Koss PortaPro vs Jabra Elite Sport (2017)

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.

In this mode, the mic picks up audio from your surroundings. You can hear sound from around you mixed in with your music.

There is an integrated heart rate monitor which can connect to Jabra's fitness companion app. This combination should make it very easy for you to see fitness related data.

The Elite Sport sounds quite balanced with no harshness or muddiness. The highs are clear and deliver good detail. Mids sound natural and rich, while the bass is tight and controlled instead of bloated. With these headphones, you will get decent punch from the usually bass-centric workout tracks, yet you will still be able to enjoy a refined sound when listening to more mellow or instrument focused music.

These resist sweat and other liquids as they are IP67 rated. They can be submerged in water without getting damaged as long as the water is not too deep and they are not submerged for a long time.

You can attach wing tips to the earpieces, which allow for better in-ear fit for reduced chances of the earpieces falling off. The tips are quite soft so they will not have too much of a negative impact on comfort.

Each earpiece has two buttons which you can use to control playback or to answer/end calls.

The charging case has an internal battery that can add up to 6 hours to the Elite Sport's battery life.

There are microphones integrated in the ear pieces so hands free calls are possible. Voice quality from the mic is actually pretty good.

You get a charging case, 3 pairs of silicone ear tips in different sizes, 3 pairs of premium Comply ear tips in different sizes, 3 wing tips in different sizes as well as a charging cable.
