If you are looking for something that gets the job done for half the price or less of the two or three dominators of the intercom world, these will work out well for you.
I purchased this to use as a solo rider, the sound quality of music and GPS are great. I don't answer my phone or communicate with others so I can't rate that
I would recommend these to anyone looking for an affordable communication system.
Switching over from music to communication is very easy, it does take a few seconds (about 5-8) to connect if you are listening to music to switch over communication but that is a a minor "inconvenience" considering how good the system works. We rode for hours and had the headsets connected the entire time and the battery barely moved.
This system works great for solo riders that are just looking for music as quality is clear. Perfect for an entry level headset.
