JBL Live 660NC Wireless Noise Cancelling Over-The-Ear Headphones

Our review of the JBL Live 660NC finds these wireless over-the-ear headphones best suited for commuters and desk workers who want strong noise control and long runtime without spending new-product prices. The biggest reason to buy is the combination of effective Adaptive Noise Cancelling and a familiar, punchy sound signature driven by 40mm drivers, which together deliver focused listening in noisy environments. As a renewed unit they offer solid value, though potential buyers should weigh mixed reports on long-term build comfort and durability.

Key Features

• 40mm Drivers: Deliver a lively, venue-style sound signature that emphasizes clarity and punch for popular music genres.
• Adaptive Noise Cancelling: Helps block background noise for focused listening during commutes or in open offices.
• Ambient Aware and TalkThru: Let users hear traffic or hold conversations without removing the headphones, improving safety and convenience.
• Voice Assistant Integration: Use your preferred voice assistant hands-free or via a tap to manage settings, calls, or playback.
• Long Battery Life: Up to 50 hours of playback on a single charge and a 10-minute quick charge that provides about 4 hours of use.
• Stereo Call Mic Tech: On-ear controls and mic setup let you manage calls with decent clarity for phone and video calls.

Who It's For

The Live 660NC is ideal for commuters, frequent flyers, and office workers who prioritize noise cancellation and long battery life over boutique materials. Renewed units are a sensible choice for shoppers who want JBL sound and ANC at a lower price and are comfortable with a pre-owned condition guarantee.

Those who demand the absolute best in long-term build robustness or premium fit may want to consider higher-end models with metal headbands or thicker earcup padding, since customer feedback on comfort and build quality is mixed and a few units have shown durability concerns after months of regular use.
