The AKG K701 are comfortable and breathable critical listening headphones with a great sound quality. Unfortunately, they do not have a detachable or spare cable like the K702 or the K712 Pro. They're also not meant for outdoor use so they have poor isolation and no control options for mobile devices. On the upside, they're surprisingly lightweight for their size and they deliver in the sound department.
- Excellent audio reproduction.
- Comfortable design.
- Very sensitive to ambient noise.
- Open-back design leaks a lot.
- Big and bulky headphones.

The AKG K701 are comfortable, but bulky headphones not meant for outdoor use. The large circular ear cups are well padded and soft, and headband strap auto adjusts to different head shapes and sizes. They're durable enough, to handle a few drops without breaking. However, the headband has many moving parts, which may wear and tear over time. They're also a bit too cumbersome and unstable to use casually and definitely not for sports.
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.
The AKG K701 is a very good sounding pair of open-back over-ear headphones. They have a decent and consistent bass, an excellent mid-range and an above-average treble. However, their bass lacks in thump and punch, their mid-range is a bit forward, and their treble is on the bright and sibilant side. Additionally, they do have an open soundstage and image well.
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.
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.
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.
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.
Decent harmonic distortion performance. The amount of harmonic distortion in the bass and mid ranges are rather elevated but within good limits. The couple of peaks at 1KHz and 2KHz could make those regions slightly harsh sounding though.
The AKG K701, like the K702 and K712 PRO, are not headphones to use outdoors or while commuting. They barely block ambient noise and won't fair well in loud environments. They also intentionally leak to provide a bigger soundstage, which will be distracting to anyone around you, even at low volumes. These headphones are best enjoyed in private and in a quiet room where ambient noise cannot seep into your audio.
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.
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.
The AKG K701 doesn't have a microphone.
