Quick Answer:
- Start with Windows Update. Go to Settings > Windows Update > Advanced options > Optional updates and install anything listed under wireless or Bluetooth.
- Then check Device Manager — press Windows + X, expand Bluetooth, right-click the entry naming a chipset, and choose Update driver.
- For the newest version, download from your laptop or motherboard brand, not from a generic driver site.
- After updating, re-pair your headphones and turn off the adapter’s power saving setting. Both get reset by updates.
Most guides treat a Bluetooth driver update as a repair job — something you only do when things are broken. On a PC you listen to music on, it’s more than that. Your Bluetooth driver is what negotiates with your headphones over which audio codec to use. It decides whether good headphones get AAC or quietly fall back to plain SBC, and whether Windows can even see that your headset supports LE Audio. There’s a full explanation of that further down, but the update itself takes five minutes, so let’s do that first.
Method 1: Windows Update
Start here. It’s the safest source, it’s two clicks, and Bluetooth fixes often arrive bundled inside a wireless package rather than listed as a Bluetooth update.
- Press Windows key + I to open Settings.
- Go to Windows Update, then Advanced options.
- Click Optional updates.
- Expand Driver updates. Look for anything naming Bluetooth or your wireless adapter.
- Tick it, click Download and install, then restart.
Windows 10: the path is Settings > Update & Security > Windows Update > View optional updates. Nothing listed? That usually means Microsoft has nothing newer certified for your adapter, not that you’re up to date. Carry on to Method 2.
Method 2: Device Manager
This checks the same catalog but targets your specific adapter, so it sometimes finds something the Optional updates page didn’t surface.
First, Find the Right Entry
Device Manager lists several things under Bluetooth and only one of them is the adapter.
- Press Windows key + X and click Device Manager.
- Expand Bluetooth.
- Find the entry naming a chipset — Intel Wireless Bluetooth, Realtek Bluetooth Adapter, Qualcomm Atheros Bluetooth, MediaTek Bluetooth Adapter, or Broadcom Bluetooth. That’s the one.
Everything else is noise. Entries like Microsoft Bluetooth Enumerator and Bluetooth Device (RFCOMM Protocol TDI) are software layers, and your paired headphones show up in that list too. Leave them alone.
Then Update It
- Right-click your adapter and select Properties, then open the Driver tab. Write down the Driver Version, Driver Date, and Driver Provider — you’ll want these to confirm the update worked.
- Close that window, right-click the adapter again, and select Update driver.
- Choose Search automatically for drivers.
- Restart when prompted.
Your headphones will disconnect during the install and should reconnect after the restart. If they don’t, that’s normal — it’s covered in the checklist below. If the Driver Provider says Microsoft, you’re on a generic driver. That’s the strongest single reason to go and get the manufacturer’s package instead, and Method 3 explains why it matters for sound quality.
Method 3: Your Laptop or Motherboard Brand
This is the one that actually changes what your headphones sound like, because OEM packages expose capabilities the generic driver doesn’t.
- Find your exact model. On a laptop it’s on the underside sticker. On a desktop, press Windows key + R, type
msinfo32, and read System Model and BaseBoard Product. - Go to your brand’s support and downloads page — Dell, HP, Lenovo, ASUS, Acer, MSI, Gigabyte, ASRock.
- Enter the model and select your Windows version.
- Look under Bluetooth, Wireless, or Network. On many models it’s inside a combined wireless package.
- Compare the version and date against what you noted in Method 2. Only install if theirs is genuinely newer.
- Run the installer and restart.
Most brands also offer a first-party updater that only touches drivers validated for your model: Lenovo Vantage, MyASUS, Dell SupportAssist, HP Support Assistant, MSI Center. Those are safe. Generic driver-updater programs are not. Bluetooth is one of the most aggressively targeted search terms on fake download portals, precisely because people look for it in a hurry when nothing is pairing. Stick to your brand’s own domain.
Method 4: Straight from the Chipset Maker
Use this when your brand hasn’t published anything in a year or more, which is common on older laptops.
- Intel — download the Intel Wireless Bluetooth driver from intel.com, or let the Intel Driver and Support Assistant find it. Intel is the most generous vendor here and usually has something newer than your laptop brand.
