That's twice the battery life of Marshall's previous Major III model. Despite spending several years upgrading the iconic Major headphones, Marshall announced a new set only one year after it came out with Major III.

The company's new Major III Voice Bluetooth headphones incorporate voice control from Google Assistant and a dedicated button for simple activation. The headphones still bear the control knob included with the previous model. The knob enables for replay and volume control as well as switching on and off the headphones.

Major III Voice headphones ' other major feature is much improved battery life. Marshall says that the Major III Voice can produce on a single charge a whopping 60-hour battery life.

We're going to have to see how they do in practice and figure out if the promises of Marshall are correct, but it's worth noting that we found the Major II headphones regularly delivered more than the 30-hour Marshall claimed on the packaging.

In any case, 60 hours of uptime is no small feat for a pair of Bluetooth headphones. All that extra battery life comes at the expense of an efficient noise cancelation feature. Sony, for example, says the outstanding WH-1000XM3 headphones offer up to 30 hours battery life on a single charge, but then it also costs $350 for an eye-watering.

Otherwise, Marshall delivered the same good headphones in 2018. The Major III Voice uses the same earpads and 40 mm drivers as the Major III. The aptX audio codec from Qualcomm also completes the move, providing a better solution to delay than the SBC codec which comes with most Bluetooth headphones.

The Major III Voice at $169 is $20 more expensive than Major III, but in view of the upgrades it seems like a fair compromise. The Major III Voice Marshall will be available from 16 October.
