Can you try to rephrase your questions?
I got a bit lost in those posts.................sorry!
I own the DT990 Pro 250-Ohm and the T70 (250-Ohm), in general the T70 is better over all, the T70's clarity is a step up from the DT990.
But as a new Beyer T70 cost three 3X the price of the DT990 Pro 250-Ohm and 2X the price of the DT990 Premium 600-Ohm.
I can see a lot of people thinking the T70 is not worth twice the price of the DT990 Premium 600-Ohm.
The T70 has about 1/2 the bass that the DT990/600Ohm has. As far as soundstage the T70 sounds more closed in with less air, but the imaging is much better IMO.
I find the clamping force just fine with my DT770 Pro 250-Ohm.
Thanks; seems good. How about the ear cups? Plenty of room inside? I read that the 80 ohm were roomy, but haven't found much about the 250 ohm.
Yes, you can stretch/bend the headband. I do not think it is different between the 80 Ω and 250 Ω versions (there is a single part number for all DTxx0 series "pro" headbands), although it may have some random manufacturing variation.
The ear pads (EDT 770 V) are identical, and should be equally as deep at the same clamping force. The DT880 and 990 have a different and softer type of ear pad, which is slightly less deep when worn.
DT-770 Pro LE , At Home .
There is nothing on the Box , a card with technical data , and some stuff printed on the box to the glory of Beyerdynamique . Well there is the headphone soo
I think that it use the same old 32 ohms drivers used on "amen" DT-770 Edition , because what i am hearing is very close to what Zombie_X says about DT-770 32 ohms , they sound decent from a Galaxy S 3.6 player , but the addition of an Amp helps , on Auditor it's noticeably better (well it's Auditor ) .
Nothing more to add now , just get them only 35 min playing , but kick drums are greats on it .
