Thank you for viewing. This is the [Zenchord 1], the first AI earphones equipped with Notta's voice recognition technology. I purchased it on the crowdfunding site Makuake. I opened the box and used it for online meetings for about 1 hour, 3-4 times, but the open-ear type didn't fit my ears, so I'm putting it up for sale. I was satisfied with the accuracy of the transcription of notta itself, but it didn't fit my ears. I would like to sell it to those who are already using notta, as well as those who are considering AI earphones. All accessories such as the instruction manual and charging cable will be included.
