KN2, the first TWS reference design tuned to the Knowles Preferred Listening Response Curve for best music listening experience. 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 recently released its Preferred Listening Response Curve for earphone design. Knowles began by analyzing 200 Billboard Hot 100 songs to determine the treble content of popular music, 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 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.
- Qualcomm QCC5144 BT SoC with the aptX codec and aptX Adaptive for robust, low-bit rate, low-latency HD audio and Hybrid ANC.
- Within the earbud are multiple Knowles SiSonicTM MEMS microphones to enable voice call algorithms for enhanced noise canceling performance.
This compact, comfortable, and high-performance earbud alleviates design challenges and accelerates the time-to-market for TWS manufacturers.
