The power cord plug socket has become unusable (loosened by use). Is that repairable?? Small portable Bose speaker. Thank you
@harlemjules looks repairable but we may need to see more pictures of the actually damage. Your speaker is a Soundlink Color and you can use the guides on here Bose SoundLink Color Repair or this video to work on it. Looks like a micro USB connector that may need to be replaced.
