By using Amp me you can connect multiple devices and play the same music across all the devices seamlessly to create your own loudspeaker .

Since every smartphone in these days comes with stereo speakers the sound is pretty amazing . If it's paired to more than 4 devices then app supports for music library , YouTube & Spotify .

To create an amazing experience moreover you can also sync it with your Bluetooth speakers so that you can party anywhere with just your phone however you should be connected to same WiFi network .
