Build Quality (7.5/10): The design of the HA-M750 has a sort of purposeful hard-edgedness to it. From the rectangular cups to the forked hinges to the thick stainless steel headband, everything feels solid. There are no rattles in the structure and the folding action is smooth and precise. Though they don’t have the collapsibility of, say, the AKG K81DJ or JVC’s older HA-S700, they fold into a reasonably small package that’s easy to store. The cabling is a little plasticky for my taste but long enough for portable use. The included extension is a nice touch.
Comfort (7.5/10): The headband of the HA-M750 is well-padded and wrapped in pleather. The clamping force is neither too soft nor excessive. The pads are made of memory foam and covered by an even softer material than the headband. The foam is quite compressible and does a very good job of conforming to the shape of one’s ear. However, the pads can “bottom out” when the foam is compressed, causing one’s ears to touch the grilles. This happens to me, and while it doesn’t bother me for a few hours, it can get tiring in the long run. The only other issue I have with the M750 is that the pleather pads can induce sweat, but that is no unexpected in a closed, circumaural portable.
Isolation (8/10): The JVCs do isolate a fair amount although the restricted range of motion of the cups as well as the fact that the pads “bottom out” on my ears probably don’t help matters. Rubber rings mounted on the grilles help improve isolation if they make a good seal with your ears
Sound (6.5/10): The sound of the JVCs manages to be very full and rich but at the same time surprisingly balanced. The bass is quite deep – extension is better than the K81Dj and about on-par with the CAL!s – and well-textured. If the mids weren’t so forward these could easily be classified as bass-centric cans, but the whole signature is pretty aggressive, which helps the balance at the expense of a mediocre soundstage. The midrange is thick and creamy, causing them to lag behind the K81Dj in separation and clarity. The timbre isn’t quite as natural, either, and the tone is on the dark/warm side of neutral. Overall, the M750 did a great job of keeping me entertained without being overly colored or absolutely true to the source.
Value (8.5/10): The JVC HA-M750 is a reasonably-priced circumaural headphone that provides an excellent compromise between comfort, isolation, portability, and sound. Though they don’t sound as natural as the AKG K81Dj or as fun and dimensional as the Creative Aurvanas, they aren’t lacking in any particular area and are cheaper than both, making them very easy to recommend.
