Koss - Porta Pro

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.

I own three of these supremely comfortable pair of headphones. They have excellent sound quality, are highly portable, and come with a decent carrying case.

First impressions I got from this headphones are as follows:
1.they feel fragile and cheap.
2.they have a very different
design philosophy which
makes them standout in
crowd.
3.they have a very 'balanced'
sound signature.
4.they have a very comfy pair of
cushions/foams.
5.they have a fitting system
which requires some getting
use to.

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.

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.

Koss Porta Pros are a weird purchase if you're buying them in India. They are not the budget monsters they are in the west, as they are moderately priced here. What they do offer over many other headphones are two things - comfort and a non fatiguing warm sound. If you like a combination of both, you'll love these headphones.

It reminds me of Senn PX 80 but much improved version. Very warm, slighty boosted bass and smooth sound that you can listen long without any fatique. Truly remarkable for the price and can even compete with the likes of Senn hd 58x, 6xx and so on with sound signature. This along with their brothers KPH 30I and KSC75 serves the audiophile starter package at much lesser cost. Hpz, pls add the other two in your catalog. Honestly I can even live with these for "on the go" fun and little bit of critical listening as well. I don't miss much of my HD6xx and Sundara for casual listening. Highly recommended and must buy !!

Tiny headphones that have a big punch. It's impressive how good the sound quality is on these. The bass is emphasised but doesn't cause any dip in quality.

Hey guys im shivam from chhindwara madhy pradesh and this is my 10 th headphone that is so insanely beautiful sounding.
