Any Bluetooth wireless speakers that you like?

I'm looking to add sound to the living room in a WAF friendly manner.   Gotta be inconspicuous and no wires showing!

I'm thinking a wireless Bluetooth speaker that I can connect to from tablet or Smartphone running my favorite music apps is the way to go.

Any particular good sounding ones that you have heard?

The retro-styled Marshalls would fit in aesthetically I think.  My wife likes retro!  Maybe the portable model.

It turned out to be the Libratone. It's a nice speaker. Sounds way better and bigger than the little Oontz. I would definately consider buying one. It's portable enough since it has a small footprint and a nice carry strap. And it puts out enough sound to make it useful for small get togethers. It's the best combination of functionality, portability and sound that I've heard so far.
that's exactly the UE Boom2 for less money.....
UE Boom 2 appears much smaller and lighter than Libratone. Though similar on concept.  Can't possibly go as loud and clear, can it?

well, i can't say how loud the Liberatone can be but the UE Boom2 can get very loud. My niece owns one & I’ve heard it in action.
It’s not that light - it’s got some weight to it when you pick it up.
I saw that both Walmart & Target have these units on display & you can test it out for yourself volume-wise.....
I heard the ue boom at local Walmart today.    

It it was the best sounding Bluetooth speaker they had there no doubt.  It was playing in a huge store but I thought it a tad small for my purpose.   It did have nice build quailty and sound for the size.   Also the priciest model at Walmart.  A few others were larger but very Lo fi.  I heard the $99 flat round ue model at a relatives a while back and was very impressed with the sound and build quality. 
mapman, glad that you auditioned the UE Boom2. I'm in agreement with you re. the build quality, modern looks, size & quality of sound. 
My Walmart has the Bose Soundlink Mini & Soundlink as well - they sound very nice but they are expensive. For the Soundlink Mini which is $199, I'd rather buy the UE Boom2.
is the Liberatone much bigger in size & sound than the UE Boom2? I searched their website but could not find any dimensions. Maybe other users can tell us if it will work for a larger room....
