TOZO NC9 Hybrid Active Noise Cancelling Earbuds - Balanced Bass

In this review the TOZO NC9 Hybrid Active Noise Cancelling earbuds are presented as a midrange, feature-rich option for daily commuters and casual listeners who want strong noise control without a premium price. The NC9s stand out for their three-layer hybrid active noise cancellation that combines outward and inward microphones with physical ear caps, and they also offer a transparent mode so users can hear announcements when needed. Battery life, waterproofing and an app with 32 presets make these earbuds a practical pick for workouts, travel and long listening sessions.

Key Features

• Hybrid 3-layer Active Noise Cancellation: Dual outward and inward microphones work together to cancel noise twice, while ear caps block about 90% of ambient noise reaching the ear canal.
• Transparent Mode: Lets outside sound in so you can clearly hear announcements or conversations without removing the earbuds.
• Built-in Dual Noise Cancelling Microphone: A dedicated internal and two external mics isolate the voice and reduce background noise for clearer calls.
• One-step Pairing: The two earbuds pair automatically when removed from the case, making setup with a phone quick and straightforward.
• Long Battery Life with Portable Charging Case: Over 13 hours from the earbuds and an additional 27 hours from the compact case, with ANC runtime around seven hours per charge.
• TOZO App with 32 Preset Modes: App access lets users tune sound signature across many presets to emphasize bass or achieve a balanced presentation.

Who It's For

These earbuds suit commuters, gym users and budget-minded listeners who want strong noise cancellation, a comfortable in-ear fit and a bass-forward sound. The IPX6 waterproofing and multiple silicone earcaps make them practical for workouts and outdoor use, while the transparent mode helps in transit where hearing announcements matters.

Users who demand the absolute highest call clarity in very noisy environments or who need advanced codec support for niche audiophile use should consider higher-end options. Some buyers also reported mixed long-term reliability, so those who prioritize extended product longevity may prefer a model with a longer proven track record.
