The Bottom Line:​

The Koss Porta Pro On-Ear Headphones are a great throwback to the 80s. The warmer sound, better build quality, and retro styling all make for an exciting listening experience – one that won’t disappoint anyone who’s looking for their next pair of headphones.

Headphone Design

In 1984, Koss released the Porta Pro alongside another product of theirs called the A-3 Music Box. The latter was a portable cassette tape player, while the headphones’ main function was to give clear sound quality and comfort to its users using the Music Box. The Porta Pro’s ability to fold up into a compact item that can fit into your pocket is one of the reasons they were such a hit in the ’80s. Flash forward to today, the Porta Pro is still going strong! 

An 80s aesthetic paired with a distinctive blue color gives the Porta Pro headphones an amazing look that you will love. The Porta Pro is an on-ear headphone, with an easy-to-adjust spring-loaded aluminum headband that slides into position. There’s also a simple slider switch (Comfort Zone) for adjusting the fit to your preference. The Comfort Zone slider switch is helpful in getting a custom, comfortable fit. 

Looking at cabling, the Porta Pro features a 4ft cable. This is longer than your average pair of headphones, which is nice when you’re listening to music but want to keep your phone in your pocket or backpack. It’s also a perfect length for gaming. 

Headphone Fit and Comfort

These headphones are super comfortable, especially for those who wear their headphones all day at work or travel a lot. The lightweight and almost perfect fit make these easy to forget you’re wearing them – even after extended periods.

The only downside to these headphones is that they sometimes pull your hair, particularly when you try and take them off. When removing the Porta Pro, just be aware of where your hands are placed so as not to accidentally yank out a few strands. I found this particularly painful if my hair was longer than usual because it would catch on to the gap between the sliders and the headband. 

Sound Quality

The Koss Porta Pro are excellent sounding headphones, especially considering the price! These aren’t bass-heavy headphones so don’t buy them expecting to be blown away by big bass sound quality. Instead, these accurate-sounding cans have an exceptional clean tone across all frequencies of music production. The clear low-end combined with the forward mid-range delivers a clean, flat sound that is full of life. This will provide listeners who like natural-sounding headphones a pleasant experience.

More Koss Porta Pro Models

Including the original model, there are actually nine different models available in the Porta Pro range. Let’s take a look at some of the others below. Feel free to either click on each model’s image to jump straight down or simply scroll down.

Koss Porta Pro Wireless - Speakers Reviewed

Koss Porta Pro Wireless

The Porta Pro Wireless looks nearly identical to the original Porta Pro, just without a cable. Instead, there is a short wire that fits behind your neck and connects to each earpad. The wireless headphones feature Bluetooth 4.1 with apt-X or high-quality sound encoding which provides as good as a wired listening experience for up 12 hours on a single charge (most of its competitors last only 10). Like the Porta Pro Mic/Remote model, the wireless version also has a three-button inline remote with a microphone, volume control, and multi-function buttons for play/pause and incoming calls like most Bluetooth headsets.
