Sounds Clear to me

Helmet installed into: Giro Seam

I've been using the Sena SPH10S for a couple months to try all features in different conditions.  

Set up:

Installation and pairing was easy which is a big plus for those who aren't as tech savvy and want the convenience of a blue tooth head set. 

Use:

During initial use, the pairing kept dropping signal, which was frustrating, but uninstalling and reinstalling seemed to fix the issue.  After getting the pairing issues sorted out, I made a few calls and used the iPod on my phone and was quickly impressed with the clarity both from the iPod and from the phone conversation.  Philpug used the second Sena to talk on the phone to test the microphone/phone clarity.  I was surprised at the quality of sound from his microphone even while in strong winds.   Big thumbs up for the microphone!

Next up, we tried the intercom feature:

The intercom is handy and does an auto search when out of range, to find the other "paired" user when he/she is in range, which is a great feature, as long as you don't run the battery down trying to search for the other user.  The range is pretty good(not sure of the distance) as long as you're in line of sight which is pretty handy when doing video for ski clinics, which is something that we do quite often. 

If I had one complaint about this particular model it would be the knobs and buttons, as they are not intuitive to use.  

With three buttons and one dial, I had to think about which one to use for the task I was trying to access. 

All in all, this is a great bluetooth for day to day use, and I'd highly recommend it for someone looking for bluetooth convenience in their snowsports helmet.
