+ great overall sound quality, probably unbeatable at this or even double this price
+ potent but not overbearing bass; fairly neutral mids and highs; no listening fatigue
+ comfortable and secure fit (I have a big head); they stay put moving around, jogging, working out
+ continuously adjustable headband (no notches) helps achieve ideal fit
+ on-the-ear design with soft pads so ears don't get warm/hot
+ foldable for portability
+ open back design makes it sound more like listening to speakers in a room instead of music just focused inside your head
+ open back design lets outside sounds in so you're aware of surroundings (great for jogging)
+ lifetime warranty (haven't used yet; if you're careful, these shouldn't break)
- bass doesn't extend super low; not much bass output below about 50 Hz
- for electronic and rap/hip-hop music, lack of very low bass is an issue with SOME songs. MOST songs sound fine.
- open back design will leak what you're listening to into the nearby environment
- headband may occasionally pull a hair; adjust the band BEFORE placing on head and do not adjust while on head to prevent this
- occasionally a small hair may get stuck inside the driver causing a slight rattling noise; gently remove earpad and blow out the hair to fix
- earcups pivot slightly for comfort, but mine developed a creeky noise when pivoting in the left earcup; sometimes audible during listening
These are by far the best sounding headphones I've heard anywhere near their price range. I honestly think you'd have to spend at least 2-3 times as much to get better sound. They are also the most comfortable headphones I've ever worn: very adjustable, ears don't get hot, stay firmly put with just the right amount of pressure. It's easy to see why they've been around for about 30 years and their design hasn't been significantly changed. "If it ain't broke, don't fix it" applies here. Very highly recommended. Please let me know if you found this review helpful by voting on it. Thanks!
The latest pairs appear to be manufactured differently; they have issues with sliding the plastic tabs over the metal strap, popping and muddled sound, and a plastic cover where the screw was on the left can. I had assumed initially that this was a change in the manufacturing process, that is until I received a pair of the special edition Koss PortaPros that were recently release, which were identical to my previous pairs in every way except the color-way. So either the generic colors are being manufactured differently or the headphones I have received are not authentic.
I will say these headphones are usable, though having owned multiple pairs the pairs I have received do not live up to my expectations. My review for the previous pairs of headphones would be 5 stars, unfortunately the latest pairs I have received do not deserve the same rating.
I have attached photos comparing the build quality of a previous pair I own to that of what I received from Amazon. You'll notices differences in the molds used to cast parts of the headphones. These capture some of the issues but its hard to explain the feeling of what appear to be tight manufacturing tolerances and warped plastic.
Really, it's kind of staggering how great these sound for this price. I'm no expert on the tech side of things regarding audio, but I can tell you the sound is crisp, the bass is low and impactful, and the highs are pleasingly lacking in screech and tinny-ness (that's how I'm going to word that; sorry... haha).
Koss doesn't have the best reputation in the world as far as consistent quality, but this model is one of their high points. Here's a breakdown to get right to the point:
--They just sound good. My eyes kind of went wide when I kicked these on through my iPhone (first tried out "We The People" from A Tribe Called Quest because of that great beat right off the bat and was not disappointed, obviously). As I said above: good highs, good lows.
--They are very comfortable. They have a "Comfort Zone" switch from low to high, the pads (which swivel!) are nicely -- well -- padded, and there's another buffer of foam that sits just above your ears to take some of the pressure off your ears as well.
--They are VERY light. Since they are simply headphones attached with a thin metal strip, they seem to weigh nothing at all, a huge bonus for long-term users.
--If you take them off to adjust them, they will probably not pull your hair, which is a common complaint I've seen in these reviews. Do not adjust them while on your head, and you'll likely be fine. I've never had a single hair-pull.
--They accommodate a very large head at maximum adjustment. My head is large enough to have it's own gravitational pull (Thanks, Mike Myers!), and these fit PERFECTLY.
--The cord is not very long, and for my tastes -- especially given these are being sold as PORTAble -- that's VERY appealing. There's nothing worse than doing dishes or cooking and getting your headphone cord stuck around a drawer knob, thus ripping the phones off your head and sending you into a rage that ends nations. The shorter cord mitigates that global tragedy.
--I think they look cool!
--Yes, just one con for me so far: they make my ears hot. However, this is more of a personal problem; most people I know do not have this problem, but if I put ANYTHING on my ears, they are red-hot within minutes. So, ignore this con if you're a normal human being and not approaching the surface temperature of the sun every few hours. If the pads can be traded out for nice leather ones or something, I am not aware of that although I have looked on Koss's website where the pads can be bought.
In short: If you need a spare pair of 'phones or even a single pair for most situations (probably not great for exercise, however; dunno), you really can't go wrong with these. Thumbs up from this fella!
