TOZO NC9 true wireless earbuds pair aggressive hybrid ANC and long battery life (Bluetooth 5.3, customizable app EQ) with waterproofing and a visible case battery display. They deliver strong noise reduction, IPX8 waterproofing, and up to ~59 hours total playtime, but tradeoffs include modest mic quality, a background hiss with ANC enabled, and fit variability for smaller ears — a solid budget ANC option with feature-rich software, good for workouts and commuting.
Buy if you want aggressive ANC, IPX8 waterproofing, long battery life, and deep app EQ tuning; avoid if you need best-in-class call microphones or have very small ears.