- Realtek, MediaTek, Qualcomm, Broadcom — these are generally distributed only through PC manufacturers. If your brand has nothing, you’ve likely reached the end of the road for that adapter.
If your adapter is genuinely abandoned and you care about audio quality, a USB Bluetooth transmitter is worth considering. Codec negotiation happens inside the dongle rather than in Windows, so a good one can give you codecs your PC’s built-in radio never will. Windows treats it like an external sound card.
Method 5: Install a Driver Manually
When the download is a folder of files with no installer inside.
- Right-click the .zip and choose Extract All. Unpack it somewhere you’ll remember.
- Open Device Manager, right-click your Bluetooth adapter, select Update driver.
- Choose Browse my computer for drivers.
- Point it at the extracted folder, tick Include subfolders, click Next.
- Restart when prompted.
If Windows refuses the driver with a signature warning, don’t try to force it. Go back and get a properly signed package from the manufacturer — disabling signature enforcement on a machine you actually use isn’t worth it.
The Five-Minute Check After You Update
Driver updates reset things. Work through this list or you’ll spend the next week blaming the new driver for something it just switched off.
- Confirm the version changed. Device Manager, Properties, Driver tab. Same version and date as before means the install silently failed.
- Turn power saving back off. Right-click the adapter, Properties, Power Management tab, untick Allow the computer to turn off this device to save power. Updates re-enable this every time, and it’s behind most “my mouse lags after idle” complaints.
- Re-check the LE Audio toggle. Settings, Bluetooth & devices, Devices. If it appeared for the first time, turn it on — the next section explains why that matters.
- Re-pair anything that didn’t reconnect. Remove the device fully in Settings, restart the headphones, pair again from scratch.
- Check your output device. Click the speaker icon in the taskbar. Updates often switch the default output somewhere else.
- Test the mic separately from playback. They use different profiles and one can work while the other doesn’t. Our free mic test tool checks it in the browser in a few seconds.
- Listen to something you know well. A track you’ve heard a hundred times tells you more about whether the codec changed than any spec sheet.
Why Your Driver Decides How Your Headphones Sound
This is the part nobody explains, and it’s the reason this article exists on an audio site rather than a Windows one. When your headphones connect for music playback, Windows uses a profile called A2DP and picks a codec that both sides support. The codec is the compression format the audio travels in, and the difference between the best and worst option is audible on decent headphones. Here’s what Windows actually supports for standard Bluetooth audio:
- SBC — the universal fallback. Every device supports it. It’s also the worst-sounding option.
- AAC — better, and what most Apple and many mainstream earbuds prefer.
- aptX Classic — supported from Windows 11 version 21H2 onward.
- aptX Adaptive — documented from Windows 11 24H2, but only on systems with a compatible Qualcomm Bluetooth radio.
- LC3 — the LE Audio codec, available on 24H2 and later when your radio, driver, and headset all support it.
What Windows does not support: LDAC and aptX HD are not in Microsoft’s standard codec set. If you bought Sony headphones specifically for LDAC, they will not use it on a stock Windows PC no matter how many drivers you install. That’s a platform limitation, not a fault you can update your way out of. Where the driver comes in. Codec availability isn’t decided by your headphones alone. Your Bluetooth radio has to support the codec, and your driver has to expose it to Windows.
A generic Microsoft driver frequently exposes less than the manufacturer’s own package does — which is exactly how a pair of aptX headphones ends up quietly streaming SBC on a PC that could have done better. If your headphones sound noticeably worse on your PC than on your phone, and everything else is equal, a stale or generic Bluetooth driver is one of the first things to rule out.
Check Whether You Have LE Audio
LE Audio is the meaningful upgrade here. It uses the LC3 codec, and on compatible hardware it lets Windows keep stereo playback running while your microphone is active — which solves the mono-on-calls problem that has annoyed PC listeners for years. To check: go to Settings > Bluetooth & devices > Devices and look for Use LE Audio when available.
