Our Verdict
JBL Quantum 800 Wireless
JBL Live 660NC
The JBL Live 660NC are better over-ear headphones than the JBL Quantum 800 Wireless. The 660NC are better built, more stable, and have a more neutral sound profile out of the box, which some users may prefer. They also have a better battery performance, and their companion app offers a parametric EQ and presets. However, the Quantum 800 have a better-performing ANC.
