This auction is for the oldest headphones I own. These akg k702’s are one of the first made out of the k702’s. I think I bought these from sweet water new about 10 years ago for about 400$. They still work great but the Ear pads are worn but can easily be replaced.
After buying and returning three other models of headphone, these finally did exactly what I wanted them to do: provide accurate sound with a lot of detail while being COMFORTABLE enough to wear for a long time. I'm using them primarily for mixing and production, so accuracy and comfort were my biggest priorities. If portability is above these things on your list of priorities, I would not recommend these. They have an odd shape and seem a bit delicate to me, so I wouldn't really feel comfortable taking them out of the studio, though I might with a proper carrying case.
I tried the Beyerdynamic Custom Studio and Audio Technica M50x headphones but returned them both because they were extremely uncomfortable for me (other people have no problem with them and even find them notably comfortable, but I had a lot of trouble with the pressure they apply against the side of the head - I guess it depends on the person). These ones are very light on the ears, which for me was super important. This likely has to do with them being open-backed, so they don't need to create a seal around the ear to the same degree (the open back also means sound bleeding - not ideal for listening on busses or monitoring with when recording vocals). They felt a little bit weird at first, but after several weeks I can attest that they are comfortable enough to wear for long periods of time - I have not once had to take a break from my music because of headphone pain, unlike with the other models I mentioned.
Another thing I love about them is their accurate sound response. The M50x were very bassy (some may argue with this assessment, and people who are using them for casual listening may even want something with a hyped-up bass, but for my music production, accuracy is key). Music sounds like I'd expect it to, but with more detail (and perhaps a wider sound stage). If your headphones sound completely unique and unlike any device you normally would listen to music on, they may not be ideal for mixing on. That is what I encountered with the somewhat obscure Yamaha MT220 headphones I tried.
The process of finding a good pair of headphones (for mixing and perhaps also for other purposes) may be a long process of trial and error for you as it was for me, but my search came to a very satisfying conclusion with these headphones. Two thumbs up!
These are my first set of open headphones and I love them. I have the Shure SE530's and the Audio Techinica MTH50X's and these blow both of them out of the water and they haven't even been burned in yet!
It does need a bit more power to operate so I bought a Fiio E12 amp to complement my Fiio X3 and the sound is simply incredible. The soundstage is massive and the instruments are crisp. These are very lightweight and solid. AKG has won a customer for life.