If the toggle isn’t there, your PC or its drivers haven’t exposed LE Audio. Updating the Bluetooth driver is the single most likely thing to make it appear, assuming the hardware supports it. You’ll also need Windows 11 24H2 or later — check with Windows key + R, then type winver. Worth being realistic: LE Audio support on Windows is still patchy, and the toggle showing up doesn’t guarantee your headset is actually using it. Both ends have to negotiate it successfully.
Does This Work on Windows 10?
The update methods do. Windows Update, Device Manager, manufacturer downloads, and manual .INF installs all behave the same way — the only difference is the Windows Update path, which is Settings > Update & Security > Windows Update > View optional updates. The audio side is where Windows 10 falls short. LE Audio, the LC3 codec, and aptX Adaptive are all Windows 11 features, and the LE Audio toggle doesn’t exist on Windows 10 at all. You’re limited to SBC and AAC in practice, and no driver update changes that.
Worth knowing: Windows 10 reached end of support on 14 October 2025. The Consumer Extended Security Updates programme runs to 12 October 2027, but it delivers security patches only — it’s not a driver channel, and manufacturers are steadily dropping Windows 10 from their download pages. If your PC can run Windows 11 and you care about Bluetooth audio quality, upgrading does more for your headphones than any driver will.
When a Driver Update Is Not the Answer
Plenty of things that look like driver problems aren’t. Find your symptom here before you go any further.
| What’s happening | Is it the driver? | Where to look |
|---|---|---|
| Music sounds flat or worse than on your phone | Often yes | The codec section above |
| Audio drops to mono the moment you join a call | Partly | Below |
| Headphones pair but produce no sound at all | Rarely | Below |
| Bluetooth toggle missing from Settings entirely | No | Next section |
| Audio stutters or cuts out during playback | Sometimes | Our stuttering guide |
| Headphones won’t leave pairing mode | No | Our pairing mode guide |
| Mouse or keyboard lags after sitting idle | No | Power saving, step 2 above |
Your Audio Collapses to Mono on Calls
This isn’t a bug and no driver fixes it on standard Bluetooth. Classic Bluetooth forces a choice: A2DP gives you high-quality one-way stereo, Hands-Free gives you two-way voice at telephone quality. Open a mic and Windows switches profiles, and your music turns to mush.
Your options are to use LE Audio if both your PC and headset support it, use your headphones’ own USB dongle if they came with one, or simply use a separate microphone so the headset never has to enter call mode. If your headset shows up twice in your output list — once as Stereo and once as Hands-Free — pick Stereo for music and only switch when you actually need the mic.
Paired, Connected, No Sound
Almost always the output device, not the driver. Click the speaker icon in the taskbar and pick your headphones from the list. Also check Volume mixer for an app-level mute — browsers are the usual culprit.
Audio Stutters and Cuts Out
A driver update helps sometimes, but the usual cause is radio interference. Bluetooth shares the 2.4GHz band with Wi-Fi, and USB 3.0 ports and hubs are notorious sources of noise in that band. We’ve covered the full diagnostic process in our guide to fixing Bluetooth audio stuttering on Windows 11.
The Problem Is the Headphones, Not the PC
If your headphones misbehave on every device, the driver was never the issue. Check for a firmware update in the manufacturer’s companion app — and if one goes wrong mid-install, our guide on a firmware update that failed halfway covers the recovery. For headphones that won’t exit pairing mode, or that switch themselves on unprompted, the fix is on the headphone side too.
Bluetooth Missing from Settings Entirely?
No Bluetooth toggle in Settings and nothing under Bluetooth in Device Manager means Windows can’t see the hardware. There’s no driver to update. Work through these in order.
- Airplane mode. It kills Bluetooth along with Wi-Fi and it’s easy to hit by accident with a function key.
- Hardware switch. Some laptops have a physical wireless switch, or an Fn key combination — often F2, F5, or F12.
- Show hidden devices. In Device Manager, click View > Show hidden devices, then check under Bluetooth and Other devices again.
- Bluetooth Support Service. Press Windows key + R, type
services.msc, find Bluetooth Support Service, right-click it, open Properties, set Startup type to Automatic, and click Start. - Run the troubleshooter. Settings > System > Troubleshoot > Other troubleshooters, then run Bluetooth.
