Based on some positive comments here, I purchased the Bose QC20 earbuds. Within minutes of the first use, and two more after, I feel motion sickness. Strike one. I tried fitting my Arai FF with the earbuds in, and the helmet pulls them out because they stick out too far. Strike two. Returning these to BB where I purchased them. On a side note, they did seem to eliminate some noises, like a vacuum cleaner, but not 100%.
