The MDR-7506 vs M50x debate pits two of the most popular closed-back studio headphones against each other. Both are sealed, foldable, and a fixture in home and professional studios. The Sony MDR-7506 is a bright, detailed, lightweight workhorse aimed at tracking; the Audio-Technica ATH-M50x has a fuller, bass-forward sound that many find more enjoyable for general listening.
Quick answer: Choose the MDR-7506 for an analytical, detail-revealing sound and light comfort during long tracking sessions. Choose the ATH-M50x for a richer low end, more substantial build, and detachable cables. Both are closed-back and well-suited to recording.

Sound signature
This is the core difference. The MDR-7506 has a bright, forward upper-midrange and treble that makes detail, sibilance, and editing problems jump out — exactly what you want for catching mouth clicks, checking takes, and tracking. Some listeners find it slightly harsh over long sessions or fatiguing on bright material. The M50x has a fuller, more bass-weighted balance with a smoother top end, which sounds more pleasing on music but can mask some low-end detail and is a touch less revealing of flaws. Neither is perfectly flat; both are popular precisely because their character is familiar and predictable.
Use for mixing
Closed-back headphones like these are excellent for tracking — their isolation stops the backing mix bleeding into the microphone. For mixing, treat both with care: the M50x’s elevated bass can lead you to under-mix low end, while the 7506’s brightness can lead you to over-tame highs. Use them to spot detail, but always cross-check critical decisions on monitors or true reference headphones. See open-back vs closed-back headphones and what are reference headphones for why this matters, and studio monitors vs headphones for mixing for the bigger picture.
Build and comfort
The MDR-7506 is light and easy to wear for hours, which suits long tracking days, though its pads and coiled cable are showing their age in design terms and the cable is fixed — if it fails, you replace the headphone or re-cable it. The M50x is heavier and more heavily padded, feeling more substantial, with a firmer clamp some find tighter at first. Both fold up for transport and have a long track record of durability.
Cables and accessories
A practical win for the M50x: it ships with detachable cables, including straight and coiled options, so a damaged cable is a cheap swap rather than a repair. The MDR-7506 uses a fixed coiled cable terminating in a gold mini-jack with a screw-on adapter — reliable, but not user-replaceable without modification. If long-term serviceability matters to you, the M50x’s detachable system is the safer bet.
Which should you choose?
Choose the Sony MDR-7506 if you want a light, analytical headphone that exposes detail and flaws — ideal for tracking, editing, and quality control, and a long-standing studio standard.
Choose the Audio-Technica ATH-M50x if you want a fuller, more enjoyable sound, a more robust build, and the convenience of detachable cables, while still getting solid closed-back isolation for tracking.
For pure recording duties either is a safe, proven choice. If you do most of your serious mixing decisions on headphones, pair whichever you pick with a flatter reference set and always confirm on speakers. Explore more in the studio monitors and headphones hub.
Frequently asked questions
Are the MDR-7506 or M50x better for mixing?
Neither is perfectly flat. The 7506 is brighter and more revealing of detail; the M50x has stronger bass. Use them to catch detail, but cross-check important mix decisions on monitors or reference headphones.
Do either leak sound while recording?
Both are closed-back and isolate well, so little of the backing mix bleeds into a nearby microphone. That makes both good choices for tracking vocals and acoustic instruments.
Which is more comfortable for long sessions?
The MDR-7506 is lighter, which many prefer for all-day tracking. The M50x is heavier and more padded with a firmer clamp, feeling more substantial but tighter for some users. Comfort is personal, so try them if you can.
