I saw a CL post that is selling a 6 month old Sennheiser HD 650 for $260. This seems a bit too good to be true, but I have lots of time on my hands so I plan on meeting with the seller to check it out.
Is there anything particular I should look for when buying a used HD 650?
I will be bringing my laptop and a Fiio E10 to audition the headphones.
Are there any notable scams involving these headphones? Can people swap out components in the HD 650 for cheaper components?
