JBL Tour One M3 vs Marshall Monitor III ANC

Buy the JBL Tour One M3 if you want the most features: a built-in DAC for lossless wired listening, Spatial 360 with head tracking, a bundled Smart Tx transmitter for in-flight systems, and Auracast sharing. Buy the Marshall Monitor III ANC if you want the longest battery life and a simpler, sturdier-feeling headphone with a foldable build and hard case. The JBL has more going on and more that can go wrong; the Marshall has fewer moving parts and higher owner ratings, though from a much smaller sample.

• Choose the JBL Tour One M3 if you want lossless audio over USB-C, spatial sound with head tracking, and a transmitter that plugs into plane and gym entertainment systems.
• Choose the Marshall Monitor III ANC if battery life matters most and you want a foldable, hard-case headphone with a physical control knob and no app required.
