Wireless speakers

Hi,

Now i'm enjoying the music with my hi-fi I would like more music around the flat.  I would want wireless speakers in the summerhouse and patio area and also in the bedroom.

Usual problem is that the other half won't want large speakers so I have been looking at the below:

These kind of fit the bill, price, size and look ok.  I know the sound wont be outstanding but the reviews seem ok.

Has anyone got these or have heard them or could advise of any other options.

I have looked at the JBL wireless option but they are expensive and don't have the option to run just on batteries.

Thanks,
