The AKG K702 are great, comfortable headphones for critical listening but are mediocre for everyday casual use. Their open design doesn't block any noise and leaks enough to be distracting. They're not made for commuting or to use at the gym but are ideal for appreciating high-quality audio in a quiet environment.
The AKG K702 have a retro style with large circular earcups that are superbly padded and extremely comfortable. They're not too heavy for their size and have a self-adjusting headband that doesn't put too much pressure on the head. Sadly, this also makes them unstable, quickly falling off your head if used while doing any physical activity. They're also quite bulky and don't have any audio controls, which is disappointing.
The AKG K702 share the same style and build as the AKG K701 and AKG K712 PRO. They have two-tone navy blue and silver color scheme and an old-school retro design that will work for some. The open back ear cups are large and circular and covered in a suede-like padding that gives the headphones a premium appeal. However, they pretty big and bulky for everyday use.
The AKG 702 are very comfortable headphones. The large ear cups easily fit around most ears, and the headband design does not put much pressure on the head. They might be a little too large and bulky for some listeners, but they deliver a comfortable listening experience that does not cause soreness even on long listening sessions.
The AKG K702 like the AKG K712 PRO are big and bulky headphones that are not portable. They do not fold up into a more compact format, and the ear cups do not lay flat to take less space either. The retro headband design is also quite large and results in a headphone that's cumbersome to carry around, and that will only fit in a backpack. There is also no case or pouch, which is disappointing.
Build quality is decent for the AKG K702. They have dense ear cups, and their 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.
These headphones are not tight enough and will easily fall your head if used while running. They're not designed for sports and only stay in place during casual listening sessions. The ear cups will sway and slip off you ears, even during mild physical activity. Also, the detachable cable locks into the ear cups and will pull the headphones off your head before disconnecting if ever it's hooked on something.
The AKG K702 are a very good sounding pair of open-back over-ear headphones. They have a good bass, an excellent Mid Range and a good Treble. They also have a relatively consistent performance across different individuals, and have a good Soundstage. However, their Treble is slightly overemphasized and like most other open headphones, their Bass lack a little bit of thump.
These are open-back headphones, and they will leak a lot to produce a spacious soundstage. However, this means that they're not the ideal headphones for use in public, as your audio will be easily audible by anyone in your vicinity, even at low-to-moderate volumes. They also don't fare well in loud environments. The open design does not block any noise and may ruin your listening experience if used, on busy commute or noisy train ride.
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.
