Like many here, I couldn't find a replacement mic for my HS70's when it quit working. I ordered what I thought would be a replacement mic off E-bay and it didn't work. When trying to return, the seller "tommystore2013" said there was another one that would work and sent me a couple free of charge that match the OEM almost perfectly. Only difference is the tip, plug is the same. They work great. He said that the brand name of their mics are TNE. Impressed me enough to come post here for the many others like me looking for a replacement. I thought I was screwed.
