I got both the regular and the wide versions. Using them on my DITA The Answers, I find I prefer the recommended wide ones in medium. In Complys I always use the large, but these are harder and don't compress down like the Compys so I find the mediums are a better fit. Good bass, possibly better than the Complys, and a bit brighter sound overall. I like it. So far, I find that they shift more in the ears so the sound quality shifts as well, so for active sessions at the gym they tend to go in and out for ideal sound. Not sure if that will reduce as my ears get used to them. But I am happy with them. The regular size ones pump up the mid bass a lot compared to the recommended wide ones, and it's too much, it also does something odd to the soundstaging. Also, they are the best sound isolating tips I have ever used, they block noise very well.
