@Brandon23nguyen Rave Neo supports Dual Bluetooth Connection, that is, it can pair up to 2 mobile devices via Bluetooth. However note that the speaker can only play music on one mobile device at a time.
I am writing this based on my experience with Rave Mini and i am sure this works for Neo too
If you have one smartphone already paired to Rave Neo then follow the below.
To pair with another Smartphone / Bluetooth device , press the Bluetooth button on Rave Neo to re-enter Bluetooth pairing mode.
Follow the regular Bluetooth pairing process on your second Smartphone / Bluetooth device and make sure it pairs to Rave Neo.
After this each time you power on your Soundcore Rave Neo (Rave Mini in my case) , it auto connects to last connected device if available within the Bluetooth range of the device. If it does not, then press the Bluetooth button to enter Bluetooth pairing mode.
Please give it a try and let me know.
