I have been using my iphone earbuds which are very comfortable for gym and day to day use, not very good for the racecar. Too much noise interfering with my ability to hear the tower.
I have some hearing damage from my military service which I am sure is a contributing factor.
Some guys I have talked to say they run basic JVC buds they picked up for cheap. Others have $100+ ones from Racing Electronics.
Ideally I think the foam ones from RE are probably best but more then I want to spend. Is there a cheaper brand that sells a similar product?
