The battery lasts forever and the Bluetooth connection is very reliable

This is an amazing product from samson great sound inbuilt battery which last more than 18 hour easily plus wireless mic

The battery still charges well and holds its charge for as long as we need it

I got mine today and was so disappointed to see that you used lead acid batteries

Fantastic sound, unmatched battery life, portability, cost, flexibility in being able to connect 2 wired, 1-2 wireless and also bluetooth at the same time.
