About this deal

The cable is a dual entry design, exactly the same as what they do with the Porta Pros, and the ones from the Porta Pros seem to last. The strain relief spring at the 3.5mm end was also a nice touch to increase the durability of the connection. These are very light headphones, and you can just throw them into your bag, and you wouldn’t even notice the added weight that it has. Unfortunately, when they redesigned the adjustment mechanism, they also had to remove the folding mechanism of the headphone, so finding space to bring them along might be a bit of a challenge.

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. Koss Corporation now focuses on what they do best, manufacturing both dynamic and electrostatic headphones and microphones. Technical Specifications 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. Treble

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] 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 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.

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.”The bass in these headphones is present, but not overbearing. The mid-bass is on the leaner side, closer to HD58X levels than Porta Pro levels. For the sub-bass regions, however, it drops off quite sharply, even when compared to more neutral dynamic headphones like Sennheiser’s HD600. Everything pertinent to build and design you could essentially glean from looking at a photo, though; what we’re really here to tell you is how great these headphones sound for such a tiny sum of money. 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.

Many have extolled the virtues of these headphones that cost about the same as a lunch for two at your favorite fast food joint. It’s time to find out if the KSC75 are the giant killers they are said to be. Do they really sound good enough to put headphones many times their price to shame? How do they compare to their numerous brothers and sisters sharing the same driver?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. 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).
