How do I play music through Bluetooth on my PC?

What is Bluetooth?

Bluetooth is a short-range wireless technology that allows devices to wirelessly connect and communicate over short distances. The name “Bluetooth” refers to Danish King Harald Bluetooth, who united Denmark and Norway in the 10th century, just like how Bluetooth wireless technology allows different devices to communicate. The technology was developed in 1994 by Dr. Jaap Haartsen while working at Ericsson (The History of Bluetooth – Auris).

Bluetooth uses radio waves operating in the 2.4 – 2.485 GHz range to wirelessly transmit data between devices like smartphones, speakers, headphones, computers, printers, and more. Instead of using cables to connect devices, Bluetooth allows data transfer through these radio waves once two devices are paired. The wireless signals are encoded using frequency-hopping spread spectrum (FHSS), which allows Bluetooth connections to avoid interference with other wireless signals operating in the same frequency band.

There have been several versions of Bluetooth released over the years with improvements in speed, range, and features. Some key Bluetooth versions include Bluetooth 1.0 and 1.0B, Bluetooth 2.0 + EDR, Bluetooth 3.0, Bluetooth 4.0, Bluetooth 4.1, Bluetooth 4.2, Bluetooth 5.0, and the latest Bluetooth 5.2. Newer versions of Bluetooth offer faster data transfer speeds and longer ranges between devices. Compatibility depends on the Bluetooth version – devices with different Bluetooth versions may not be able to connect or operate optimally.

Check Bluetooth compatibility

To play audio through Bluetooth on your PC, the first step is to make sure your computer is Bluetooth compatible. There are two things to check:

  • Determine if your PC has built-in Bluetooth or needs an adapter. Many newer Windows laptops and desktops have Bluetooth built into the motherboard. If your PC does not have Bluetooth, you will need to purchase a USB Bluetooth adapter.
  • Check that your PC meets Bluetooth requirements for the version you need. Most Bluetooth speakers and headphones require Bluetooth 4.0 or higher. To check your Bluetooth version on Windows 10, go to Settings > Devices > Bluetooth and other devices. Look at the ‘Bluetooth’ section to see the version.

According to the MacOS Sonoma and Hearing Aids (MFi) forum, Bluetooth hardware requirements vary across operating systems and devices. So it’s important to verify Bluetooth compatibility before trying to connect your Bluetooth speaker or headphones to avoid issues.

Enable Bluetooth on your PC

To enable Bluetooth on a Windows 10 PC, first locate the Bluetooth settings. You can access Bluetooth settings by going to Start > Settings > Devices > Bluetooth & other devices. Make sure the toggle switch next to Bluetooth is turned on. If you don’t see a Bluetooth option in Settings, your PC may not have built-in Bluetooth capability. You may need to use a USB Bluetooth adapter instead.

Once Bluetooth is enabled, make sure visibility is turned on so other devices can find your PC when pairing. Under Bluetooth settings, click the toggle next to “Make this device discoverable to Bluetooth devices”. This allows your PC to be visible to compatible Bluetooth devices for pairing. The setting will turn off after 2 minutes, but you can turn it back on when you need to connect a new device.

Pair your Bluetooth speaker or headphones

To pair a Bluetooth speaker or headphones to your PC, you first need to put the device into pairing mode. The instructions for this vary by device, but often involve pressing and holding a “pair” or “connect” button until an indicator light flashes. Refer to your device’s documentation if you’re unsure how to activate pairing mode.

Once your Bluetooth device is in pairing mode, go to Settings > Devices on your Windows PC and select “Add Bluetooth or other device.” Your PC will search for nearby Bluetooth devices in pairing mode and display them under “Add a device.” Select your Bluetooth speaker or headphones from the list to pair them.

Some Bluetooth devices may prompt you to enter a passcode or PIN to complete the pairing. This is usually 0000 or 1234 but check your device. Enter the code if asked and the pairing should complete. Once done, your PC will show the device as connected and you’ll be able to use it for audio playback.

If the pairing fails for any reason, repeat the steps and ensure your device is discoverable in pairing mode. You can also try removing the device from your PC’s Bluetooth settings and pairing again from scratch. Refer to Microsoft’s guide for more detailed troubleshooting on Bluetooth pairing.

