The AKG 712 PRO deliver a great sound for critical listening. They're very comfortable headphones but are a bit bulky and cumbersome for everyday use. They also have an open-back design that leaks a lot and won't block much noise, which is not ideal for loud, noisy commutes.
- Great audio reproduction.
- Comfortable design.
- Open-back design leaks a lot.
- Bulky and unstable headphones.
- No isolation from ambient noise.
The AKG 712 PRO have the same retro design as the AKG 702 and AKG 701. They are super comfortable headphones with large ear cups that are well padded. They're decently built but have a lot of moving parts in the headband mechanism that's susceptible to wear and tear. Unfortunately, they offer no audio controls and are a little too bulky for everyday casual use.
The AKG 712 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 712 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.
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.
The AKG 712 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.
These headphones have a decent build quality. 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.
The AKG 712 Pro have a similar audio reproduction to the AKG 702. They have a good and open sound quality that packs a punch in the bass range. Instruments and vocals are balanced if slightly pushed to the back of the mix. Unfortunately, they can sound a little honky at times compared to the AKG 702, and the inconsistent high frequencies cause a slight loss in clarity and detail. On the upside, they have very low harmonic distortion.
Excellent Bass Range response. Low-Frequency extension of 38Hz is very good for a dynamic open-back design. However, low-bass is still underemphasized by about 3dB, which although subtle, negatively affects the thump and low-end rumble of the sound. The small overemphasis in high-bass adds extra warmth to the sound.
Very good Mid Range performance. Low-mid is a little hyped, which is the continuation of the high-bass bump. At 2dB, the effect is quite subtle, but bumps in low-mid tend to muddy up the mix and add a boxy quality to the sound. The 5dB dip in mid, surrounding 1KHz, could slightly push vocals/leads to the back of the mix.
Decent Treble Range performance. The 2dB dip in low-treble takes some emphasis away from vocals/leads. The overemphasis in treble, surrounding 8KHz, affects the sibilant sounds present in instruments like voice and cymbals. At 10dB this could make the sound a bit harsh and piercing to those with hypersensitive ears.
Good soundstage. Although these headphones sound quite open, they are not as open as the HD 800 S and most of the Grado headphones. We also detected a tiny amount of out of phase crosstalk, but the effect won't be audible. Additionally, these headphones perform decently under our HRTF test, which is most likely due to their large and deep enclosures. This helps in creating a soundstage that is perceived as natural and outside of the listener head.
Excellent imaging. The phase response which is responsible for transparency in imaging, is good and quite flat similar to that of the K702 and HD 650, but not quite on par with the HD 800 S. Also, the drivers of our test unit were quite well-matched, which is key in faithfully creating the stereo image.
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.
These are not headphones meant to block noise or isolate the listener. They leak a lot because of their open back design, which improves their overall sound quality. Sadly, this translates into a noisy headphone that would be distracting to the people around you, even on a bus and at low-to-moderate volumes. They also won't fare well in loud environments and will let ambient noise ruin your listening session if used on a train or while commuting through town.
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.
Poor leakage. These 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.
