Was going to return and when I went on line to return I was 2 days past the return date, so unfortunately I am stuck with them and will probably just donate. If its an iPhone or Android that you use, download a music player app that has an Equalizer. Filter is pretty standard, but Im glad it came with it. They stay in my ears just fine. Will be returning these huge shoes. Great material and really well made even the noise canceling is better. I have bad knees, and walking usually bothers me. It is sturdy and was easy to install. Also, they are more comfortable for those who work every day standing and moving around on the job. Not the best when moving heavy gear around the shop.
