Koss PortaPro vs V-MODA Crossfade M-100

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.

The M-100's sound signature can work really well with a wide range of music. Bass reproduction has good power and punch. The mids are also full and slightly forward over the other frequencies. This results in extra emphasis on the vocals and on mid-range sounds like guitars and keyboards. The highs are not peaky, which reduces their harshness, sounding smooth instead.

These headphones come with a SpeakEasy Mic cable and a Share Play cable. This gives you an option as to which cable you want to use at a given time. This also means that you will have a spare cable should you damage the other.

These have a solid, high quality feel to them, and you can tell that they will last you a long time. The ear cups are made of high quality plastic, while the headphones' yokes and headband are made of metal. The headband has a generous give yet does not feel flimsy at all. You can even twist it quite a bit yet it still won't feel like it will break.

The yokes can be collapsed and folded up into the headband. This reduces the overall size of the headphones, making them much easier to carry around.

You can detach the cable by simply pulling out the 3.5mm connector from the port on the headphones. The connector attaches with a satisfying click so it is less likely to get disconnected when in use.

The SpeakEasy cable has an in-line microphone with great noise cancelling. The cable also comes with an in-line 1 button remote which allows users to answer or end calls, as well as pause and play music tracks.

The SharePlay Cable features a 3.5mm pass-through port where a person can connect their own headphones. This means that you and another person can enjoy music from the same source.

Included is a clam-shell style case made of durable plastic so it should protect your headphones from scratches and minor impacts. Do note that you will have to detach the cable to make it fit inside the case.
