Sonos Sub Gen 3 crackling/static sound

Hi guys, I have some terrible news.

I received my replacement from Sonos yesterday. Excellent customer service, quick turnaround with the replacement, but all the great service doesn't change the fact that the new unit is the same as before. Which leads me to conclude that it’s a design flaw.

Now why is this apparent flaw not bigger news online that it currently is? Because not everyone will be capable of hearing the noise. I wouldn't call myself an audiophile in any way, but the noise is obvious to me, making it irksome, my partner says he can’t hear it unless she’s 1 foot away.

I assume that many people will be blissfully unaware of this flaw, until someone with more attuned hearing points it out the them, and then it becomes something you can’t un-hear.

The bass that comes out of the Gen 3 sub is rich, deep and everything you’d want it to be. Unfortunately for me, the electro-static ticking noise, ruins the enjoyment I should be getting out of this £699 premium product.

Am still a Sonos fan, just a little less than I was before.

Well that’s disappointing, what’s funny is I had bought a Gen 2 sub originally with my new Sonos arc since the gen 2 was on sale for $150 off at Best Buy but then quickly decided I’d rather spend more and invest in the gen 3 for future proofing and updates.  The gen 2 had no issues and sounded the same to me despite the gen 3 having updated internals.  May just return the gen 3 now and grab the gen 2 and save that $150 again.  I’m probably being really picky because I really can only hear the noise if I get very close to the sub but once you know about it, you can’t forgot it or Unhear it and it makes  me a little upset that a product at this price and the new generation at that has an issue when the previous gen at less money is perfect,  

They sent me a replacement but it was refurbished Gen 2 sub instead LOL! back to Sonos support, what a nightmare, bit disappointed with this, mistakes happen but a bit frustrating when you're spending this kind of money.

Was it Best Buy or Sonos that sent the replacement?

It was Sonos Support.

Just wanted to note from Andrew and I’s cases, evidence points to this being a hardware issue and Sonos says a fix isn’t available yet. Wouldn’t advise a replacement unit because nothing will change. Call Sonos and cite Andrew’s case number and they’ll link the issue to your case. We can get more traction on the problem and you’ll have your situation documented and on file.

I have one on order… is this affecting all of them? If so I might just cancel for now and wait until this is resolved?

I don't think it's everyone, Peter Pee a Youtuber who focuses on reviewing and testing Sonos products said he’s not hearing this noise on any of his subs, so may not be widespread issue.

I’m not experiencing this problem.  If I put my ear right up against the top of the sub, I think I hear an extremely faint “whining” noise.  It’s barely audible.  I hear nothing if I put my ear in front of the sub’s opening and nothing while I’m standing near it.  So either I don’t have the problem or my hearing is just that shot ;-)

I just canceled my gen 3 order, not really overly concerned with the issue but Best Buy has the gen 2 now versus waiting until August sometime and it’s a good chunk cheaper.
