I have the SMH10 as well as several other Bluetooth ear pieces which I've tried on my urban & highway commutes over the years, most notably the Jabra BT3030
, Plantronics M1100
and Jabra Storm
. SMH10 was a great buy 4 - 5 years ago but it's not as rainproof as Sena would like to portray and battery life was a bit of a hit & miss. The new 20S
is the one to go for in that category. Recently Sena announced that their headsets can now communicate with other brands headsets too with a simple firmware update, which is a great move.
In my experience, Sena and Scala Riders's type of headsets are great for group & pillion riding because of their conferencing features & extended range, especially in areas where there is poor or no cellphone coverage. For solo urban commutes, the normal ones I mentioned are good enough, especially the ones with voice commands.
Webbikeworld reviewers seems to think that the new, simpler and cheaper Sena 3S
is just as good as it's bigger and more expensive siblings and I'm thinking of trying it out soon.
