It depends on how you decide to use headphones LAmax Dots1.
Depending on your needs can be deployed both classic and still only one that I noticed what was going on around you. Here's the breakdown of the various combinations and endurance:
Up to 3 hours - if you put two (stereo)
Up to 6 h - if you use the headphones to the bench (one handset lasts 3 hours)
Up to 30 hours - if you're in the field with a charging box (15 h in stereo mode)
It's a lot of numbers, but the possibility of use is simply a lot. It's up to you how you use LAmax Dots1!
