The JBL Tune 660NC are wireless, on-ear, active noise-cancelling headphones that deliver JBL's renowned Pure Bass Sound in a lightweight and compact design.  With up to 44 hours of battery life with active noise cancelling (ANC) on, or up to 55 hours with Bluetooth only, the JBL Tune 660NC provide long-lasting listening enjoyment.  The headphones feature convenient USB-C charging, allowing you to get 2 extra hours of playtime with just a 5-minute charge.  For wired listening, the JBL Tune 660NC come with a detachable audio cable. 

The active noise cancelling on the JBL Tune 660NC effectively reduces low and mid-frequency ambient noise by up to 10dB, making your music sound clearer and more immersive, even in noisy environments. The on-ear, flat-folding design makes the headphones portable and easy to carry around.  While the all-plastic construction keeps the weight down to 166g, it does mean the build quality is not as premium as some higher-end models. 

The JBL Tune 660NC connect to your devices via Bluetooth 5.0, with support for SBC and AAC codecs. Bluetooth multipoint allows you to pair the headphones to two devices simultaneously, making it easy to switch between your smartphone and laptop. Physical controls on the right earcup provide intuitive access to volume, playback, voice assistant, and ANC functions. 

Overall, the JBL Tune 660NC offer excellent value, delivering wireless connectivity, active noise cancellation, and impressive battery life in a portable on-ear design.  While the build quality and feature set may not match premium headphones, the Tune 660NC provide a great listening experience at an affordable price point.
