Brand new unused Sonos Arc soundbar. I bought this as you can see from the receipt in a 40% off sale in the states which was too good to not take full advantage of! (I have the full receipt unredacted for the winner to see if they so wish). All Sonos products are 110-240V so they're all compatible, I buy all my kit there. It comes with international warranty (see below)  I took it out of the box to get it through customs in the UK, I never checked it in, it came with me in the cabin (First class!) in plain packaging. I am in the middle of building work so it's been in my cupboard since I bought it but now my project has evolved into a full actual home cinema I have no real need for it and I need the money it makes to pay for the cinema kit now! It comes with the power cord which I have put a UK plug on. No wall bracket included. It’s still in its original felt sleeve and I will get it boxed & bubble wrapped & insured securely for postage.
