Randomly the Airplay wouldn’t show up and I followed every troubleshooting measure possible. All in almost 8 hours of fiddling with a soundbar. I called Sennhieser directly and we still couldn’t get the issues fixed. The app and their products are the worst I’ve used for firmware reliability. The audio they provide though almost makes me deal with it. The sound they create saved them from a one star review. ### 2/5 — With soundbar *2026-08-09, version 4.9.3* Keeps losing the device. Good when it works though! But, it is always going blank, not showing the soundbar - usually I have to delete the app and re download but this time even this did not work! ### 2/5 — Doesn’t work half the time *2026-07-19, version 4.9.3* This app is great when it works. I would say when I first got headphones it worked but now its legacy and they don’t care it seems. I’ve had Sennheiser headphones for 10+ years but this has become so frustrating - its a simple issue as well. The headphones can be found but they never connect. Sometimes if I remove the app and redownload it works but its really just random it seems. ### 2/5 — I’m so sad *2026-07-16, version 4.9.3* The app keeps crashing every time I try to customize my sound personalization. I’ve tried over ten times and it crashes every time. I’ve tried multiple times in different ways. I’m so sad. ### 3/5 — Sound Personalization doesn’t work *2026-07-02, version 4.9.3* Whenever I try to make a profile for sound personalization, I get to the point where you’re able to drag that ball around then it instantly crashes the app. ### 4/5 — Crashes *2026-06-26, version 4.9.3* It’s a great app but it crashes a lot ### 3/5 — Settings Gray *2026-06-24, version 4.9.3* Just yesterday, settings are grayed out. Can't access. I deleted the app and reloaded it. Same issue. Please help. Can't turn on my sub. ### 3/5 — Please add WiFi WPA3 (not wpa3/2) support to soundbar plus! *2026-04-15, version 4.9.3* Nowadays,there are more and more deauth attacks to Ip cameras which still use wpa2 without PMF,WPA3 is becoming essential!Your ads indicate that the soundbar supports Wi-Fi6 which is always paired with wpa3 encryption.But during setup process,this app indicates the correct password is wrong.Since the hardware support Wi-Fi6,I think you really need to add WPA3 encryption support as soon as possible. ### 1/5 — よくわからない。つかえない。 *2026-03-01* dellのモニターAlienware 32 4K QD-OLED にambeo soundbar miniを接続するのに使ってます。 がアプリでエコモード？を解除したいが項目がない。 接続、音声出力は問題無かったがPCのスリープ解除後、音声が出ない。 再度音を出すにはコンセントを抜き差しする必要がある。 スマホ(iPhone.iPad共に)のWi-Fiは接続されているのに接続されて無いと言われる。 スマホアプリを起動して連携しても音声が出ない。数分経つと突然音が出たり出なかったり。 動画を停止するとよくわからない音が数分おきに鳴る。うるさい。 ### 4/5 — Computer. *2026-02-26, version 4.9.3* The more connections you have to the headphones, the more it tends to crash. The purpose of my review though, is to ask: why don’t you have an app for PC? I prefer to keep my headphones connected to my windows computer rather than my iPhone. I went to look for your app in the Microsoft store and it’s nowhere to be found. Please create an app for windows? Thanks. ### 1/5 — WHEN. ARE. YOU. FIXING. THIS. APP? *2026-02-26, version 4.9.3* The app has never been great quality. But it used to be really handy. It used to RECOGNIZE ALL MY HEADPHONES, without fail. It used to save my customizations. NOW? Refuses to do a thing with my PCX-550-II set, yet it works just fine with a budget set. I have attempted everything to get the late 2025 app to accept my PXC headphones. NOPE! The audio quality has been great on my PXCs, but come on. I don't like spending $400 for audio devices with ill-developed apps that will simply not recognize them no matter how many times I remove