How To Connect Multiple JBL Speakers Together
By Robert Jones · 2022-06-10
Trying to get your JBL speakers to play together? It's not always straightforward with their different connection types. I'll guide you through JBL Connect, Connect+, and PartyBoost so you can get your tunes cranking.
So, you've got a JBL speaker, maybe two, or even a few knocking about, and you're wondering how to get them all singing together. It's a common query, this one. Folks see "PartyBoost" or "Connect+" on the box and immediately start dreaming of a wall of sound. Well, let's clear up the confusion and get your JBLs playing nice. ### Quick Verdict **Getting JBL speakers to play together is mostly straightforward, but depends entirely on the specific JBL Connect tech they use.** I've had countless people ask me about this down the years. "Robert," they'll say, "I've got this Flip 5 and an old Charge 3, can I link them?" And the answer, more often than not, is "it depends." JBL, bless 'em, have gone through a few iterations of their multi-speaker tech, and they're not all compatible. Bit of a faff, I know, but once you get your head around it, it's simple enough.  *How To Connect Multiple JBL Speakers Together — tested in the SpeakersMag workshop.* ## The Three Main Flavours of JBL Connectivity Right, let's break down the different ways JBL lets you link up their portable speakers. You'll primarily run into three types: JBL Connect, JBL Connect+, and JBL PartyBoost. Think of them as different languages – a speaker using Connect+ can't chat with one using PartyBoost, even if they're both JBL. Makes sense, doesn't it? It's absolutely vital you know which version your speakers support. Usually, it's printed right there on the speaker itself, near the button, or in the manual. If you've binned the manual like most sensible people, a quick Google of your speaker model will tell you. ### 1. JBL Connect This is the old guard, the original. If you've got an older Charge 3, Flip 3, Pulse 2, or Xtreme 1, chances are they're using JBL Connect. This system allows you to link two JBL Connect-enabled speakers for stereo sound or multiple speakers for mono playback. It was pretty clever at the time. To use it, you'd generally press the Connect button on the first speaker (the one connected to your phone), and then on the second. They'd beep or flash, and away you'd go. Simple as chips. **Who it's for:** * Owners of older JBL models like Flip 3, Charge 3, Pulse 2, Xtreme 1. * Anyone needing a basic two-speaker stereo setup. **Who should skip it:** * If you're buying new speakers, this tech is largely obsolete. * If you want to link with newer PartyBoost or Connect+ speakers. ### 2. JBL Connect+ This was JBL's upgrade, designed to allow linking of *up to 100* speakers. Now, who needs 100 portable speakers? I don't know, maybe a seriously massive party. Or someone who just really, really likes JBL. Most people never get past two or three, mind. Connect+ brought better stability and more speakers to the party, hence the "+". Speakers like the Charge 4, Flip 4, Pulse 3, Xtreme 2, Boombox 1, and the older JBL Link series often use Connect+. The process is much the same as Connect: pair your phone to one speaker, then hit the Connect+ button on that speaker, and then on any other Connect+ speakers you want to join in. The JBL Connect app (more on that later) also made managing these connections a bit easier. I remember setting up a Connect+ chain with about eight Flip 4s for a mate's garden party a few years back. It was a right racket, but it worked. The sound was spread out lovely, perfect for keeping the neighbours happy-ish at a reasonable volume. **Who it's for:** * Users with Connect+-enabled speakers (Charge 4, Flip 4, etc.). * Those wanting to link more than two speakers together. * Anyone happy to use the JBL Connect app for easier management. **Who should skip it:** * If your speakers are only Connect or PartyBoost compatible. * If you only ever plan on using one speaker. ### 3. JBL PartyBoost This is the latest and greatest from JBL for their portable line-up. PartyBoost came out with the Flip 5 and is featured on subsequent models like the Charge 5, Flip 6, Pulse 4/5, Xtreme 3, and Boombox 2/3. It's an entirely new protocol, meaning PartyBoost speakers *only* link with other PartyBoost speakers. They won't talk to Connect or Connect+ models. And that's where a lot of people get caught out. PartyBoost also allows for stereo pairing (two speakers) or linking many speakers for mono sound, just