DenonPerL Pro True In-Ear Wireless Earbuds, Personalised Sound Profile, Noise Cancelling Earphones, Water Resistant, Built-in Microphones, Long Battery Life - Black

I've owned a fair few wireless earphones/headphones and sound quality-wise these have been the best by a country mile. Only thing I've noticed on my phone (Xperia 5 V) is that the sound quality will drop if you leave Apple Music open whilst playing music, other than that if you come out of the App itself it'll revert to the highest quality your phone will support

The Good: Really nice sound. Clear differentiation between different instruments and track elements. Comfortable to wear. The storage box is feels sturdy. The automatic audio tuning is a marvel of modern technology; this feature has to be used to get the best out of these earbuds. I expect these earbuds to last me quite some time.The Bad: Why don't earbud manufacturers make storage cases with ejector buttons for the earbuds? Your guess is as good as mine. The earbuds are held in place magnetically. It can be fiddly to get them out of the case. I say that as someone with good dexterity.The Ugly: The control app works well but needs a few tweaks. The app can only be installed onto an Android / iOS device. This limits the app's usage to phones or tablets (I've not tried it on a tablet yet), or a user could install Android into a virtual machine (emulator/hypervisor). We need an app that works on desktop, laptop or smart devices like an Amazon Echo. Another issue with the app is that an account needs to be registered with Denon before it can be used and each time the app is restarted the account needs to be logged into. Why does the app need my name, my age and my gender? It shouldn't need any info about me. And why does the app sync with the Denon cloud service? I'm sure it does not need to do that in order to help me control my earbuds.Overall I am very happy with these earbuds. They are comfortable. They sound good. They look smart. I just wish the app could be installed onto a wider range of devices and OSs and that it did not require me to sign in to Denon's cloud service each time I want to manage my earbuds.

Firstly let's start with the pro. The major pro. The sound. As other people have stated the default mode is underwhelming but when using the automatic tuning option they are absolutely transformed. The sound quality beats even the Senn momentum 4, Sony Xm5 and B&W2. I would say it goes to number 1 on that particular list.Now the cons and which is why I had to send it back. Firstly they are huge in the ear. I have big ears and these things were absolutely massive. But having said that they looked quite stylish with the Denon logo very prominent. This is a half con half pro.The real con is the connectivity. In a world of seamless connectivity these were awful. I had several drop outs which you never get with say the Momentum 4 (I never had a single drop off with these). Also the app is underwhelming. Not as many customising options as I would like. Oh and sometimes I had trouble changing tracks sometimes. It didn't happen frequently but just enough to annoy me. And finally the noise cancellation was only 3 star. I've had much better.So in conclusion sensational sound of that there is no doubt, but the cons are just enough to put the buyer off. If you're looking for a fantastic all rounder with zero flaws, i would say the Senn Momentum 4 or even the Sony XM5 as a very close second.

I used Sony WF-1000XM3, Sony WF-1000XM4, and Sennheiser Momentum True Wireless 3. When the batteries of the latter went bad, I started looking for a replacement. I initially got the Technics AZ80, but I found that the sound quality was below that of my Sennheisers. Also controlling volume was a bit awkward. I did like the smaller case, and the fit was quite good as well. But sound quality comes first for me, and for that reason I returned them.Then I purchased both the Sennheiser Momentum True Wireless 4, and these ones. The Sennheisers sounded like I was used to with the MTW3s, but these are quite simply on another level. After AAT tuning, it is safe to say that they are like no earbuds I have tried before. The organisation, instrument separation, delicacy... is just way better. Additionally, the fit is better than the Sennheisers as well. The only downside is that they are a bit large, and so is the case. But for me, that is totally worth it. There may be better sounding buds like the Bowers & Wilkins Pi8, but they are more expensive as well, and the fit is probably not as good.Noise cancellation performance is good as well. Maybe not best in class, but I think it is better than my MTW3s, so I'm good with that. Transparency mode works fine too. Again, maybe not the best, but these are earbuds; as far as I'm concerned, that means they are made to enjoy music. And they let me do that incredibly well. I haven't tested call quality, but again, that's like... a 2% use case, maybe. the other 98% is about listening to music.
