I bought a pair of Shure Se-215's today secondhand, and I noticed that they aren't recommended as much as they used to be. What happened to them, are they still good compared to others in their price range? I got mine used for 45 bucks with the case and the ear tips, I couldn't find anything...

I performed the Foam mod on my HD558s that I recently bought, and I loved them afterwards. I was wondering if there were any other modifications for the HD558s, I wasn't able to find any with a google search.

I actually just found some in a good condition with the carrying case for 30 bucks, im pulling the trigger on that

I have 35 bucks, I could stretch it to 50 if they're really good I'm looking at some of the following VE Monks IEM Shure SE 112 Used Hifiman re400 waterline Used Sennheiser hd558 Used Phillips SHP9500 KZ ZST Does anyone have anything to say about these or other IEMs or Headphones that might...
