Itll even last for another couple days before I have to consider charging the device. I sprayed a quick clear to seal them. So much more comfortable than normal birkenstocks. These were incredibly easy to put together! I drilled two holes with a 1-1/4" hole saw. this receiver allows me to use some trigger systems I have on hand already Can still be attached, but might be uncomfortably low for both parent and kid. Normally listen to music and youtube videos/ podcast. Out of 10 Id say an 8. Bead get easily mixed around from their boxes but other than that love these.
