Let’s be real: we all love when our Bluetooth headphones just connect, no drama. But then, out of nowhere—error code 004 shows up, and suddenly the music stops.
Usually, you can fix Bluetooth headphones error code 004 by removing the headphones from your device’s Bluetooth list, restarting both your device and the headphones, and pairing them again. Sometimes, all your gear needs is a quick break and a fresh start.
We get it—it’s tempting to call your headphones cursed or just toss them. But hang on.
There’s actually a method to this Bluetooth madness, and a few easy steps might save you some frustration. Let’s figure out error 004 and get the music flowing again.
Understanding Bluetooth Error Code 004
When Bluetooth headphones suddenly flash a “Code 004” error, your device is basically saying, “I have no idea what’s happening.” These glitches can turn a simple jam session into a troubleshooting headache.
You might wonder, what even caused this?
What Triggers Error Code 004
Error Code 004 is like an unwanted guest at a party. It usually pops up when several things go wrong at once.
The most common cause? Bluetooth driver issues. Maybe your driver’s outdated, corrupted, or just tired.
Sometimes, your headphones and computer don’t speak the same Bluetooth “language.” Maybe you’ve got shiny new headphones but an ancient laptop, or your device just refuses to play nice with new friends.
Other times, interference from stuff like Wi-Fi routers—or your neighbor’s weird gadgets—can mess with the connection.
Pairing issues love causing this error, too. If you’ve paired your headphones with too many devices or the pairing process gets interrupted, error code 004 might appear.
Here’s a quick look at what can trigger it:
| Trigger | Explanation |
|---|---|
| Outdated driver | Needs update or reinstall |
| Device compatibility | Old Bluetooth version or hardware mismatch |
| Wireless interference | Competing signals in the area |
| Pairing problem | Too many paired devices or interrupted setup |
Common Symptoms and Annoyances
When error 004 shows up, you’ll usually notice a bunch of annoying stuff. The headphones might refuse to connect no matter how many times you restart or try to sweet-talk them.
Sometimes, your device flashes a driver error message, or the Bluetooth settings just vanish. Audio might stutter, cut out, or not play at all.
Other times, your device lists the headphones, but nothing happens when you try to connect. Maybe your headphones worked fine yesterday, but today they act like strangers.
Re-pairing might fail, or your computer asks for a missing driver and then refuses to install it. If this sounds familiar, welcome to the Code 004 club.

Quick Fixes for Bluetooth Headphones Error Code 004
Error code 004 is super annoying, but you can usually fix it with a few simple steps. With some patience and maybe a laugh, you’ll be back to your music soon.
Restarting Bluetooth Without Panicking
First, don’t freak out when you see the error. Restarting Bluetooth often does the trick and doesn’t require any tech wizardry.
Here’s what we usually do:
- Turn Bluetooth off and on. Find the Bluetooth icon and toggle it off. Wait about 10 seconds. Then switch it back on.
- Forget and re-pair. If that doesn’t work, “forget” your headphones in Bluetooth settings. It’s like erasing an awkward memory.
- Restart your device. The classic “turn it off and on again.” Sometimes, devices just need a break.
If you want more help, Microsoft’s got some Bluetooth troubleshooting tips.
Charging Headphones for Optimal Performance
Let’s be honest, everything works better with a full battery. Headphones are no different—they act up when they’re running low.
Quick charging tips:
- Plug in your headphones and let them charge for at least 30 minutes.
- Check the charging cable and port for dust—seriously, clean them out.
- Use the original charger if you still have it.
A fully charged battery can make all the difference. Most devices have a little light to show charging status; if there’s no light, it’s time to check the charger.
Switching Pairing Mode Like a Pro
If nothing else works, try putting your headphones into pairing mode. Most Bluetooth headphones have a special pairing mode that resets their memory.
Here’s how we usually do it (but check your manual to be sure):
- Turn off the headphones.
- Hold down the power or pairing button for 5-15 seconds. You’ll probably see a flashing light—think of it as disco mode.
- Delete the headphones from your device’s Bluetooth list, then search and connect again.

And hey, manuals are your friend if your headphones use a weird button combo.
Deep Dive: Troubleshooting Error Code 004 on Windows
Error Code 004 on Windows can really test your patience. You’ll need to check drivers, use some hidden tools, and maybe even resort to the classic off-and-on routine.
Updating Bluetooth Drivers Reluctantly
Honestly, updating drivers isn’t fun, but sometimes it’s the only way. Open Device Manager by right-clicking the Start button and picking Device Manager.
Find Bluetooth, right-click your adapter, and choose Update driver. If that doesn’t help, uninstall and reinstall the driver.
Sometimes Windows 10 or 11 will grab the right file on its own. If you’re feeling adventurous, you can roll back the driver—just right-click, go to Properties, then Driver, and look for Roll Back Driver.
It’s not glamorous, but how-to guides say driver issues cause most Bluetooth headaches. After you update or reinstall and reboot, there’s a good chance Error Code 004 will disappear.
Using the Bluetooth Troubleshooter (It Exists!)
Windows actually has a Bluetooth troubleshooter, though they kind of hide it. Type “troubleshoot” in the search bar.
Click Troubleshoot settings, then Other troubleshooters (Windows 11) or Additional troubleshooters (Windows 10). Click Run next to Bluetooth and let it do its thing.
The troubleshooter checks for things like broken drivers or services not running. Sometimes it even fixes stuff for you.
