Sounds like you were not shipped the right cord.  Can you post a picture to confirm?  Sonos monitors these threads and would be able to confirm as well as other customers.

There’s really only the one L shaped cord that comes from us. It is a snug fit, so my advice would be to push harder. But if it’s really not going to work, you can contact our support team directly and they can probably send out new cords or replace the unit.

Thanks for your replies.

It looks like it’s the right cord, L-shaped, same configuration-it’s just very tight. I’ll try again and if it still doesn’t fit I’ll contact the support team.

OK, thanks again. The cord fits, I just had to lean into it with some bodyweight.

You wait till you need to remove it!

I learned to use a very light touch (not spray) of dry (just leaves a powder, not oily coating) silicone lubricant to ease the cord insertion process and if ever needed I sure hope the removal process too.

Hi looks Like I have the same problem and been sent the wrong cord. Can someone confirm ? 

You evidently have a Sub gen 2, with the cord for a Sub gen 3.

Thanks for that. Just bought it from Curry’s PC World today 

It looks like your cable has a thin, circular flange, which is designed to go flush into a circular recess on the body of the product. That’s a cable for the later Sonos products: Beam, Amp … and Sub gen 3.

A Sub gen 2 needs a cable like this: https://www.sonos.com/shop/power-cables-sub.html

You’d better go and sort it out with Curry’s.

I have the same issue: The power cord does not fit in place on my Sonos One. The most likely cause is a manufacturing defect in the cord. I believe the end that plugs into the Sonos One is about 1/8" too long. As a result, the cord is not fully seated and the Sonos One cannot sit flat. It does receive power.

I believe I could file the end of the cord by 1/8" and the One would work fine, but I wanted to ask first.

I would try pushing it harder.

The Sonos One does not have a power cord like pictured above. It is L shaped, so when it is seated fully, the Sonos One sits flat on the surface. There have been a handful of posts suggesting that getting it properly seated requires more force than expected, as John B suggests, but none, so far, that haven’t finally seated properly, or even any shipped with an incorrect cable, as the Subs above were. 

I put a little silicone on the cord. I pushed hard. It still would not go.

I used a rubber mallet and gentle tapped the cord into place. All set now!

Thank you for your tip.

Sounds like perhaps the factory didn’t remove all the extra ‘flashing’ on the cable. Glad you got it seated. 
 

I think I’ve only removed the power cables from a speaker when swapping them out...I mounted some speakers on a wall, and didn’t want a full length cable. On most of my speakers, I’ve never removed the power cord, ever. If you need to do so, a pair of pliers would likely be helpful to get a grip, but I doubt you’ll need to ever do it. 

I just purchased 2 Sono One speakers and the power cords do not fit securely in the bottom of the unit. When I pick up the speaker, they fall out s bit. Also when they are plugged in, the speaker is lifted on one end by the cord.  Any help or suggestions?

So, reading that, I’ve got two thoughts. 
First, can you confirm that the cords you received have an L shaped end that plugs in to the speaker, and isn’t just a straight cable?

If indeed it is L shaped, I think, based on your ‘lifted on one end’ comment that they’re not properly seated. There have been other folks who have found the seating of these cables to be difficult. When properly seated, the cable should be flat with the bottom of the speaker. I wonder if there’s any excess ‘flashing’ around the connector that is getting in the way of upyou seating the cable properly.

I’d certainly try pushing the cable in more firmly. 

I have pushed really hard and yes it is L shaped. One person on here used a rubber mallet but I am afraid I will damage the connection  

Pull it back out, and check to see that there isn’t any extra flashing around the plug that might be getting in the way. Or in the receptacle, although I don’t recall any potential there. Wouldn’t hurt to look. In all honesty, I think in the last 5 years, I’ve never unplugged a PLAY:1 or a Sonos One. Once I’ve inserted that cable, it’s just in. Tightly, so it doesn’t slip out, but not as tightly as it looks like you are experiencing. 

But that is the correct cable. And it’s supposed to end up flush with the bottom of the speaker. Since you’re the second or third person to report this in the last six months, I wonder if there might be a manufacturing issue. If you want to, you might call Sonos Support directly to discuss it, to see if they’d send you a replacement cable. 

Thanks . I think I will try a rubber mallet first before I call them.

The rubber mallet worked and it is now flush and secure. I hope this helps some one else.

Glad it worked. Doesn’t seem right, but as I say, unlikely you’ll need to pull it out any time soon. 

It seems to be the norm with sonos units. I thought that my beam was faulty because the power supply would disconnect from the sonos beam and was always a bit wobbly. I took it back to point of purchase and the guy just pushed it in HARDER than you would and like magic it no longer disconnects or is wobbly at all . I walked into JB HIFI 6 feet tall and left feeling about 2.4 feet .

We all have instances of that kind of thing. With me, probably more than average :)

This is exactly the same issue I am having.
