performance of our acclaimed QN1e chip and goes even further. Improved noise canceling

performance and Bluetooth ‘System on Chip’ technology delivers the industry’s highest level of

noise canceling yet uses less power.

High-performance dual-noise-sensor microphones

Two noise sensing microphones per earbuds – one forward-facing and one backward-facing –

catch more ambient sound around you. This means more stable noise canceling and less

distortion at any volume.
