Buying a used model is a luck game especially with the “open box” label unless it’s officially labeled as “factory refurbished” or “factory reconditioned” as Sennheiser normally label and such products.I had bought open box Aryas last summer, and the upper midrange timbre was way off.. I hadn't bought another open box since, though there have been some pretty good deals. I still don't know if all of that model sounded like that, or if I had been resold a dud.
When you buy them used or pre-owned meaning someone upgraded and that’s a better chance to have a fully functional cans, companies either sell brand new items or in this case fixed returned malfunctioning or demo items.
A half priced or partially priced item is never worse more than it’s used price, there’s no magic there IMHO