like Connect+. The sound quality and stability are generally excellent with PartyBoost. The button usually has an infinity symbol or a chain link icon on it. You connect it up in the same way: link your phone to one speaker, press the PartyBoost button, then press it on the other PartyBoost speakers you want to add. I've had a pair of Charge 5s running PartyBoost in my workshop for months. They make a decent stereo pair, one on each side of the bench. The separation is surprisingly good for portable units. Very handy for drowning out the hum of the soldering iron. **Who it's for:** * Owners of newer JBL speakers (Flip 5/6, Charge 5, Xtreme 3, Boombox 2/3, Pulse 4/5). * Anyone wanting the latest multi-speaker tech from JBL. * Those who value reliable connections and good sound spread. **Who should skip it:** * If you only own older JBL speakers (Connect or Connect+). * If you're not planning on expanding your JBL collection with recent models. ## The Dreaded Incompatibility Trap Here's the bit that catches most folks out. You simply cannot mix and match these technologies. A JBL Charge 3 (Connect) will not link with a JBL Charge 4 (Connect+), and neither of them will link with a JBL Charge 5 (PartyBoost). It's a hard line. Think of it like trying to plug an old analogue phone into a modern fibre optic broadband socket – it just won't work. JBL has moved on, trying to improve the tech with each iteration. While I can see *why* they do it, it does mean that if you've got an older speaker and buy a brand new one, you might be out of luck trying to pair them up. Always check the compatibility of *your specific models* before you get your hopes up or splash out on a new speaker to join an old one. ## Step-by-Step: How to Link Your JBL Speakers Right, let's get down to the nitty-gritty. The general method is pretty consistent across all three technologies, assuming your speakers are compatible. I'll give you the common steps, but remember to refer to your speaker's manual or the JBL Connect app for model-specific nuances. ### 1. Identify Your Speaker's Technology As I mentioned, this is the first and most crucial step. Look for the Connect/Connect+/PartyBoost button on your speaker. It'll have a distinct icon. If you're unsure, check the product page on the JBL website or a quick search online for "[Your Speaker Model] JBL Connect type". ### 2. Fully Charge Your Speakers Always a good idea. Low battery can cause dodgy connections or cut-outs. Don't want that when you're trying to get a decent sound going. ### 3. Power On and Pair the Primary Speaker Turn on the first JBL speaker you want to use. This will be your "primary" speaker. Pair it with your smartphone, tablet, or whatever Bluetooth device you're using. You'll usually go into your device's Bluetooth settings, find the JBL speaker in the list, and connect. You should hear a confirmation sound from the speaker. ### 4. Activate the Linking Feature on the Primary Speaker Now, press the dedicated Connect, Connect+, or PartyBoost button on your primary speaker. It usually lights up or flashes to indicate it's looking for other speakers. ### 5. Activate the Linking Feature on Secondary Speakers Turn on your second (and any subsequent) compatible JBL speakers. Then, press *their* Connect, Connect+, or PartyBoost button. Make sure you press the *correct* button for the tech they support. They should then connect to the primary speaker. You'll often hear a little chime or see the button's light change to a solid colour once they're linked. ### 6. Adjust Sound and Placement Once they're all linked up, you can usually use the JBL Connect app to switch between "Party Mode" (all speakers play mono) or "Stereo Mode" (left/right channels split between two speakers). Experiment with placement. For stereo, try placing them a few metres apart. For Party Mode, spread them out to fill a larger area with sound. Don't just chuck them all in a corner, eh? That'll sound like rubbish. ## Using the JBL Portable App This app, sometimes still called "JBL Connect" for older models, is your best friend when managing multiple JBL speakers, particularly Connect+ and PartyBoost ones. You can download it for free on iOS and Android. With the app, you can: * **Check compatibility:** Often, the app will tell you which speakers can connect. * **Update firmware:** Crucial for stability and new features. Always keep your firmware up to date. * **Switch modes:** Easily toggle between Party Mode (mono, all speakers) and Stereo Mode (left/right, two speakers). * **Rename speakers:** Handy if you have several of the same model. * **Adjust settings:** Some models allow EQ adjustments or light show controls. I always recommend people get the app. It just makes life easier, especially if you're regularly linking speakers. It's a bit clunky sometimes, like most companion apps, but it does the job. ## Troubleshooting Common Issues Linking speakers isn't always sunshine and rainbows. Here are a few common snags I've come across and how to fix 'em. * **Speakers won't connect:** * **Check compatibility first!