Sonos Ace Ultra wifi

I have not seen this addressed here in the forums, you might check Sonos on reddit or call support.

How are you dealing with other radio energy sources in your home

If your problem is severe enough you might want to look at wired only headphones with no radio.

They technically don’t ship until Tuesday, the 29th. It’s possible some folks have received early shipments, but it’s feasible that your question would be answered in a review, or by calling Sonos Support to discuss it. Or, checking the sales page, although I didn’t see anything there by skimming it. 

This forum is generally a way for the public to help each other. While it is moderated by Sonos forum moderators, it rarely receives an ‘official’ response. You’re likely better off calling in.

All that being said, I’d be terribly surprised if there was a way to turn off Bluetooth. Like the Ace, the primary design is for sound via Bluetooth. Your best bet, if you’re concerned about RF, is to purchase wired headphones, although I’d be worried about normal RF associated with any electricity next to my head. 

thanks.  my concern may not be rational given all the RF around but it just “one more thing” and more than other wireless headphones.  i’ll call

Using deductive reasoning reference the Sonos Support Article below (see it here) WiFi for the Ace Ultra cannot be turned off. The defining statement is the use of the word  “room”. The Ace Ultra is not a “room” in the normal sense of Sonos speak; nor does it have a port for Ethernet connection.

Bluetooth although not mentioned in the article is only off (more correctly disabled) when the Ace Ultra is connected to a source via USB-C cable (such as a cellphone or tablet). 

EDIT:

FYI...The first generation Ace also uses WiFi (5Ghz) to capture audio from a compatible Sonos soundbar.

I wonder if the RF emissions numbers are in the certification documents. It would be interesting to compare the Wi-Fi and Bluetooth numbers.

I don't worry too much, now I have Bluetooth hearing aids all day, the cellphone with a much more powerful radio up close far too often. More distant, a half dozen local cell towers, several airport and weather radars, multiple Wi-Fi devices in the house and more at the neighbors. Years ago my only exposure was 12 volt DC from my solar panels and battery, haven't noticed a difference.

If you want some LIGHT reading on the subject of WiFi and RF exposure click this link. I’ve C/P’d the final statement below found at the end of the article. Draw you own conclusions.

• To conclude, human exposure to Wi-Fi RF fields, including exposure of children in schools, is very low and, in most cases lower than to other EMF sources in the environment. With this in mind, we, children and adults alike, should be following the practical advice to monitor and limit the use of Wi-Fi and mobile technology, as RF fields have become an unavoidable environment in and with which we have to live. There are almost no places on the Earth not covered with some of the RF fields. We have to monitor the ones which are man-made and research their possible impact on human and non-human genetic and physiological structure.

One has to ask, if you are worried about the possible hazards of EMF, why would you be interested in Bluetooth/WiFi based headphones?  Instead of using the Sonos Arc Ultra as wired headphones, isn’t it more practical (not to mention, in most cases, more economical) to purchase wired-only headphones than to ask a manufacturer to turn off their primary selling point?
