I've sold off all my wired IEMS so this is the last item to go. Barely used ES100MK2. I'd guess maybe a dozen charge cycles on the battery. I bought it right before the pandemic and then stopped commuting to work, then switched to TWS so it was barely used. Also included is the .5m short MMCX cable which IMHO is a necessity.
