I receive a pair or Prime Brands NFL ear buds as a gift. Turns out they were duds not buds. I reached out to Prime brands it took less than 3 weeks they shipped me a replacement pair at no charge. The replacement ones look more like apple ear pods.
I am hoping some one can help me fix the original ones as I found them more comfortable.
There are a few unpopulated parts I think the SOT-23 is the important missing part, I am not certain but I think it is in the negative feed from the battery.
Also if any one can point me to the data sheet for the chip may be there is a sample circuit.
JL "UEB094" I could not find the chip at
