If you want a lightweight, simple wired monitor for a big head, choose Audio Technica Studio Monitor; if you need detachable cables and swiveling earcups, choose Audio-Technica ATH-M40x. The first is the more straightforward pick for tracking and field recording, while the M40x offers more monitoring flexibility and cable options.

Neither is wireless, and neither product sheet gives a head-size range, so I would not treat either as a guaranteed fit for every big head. The practical differences are in weight, cable setup, and earcup movement—not a documented difference in headband sizing.
Audio Technica Studio Monitor vs Audio-Technica ATH-M40x at a Glance
• Audio Technica Studio Monitor: Its 220 g listed weight, foldable design, and 3.0 m cable suit stationary recording and portable storage. The trade-off is a fixed cable.
• Audio-Technica ATH-M40x: Detachable cables and 90-degree swiveling earcups make cable changes and one-ear monitoring easier. The trade-off is that its listed bundle offers more accessories and components to keep track of.
• Both are wired, closed-back, over-ear headphones with 40 mm dynamic drivers and sound-isolating designs.
• Choose the Studio Monitor for a straightforward, lighter wired setup; choose the ATH-M40x for flexible cable options and one-ear monitoring.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The Audio Technica Studio Monitor listing identifies the headphones as the ATH-M30. It is a wired, closed-back design with 40 mm drivers, a 15–22,000 Hz frequency response, and 47-ohm impedance. Its stated focus is detail and mid-range definition, with a circumaural fit intended to help isolate the listener in noisy environments. That makes it a reasonable spec-based fit for studio tracking, mixing, and field recording.
At 220 g without the cable and connector, it is the lighter option according to the provided figures. The cable is a 3.0 m straight lead with a left-side exit. The headphones fold for storage and include a carrying pouch and screw-on 6.3 mm adapter. Those details favor someone who wants a simple wired monitor that can be packed away without a more involved cable setup.
I would skip it if detachable cables or swiveling earcups are essential. The cable is listed as a fixed straight lead, and there is no stated one-ear monitoring feature. For someone shopping specifically for a big head, the listing gives no headband range or fit measurements, so the lower listed weight is useful context but not proof of a particular fit.
The ATH-M40x is also a closed-back, over-ear wired monitor with 40 mm dynamic drivers and a circumaural design intended to reduce outside sound and sound bleed. Its 90-degree swiveling earcups support one-ear monitoring, which is a practical feature for DJ work or recording situations where a listener may need to keep one ear free.
The clearest advantage over the Studio Monitor is cable flexibility. The listed bundle includes both a coiled cable and a straight cable, and the headphone’s cable is detachable with a left-side connection. The package also includes a carrying pouch and a screw-on adapter. That setup makes more sense for someone moving between a desk, a recording space, and other wired listening situations, or for anyone who wants the option to replace or swap the cable.
The trade-offs are that the supplied information does not give the M40x a comparable weight figure or frequency-response range, making a direct numerical comparison on those points impossible. It also does not provide headband measurements. If comfort for a big head is the deciding factor, do not assume the swiveling cups answer that question; they enable monitoring flexibility, not a documented head-size fit.
• Best for a lighter listed build → Audio Technica Studio Monitor. Its stated weight is 220 g without cable and connector. The M40x’s supplied listing gives no directly comparable figure.
• Best for a fixed, long straight cable → Audio Technica Studio Monitor. Its 3.0 m cable exits on the left and is described as straight.
• Best for swapping cables → Audio-Technica ATH-M40x. Its detachable setup comes with both coiled and straight cables.
• Best for one-ear monitoring → Audio-Technica ATH-M40x. Its earcups swivel 90 degrees, supporting that use.
• Best for a simple field-recording kit → Audio Technica Studio Monitor. The pouch and 6.3 mm screw-on adapter are included, and the headphones fold for storage.
• Best for DJ or singer monitoring flexibility → Audio-Technica ATH-M40x. The swiveling cups and two cable styles give it a more adaptable setup.
• Best for someone focused on stated audio figures → Audio Technica Studio Monitor. Its listing provides frequency response, sensitivity, and impedance; comparable figures are not given for the M40x here.
• Best for a big-head fit decision → Neither can be confirmed from the listed specifications. Both are over-ear designs, but neither listing provides headband dimensions or a fit range.
Searches for an “extra bass kids headset for big head,” “wireless headphones for big head,” or “open ear earbuds for big head” point toward different priorities from these monitor headphones. Neither model is described as wireless, open-ear, or a children’s headset, and the supplied information does not characterize either as an extra-bass option. If your priority is specifically wireless listening or an open-ear design, these two wired closed-back monitors are not a direct match.
My Verdict
Neither listing provides headband measurements or a stated head-size range, so the specs cannot establish which will fit a big head better. The Studio Monitor has a listed weight of 220 g without its cable and connector; that is not a substitute for fit information.
No wireless connection is listed for either model. Both are wired headphones, so choose between them based on their cable arrangements and other features rather than expecting wireless use.
The Studio Monitor has a 3.0 m straight cable with a left-side exit. The ATH-M40x has a detachable left-side cable and its listed bundle includes both coiled and straight cables.
The ATH-M40x is the clearer fit for one-ear monitoring because its earcups swivel 90 degrees. The Studio Monitor’s supplied features do not list swiveling earcups.

• PHILIPS Headset vs LEVN Headset: Headphones for Office
