Sennheiser xsw-d battery replacement
Sennheiser xsw-d battery replacement and battery life. Advertisement says up yo five hours, but usually I'm spectic and and I assume 2/3 when battery operated product is quite new. And later, after couple of years I assume about half of the original advertised time.
Anyway you need to change the batteries if you want to keep original design of this product. And when you've had enough of changing the battery, later you'll perhaps end up with power bank solutions.
You must use safety glasses!
