You’re welcome to listen longer
Once you listen to the MOMENTUM Free you are not inclined to stop any time soon. Not least because of the supreme comfort the included ear adapters – in four different sizes – provide. Ensuring a snug and secure fit they also block ambient noise quite effectively. Accordingly, the battery lasts for six long hours of listening pleasure. It can be charged via the supplied USB cable.
