Denon PerL True Wireless earbuds let you create a personalized sound profile via Masimo Adaptive Acoustic Technology (AAT) for audio that is perfectly tuned to you. They're hand-tuned by the Denon Sound Master to deliver a vivid and spacious sound quality.

Your very own sonic profile

Masimo AAT creates your unique hearing profile by measuring very faint sounds called otoacoustic emissions (OAEs) produced by your ears. The earbuds then sonically shape your music so that you hear every detail with stunning clarity.
