Design and Connectivity

The design of the TOZO NC20 focuses on fit and durability.

A proper fit also contributes to passive noise isolation, which complements the active noise cancelling feature.

For connectivity, the TOZO NC20 uses Bluetooth 6.0, which is specified to deliver a stable and responsive connection across devices.

The LDAC and Hi-Res Audio Wireless decoding technology is designed to deliver studio-quality sound, preserving the detail in vocals and instruments as true to the original recording as possible.

For voice calls, the earbuds include a feature that reduces background noise during conversations. This is designed to ensure the user’s voice comes through clearly in various environments, such as at home, during a commute, or outdoors. The combination of the microphone noise reduction and the ANC feature aims to provide a clear communication experience even in noisy settings.
