I've been on the lookout for some of these for a while - cheapest I've found is around the £150 mark but I've just bought two from Curry's for under £210 using the bundle option on the page. These can be used as standalone items or for providing surround sound with certain Samsung soundbars/setups. Great for multiroom streaming setups via deezer/spotify etc using the samsung multiroom app. These have reviewed generally well and are much cheaper than sonos etc equivalents.
Seems a great deal to me!
