Koss PortaPro vs Bose SoundSport In Ear

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 output is very good. It has good power yet at the same time is fast and punchy. It does not bloat the sound at all. The highs and mids are able to deliver a good level of detail that makes the sound quite lively. These will work best for bassy tracks, though rock, jazz, classical and pop will still sound enjoyable.

In stock form, these headphones have a relatively short cable. However, Bose includes an extension cable for extra reach. This can help to minimize the wire length that you have to deal with when going for a run or exercising.

The earbuds can resist small splashes of liquid or sweat. The hydrophobic cloth material wrapped around the headphones helps to minimize issues relating to moisture.

The specially designed Stay Hear ear tips have a wing design which helps to add grip to the earpieces when worn. This helps to ensure that the headphones will not easily get dislodged when on the move.

The ear tips are very soft and flexible. Combined with the ear bud design that does not jam into your ear canal, these are a joy to use in terms of comfort, even for extended periods.