** This is 90% of the problem. Are they all Connect, Connect+, or PartyBoost? If not, they won't link. Simple as. * **Are they charged?** As I said before, low battery can mess things up. * **Are they too far apart?** Bluetooth has a range, usually about 10-15 metres without obstacles. * **Too many devices nearby?** Wi-Fi routers, other Bluetooth gadgets, even microwaves can interfere. Try moving your speakers away from other electronics. * **Restart everything:** Your phone, the primary speaker, the secondary speakers. A good old "turn it off and on again" often works wonders. * **Reset speakers:** Some JBL speakers have a reset function (often holding volume + and play/pause for a few seconds). Check your manual for the exact method. This can clear any stubborn connection issues. * **Sound drops out or stutters:** * **Distance:** Are the speakers too far from each other or the primary Bluetooth source? * **Obstacles:** Walls, furniture, even people can block Bluetooth signals. Try to get a clear line of sight. * **Interference:** Again, other wireless devices can cause issues. * **Firmware:** Ensure all speakers have the latest firmware via the JBL Portable app. * **Only one speaker playing in PartyBoost/Connect+:** * **Did you press the button on *all* speakers?** Sometimes you just forget one. Easy mistake. * **Check the app:** The JBL Portable app will show you which speakers are connected and in what mode. You might need to manually switch to Party or Stereo mode if it's stuck on single speaker playback. ## Brands That Work Well With JBL (and Those That Don't) Alright, let's be clear here: JBL's multi-speaker tech is proprietary. That means you *can't* link a JBL speaker with a Sony, Bose, Ultimate Ears, or any other brand's speaker using their Connect/Connect+/PartyBoost system. It just doesn't work that way. Each brand has its own ecosystem. If you want to link different brands, you're generally looking at some more involved setups, usually involving a Bluetooth transmitter and multiple receivers, or a more traditional wired multi-room audio system. For portable Bluetooth, stick to the same brand and compatible tech. I've seen some folks try to use a 3.5mm AUX cable to daisy-chain speakers from different brands, but honestly, it's a faff, introduces latency, and you often get a load of hum and noise. Not worth the bother for portable speakers, in my humble opinion. ## Comparison Table: JBL Connect Tech | Feature | JBL Connect | JBL Connect+ | JBL PartyBoost | | :------------------ | :------------------------------------------ | :----------------------------------------- | :----------------------------------------- | | **Introduced** | Earlier models (e.g., Flip 3, Charge 3) | Mid-range models (e.g., Flip 4, Charge 4) | Latest models (e.g., Flip 5/6, Charge 5) | | **Max Speakers** | Up to 2 (stereo) or several (mono) | Up to 100 | Up to 100 | | **Stereo Pairing** | Yes (2 speakers) | Yes (2 speakers) | Yes (2 speakers) | | **App Support** | Limited/None (depends on model) | Yes (JBL Connect/Portable App) | Yes (JBL Portable App) | | **Compatibility** | Only with other JBL Connect speakers | Only with other JBL Connect+ speakers | Only with other JBL PartyBoost speakers | | **Example Models** | Flip 3, Charge 3, Pulse 2, Xtreme 1 | Flip 4, Charge 4, Pulse 3, Xtreme 2, Boombox 1 | Flip 5/6, Charge 5, Pulse 4/5, Xtreme 3, Boombox 2/3 | | **Key Difference** | Original version, basic multi-speaker | Enhanced range and number of speakers | Newest protocol, improved stability/sound | ## Tips for Optimising Your Multi-Speaker Setup Getting a load of speakers to work together isn't just about pressing buttons; it's about making them sound good. Here are a few tricks I've learned over the years. * **Placement is King:** Don't just plonk them down anywhere. For stereo, try an equilateral triangle setup with you at the apex. For party mode, spread them out evenly around the room or garden. Avoid corners if you