I will say this – if you try them out and don’t like the fit or think the sound just isn’t precise enough…change the tips for a smaller size. That happened to me. I simply tried them out with the tips that came with them on it and was sad because they wouldn’t stay in and the sound seemed mediocre. After double checking the box, I found the little zip lock package with the extra tips in them and quickly changed them out so the smallest size was on the headphones. WOW! What a difference. The smaller tips allowed the headphones to go further into my ear and the sound became high quality with great bass and clear treble. I can actually shake my head and the headphones stay in. I love them!
