I ordered the 2050's from this guy on aliexpress it was on sale. They've shipped and I'll write a review once they get here. Unfortunately head-fi removed alex-roma's review.
Takstar HI 2050 performance change pretty evident during burn_in !
Out of the box we have a baby DT990 , after 150 hours however, Takstar lose that ala DT990 bass, acting more like a baby DT880 (32ohm version).
I've ended up using some extra damping to reduce_treble/increase_bass, after that, DT880pro balance has been finally achieved.
So yes, these headphones look and feel so much like the DT880 indeed. But you wouldn't get Premium DT880 600ohm performance out of HI 2050, no matter what mod you try, 600ohm bayers remain unbeatable reference.
So, I find Takstar HI 2050 a perfect gaming/youtube headphone, with better then average ~150$ product package, built, comfort, performance, neutrality, extension, sensitivity and price .
Nowadays it's almost impossible to achieve all those goals under 100$ price tag. Sennheiser HD558 are no match in my opinion.
Verdict : Giant Killer
