I'll focus on comparing this with the highly acclaimed Koss Porta Pro. Both headsets are new, so they haven't been "burned in" by having hours of music played through them, which many audio experts claim can open up the sound to be even better than when new. (Instead of my 20-year-old Porta Pro, I'm using a brand new Porta Pro Limited Edition, so that neither headset has benefited from burn in.)
COMFORT: Initially the KPH30i is more comfortable than the Porta Pro. for 2 reasons: 1) its kidney-shaped earpieces are larger than the round earpieces of the Porta Pro, so the pressure is more distributed. 2) The KPH30i has a soft rubber suspension band that sits atop the head, while the Porta Pro has a narrow, unpadded metal band that sits atop the head. The clamping force is reasonable, just enough to keep the earpieces from slipping. I wore these headphones comfortable over my eyeglasses. It doesn't appear that the foam cushions are replaceable; they may be, but I don't want to risk pulling the cushions if they're glued on. The Porta Pro cushions are replaceable.
SOUND: Excellent, especially at this price which is about $15-25 less than various versions of the Porta Pro. If you love the famous sound signature of the Porta Pros, you'll probably love the sound of the KPH30i, because the drivers are probably very similar, if not identical (both are rated at 60 ohms impedance, frequency response of 15-25,000 hertz, efficiency of 101 dB SPL. Both headsets produced the same ample loudness from my Samsung S8+ cellphone.) Both headsets being semi-open designs, they both offer a large "soundstage", which means that the voices and instruments don't sound entirely as if inside your head, but also sound as if the sound sources are around you, with broad stereo imaging. I played the same music on both headsets, and the KPH30i sounded nearly identical to my non-audiophile ears. Steve Guttenberg wrote that the Porta Pro is more transparent and clear, while with this KPH30i: "Treble detail is soft, the KPH30i isn't by any stretch a high-resolution headphone. There's a fuzziness to the sound to be sure, but it didn't intrude or detract from the music." He still loves the KPH30i, and I do, too.
Like the Porta Pro, this KPH30i has a 4-foot, non-removable cord. The cord is thicker than the one on the Porta Pro. The KPH30i has a straight plug; I wish it were angled so that it wouldn't protrude 90 degrees coming out of the cellphone. A nice feature is that the plug has a spring-like coil that offers strain relief where the cord joins the plug. Overall, th KPH30i appears very well constructed and I'm guessing it will be durable if handled carefully.
November 21st, 2018: I see that the Koss website sells replacement cushions for the KPH30i. Five dollars for 2 pairs, available in either gray or blue colors. The blue version is for the white KPH30i, but why not go crazy and place them on your gray KPH30i? ;-)
March 10th, 2020 update: I improved the comfort and sound with 2 products available on Amazon: Yaxi earpads for Koss PortaPro (they also fit on these KPH30i) which bring more comfort and audio improvement, and HIDIZS S3 Portable Headphone Amp/USB C DAC/Audio Amplifier which plugs directly into the USB Type-C jack of my Samsung S9+ cellphone.
I am an audiophile. Audiophile: a HiFi enthusiast.
With that out of the way let's discuss these little gems. I can't stand (personally) the description of if a thing is good for it's price. Price may not be subjective but what a thing is worth in relation to how it sounds is subjective on a good day. Instead truthfully if a thing is good it's good, if it's worth it it's worth it. These my friend are good and worth it.
At just a tick beneath the price of the Koss Porta Pro you get the KPH30 and it delivers. So let's look at what you get and what you should expect.
1. Koss' Limited Lifetime Warranty. It's broke, they fix it. Pretty straight forward and admirable considering the intended use of these guys. I'm pretty gentle on my stuff but one trip through Amazon reviews for earbuds and you'll quickly find out the number one reason most people go for a new set is 1. damage like one side no longer playing music and 2. people love to loose thier stuff. Nothing Koss' can do about number 2 but they've got you covered on number 1 so there's that.
2. A lightweight highly comfortable headphone in nice, clean, modern colors. None of that "hey, come steal me" appeal you get from some pricier fashion cans. If you let people listen to them then yeah, expect friends, family members and co-workers living that earbud life to totally swipe them. They're really quite good.
