Refurbished Apple iPad and iPhone - iOS 9 tip: How to launch Siri hands-free - buyEtail.com

if you have a new iPhone 6S or 6S Plus, you can now say, “Hey Siri,” anywhere, at any time, and Siri will respond. In iOS 8 this was only possible when your iPhone was plugged in and charging, which is unfortunately still the case for the iPhone 6 and below. Go to Settings > General > Siri and toggle Hey Siri on. You’ll do a quick spot of training to ensure that Siri only responds to your voice, and then you’re good to go.
