Been a long time since I have posted here but was wondering what everyone's thoughts on these two units would be? Pro's, con's to both etc. I have always just used earbuds for music and never used any comms when on my bike. I am planning on doing a few group rides this summer so I was wondering what everyone else is using. I have heard the Cardo Slim is the way to go as the price is the same give or take $10. I am leaning towards the Cardo just wanted peoples input.
