Koss PortaPro vs Panasonic ErgoFit HJE120

The drivers may be small and thin, but there is good bass presence.. The mid-range may not be the most detailed, but there is a smoothness to it that gives the sound a warm and pleasing quality. There is a slight roll-off to the high frequencies yet detail and extension is still good . Overall, these headphones can give a fun listening experience that can work well with all genres of music.

Koss provides a lifetime warranty for these headphones.

The ear cups can be folded into the headband. This further reduces its already slim design into something that is much more compact. When folded down, these headphones can easily fit in small bags.

The headband can easily be adjusted to fit a user's head. The assembly features sliding metal pieces which can easily be set to fit small to large heads.

Aside from headband adjustment, users can also adjust the clamping force of the ear cups using the Comfort Zone system. This changes how secure the ear cups attach to the headband, which results in either a loose or tight clamp.

These are eye-catching headphones because of their retro design. The unusual shape of the driver case and the blue accents definitely make these look unique.

These headphones may look thin and flimsy, but are actually much more durable than their look suggests. The headband is made out of metal and can take some flex without snapping. The plastics used also exude a quality feel.

When used on the go, these headphones get extra protection from the included carrying pouch. This pouch looks simple and is made out of pleather, which should protect these headphones from scratches.

Bass is controlled and tight, yet still gives a bit of an oomph. This is unusual for the price range. There is good detail in the overall sound with clean highs and recessed but still present mids.

Overall, these in-ear headphones work great for genres like rock, pop, hip-hop and the like, though the lack of overall refinement in the sound means that these are not best suited for classical or jazz music.

Due to the in ear design, the tips create a good seal in the ear canal. This helps block off some sound and will allow you to better focus on your music.

The ErgoFit comes with three pairs of ear tips in different sizes. This gives users some degree of control as to the seal and comfort that these in-ears can have

Aside from the standard black, these come in red, yellow, green and a myriad of other colors. Whether you are after in-ears that are subtle looking or want one with louder colors to match your personality or mood then there is a variant for you.
