How to Link Bose Speakers

Linking Bose speakers is done in the Bose app, and which linking mode is available depends on whether your speakers are identical. Two of the same model can form a stereo pair, one taking the left channel and one the right. Different models can play the same audio together in party mode, but cannot form a stereo pair, because stereo requires matched drivers.

Getting this right starts with knowing which app your speakers use.

Which app you need

Bose has used several apps and the products are split between them.

The Bose app covers most current portable speakers, headphones and recent soundbars.

The Bose Music app covers the smart speaker and soundbar family, including the Home Speaker range.

The older SoundTouch app covers the SoundTouch multi-room products, which are a separate system entirely.

Products on different apps generally cannot be linked to each other. A SoundTouch speaker and a portable SoundLink are not part of the same system, and no amount of pairing attempts will change that.

Check which app your model uses before starting, since half the frustration in this area comes from trying to link products that were never designed to link.

Party mode and stereo mode

Two portable speakers connect to each other, and there are two ways they can behave.

Party mode plays the same full audio through both speakers. Any two compatible Bose portables can do this, including different models. It is for coverage, putting sound in two areas.

Stereo mode sends the left channel to one speaker and the right to the other, which recreates the stereo image the recording was mixed with. This requires two speakers of the same model, because the two channels must be reproduced identically for the image to hold.

Stereo mode is the better sounding of the two by a wide margin if you sit between the speakers, and worse if you are walking around, since you only hear half the mix from each.

Party mode is the right choice for a garden or a party. Stereo mode is the right choice for a room where you sit down.

Linking two portable speakers

1. Charge both speakers and turn them on.
2. Connect your phone to one of them over Bluetooth. This one becomes the source.
3. Open the Bose app and select that speaker.
4. Find the party mode or connect option, often under a speaker icon or in the settings for the speaker.
5. Select the second speaker when it appears in the list.
6. Once linked, switch to stereo mode if both are the same model and you want it.

On several models this can be done without the app by holding the Bluetooth button on both speakers until they find each other, though the app is more reliable and gives you the stereo option.

Both speakers should be running current firmware. Mismatched firmware between two identical speakers is a common cause of linking failing for no visible reason, and the app updates them.

Linking smart speakers and soundbars

The Home Speaker and smart soundbar family work differently, over Wi-Fi rather than Bluetooth.

Add each product to the Bose Music app individually first, assigning it to a room.

Once several are on the same network and account, they can be grouped, and a group plays the same audio in sync across rooms.

Two identical smart speakers can be made a stereo pair within one room, and a compatible speaker pair can act as rear surrounds for a Bose soundbar.

All products in a group must be on the same Wi-Fi network. A speaker that has joined a guest network or a separate band on a mesh system will not appear, and this is the most common reason a product is missing from the list.

SimpleSync

SimpleSync is the feature that links different categories of Bose product together, and it is worth knowing about because it solves a specific problem.

It lets you play the same audio through a Bose soundbar and a pair of Bose headphones at the same time, or through a soundbar and a portable speaker.

The use case is genuine: watching television at a volume that suits the room while one person listens through headphones at their own level, with independent volume control on each.

It works within supported product families, so check whether your specific soundbar and headphones both support it before relying on it.

There is a small latency difference between the two outputs on some combinations, which matters for video and not for music.

When linking fails

Confirm both products use the same app and are in the same product family.

Update the firmware on both, since version mismatches break linking silently.

Confirm both are on the same Wi-Fi network and band for smart products.

Forget the Bluetooth connection on your phone and reconnect, since a stale pairing record is a frequent cause.

Clear the speaker’s paired device list if it has connected to many devices, which fills a limited memory on some models.

Move the speakers closer to each other during setup, then separate them once linked.

Reset the speaker as a last resort, which clears its memory and requires setting up from the start. Our guide on resetting Bose products covers the sequences.

Placement for a stereo pair

Getting this right matters more than which mode you chose.

Space the two speakers roughly as far apart as you sit from them, forming a triangle.

Get them to ear height when seated, since treble is directional and speakers at knee level lose detail.

Keep them symmetrical relative to the side walls, because asymmetry shifts the stereo image sideways in a way no setting corrects.

Check the left and right assignment in the app matches their physical positions, since the app assigns channels and does not know where you put them.

Frequently asked questions

How do I link two Bose speakers?

Connect your phone by Bluetooth to one speaker, open the Bose app, select that speaker, and use the party mode or connect option to add the second. On many models you can also hold the Bluetooth button on both until they find each other, though the app is more reliable and offers stereo mode.

Can I pair two different Bose speakers together?

In party mode, usually yes, provided both are in the same product family and use the same app. In stereo mode, no. Stereo mode requires two speakers of the same model, because the left and right channels have to be reproduced identically for the stereo image to hold together.

What is the difference between party mode and stereo mode?

Party mode plays the full audio through both speakers, which suits covering two areas. Stereo mode sends the left channel to one and the right to the other, which sounds considerably better if you sit between them and worse if you are moving around, since each speaker carries only half the mix.

Why won’t my Bose speakers connect to each other?

Most often they are on different apps or product families, or their firmware versions do not match. Update both in the app first. For smart speakers, confirm they are on the same Wi-Fi network, since a speaker that joined a guest network or a different mesh band will not appear in the list.
