These are the BT S3 bluetooth headset units. I bought these last fall and used for one road trip. They are in excellent condition and work as advertised however sound quality is lacking at high speeds. You will need to replace some velcro and or double sided tape that I used for installation.

50.00 shipped for both

 

New price 45.00 shipped for both

 

New price 40.00

 

Can these be used as intercom between two riders or more? If so, I'll take 'em!

 

The manual states bike to bike intercom with a range of 800 to 1000 meters. I assume they work for two riders. You can find them on eBay and Amazon you may get more info there. They are called bt-s3 Bluetooth intercom. They are low cost units so I wouldn't think you would have the ability for multiple connection

 

I used them for rider to passenger intercom so I know you can have two connected

 

That's what I wanted to be sure of, so wife and I can chat while riding, either together or each on our own bike. PM sent.
