I will admit I do have some regrets. In one way, I got to hear details that I hadn't heard in really cheap buds and speakers. And I did learn quite a bit of things about audio over the past few years. In another way, I became more focused on finding the "perfect sound" rather than listening to the actual music. I tried a few IEMs and headphones, only to be disappointed. Nowadays, I wouldn't feel as happy spending more money on high-end equipment and thinking about what "pairs" with what. I have been much happier just listening to my HD600's and even cheap stuff without thinking much about its flaws.

I have a pair of JBL 305P MkIIs for my desktop setup, and they have pretty much stopped my search and interest for headphones. Other than needing a subwoofer for deeper bass, they sound just as good as my HD600's IMHO.

Sounds like I made the right call then lol. I haven't heard the 650, and don't have any plans to, but I have heard the Rode NTH-100, which did sound overdampened and blunted.

Midrange and timbre are very important to me, which is why I pretty much enjoy the 600's sound more than other headphones I've tried. But I do listen to my K701's from time to time for something unique.

Definitely not ideal, at least for me. Why does it show such a huge subbass boost?
