Doesn't work with Macbooks or iPhone %26 android phones. It says it does, I followed all the steps and Googled for hours, but there's No Way to record with it because your MacBook will not recognize it as an "input" device, ONLY as an "output." This is when connecting the 'soundcard' (effects box) via USB AND Bluetooth. Might work great on Windows, idk, but I tried it on 3 different generations of Macbook, an iPhone %26 Android phone and none recognized it as a microphone or sound source (input), only as a sound destination (output, like headphones or speakers). Nothing seems to recognize this as an input device from which recordings can be made. I read the other reviews and thought everyone was a boomer, but even with tech exp %26 hours of troubleshooting I couldn't get it to record or transmit ANYTHING to another device/computer. Otherwise decent plastic quality, nice starter kit, but as A NON STARTER Don't bother, buying I'm Returning it.
