Swiss Cougar Nagoya Active Noise-Cancelling TWS Earbuds

The noise-cancelling technology featured in these True Wireless Bluetooth Earbuds allows you to suppress outside noise while using them, whether with the sound on or off. This is especially useful on an aeroplane, or when working in an open-plan office environment. The earbuds themselves are universally designed to fit the ear comfortably, and they have a light, soft rubber coating. They are most suitable for everyday use, and not necessarily for rigorous sporting activity. Featuring loud and crisp sound, for listening to music and podcasts or watching videos, and the built-in microphone facilitates easy calling, with clear sound at both ends of the call. Pair the earbuds once with your device (phone, tablet or laptop), and you won’t need to do so again – they will automatically pair thereafter, as soon as you remove the earbuds from the case, providing your device has Bluetooth mode switched on. case: 5.7 ( l ) x 4.6 ( w ) x 2.7 ( h ) cm ABS & silicone charging cable and user manual are included Bluetooth V5.3 + BR + EDR + BLE Bluetooth distance: 10 metres 30db ANC + 4-mic ENC noise-cancelling frequency range: 20Hz - 20kHz built-in microphone supports call pick-up case battery: 30
