The AKG K712 PRO deliver a great sound for critical listening. They're super comfortable headphones with a few more accessories than the K701 or the K702. However, like the previous models, they're a bit bulky and cumbersome for everyday use. They also have an open-back design that improves their overall sound quality but leaks a lot and won't block much noise, which is not ideal for loud, noisy commutes.

Our Verdict

5.2 Mixed Usage

The AKG K712 PRO headphones are not designed for everyday, casual use.

Pros
  • Great audio reproduction.
  • Comfortable design.
Cons
  • Leak a lot, due to open-back design.
  • Bulky and unstable headphones.
  • No isolation from ambient noise, by design.
8.0 Neutral Sound

Great headphones for neutral listening. They're comfortable and have an excellent sound quality that reproduces tracks with high fidelity. They also have an open back design, which gives them a broad and spacious soundstage.

4.1 Commute/Travel

Not optimized for commutes. The AKG K712 PRO don't block any ambient noise.

5.1 Sports/Fitness

Too bulky and unstable for sports headphones. The AKG K712 PRO will slip off your ears while exercising.

4.9 Office

Not intended for office use. Unless you work in an isolated environment these headphones will leak and be distracting.

Style

The AKG K712 PRO share the same design as the AKG 701 and AKG 702 with few minor differences in color schemes. The open-back ear cups are large and circular and covered in a suede-like padding that gives the headphones a premium feel. Sadly, they may be too big and bulky for some listeners and will stand out in a crowd more for their size than their style.

The AKG K712 PRO are incredibly comfortable headphones. The headband design does not put too much pressure on your head. The large ear cups easily fit around most ears but might be a little too large for some listeners. They deliver a comfortable listening experience, but their bulky design is not for everyone.

The AKG K712 PRO are one of the biggest headphones reviewed so far. Like the AKG 702, they are bulky, cumbersome and do not fold up into a more compact format. The ear cups also do not lay flat to take less space and the retro headband design is quite large. This results in a headphone that's hard to carry around, and that will only fit in a backpack or large bag.

The AKG K712 PRO come with a suede-like, fabric pouch that looks stylish and doesn't add much bulk to the headphones. Sadly, it also doesn't offer much protection from falls, accidental drops or water damage.

Design
Build Quality

The AKG K712 PRO headphones have a decent build quality, but not as good as the Beyerdynamic DT 1990 PRO. The ear cups are dense, and the headband design is flexible enough to handle an above-average amount of physical stress. However, the adjustable headband padding has a lot of moving parts. This means a lot of potential weak points where the headphones could get damaged through wear and tear.

5.5
Design
Stability

These headphones like the AKG 702 and AKG 701 are not stable and will easily fall your head if used while doing sports. They're not tight enough and will only stay in place during casual listening sessions. The detachable cable locks into the ear cups and will yank the headphones off your head before disconnecting if ever it's hooked on something. These are not sports headphones, and it shows in their design.

Poor isolaton. These headphones don't offer any isolation below 1KHz, which is expected of open-back headphones. Above 1KHz, there is a 3dB/Octave roll-off present, which won't be effective in blocking outside noise.

Overall Leakage @ 1ft

Poor leakage. The AKG K712 PRO headphones are quite loud and leak a lot, which is due to their open-back design. The profile of the leakage is narrower than most open headphones we have measured, similar to the K702. However, the drop in the leakage above 4KHz is rather uncharacteristic of most open headphones.

Compared To Other Headphones

See our recommendations for the best open-back headphones, the best audiophile headphones, and the best over-ear headphones.

AKG K702

The AKG K712 PRO and the AKG K702 are almost identical save for a few differences in design and frequency response. The K702 get a bit more bass but also sound brighter - unfortunately, to the point of sounding a bit sharp. The K712 will sound less harsh to most people, but their soundstage isn't as impressive.

AKG Q701

The AKG K712 PRO are slightly better headphones than the AKG Q701. Sound-wise, they perform better in the bass and treble range, while the Q701 have a more even mid-range. The K712 also have better frequency consistency, especially in the bass range. People wearing glasses shouldn’t hear any loss in bass. The K712 also come with a pouch and a coiled cable, but not a 20-foot cable like the Q701. They are still very similar headphones, but the higher price on the K712 might not be worth the investment for the little differences.

Beyerdynamic DT 990 PRO

The AKG K712 PRO are slightly better open-back headphones than the Beyerdynamic DT 990 PRO. The AKG are more comfortable, have a much wider soundstage, and are much more consistent among users. The Beyerdynamic are also a bit less bass-heavy, though the AKG are a bit brighter sounding.

Beyerdynamic DT 1990 PRO

The AKG K712 PRO and the Beyerdynamic DT 1990 PRO are both very good audiophile headphones, though they have fairly different sound profiles. The AKG have a very smooth, neutral sound, but lack quite a bit of bass, while the Beyerdynamic sound quite a bit more excited, with a lot more bass and a much brighter treble. They can sound quite sharp and piercing, though, so the AKG are a better option if you're sensitive to sounds in the higher frequencies.

Superlux HD 681

The AKG K712 PRO and the Superlux HD 681 are both great audiophile headphones if you like a neutral sound. They have fairly similar profiles overall, though there are a few differences. The Superlux get quite a bit more bass, and they also sound brighter in the treble range, which gives them a slightly more excited sound profile. They're also less comfortable than the AKG and feel a lot more cheaply made.
