The fully wireless Denon PerL Pro True Wireless earbuds optimize sound reproduction personally for you. They measure and adapt according to your hearing, creating a unique playback profile using Masimo Adaptive Acoustic Technology (AAT). You will hear every detail with astonishing clarity. Equipped with CD-quality Qualcomm aptX technology and Dirac Virtuo spatial playback, the PerL Pro delivers an unparalleled listening experience. Choose silence by activating the active noise cancellation and immerse yourself in music or your own peace. If you want to hear what’s happening around you, the Social Mode passthrough allows sounds to come through the earbuds without having to remove them from your ears. The earbuds provide up to 8 hours of playback time on a single charge, and the charging case contains three additional charges, giving you a total listening time of up to 32 hours. Thanks to Bluetooth Multipoint connectivity, the earbuds can pair simultaneously with two devices. This means you can listen to music from your laptop and seamlessly answer incoming calls on your phone, as the earbuds automatically switch connection to the active device. Qualcomm aptX Voice technology ensures the highest quality voice calls in its class with a wide frequency range (32 kHz). Eight microphones accurately receive your voice, so the other party can hear you clearly. The Denon PerL Pro is IPX4-rated for sweat and water resistance, so you can comfortably use them while exercising or if a rain shower surprises you. With the Denon Headphones app (compatible with iOS and Android), you can create your own profile, customize touch controls, enable noise cancellation or Social Mode, and more. The Denon PerL Pro True Wireless charging case supports wireless charging. You can charge it on any Qi-compatible charging pad or traditionally with a cable.
