How to Make Sony XB 33 Discoverable

To pair your XB 33 Sony Extra Bass speaker with a Bluetooth device for the first time, or to refresh stale linkage data in that device, you need to understand how to start up discovery mode on this portable speaker. Now in discovery mode, the speaker digitally announces its name and connection information over Bluetooth, so that nearby devices can find and join with it. Then once connected, the source device can stream audio to the speaker, which apparently is something that so many like to do. So in this post, we show you how to make the Sony XB 33 discoverable, to let you link it with phones, tablets, computers, and smart speakers.

How to Make Sony XB 33 Discoverable, Step by Step Guide

1. Turn On the XB 33

Firstly, turn on the speaker by rapidly pressing and releasing its Power button.

E.g. See this button, pointed out by the yellow arrow, in the next picture.

The speaker then starts up.

Now if the speaker has never connected with a device since its last reset, then it automatically becomes discoverable. But if it has paired with a phone or other mobile device since the last reset, then you must manually put it in discovery mode.

2. Press and Release the Pairing Button After a Half Second

Secondly, to do that, you press and release the Bluetooth Pairing button. E.g. See the location of this button in the next picture. You needn’t press it for long for the action to register.

The speaker then announces “Bluetooth pairing…” in a female voice. So at this point, the unit is now discoverable by other Bluetooth devices.

Note also that putting the speaker in discovery mode does not clear its prior stored BT links. It just allows you to connect to and add new devices to its memory, but does not delete any.

Now if the speaker is misbehaving and will not go into discovery mode, you can try resetting it and see if that solves the problem. We describe that process in our How to Reset Sony XB 33 Wireless Speaker post.

Finally, while the Bluetooth Status lamp is fast blinking, you should see the XB 33 on any in-range phone, computer, tablet, or smart speaker, that is within several feet of it, as we see in the last picture. The speaker appears as “SRS-XB33” there.
