Hearing is one of humanity’s most vital senses, granting us the ability to listen to sounds. However, when surrounded by the various noises of life, it can become quite bothersome, for in the real world, hearing is not only about delightful sounds. It was only when active noise-canceling technology became widespread, and noise-canceling headphones entered our daily lives, that everything fundamentally changed. Through intelligent sensing and precise processing, active noise-canceling technology can monitor and eliminate environmental noise in real time, allowing us to hear pure music. Whether in bustling city streets or on long journeys, active noise-canceling technology protects our ears, isolates noise, and keeps tranquility and music by our side.
Speaking of the most convenient active noise-canceling headphones to carry and use in everyday life, a compact and portable true wireless earbud is undoubtedly a great choice. But the phrases “compact and portable” and “powerful performance” can sometimes appear to be conflicting. The former demands repeated structural simplification of the headphones, retaining only essential parts while incorporating clever internal stacking to achieve a smaller size. The latter requires the internal hardware configuration necessary to accomplish various functions. Within TOZO’s well-received lineup of Amazon’s best-selling headphones, the NC series of true wireless earbuds, which is known for its active noise-canceling functionality, includes the TOZO NC7. This model achieves a delicate balance between “compact and portable” and “powerful performance.”
The TOZO NC7 features a compact and delicate bean-shaped in-ear design. The exterior has been carefully polished, conforming to ergonomic design principles, seamlessly fitting the contours of the ear to accommodate different ear shapes. This provides an exceptional wearing experience that remains comfortable even during extended use. Additionally, while maintaining a compact volume, the TOZO NC7 incorporates high-precision optical sensors to detect wearing status in real time, enabling automatic pause/play functionality. It’s optimized for daily and active scenarios, making it easy to switch on and off when wearing or removing the earbuds.
Furthermore, the TOZO NC7 earbuds are equipped with a large 70mAh battery, significantly extending their battery life. Combined with excellent power optimization, they offer up to 18 hours of continuous playback on a full charge. Paired with the 500mAh battery in the charging case, the comprehensive battery life reaches an impressive 72 hours. Even heavy users who listen to music and make calls for extended periods each day can enjoy TOZO NC7’s robust battery performance, lasting for an entire week and providing a dependable and stable wireless listening experience.
Moreover, the TOZO NC7 has received IPX6 waterproof certification, offering reliable water and sweat resistance. It’s the perfect choice for workouts and outdoor activities, whether sweating in the gym or caught in unexpected rain, users can confidently use the earbuds without worrying about sweat or raindrops causing damage, making them suitable for various usage scenarios.
The TOZO NC7 charging case, just like the earbuds, is compact and lightweight, easily fitting into pockets or handbags. Whether commuting to work, exercising, or traveling, users can carry it effortlessly. Additionally, the TOZO NC7 charging case features a built-in wireless charging coil, supporting wireless charging technology. There is no need for a charging cable; place the case on a compatible wireless charger to begin charging, and enjoy a seamless charging experience.
To provide a quality user experience, stable wireless connectivity is crucial for true wireless earbuds to compete with wired headphones. In this regard, the TOZO NC7 employs Bluetooth 5.3 technology, delivering stronger and more stable signals, significantly reducing the likelihood of wireless signal interruptions, and providing reliable wireless connectivity. Bluetooth 5.3 technology also allows the earbuds to achieve efficient audio transmission with lower power consumption, extending usage endurance.
After connecting the earbuds to a mobile phone via Bluetooth, users can easily personalize settings and adjustments through the TOZO app. For example, the app offers 16 preset EQ settings, each carefully calibrated to meet the requirements of different music genres. Users can select the EQ setting that suits their preferences, enhancing the appeal of every song. Furthermore, in terms of operation, the earbuds support customizable touch controls, allowing users to conveniently control the earbuds based on their habits and needs.
As a part of TOZO’s NC series, which emphasizes active noise-canceling functionality, the TOZO NC7 adopts a hybrid feedforward/feedback active noise-canceling technology that effectively eliminates external noise, providing an immersive listening experience. The app supports six noise-canceling modes, covering the majority of usage scenarios. The transparency mode allows users to switch to hearing ambient sounds when necessary, maintaining awareness of the surroundings. The depth of noise-canceling can also be customized, ensuring an optimal listening experience whether studying in a quiet library or navigating noisy city streets.
Beyond needing quiet for listening to music, clear communication during calls is equally important. The TOZO NC7 features dual-mic ENC call noise-canceling technology, utilizing two microphones to accurately capture your voice and eliminate ambient noise such as wind, traffic, and other disturbances. This ensures clear voice transmission during calls.
The TOZO NC7 boasts a 7mm dynamic driver unit for superb sound quality. With a wide frequency response range of 17Hz to 20kHz, it captures a broader range of audio details, enabling users to enjoy richer and more authentic music experiences. Whether it’s high, mid, or low frequencies, the TOZO NC7 accurately reproduces them, allowing users to hear the captivating aspects of music.
The TOZO NC7 accurately reproduces the essence of music’s audio quality. It maintains an overall balance, with a well-distributed representation across the entire frequency spectrum, resulting in a well-rounded listening experience without any noticeable biases. Taking the song “Like a Star” from Lala Hsu’s album “Gei” as an example, this track fuses the Disco vibes of the 1970s with House beats and Funky guitar riffs. The TOZO NC7 captures the vibrant rhythm of this retro dance track while fully interpreting Lala Hsu’s clear and melodious voice, creating a wonderful and soothing auditory experience.
Considering the compact and space-constrained design of the earbuds, its internal space is very limited and precious. Yet, TOZO NC7 has made meticulous use of this space, incorporating hybrid feedforward/feedback active noise-canceling, dual-mic ENC call noise-canceling, optical sensors, large batteries, 72-hour extended battery life, IPX6 water resistance, and more, which truly embodies the saying “Small but mighty.”
