Premium Sound Reference Design KN2

The KN2 is a TWS reference design tuned to the Knowles preferred listening response curve for the best music listening experience, this reference design was a collaboration with a 3rd party manufacturer of wireless earphones. KN2 features a state-of-art hybrid driver paired with an advanced Bluetooth system-on-chip (SoC) to deliver superior HD audio and active noise cancellation (ANC) performance along with other advanced features.

Knowles’ preferred listening response curve for earphone design began with analyzing 200 billboard hot 100 songs to determine the treble content of popular music. They then performed double-blind listening tests on a range of consumers to evaluate their preferred treble response when listening to that music. Knowles’ study revealed the treble response was essential for delivering the best and most satisfying music listening experience.

Designing and tuning an earphone that matches the high-frequency response of the Knowles preferred listening response curve is expected to consistently provide a highly satisfactory end user experience and solicit high ratings from consumers. KN2 is the first earphone reference design to be tuned to the curve, demonstrating how optimal treble performance brings breadth and life to music.

This device is not for consumer use, but is a reference design for manufacturers to utilize in creating their own products for consumer use.
