I have the sena 20s Bluetooth kit and is superb,had the wired autocom for years and always thought that was pretty good but as soon as I started using the sena it certainly put the autocom in the shade
As Al said, I wouldn't entertain a wired setup, so old school, I have the Interphone F4 system which I reckon is probably ideal for your req's, you can buy a twin pack for very reasonable money, and the clarity is excellent up to and including illegal speeds.
The Sena units are a step above again being bluetooth 4, but have capabilities that are way more than you will ever use given your stated req's
As long as you avoid the cheapo chinese units and stick to the likes of Interphone (Cellularline) Scala or Sena then you can't go wrong

We have the SMH10. Decent bit of kit and easy to operate on the move, only 2 buttons. Friend has a Scala and he rates it highly. What is a very handy feature of BT headsets is the range they now have. Sena claims 900m.
We stop at a petrol station. Missus gets off and go inside while I refuel the bike. She asks what I want to have and I let her know what the bill for the fuel is. She pays, comes back, I get my snack and off we go.
I go riding with a friend, we pair the BT headsets. I'm leading, I tell him where I'm going, what to look out for, toilet breaks and refuel stops and general chit chat. Fantastic and no PTT, all VOX.
