I tend to use one earbud at a time for multiple reasons.
1st of all noise canceling is very good.
2nd , with one I am able to still hear others and communicate.
3rd, using for such long periods at a time I am able to get well over the 24 hours of use by using one bud at a time and recharging each from the case at least 2 times. Although to be as helpful as possible I will tell you I’ve only had these VISTA 2 wireless earbuds for approximately 2 1/2 weeks. I hope this helps and answers your question.