- Check BIOS. Restart into BIOS or UEFI setup and look for a wireless or Bluetooth option under Advanced or Onboard Devices. It can be switched off there.
If the adapter still doesn’t appear, the driver needs a full reinstall rather than an update — uninstall the device in Device Manager with the remove-driver box ticked, restart, and let Windows rebuild it before installing your manufacturer’s package. One thing worth knowing: on almost every laptop, Bluetooth and Wi-Fi share the same physical module. If both have failed at once, suspect the hardware rather than two unrelated drivers.
Error Codes, Quickly
Right-click the adapter, open Properties, and read Device status on the General tab.
| Code | Meaning | What to do |
|---|---|---|
| Code 10 | Device cannot start | Driver mismatch. Uninstall, restart, install the OEM package |
| Code 28 | No driver installed | Get the OEM wireless package from your brand |
| Code 31 | Driver won’t load | Corrupted package. Clean uninstall, then reinstall |
| Code 43 | Device reported a fault | Reinstall. If Wi-Fi is also failing, suspect the module |
| Code 45 | Device not connected | Often a USB dongle that’s been unplugged |
Frequently Asked Questions
Will updating my Bluetooth driver improve sound quality?
It can. Your driver determines which audio codecs Windows can offer your headphones, and a generic Microsoft driver often exposes fewer than the manufacturer’s own package. If your headphones sound worse on your PC than on your phone, installing the OEM Bluetooth driver is one of the first things to try. It will not exceed what your hardware supports, though.
Which Bluetooth codecs does Windows 11 actually support?
For standard Bluetooth audio, Windows supports SBC, AAC, aptX Classic from version 21H2, and aptX Adaptive from 24H2 on systems with a compatible Qualcomm radio. LC3 is available through LE Audio on 24H2 and later. LDAC and aptX HD are not part of Microsoft’s standard codec set, so Sony headphones bought for LDAC will not use it on a stock Windows PC.
Why do my headphones sound worse on my PC than on my phone?
Usually because your phone negotiated a better codec. Phones commonly support AAC or LDAC, while a Windows PC with a generic driver may fall back to SBC. Install your manufacturer Bluetooth driver, check whether LE Audio is available, and if your adapter is old, consider a USB Bluetooth transmitter that handles codec negotiation itself.
How do I know if my PC supports LE Audio?
Go to Settings, then Bluetooth and devices, then Devices, and look for a toggle called Use LE Audio when available. You need Windows 11 version 24H2 or later, which you can check by running winver. If the toggle is missing, your drivers have not exposed LE Audio, and updating the Bluetooth driver is the most likely way to make it appear.
Why does my music drop to mono when I join a call?
Classic Bluetooth forces a choice between high-quality one-way stereo and two-way voice at telephone quality. Opening a microphone switches the profile and degrades playback. No driver update fixes this. LE Audio solves it on compatible hardware, and using a separate microphone avoids it entirely.
Which Bluetooth entry in Device Manager should I update?
The one naming a chipset, such as Intel Wireless Bluetooth or Realtek Bluetooth Adapter. Entries like Microsoft Bluetooth Enumerator and Bluetooth Device RFCOMM Protocol TDI are software layers, and your paired headphones appear in that list as connected devices. Only the chipset entry is the adapter driver.
Do Bluetooth driver updates work the same on Windows 10?
The update methods are identical, apart from the Windows Update path, which is Settings then Update and Security then Windows Update then View optional updates. The audio features differ, though. LE Audio, LC3, and aptX Adaptive are Windows 11 only, so Windows 10 is limited to SBC and AAC in practice regardless of which driver you install.
Why do my headphones stop reconnecting after a driver update?
Bluetooth driver updates commonly clear stored pairing records. Remove the device completely in Settings, restart the headphones, and pair again from scratch. It is normal and takes less time than troubleshooting it.
Should I use a USB Bluetooth dongle instead?
It is worth it if your built-in adapter is old or abandoned by its manufacturer, or if you want a codec Windows does not support natively. A good transmitter handles codec negotiation inside the dongle, so Windows treats it like an external sound card and your headphones get a better connection than the PC radio could provide.
