Tenwin A week after the release of the first self-developed ANC active noise canceling headset, Bluetooth headset factory took advantage of the hot iron and released an affordable ANC active noise canceling headset TW-T22

This ANC active noise canceling headset has an active noise canceling depth of 23db. It adopts the Bluetooth AB8896 chip, which has higher sound quality and stability, but the price is very close to the people. It is a very cost-effective ANC active noise canceling headset. Not much to say, just look at the parameters
