1.The biggest difference is we changed the Bluetooth connection solution for MindWave Mobile plus to improve overall stability. It uses BLE for iOS platform so some old iOS apps may not be compatible with the plus version.
2.The MindWave Mobile plus has no pairing mode so it helps our customers simplify the connection steps.
3.The MindWave Mobile plus can be used in both 50 Hz and 60 Hz regions but the old MindWave Mobile is designed and intended only to be used in the country they were purchased in.
