Bass. Both have a similar bass according to graphs. I found the K52’s to be fairly tight, balanced and well defined without having too much roll off like the K240 Studio. However, neither are a bass heads headphone specifically. Learn more:AKG K240 Studio Review.
Driver. The drivers are different on both. What is a headphone driver? The K92’s driver has a small hole in the front and a vent hole in the back while the K52’s does not. Taping off that vent hole results in a considerably better sound. It improves the mid-range in that it’s not as harsh, but also results in a loss of treble detail. That said, both have 40mm drivers.
Treble. The treble on the K52 is less harsh/sibilant than the K92. The K92’s has a pretty rough peak at around 5-7kHz. What does Sibilant mean?
Mid-range. The mid-range on the K92 isn’t as prominent, and vocals/instruments do suffer as a result. The K52’s is a bit more forward in this regard. I found them to be very revealing, crisp, and accurate.
Aside from that, these are markedly similar headphones with an almost identical frequency response. While I enjoyed the sound of the K52, I think there are better options around this price range.
In this price range there are a few open backed options to consider:
The AKG K240. Fantastic mid-range, great overall clarity, good comfort factor, but build is questionable.
The Sennheiser HD558. Same as above, with pristine comfort and a pretty good build. Better than both of the above mentioned.
Grado SR80e. More of a fun listen, with added bass emphasis and an alarmingly revealing character. Build is questionable but will suffice, and comfort is good (the 80e’s have the S cushions). Learn more:The best Grado headphones!
The Philips SHP9500. The best out of the lot. A bit bulkier, but feels extremely solid in your hand, with some small features that make it stand out: Right and Left indicators on the outside of the vent in big block letters, and the headband adjustment features a window for easy matching on both sides. Sound is near impeccable, and comparable to an HD600. In fact, it may be better than the Gold Standard.
As for a closed back, the K52 is pretty good (gets mixed reviews) but there’s something better on the horizon: The Sony MDR V6. This is my go to entry level closed back, and for good reason. It’s stood the test of time (made in the 80’s), and has a remarkable sound signature in addition to being very comfortable and durable. While the K52 may feel a bit flimsy in the hand, the V6 certainly does not. Many folks complained about the K52’s long and cumbersome cable. With the V6, you’re getting a fairly compact coiled version, and it does fantastic in studio as well as on the go. Interested in learning more about the V6?
