K702- reference headphones (same like K701 + removable cable) , you realy need good amp for full performace
K271 MKII- studio headphones (no reference sound i think just a regular mid range headphones )
this is kind of misleading. studio headphones are used to reference recordings. reference is kind of ambiguous

sorry to disappoint you, AKG K271 require almost just as much amping as a K701. I have owned the K271 and I currently own the K701. I have under-amped both with the same Ibasso D10 and the K701 seems like it requires less power. I could be recalling incorrectly but K271s do need a lot of amp power. I sold them for that very reason. However, I am fine with the K701 with my Ibasso D10. i had the Grado SR125 and SR325 before and the sound are very similar to each other. I thought the sr225 sounded too much like the 225 to be worth the extra cost. ALSO, i sold all my Grados btw. I prefer the sound of AKGs far more than Grados. I found the Grados to be ridiculously unnatural. The highest highs were incredibly exaggerated to me and the bass randomly spikes in different areas of the low range.
I recommend the ES7. They are great portable headphones and sound really good to me. I love the bright and punchy sound they have. I also recommend the Sennheiser HD280, though they are ugly
