Any Bluetooth wireless speakers that you like?

Yes, passive radiator as seen in the rear as well.

This was the most hifi I have heard a Bluetooth speaker sound to-date and for much less than the other leading contenders.

Big fan of the HK Onyx 2. I've auditioned several bluetooth speakers and this one was the best. Plays loud. Has warmth and punch in the bass. Has good midrange and treble detail and has outstanding tone. Never irritating or annoying. Never. It's kind of like a Vandersteen bluetooth speaker. Gets better after about 50 hours of play.

Gd my impressions were similar.    Ue boom2 sounded like a toy in comparison and would have cost 33% more.   Great price on Amazon.  Should arrive tomorrow.  Looking forward to it. 

Yes, I got it Friday one week ago.

I am very happy with it. The best single speaker Bluetooth sound I have heard to date especially for the $150 it ended up costing. I can easily recommend it at that price point.

Ironically now my wife wants me dump my wired speakers in her sunroom for it. The HK sound is good enough that I might not miss them too much in there if it comes to that in that the sound quality is very good especially for its size and I’d still have my high end wired setups in three other rooms.

Lots of full extended good quality bass, a slight lovely warmth in the midrange clean highs, nicely balanced top to botto, good dynamics and goes pretty loud with no noticeable breakup or distortion.

Imaging and soundstage is not much there with a single speaker but I have that in spades elsewhere so not a big issue.

A very nice addition for a well set audiophile looking to explore portable blue tooth sound without spending a lot.
