Specs/Graph

Shoutout to Samma3a for the graph!

Check out what he had to say, a sentiment I happen to agree with:

Looking at this average, I’d say that it’s at least pretty close to how I perceive the sound signature to be. I’m not sure if that large dip at just beyond 4kHz is due to the measuring rig or perhaps some resonance from within the earcups, but I can’t say that this is something which I could pick up on when listening to them. As we can see, the signature is surprisingly well-balanced and it’s only really in the upper treble frequencies that I think the KPH30i would have benefited from a bit more energy.Samma3a

I also do not perceive that dip. Seems a bit strange and not indicative of how the headphones actually sound. Outside of that, the graph is very good.

Let’s get into the review.

Soundwise, yes; they are perfect. What makes this even more astounding is when you consider the fact that I heard these after hearing 100+ other headphones. That’s right, you heard me correctly.

The semi-open-backed KPH30i for $20-30 sounds better than the majority of them, and that’s not an exaggeration. Call me crazy, but I’d consider this a budget Utopia. The keyword being budget. Related: Focal Utopia Review: Best In The World?

It is really flimsy and feels rather cheap, but guess what, it is cheap. This is to be expected, but it’s still incredibly economical and efficient; a no-frills, utilitarian, somewhat retro design. We’re listening to music, not making a fashion statement, yeah mate?

Comfort is pretty average. It sits pretty well at first, but the On-Ear design will start to dig into your ears after a while. Get some Yaxi Pads or something. Whatever. I paid $20 for it. The people who complain about these headphones are probably the same ones complaining about getting only a slightly above-average Blow J.

WAHH it’s not good enough! I paid $20 whole dollars which is my life savings!

I EXPECT BETTER wahh!

GET A GRIP!!

The good news is that it doesn’t dig into the top of your head much, and the thin piece of rubber is to thank for that. A strange design surely, but very effective.

What about it stands out?

Putting one on your head is a revelation of sorts. There’s nothing about it that sounds out of place, over-emphasized, weird, or wrong. This is what makes it stand out. It’s simply a perfect-sounding headphone. I can’t really point out a single flaw with it. This is outrageous considering its price. All of the hype surrounding the 30i is completely and absolutely warranted without question.

It’s the one thing that most audiophiles agree on unless you’re this goofball:

“The 30i sounds cloudy!”

Lol, I haz a funny.

Actually, I thought it was mostly sunny with a chance of awesome!

It’s one of those things that can only be appreciated in retrospect. After hearing a lot of good headphones, some mediocre, some amazing, and some terrible, the 30i is most certainly a breath of fresh air.

The mid-bass thumps without sounding bloated like a 40x, the treble is detailed and crisp without sounding neither too veiled nor too bright, and the mid-range is just sublime. Vocals and instruments stand out, but in a way that isn’t too shouty or in your face. If there was ever a “perfect” sound signature, I think the 30i would be as close as it gets. For an On-Ear headphone, the Soundstage here is quite good. What is Soundstage? [Detailed Explanation] It’s not a K702, but what is. It’s definitely above average and has no business sounding this open and spacious, especially for its price. Instruments are spaced out nicely and the music is given ample room to breathe and express itself.

I fully recommend for most people to bypass everything you may have heard about, and just go straight for the 30i as your intro to the hobby.

Koss KPH30i Review

I talk a lot about the MDR-7506 and SHP9500 as perfect entry-level headphones (and they still mostly are), but the 30i outclasses both because there aren’t any glaring flaws with its sound.

If you’re looking for something more durable and comfortable, the 9500 is it. Its sound is a close second. Almost perfect, with that treble caveat. Still, paired with the hip-dac, Q1, or K5 Pro helps a bit.

YAY, SYNERGY!

The 7506 comes in third because of the earcup issues, annoying non-detachable coiled cable, and sometimes overly bright treble. Still, it’s a solid option and I think everyone should have one in their headphone cabinet.

Both the 9500 and 7506 have some treble issues but by and large, are still products I recommend because of how amazing they both sound. They currently reside in the #1 and 2 spots in my Budget Kings series, but the 30i will most certainly take the top spot after this review.

This is also significant because the 9500 has held the crown since I started the series back in 2018. Many headphones have come and gone, but the 9500 always occupied the top spot.

As of now, everything drops a spot and the 60e is gone.

HE GONE!!

Good riddance.

Amplification

You won’t need an amp for the 30i, but I’ve found it to work quite well with anything I may have lying around. How to Choose a Headphone Amp [Definitive Guide]

I think a great pair would be something like a BTR3K. You can listen at home wired or on the go via Bluetooth. It’s incredibly convenient because the 30i’s cable is short and compact, and the headphone is highly transportable. You can wear this bad boy on your neck without looking like you just walked out of a Head-Fi meet with a duffel bag full of overpriced DACS.

Final Word

If The 7506 is pure sound, and the 9500 is pure-er, the 30i is definitely the pure-est. It’s an experience you won’t soon forget and a headphone that personally changed my life and made me re-evaluate music all over again.

So buy one today. It’s $20. Chump change. You really have nothing to lose, and most certainly everything to gain. This is a headphone you’ll cherish for a long time, perhaps even forever.
