Introducing the Whisper Active Noise Cancelling Headphones by Altec Lansing. Keep the music in and outside noises out with the built-in active noise cancelling technology. Designed for everyday use, these headphones feature soft ear cushions and a foldable design to make them perfect for travel, work from home video calls to just casual music listening. The Whisper Headphones have a 12 hour battery life which means all day music listening at your fingertips! With music controls along the earcups, switch from track to track or answer/decline an incoming phone call in a breeze. Just Ask allows you to use your Siri or Google voice assistant to make phone calls, send texts, and more! We recommend fully charging the headphones before initial use for best performance, approx. 2-3 hours. To pair the headphones press and hold the power button for 2-3 seconds until you use lights flashing red and blue. From your device select ‘AL Whisper’ and pair. The lights will turn blue and flash slowly once paired. The Noise Cancellation button is located next to the volume controls. Press this button to turn on the feature; the LED indicator will turn green while ANC is on. The built-in microphone will allow you to talk to Siri, Google Assistant or use for phone calls.
