Has anybody had any experience with these? Seeing as qpad teamed up with beyerdynamic, this makes it a very interesting headphone, but I couldn't find any decent reviews for them

right, so I found out that these are a rebrand of beyer mmx300.
 
and then i was told that mmx300 = dt770 + mic
is this true? If it is, it kind of makes them not worth it, considering that they cost twice as much as dt770 :S
 
can somebody shed some light on this please.
 
also, apparently they come with

- Other: Including USB soundcard

yep, the beyerdynamic MMX300 / Qpad QH-1339 is a DT770 32 ohm + boom mic.

Maybe the same driver, but it's differently tuned than the 770, so the sound isn't identical. The price is stiff because they include a high quality mic worth 150 euros.

Zreviews on YouTube reviews the MMX300 1st gen, the same as these, have a look, it's quite interesting.
