Very Disappointed in over the road performance!
My riding buddy Tom and I bought a pre-paired set of Sena 20S Evo's from Cycle Gear. They installed one unit into a new Shoei helmet I also bought at the same time.

Set up pairing and I tested out sound quality of the Blue Tooth connection to my phone by playing a YouTube video.

Sound quality was good if not excellent as I’m comparing to a set of Polk Audio ear buds I use when connected to my computer.

My other basis of comparision was the Bilt helmets I bought several years ago from Cycle Gear with Blue Tooth communication built in.

These were extremely fiddly and a real aggravation to pair up once they were turned on.

Sound quality in the Bilt was average to poor, but range was a true half mile and did not depend on line of sight. On-air time was a true 8 hours.

Sena 20S Evo:

Blue Tooth pairing to my Apple smart phone. Simple and immediate. Sound quality is good to excellent at least while not in motion.

Sound quality is good in motion. Tested Google Maps turn by turn GPS instructions and sound quality was good at speed—about 55 mph.

Blue Tooth pairing to a pre-paired set. Almost immediate. Sometimes takes two attempts. Also, connection quality is intermittent.

It may take two attempts (or more) of powering down and re-pairing to establish a good connection. Aggravating.

Boom microphone: average to poor sound/transmission quality and very fiddly and dependent on position in relation to mouth and lips.

Remote microphone: in this case, I went with the remote mike which is fixed to the inside of the chin bar. Tom couldn’t use this because he had a modular helmet.
Evidently this has excellent sound quality as Tom always heard me crystal clear—as long as we had true line of sight (more on this later).

Sound quality improved somewhat by installing the speaker spacers in the helmet ear pockets. I tried the thinner spacer, and then the thicker spacer. Thicker spacer improved quality but also mashed my ear somewhat, causing some discomfort.

We bought these primarily for bike to bike communications. The rest of it for us is “nice to have” (blue tooth to phone, GPS, etc., etc.) but not the primary reason to purchase. We wanted simple, clear communications and a very minimum of fuss and fiddle. We also wanted good to better range as the Evo was touted as up to a mile and a half. Ha! This is nonsense.

This is not the case as noted above. Less fiddly to pair up compared to the Bilt helmets. Still a little fiddly and connection quality varied every time we paired up.

Worse, pairing distance is abysmally limited and fully dependent on full line of sight between riders. Even a dip in the road will cause loss of connection momentarily.

Best connection was when I could literally see Tom’s helmet and chest and at least most of his bike in my rear view. Anything less, and we lost connection.

Even in full line of sight, distance was maybe a quarter mile and any rounding of a bend caused immediate loss of connection. Connection came back when we had full visibilty of the other rider.

Connectivity is very linear—it is either there or not there at all. There is no in between where there may be some fade or static, but you can still detect the other person (as in the Bilt helmets).

We don’t know actual on-air time as we never had these on past 8 hours. It is touted as 13 hours, but we don’t know first hand.

Overall, I would rate these about two stars out of five as we both were coming from the Bilt experience and expecting MUCH better performance!

I am disappointed, but not so much that I would return them for a credit, only because of the aggravation involved. And, I wouldn’t consider another brand as I don’t think performance would be any better and I don’t want to go through the additional aggravation of a helment de-installation and reinstall and testing of something else.
