30K Bluetooth Headset & Intercom - Single

The Sena Mesh Intercom technology is now here and ready to change your ride. Simply press the button on top of the Sena 30K to turn on public mode, and you will be automatically and instantaneously connected to a virtually limitless amount of 30K users within a mile range. Intercom connections are also now more stable than ever with Sena's new Mesh Intercom technology. When one of a group's riders goes out of range, the rest of the group remains seamlessly connected while the Sena 30K still intelligently searches for the lost connection and reconnects automatically once back in range. No longer will you have to worry about losing half of your group due to a Bluetooth chain linked connection of the past. With private mode you can invite and communicate with up to 16 riders at a range of up to 2.0 km (1.2 miles), while an endless number of guests can join to listen in as well. When riding with 5 or more riders, the Mesh Intercom will intelligently keep the group connected at a range of up to 8 km in ideal riding environments (5 miles).

The technological advance of Sena's Mesh Intercom technology has the ability to work in conjunction with Bluetooth, allowing for more connections than ever before with the 30K. The Sena 30K packs all of the capability necessary to ride in large groups. Designed with an innovative dual antenna and 2 separate processors, one for Bluetooth, and one for Mesh Intercom technology, the Sena 30K has the ability to connect to each processor simultaneously with the new multi-operation feature. With the ability to dually connect to both Mesh Intercom and Bluetooth 4.1 simultaneously, the Sena 30K offers the connectivity you need while riding.
The Sena 30K's Audio Multitasking technology allows you to have a conversation via Mesh Intercom technology while simultaneously operating Bluetooth operations such as streaming smartphone music, taking or making phone calls, or listening to turn-by-turn GPS navigation. No longer do users have to deal with the frustrations of interruption-based audio functions of past Bluetooth communication devices. Now audio features won't interrupt one another but simply overlay for a smooth listening experience. Amp up your ride with interweaving audio sources.
