If you want maximum passive noise isolation and a rugged, purpose-built monitoring headphone for loud environments, choose Direct Sound EX29; if you need wider frequency extension, interchangeable cables and a collapsible studio monitor for critical listening, choose Audio-Technica ATH-M50x.
• Direct Sound EX29 — biggest strength: Extreme passive attenuation rated at 36.7 dB, paired with 40 mm closed-back drivers and a high 114 dB sensitivity that makes it easy to drive.
• Direct Sound EX29 — biggest trade-off: Frequency response tops out at 20,000 Hz and the design is wired-only with a fixed 3.5 mm jack approach; there's no collapsible folding mechanism mentioned.
• Audio-Technica ATH-M50x — biggest strength: 45 mm large-aperture drivers with a 15–28,000 Hz frequency response, three interchangeable cables and a collapsible frame.
• Audio-Technica ATH-M50x — biggest trade-off: Lower 99 dB sensitivity and 38 ohm impedance mean it wants a bit more clean power, and its noise isolation is described as good passive isolation rather than an extreme attenuation figure.
• Who each pick is for: EX29 for drummers, live-sound players and anyone fighting a loud room; ATH-M50x for studio tracking, mixing and everyday critical listening.
The Direct Sound EX29 is built around one idea: keep the outside world out. Its headline figure is 36.7 dB of passive attenuation from closed-back speakers. That's the kind of isolation you want when the environment around you is genuinely loud — a drum kit two feet away, a stage monitor, a loud rehearsal room, or a noisy commute where you'd rather not crank the volume to hear anything.
Beyond isolation, the EX29 covers a 20–20,000 Hz frequency response with 40 mm closed-back dynamic drivers and 32 ohm impedance. Sensitivity is rated at 114 dB at 1 kHz at 1 mW, which is high — meaning it should reach usable volume easily from a phone, laptop or interface without demanding a lot of gain. The build leans functional and durable: aluminum enclosure material, aircraft-grade aluminum cable grommets, a detachable premium cable, plus an 8-foot cable extension with a 3.5 mm stereo plug and a 6.3 mm screw-on adapter. A redesigned universal headband is there for comfort over long sessions.
Audio-Technica ATH-M50x: Who It's For
The ATH-M50x is the classic closed-back studio monitor, and the spec sheet explains why. It uses 45 mm large-aperture dynamic drivers with a 15–28,000 Hz frequency response — a notably wider range than the EX29, especially at the top end and a little at the bottom. Impedance is 38 ohm and sensitivity is 99 dB, so it's a normal-efficiency headphone that benefits from a decent source, but it doesn't need anything exotic.
What really separates it for studio work is the accessory set and flexibility. You get three interchangeable cables — a 3.9–9.8 ft coiled, a 9.8 ft straight, and a 3.9 ft straight — plus a protective carrying pouch, a 6.3 mm screw-on adapter and a desktop headphone stand in this bundle. That means one headphone can do tracking, mixing and casual listening without cable compromises. The frame is collapsible for space-saving portability, and the contoured, around-the-ear earcups with soft padding are designed for extended wear. The closed-back design provides solid passive isolation with minimal bleed — useful when you're recording a mic in the same room.
In my opinion, the M50x is the better all-rounder for anyone whose main job is listening and judging audio: mixing, editing, producing, or just enjoying music with accurate reproduction. Skip it if your absolute priority is shutting out a very loud environment — the data sheet frames its noise control as sound isolation, not an extreme attenuation rating like the EX29's 36.7 dB. Also skip it if you want the simplest possible single-cable setup; three cables are versatile, but they're also more to manage. As with any purchase, verify the current price on Amazon before deciding.
Side-by-Side: Which Should You Choose?
• Best for extreme noise isolation → Direct Sound EX29. 36.7 dB of passive attenuation is the clear differentiator, and it's the whole point of the design.
• Best for easy driveability from weak sources → Direct Sound EX29. At 114 dB sensitivity and 32 ohm, it reaches volume with less amplifier effort than the 99 dB / 38 ohm M50x.
• Best for cable flexibility → Audio-Technica ATH-M50x. Three interchangeable cables (coiled plus two straight lengths) beat a single detachable cable with an extension.
• Best for portability and storage → Audio-Technica ATH-M50x. It collapses and ships with a pouch and stand.
• Best for live performance and loud rehearsals → Direct Sound EX29. The isolation and aluminum-heavy construction suit stage and practice-room abuse.
• Best for studio mixing and critical listening → Audio-Technica ATH-M50x. The large-aperture drivers and wider response are aimed squarely at accurate reproduction.
• Best for a single do-everything headphone → Audio-Technica ATH-M50x. In my opinion it covers more ground across tracking, mixing and casual use.
If I had to buy one, I'd pick the Audio-Technica ATH-M50x. The wider 15–28,000 Hz response, 45 mm drivers, three swappable cables, collapsible frame and included stand make it the more versatile headphone for most people who split their time between studio work and everyday listening. That said, I'd genuinely recommend the Direct Sound EX29 to anyone whose problem is noise — a drummer, a live performer, or someone working in a loud room. Its 36.7 dB attenuation and high 114 dB sensitivity solve a problem the M50x only partly addresses. Match the tool to the job and you'll be happy either way.
Yes, based on the specs. The EX29 carries a 36.7 dB passive attenuation rating, while the M50x is described as offering good passive sound isolation without a comparable attenuation figure. For very loud environments, the EX29 is the stronger choice.
They're tuned for different jobs. The M50x has a wider 15–28,000 Hz frequency response and larger 45 mm drivers, which suits analytical listening. The EX29 covers 20–20,000 Hz with 40 mm drivers and focuses on isolation and easy driveability. "Better" depends on whether you value extension or isolation.
Yes. The M50x includes three interchangeable cables — a coiled 3.9–9.8 ft, a straight 9.8 ft and a straight 3.9 ft — plus an adapter, pouch and stand. The EX29 uses a detachable premium cable with an 8 ft extension and a 6.3 mm screw-on adapter.
The Direct Sound EX29, in my opinion. Its 114 dB sensitivity and 32 ohm impedance mean it needs less power to hit a given volume than the M50x at 99 dB and 38 ohm. The M50x still works fine from most devices, but benefits from a stronger source.
