She's right.
But it depends how sonically snobbish you are. I am. I'd prefer nothing, LOL. But you might find it sounds better than a little radio etc.
A few possibilities if you can be arsed:
Bose mini cube speakers (tiny) situated under the cupboard units (virtually hidden); bass box hidden in cupboard / ceiling void. NOT the ultimate sound quality but perfectly acceptable for background sound if you don't dig organ music. I've done this in our place.
In-ceiling speakers (flush) only if you're pulling carpet / lifting floorboards above (quality from medium to high)
Drill through shared wall with living room (if this is how your house / hifi is positioned), position one speaker there, and then run 'invisible' speaker tape across wall and overpaint. (quality from medium to high)
I suppose all this makes you even more determined to get your wireless speakers, LOL.
