text: Preferred Listening Response Curve
  Knowles Tunes into Consumer Feedback to Unveil Optimal Earphone Music Listening
  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 that treble response beyond 10 kHz is 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.
  One response curve doesn’t work for everyone; hearing personalization is required. That’s where the Knowles Preferred Listening Response Curve combined with Knowles' Balanced Armatures come into play!
