I currently have some OVC TC-20's but find that when I am getting my helmet on it knocks them out of my canals and I lose the seal, the best I can get is having them kinda sit near the canal, it doesn't sound good.
I use the headphones all the time and can get them to seal, if i'm say laying in bed or on the bus etc but pulling the helmet on dislodges them. I am already using the smallest tips that came with the headphones, the bigger sizes don't fit as well in my ears....
Perhaps i have small ear canals?
I need a replacement set of headphones, I have up to $300 to spend.
I didn't find the right solution from the internet.
