I have had them 2 weeks and the only issue I have is with the volume you can’t turn them up on a phone call

Thanks for your review. We are sorry to hear about the volume issue you have encountered with your Bose Ultra Open earbuds. Increase the volume by pressing the button on the right earbud twice and continue to hold the second press. The volume increases as you hold the button. Release the button when you reach the desired volume level. Decrease the volume by pressing the button on the left earbud twice and continue to hold the second press here: https://www.boseapac.com/en_in/support/articles/HC1027/productCodes/ULT-HEADPHONEOPN/article.html#:~:text=Increase%20the%20volume%20by%20pressing,to%20hold%20the%20second%20press.

These are the most comfortable ear buds I've ever had! Sometimes I forget I'm wearing. The battery lasts my entire day at work too. 10/10, would purchase again!
