성향이 다릅니다.
598보다 고음이 좀더 쎄서 여보컬 특화에요
전 598에서 k702로 갈아탔습니다

K702에 기반을 두었는데 완전히 동일하지는 않고 차이가 있습니다.
디자인은 K702 65주년 기념판을 기반으로 했습니다. 색상이 다소 다르고, 패드는 일반 702가 아닌 65주년 버전으로 더 좋습니다.
소리는 매스드랍 트위킹이 들어갔다고 합니다. 즉 매스드랍 버전이 더 V자 라고 하네요.

"Massdrop’s AKG K7XX are made in China as most of the standard version ones you buy from amazon today. Massdrop edition is tweaked particularly in its sound signature and design wise is based on 65th edition of these headphones. The sound reproduction changes were done purely on a Massdrop’s request. But let’s go back the the design first. As you can see from the pictures Massdrop’s version is completely black. Even the stitching on the headband is black. On the standard version is blue. Than on the standard version some parts of the headphones are silver which might evoke a bit cheaper look. But again it’s a matter of an opinion. And then there is finally one significant difference. Pads. The pads are quite different in comparison as on the Massdrop version those are based on the 65th edition which are more comfortable, slightly thicker and have a memory foam effect which the standard version don’t have. It doesn’t mean the standard version of these headphones is not comfortable though."

Differences in sound comparison with Massdrops version:

"Even without reading where the changes have been made and requested they were very obvious to me even from a first listening and I personally don’t like them. I would not choose Massdrop’s version as they felt to me more V shaped which is just not my cup of tea and it is like trying to make them from a commercial point of view ( so they sell) for everyone or for the most / masses in a way of changing what these headphones are. I don’t want to be too much critical in this but this is not about tweaking something good to be even better from my opinion. Massdrops version has slightly more bass and even another elevation of highs which cover the mid section quite a bit so they change in that way theirs personality to me. I prefer the neutrality, slight elevation in mids and highs of the standard version. But that is my personal taste and opinion. It might differ to you."

네이버랑 가격차이 많이 나는것 같네요

블랙은 괜찮은데 레드는 별로네요

색상은 개취입니다.
