I just have two days with my new Bose SoundSport Free earbuds and I'm having some headaches and get easyly distracted, I'm concern about it because I bought this earbuds to listen music while I'm working( long period of time).
Thanks for your post and welcome to the community. I am sorry to hear that you are having these issues.
Have you attempted to use the different sizes of Stayhear tips, this may have caused you to have discomfort? If the headaches continue I would recommend that you reach out to your doctor to see what the reason of your headaches is.
