About this deal

The high-frequency reproduction is resolving enough to provide a decent feeling of detail, and the KPH30i are reasonably articulate. They don’t extend to the top-most highs, and the treble remains polite and non fatiguing. This sound profile works great for long listening sessions (especially with audiobooks). The diaphragm receives an extremely thin layer of titanium bonded to its surface. Titanium is a popular choice for driver manufacturers as it has the highest strength-to-weight ratio of any metal. Titanium sure does make the driver super shiny! Headphones with a dynamic element positioned just outside the ear, connected to a tubular port structure that inserts into an expandable cushion 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. 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.

The Porta Pro share the same cable as the KSC75, but in every other way, they are better built, more attractive, and offer greater comfort than their ear-clipped relations. If you prefer the Porta Pro sound but want a midrange price point and ear clips, the Bluetooth KSC35 are a viable option. 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 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. The only issue that I can see with comfort is that they seem to be a bit loose on the ears, leaving me with a less than optimal seal around my ears, and the sound would probably leak quite a lot from these. Isolation

Although I don’t think the KHP30i are poised to supplant the Porta Pro, others may disagree. While retro-styled, the KPH30i are less distinctively and divisively styled than the 1984 designed Porta Pros. The cable and comfort are (perhaps) an upgrade. The KPH30i sound almost as good to my ears, and they are significantly less expensive. The rubber ear cup connection points are red and blue. 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. Incorporated a neodymium, rare earth magnet and 16-micron mylar diaphragm for deep bass and treble clarity

Let’s be honest with each other. The KSC75 look and feel every bit of their oh-so-low price tag. Shiny silver plastic never seems premium or expensive. And yes, one can draw unfortunate parallels with the free headsets offered on airplanes. The clear rubber-covered metal ear clips are the highlight of the design, as they are smooth and sturdy.I’ve seen complaints about the cable’s longevity, but I have Porta Pros that are decades old and have this same cord. It’s not fancy, but it’s entirely serviceable. The fixed cable does tend to get snagged easily, and if you are like me, you may find yourself accidentally pulling the KSC75 off your head fairly frequently. The distinctive 45 degree Koss 3.5mm plug. Design It’s great to see that Koss still stands behind their lifetime warranty on their budget products. Cable It’s seemingly the most difficult aspect of a presentation to get right – considering just how many products at all prices we hear getting it wrong – but timing is absolutely these Porta Pros’ forte, and the rhythms they deal are done so with an infectious vivacity.

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] In the late 1970s, to accommodate rapid growth, Koss moved to its present location on the north side of Milwaukee. [ citation needed] John C. Koss founded the J.C. Koss Hospital Television Rental Company in 1953. [3] After a short time Koss was looking for new ideas, and partnered with Martin Lange to eventually develop a stereo headphone. Based in Milwaukee, Wisconsin, United States, in 1991 Koss Audio & Video Electronics started producing and selling consumer electronics products as a separate company in Hazelwood, Missouri, United States. The Koss family owns more than 75% of the firm.Originally introduced in 1984, the Koss Porta Pro® hasstood 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. In-Line controls on the Porta Pro® Wireless Bluetooth headphones allow users to wirelessly change songs, answer/end calls, change volume, and much more*. Compared to its much older and more venerated sibling, the KPH30i is no slouch. In terms of build quality, I would say that it’s a toss-up between the two. If your need is to bring it along on the road a lot, then I think the Porta Pro’s build is more suited for that kind of use. A microphone is integrated with the in-line controls giving users the ability to talk wirelessly on the phone, record audio and control their source device*.

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. I’ll be exploring plenty of pad options in a soon-to-be-published Koss modification article. InternalsThe rubber strap at the top of the headband is also a nice touch as it properly distributes the little weight that the headphone has on my head, which means that I can wear these headphones for hours, without feeling their weight on my head.
