The JBL Tune 660NC is a wireless headphone model that comes with active noise cancellation (ANC) technology. It offers good sound quality, comfortable fit, and up to 44 hours of battery life with ANC turned off.
If you are looking for headphones primarily for their noise-canceling feature, then JBL 660NC can be a good option. It effectively reduces background noise, allowing you to fully enjoy your music or calls without disturbance. The comfort and long battery life are additional attractive features.
However, if you prioritize sound quality and audiophile-level experience, there might be better options available in the market at a similar price point. It's important to consider your personal preferences and requirements before deciding if the JBL 660NC is worth it for you.
