Buy a SMH10! It actually works very close as described.
All kidding aside, the SMH10 had some growing pains when first released, but nothing like this 20S POS. I am SO GLAD that I took the advice of a Sena rep (Dean), and did not opt to 'downgrade' to the 20S.
I expect to see eBay flooded with cheap used Sena 20S units, when the Scala Cardo PackTalk Headset is released (eta in a few weeks). As long as it too does not have these issues. Hopefully Cardo (Im SURE they have) has been keeping up with the problems/issues with the 20S disaster.
