The AKG K701 look almost identical to the K702 and K712 PRO. They have the same retro design with large circular ear cups and a headband with a self-adjusting strap. The open-back ear cups are well padded and covered in a suede-like fabric that gives the headphones a more premium appeal. However, like the other models in this series, they're bulky and little too big, to casually wear outside.

The K701 are very comfortable headphones. They're surprisingly lightweight for their size and the well-padded ear cups fit well around most ears. They don't cause any fatigue during extended listening sessions.

These headphones like the K702 and the K712 Pro are big, bulky not really portable. The retro headband makes them quite large and since they don't fold into a more compact format, they will be too cumbersome to carry around on your person if you do not have a bag. They also don't come with a case or pouch, which is slightly disappointing.

The build quality of the AkG K701 is decent but has a lot of moving parts. They have dense ear cups, and the headband design is flexible enough to handle an above-average amount of physical stress. Unfortunately, the headband has a lot of moving parts for the adjustable padding. These are potential weak points where the headphones could get damaged by wear and tear.
These headphones are not designed for sports or intended for outdoor use. The ear cups will sway and slip off your ears during physical activity, and the non-detachable cable will yank the headphones off your head if it's hooked on something.

Sound
Bass Amount -4.76 dB
Treble Amount 1.18 dB
Avg. Std. Deviation 0.38 dB
Great frequency response consistency. Like most other open-back headphones, the AKG K701 has very good consistency in delivering its bass. The maximum deviation we recorded was 3dB at 20Hz, on only one of our human subjects. The treble range consistency is also great with the K701, however, at higher frequencies they are prone to larger deviations because of their large ear cups.
Std. Err. 4.04 dB
Low-Frequency Extension 92.43 Hz
Low-Bass -7.49 dB
Mid-Bass -3.5 dB
High-Bass 0.18 dB
Decent bass range performance. LFE is at 79Hz, which is below average. Low-bass, which is responsible for low-end thump and rumble, is lacking by more than 5dB. Mid-bass, which is responsible for kick and punch, is also lacking by more than 2dB, resulting in an overall bass that is lacking a little in thump and punch.
Std. Err. 1.37 dB
Low-Mid 0.02 dB
Mid-Mid -1.67 dB
High-Mid 0.95 dB
Excellent mid-range performance. Low-mid and mid-mid are nearly flawless and within 1dB of our target. High-mid shows a bit of boost around 2KHz, making the overall sound of these headphones a bit forward.
Std. Err. 4.07 dB
Low-Treble 2.1 dB
Mid-Treble 4.26 dB
High-Treble -4.1 dB
Above-average treble range performance. Low-treble is overemphasized by about 3dB, adding a bit of excess brightness and detail to vocals/leads. They also show more than 4dB of overemphasis in mid-treble, increasing the presence and sibilance of vocals and lead instruments.

Isolation
Overall Attenuation -3.81 dB
Noise Cancelling No
Bass -0.04 dB
Mid 0.31 dB
Treble -11.46 dB
Poor isolation. Due to the open-back design, the AKG K701 doesn't isolate below 1KHz. Above that, they achieve about 12dB of isolation, which is sub-par.
Overall Leakage @ 1ft 61.64 dB
Poor leakage performance. The significant portion of the leakage is spread from 200Hz to 20KHz which is quite a broad range. The overall level of the leakage is also quite loud, making the leakage of the K701 audible to those around you.
Are AKG Pro Audio K701 any good?
Incredible sound! I really enjoy working with 701 headphones. They are very comfortable allowing me to work for long hours without fatigue. Very accurate sonically. Great value for $.
