Trying to sell a DIY closed back headphone a friend made using the hifiman or Sony R10 cup. Since sound is subjective I won't get to the detail or comparisons of it. I can say it's more towards the bassy side, pretty analytical, weird soundstage because it's a closed back dynamic driver headphone. There's a little chip on the bottom of the cup but won't affect the sound too much. Most DIY using this mold on "闲鱼" or "goofish" are asking around $280usd without shipping. My parts are a little more around 350ish since I was able to chose the driver.

Parts used includes:

• Of course the R10 cup
• Perforated earpads
• Driver: Oem factory not exactly produced by Fostex, 50mm either 32ohms or 40ohms
• Hifiman headbands

Asking for $250 obo includes shipping.
