Koss PortaPro vs 1more Triple Driver

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.

There are two balanced armature drivers which handle the production of high frequencies, resulting in highs that are really detailed and have a lot of sparkle and detail to them.
The 2 BA drivers are complemented by a dynamic driver (hence the triple driver designation) which handles the mids and the lower frequencies. Mids are smooth and clear while the bass is powerful yet at the same time is well controlled.

The earpieces' tips are slightly angled and allows for a more comfortable, deeper and more secure fit in the ears.

The headphone cable is covered by a fabric sleeve. Not only does this make the cable look and feel expensive, but this also adds to the cable's durability. This also helps prevent the cable from tangling easily.

The inline remote has a metal casing with three buttons that allow you to control tracks, respond to calls as well as adjust the volume.

The remote is compatible with Android and iOS devices.

These in-ears incorporate a lot of metal in the build, with the earpieces, the in-line remote as well as the 3.5mm plug predominantly made out of metal. This gives the headphones nice heft and a quality feel.

The in-line microphone allows you to take calls without having to disconnect these headphones. Microphone sound is rich and has good clarity.

Along with the headphones, you also get silicone and foam ear tips in multiple sizes, a leather carrying case as well as an airplane adapter. These are functional accessories that definitely add a lot of value to the overall package.
