Sound that's customized for your hearing Denon's PerL true wireless earbuds offer sound that's personalized to the listener. After spending some time with these 'phones, I found that this feature was what impressed me most. I paired these noise-canceling earbuds to my phone via Bluetooth, then I immediately downloaded the Denon Headphones mobile app - free for Apple and Android(tm). The app unlock the "magic" of the Masimo Adaptive Acoustic Technology (AAT), which measures your hearing and serves up a unique tuning optimized for your ears.
