### 2/5 — AWFUL IN SO MANY WAYS

*2026-07-25*

It takes a good 20 seconds to "connect to the servers" and there's no dark mode. You have to open the app and have BOTH earbuds in before it even STARTS! Extremely frustrating!!

### 2/5 — Incomplet

*2026-02-23*

Pas assez de bandes d’EQ donc moins précis dans les modifications, pas de possibilité d’avoir plusieurs égaliseurs sur le meme profil sonore, pas de possibilité de modifier le profil sonore une fois établi donc si le résultat ne nous plait pas, on doit forcément en faire un autre et prier pour que ça sonne comme on aimerait… c’est dommage.

### 2/5 — なんで起動が不安定なんだろう

*2025-10-13*

アプリとしての最低限動作すら、できないことが多い。サーバーに接続するのはいいがもっと早く接続してください。イライラします。
パーソナライズ機能は素晴らしいのに、。

一つの最高の能力を、ほかの粗悪な部分が足を引っ張るから、結果的に悪いレッテルを貼ってしまいます

### 1/5 — ドブ金

*2025-09-06*

ゴミ。
1つしか所持していないのに2つ所持していることになりペアリングを求められた。しかもムカつくことにペアリングしないと自分の使っているイヤホンの設定をいじれない。
つまり未所持のイヤホンを繋げなければアプリの使用は不可能。ゴミ。
購入したばかりの時は1つのみだったが急に2つ所持している判定を受けた。なぜ？？
スマホもイヤホン2つ所持している判定でBluetoothに2つ接続されている。2つ分接続されているせいか、音質が売りにも関わらず音質がゴミ。
あとBluetooth接続時に爆音で接続したことを伝える音声が流れる。流れないようにしたかったが、このアプリではできないようだ。
もしできるとしても分かりづらい。私は見つけられなかった。
欲しいのに無い機能が多い。
使用して1年経っていないのに、性能が悪くガッカリした。期待していただけに残念。

### 1/5 — Stopped working

*2025-08-15*

Denon Perl Pro refuses to connect in the app. I don’t know if this is due to recent updates. The bluetooth on the headphones themselves work fine but whenever I open the headphones app it gets stuck on connecting to the headphones and times out or gives me an error stating connection status unknown

### 1/5 — Can't set up Personalized Hearing Profile

*2025-07-30*

Ordered a spare Denon Perl Pro and tried to set up Personalized Hearing Profile but ended up with a Blank white screen and Bluetooth disconnect notification during the hearing measurement process. I will have to return the new pair of Perl Pros. really disappointed.

### 2/5 — イコライザーが勝手にリセットされます

*2025-07-24*

設定は保持してリセットされないように改善をお願いします

### 1/5 — AH-c630w

*2025-07-12*

There no setting’s development for ah-c630w?

### 1/5 — Registrieren erforderlich

*2025-07-03*

Die App funktioniert nur online wirklich gut. Würde mir mit dem Wissen keine Denon mehr kaufen. Klang hin Klang her.

### 3/5 — Almost Perfect

*2025-06-16*

I’ve only been using the app for a few days, but the only qualm I have is the whole needing both earbuds on to access the app. I can only wear one earbud a time at work and if I need to check something real quick needing to go and grab my other earbud is super annoying.

### 1/5 — 一生接続

*2025-06-13*

接続中から動かずアプリ利用出来ず。話にならない仕様です。

### 1/5 — Fix your damn application!

*2025-05-12*

Can’t connect my Perl Pro to the app, the connection keeps on timing out. Locking me out of all the fonctionnalities!!! Demon support is doing absolutely nothing to fix this despite my numerous inquiries and told me to get a new pair… a ware, because the Perl pro are effectively the best earbuds money can buy. Remove the server ba and let us do our life locally.

### 1/5 — Now even worse

*2025-04-19*

App was poor before, only working when earphones are connected, no ability to alter settings whilst they’re charging in case. After update, I now don’t get any battery warnings, just “battery critical” they then shutdown 2 seconds later. Utterly useless. Wouldn’t buy denon earphones ever again

### 1/5 — オフラインで使用不可

*2025-04-15*

オンライン接続していないとアプリが起動しないのは、ヘッドホンのアプリケーションとして欠陥でしかない

### 1/5 — iPhone16pro

*2025-02-13*

アカウント制作はできるけどイヤホン認識しない。
対応してぇ

### 2/5 — Vraiment pas top.

*2025-02-05*

Impossible d’utiliser l’application, et notamment le mode personnalisé, sans réseau. C’est un vrai problème.
Impossible également d’activer/désactiver la réduction de bruit directement depuis les écouteurs. La seule possibilité avec les écouteurs est de passer du mode ANC au mode transparence. Il faut nécessairement passer par l’application pour désactiver le mode ANC/transparence. Enfin, le volume sonore minimum reste trop élevé. Serait-il possible de faire quelque chose lors d’une prochaine mise à jour ?

### 1/5 — 接続が遅すぎる

*2026-07-16*

アプリを開いてサーバーに接続されるまで数分以上はかかります。サッと開いて調整することができないので非常にストレスが溜まります。
イヤホン自体はいいのでもったいないです。

### 1/5 — 接続されるまでが長すぎる

*2026-07-03*

1秒でも早く改善してください

### 1/5 — 接続しにくい

*2026-05-28*

なんで接続するのに何回も何分もかかるの？

### 1/5 — Account/Servers

*2026-05-05*

The app has such potential. The big issue is it needs to connect to Denon servers to work. Thus it Is unfunctional on airplanes or at my farm. It really makes no sense. Even with Wi-Fi, half the time it cannot connect.

