Koss TWS250i

True Wireless in-ears with neutral sound

In April of this year, Koss already earned an editorial recommendation for the smallest model in their Bluetooth in-ear series. Back then, it was the TWS150i that earned our recommendation thanks to their decent price-performance ratio. Now the next model up in the series reports...

Koss BT740iQZ

Bluetooth over-ears with Active Noise Cancelling

BT740iQZ - A somewhat unwieldy name for what are actually quite elegant headphones that the designers at Koss have come up with for their new Bluetooth model. With active noise-cancelling (ANC), integrated media control and hands-free function, as well as long battery life, these new...

Koss Porta Pro Classic

On-ear, ultra-portable headphones

It must have been around 1988 when I bought my first pair of Koss Porta Pro, on the recommendation of an audiophile friend. In fact, for many people of my generation, the Koss Porta Pro was a widely used upgrade to the bog-standard headphones that...

Editor's recommendations: KOSS

I summed up the TWS150i thus: “Good battery life, elegant design, neutral sound, great range, reasonable price – what else can one say, except to congratulate Koss that they have succeeded with the TWS150i, solid in-ears that make no mistakes sonically.” And I’d say exactly the same about the TWS250i. However, with two additions, because on the one hand I would like to praise the significantly better precision of the touch controls, and on the other hand, the extremely high wearing comfort, because the TWS250i are really almost imperceptible when in the ear. I would say that the rather discreet bass performance is a matter of taste because the lower frequency range is undoubtedly there and is reproduced precisely – just without that extra half decibel boost that makes up the fun factor. Fans of objective sound will appreciate this very much. Lovers of “sub-in-the-head” experiences, on the other hand, might find it too small (without equaliser intervention). I also sorely missed the option to use multi-pairing, because in modern life it’s pretty common to change players (mobile phone, tablet, laptop, etc.). Even if they don’t do everything right: All in all, these comfy and good-sounding in-ears from Koss score very highly on points, even when considering the recommended retail price of 89 euros.

Koss TWS250i

The Koss BT740iQZ got through our test without any slip-ups, and for a reasonable price, you get a pair of Bluetooth headphones that are decent in every respect (sound, wearing comfort, handling) with effective ambient noise cancellation. Their sound profile is aimed more at listeners who are looking for a warm, soft and bass-strong “cuddly” sound and less at fans of crystal-clear, precise and treble-rich sound.

Koss BT740iQZ

With the Koss Porta Pro Classic, you’ve known for almost 40 years what you’re getting for your money: a lightweight, ultra-portable and amazingly robust on-ear pair of headphones that you can hardly tell you’re wearing, whose delicate, timelessly chic design has come to feel retro-futuristic again. What is no longer quite so contemporary is their treble reproduction, which, from today’s perspective, seems perhaps a bit too discreet. Nevertheless, the warm, bass-strong sound of the Porta Pro has a very pleasant character and turns every tram or bicycle ride into a visit to a little acoustic club.
