How many devices can be connected at once is one of the most commonly asked questions about Raycon headphones.   If you've got a newer phone from 2012 or later, you're in luck because it can hold up to 8 devices! Anything that is older than that will only be able to store 4 different Bluetooth connections.   If you want to connect more than 4 devices in total, we highly recommend getting a new phone - they aren't very expensive nowadays!
