In another topic where the poster started out asking whether to buy HD 650s to go with his Total Bithead, Boomana said: "If you're looking to be happy with what you already have (the Bithead), I actually recommend different headphones. I recently purchased the ATH-ESW9s. The aren't as refined as the 650s, but may actually sound better than the 650s when using a Bithead. I'm very happy with this purchase, and (new toy syndrome) haven't touched my other headphones for a few days. They also have the advantage of being closed and portable (best of both). You can use the Bithead with your computer, or take them out with you. The sq is really very good, and they are seriously comfortable right out of the box. I've bought a few new headphones I instantly didn't like. These are keepers. If you primarily listen to a lot of hard rock or metal, I would not recommend these, but for acoustic, jazz, chamber, pop, etc., they're wonderful, and the Bithead can drive them with no problem. They'll also wipe out your entire $300"
