Boom! Audio 20S Bluetooth Helmet Dual Headset Pack is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from 20S Headsets Love this headset. I use this on Multiple Bikes and it works great. I have it paired with my Infotainment System and I find it as good as my wired headset.

Rated 5 out of 5 by from You'll like it I installed the new WHIM on my 2015 Ultra and paired my 2 year old 20S. Very disappointing sound quality, It was mono and very tinny. I went ahead and picked up a pair of the 20S EVO from the dealer. Got everything set up and paired. WOW what a difference. I would have been satisfied if I was able to get stereo sound back, but there was a huge improvement in the sound quality. Even with my old system paired to my phone the sound isn't this good. It is a investment to install the WHIM and then add the HD 20S EVO system, but you will be pleased with the results. The wife gives it 5 stars also.

Rated 5 out of 5 by from Excellent Sound Quality! Well, I was skeptical but am now a believer. Expensive, yes, but the sound and functionality is second to none. I have had other wireless headsets but these provide so much more and are so much easier to use. Full Stereo High Definition sound for music and intercom. The intercom is clear and wind free. Voice commands to the Navigation and other systems is good. Remember, ONLY Harley branded wireless headsets can provide stereo sound through the WHIM Boom Box system. I tried the same headsets with the same model number from another company but currently only the Harley brand works in full HD stereo with the WHIM.

Rated 5 out of 5 by from Great way to communicate with your riding partner. Is one of the best you can get I was on the fence about these and gave them a shot so my wife and I can communicate from bike to bike. They work great! Made our recent trip very enjoyable! Over a mile range barring any mountains and such impeding the signal. She paired hers to her phone and it provided (3) easy speed dials, it worked very well. It also allowed for gps directions from her phone to go to her helmet speakers. There is an helpful app from SENA for these as well which she put on her phone. The voice activation worked great once you learn the prompts and the audio is quite clear. Unfortunately they do not pair with the Harley infotainment system but that is not an issue for me at this point. They are a Harley branded SENA 20s at a Harley premium but it played into my rewards program and was actually beneficial to pay more for them (got a $750 gift certificate coming) They are not terrible to install just be sure your helmet is appropriate for them. They fit perfect on my Shoei platinum rj open face and fit the wifes Scorpian exo gt 920 very well. SENA even makes a helmet mount for the unit that comes with a Harley 7 pin plug cord so you can hear audio from infotainment/gps through helmet speakers plus utilize the CB...I bought one through another vendor(who has great reviews of gear and such) for around a $bill and can say that it works very well also(I installed that mount on a Shoei neotech which I carry with me for inclement weather) I think an improvement would be to make it water proof as opposed to do have to watch for that within reason. For my wife and I they work and work well!

Can the helmet mounts be individually purchased?

I have two helmets and would like to install only the Bluetooth mounts to the helmets and then use the same module for both helmets. Is this possible?
Asked by: Hecster7
thanks, M2014SGS. I know this isn't a forum, but based on your reply could you articulate on the parts list or where to find them? Whether reviewing the hard copy catalog or on line store I only found the complete kits (single and dual packages) but not the individual parts?

Is the dual headset pack available in the 20S EVO version? I see it is available as a single headset.
