My UE Wonderboom (received as a gift last year) stopped working and I jumped on the excuse to find something better (I never cared for the sound). I’ve had a Sony SRS-X5 (@SONY please bring this back!) for years and I hoped to find something with a similar sound, but with more portability.
I was a bit disappointed with the XB23 at first but, after some tinkering in Music Center and speaker placement, I fell in love with this speaker for what it is. I get an impressively warm and rich sound out of this little guy (B+5, M-2, T=0) but only if I keep the volume between 1/3 and ½ on my phone (Galaxy S9). This will work great as a travel speaker on business trips but it’s not something I will take camping, on picnics, or even listen to around the house. I’m thinking of giving the XB33 or XB43 a try to see if they’re better (but those cheesy lights!).
At higher volumes the XB23 sounds tinny and the bas is annoyingly poppy but, and lower volumes, this little guy can produce a really enjoyable sound (the little passive radiators can only handle so much). If you’re looking for something small to keep at lower volumes (like a hotel room) this is perfect. If you’re looking for something to enjoy music outside or with friends, I’d say keep looking. – This is just my two cents and I welcome other’s input. Thanks for reading!