can, as they can make the bass boomy and indistinct. * **Volume Matching:** If you're mixing speaker sizes (say, a Flip with an Xtreme), they'll have different volume outputs. The app can sometimes help, but you might need to adjust individual speaker volumes if the option is there, or just accept that the bigger speaker will dominate. Generally, it's best to use identical models for the most balanced sound. * **Environment Matters:** Hard surfaces (tiles, glass) will reflect sound and make it sound echoey. Soft furnishings (curtains, sofas, carpets) will absorb sound and make it sound dead. A balance is always best. Outdoors, you've got no reflections, so you need more power to fill the space. * **Keep them Charged:** I'm repeating myself, I know, but it's genuinely important. A dying speaker will be the first to drop out of a linked group. * **Firmware Updates:** Seriously, don't skip these. JBL often pushes out fixes and performance improvements through firmware. It can solve compatibility issues you didn't even know you had. ## JBL Connect+ vs. PartyBoost: Is it Worth Upgrading? This is a question I get asked a lot. "Robert, I've got a Charge 4, should I get a Charge 5?" And honestly, it's a nuanced answer. If you've already got a collection of Connect+ speakers (like a Charge 4 and a Flip 4), then buying a new PartyBoost speaker (like a Charge 5) means it *won't* link with your existing setup. You'll end up with two separate ecosystems, which is a bit of a waste. However, if you're just starting out, or you only have one older speaker and you're looking to buy more, then going for the latest PartyBoost models makes sense. The tech is generally more refined, and you'll be future-proofing yourself a bit more. The sound quality improvements between generations are usually incremental rather than revolutionary for these portable speakers, but they are there. My advice? If you're heavily invested in Connect+, stick with it if you want multi-speaker functionality. Grab another Connect+ speaker if you can find one at a decent price. If you're buying your first speaker, or replacing an old, solitary one, then absolutely go for a PartyBoost model. Don't throw good money after bad trying to link incompatible kit. ## FAQ Section ### Can I connect a JBL Flip 4 with a JBL Flip 5? No, unfortunately not. The Flip 4 uses JBL Connect+, while the Flip 5 uses the newer JBL PartyBoost technology. They are not cross-compatible, so they can't be linked together. ### How many JBL speakers can I connect together? With JBL Connect+, you can link up to 100 speakers. With JBL PartyBoost, you can also link up to 100 PartyBoost-enabled speakers. However, for true stereo sound, you can only pair two compatible speakers. ### Why won't my JBL speakers connect to each other? The most common reason is incompatibility. Ensure all speakers you're trying to link use the *same* JBL multi-speaker technology (Connect, Connect+, or PartyBoost). Other reasons could be low battery, interference, speakers being out of range, or needing a firmware update. ### Do I need the JBL Portable app to connect my speakers? No, you can usually link them by just pressing the physical buttons on the speakers. However, the JBL Portable app (or JBL Connect app for older models) makes managing connections, updating firmware, and switching between Party and Stereo modes much easier. I always recommend using it. ### Can I connect a JBL speaker to a non-JBL speaker? No, JBL's multi-speaker linking technologies (Connect, Connect+, PartyBoost) are proprietary. They only work with other compatible JBL speakers. You cannot link them with speakers from other brands like Sony, Bose, or Ultimate Ears for multi-speaker playback. ## Final Word So, there you have it. Connecting your JBL speakers isn't rocket science, but it does require a bit of awareness about which "flavour" of JBL tech your specific models are using. Get that bit right, and you're golden. Get it wrong, and you'll be scratching your head, wondering why your shiny new Charge 5 won't chat to your trusty old Flip 4. It's just the way these things go with proprietary wireless systems. My main takeaway? Always check compatibility *before* you buy. If you've got a set of Connect+ speakers, stick to Connect+ if you're expanding. If you're starting fresh, jump straight to PartyBoost. And honestly, for a garden party or workshop background music, two properly paired JBLs using PartyBoost sound cracking. You really don't need 100 of them, trust me. Enjoy the tunes, eh?
