lightweight neckband design conforms to your body for all-day
wearability, and a Bluetooth connection keeps the wires out of your
way.Be the master of your environmentListen like never before with new
breakthrough technology: now you can control how much of the outside
world you want to let in. Noisy commute to work? Block out the
distractions. Waiting at the terminal? Let some in, and catch your
boarding call. Then turn it back up after takeoff. Throughout the day,
noise won’t get in your way. Unless you let it.Ergonomic neckband
designA lightweight, contoured neckband conforms to your body. It’s
designed with soft materials to stay comfortable—perfect for listening
all day.Active noise reductionNoise is a constant. So we have a precise
arrangement of microphones inside and outside the earbuds to
continuously measure, compare and react to it. The system then produces
an equal and opposite signal to cancel the noise. The StayHear+ QC tips
also form a gentle seal for additional passive noise reduction.Wireless
sound without compromisesLeave the wires behind—without sacrificing
performance. The volume-optimized EQ delivers consistent, balanced sound
at any volume. If you’re on a busy street and need to turn it up, the
sound stays true to your music. And they’re re-engineered with Bluetooth
and NFC pairing, so connecting to your devices wirelessly is quick and
easy. An inline remote lets you take/end calls, skip/pause tracks and
control volume without reaching for your device. So you can focus on the
music.An app can make the differenceWe want you to get the most out of
