BT RUSH is the forerunner of a new generation of intercom devices that are being developed with Midland Mesh Conference, a revolutionary chain-free technology developed by Midland. The key benefit and innovation for riders is the new style of communication: in a group of up to 10 individuals, you can enter, exit, and rejoin the chat whenever you like, in automatic or temporary connection. BT RUSH is also compatible with all BMW, KTM, and Ducati communication systems. In a Bluetooth one-on-one chat, up to four persons can participate. The range of the intercom is up to 1.4 kilometers.
