The rich and full sound (including bass) that comes out of these speakers is extraordinary! I was stunned at how good this thing is when hearing it for the first time. 3D sound, along with an 'outside' feature which decreases the lows, and increases the highs for longer distance hearing if desired. I almost bought the next biggest Wonderboom 3, but one of the MAIN reasons I got this one is because of the utility loop attached to it. Which incidentally is my last point of this review, one of my favorite features is the ability to hang this speaker above you when listening, it's incredible compared to just setting it on a table for example. You can also sync 2 Wonderboom 3's for even better fidelity, will definitely be buying a 2nd one.
