I want to upgrade my headphones to either the m50s or 558. Right now i have the sennheiser 428. I was wondering if anyone has had experience with that headphone and they have upgradede to the 558. The 428s are somewhat flat sounding, but honestly i dont want to get a pair of headphones that are more flat responding which i've heard the 558s are. Which is also the reason why im considering the m50s.
Can you help me here? Im on my phone right now, so i may need to clarify.
