Ditto -- these new T1s (46xx) have great, robust bass. I was originally planning to hang onto my DT990/600 as my fun, bassy headphone -- not anymore! The bass on this new pair of T1s is nearly as strong as that on the DT990s, as well as being tighter and more articulate. Great stuff!
More fuel to the fire -- here's a ranking of bass quantity in the various Beyers I've had over the past year:
DT990/600 > T1 (46xx) >> DT880/600 > T1 (19xx)
The two T1s I had really were that different.
The 35XX I had did not have anywhere near the bass quantity of either of my DT990s. More than the DT880 for sure, but not even close to the 990. The T1 was basically bass neutral. If I got one with just like 10% more bass, I'd be in heaven.
If Beyer has come out and said there has been no change, what are we to make of all this? Lies? Bad quality control? Different head positioning?
