First, the Major III features new earpads alongside changes to both the headband and hinges. Marshall says these tweaks make the headphones more comfortable so they can easily be worn for long periods of time. Of course, we have to take their word for it right now, but the Major II was quite comfy during our time with that set. The same guitar gear aesthetics that are a trademark of Marshall's audio gear are here once more: a mix of black vinyl and leather, gold accents and that iconic script logo.
Next, both versions of the Major III pack in updated 40mm dynamic drivers for improved sound. Marshall says the tweaks translate to more clarity without sacrificing low-end oomph. We were quite pleased with the audio on the Major II, so hopefully the changes here only made a good thing even better. On the wireless Major III, Marshall kept the stellar 30-hour battery life from the previous version. That's at the high end of play time for wireless headphones I've tested recently. What's more, we managed to get 37 hours out of the Major II, so that 30-hour rating could be a mark you easily surpass. Again, another item we'll need to test during a full review.
Perhaps the best thing about the new Major III is the price. Marshall didn't hike up the invest here as the wireless Major III is still $150 (€150/£129) while the wired version is $79 (€79/£69). Both are on sale now, so you won't have to wait weeks or months to try them for yourself.