Set your Bluetooth device as the default playback device

Once you have paired your Bluetooth device with your PC, you need to set it as the default playback device to route audio through it. Here are the steps to set a Bluetooth device as the default playback on Windows 10:

1. Open Sound settings on your PC. You can access this by right-clicking the speaker icon in the system tray and selecting Open Sound settings.

2. In Sound settings, click on the Playback tab.

3. Find your Bluetooth device in the list and right-click on it. Select Set as Default Device from the context menu.

4. You will see your Bluetooth device now has a green checkmark next to it, indicating it is set as the default playback device.

Now when you play any audio or video on your PC, the sound will automatically be routed through your Bluetooth headphones, speaker, or other device. You don’t have to manually change the output device every time.

Setting the default playback device enables a seamless audio experience when using Bluetooth accessories with your computer. Just remember to switch back to your PC speakers as the default when not using your Bluetooth device.

Play audio through your Bluetooth device

Once your Bluetooth speaker or headphones are paired and set as the default audio playback device, any audio played on your PC will be routed through the Bluetooth connection.

To test this, simply launch your preferred music player or audio app like Spotify, iTunes, Windows Media Player, etc. The audio should automatically start playing through your connected Bluetooth device rather than the built-in PC speakers.

You don’t need to adjust any additional settings – the audio routing is handled automatically by Windows. As long as your Bluetooth device remains on and connected, you can play music, videos, games, and other media, and the sound will come through your wireless headphones or speakers.

If for some reason the audio does not automatically play through the Bluetooth device, go back to your sound settings and double check that your Bluetooth device is set as the default playback device. You may need to change this setting again if your PC has automatically switched back to another output.

Overall, once properly set up, playing audio through Bluetooth is quick and convenient. Just launch music or video as you normally would on your PC, and the sound will be wirelessly transmitted to your Bluetooth headphones, speakers, or other devices.

Manage Bluetooth Connections

Managing your Bluetooth connections allows you to view devices that are currently paired, connect or disconnect them, and remove devices you no longer want paired. Here are some tips for managing Bluetooth connections in Windows:

View a list of currently paired devices by going to Settings > Devices > Bluetooth & other devices. This will show all the Bluetooth speakers, headphones, and other devices paired to your PC. Hover over a device and click on it to connect or disconnect it.

To remove a paired device you no longer want connected to your PC, go to the Bluetooth settings, find the device, and click the “Remove device” button next to it (Source). This will unpair the device so it won’t automatically connect again unless you repair it.

You can also click “Add device” in the Bluetooth settings to pair a new Bluetooth accessory. Your PC will scan and find nearby discoverable Bluetooth devices to connect.

If you have connection issues with a Bluetooth device, you can try removing the device and repairing it again. Also check for any updates from the device manufacturer. Keeping your Windows version up to date can also help with latest Bluetooth drivers and fixes.

Bluetooth Safety and Security

Bluetooth uses short-range radio waves to transmit data between devices. The low power of Bluetooth signals limits the transmission range to around 30 feet. While this restricted range reduces security risks from remote hacking, Bluetooth connections can still be vulnerable to certain threats.

To make Bluetooth more secure:

  • Set your device to be non-discoverable when not in use so it’s harder for others to detect.
  • Use strong Bluetooth passwords and change default pin codes.
  • Only pair your device with other known, trusted devices.
  • Turn off Bluetooth when not using it to connect devices.
  • Use encryption on Bluetooth connections.
  • Install security updates for Bluetooth software and firmware.
  • Avoid using Bluetooth in extremely public areas.
  • Use a VPN for added privacy when using Bluetooth in public.

Common Bluetooth threats like bluejacking can be avoided by making your device invisible to others. Longer pin codes and device names also help enhance security. While Bluetooth has some risks, following best practices allows you to use it more safely.

Bluetooth alternatives

While Bluetooth is convenient for wireless audio streaming, there are some alternatives worth considering:

Wired audio connections

Using a wired connection like an AUX cable can provide superior audio quality compared to Bluetooth. There is no compression or loss of audio data with a direct wired connection. Simply plug one end of the AUX cable into your phone or media device, and the other end into your speaker input. This will allow high-fidelity audio playback.[1]

WiFi speakers

Many modern wireless speakers now use WiFi instead of Bluetooth for streaming. This allows for features like multi-room audio, higher bandwidth, and less interference. WiFi speakers connect directly to your home wireless network so you can stream music from anywhere in your house. Setup is easy with a smartphone app. The main downside is that WiFi speakers need power so they are less portable.
