For those interested in purchasing, I'm willing to offer a small discount! - Brand: Jabra - Model: Stealth UC - Accessories: Quick Start Guide - Case: Storage case - USB Adapter: Included USB adapter I opened the product and tried to set it up, but I couldn't get it to work properly. Therefore, I haven't used it and have kept it in storage. Although it's practically new, it has been opened, so please refrain from purchasing if you are sensitive to this. I will ship anonymously, with simple packaging, using either Rakuraku Mercari or Yuuyu Mercari delivery services.