### 1/5 — Too many bugs

*2026-03-16*

Offline mode does not work, meaning you cannot configure anything w.r.t. headphones without internet. Kicks you out into an endless loop. Touch controls are limited—only toggling transparency mode works; you cannot toggle between e.g. noise cancellation and “off” mode.

### 1/5 — 接続

*2026-02-04*

何回やっても
｢デバイスへのBluetooth接続が失われました。｣とでる。
不快。

### 1/5 — Good Sound Not the Product/Support

*2026-01-10*

I really like the Noise Cancelling earphones from demon but two things that suck are the weak app support to connect it with, there’s just too much problem when it came down to connect the two together and the support is subpar. The worst is that my right ear phone must have some sort of manufacturing defect because it noticeably run of out of battery MUCH quicker than the left one. So I’m constantly having to put it back in its case to recharge. I can’t speak for the rest of their products but if you’re looking into their earphone I would maybe consider a different brand.

### 1/5 — Terrible app and head

*2025-12-31*

Not up to Denon AV standards.  Perl Pro would not fit in my ear and “create a seal” to do the sound customization, even after changing ear tips.  The earphones also have basically zero noise canceling .

### 1/5 — 改善されてない

*2025-11-18*

エラーで落ちまくり。テストしてから公開しろ！

### 1/5 — ヘッドホンとは

*2025-09-09*

DENONヘッドホン書いてるから入れてんのになんで接続するアクセサリがイヤホンしかないんだよ。

### 5/5 — Норм

*2026-04-18*

Норм

### 5/5 — Haters

*2025-11-28*

I don’t understand why people are worried they have to make a account to use the app, like bro it’s not a big deal if it  is just make a dummy account because without the app you can’t enjoy these amazing earbuds.  As far as sound they crush any buds I have tried and I have almost all of them.  Now for comfort they are not bad but compared to my Bose silent buds it’s not even close.  But they stay in my ears and that’s a huge plus. Can’t say the same for apple pro buds that i really enjoy but they don’t stay in my ears at least.  But if you want mids highs super bass then you can’t go wrong.  These and the Bose. The only thing that’s lame is you can’t change the volume unless you press and hold or something weird. That’s gotta be fixed if I’m paying over $350

### 5/5 — With the latest version this is 5/5

*2025-01-02*

Seems like someone at Denon check the reviews and decided to fix thing up. Kudos making the app great as the product

### 5/5 — アプリ・本体ともに満足です!

*2024-12-31*

私はこのアプリを使用して上記のように感じました。

　このままでも十分なのですがもし可能であればイヤホン本体に加えてケースの充電もアプリで確認できるようにしていただきたいです。
(すでに実装済みであればすみません。素晴らしいアプリだと思います！)
　また、現時点でイコライザは一つのプロファイルにつき一つしか保存できませんが、個人的には複数保存できると嬉しいです。

　良い製品を本当にありがとうございます。これからも愛用させていただきます。

### 5/5 — Easy to set up, excellent sound

*2023-11-07*

The app walks you through set up with little fuss. Adaptive personalized sound is calibrated in 2 minutes. I love my headphones!!

### 4/5 — It took a while to set up

*2025-01-14*

When creating my Personalised Sound Profile, it got stuck at the first step for hours.

But gave it another attempt hours later and was successful.

I wish there was a function to go to the previous song on the headphones.  An option for this did not appear to exist when I was customising my inputs.

### 4/5 — イヤホン本体がケースに入ってるかを判別してくれない

*2024-02-29*

表題の通りです。
そのためPearl Proを使用していない時に勝手にイヤホンに接続されてしまい、携帯のスピーカーや別のBluetoothイヤホンから音が出ないのがかなり頻発して若干ストレスを感じます。
ソフトウェア側で改善できるのであれば次の次ぐらいのアプデまでには改善していただけると嬉しいです。

### 4/5 — Great app and headphones

*2024-01-19*

Have had no issue with this app. Firmware update of headphones and set up went flawlessly. I am loving the customized sound.

### 3/5 — Slow to start

*2026-06-04*

It takes a good 20 seconds to "connect to the servers" and there's no dark mode.

### 3/5 — App

*2026-05-16*

So I bought Denon  pearl pro earbuds and I have an iOS device.  The brochure that came with the earbud says that these earbuds have spatial audio for iOS and android but has no head tracking with the spatial audio. I download  the app and set up went great and some of the things that people are talking about on here about the  earbuds that doesn’t have control has now been updated…. I guess because now you can do a lot with the earbuds by customize what it will do for as turning on and off features like transparency right on the earbuds, but on my app, there is no spatial audio. I reached out to the support team and they say that there is spatial audio on the app and that I’m not looking in the right place, but I have yet to find it in the app. I have reset the earbuds  and the phone itself made sure everything was up-to-date, but still do not see a spatial audio button Even though the spatial audio was not supposed to have head tracking….spatial audio was one of the things that I enjoy and was hoping when I purchased these that there would be spatial  audio , but it doesn’t show it when you download it to your phone which I have iOS but the support team says it does have it but I have yet to see It no matter what I do.
