My friend Glen & I used the SENA SMH10 on both our Trans Labrador Hwy ride in 2011

http://www.webbikeworld.com/motorcycle- ... ica-trail/ last summer & will be using it on our trip to tackle the western 1/2 of the TAT in 3 weeks.
The system worked flawlessly on both trips with great battery life. Range was very close to the 900 meters (LINE OF SIGHT) they claim. The only problems we had with it were:
-You have to make sure the boom is facing the correct direction otherwise the other person hears a LOT of wind noise (I had to constantly remind Glen to check his mic)
-It's rather easy to press the "Jog" button/wheel & terminate the conversation. What then happens is you both start pressing the jog button to re-connect & get out of sync
-The vox delay is too long if it's used in an emergency. Just keep the intercom "open" all of the time.
-Make sure BOTH operators KNOW how to operate their device. On several occasions I had to flag Glen down to get his straightened out because if it didn't work immediately he'd start pushing buttons & end up in the "set-up" mode or something.
-The "firmware" that was installed after the TLH & prior to the TAT had an
awful "twanging" noise when you got to the limits of the range. THANKFULLY, this has been fixed with they're most recent update which I loaded last week
My wife & I are now using it as a rider to passenger system & are thrilled with it. No more wires hanging around which she would frequently catch with her foot, disconnecting it as she got on or off the bike. It has more than enough volume to overcome earplugs too. I can't really speak for pairing other devices other than other the 2 units I have & my phone, which I have never used while on the bike. But what I've heard is all good.
