How do I get anker speaker to stay connected to device and why is sound so bad when it is?
Anker speaker will not stay connected with blue tooth
More information please.
What kind of speaker & what kind of device you’re trying to connect to?
You wouldn’t go to a doctor an tell him :
“I got some pains”… nothing more 
Please provide the make and model of said speaker, the source you are connecting too and if the speaker is fully charged
what @elmo41683 said, plus in the slim chance that you received a faulty one, contact support@anker.com.
We are looking forward to hearing from you more, so that we can help you solve the issue more efficient.
