A:Answer Hello Wayne, thank you for your interest in the SoundLink Revolve+ Bluetooth speaker! To provide some clarification, the system does include a 3.5 mm auxiliary audio input. Once you connect an auxiliary cable from your device's headphone jack to the AUX IN port on the Revolve+, you can tap the Input button on the top of the speaker to change the source of your music from Bluetooth to AUX. This button looks like a circle with an arrow going through it. Hope this helps! Jesse - Bose Support
