Apparently, a firmware patch had been pushed (you cant opt out) and it has a bug that creates the issue. Great design, great quality. I ordered a size 12, but the way they fit my feet they look more like 11. I picked up playing a little more online gaming during the pandemic. I highly recommend these weights). If your cable eventually wears out, just get a new cable. The replacements arrived on the day promised and they are working fine at this point. 5 EEE foot better than expected. Just great, great engineering and tuning on these incredibly affordable TWS.
