Nolan N-Com B4 Bluetooth Kit for N104, N44 and N40 Helmets

The N-Com B4 is the revolutionary N-Com® communication system, specifically designed for the N104, N44 and N40 helmet. The innovative installation system mounts between the helmet shell and EPS liner by simply releasing the shell sealing edge and inserting the N-Com® B4 (see updated installation notes from Nolan here). Traveling by motorbike is now all the more pleasant: with B4 it is possible to communicate with 4 motorbikes up to 500 meters (in open terrain, with no obstacles), listen to the integrated FM radio, and set up the system easily with your PC from home. The B4 can be upgraded to the B4 PLUS via Firmware version 4.02 (download from N-Com Wizard).

Nolan N-Com B4 Bluetooth Kit for N104/N44/N40 Helmets 3.6 5 34 34
Easy to install, Great fit into helmet This was easy to install and the allen wrench was included. Liked the fact that there was a small extension wire for easy hookup. May 14, 2014
Good Compatability Excellent integration with the N-104 helmet. Bluetooth connects easily with my Garmin GPS, IPhone - phone and streaming music, and my Triumph Trophy SE. Audio quality is excellent for rider/pillion and phone communications. Good quality for music. April 6, 2014
Wouldn't buy it again The unit installs easily. I have owned for about a year and am disappointed with the performance. When changing function or stations, the "beeps" jump around and are unpredictable. Sometimes I can access my phone, sometimes not. At highway speeds, noise from my helmet makes it difficult to hear. I cannot download updates or work with the program because it is PC based & won't work with my MacBook Pro or iPad. Selection of stations is ok in the city but on highways away from urban areas it is not uncommon to get no stations at all. I have had some success with phone apps like TuneIn but reception is inconsistent. Overall, this has been more trouble than it's worth. Save your money! March 24, 2014
This Bluetooth kit is easy and has great functionality. It's great. It only has three buttons so you don't have to jumble around with controls while you're riding. It's really easy to learn to program it and even easier to switch from radio to Bluetooth music from your phone to answering a call. Has great battery length lasting almost 4 hours of nonstop playback January 6, 2014
Really Interesting I never expected the B4 to be as effective as reported. Very clear sound up to 800+ meters away. Ones paired, automatic connection eliminates the need to ask the either the phone or the B4 to connect each time. Astonishing noise deduction from surrounding wind, from the other rider (Bike to Bike) and while making a phone call. Simple to use controls, you will not feel it in the helmet, you just know it is there. January 4, 2014
The Nolan N-Com B-4 really works! This really works and easy to in stall. The clarity for voice recognition is great, clear and with no interference. The person I'm talking with can not tell I'm on my motorcycle. Controls for volume and channels are intuitive and quick to operate while in motion (Please use caution). This takes the worry out of staying in touch! October 28, 2013
Good helmet for the amount of money spent. Great helmet. Bloototh works great. Just battery doesn't hold as much as others. October 24, 2013
excellent choice again, product works as advertised. Nolan built this for the rider! October 14, 2013
