Koss "Porta Pro" On Ear Headphones

Product Information

They are available in four colors, with the grey/black and white/blue versions looking particularly modern and the rhythm beige and (new) clear versions ‘clearly’ targeting retro enthusiasts.

What’s left of my hair always seems to get caught in them and their headband adjustment doesn’t seem to be able to stay in place. The KSC75’s looks are entirely functional, but they are likely not going to be embraced by fashionistas. I’m also pleased with the battery of these wireless headphones, which Koss rates to last for more than 12 hours and which I’ve yet to fully exhaust even once. In an era where visual storytelling is paramount, our team of photography enthusiasts is dedicated to bringing you the latest camera news. Many will find the KPH30i headband to be more comfortable, and the plastic and silicon band avoids pulling out hairs when adjusting.The driver mounting mechanism is the same design found on the Porta Pro and the KSC35, which means that the bands and clips are interchangeable. Without repeating myself too much, the 35 mm, 60 Ohm driver is what makes this range of headphones so special. For me, music is everywhere, and I just don’t want to let the gear get in the way of listening to the purest form of music. Where the KSC75 have more upper energy and seem slightly more resolving, the Porta Pro have more presence, although with bass heavy music they can tend towards boominess and bloom.

Koss says it’s looking into the issue, though it feels like an obvious oversight not to have addressed it before release. Eschewing the ear-clip style of the KSC35 and 75, the KPH30i are a traditional on-ear style with a plastic headband. Shout out to my current listening and reading obsession, the superb (and unbelievably voluminous) Wandering Inn series by the mysterious pirateaba.Many have extolled the virtues of these headphones that cost about the same as a lunch for two at your favorite fast food joint. Koss eventually branched out into creating home theaters, DVD players, portable media players, tabletop stereo systems, and boom boxes but has since closed the “Koss Electronics” line. The dynamics were immediately extended, and the background became much darker than on any regular phone.

One was Koss TV-Rental, which also did electronics and musical instrument repairs; the second was the main facility two blocks to the east. Its distinctive retro aesthetic, lightweight design and adjustable headband ensure a snug fit, while the foam ear cushions provide long-lasting comfort during extended listening sessions. Like the other Koss headphones sharing the 60 Ohm (impedance), 101 dB (sensitivity) driver, the KPH30i can be driven reasonably easily by most portable devices. For the sub-bass regions, however, it drops off quite sharply, even when compared to more neutral dynamic headphones like Sennheiser’s HD600. To him, the added convenience of having these already lightweight headphones detached from any other device is a liberating and highly desirable feature.Their combination of low wearing pressure and open-back design yields a respectable sound stage, with decent instrument separation. By profession, I’m an electrical engineer, and I use my engineering background to make sound decisions on audio purchases, and decisions. Low frequency response is very limited, likely due to the titanium-coated diaphragm’s stiffer nature and perhaps the unique driver housing and venting. If you gravitate towards great midrange, and a healthy and open sound stage, this will be a great option for you. When creating the KOSS BT539i, the main emphasis was placed on compactness, namely: miniature D-shaped cups, thin headband and minimal weight.

With better upstream gear, the midrange is even better, it adds a bit more clarity and dynamics to it, giving life to the vocalist, further separating him/her from the other instruments.You can trust our unbiased assessments to help you find the ideal headphones that match your unique preferences and needs.
