How to Connect Harman Kardon Speakers to iPhone, Step by Step
Using the Invoke speaker for this demo, we note that this particular unit has no Power button. In fact, it has no batteries, and runs exclusively on AC power. So to power up this particular speaker, you just plug it in.

1. Bring Up the Home Screen on the iPhone
At the lock screen, swipe up from the bottom to bring up the phone’s Home screen, or press the Home button if your phone is older.
2. Find the Settings App
We found ours on the second page of the home screen, shown next.

3. Bring up the Settings App
Tap the Settings app icon.

The phone then displays the first page of its settings, as we see.
4. Go to the Bluetooth Page to Continue with How to Connect Harman Kardon Speakers to iPhone
Tap the Bluetooth item. Our Bluetooth screen then displays, similar to the following.

Note that our Bluetooth is enabled here. If yours shows as OFF, then move the switch item to the ON position as ours is in the last picture.
Now since our test Harman Kardon speaker (the Invoke model in this scenario) is currently not in pairing mode, it does not show up in the Bluetooth devices list. Also, we don’t see it since we’ve never paired this speaker with this iPhone before.
5. Turn On your Bluetooth Speaker
Now if you haven’t done this already, plug your speaker into AC power. It then boots and the light on the top glows in various patterns.

The speaker then powers up and makes some sort of power-on sound after about a minute. Then the light island goes dark and the speaker is now ready to accept incoming pairing requests from source devices.
But since the iPhone does not know about this speaker, the phone will not pair with the speaker automatically. The Pairing button denotes this not-paired state by either remaining dark, or by flashing.

6. Put your Harman Kardon Speakers into Pairing Mode
Now, to see your speaker on your mobile device, place the speaker into pairing mode. To do that, press and release the Pairing button, located on the back near the bottom of this particular speaker..

Thee speaker then plays another, but different, rising notes sound, and the Pairing button starts fast blinking white.
7. Find your BT Speaker on your Mobile Device to Continue with How to Connect Harman Kardon Speakers to iPhone
See the screen shot next. We found our speaker, as pointed at by the dark blue arrow.

8. Next, Connect with your Speaker
Tap the listed speaker in the Other Devices section of the BT devices list.
Your iPhone then connects with the speaker (named “HK Invoke_C33656” in this scenario). The mobile device’s Bluetooth screen then changes to look something like the following.

Typical Harman Kardon speakers like the Invoke plays a set of notes to let you know that pairing mode has begun.
9. Done with How to Connect Harman Kardon Speakers to an iPhone !
AT last, we have now successfully linked this BT speaker. Similar routines work with pairing iPod Touch players, iPad Pros, and any iPhones as well so long as they support Bluetooth. Pairing with Android devices works like this too.
