How to Turn On Sony SRS XB33

We explain how to turn on the Sony SRS XB33 portable speaker here.  Now most Bluetooth speakers have a Power button that Sony prominently places on the unit so it’s easy to find.  Indeed, this speaker is no exception, as we find its Power button on the top, as we see next.

There’s also a Power lamp, just behind the Power button, that glows green any time the speaker is running.

Now we also have the Bluetooth status light, that begins flashing or glowing blue when the speaker powers up, as we point out below.

Note that all lamps with the possible exception of the CHARGE light are dark when the SRS XB33 is OFF.

How to Turn On the Sony SRS XB33

To power up the XB33, press the Power button. Then release it after a quarter second or so.  Also, you needn’t hold it in for much time for the unit to see your press and then turn itself on.

Next, when the speaker boots, the Bluetooth status lamp starts blinking or glowing, and the unit may or may not beep.  It will sound a ding-dong sort of beep pattern if it pairs to a nearby BT device.  But if it pairs with nothing, then it makes no sound.

But if pressing the Power button does not turn on the SRS XB33, or if the CHARGE light blinks orange, it could be that you need to recharge your speaker.

So if the unit won’t come on, try connecting a USB charger to it.  Yes, you can indeed play the speaker as it charges.

Now with a charger supplying power, this speaker should always power on when you click the Power button.  If not, then the unit may not be getting any juice from your AC adapter.  So check that the receptacle for the power supply is hot, that the adapter works, that the cable between it and the SRS XB33 is not damaged, and that the charger plug is fully seated in the speaker’s USB-C input port.

But if after all these checks the speaker still does not turn on, then the unit itself may be faulty. So in that case, get a new one.
