Noise cancellingAdaptive active noise cancelling (ANC) · Aware (ambient) mode

ANC picks up outside sound with microphones and cancels it with an opposing signal. Bose says this generation changes cancellation levels more smoothly when sudden noises occur.

Bose		Active noise cancelling (ANC) and ambient sound mode

ANC measures outside sound with microphones and produces an opposite wave to reduce steady hum; in an open design the effect is more limited than in sealed earbuds.

Design—Open-type stem earbuds without silicone tips; silver and white

The open design does not seal the ear canal, so it avoids a pressure feeling over long use but isolates less than tipped models. Fit varies with ear shape.

Samsung
Driver and microphones—11 mm dynamic driver (one-way); 3 mics + voice pickup unit (VPU) per earbud

The VPU picks up the wearer’s voice through bone vibration to help separate speech in noisy calls.
