With the Marshall Major V Cream, you can listen to music for days without problems. Thanks to the 100-hour battery life, the battery of the headphones rarely runs out. If the battery does run out, you can charge it in 15 minutes for 15 hours of extra battery life. You can connect the headphones to your smartphone, tablet, or laptop in 2 ways: via Bluetooth or with the included audio cable.
