### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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
