Turns out you can in just a few simple steps.
Yes, you can use your Android phone as a speaker for your computer, even a cheap phone. At this point the real question should be what can't you do on your Android phone, but that's beside the point. Using your Android phone as a computer speaker is probably easier than you think, but you'll have to install an app on both your PC and your phone. It's a good temporary fix if your computer's speakers developed an issue, and it's one of several ways to reuse your old Android phone instead of forgetting it in a drawer.
For this guide, we'll use the AudioRelay app (though there are other apps available), which works by streaming the audio from your PC to your Android phone over your Wi-Fi network, not Bluetooth. AudioRelay works on Windows, Mac and Linux. If you're wondering why regular Bluetooth pairing doesn't work, it basically comes down to how even the best Android phones are mostly set up to act as the source of a Bluetooth connection, not the receiver.
First, install the AudioRelay app on your computer and your Android phone. Depending on your computer's OS, you might have to take a few extra steps to run AudioRelay.
