So I just bought a pair of Sennheiser Momentum 4's.
I was using some Sony WH-CH700N's but thought I'd give myself an upgrade.
I have a Samsung Flip 4 phone and using the Sony's was great as I could allocate the NC button on the Sony's to use Alexa. I could keep my phone locked and folded in my pocket, press the button on the Sony's, hear a prompt tone, say the name of the song and artist and it'd play from Amazon music.
The Momentum 4's seem to be a big step back in functionality regarding this.
I try to go into the Alexa app and add the Momentums as a new device but they aren't found. The first time I pressed the button on the Momentums after set-up, a choice came up on my phone screen asking which voice assistant I wanted to use. I chose Alexa. So then I could press the button on the Momentums, ask for the song and it'd play. But... it won't work when the phone is on the lock screen. Pointless really.
Searching Google points to the Sennheiser smart control app having an Alexa button in the settings but it's not there for me.
I can't even figure out how to switch between voice assistants?
Odd how some pretty cheap Sony's have much better functionality... unless I'm doing something wrong?
I found a solution of sorts, but still have an unresolved issue.
The Flip 4 phone has a cover screen. This screen is fairly limited to what it can do as stock.
However, someone has developed an app called 'cover screen OS.' This app allows you to open apps on the cover screen.
Using this, and with the screen set to 'always on', you can open Amazon Music on the cover screen and it will respond to Alexa voice commands without having to touch anything on the headphones or the phone. And it stays active.
So with this solution, I don't have to press the button on the headphones or touch anything on the phone.
It's a nice solution.
What is still unresolved is how, after choosing Alexa as the voice assistant initially for the headphones, do I unbind this choice and choose either Google Assistant or Bixby instead?
A poster on Reddit has dangled a carrot saying they can swap between voice assistants on the Sennheisers, but hasn't shared how it's done despite my asking? On the M4's, after initial set-up, I pressed the button on the 4's and on the Flip 4 screen it asked which assistant I'd like to use. I chose Alexa.
But now I cannot choose or switch to another voice assistant. There's nothing in the Sennheiser App. Choosing different assistants in the phone settings doesn't change the behaviour of the button on the 4's. It still invokes Alexa.
Three factory resets of the 4's done, uninstalled and reinstalled the Sennheiser app three times but still the button is tied to Alexa. In fact, a factory reset of the phones doesn't appear to be that because the latest firmware stays intact and any personalised EQ profiles.
Contacted Sennheiser but no response.
So I've now got a button on the 4's that is Alexa specific and can't be decoupled.
If anyone knows how to switch between voice assistants on the Momentum 4's, could you help me out?
Many thanks if you can...
@ericpalonen maybe?
