The Sony h.ear on MDR-100AAP are average over-ear headphones, with an eye-catching design and a decent sound. They're lightweight and fairly stable, but they struggle a little in loud environments. They don't block much noise and also leak a little at higher volumes.
The Sony MDR-100AAP are great looking headphones. They have a similar design to the MDR-ZX770BN but with more flashy color schemes. They're lightweight, above-average comfortable and will stay in place during casual listening sessions. However, they won't be stable enough for the gym. They have a poor control scheme and their build quality is mediocre at best. They feel a little plasticky and fragile.
The Sony MDR-100AAP are stylish looking headphones. Their overall design is similar to the MDR-ZX770BN. However, the earcups have a distinct style that looks a bit better than the 770BN. They have bold and bright color schemes, which are eye-catching but also come in an all-black design for those that prefer less flashy looking headphones.
The Sony h.ear on are above average comfortable headphones, thanks to their lightweight design. They exert the right amount of pressure around the ears and don't feel too tight. Unfortunately, the earcups are a little smaller than some other over-ear headphones, which may become uncomfortable for some, during long listening sessions. Also, the padding on the earcups and headband, although soft, is not that thick. Luckily this doesn't reduce their comfort level by much.
These headphones have a mediocre control scheme that offers minimum functionality. They have only one button on their inline remote, which provides call/music control. The button has a good tactile feedback. However, the lack of volume controls is slightly disappointing.
The Sony MDR-100AAP are mid-sized over-ear headphones like the MDR-ZX770BN. However, these headphones fold into a more compact format, which makes them slightly more portable. They will fit into smaller bags once folded but are too cumbersome to carry around, on your person. They won't fit into any pockets, even larger jacket pockets.
These headphones have a decent build quality but feel a little flimsy, like the MDR-ZX770BN. They have the same thin metal frame and moderately dense earcups that can handle a couple of drops without breaking. They also strengthen the earcups' hinges by making it swivel less than the MDR-ZX770BN. Unfortunately, the overall design still feels a little plasticky and not durable. Also, they may get faded and scratched by regular wear and tear, which will be a little more noticeable because of the bright colors.
These headphones are moderately stable. Their lightweight design and decent tension, prevents them from swaying too much during physical activity. However, these are not sports headphones, and they will slip off your ears if used while running or doing high-intensity exercises in the gym. On the upside, the cable is detachable and will disconnect before yanking the headphones of your head if it gets hooked on something.
The Sony MDR-100AAP are a decent sounding pair of closed-back over-ear headphones. They have a good bass, a nearly flawless mid-range, and a good treble. However, their bass is over-emphasized and sounds boomy, and their treble is slightly veiled. Additionally, their bass delivery may vary a bit from person to person, their distortion levels are on the high side, and don't have an open soundstage.
The Sony h.ear on MDR-100AAP only have passive isolation. They will struggle a little in loud environments unless you listen to your music at very high volumes. They don't block much ambient noise and would not be ideal for busy commutes or noisy flights. They also leak a little and will be audible to the people around you at higher volumes, especially in a quiet office or library.
Poor overall isolation. Considering these headphones don't have active noise cancelling, the passive isolation provided in the Treble Range by the ear cups is quite decent. But the passive isolation only becomes effective past 400HZ and does not really block any low/bass frequencies. Isolation in the mid-range is also below average.
No active features.
