JBL Tune 660NC wireless headphones

The JBL Tune 660NC are wireless on-ear headphones finished in black. They deliver JBL Signature Sound through 40mm drivers and feature Adaptive Noise Cancelling to reduce unwanted background sound. Smart Ambient technology adds Ambient Aware and TalkThru modes so you can hear surroundings or chat without removing the headphones. A tap on the ear cup activates your preferred voice assistant for hands-free control.

Upgrade from passive on-ear models

Moving to the Tune 660NC adds active noise cancellation and adaptive ambient modes that basic passive headphones lack. The jump is worth it when you regularly commute, work in open offices or travel and need to suppress low-frequency drone without sacrificing awareness of announcements or conversations. Buyers who only listen in quiet rooms will not benefit from the extra electronics.

50-hour battery life under ANC

With Adaptive Noise Cancelling active the headphones run for up to 50 hours on a single charge, so a typical work week of daily use is covered without mid-week recharging. Extended sessions stay consistent because the large 40mm drivers maintain output without thermal throttling. Users who need multi-day operation between charges will find the endurance adequate for long flights or back-to-back meetings.
