I find it ridiculous that many humans here feel the need to "mod" their phones, especially this one. Do you buy, say a pair of $10k B&W loudspeakers and immediately crack them open and begin to replace, hack, cut etc, thinking all along that you know more than the team of engineers who labored intensively over the design for years using the most sophisticated computers, software and manufacturing techniques available to a multi-million dollar company in an attempt to improve the sound? Maybe modding a cheap pair of phones is one thing but certainly not the DT1770s. I own them and find them to be exemplary performers, especially at their price point. If their sonic signature is not what you wanted, then maybe you should have done more research. Oh and BTW, you just null and voided any manufacturer warranties and decreased your chances of resale once the potential buyer learns you hacked them up.
