The Koss Porta Pro KTC deliver a good sound at an affordable price. They're lightweight, comfortable, and have a portable, retro design that will work for some. However, they feel flimsy and cheap, they don't block any noise, and the open design leaks at higher volumes.
- Lightweight and comfortable design
- Above-average audio reproduction.
- No isolation from ambient noise.
- Weak and flimsy build quality.
- Leaky at higher volumes.
The Porta Pro have a straightforward, retro design that will work for some but may look too cheap for others. They're lightweight, comfortable and don't exert too much clamping pressure for an on-ear model. The KTC version of the Porta Pros comes with a convenient but poorly built control module. Unfortunately, they're not very durable headphones. They're flimsy, have a lot of moving parts, and the audio cables are thin and non-detachable. On the upside, they have a pretty generous lifetime warranty.
The Porta Pro are extremely lightweight for on-ear headphones. The headband is flexible and easily adjustable, which makes them above-average comfortable. They're not too tight, however, they do have an adjustable tension slider on the ear cups. It doesn't change much to the fit but its a nice addition to the design. Unfortunately, they're poorly padded so they don't provide any extra comfort apart from their lightweight fit.
The KTC version of the Koss Porta Pro comes with an inline control module that provides call/music, track skipping, and volume controls. This is a definite upgrade from regular Porta Pros as it gives some control over your audio. However, the buttons on the module feel cheap and shallow. They don't provide a good tactile feedback and are bit frustrating to use.
These headphones have a moderately stable fit. The lightweight and relatively flat ear cup design makes them not sway much when used while running. However, they're not the most stable headphones. The slight lack of tightness, means they might fall off during high-intensity exercises and the audio cables are a little bothersome and non-detachable. They will yank the headphones of your head if hooked on something
The Koss Porta Pro fold into a small, compact format that's easy to carry around and even fits in some pockets. They're on the smaller side for an on-ear model, which combined with the unique folding mechanism makes these headphones quite portable. They will easily fit into most bags and shouldn't be too much of hassle to carry on your person.
The build quality of these headphones is subpar and feels cheap. The headband is a thin metal frame with no padding and an awkward sliding mechanism to adjust its size. The ear cups are not particularly dense although their lightweight build makes hard falls less damaging. Unfortunately, they don't feel durable. They have a lot of moving parts that will wear over time. The audio cables are thin, frail and could snap relatively easily from regular use. On the upside, they come with a reliable lifetime warranty as long as your able to send the headphones back to Koss.

These headphones are not meant to isolate listeners from ambient noise. The open design means they let a lot of ambient noise seep into the ear cups to produce a more immersive listening experience. Unfortunately, this also means they won't be ideal for loud environments, like commuting via public transit. They also leak quite a bit and would not be suitable to use in quiet settings, as they might distract the people around you.
Poor isolation. Due to the open back of these headphones, the isolation is weak by design. They barely isolate any external sound, failing to achieve more than 6dB of isolation in the treble range.
Poor leakage performance. The Porta Pro's open-back design leaks a lot, even though on-ears are usually not very leaky. The significant portion of leakage is between 1Khz-20KHz, which is quite a broad range. The overall leakage level is also quite loud.
