I tried a search but couldn't seem to find anything. After doing some research I've decided to go with the Sena headset...then I see that they have a SMH5 and and SMH10. I looked on their site but I'm still not sure what the differences are. I was hoping that someone who is familiar with both could chime in. Can I plut in regular earbuds into either of these systems? I'd prefer to use noise cancelling earbuds instead of using the provided headset and earplugs. Any other major differences? I'm assuming bluetooth 3.0 is better than 2.1? Thanks!
