The sound, sound stage, isolation are everything a person would want form studio type headphones. Flat tuning and not be assumed lifeless or boring. As the word neutral is to sound signature one can expect there not be any lift in any part of the spectrum and my ears don't pick up on any. The sound stage is actually better than I expected. Case in point, the quiet opening vocal to Dire Straits' "Money For Nothing. Those vocals literally come floating in slow from left back and pan across to take up space on both channels. A brilliant bit of audio engineering and these phones bring it to you with accuracy and detail. The isolation is appropriate to the closed back. These headphones will play well from a smartphone but scale exceptionally with better amplification so not power hungry at all but benefit from a larger amplifier. A larger amp lifts a little tiny bit of vail that lower powered devices just can't shake off.
The design, fit and build are where I take a little issue. Nothing specifically wrong as opposed to just not to my liking.
The design is actually great. Well thought out and brilliant in it's simplicity. The cups are securely mounted to a gimbal and spin nearly 180 degrees and will lay flat on a table or in the included and very rugged case. This genius bit of design lefts these fold and articulate in ways my beloved MDR-v6's just wont. The cups themselves, for me aren't full over ear, they are on-ear. They aren't at all uncomfortable but they bug me and they don't tick the "full size" box for me. A personal issue, not wrong but I still don't like it. Because of the on ear nature they took some fiddling to get them to line up well. Sound suffers if you don't have them positioned right, as does comfort. Get them right and it's surprising how things change the "D" shape of them assists with this. The pads are quite comfortable however and don't become tiresome after long periods of time.
The build is mostly plastic, the cups and sliders are the exception. The cups being aluminium. The sliders are painted metal; probably spring steel and feel sticky when adjusting. This is another small point of contention for me. There are no adjustment detents either, a feature I really like on other headphones of the same ilk.I'm not crazy about the coiled cord. I like coiled headphone cords. I really wish more headphones had them, this one is lust a bit short for my tastes. I like to put the music on, spin away from my desk and lean back. One isn't spinning and leaning far with that short cable. The termination is adequate. I could find beef with it but I imagine it can be replaced easily.
Why with all of this nitpicking did I still give this product a 5 star review? It's a great headphone. I got it for $99 but even at $149 it's a great headphone. For the professional and the avid listener, especially the critical listener that wants the music as it was intended. It does smooth treble without a whisper of sibilance. The mid range is superb but it's not forward at all It presents vocals and mid instruments right where they put them during mixing, tracking etc. the bass isn't overpowering nor is it anemic and it extends further lower than you'd except. It's right. It's as much as the engineers/artists intended.In tremendous detail. They sound "right". The fit while not necessarily my cup of tea is comfortable. Despite those small spoiled gripes this is a great headphone at a fair price that will probably last for years. That backed with the excellent Koss warrantee, there's no reason to ever have a bad experience. Send them in with 9 bucks and done. AND, they're made right here in the good ol' U.S. of A.
Let's start with clarifying: these are studio headphones, not consumer headphones (for those, see the equivalent Koss SP540). Studio 'phones and monitors are meant for listening during the recording process to fine-tune the overall sound quality to ensure it delivers as expected. These tend to have a more balanced sound profile, where the bass, mids, and highs tend not to overpower each other and the sound is much more detailed. Cans like these are going to cause you to notice things like picks hitting the strings of the guitar, or the occasional double-tap with the drum stick. Consumer headphones (Beats, Bose, V-Moda, most Sennheiser) are for the actual end-user, listening to the finished product. These are typically tuned to deliver heavier bass levels or softer trebles (sometimes, both).
That said, the Pro4S is more like a designer khaki. They're meant for work, but I'm not in a rush to take them off at the end of the day. They look and feel great, with very solid build quality and smart design. The included coiled cable is as equally solid, utilizing a nice thick gauge of wiring. I mostly wear these while doing some editing work because a lot of what I do normally involves compression, which typically results in quality loss, and I try to keep that to a minimum. However, I've found myself wearing them more and more often lately to simply listen to music or watch movies. Isolation is spectacular and the D-shaped ear cups are so comfortable that I now debate making these my go-to cans for everything.
As mentioned, since these are studio cans, the sound profile is rather neutral. It is worth mentioning, however, bass response is noticeable and taut, versus the echo-y punch delivered by more popular headphones. Mids and highs come in clear, and I've yet to encounter any distortion while listening to source material.
Final thought: it's a shame (and possibly a good thing) Koss isn't as popular as Beats, because the sound quality they deliver is far superior.
Pros: excellent sound and build quality; very clear sound delivery; quite possibly the best headphones I've bought myself that don't require amplification or other dedicated equipment
Cons: Clarity and detail can be distracting at times when listening to old favorites; Koss labeling tends to evoke thoughts of K-Mart for some
