I have seen few pictures of AKG K81DJ headphones and Panasonic RP-HTX7 monitor headphones while surfing internet and would like to get some more information on them. Which among the both is better performer. So if someone has any information about them and the manufacture's specification or someone who had already used them, please share your knowledge with me also. It will be very helpful of you guys to do so. Suggestions will be appreciated. Thanks in advance.
