I purchased this about a year ago, but I immediately replaced my helmet with a Neotec 3 and bought a B+COM intercom system built into the helmet, so I haven't used this and have kept it in storage. This is a domestic genuine product. I only opened the box to check the contents immediately after purchase, and I have never used it. It hasn't even been taken out of the bag. The Cardo Packtalk Edge supports Bluetooth 5.2 and features a JBL sound system for high-quality calls. - Brand: Cardo - Model Name: Packtalk Edge - Bluetooth Version: 5.2 - Sound System: JBL - Operation Method: Natural Voice - Mesh Function: Dynamic Mesh Thank you for looking.
