Open-Back Design

Headphones with an open-back design, allow air to pass through the earcups. This means that Open-Backs do not block any noise from around you, as closed-backs do, and music being heard will also leak outside to people around you. So they can only be heard in a quiet environment.

However, Open-back headphones do sound more natural and open. Open-back headphones create a feeling of space, presenting audio as if you are sitting at a live concert. Audiophiles swear by open-back headphones, and they sound quite different to closed-backs.

These headphones are perfect for critical listening sessions, mixing and mastering music. They have an accurate soundstage presentation and precise imaging.

Needs Amplification

Headphones and IEMs require a certain level of power to sound their best and work at their full potential. When your headphones or IEMs are underpowered, they can sound thin or muffled.

Amplifiers are required to provide adequate power to your headphone or IEMs to perform at their best. Simply put, amplifiers allow a weak audio signal to be boosted to a powerful one.

To put it into perspective, devices such as your phones and laptops come with an amplifier, but they offer very limited output power. This output may not be sufficient to power headphones and IEMs to shine at their best. This is where a dedicated amplifier is required to deliver adequate power to hear your music in all its glory.

Audiophiles should take note that the KOSS Porta Pros uphold their renowned status. The sound quality is immaculate, characterised by precise bass that maintains balance. The continued favour these headphones enjoy is well-deserved, attributed to their outstanding sound performance.

Excellent value for the money

tl;dr: For the price paid, these headphones sound terrific and truly punch above their weight.

Going into detail, these are very comfortable and so lightweight that very soon, one forgets it's on your head. These do need to be handled with some care. The clamp is good with three levels of clamp provided to accommodate various head sizes. It's an open headphone so sound leaks in and out. Good luck to listening with these while walking on busy streets (especially in India). And that's a shame since these headphones are a delight to listen to.

The sound is not really balanced. It's weighted towards the low end. The bass is powerful and there is good texture. It can feel one-note though depending on the music. The mids are nice and detailed and for the most part is not overpowered by the bass; there is a bit of treble roll off. All of this makes for an easy listening. The sound stage is really wide relative to the size of the drivers. And these are easily driven out of the smartphones available today.

Bottom line: For the price, this is an easy recommendation to buy. I detest IEMs and a strict desktop guy with DAC/Amps/circumaural headphones. However, I will make an exception for the Koss when I'm moving around.

Thank you so much for the detailed review.

Tanmay (Chandigarh)

When I saw them first time online, I was intrigued by their design. Classic 1984 built, it's nothing like the others. Here's a thing. They're slightly fragile and tiny. They're not for everyone. They're not strong and tough and they do give a cheap feel but I embrace it fully given I love vintage stuff. Once you put them on, they're amazingly soft and you would forget that they're on top of your head. Plus they're really small so you get that nice portability factor to it. These are strictly not for the bass lovers out there. It has a very balanced and warm sound. They're not very clear either, you can't expect to hear every slightest detail but again, they're balanced. The very essence of a balance is that you cannot be inclined towards one thing. For casual listening, they're absolutely exceptional. They can be folded even further so that just contributes to its portability. Highly recommended if you need them for casual listening and don't mind the vintage design.

Missing the clarity sound of Porta pro

This koss porta pro is 2nd one, previous one got it from other online source. The 1st one was working fantastic untill the cable sheath on one side of earpiece worn-out and broke out. Based on the previous experience ordered this piece. This piece sound clarity is not good as it's muddy except mids are ok. The clarity of sound is missing in this piece and tried with different sources , even with Spotify same condition. Not sure, this is a defective piece and I am unlucky to get a defective one this time. Looking at the warranty/return policy and with my busy schedule, I decided to stop here without further actions
Comfort wise this is a topper.
