Ultra Quietness by Hybrid Noise-cancellation
The dual-mic noise-cancellation technology is designed for precise noise-cancelling and reverse noise offset.
By advancing its technology, the TWS NB2 has elevated its noise cancellation to -40dB,30% deeper than the previous generations of Edifier headsets.
Crystal Clear Communication
The TWS NB2 offsets ambient noises through the main and auxiliary microphones to
enhance the users voice and provides a crystal clear call.
Simple and Compact Design
The design, fit and angle of the earbud was developed through a series of tests with seven different styled ear caps to ensure a comfortable fit for any user.
The 10mm Composite Diaphragm Unit
The 10mm composite diaphragm unit delivers detail-rich sound with a wider sound field.
Environmental Monitoring Mode
By simply double-tapping the left earbud, TWS NB2 users can conveniently deactivate the active noise canceling feature allowing them to ensure safety when crossing streets or to be able to listen for flight announcements at the airport, and more without removing their earbuds.
Enhanced Bluetooth Connection
The high-end chipset ensures a stable signal connection and further signal transmission.
While keeping the latency as low as 80ms, the TWS NB2 is ideal for an immersive gaming experience.
Extended Playback Time
The TWS NB2 features a 7-hour playback time with the active noise canceling feature on and an additional 18-hour playback time with the feature off to ensure all day use.
