The JBL Live 660NC is an over-ear wireless headphone designed for everyday use, travel, and commuting. It features 40 mm drivers with JBL’s Signature Sound, punctuated by enhanced bass, adaptive noise cancellation (ANC), Ambient Aware, and TalkThru modes, as well as Bluetooth connectivity, voice assistant support, and up to 50 hours of battery life. It also includes a detachable 3.5 mm cable for wired use and a companion app for sound customization. The headset was released in 2021 with a retail price of around $174.95 USD and was sold globally through major retailers.

This model targets users who want affordable adaptive noise-cancelling headphones without paying premium prices. Its main audience includes students, commuters, and casual listeners who value comfort and long battery life. Reviews praised its strong sound quality and battery performance, but noted that the ANC and call microphone were average. There have been no official recalls; however, some users have reported issues with Bluetooth connections and wear on the headband and ear pads over time.

The Live 660NC followed the earlier JBL Live 650BTNC, offering better battery life and improved app features. It fits within JBL's mid-range “Live” headphone series and remains popular for its balance of price and performance. Later, JBL models continued to refine this design, although no direct successor with the same name has been announced.
