Well I didn't know about the 3S until you pointed it out.
I've been looking at the 3S-W through the day . . . . I really like the size and the price. It's probably all I really need . . . . . but that's it like at speed.
There's a guy on YouTube with a series of demonstrations about SENA 30K vs. Cardo PACKTALK.
I'm much, much more of a solo rider than a group rider. So the mesh network
is not the main selling point for me what has got me going
is the YouTube clip about cancelling wind noise: https://www.youtube.com/watch?v=sN4M...TuxTTV&index=4
I like to cruise in the upper KPH range
. . . . as much as I can get away with.
What's your experience stgatev of hearing the 3S above the wind noise?
I use the Sena 3S for music, navigation, and radar detector warnings. I wear Arai helmet, which are not known for quietness. I also wear quality, well sealing earplugs. I can still hear the music and voice at 80 mph. It is my first and only helmet speaker system, so I cannot compare the sound quality to other systems, but to me it is adequate. I can use navigation, take calls, listen to tunes, get radar warnings, etc. while riding, with my phone sitting in my backpack.
I have not tried the rider-to-rider features, as I mostly ride solo, so I cannot comment on that. I believe there is ability to pair to other intercoms, as well as use the Sena rider app, but have never attempted either.
I bought a "supplies kit" (velcro and double-sided tape) when I moved the system between helmets. It costs $3.95. I also got a magnetic micro USB charging adapter (Wsken brand) as to not damage the port while charging. I have not ran out of juice while on the ride. My guess is that the battery will last about as long as your phone's, and I recharge it after every 2-3 hours of active use.
All in all, a very inconspicuous little system, very usable. I am currently shopping for a new helmet, and have not even for a moment thought about installing a different set of speakers into it. I guess that confirms my confidence in the 3S.
