The AKG K701 deliver a great audio reproduction that's balanced, open and immersive. They're comfortable and not too heavy for their size, but they're still a bit too bulky and cumbersome to use casually. Also, their open design makes them practically unusable outdoors.
- Excellent audio reproduction.
- Comfortable design.
- Very sensitive to ambient noise.
- Open-back design leaks a lot.
- Big and bulky headphones.
The AKG K701 provide a comfortable listening experience, but a bulky design that's not versatile enough for all situations. The large circular ear cups are well padded, soft and suitable for long listening sessions. They're also sufficiently durable, to handle a few drops without breaking. However, the headband has many moving parts, which are potential weak points. They're also too cumbersome and unstable to use casually or outdoors and definitely not for sports.
The AKG K701 look almost identical to the K702 and K712 PRO. They have the same old-school, retro design but in a two-tone white and gray color scheme. The open-back ear cups are large, circular and covered in a suede-like padding that gives the headphones a premium appeal. However, like the other models in this series, they're bulky and little too big, to casually wear outside.
The K701 are just as comfortable as the K702 and the K712 pro. They're incredibly well-padded and do not feel too tight on your head. The large, circular ear cups easily fit most listeners and do not cause any soreness or fatigue even during extend listening sessions. However, they can feel a bit massive for listeners with smaller heads, but they're relatively lightweight for their size.
These headphones are not designed for sports or intended for outdoor use. They're not sufficiently tight, to stay in place, if used while doing any physical activity. The ear cups will sway and slip off your ears, and the non-detachable cable will yank the headphones off your head if it's hooked on something.
The AKG K701 are big and bulky headphones that are not portable. The retro headband makes them quite large and results in a headphone that's cumbersome to carry around, and will only fit in a backpack. They don't fold up into a more compact format, and the ear cups do not lay flat to take less space. They also don't come wit a case or pouch, which is slightly disappointing.
Build quality is decent for the AKG K701. They have dense ear cups, and the headband design is flexible enough to handle an above-average amount of physical stress. However, the headband has a lot of moving parts for the adjustable padding. These are potential weak points where the headphones could get damaged through wear and tear, making them a bit less durable.
The AKG K701 have an excellent and even audio reproduction, a spacious soundstage, and low harmonic distortion. Instruments and vocals sound crisp and detailed, thanks to the well-balanced mid-range. The bass is punchy but tends to roll off a bit at the lower frequencies. So you might not feel the deep, rumbling vibrations that some closed-back, bass-heavy headphones provide. Also, the treble range is a tad emphasized, sounding slightly sharp on some tracks.
Good Bass Range response, considering these are open-back headphones. Although there is a roll-off starting at around 42Hz, the lack of sub-bass is minimal. Therefore, these headphones sound a little lacking in low-bass, but bass and high-bass are balanced.
Excellent Mid Range performance. The response is virtually flat up to 2KHz. The 3dB bump in high-mid could push the vocals to the front of the mix and make the sound a bit forward.
Decent Treble Range performance. Low-treble is well produced. The relatively broad bump in treble affects the sibilant sounds and could make vocals, leads and cymbals a little harsh at times.

Very good soundstage. These headphones perform quite well in our PRTF test, which is most likely due to their large and deep enclosures. Also, though these headphones sound open, they are not quite as open as most other open-back headphones.
Excellent imaging. The phase response which is responsible for transparency in imaging, is good and quite flat , but not as good as the HD 800 S. Additionally, the drivers of our test unit were exceptionally well matched.
Very good performance. The overall amount of harmonic distortion is very low, especially at 90dB SPL, but could be considered slightly elevated for ciritcal listening headphones. At 100dB SPL, there is a general rise in the amount harmonic distortion, but it remains within good values.
The AKG K701 like the K702 and K712 are not headphones meant to isolate listeners. They're not made to use outdoors and won't fair well in loud environments. Also, the intentional leakage of the open ear cups 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 isolaton. Due to their open-back design, these headphones don't offer any isolation below 1KHz. Above 1KHz, there is a 3dB/Octave roll-off present, which won't be effective in blocking outside noise.
Poor leakage. Although these headphones are quite loud and leak a lot, the profile of the leakage is narrower that most open headphones we have measured. The roll-off in the leakage above 4KHz is rather uncharacteristic of most open headphones, which makes these headphones slightly less leaky but less open-sounding that the competition.
