I tested the headphones by fitting them into closed helmets. Even when I was standing in an absolutely quiet room, I could hardly hear the conversation on either side. They will NEVER work between riders at any speed. I tested this again with a Midland radio on one end and a helmet mounted headset on the other end. The radio picked up the conversation perfectly from the helmet headset. So the problem isn't with the microphone, it's with the speakers. If you can figure out a way to connect the speakers to the headphones, they "might" work, but my electronics buddy tried it, and the wiring is so small it would require special skills. I am very disappointed in this product! Too bad Midland couldn't build a better working rig. money wasted.
