Siri is the name of Apple's personal digital assistant. Siri is voice control that talks back to you. Ask Siri questions, or ask Siri to do things for you, just like you would ask a real assistant.
Libratone Q Adapt On-Ear is compatible with this nice Apple feature.
To activate Siri on your Q Adapt On-Ear, simply press and hold the Touch Interface with two fingers for approx. 5 seconds until music stops and you hear an audio cue from your iOS device.
