Image of Knowles KN1 Reference Design Wireless Earphones - Overview

The KN1 reference design is a fully-functional true wireless earphone demonstrating how a modern device can achieve premium sound together with active noise cancellation, or ANC. These are two features in increasing demand. A 10mm dynamic speaker provides strong bass both for music and for effective ANC. The Knowles balanced armature tweeter model RAN provides extended treble that makes music come alive. The KN1 reference design also has three Knowles SiSonic™ microphones. One faces the ear canal for feedback ANC and two are on the outside for feedforward ANC, ambient sound pass-through, and clear voice calls.
