Sound quality is just truly fantastic.
I do build my own headphone amplifiers for many years and do own more that few various headphones to spoil myself.
I have to say that these are my favorite to the date.
Believe me, that even my HD800 are not used that often as these here,they K701 are just fantastic.
One thing need to be said though, you do have to drive these properly, without enough juice you will not hear its full potential, but just providing enough current and these do sound phenomenal, its a class for itself.
These are no new to the market, and have proved to be trusted choice for many. Providing you can give them what they need, and you will love them.
The bottom end of the spectrum is where these can show their true capabilities when you can feed them with enough power. Highs, and middle are just majestic, and every type of music and recording sounds just natural and organic. Can't fail them for anything.
I also believe that they are fantastic value, to the date these are best you can buy, not spending crazy money for the pair of headphones. I own/ed many far more expensive headphones, and some of them are not even close to these, where it comes to the sound quality and tonal balance. You will not be disappointed with these, they are just worth the listen.
I have also K7xx (limited edition) but 701 are far more natural and organic for me and my accompanied headphone amplifier.
Give them a try and have fun, out there.
Uncomfortable for baldies, sound great
These headphones sound excellent when driven by a good amp and look quite stylish in a retro kind of way. They are only 62 ohm impedance but have a low sensitivity of 93dB/mW so whilst not needing a very high voltage they need plenty of current. A decent solid state amp with low output impedance is ideal (I use the open source O2 from Epiphany Acoustics) - a tube amp with high output impedance could interact with the low impedance of these headphones and cause anomalies.
The only criticism I have concerns the headband as many have commented on before. The underside has eight hard bumps which start to dig into my bald head after a while and become uncomfortable. I corrected this by sticking some light foam over the central few bumps which contact the head and they are fine now. Comfort rating is 2 stars vanilla and 5 stars after my low tech mod. Non baldies probably won't notice anyway.
The sound signature is very different from my Sennheiser HD650 - the K701 is much "clearer" to me. They have a reputation for being bass shy but if properly driven (see above) there is plenty of deep bass when needed. Both headphones sound great, just very different. I like the K701 particularly with smooth jazz, acoustic guitars and vocals. They are also good for games as the transients have great "punch" for gunfire and explosions. Sonically the K701 is the same as the K702 and Q701 just different aesthetically and with a fixed cable.
Hope this helps
AKG K701 White
Powerful amp required to make these come alive. No EQ / colouration - Pure flat-line reference phones ; what you hear is what's on the CD / music.
Very capable of giving high impact bass, sub-bass, and treble. Mids and vocals are excellent too. Separation of instruments is amazing, you can sense the space between the different instruments / sounds.
Due to no colouration they may seem dull compared to other non-reference, more coloured phones as these are reference in the truest sense of the word.
Due to their precision and lack of colouration other genres may sound more clinical, harder to enjoy, I put this down to the mastering process of music simply mismatched for these headphones. Suits ALL genres provided they are well produced, with jazz, classical and vocals it is supreme.
Music has a crystalline sparkling clearness and power that engages and enthralls, and is the closest headphone I have ever heard that makes me feel actually there with the artist/s. Just for perspective I have tried the Sennheiser HD800's and they are given a run for their money by the K701's. Considerably less expensive at about ? of the Sennheisers.
I have trouble finding an adjective to sum them up, the closest I can get to a description is spacious, crisp, punchy, phenomenally articulate / lively and an absolute pleasure to listen to.
I think they are from an advanced alien civilization, absolutely awesome!
Broke down just after guarantee time
Alas, they broke down again, now there is no sound in left speaker. And it happened two month after the guarantee time was over. Period. Not very pleased with the product or Thomann's way to dead with the issue. I'm the person who they can call "ex-customer".
