PerL, Denon's abbreviation for Personalised Listening, is a new two-model range of wireless earbuds leveraging parent company Masimo's patented “Adaptive Acoustic Technology” (AAT), which enables you to create a personal audio profile for a unique listening experience - possibly the result of the suspected Nuraphone purchase.

Consisting of the premium Denon PerL Pro and the slightly less-equipped Denon PerL. Both noise-cancelling earphones feature AAT, designed to automatically measure your hearing to create a profile perfectly tuned to you by measuring faint otoacoustic emissions (OAEs). These OAEs are analysed to determine your ears' sensitivity to given frequencies. The results are then crunched by the AI-powered Denon PerL app, adapting the sound to provide your bespoke hearing profile.

Joe Kiani, Founder and CEO of Masimo, told StereoNET:

The era of one-sound-fits-all is over. PerL automatically determines the optimal sound for each individual to cater to your unique ears. I am personally blown away by how good PerL Pro is. I have not heard my music like this since I was 18… We can't wait to have our customers join us in this new paradigm.

Furthermore, Denon boasts that the PerL Pro buds provide “a streaming experience similar to listening to a CD” while offering a surround sound effect courtesy of Dirac Virtuo that “enhances the overall audio experience”. Additionally, the PerL Pro gets two-way multipoint connectivity while supporting Qualcomm AptX Lossless audio and Bluetooth 5.3, adding aptX Adaptive, aptX Classic, AAC and SBC to the codec list.

Meanwhile, alongside the AAT tech, the standard PerL model features Bluetooth 5.0, supporting AAC, SBC and standard aptX codecs. ANC offers a transparent “social mode”, allowing in some of the outside in. The PerL is loaded with four mics, with the PerL Pro boasting eight microphones for upgraded noise cancelling, automatically adjusting the cancellation level according to the amount of environmental noise.

The PerL Pro is quoted as achieving eight hours of battery stamina on a single charge, with a total of 32 hours via the charging case via a USB-A to USB-C connection. A five-minute quick charge boost translates to an hour of playback. PerL offers six hours of battery life on the earbuds, 24 hours with the charging case, and they'll need a ten-minute quick charge for an hour of playback.

There are a limited number of Denon PerL Pro and PerL available in the USA, with models arriving in the UK this autumn costing £299/ €349 and £189/ €199, respectively.
