So which iOS device should I buy to run TruePlay?

I’d also be interested in this answer Stanley, as I also had an iPod Touch 6th Gen which is no longer supported.

Will be interested to see folks advice :) 

I’d really urge you not to buy an electronic device to one time tune your speakers. Surely you know somebody you can bribe with tea and cake to come round and do it for you?

I tend to stay just back from the leading edge because this is cheaper. Another approach is to go for the leading edge, then use it as a trade-in for the next leading edge. This maximizes the trade-in value. It’s hard to exactly predict the year over year cost advantage of this approach. Many times there are attractive prices for last year’s model just after “new improved, get the latest!” has been brought out and before trade-in value declines too much.

You might want to look into TouchControl with your new iPad. With some JavaScript programming pretty much your imagination is the limit as to what you can control. I’m speculating, but with enough effort, I think that you could develop a SONOS controller that would be similar in features to the SONOS App. I doubt that it would be practical to include setup functions.

Overall I’m impatient with pokey user interfaces and this is a reason for me to gravitate toward the later, higher end units because they are faster.

FWIW: I’m not an Apple fanboy, I need the iPad for business and it’s my only Apple product. I did have an iTouch that I used for SONOS control.

I tend to move things around and reshuffle Sonos as a result, or I get a new one and move the old down the room chain, so it isn’t going to be a one time thing, probably average a couple times per year. I also like to experiment a bit trying to improve my results and that can be several re-tuning sessions across a few days.

Most of the folks I know have flip-phones or ancient Android or Apple phones. I had hoped for the grand-kids option but the local ones are Android users. Of the few friend possibilities, I don’t know them well enough to ask they install an app they have never heard of and let me play with their phone long enough to tweak all my rooms.

If folks can borrow an Apple often enough to meet their needs it is sure the smart option. Not only cheap but you don’t have the “oopsie, you are obsolete” issue and cost.

Every other self-tuning device I own has an included microphone and doesn’t require me to keep buying or borrowing a currently supported and far too expensive third-party device. A $50 - $100 USB mike would have saved me money already, more when I buy my replacement and even more when I have to replace the replacement. Sure wish Sonos would look into this option.

I also used my iPod touch several times over the past 6 months of ownership, as I moved things around a bit and also bought a couple of new speakers. I did like that fact I could re-jig my stuff and just re-do the Trueplay if I wanted to. I got the iPod second hand at a cheap price and luckily have just sold it for just £10 less than I paid for it so not too bad. Will miss having it though as it was my little Trueplay device. 

It wouldn’t surprise me if eventually Sonos comes up with another solution to Trueplay, as it seems iDevices will continue to be released once or twice a year (or thereabouts) for a good many years still to come and it must be quite a costly exercise having to calibrate each different Apple product - I did wonder if the Roam microphones might somehow be utilised in some way to gather room data, which in turn could be ‘translated’ and applied to a selected Sonos ‘room’, to maybe help reduce costs?

I guess these things though are always much easier said, than done.

I agree @Ken_Griffiths - I honestly didn’t think about the iPod I had becoming useless for Trueplay so easily (silly of me I guess)

Wish they could come up with another solution

While I’m not sure how practical this scheme might be, it would be possible to present a phone/pad at a properly equipped store/center and have it calibrated. There would be an investment for the calibration equipment and fees for each procedure along with arguments over who should support this effort. Current iDevice users would grumble that this capability had always been free. There would be an argument that retail stores should support this as an excuse to have bodies come through the store, especially if the SONOS purchase was online, but this is only a one time per phone/pad activity. It would be logical to present the phone/pad to retail staff at the time of a SONOS purchase, but this does not factor well in a pandemic riddled world.

If a small little dongle could be produced and sold on a large enough scale, it could probably be priced in the $50.00 range, but would SONOS owners feel that this was fair for something that had been free?

Enquiring minds want to know.

What’s this strange concept: a “retail store”?

I don’t think I’ve been near anything like that, at least for electronics purchases, in years.

With my old Marantz a free microphone (wired) was supplied with the receiver.
