The value of your headphones are fantastic. I thought they sounded much more expensive than they are. My only complaint is with the cable. But I understand if that is a cost issue. While the looks are very nice, I think the carbon fiber would be awesome. Really like the headband pad. They have a little more clamp than I like. But overall a very nice entry in the headphone market. I posted some comparisons on the loaner thread. The biggest difference compared to TOTL phones is the speed. Also the control during large dynamic swings. But overall I think you designed a real winner. Congratulations. I would love to see some pics of your assembly process. You said you are building them in your kitchen? If that's so, I like what your cooking!
