Koss "Porta Pro" On Ear Headphones

Product Information

There’s also a surprising amount of bass weight, without skewing or muddying the balance, and while their treble is perhaps not the sweetest we’ve ever heard, it is far from coarse or distracting. 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 acclaimed Koss Porta Pro® hascaptivated audiophiles and music enthusiasts for decades and continues to be one of the most popular headphones worldwide. The 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.

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.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.

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.Koss eventually branched out into creating home theaters, DVD players, portable media players (MP3), 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.

With desktop DAC’s, I tried the iFi Zen DAC, and it sounds great with it as well. Given that the iFi will sound a bit warmer than the Dragonfly, The KPH30i did not sound too boomy nor did the bass overpower the midrange. I can say that the KPH30i plays nicely with both since the headphone is very neutral, to begin with. Compared to the Porta Pro, the KPH30i hold their own sonically. Where they fall behind is in build quality, with the Porta Pro proving to be the much more robust of the two. Many will find the KPH30i headband to be more comfortable, and the plastic and silicon band avoids pulling out hairs when adjusting.
