This post shows how to connect a wireless Sony speaker to an iPhone smart phone. Doing so gives you a much bigger, and arguably better sound when you stream music from the iPhone to speakers like these.
How to Connect Sony Wireless Speaker to iPhone, Step by Step
With your speaker switched OFF (power button is dark), run through these directions to connect it to your iPhone mobile device. For this demo, we use an iPhone 12 Pro Max and the Sony SRS XB43 Bluetooth speaker.
1. Go to the Home Screen on your Smart Device
Firstly, press and release the side button (right edge of the phone) and enter your passcode or Face Id to bring up the Home screen.
2. Find the Settings App
We found ours on the second page of the Home screen, as shown next.

3. Bring up the Settings App
Thirdly, tap the Settings app icon.
The smart device then shows the first page of its settings, as shown in the next step.

4. Go to the Bluetooth Option to Continue with How to Connect Sony Wireless Speaker to iPhone
Tap the Bluetooth item on the Settings page.
Then you get the Bluetooth Settings screen, as we show next.

Note that our Bluetooth is running here. But since our test Sony wireless speaker (the XB43) is currently shut OFF (is not in pairing mode), it does not show up in the BT devices list. Also, we don’t see it since we’ve never paired this speaker with this iPhone before.
5. Turn On your Speaker
Turn on the BT speaker by quickly pressing its Power button. See this, pointed at by the green arrow, in the next picture.

The speaker then powers up, and its status lamp glows, as seen in the next picture.

Also, the BT lamp will blink in some pattern to indicate that the speaker is ready to receive a pairing request, as we see in the next picture.

If it blinks evenly, then it’s passively waiting for a wireless connection request to come in.
But if it fast flashes or blinks in a pulse-pulse-pause, pulse-pulse-pause pattern, then it’s broadcasting its discovery information over the airwaves so other devices can find it. I.e. The speaker is in discovery mode in this case.
Moreover, since our test iPhone does not know about this speaker, this Sony wireless speaker will not pair with it automatically.
6. Put the Sony Wireless Speaker into Pairing Mode
Now, to see this speaker on your iPhone, place it into pairing mode if it’s not in that mode already. To do that, press the Pairing button, and release when the unit beeps or speaks that it’s in pairing mode, and the Pairing Status lamp begins its rapid or pulse-pulse-pause, pulse-pulse-pause flashing pattern, as we see in the last picture.
7. Find the Speaker on your Phone to Continue with How to Connect Sony Wireless Speaker to iPhone
See the screen shot next. We found our speaker, as we point out with the green arrow.

8. Connect with your Sony Wireless Speaker
Tap the listed speaker in the Other Devices list.
The iPhone then connects with the test speaker here.
I.e. The iPhone’s Wireless Settings screen might then change to look something like the following. Note the now-connected Sony SRS XB43 entry, as we point out with the green arrow in the next screenshot.

9. Done with How to Connect Sony Wireless speaker to iPhone !
At last, we have now successfully connected the test speaker with a popular iPhone.