3. Practical usage. No, these aren't really for exercise or blasting music (at a desk anyway) as there will be sound leak. You can't use them to hide from your kids or ignore your spouse. But if you're jamming out to James Brown, Daft Punk or whatever your jam is snapping fingers and doing your step they do not fall off. I have a very large head. I honestly have never been to a Lids or New Era or Belk or something and found hats in store in my size. I always have to order. That being said, larger ears and all they stay on my head with no pressure, heat or discomfort. No "headband" markes on my head or hotspots. All day comfort.
4. Yeah I mean, they're plastic. So's your cars bumper so that doesn't mean it's cheap'o. The point is they're cheap but don't feel built to a price. The adjustment is easy and holds it's place. They don't squeak or creak or otherwise flop around or do things that ".99" dollar store headphones due, contrary to another person's review.
5. SOUND. All caps because that's the number one for most people. If like me, you've listened to lots of headphones, earbuds and in ear monitors you will understand that jumping from one particular sound to another can be jarring. These sound better than the Apple Earbud if that's your concern, the OG ones that end in 3.5, the lightning ones don't sound as good or the same as the old ones. These sound about like Sennheiser HD558's but with better bass presence. The highs are present, sounding more recessed than rolled off. It's not quite like they took away the highs but more like the pulled them back to be non-fatiguing. Bass is solid but not boomy. There's no mid-bass bloat. As a matter of fact the mids are very well positioned not quiet forward but the music, bass and vocals are equally the star in these. The details are there but not the focus, wich makes them well suited for jamming out or long listening sessions more so than critical listening They're warm. Bass is tight and with weight. The bass goes deep but not hi end sub-bass tremble sort of deep. I could keep spitting out descriptions off the top of my head but suffice to say, it's like the Sennheiser HD558, but more involved. It's a warm sound with highs tamed as to not be aggressive and fatiguing, still has detail, bass is good and solid enough to satisfy for rap, dub and edm but controlled enough and restrained enough to not interfere with the mids, male vocals or jazz. To me these are on point for jamming out at louder volumes, relaxed listening while reading, while working, loosing yourself in the music, and phone calls. No one could tell I was on a headset vs my phone without me specifically mentioning it. They're $30 and a hell of a lot better than your stock earbuds or some cheap $10 or $15 one over all.
If you want more treble energy and a more in your face sound the Porta Pros are the better buy. But don't over think it like these are some super dark sounding phones. There's still more treble energy than V Modas or the HD598cs. Not comparing them, just saying if you want every box ticked from comfort to function to sound to being able to listen to them all day. These ARE outstanding.
I bought these to have something that still sounds good to use with my LG V30 other than my in ear monitors. I wanted to be able to take calls and hear things around me. I also wanted to have an open air sound like earbuds (not in ears) and open back headphones give you. But in a tidy, easy to travel or store package. For when I'm cooking or washing dishes or cleaning or just reading my Kindle. I didn't want in your face great sound that's hard to deal with after an hour. I didn't want a saong and dance requirement to manage the cables or put them on and take them off. I didn't want to always have to hot pause to speak to someone. They met everyone of my desires with aplomb. Best of luck and I hope this was at least somewhat helpful in your purchase decision.
However. Once I turned them on, I was almost irritated with how great they sounded.
I'd say they compare favorably to much more expensive headphones. They lack the very low extension, midrange clarity, and sparkle that a $150+ headphones have. But how could that possibly be a negative? They are almost there.
I hooked them up to my Magni 2 amplifier, and they -really- came alive.
The microphone, additionally, is very clear and they are great for making phone calls.
The only caveat I have here: The headphone band doesn't expand super far. If you have a big head, they might be a touch uncomfortable.
Update - While writing the review I decided to listen some more to the Koss and Amazon headphones. Huh? The Koss is now coming across more efficiently than the Amazons'. I don't understand that unless initially I didn't have the Koss headphones centered on my ears properly. At any rate, the Koss has a nice fuller and more open sound stage. I try to listen to what is going on in the background and the Koss presents a more natural drum rim shot. Other instruments in back also sound natural. So, I have to give the Koss more credit. They are really growing on me. The reason for one less star is because of the foam ear pads. I don't think they will last very long.
