Don?t waste your money! I have a road bike so Im not sure but there is plenty of room for a wider tire bike. They fit so comfortably. These are actually perfect for podcasts and video where big low end isnt as important. 5 hours)- despite the lights on the case saying theyre fully charged, theyll unexpectedly turn off within the first few minutes of the 3rd use- placement of "pause" & "play" buttons on the ear pieces are frustrating. It comes with 3 size of ear pieces and a small cord to attach so that they are not lost if the fall while running, etc. ) I dont recommend these at all. This is a life saver when it comes to the outlets. They are moving to my feet. The memory foam is garbage.
