I used these headphones in my small guitar studio for a very short time. Headphones are a useful tool for guitarists when trying to learn solos by ear. These headphones are useless for this particular application. They are mushy with little definition and they clip easily,  even when pulling out the lower frequencies and operating at a reasonable volume. I ended up giving them to my 18 year old daughter hoping that she would have better luck than I. Eventually I ended up going with the Audio-Technica ATH-M40x and I couldn't be happier.
