The AKG K701 Headphones are comfortable and breathable critical listening headphones with 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. Now, let’s we read the below review to know more.
AKG K701 Headphones Review
Design & Build Quality
The AKG K701 Headphones 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 a 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.
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.
Of course, these extra features really aren’t to be expected in studio headphones – sound quality is where the money is really at. Unsurprisingly, the K701 doesn’t disappoint.
In fact, the term ‘hi-fi’ may as well have been coined to describe these headphones. They boast a full frequency range with decent bass, a great mid, and an out-of-this-world treble. The crystal clear highs and smooth lows make the K701 fit for a whole range of genres, from classical to metal. However, it may not be the best choice for modern, bass-heavy genres; especially seeing as they have a 300 hour break-in time.
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.
But boy, is the clarity unmatched after that! The analytical capabilities of the headphones are nothing short of astounding. Each note is distinct and you’ll hear even the slightest recording error. If this is the kind of performance you require, the K701 won’t leave you wanting.
Noise Isolation & Leakage
Poor isolation. Due to the open-back design, the AKG K701 Headphones don’t isolate below 1KHz. Above that, they achieve about 12dB of isolation, which is sub-par.
Poor leakage performance. A 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.
In conclusion, Great sound quality for neutral listening. The AKG K701 Headphones are super comfortable and have great audio reproduction. Bass mids and treble are well balanced, and the large and open ear cups give these headphones a spacious and immersive soundstage. Their treble can be somewhat inconsistent a bit sharp but overall they have a good sound that will please most neutral listeners.