and connect the things. Sennheiser is a brand I have liked and used for a long time, for more than just headphones. They are not going to be considered for my next purchase if this is the poor service that continues. ### 2/5 — Sound personalization doesn’t work *2026-02-23, version 4.9.3* After the other application didn’t work - messed up with touch control and ANC, I came back to this application. Now my sound personalization can’t be retrieved and I can’t create a new one either. Both applications are messy. ### 1/5 — Çok zor değil *2026-02-14, version 4.9.3* Bu kadar köklü bir şirket hizmet verdiği 85 milyon insanın yaşadığı ülkenin dilini tanımalı uygulamada Türkçe olmaması saçma sanıldığı gibi bir şirket olmadığının kanıtıdır tarafınızdan ürün aldığım için pişmanım ### 3/5 — 設定聲音個人話到藍色點的那個步驟都會app跳出 *2026-02-07, version 4.9.3* 如上 ### 1/5 — トランスパレンシーとは？ *2026-02-03, version 4.9.3* トランスパレンシーのような謎の言葉ではなく、外音取込など別の一般的にわかる名前にしてほしい。考えないとわからない名前はストレス。 UIUXを考えるのは大事だと思います。 ### 1/5 — 458BT *2026-02-01, version 4.9.3* No los compréis solo funciona un casco por bt ### 2/5 — Meh *2026-01-26, version 4.9.3* It’s nice to be able to adjust the settings for listening quality, firmware updates fails as soon as attempts to load. That’s frustrating, along with fact my device doesn’t work on SmartControl + Ap where all their R&D and money goes. ### 1/5 — Bluetooth Connects to Phone But Not App *2026-01-26, version 4.9.3* I’ve tried on multiple devices to connect the Momentum 4 to the app on my phone, my wife’s phone and my iPad but it only connects to the Bluetooth on those devices. Without the app, I’m unable to access the features of the headphones. Annoying AF. ### 4/5 — Test der Version 4.9.3 *2026-01-21* Bin mit dieser App im Moment zufrieden doch gibt es lseid dem letzten Update mal wieder Tonaussetzer das war vorher nicht so! Vielleicht lässt sich dieser Fehler schnell abstellen! Fazit der Kopfhörer ist sehr gut! Doch die App nicht fehlerfrei! Bitte lasst diese Bewertung nicht im Nirvana verschwinden Danke ### 1/5 — WHEN. ARE. YOU. FIXING. THIS. APP? *2026-01-18, version 4.9.3* The app has never been great quality. But it used to be good. It used to RECOGNIZE ALL MY HEADPHONES, without fail. It used to save my customizations. NOW? Refuses to do a thing with my PCX-550-II set, but it works just fine with my cheaper, uncomfortable, at-work, budget set. I have attempted everything to get the late 2025 app to accept my PXC headphones. NOPE! Shame, as Sennheiser is a brand I have liked from long ago, and's for more than headphones. The audio quality has been great on my PXCs, but come on. I'm afraid they are not going to be considered for my next purchase. I don't like spending $400 for ill-developed audio devices. ## Most critical reviews (10 lowest-rated) ### 1/5 — Headphones keep opening voice control with no off setting *2026-08-22, version 4.9.3* Headphones keep opening voice control despite it being turned off in the system settings, and calling people. I love my headphones but I hate this feature. Let me turn it off. ### 1/5 — Completely Broken *2026-07-18, version 4.9.3* Ambeo Max Soundbar is grayed out. Search found it again. Tapping on the found device does nothing. Tried both iOS and iPad. Expensive device now dead. ### 1/5 — Horrible app *2026-07-01, version 4.9.3* This app is barely functional. It struggles to do basic things such as having the sound bar find the Wi-Fi every time I go to use the sound bar I need to completely go through a reboot of settings just to get it to work. ### 1/5 — Doesn’t connect to my Earbuds. *2026-06-13, version 4.9.3* Find my earbuds, but doesn’t let me do anything. CX 400BT ### 1/5 — Useless *2026-06-07, version 4.9.3* Sennheiser makes some incredible hardware, but the software is incredibly dysfunctional. I need to use this app to connect to my Ambeo sound bar and adjust most settings. I wish I didn’t have to go through a 45 minute dance every time I want to use it to adjust my bass or my surround sound. I wish I can say this app has seen some improvements over the last 3 years I’ve used it. ### 1/5 — Totally usless *2026-06-01, version 4.9.3* For cx 150bt does nothing. Literally. ### 1/5 — Useless *2026-05-27, version 4.9.3* Quite possible the most useless app for any of the speaker systems possible. The integration the interface. All of it, just beyond useless. ### 1/5 — will not pair *2026-05-03, version 4.9.3* my headphones are paired with my phone but this app doesn’t realize that they’re paired ### 1/5 — Low quality for premium price *2026-03-29, version 4.9.3* The app randomly disconnects, randomly shows empty page instead of tabs ### 1/5 — Utter garbage *2026-03-19, version 4.9.3* I have the sound bar and this app is utter garbage. Doesn’t work half the time (not exaggerating) and when it does, you’re pretty limited in what you can do with it. ## Most praised reviews (10 highest-rated) ### 5/5 — Absolut zufrieden – Ich kann die negativen Bewertungen nicht nachvollziehen! *2026-01-01* Ich nutze die Ambeo Mini nun seit einiger Zeit und bin absolut begeistert. Ehrlich gesagt verstehe ich die negativen Kommentare hier überhaupt nicht. Der Sound ist für diese Größe gewaltig! Viele beschweren sich über fehlenden Bass oder schlechten Klang, aber man muss sich einfach kurz Zeit für die Einstellungen nehmen. Nach der Kalibrierung und dem Anpassen der Werte (z.B. DRC aus) liefert die Soundbar eine Dynamik und einen Bass, den man so einem kleinen Gerät nie zutrauen würde – ich musste den Bass sogar runterregeln, so viel Power hat sie! Auch die Sprachverständlichkeit ist glasklar. Die Verbindung ist bei mir absolut stabil. Von mir eine klare Kaufempfehlung für alle, die echten Kinosound suchen! ### 5/5 — most intuitive and high tech app for headphones *2025-12-16, version 4.9.3* The senhieser headphones and app are probably the best ive ever had interms of features and tech (and ive spent about 3 grand on headphones. ). if senheiser made headphones with better anc qnd sound these would be the best in the market ### 5/5 — Très bien… *2025-11-24, version 4.9.3* …super appli pour effectuer les réglages sur le Momentum 4 (quel casque 👍), sert aussi de « tableau de bord », d’ailleurs je pense qu’elle est indispensable…👍👌 ### 5/5 — . *2025-08-13, version 4.9.3* . ### 5/5 — Good experience *2025-07-18, version 4.9.3* Overall I am very happy with my Momentum 4 and this app. Bugs was squished and now everything is working really fine. My Bose was freezing in Teams calls, here it just works! Great sound while listening to music, high responsiveness of the device, auto pause just working great. I have only one question: why ANC is bad during phone calls? ### 5/5 — Love it *2025-06-23, version 4.9.3* Best AirPods ever, I use them on iPhone way better than the apple ones by far. Keep it up 👏🏻 ### 5/5 — Sen *2025-06-21, version 4.9.3* Made my music experience so cool! Especially cool mods to :) ### 5/5 — Muy satisfecho *2025-06-05, version 4.9.2* Más de lo que esperaba, increíble lo amigable, los tonos bajos, altos literal se ajustó con mis carpetas de música ### 5/5 — Very good *2025-05-29, version 4.9.2* The best of all ❤️ ### 5/5 — 自分の買っているモデルの色も表示して欲しい *2025-05-16* 白のHD 450BTを愛用しているが画面に黒モデルが表示されるのは嬉しくないので、白のヘッドフォンを表示して欲しい。ユーザーの持っている機種の色なども再現して欲しいと思います。それ以外に負担は特にないです。 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
