Koss PortaPro vs Onkyo W800BT

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.

Instead of being bloated and overpowering, the bass is punchy and fast so while these will not be able to produce a lot of rumble. Thump should be satisfying for most users. The highs are nice and airy with a lot of detail yet never become harsh, so these are not fatiguing to listen to. The mids sound very natural and jump out just enough to make vocals and guitars very easy to hear and appreciate.

These should work best for more vocal and instrument focused genres like jazz, rock, classical and the like. Bass heavy tracks will still sound good with these, though these headphones will not be able to give the deep bass that bass lovers will be after.

The carrying case has an internal battery, and with a full charge, can supply the headphones with 5 full charges on the go.

The soundstage that these produce gives the music an open feel with good instrument separation. This quality will help give the listener an immersive music listening experience.
