No LED to indicate the the speaker is currently on / off. Speaker has bluetooth but fails to connect more often than it connects. When the speaker does turn on the sound can be heard throughout the house, so it's really loud ... but there doesn't appear to be any way to turn this part down. So, if it has connected to bluetooth (phone) and you walk around the house while taking the call, there is a really loud connection sound that sounds every time it finds your phone again.
