This post shows how to connect a Sony SRS XG300 boombox speaker to an iPhone smart phone. Doing so gives you a much bigger, and clearly better sound when you stream music from the iPhone to speakers like this one.
How to Connect Sony SRS XG300 to iPhone: Step by Step
With your 300 switched OFF (power button is dark), run through this routine to connect it to your iPhone.
1. Go to the Home Screen on the iPhone
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
Next, flip through the Home screen pages until you find the Settings app. We found ours on the second page of the Home screen.

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 SRS XG300 to iPhone
Tap the Bluetooth item on the Settings page.
Then you get the Bluetooth Settings screen.

Note that our Bluetooth is running here. But since our test XG300 speaker is currently shut OFF (is not in Bluetooth 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 XG300
Turn on the 300 by quickly pressing its Power button. See this, pointed at by the pink arrow, in the next picture. Find it on the top of the unit, closest to the left edge.

The speaker then powers up, and its status lamp glows.

Also, the Bluetooth lamp will blink in some pattern to indicate that the speaker is ready to receive a Bluetooth pairing request.

If it blinks evenly, then it’s passively waiting for a Bluetooth connection request to come in.
But if it blinks in a pulse-pulse-pause, pulse-pulse-pause pattern (double flashing), then it’s broadcasting its pairing information over Bluetooth so other devices can find it. I.e. The speaker is in pairing mode in this case.
Moreover, since our test iPhone does not know about this speaker, this Sony SRS XG300 boombox will not pair with it automatically.
6. Make Sure the XG300 is in Pairing Mode
Now, to see this speaker on your iPhone, place it into Bluetooth pairing mode if it’s not in that mode already. To do that, press the Pairing button. Then release it when the unit beeps and speaks that it’s in pairing mode. Also, the Bluetooth Status lamp begins its rapid or pulse-pulse-pause, pulse-pulse-pause flashing pattern, as we see in the last picture.
Find the Pairing button on the top button panel, second button from the left.

7. Find the Speaker on your Phone to Continue with How to Connect Sony SRS XG300 to iPhone
See the screen shot next.

8. Connect with your XG300
Tap the listed speaker in the Other Devices list.
The iPhone then pairs with the 300 here.
I.e. The iPhone’s Bluetooth Settings screen might then change to look something like the following. Note the now-paired Sony SRS XG300 entry.

9. Done with How to Connect Sony SRS XG300 to iPhone !
At last, we have now successfully connected the XG300 with a popular iPhone. So you may now play music and videos on the phone, and the sound for them will play on the speaker. Enjoy !
