NEWS FLASH:
SENA has just released version 4.X firmware for the SMH10 with major enhancements in functions and performance, including Bluetooth 3.0, four-way conference intercom, multi-point connection, voice prompt and more. All upgrades are free.

Simple to use (arguably the most important of its many functions)
What sets different motorcycle intercom headsets apart is their functionality and ergonomics. Traditionally other market offerings involve a series of obscure and illogical button-pushing sequences that are challenging at best, leaving the user to ponder if they were ever designed for motorcycle applications in the first place.
Having the most bells & whistles is worthless if you are distracted through fiddling for the correct buttons. Furthermore a unit should at very least be glove friendly.
A simple rule of thumb: If you are tempted to remove your gloves or aimlessly fiddle while riding in order to do something with the unit, then that function is useless and potentially unsafe.
The Sena SMH 10 is by far the simplest intercom system to use and is designed with ease of use and safety in mind.
There are two design factors that are immediately noticeable on the Sena SMH10: first, the absence of many buttons. Believe it or not, the engineers at Sena have made a breakthrough in a motorcycle intercom user interface - A total of one button.
It's called the "Phone Button" because it controls pretty much all of the functions of a paired cell phone.
The other can't-miss feature is the "Jog Dial". The Jog Dial controls the intercom functions. The Jog Dial also rotates to raise and lower the volume. Rotate the wheel one way to raise the volume; rotate it the other way to lower the volume. Simplicity at its best.
Adjust the volume Should you not wish to use the Voice Activated
intercom (VOX) then a simple tap of the Jog dial
will activate the intercom
Many cell phones that are capable of playing music are also AVRCP (Audio and Video Remote Control Profile) enabled.
With AVRCP compatible players the unique Jog dial also allows you to control your music. Now you can even pause/play music as well as skip forwards and backwards through your play list via a simple tap of the Jog dial.
NEW! Stream the audio signal directly from your iPod/iPhone to your Sena SMH 10 and SMH5 headsets with this new bluetooth dongle with full AVRCP. More details.
