Denon PerL Pro AH-C15PL Black

Two people listening to the same song on the same earbuds never perceive exactly the same sound. PerL Pro tackles that reality head-on: it measures the way you hear and builds a sonic result that suits only you, drawing on Denon’s long experience in headphone design and its distinctive approach to tuning.

Masimo AAT personalisation

Masimo Adaptive Acoustic Technology creates your personal hearing profile through a short process in the Denon Headphones app. The earbuds play test tones, record how your ears respond and automatically adapt their output across the whole spectrum, with no manual equaliser required and no guesswork on your part.

Titanium diaphragm drivers

Each earbud features a 10 mm dynamic driver with a triple-layer titanium diaphragm, designed for ultra-low distortion. The frequency response extends from 20 Hz to 40 kHz, so the full content of high-resolution recordings is put to work, from the deepest bass notes to the finest overtones.

Tuned by ear

The final tonal balance was set by Denon’s Sound Master through many hours of listening. The aim is a sound with clear mids, controlled bass and natural resolution that never becomes tiring, even after long listening sessions on the go.

Immersion Mode

For those who want more energy in the low end, Immersion Mode strengthens the sense of bass. It is easy to adjust in the app and can be matched to whatever genre of music you happen to be listening to.

Personalisation pays off most when the signal reaches the earbuds without losses. PerL Pro combines the most advanced wireless codecs with spatial audio technology to deliver an experience that comes close to listening on high-quality wired headphones, wherever you happen to be.

Qualcomm aptX Lossless

With compatible phones, aptX Lossless support enables wireless transmission of CD-quality music without data loss. aptX Adaptive, aptX, AAC and SBC are also supported, so the connection adapts to every source, from Android handsets to iPhone, always using the best codec available.

Dirac Virtuo spatial audio

Dirac Virtuo moves the music out of your head and places it in front of you, as you would hear it from a pair of loudspeakers. The stereo image gains depth and width, something you will especially enjoy with films and series.

Adaptive noise cancelling

Adaptive active noise cancelling adjusts its strength to your surroundings, from a quiet office to an aircraft cabin. With Social Mode you can hear what is happening around you without taking the earbuds out.

Bluetooth 5.3 and Multipoint

The Bluetooth 5.3 connection is stable and efficient. Multipoint keeps the earbuds connected to two devices at the same time, while Quick Switch makes moving between them a matter of seconds.

Looking after your hearing

When outside noise is reduced, there is no need to turn up the volume to hear the details. That protects your hearing over the long term, while the personalised AAT profile makes sure music still sounds full and balanced at low listening levels.

A premium earbud has to be just as convincing on calls, comfort and battery life as it is on sound. PerL Pro covers the full range of everyday use, from a work meeting to a training session or a long flight, with thoughtful details that make a real difference over time.

Crystal-clear calls

Four microphones on each side, two of them bone-conduction, isolate your voice from surrounding noise. With aptX Voice, calls are transmitted in super-wideband for more natural and intelligible speech, so the person on the other end hears you clearly.

Comfort and stability

The box includes silicone tips in XS, S, M and L, one pair of foam tips and two sizes of Secure-Fit wings. Weighing 8.6 g per earbud and rated IPX4 against sweat and rain, they stay comfortably in place for hours.

Battery life and wireless charging

The earbuds deliver up to 8 hours of playback and up to 24 hours in total with the case. Five minutes of quick charging gives one hour of listening, and the case charges either over a USB-C cable or wirelessly on a charging pad.

One-touch control

Four programmable touch commands per earbud, fit detection and automatic power on make operation simple. Every setting, from your hearing profile to spatial audio, is available in the Denon Headphones app.

A case that goes anywhere

The charging case measures 72.4 x 30.2 x 35 mm and weighs 55.5 g, so it slips easily into a pocket or bag. A USB-A to USB-C charging cable is included, and one hour is enough to fully charge the case, so you are always ready for the next day.
