You can use your phone as a computer speaker with the help of audio streaming apps. The software installed on your smartphone and PC connects via Wi-Fi.
Android and Windows phone users can use the SoundWire Server app as a solution to connect their devices. iPhone (iOS) and Mac owners must install the Airfoil app on their devices to create an audio stream.
Both apps offer a free trial version with the basic tools to turn your phone into a speaker. Therefore, it is not necessary to subscribe to the services to get additional features.
Below, see the step-by-step guide to transmitting audio from your computer to your smartphone.

What should I do if I can’t play sound from my PC on my phone?
There are some things that can prevent sound from being transmitted from your PC to your phone. The most common ones are:
- Check your Wi-Fi connection: both your computer and your phone need to be connected to the same Wi-Fi network for streaming to work. Also, make sure the connection is stable and without interruptions;
- Audio settings: Your SoundWire or Airfoil may be set to send audio to another accessory, such as headphones or a speaker. Change the app settings and choose your Android phone or iPhone as the audio output device;
- VPN: If you use a virtual private network (VPN), it may be blocking the connection. Try temporarily disabling the VPN and see if the issue is resolved;
- Distance and interference: Move devices closer together and avoid obstacles between them. Also, check if other devices connected to the network are causing interference.
Can I use AirPlay to play sound from my Mac to my iPhone?
You can’t use AirPlay to play audio from your Mac directly to your iPhone. The feature is primarily for sending audio from your phone to other compatible devices, including Apple computers.
However, AirPlay can connect your Mac to Apple’s Apple TV streaming devices and Apple’s HomePod smart speakers. Additionally, some smart TVs support the Apple device connection format.
