I have owned the HD 660S for three years. I used to have a K371 for a year but "upgraded" to the Noire due to comfort reasons, which I have now owned for a bit over a year.

I used to be an in ear guy. My daily driver were the shitty ones that came with the MP3 players I used to own. Then, I found the Sony MH750 and stuck with that for five years. Recently they died on me, so I tried the Truthear Hola, which has pleasently surpised me.

The only purchase I am currently considering is some proper speakers. I am talking Genelec 8030Cs and a sub here.

I have tried countless headphones and none of them truly left a lasting impression on me, other than HD 800. Sadly I find it very uncomfortable to wear, so I do not plan on buying one.

I think a lot of the buying hype is fueled by FOMO and NTS. People seem to always be chasing a new high, as they say. Nothing wrong with that approach, don't get me wrong, it just ain't my cup of tea.
