Making oneself heard over the roar of a motorcycle engine can be difficult at the best of times. But being heard over the roar of a motorcycle engine when tearing down the highway with your head encased in a helmet is downright impossible. Naturally technology has come to the rescue in the form of Bluetooth enabled helmets and helmet-to-helmet communication systems. The latest solution to keep chatty bikers happy is the scala rider G4 bike-to-bike Bluetooth headset that offers group intercom between up to three riders at distances of up to one mile.

As well as offering intercom conversations between three separate riders, the scala rider G4 from Cardo Systems also allows communication between two riders and their two passengers, also at distances up to one mile, depending on the terrain. With the headset offers full duplex (simultaneous talking/listening) capability as well as mobile phone call conferencing between riders, between rider and passenger, or with outside callers why would you need to go back to the office? Just hold a meeting on the road.

The G4 can connect with virtually any portable Bluetooth device including mobile phones, MP3 players and compatible GPS units for in-helmet voice instructions. Its A2DP capability means the headset can receive CD-quality music from any A2DP capable MP3 player. It can also connect with non-Bluetooth MP3 players, GPS units via its embedded jack, as well as the entire line of scala rider headsets. The unit has a built-in FM radio with RDS and scan and seek features with six-station memory.

AGC technology automatically adjusts the headset volume of audio from an MP3 player, mobile phone, intercom or GPS, based on ambient noise and riding speed. Meanwhile, PLC technology is designed to improve audio quality in dense urban surroundings. Meanwhile, VOX technology allows the wearer to make voice-controlled hands-free intercom calls and phone calls with answer, voice dial and call reject functions.

Designed to fit virtually all three-quarter and full-face helmets the scala rider G4 features a weather-resistant design and noise-canceling microphone, which is available in a corded version for full-face helmets.

The headset can be self-installed in five minutes with a glue-on option included for those not wanting to go with the clamp, which features a quick-release mechanism. The two included speakers are slim enough to fit even tight helmets according to the makers.

The scala rider G4 is available through Cardo Systems for a suggested retail price of US$279.95.
