With me comfort is king. I have a really hard time getting any type of headphones to stay in my ears so was excited to try this different style. Theres really only one position that will fit a full-size road bike. You cannot put it on. Pretty expensive for product though but it?s ok I guess Have installed over 5 and all of them have failed. Nice colour and as ever with Birkies very comfortable. I am not a iPhone person. I like this bra and it?s versatility for the price-point, and I bought it at around $15. Your feet will NEVER ache again.
