If you want deep, full-range sound with larger drivers, choose Audio-Technica ATH-M50X; if you need a more monitoring-focused, balanced sound, choose Audio-Technica ATH-M40x. For college students deciding between studio-style headphones for listening, coursework, or creative work, the key difference is the M50X’s emphasis on deep bass and clarity versus the M40x’s flat-tuned presentation.
• Audio-Technica ATH-M50X: 45 mm drivers, a stated 15–28,000 Hz frequency range, and deep, accurate bass; its trade-off is that its more bass-forward character may not suit someone seeking a flatter monitoring sound.
• Audio-Technica ATH-M40x: 40 mm drivers and flat tuning intended for accurate monitoring; its trade-off is a narrower stated frequency range of 15–24,000 Hz and less emphasis on deep bass.
• Both use a closed-back, over-ear design that contours around the ears for sound isolation, and both have 90-degree swiveling earcups for one-ear monitoring.
• Both are wired headphones with a 3.5 mm jack, so neither is a wireless option for walking around without a cable.
• Choose the M50X if you want a versatile listening headphone with more pronounced bass; choose the M40x if balanced monitoring matters more than bass impact.
The ATH-M50X makes the clearest case for itself with its 45 mm drivers and stated frequency range of 15–28,000 Hz. Audio-Technica describes its sound as clear across an extended range, with deep, accurate bass. That combination is appealing if your playlists move between bass-heavy tracks, vocals, and more detailed instrumentals, and you want one wired pair to cover casual listening as well as focused work.
Its circumaural design fits around the ears and is intended to provide sound isolation in louder settings. For a student studying in a shared room, working at a desk, or listening during a commute, that closed-back layout could help make the headphones a more contained choice than an open design. The 90-degree swiveling earcups also support one-ear monitoring, which is useful for audio work where listening to one side at a time is part of the task.
The M50X is the one I’d consider for someone looking for a full-bodied listening sound without giving up studio-oriented features. Its strengths are the larger driver size, the stated deep-bass response, and the broad frequency range. Those specs do not establish that it will sound better to every listener, though. Someone who prioritizes a flatter monitoring presentation may prefer the M40x instead.

Audio-Technica ATH-M40x: Who It's For
The ATH-M40x is built around 40 mm drivers and a flat-tuned sound intended for accurate monitoring across the frequency range. That makes it a straightforward fit for someone who wants to assess recorded audio, practice mixing, or listen without making deep bass the main attraction. Its stated frequency range is 15–24,000 Hz, compared with the M50X’s 15–28,000 Hz. That difference is a specification, not proof that one headphone will sound preferable to every listener.
Like the M50X, the M40x has a circumaural design intended to isolate sound in louder environments, along with 90-degree swiveling earcups for one-ear monitoring. It is also wired and uses a 3.5 mm jack. The included accessories listed for this model include a cable, a coiled cable, a protective case, and a screw-on adapter. For a student or home creator moving between a desk and different audio setups, those included items may be useful; the sheet also identifies a 6.3 mm snap-on adapter.
The M40x’s appeal is its monitoring-first approach and its practical studio features, including detachable cables and a single-side cable exit. Its main compromise for a general listener is that the sound is described as flat-tuned rather than specifically focused on deep bass. If you want your music listening to feel weightier at the low end, the M50X is the more natural match on paper.
Who should skip it: Skip the M40x if you want the more pronounced deep-bass character described for the M50X, or if you need wireless listening.
• Best for deep bass listening → Audio-Technica ATH-M50X. Its description specifically calls out deep, accurate bass, making it the more obvious fit for bass-led playlists.
• Best for flat-tuned monitoring → Audio-Technica ATH-M40x. Its sound is described as flat-tuned for accurate monitoring across the frequency range.
• Best for a broader stated frequency range → Audio-Technica ATH-M50X. It is listed at 15–28,000 Hz, while the M40x is listed at 15–24,000 Hz.
• Best for a larger driver specification → Audio-Technica ATH-M50X. It has 45 mm drivers; the M40x has 40 mm drivers. Driver size alone does not determine sound quality, but it is a clear design distinction.

My Verdict
Think about how you’ll use the headphones most often before choosing between these two. If your priority is enjoying music while studying, the M50X’s stated deep-bass response and extended frequency range point toward a more engaging listening profile. If you need to hear audio in a flatter, monitoring-oriented way for editing or mixing, the M40x’s tuning is more closely aligned with that purpose.
Neither model is wireless: both are wired and have a 3.5 mm jack. That is a practical consideration for students who want to move around while listening or whose devices do not have a compatible headphone connection. Check your device and setup before deciding, rather than assuming the jack will suit every use.
Both models have over-ear, circumaural designs intended to provide isolation, and both swivel for one-ear monitoring. The M40x has detachable cables and comes with listed cable accessories, a protective case, and an adapter. Those details may matter if you want to connect to different audio equipment or keep accessories together. The M50X’s strongest distinctions in the provided specifications are its 45 mm drivers and its stated 15–28,000 Hz range.
If you’re comparing what each offers for your needs, check the current price on Amazon using the page’s button. I wouldn’t choose solely on the driver numbers or frequency ranges: the practical decision is whether you want the M50X’s described deep bass or the M40x’s flat-tuned monitoring approach.
For general music listening alongside studying, I’d lean toward the M50X because its sound description specifically includes deep, accurate bass and clarity across an extended range. The M40x is a stronger match when flat-tuned monitoring is more important.
Is the ATH-M40x better for mixing than the ATH-M50X?
The M40x is described as flat-tuned for accurate monitoring, so its stated sound profile better suits that particular goal. Both headphones have swiveling earcups for one-ear monitoring and a closed, over-ear design intended to provide isolation.
No. Both are wired headphones with a 3.5 mm jack. If wireless listening is essential, neither model fits that requirement.
