Sennheiser HD 600 Impressions Thread

Are you talking about the pinna gain peak at 3.5k? Because neither my set nor any others I've seen have a measured 4-5k peak.
Here's the OG marble HD600 vs the modded one. As you can see, the 5K resonance is quite subdued.

Huh. Looks like you might have an outlier set. Most (measured) sets seem to peak somewhere between 3.2k and 3.8k, and it isn't a resonance peak. AFAIK the only major resonance on the HD 600 is somewhere around 100Hz.

I tried the 620s today and was severely disappointed. The bass was weak, and felt like it lacked dynamics, and overall felt more boxed in than the HD600. The isolation also felt pretty minimal for a closed back.

I would safely say that the HD600, paired with a good bass boost or EQ feature does the job much better than the 620s

Sounds like you didn't get a good seal, as this is the opposite of most feedback so far.
