Thre is actually a bit of truth to what the original poster said about the Titanium Rs headphones.
Once upon a time...Radio Shack sold the Pro-35 headphones...these were Koss KTX Pro rebadged phones.
Now having owned (still owned) tons of phones, some with decent reputations, including the classic Sony V6, the Grado Sr-60's, the E2c's....Koss Porta Pro's.......I can honestly say that the Pro-35's are the most amazing phones I have ever listen to. The bass extension is phenomenal...unmatched by any phone I have ever listen to. Absolutely clean midrange....zero siblance...complete lack of shrillness in the highs. Amazing.
I loved them so much...that when Radio Shack closed them out...I bout 6 boxes of them. I use them to this day...and will continue into the near future. Do a search on Google...you will find tons of raves about these cans.
Now...UNFORTUNATELY Radio Shack replaced them with the
Pro 35A. Yikes....nothing like the 35's. I find these to be shrill without the bass extension. The Koss Porta Pro's also lack the old 35's dynamic range and bass depth.
Sooooo the 35's will be in use until all my pairs fall apart. Since I never leave the house with them I figure I should have them for the rest of my life. I will now and then listen to the Grado's...but I find I miss the bass of the 35's.
Morale of the story...if you find cans you like...but two pairs
