing, and a one-key reset round out the everyday-use features. IPX8 protection is listed for sweat, rain, and splashes, including workouts and outdoor use.

Final verdict

Worth considering if you want one pair for commuting, calls, and workouts, and value the choice between ANC and Transparency Mode. The long listed case totals and adjustable EQ make the NC3 more versatile than a basic pair focused only on playback. It’s not for you if you need detailed fit measurements, a guaranteed level of call clarity in every environment, or a single battery figure that applies with ANC both on and off. The practical choice depends on whether those modes and app controls are features you’ll actually use.
