HI have a set of blue tooth custom fit ear plugs, ought at the NEC bike show pre covid, used a few times but now won't turn on. I chatted with the guys I bought them from at lasts years NEC bike show about returning them for repair but sounds like I could end up paying close to the cost of a new set. The ear buds fit well and rather than bin them thought about making them wired only ear phones.
See photo - the bit on the left is the on/off volume & battery, the bit on the right is the bluetooth module. Thinking about having them on a 3.5mm jack plug or similar. nsuggestions on the best way to do this?
