Koss "Porta Pro" On Ear Headphones

Product Information

If you gravitate towards great midrange, and a healthy and open sound stage, this will be a great option for you. It manages to keep the vocals clear while not taking too much away from the highs or the lows. 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

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. 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! In 2020, Koss sued Apple, Bose, JLAB Audio, Plantronics Inc., and Skullcandy for patent infringement. [10] In July 2022 Koss and Apple reached a settlement for an undisclosed amount regarding the alleged patent infringement on Koss' intellectual property [11] 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. A close look at the KSC75. Bass

Disclaimer: The KOSS KPH30i sent to us is paid for and not a sample in exchange for our honest opinion. The KOSS KPH30i was recently promoted via Drop and you can find more details here. 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. The KPH30i use the same non-coated version of the driver shared by the Porta Pro amongst others. KPH30i Sound 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. 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.

Again, no surprises here. The sound quality of the KPH30i punches way above its weight class. They more than hold their own in the budget Koss lineup and absolutely deserve distinction from their peers. Midrange frequencies are the star of the KSC75 show and are reasonably balanced. Vocals stand out in the mix, and voices sound consistent and natural if a touch thinner and less warm than is my ideal. The detail is really quite good, and things sound clear and clean. TrebleThe 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. Headphones with a dynamic element positioned just outside the ear, connected to a tubular port structure that inserts into an expandable cushion 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. More powerful amplification can open them up a bit, but don’t expect miracles if you plug these headphones into a source costing 20 times more. The overall sound signature stays reasonably consistent regardless of what is driving them, but a little more oomph doesn’t hurt. Bass 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.

These headphones are not that hard to drive, at 60Ω, and 101dB SPL, I can even drive them off a smartphone. You won’t get the best of them through your phone though, as driving them with better gear does have its benefits. 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. 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. Incorporated a neodymium, rare earth magnet and 16-micron mylar diaphragm for deep bass and treble clarity 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.
