A:
I had a pair of old Sennheiser HD 202's that cost 40-50$ at the time, and I owned for years. I loved those headphones, but these are everything they were and more. The build of these 558's is way more solid. They sounds better in every range with a huge sound space, but keep in mind the 558's are open back unlike the 202's so bass especially sounds different (better though). They feel just about as light, however being open back they stay cooler, and the velour padding is more impressive/comfortable than I imagined. HD 202's had a long cable, and the 558's have a thicker cable at the same length with a twist lock mechanism (so I don't feel as bad when I step on it). All around better headphones than the 202's.
