I purchased some speakers just under a year ago.
Have never been happy with them. They have a buzzing sound when on. Had I known about this I would not have purchased. The ultimate ears speaker I was trying to replace has great sound and no buzzing.
I stopped using them a while ago but haven't gotten around to trying to send them back.
How long is too long to send something back for a refund?

Have you tried anything to address the buzzing sound? A buzzing speaker is not necessarily a fault with the speaker. Could be crappy cables that are at fault, or you have other stuff causing interference. Like bluetooth transmitters or dongles.
