I’ve seen HD600’s from the ’90s that are still around until today, so that’s truly a testament to the build quality. But the KPH30i is much lighter on the head, and would really be nice of longer listening sessions.

The KPH30i is a headphone that you might think you can easily find if you would rummage through a computer parts bin, but it truly is a gem in the rough. Although it’s not exactly portable, with the solid and unfoldable frame, it’s light enough and durable enough to be thrown into a bag when you need to bring it on some trips.Koss lists the first Key Feature of the KPH30i as “spacious sound & deep bass.” While “deep” may be debatable, this is a reasonably accurate depiction of what you can expect. The untreated Koss driver typically delivers a low-end focus, and the KPH30i are no exception. The very depths of the sub-bass aren’t really reproduced, but overall the bass region is articulate and conveys solidity and weight. While similarly voiced, the Porta Pro are the deeper and more bass-heavy option, with the KHP30i sounding a bit more balanced and even. This comes somewhat at the expense of fun, and I find the Porta Pro more exciting to listen to. The limited treble extension and smooth reproduction is surprisingly fairly similar sounding between the two, regardless of the differences in measurements. Where to Buy The KSC75 can be driven sufficiently from any device with a decent headphone output, and pairing them with a source that is many magnitudes of cost more expensive doesn’t seem to improve the sound significantly.

It took me a while to get to listen to them, but when I had the chance, I couldn’t put them down anymore. So I ended up buying a pair. Guttenberg, Steve.

You can toggle between a light or firm fit – though firm does not mean clamped – as well as collapse them down to fit tidily in your bag. I (and many others) have gone on at length about the superb 60ohm, 35mm driver found in the Porta Pro, Sporta Pro, KPH30i, and the KSC35. Koss uses a titanium-coated version in the UR40, KTXPro1, and KSC75. This extraordinary driver defines this legendary series of headphones and has been in constant production and daily use for almost four decades! Koss headphones with the 60ohm driver are important staples in the portable headphone industry. a b Barrier, Michael (1990). "Life after near-death - Koss Corp. near bankruptcy". Nation's Business.

Like the Porta Pro® Classic headphones, the Porta Pro® Wireless Bluetooth headphones have adjustable temporal pads to relieve pressure on the ears. Its lightweight, open-air cushions for hear-through sound keep listeners aware of their surroundings while delivering exceptional sound performance. Oxygen free copper voice coils and dynamic elements allow the Porta Pro® Wireless Bluetooth headphones to deliver rich bass and a remarkably wide frequency response.

I’ll be exploring plenty of pad options in a soon-to-be-published Koss modification article. Internals The acclaimed Koss Porta Pro® has captivated audiophiles and music enthusiasts for decades and continues to be one of the most popular headphones worldwide.The KPH30i is not much of a looker, in fact, it could easily be lost in a computer parts bin. Once you touch it though, you would realize that these are quite different. The plastic that was used is quite a bit more durable than the generic ones, and I wouldn’t be surprised if these last me for a few years. The cup connection is a big departure from the other Koss headphones in this series that share a snap-in ball construction and allow for headband exchanges. The somewhat fragile headband slider mechanism and silicone comfort strap. If your budget stretches further, we’d still suggest opting for the AKGs: they’re a more serious sounding product that improve on each element of performance – as headphones more than double the price should.

Originally introduced in 1984, the Koss Porta Pro® has stood the test of time due to its impressive performance and portability. Equipped with dynamic elements that deliver a wide frequency response and deep bass, Porta Pro® offers remarkable sound reproduction producing a rich, detailed audio experience that enhances the enjoyment of music across various genres. Without repeating myself too much, the 35 mm, 60 Ohm driver is what makes this range of headphones so special. According to Koss, the “computer-optimized neodymium, iron, and boron rare-earth magnet structures deliver amazing clarity at any volume” and the “oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound.”

Until then headphones had only been used in communications applications. In 1958 the design was introduced at a hi-fi trade show in Milwaukee, and audiences approved of it. Soon after the trade show, Koss went into business manufacturing and marketing stereophones from his basement apartment. The technology was imitated by competing manufacturers. [5] I know, that you know, that I know you know, that I like the 60ohm, 35mm Koss driver. A lot. It’s INCONCEIVABLE that you do not. Princess Bride humor aside, what differentiates the KSC75 driver from the one found in the Porta Pro or KSC35 is titanium. So, what does the addition of a super-thin, super-strong, and super-light metal coating actually do? In practice, it stiffens the diaphragm without adding significant mass, which is intended to boost detail, precision, and clarity.
