For over 5 years, I spend about 5-10 hours a day using headphones via the Roku remote. [Part of the 5-10 hours a day is listening to all night radio via the Tunein radio channel]
How often do you have to use new batteries (or recharge them)?
UN-Rechargeable batteries last 1-4 days
Rechargeable Batteries need to be charged about every 4 days when new, than quickly to 3 days, than 2, than down to daily. Lasting about 6-12 months.
When buying new re chargeable batteries, 'Pre charged' rechargeable batteries do not seem to last as long as non-pre changeable batteries.