Microsoft has more details on their Bluetooth troubleshooter. It’s not perfect, but it can save you a ton of time.
Resetting Network Settings—Turn It Off and On Again
If nothing else works, try resetting your network settings. It’s not just for Wi-Fi problems—it can help with stubborn Bluetooth errors, too.
Go to Settings, then Network & Internet, and look for Network reset at the bottom of the Status page (Windows 10) or in Advanced network settings (Windows 11).
When you reset, Windows forgets all your network connections. You’ll need to reconnect to Wi-Fi and pair Bluetooth devices again.
It’s a pain, but sometimes starting fresh is the only way to fix things. Just don’t forget your Wi-Fi passwords!
Taming Devices: Preventing Multiple Connections Mishaps
Let’s be honest—sometimes our Bluetooth headphones seem busier than we are. With so many devices trying to connect, it’s easy to run into errors like code 004.
Managing Bluetooth Settings Across Devices
Headphones often get paired with everything from phones to laptops, and that can cause chaos. If you don’t keep track, devices start fighting for the connection.
It helps to check and update the paired device list on your headphones. Most models only remember a few devices at a time.
If you hit the limit, new devices might not pair or old ones might drop off. Here’s what we usually do:
- Forget the headphone connection on devices you no longer use.
- Rename your headphones so you can spot them easily in lists.
- Only keep necessary devices paired.
Keeping things tidy reduces the chances of interference and connection errors.
Stable Connections: One at a Time, Please
Bluetooth headphones really don’t like multitasking. Most of them will only play audio from one device at a time, even though they remember a bunch of devices.
If you try to connect more than one device at once, your headphones might get confused and start flashing weird error codes. To keep things smooth, it helps to disconnect from any device you’re not using before you switch to a new one.
Some headphones offer a quick-switch button combo, but honestly, just disconnecting manually in your settings usually works fine.
Listening from only one device at a time usually gives you a much more stable experience. If you notice audio dropping or weird connection hiccups, check that you’ve only got one device active. That trick solves most issues.
For the official word on how many devices your headphones can pair with or connect to, Sennheiser lays out clear guidelines in their manuals.
Advanced Solutions for Persistent Error Code 004
Sometimes Error Code 004 just doesn’t want to leave, no matter what you try. At that point, you might need to channel your inner tech detective and dig a little deeper to get your Bluetooth headphones working again.
Checking Bluetooth Service Like a Detective
Alright, let’s put on our detective hats for a second. The Bluetooth service has to run properly, or nothing else will work.
If the Bluetooth service on your device has stopped, your headphones can’t connect—no music, no podcasts, just silence.
Here’s a quick Bluetooth mystery-solving routine:
- Open Device Manager.
- Find the “Bluetooth” section.
- Right-click your Bluetooth adapter and hit Properties.
- Under “General,” check if it says “This device is working properly.”
If it doesn’t, try this:
-
Restart the Bluetooth service:
- Press
Win + R, typeservices.msc, and press Enter. - Scroll to “Bluetooth Support Service.”
- Right-click and choose Restart.
- Press
-
Reinstall the driver:
- Uninstall your Bluetooth adapter in Device Manager, then reinstall it.
If things go well, your headphones might finally listen to you again. If you get stuck, the steps at Microsoft Community can help.
Dealing With Software Glitches Gracefully
Software glitches have a knack for showing up at the worst times. Maybe it’s after an update, or maybe your device just feels stubborn that day. Either way, you can usually fight back with a bit of logic and patience.
Here’s a glitch-busting checklist:
-
Update everything:
Make sure your headphones’ firmware and your operating system are both updated. -
Remove and re-pair:
Go into Bluetooth settings, remove your headphones, then pair them again. Sometimes that’s all it takes to clear up old, confused connections. -
Reboot:
Yep, just restart your device. It’s a cliché, but it works more often than you’d think.
If Error 004 still hangs around after all that, you might want to retry the entire Bluetooth setup process. Or, pair your headphones with a different device to see if the headphones themselves are the problem.
It’s honestly pretty normal for software to get confused now and then—happens to the best of us, and apparently, to our gadgets too.
Bonus Round: Other Bluetooth Devices and Compatibility
Sometimes, it’s not just your headphones acting up. Keyboards, speakers, and other gadgets have their own Bluetooth quirks.
Your troubleshooting skills can help with all kinds of Bluetooth gear, not just the stuff you wear on your head.
Bluetooth Keyboards and Speakers: Are They to Blame?
Let’s be real—pairing a Bluetooth keyboard sometimes feels like trying to teach a cat to fetch. It’s possible, but honestly, it’s unpredictable and a little bit maddening.
These devices can mess with other connections or just hog the entire Bluetooth channel. When our speaker and headphones decide to fight for control, everything grinds to a halt until we yank one off and try pairing again.
We should double-check compatibility every time. Not every speaker or keyboard will play nice with every computer or phone.
Windows loves asking for PIN codes with some of these gadgets, and honestly, I’ve never typed “0000” so many times in my life. If nothing’s working, maybe it’s time to reboot the device—or just go old-school and remove it in the Bluetooth settings before pairing again.
Usually, that fixes things. Well, at least until the Bluetooth mouse starts acting up out of nowhere.
From a young age, I have always had a big interest in technology, and this blog is an extension of that interest. Through this blog, I hope to provide others with all of the information they need regarding tech options to consider, and things such as compatibility. Some of the different items I will be discussing include headphones, smartwatches, and how to fix common issues.
