Design:
The Denon PerL Pro have a flat, round outside surface and small in-ear tips. The matte flat surfaces have the brand name printed on them. Most people find them to be a very comfortable fit. They come with a variety of tip alternatives, including four different-sized silicone tips, a pair of foam tips (medium size), and two sets of stability fins to assist you attain a more secure fit.
It can be difficult to obtain a decent fit, especially with the foam tips, but once you do, they don’t cause much tiredness or pain and their controls are easy to use and very customizable. The touch-sensitive surfaces on the buds are big and sensitive enough that you only need a light tap to register commands. You can also grab the rim of the circular buds to readjust the fit without accidentally pausing your audio or turning up the volume. There are different audio queues for single, double, and triple taps, and you can activate voice prompts in the companion app and they are small, light, and portable, like most truly wireless earbuds. The circular buds are a little bigger than some, but they can still fit easily in purses and pockets.

They include a portable charging case. Although the matte coating attracts fingerprints and the top seems a little flimsy, the case itself is durable and portable. The broad exterior surfaces of the buds might make them difficult to remove from the casing.
It is equally solid, with no cheap-feeling components. The silicone ear tips are not flimsy, but they may tear or rip with prolonged use. The foam tips are less robust and will likely degrade faster, requiring replacement every six months or so, but this is to be expected given the material. The case’s hinge is also not particularly robust, and it may loosen or break with repeated use or if the case is dropped.
Sound:
The PerL’s journey began years ago with a company called Nura, which most recently had the NuraTrue earbuds.
The Denon PerL Pro have a well-balanced default sound profile. They don’t produce a rumbly, punchy bass response, and instruments and vocals sound veiled. However, their more neutral mid-range response helps instruments to sound present and clear in the mix. Turning off the ANC function modifies their sound profile. With ANC turned off, they create less rumble and punch in the low and mid-bass frequencies. A graph of the frequency response with ANC turned off may be found here.You can manually tweak the sound with a 5-band EQ in the app or with the ‘Immersion’ setting, which allows you to turn the bass amount up or down with a slider or the onboard touch controls.
You may build a tailored EQ with their Masimo Adaptive Acoustic Technology feature, which is supposed to adjust their sound to your ears, using their companion app. Unlike the Sony WF-1000XM5 Truly Wireless’ ‘Find Your Equalizer’ feature, which requires you to choose between different tones to assess your preferences, it generates a personalized EQ without any user input, however the test still includes a series of tones played via the buds and they have excellent bass accuracy. The range is slightly underemphasized, so the bass doesn’t overwhelm instruments and voices in the mid-range, but it’s also consistent, so your audio still has rumble and punch.
Battery Life And Charging:
They have a decent battery life. The manufacturer claims an eight-hour continuous battery life, but we measured little under seven hours. They recharge quickly, though, and the case carries around three more charges. One earbud can be used while the other charges in the case. They also have an auto-off timer and standby mode to assist preserve power when not in use.
Battery Type – Rechargeable
Continuous Battery Life -6.75 hrs.
Additional Charges – 3.0
Total Battery Life – 27 hrs.
Charge Time – 1.3 hrs.
Features:
The Denon Headphones app offers a good variety of features and customization options. You can access the Masimo Adaptive Acoustic Technology feature, which customizes the sound profile to your ears with a fit test and by playing a series of tones to check your ear shape. This creates a custom EQ and ‘profile’ for your ears. You can store up to three profiles in the app.
You can also activate or deactivate several features: spatial audio, ‘Social mode’ (a transparency mode that lets in ambient sound so you can hear your surroundings), battery saver mode, and high gain mode, which the manufacturer says increases the earbuds’ volume by 6db. The app also allows you to remap all of the controls on either earbud.
Conclusion:
While testing the Denon PerL Pros, I swapped out my regular active noise canceling earbuds and discovered that the good fit and calibration to how my ear “hears music” makes them a top contender for True Wireless Earbuds because they enhanced how I was hearing my music and pushed me towards listening how I should be listening to my music.
