I have been having troubles dealing with EQ, one of the problems being my hearing. However, there appears to be another oddity causing great frustration... A variability of headphone frequency response... This variability is making me consider the gray or counterfeit market. ( I apologize for my wordiness -- regularly criticized for that.)
This variability is on 2 'alleged' Beyerdynamic DT770/Pro80 -- exactly the same model. The only obvious outside difference is in the cable, where one cable is slightly more stiff than the other.
I also have a DT990/250, which I have grown to like much better than either DT770 anyway. One of the DT770/Pro80 that seems to be at variance on freq response, but inconsistently has the cable most similar the good DT990 (special model) headphone.
There are a pair of inconsistencies... The DT990 with very flexible cable and the DT770/Pro80 with the stiff cable have the most clean, wide range sound. While the DT770/Pro80 with the seemingly high quality cable sounds like a 'telephone' in comparison.
Is QC is amazingly bad or are there are a LOT of 'really deceptive' gray market goods being sold? With my poor hearing, and difficult to compare references, I was clueless about the odd, telephone-like headphones but also unfortunately very dependent on the quality. First DT770 (sounds good/correct), second DT770 (sounds like a telephone), DT990 (sounds clean, good, correct.) I physically wore out the first DT770 because of nearly continual use for several years. Otherwise, there was no motivation to replace the first DT770.
The headphones that sound most similar (and really clean/good) were purchased from a very well known equipment seller (DT990) AND an Amazon outlet (first DT770). The questionable headphones (second DT770) were also purchased from the same well known, and very much trusted (by me) equipment seller.
Gray market, bad QC or early failure? I haven't contacted the seller yet (several months after the purchase of the tie-breaking DT990) because of being crazy busy, but I will be making a contact soon mostly to warn them.
Any for the ideas on this matter? Thanks in advance...
(BTW -- no matter what, even liking closed back, I VERY MUCH prefer the open DT990/250.)
