Sony's new generation of wireless speakers with extra bass sounds even better than before.

  • +

    The SRS-XB33 provides surprisingly rich and good sound for being so compact. The larger XB43 has even more of everything, and also cleaner voices and instruments.

  • -

    The SRS-XB33 sounds a bit flat when forced to play loud, and bass pressure is limited. The SRS-XB43 is too big for the handbag, and although it is more powerful, it is not the difference night and day.

The Sony SRS-XB33 is, in short, the best wireless travel speaker in its class.

  • +

    Impressively full and good sound. Good battery life, several can be connected.

  • -

    The sound may need adjustment before it sounds at its best. Pretty slow charging.

There’s plenty for the Sony SRS-XB33 to shout about, and it isn’t afraid to do so in the most extravagant ways

    Some roughness to treble, Could be more dynamically engaging

I bought one of these two weeks ago to put in my side by side and loved it so much that I bought another one for work. The sound is amazing and I like the equalizer. The lights are also a nice touch.

Nice sound, good base. You can turn the flashing lights off (I did). It's VERY easy to connect to Bluetooth. It's nice that it's water resistant as well.

Just bought this speaker a week ago. I guiltily judged a book by its cover so to speak. It was a reputable brand and the right size and price range so I made the purchase only to be pleasantly surprised. The features and ability to use apps on my phone to get more features added to my surprise.
