Live 660NC Noise-Canceling Wireless Over-Ear Headphones (Black)
Product Description
Stay connected while tuning out the world with the Live 660NC Noise-Canceling Wireless Over-Ear Headphones from JBL. Pumping out your favorite music through large 40mm drivers, the Live 660NC lets you listen without distraction thanks passive noise isolation from over-ear earcups and adaptive noise cancellation technology that filters out distracting ambient noise. With Bluetooth support and a built-in microphone, you can also use these over-ear headphones to connect through your smartphone. Take hands-free stereo calls or tap the earcup to engage your device's digital assistant. If it's Google Assistant, simply say "hey, Google" to activate it by only using your voice. All of this and more is possible for up to 40 hours with ANC & Bluetooth on, or up to 50 hours with ANC off.
