Denon PerL True Wireless Earbuds - Active Noise Cancelling, Bluetooth, Personalized Sound with Masimo Adaptive Acoustic Technology, 24-Hr Battery Life, Wireless Charging, Black

so i love earbuds and have several pair. this one caught my attention because of the price, i had seen them before and they were double. the sound is amazing but only after you tune it with the app. mine fit better with foam eartips, from my personal stock, not the ones that came with it, but that's a very personal thing. they also fit me better without the wings, which is just as well because the case doesn't close completely with the wings on. the app was very helpful in personalizing the sound and fit. very happy with the sound.they are a tad bulky but comfortable. it's a little hard to get them out of the case if you don't have a fingernail. but sound is the most important thing, and i like them at least as well as my sony 1000x5's and they cost a lot less so i won't be so afraid to carry them around.

Just after the Sennheiser True Wireless Momentum 4 earbuds dethroned my Bose QC Ultra earbuds, mainly for the wireless charging case and punchy sound, the Denon Perl Pro came on sale. What was I supposed to do than to try this mythical contender that's relatively hard to find in the wild?Anyway, my home entertainment system is completely Denon and it never let me down. What really sparked my interest beyond that, however, is the fantastic smart speaker Home 250 which impresses me with the crystal clear sound, even compared to an Amazon Echo Studio and Bose Portable Smart Speaker in the same household. So, time to try out the Denon Perl Pro, with the 'Pro' being important for lossless codec support and custom sound profiles.The Denon Perl Pro is visually very similar to the standard model. The charging case is smaller than the Bose QC Ultra and the Sennheiser TWM4, but still larger than the Apple AirPods Pro 2. That may matter more to some than others. However, the Bose QC Ultra case being the only one of the mentioned examples that doesn't charge wirelessly despite feeling arguably the largest. Where the Denon case fails, however, is the ergonomics of removing the earbuds from it. It's easily the worst ergonomics of all four examples. Not a deal breaker but feels like an oversight nevertheless.The size and weight of the earbuds are sometimes mentioned as a negative. Neither bother me much, but if those criteria are important to you, it may be the main reason to look elsewhere. Maybe make sure to actually try them as this is a rather subjective thing. The large circular design sure looks different.The fit out of the box suits me just fine, just like the Bose and the Sennheiser. That is something I cannot say about the AirPods which never really fit me well. The touch buttons can be customized, with one odd difference: Tap-and-hold is reserved to reset/restart the earbuds, a unique feature, but also unavailable to the common "Volume Up/Down" function. The Tap-tap-hold is less intuitive and not always easy to execute.The iPhone app is decent, even if a bit temperamental, as the earbuds shut down in the case and become invisible to the app. Reconnecting then takes a few seconds, by far longer than any of the other earbuds I own. Once connected, you get basic settings in the home screen and most options are hidden away in the settings. There is no conversation awareness, a specialty of the AirPods, but spatial audio, environmental awareness (pass thru) are. The latter isn't configurable as to how to mix the environment with the music, but the spatial audio is easily the best I have heard so far. This is mostly since it doesn't try too hard to fake space, but is a subtle impact. That also means that audio quality actually improves, unlike the Bose QC Ultra implementation that's best when turned off.The ANC performance of the Bose QC Ultra (and AirPod Pro 2) are unmatched by the Denon Perl Pro (and the Sennheiser TWM4), but fairly useful in normal use. I don't use earbuds for making calls and cannot comment on the microphones in either of these earbuds.THE stand-out feature of the Denon Perl Pro is the Advanced Acoustic Technology (AAT). What sounds like a marketing term is surprisingly effective. The app plays sounds and measures "how you hear music". That's nothing short of black magic and sure worth a skeptical eye. The already good sounding earbuds really come alive with a customized profile. It was truly jaw-dropping how much more dynamic these sound with the personalized profile activated. Up to three profiles can be defined and stored. Just make sure to follow instructions to get a good seal and be quiet during the measurement.For me, the deciding factor was the deal during Prime Day(s) to give it a try and I do not regret it. It's easily one of my favorite earbuds. At full price it may still be a good choice, but less of a slam dunk.

TLDR: These are great earbuds and I don't think anyone will be disappointed with them, but their not perfectSOUND: 8.5/10 - They really do sound awesome, but...You have to go through the personalization, and better try it a few times to get it perfect. I also created profiles while on the bus and a crowded street, and I use them in those situations. So you really kind of get multiple earbuds with these. The sound is rich and full of life, deep base, clarity throughout the spectrum. I really think they bring music to life and provide a fun listening experience.So why 8.5? As amazing as they sound, their processing gives me a feel of too good to be true, so in a sense they lack transparency. I understand why some people would actually find this a good thing and say wow. To me, being used to studio grade equipment, they lack some transparency due to this.ANC: If you're one of these people that ANC gives you a feeling your head is being crushed, these might be for you. It's a relatively mild ANC, so it does not give me that painful feeling and it does a good job filtering out background noise. They're definitely not as strong as Bose/Sony, but for me that's a good thing.FIT: 8/10 - It took some tweaking but I got to a point they're quite comfortable. I don't think I can wear them for more than 2-3h straight though. Do note you need to learn how to put them in. They fell out of my ear till I did.QUALITY: 6/10 - The first time I used them they fell out of my ear and the outer silver ring broke. I had them replaced. The 2nd pair had a charging issue with the left bud, that disappeared before I managed to return them. I might just be unlucky but these two incidents are odd.To sum up, if you like the processes sound, I think they're really great. But I haven't compared them to other headsets.
