If you’ve recently purchased a pair of Onn Party Bluetooth speakers, you’re probably excited to crank up the volume and experience stereo sound. One of the standout features of these speakers is the ability to pair two of them together wirelessly, giving you a wider soundstage and a much more immersive listening experience.
In this comprehensive guide, we’ll walk you through everything you need to know about connecting two Onn Party speakers together. Whether you’re prepping for a backyard party, a camping trip, or just want better sound at home, this guide will help you get set up in minutes.
Let’s dive in.

Understanding Onn Party Speaker Pairing (True Wireless Stereo Mode)
Many Onn Party speaker models come with a feature called True Wireless Stereo, or TWS for short. This feature allows two speakers to connect to each other wirelessly. Once paired, one speaker becomes the “primary” speaker (also called the host or master), and the other acts as the secondary (or slave) speaker. You then connect your phone or Bluetooth device to the primary speaker, and both units play audio simultaneously in perfect sync.
This setup can greatly enhance your audio experience, offering richer sound, louder volume, and even stereo separation if supported by the speaker model.
What You Need to Know Before Pairing
Before you begin, make sure you have the following:
- Two compatible Onn Party Bluetooth speakers (models that support TWS or Party Sync)
- Both speakers are fully charged or plugged into power
- Your phone or Bluetooth-enabled device is nearby
- You’re in a location with minimal wireless interference
Not all Onn speakers support TWS, so it’s a good idea to check your speaker’s user manual or product listing to ensure it has the feature.
Now let’s go step by step.
Step 1: Power On Both Onn Speakers
The first step is straightforward—power on both of your speakers.
- Press the Power button on each speaker.
- Wait for the LED light to turn on and start blinking. The blinking blue light usually indicates that the speaker is in Bluetooth pairing mode.
If one or both of your speakers have previously been paired to a device, they may try to reconnect automatically. If this happens, you may need to disconnect them from any previously connected devices before continuing.
Step 2: Initiate Speaker-to-Speaker Pairing (TWS Mode)
Now it’s time to link the two Onn speakers together using TWS mode.
- Choose one speaker to act as the primary speaker. This will be the speaker you ultimately connect to your phone or tablet.
- On the primary speaker, press and hold the Bluetooth or TWS button for a few seconds. Depending on your model, this button may be labeled “Bluetooth,” “Link,” or “TWS.”
- After holding the button, you should hear a beep or tone, and the LED will begin to flash more rapidly or change color (this varies slightly by model).
- Now, go to the second speaker, and repeat the same process—press and hold the same button until it starts looking for the first speaker.
- After a few moments, the two speakers should detect each other and pair automatically.
You’ll usually hear a confirmation chime or tone, and the LED lights on one of the speakers may stop flashing and stay solid, indicating that it’s now connected to the other speaker.
At this point, your two speakers are linked together and ready for Bluetooth audio input.
Step 3: Connect Your Phone or Bluetooth Device
Once the two speakers are successfully paired in TWS mode, the next step is to connect your phone, tablet, or computer to the primary speaker.
- Open the Bluetooth settings on your phone or Bluetooth-enabled device.
- Look for the name of your Onn speaker in the list of available devices. It will typically show up as something like “onn. Party Speaker” or similar.
- Tap the speaker name to connect. Once connected, you may hear a voice prompt or tone confirming the connection.
Now, when you play music or any audio from your device, it should come out of both speakers simultaneously.
Step 4: Enjoy Dual Speaker Sound
With both speakers now connected, you can enjoy a fuller, more immersive audio experience.
Depending on your specific speaker model, the two speakers may play in mono (both producing the same sound), or in stereo mode (where one speaker handles the left audio channel and the other handles the right). Stereo mode creates a more natural and spacious sound, ideal for music, movies, or even gaming.
You can control the volume using your connected device or directly on the speakers. If your speakers support it, the volume buttons may sync, so changing the volume on one speaker adjusts the sound on both.
Optional: Disconnecting or Resetting the Speakers
If you want to disconnect the two Onn Party speakers or switch back to using a single speaker, there are a couple of ways to do it.
Method 1: Power Off One Speaker
Simply turn off one of the speakers. This will break the TWS link and leave the remaining speaker active. You can then reconnect your Bluetooth device directly to the single speaker.
Method 2: Reset TWS Mode
You can also press and hold the Bluetooth or TWS button again on one or both speakers to reset the TWS pairing. This will unpair the two speakers and return them to individual Bluetooth mode.
If your speakers seem stuck or won’t pair correctly, it may help to:
- Unpair them in your Bluetooth settings
- Perform a factory reset (check your user manual for the correct button combination)
- Start the pairing process from scratch
Troubleshooting Tips
Sometimes, pairing two speakers doesn’t go as smoothly as expected. Here are some common issues and how to fix them:
Problem: The speakers won’t pair with each other.
- Make sure both speakers support TWS mode.
- Ensure both speakers are in Bluetooth pairing mode.
- Try moving the speakers closer together.
- Restart both speakers and try the process again.
Problem: Only one speaker plays sound.
- Double-check that both speakers are paired together before connecting to your phone.
- Disconnect your device and try reconnecting only after TWS pairing is complete.
Problem: The sound is out of sync or delayed.
- Ensure both speakers are within a reasonable distance (under 30 feet).
- Avoid interference from other wireless devices or Wi-Fi routers.
- Reset both speakers and try again.
Final Thoughts
Pairing two Onn Party Bluetooth speakers together is a great way to elevate your audio experience. Whether you’re listening to your favorite playlist at a party, watching movies outdoors, or just enjoying music at home, the added volume and stereo effect can make a big difference.
With just a few button presses, you can connect your speakers in TWS mode and enjoy synchronized sound across both units. As long as you follow the steps outlined above and ensure compatibility, the process is quick and straightforward.
If you ever run into issues, a simple reset usually resolves most pairing problems. And once connected, you’ll wonder how you ever listened to music on just one speaker.
