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.

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.

8.0 Comfort
Weight : 0.65 lbs
Clamping Force
:
1 lbs

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.

5.5 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.

5.2 Portability

W : 7.28 "
H : 4.33 "
Volume : 253.74 Cu. Inches
Transmitter required : N/A

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.

5.5 Case
Type : Pouch
L : N/A
W : N/A
H : N/A
Volume : N/A

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.

7.5 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.

7.1 Breathability
Avg.Temp.Difference : 3.9 C
Cable
Detachable : Yes
Length : 9.8 ft
Connection : 1/8" TRS

The AKG K712 PRO come with two audio cables. A 1/8" TRS and a 1/8" TRS coiled audio cable.

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.

3.6 Leakage
Leakage Audio
:
Overall Leakage @ 1ft
:
55.56 dB

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.

AKG Q701
SEE PRICE
Amazon.com

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 has 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 no 20-foot cable like the Q701 have. They are still very similar headphones, but the higher price on the K712 might not be worth the investment for the little differences.

Conclusion

SEE PRICE
B&H
6.0 Mixed Usage

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

8.0 Critical Listening

Great headphones for critical 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.

4.8 Commute/Travel

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

5.3 Sports/Fitness

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

5.5 Office

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

6.1 TV

Above-average for Home Theater. They're sufficiently comfortable and the open and a well-balanced sound suitable for watching movies. However, since they're wired headphones, they won't have the best range. Unless you have an extension cord for the audio cable, they won't be the best headphones, to comfortably watch tv from your couch.
