headphones offering different benefits. The JBL Live 670NC features active noise cancelling for a quieter listening experience, especially useful during air travel or in noisy environments. It has a longer battery life and supports wireless charging, making it convenient for extended use without frequent recharging. In contrast, the Marshall Major IV is praised for its overall sound quality, with a reputation for delivering excellent audio. It has a different style of integrated microphone and is known for its durability. Both headphones are on-ear, closed-back and can be used wired or wirelessly. The JBL's sound quality is generally considered poorer, which might detract from immersive music or video experiences, and it is not optimal for gaming. The Marshall, while lacking noise cancellation and advanced features like app equalization, may appeal to those prioritizing sound quality and simplicity in design over tech features. Choose the JBL if noise cancellation and battery life are priorities, or the Marshall for superior sound and simplicity. Give Feedback

Sound Guys

Jasper Lastoria | September 2023
"The Marshall Major IV shares quite a bit in common with its predecessor, but a key upgrade appears to be softer ear cushions. They make upgrading worth it. As a set of basic wired or wireless headphones the Major IV ticks most boxes by remaining easy to use, and fairly comfortable (at least, as on-ear headphones go)."
