sonos ace driver impedance

I've searched high and low and can't seem to find any information on driver impedance anyone have a clue?

Why do you need to know this?

What driver impedance do other headphone manufacturers use? I always thought this was pretty standard (not variable), since they all rely on a normal headphone input signal.

Headphone impedance is hugely variable, from 16 ohms or less up to 600 ohms or more. My 300-ohm Sennheisers benefit from a powerful headphone amp.

However this discussion is irrelevant to Ace, as unlike some wireless headphones they can’t be driven passively. An analog signal is immediately digitised by the active circuitry, so the input power requirements are tiny.

Hmm, why would someone wanna know what parts is in a product?

It's very relevant. more so than if it was passive because you can't crank up the effect like on a amplifier. So if one were to put a new driver with to high resistance it would be whisper quiet or if to little resistance the driver would rattle and sound awful. been there done that🤯😂

If you want to get this involved with ACE’s internal circuitry and components, I suggest that you gear up and measure the transducer’s impedance and other physical characteristics.

Will do! Though It's very strange that the ace is the only headphone on the market that doesn't disclosure this very basic information.

If you’re wanting to butcher a Sonos Ace entirely and swap the drivers then you’ll also need to measure the power output of the internal amps. Obviously any warranty would be void and support non-existent. One wonders why anyone would buy an Ace in the first place.

Sorry, but this discussion is totally irrelevant for any of the Ace’s intended uses.

It’s not remotely strange. Again, in normal usage there is no way that the user could be exposed to the driver impedance.

It's like saying you don't have to know the size of the wheels on your car. A wheel is a wheel until you got a flat, then you kinda have to know, don't you agree? And seriously I just asked the freaking impedance, because I need to know and it's two digits of information that every other manufacturer include. What the heck is the problem? But I guess I learned my lesson as a first time sonos costumer, not a great experience.  And seriously who are you to decide if I need to know it or not? But like buzz said, I guess I'll have to measure it myself even if he probably knows the answer.

What makes you think ​@buzz “probably knows the answer”?  And trust me, you getting the reaction you did from multiple posters here is much more a reflection on the strangeness of the question than any overarching culture of exclusion on this forum.
