Summary: It seems I am yet another person who has been sent the US version in the UK, the 2 pin plug and 120v is a bit of a give away. Not very happy, as I understand it is illegal to sell items without the correct plug in the UK, and also it is a potential fire hazard as if I had plugged in it with a travel adaptor they may have blown. Be warned if you are purchasing these in the UK you may not get the correct model (a replacement is not available only a refund.
Summary: The first thing that I noticed was that the item did not have a UK electrical plug. My understanding is that it is illegal to sell electrical appliances without the appropriate national plug. I changed it over for a normal UK three pin plug and tried to use it. No power was going to the appliance. I tired to use the Amazon returns process but it would not accept it as a return and a request for a replacement.
Summary: As other have said, these speakers arrived with the seal broken and the jack cable missing. The electric plug was not meant for the UK, it was a two pin plug meant for the USA and the rating on the speakers stated 120V. So they are going straight back. Why sell them in the UK for the UK market if they aren't appropriate? Most annoying, I hope I get my full refund ASAP. If I could pick zero stars I would.
Summary: The ones that arrived for me do not have a UK 3-pin plug, instead they have the American 2-pin plug. I don't know whether this is standard but it sounds like I was sent out the wrong item. Have had to buy an adapter for them to work. Another note is that the security seal had already been broken so they were not even new.
Summary: I find it completely absurd that any supplier thinks it acceptable that a product ordered in the UK from a UK supply depot and delivered to a UK purchaser at a UK address comes with a moulded on flat two pin mains plug (american style I think) which is of no earthly use to me at all. I cannot comment on the quality of the product itself as I can't plug it in to try it out and consequently it has been sent straight back for a refund.
