Sadly, a bunch of cheaper self powered speakers get flaky. I guess you really do get what you pay for.😕 when you see the markup on products it’s not surprising. The manufacturer designed, built, designed the packaging and shipped their products for a dollar and makes money from each item sold. They set a list MSRP @ $2. For the manufacturer to do all that for their wholesale price and shipping, they have to be using lower QQ and less expensive parts and labor.
