About this item

The JBL Live 660 NC Bluetooth headphones fit snugly and feature noise-canceling circuitry that adapts to external sounds.
Noise-canceling Bluetooth 'phones with a lot to offer
JBL always seems to deliver solid headphone performance (and include plenty of features) at a reasonable price. The lightweight Live 660 NC headphones play music wirelessly and use adaptive noise-canceling circuitry to knockout distractions. And the 40mm drivers are designed to deliver JBL's crowd-pleasing sound.
Bluetooth 5.0 is on board, which is a newer version of the popular wireless technology. That means a stronger, more stable connection for playing music and podcasts from your phone.
Long-lasting battery life
The built-in rechargeable battery gives you up to 40 hours of playback when using Bluetooth and noise-canceling. Or using Bluetooth only, you get up to 50 hours between charges — very good for the category. If you ever run out of battery power when you're on the go, the included 3.5mm headphone cord lets you listen in "passive" mode for as long as you want.
Strong sound for music and more
These headphones are tuned to deliver a mids-forward sound with clear vocals that plays well for both tunes and podcasts. They also serve up deep, punchy bass.
JBL's special headphone sound signature has been honed by years and years of research and exhaustive user testing. We've visited their U.S. headquarters in California and seen their impressive testing facilities — they take this stuff seriously. It's helped them develop a sound profile that's been proven to satisfy most listeners.
Some cool extra convenience features
JBL added some nice touches to make these Bluetooth headphones extra-useful. Use buttons on the left earcup to access the Google Assistant or Amazon Alexa through your smartphone, then just speak your commands. You'll set up the voice control assistant of your choice using the company's free My Headphone app.
These headphones also come with an Ambient Aware mode, which uses the built-in mic to increase the volume of ambient sounds. That helps you stay aware of what's going on around you. There's also a handy TalkThru mode that reduces the volume of the music, so you can have conversations with others without removing the earbuds.
