If you want maximum sonic openness and a natural, wide soundstage for critical listening, choose Shure SRH1440; if you need serious passive noise isolation for tracking, travel or loud rooms, choose Direct Sound EX29.
• Shure SRH1440 — biggest strength: open-back, circumaural design with 40 mm neodymium drivers (15 Hz–27 kHz) that prioritizes a natural, spacious presentation for mastering and critical listening.
• Shure SRH1440 — biggest trade-off: open-back means it leaks sound in and out, so it is a poor choice for noisy places or anywhere you need to keep your audio private.
• Direct Sound EX29 — biggest strength: closed-back design with 36.7 dB of passive attenuation and 114 dB sensitivity, built to block the outside world and run loudly off modest sources.
• Direct Sound EX29 — biggest trade-off: the isolation-first, closed-back approach narrows the soundstage and it is heavier (1.1 lb) than the Shure.
• Who each is for: the SRH1440 suits mixing, mastering and quiet-room listening; the EX29 suits drummers, tracking engineers, commuters and anyone fighting background noise.
The SRH1440 is an open-back, circumaural headphone, and that single design choice explains almost everything about it. The open back lets air move freely behind the 40 mm neodymium drivers, which is what gives this model its exceptionally natural sound, wide stereo image and increased depth of field. Its frequency range runs from 15 Hz to 27 kHz, so it reaches deep into the bass and well past the top of human hearing. If you have ever put on a closed headphone and felt like the music was happening inside a small box, this is the opposite experience — instruments sit in space rather than on top of each other.
The build leans toward long sessions. Shure uses a fully adjustable, premium padded headband with a steel frame, and the earcups are circumaural, meaning they surround the ear rather than press on it. At 37 ohm, the impedance is optimized for direct connection to a wide range of portable audio devices, so you are not forced into a dedicated amp just to get usable volume. The cable is oxygen-free copper with a Kevlar-reinforced jacket, and the package includes a storage case, a replacement set of velour earpads and an additional cable — a thoughtful bundle for anyone who plans to keep these for years. Connections cover both 3.5 mm and 6.35 mm jacks.
Who should buy it: producers, mixers and mastering engineers working in a quiet room, plus listeners who value an open, airy presentation and comfort over hours. Who should skip it: commuters, open-office workers, anyone recording near a live microphone, and anyone who needs to block out a noisy environment. Open-back headphones physically cannot isolate, and the SRH1440 does not pretend otherwise. If your room is loud or your audio needs to stay private, this is the wrong tool.
The EX29 Plus takes the opposite approach and commits to it. It is a dynamic, closed-back headphone with a quoted passive attenuation of 36.7 dB — an unusually aggressive figure that reflects its "extreme isolation" identity. The 40 mm closed-back drivers are tuned for what Direct Sound calls High Precision Audio, with a 20 Hz–20,000 Hz frequency response, 32 ohm impedance and 114 dB sensitivity at 1 kHz / 1 mW. That sensitivity number matters in practice: high-sensitivity, low-impedance headphones tend to get loud easily from phones, laptops and small interfaces without much amplification.
The professional details are aimed at people who move around. The cable is detachable for greater mobility, and the cable grommets are aircraft-grade aluminum, which the brand ties to stability and quiet operation — a small thing that matters when a cable rubs against your collar mid-take. In the box you get an 8-foot cable extension with a 3.5 mm stereo plug and a 6.3 mm screw-on adapter, which stretches the EX29 from a portable pair to something you can run across a studio floor. The headband is a redesigned universal fit, and the enclosure is aluminum in a Midnight Black finish. Weight is listed at 1.1 lb, noticeably more than the Shure, though that mass is part of how a closed, isolating headphone seals.
Who should buy it: drummers and tracking musicians who need to play along to a click without bleed, engineers cutting vocals in the same room as a live mic, commuters, and anyone working in loud or unpredictable environments. Who should skip it: critical listeners who want the widest possible soundstage and the most natural open presentation. A closed, heavily isolating design narrows the sense of space by nature, and the EX29 is unapologetically built around that trade.
Side-by-Side: Which Should You Choose?
• Best for a wide, natural soundstage → Shure SRH1440. Open-back, circumaural design with increased depth of field.
• Best for blocking outside noise → Direct Sound EX29. 36.7 dB of passive attenuation versus essentially none on the open-back Shure.
• Best for mixing and mastering in a quiet room → Shure SRH1440. Full-range 15 Hz–27 kHz response tuned for detailed highs and rich, controlled bass.
• Best for loud playback from weak sources → Direct Sound EX29. 114 dB sensitivity and 32 ohm impedance make it easy to drive.
• Best for long-session comfort → Shure SRH1440. Padded adjustable headband, steel frame and a lighter 0.34 kg build.
• Best for cable flexibility and reach → Direct Sound EX29. Detachable cable plus an 8-foot extension and screw-on 6.3 mm adapter.
• Best for long-term ownership extras → Shure SRH1440. Includes a storage case, spare velour earpads and an extra cable, backed by a 2-year warranty versus 1 year on the EX29.
In my opinion, the right pick comes down to your room, not the spec sheet. If you work in a quiet space and your priority is hearing what is actually in the mix — depth, air, separation — I would buy the Shure SRH1440. If you record, play drums, commute, or share a noisy space, I would buy the Direct Sound EX29 without hesitation, because no amount of tuning fixes a headphone that cannot keep the world out. Buy for the environment you actually work in, and check the current price on Amazon before you commit.
For mixing and mastering in a quiet room, yes — in my opinion. The open-back SRH1440 gives a wider stereo image and more natural depth, with a 15 Hz–27 kHz range. In a noisy room, though, that advantage disappears because you cannot hear the low end over the background.
It is rated for 36.7 dB of passive attenuation, which is a genuinely high figure for a headphone without active electronics. In practice that means it can meaningfully cut drums, engine noise and room chatter. Expect isolation, not silence.
The EX29, on paper. It lists 32 ohm impedance and 114 dB sensitivity, so it reaches high volume from modest sources. The SRH1440 sits at 37 ohm and is described as optimized for portable devices, so it is also easy to drive, just not quite as efficient as the EX29.
No. The EX29 Plus has a detachable premium cable and ships with an 8-foot extension plus a 6.3 mm screw-on adapter. The SRH1440 uses a fixed oxygen-free copper cable with a Kevlar-reinforced jacket, and Shure includes a spare cable and replacement velour earpads instead.
