Using your Beats Solo Pro headphones is a breeze. To turn them on or off, just unfold or fold the headphones. You can switch between Active Noise Cancelling (ANC) and Transparency mode according to your needs. If you want to focus on your music without external distractions, use ANC. When you need to be aware of your surroundings while listening, switch to Transparency mode. The on - ear controls make it easy to play, pause, skip tracks, answer calls, and use voice commands. You can say “Hey Siri” to control various functions hands - free. For charging, use the provided Lightning to USB - A charging cable. When the battery is low, a 10 - minute charge can give you 3 hours of playback. You can enjoy up to 22 hours of listening time, or up to 40 hours if you turn off ANC and Transparency mode. Keep in mind that when using Audio Sharing, make sure both sets of headphones are compatible. To maintain your headphones, store them in the carrying case when not in use. Wipe them gently with a soft, dry cloth to keep them clean. Avoid exposing them to extreme temperatures and moisture, as this can damage the electronics and the sound quality.
