If you want a straightforward wired studio headphone for home recording and call center listening, choose Shure SRH440; if you need a more monitoring-focused sound and included replacement ear pads, choose Shure SRH840. Both are closed-back, collapsible designs with detachable coiled cables, but the SRH840 is shaped more explicitly around critical listening.
Shure SRH440 vs Shure SRH840 at a Glance
• Shure SRH440 strength: a closed-back, collapsible wired design for home and studio recording, with a detachable coiled cable. Trade-off: its supplied contents do not include replacement ear pads.
• Shure SRH840 strength: a monitoring-focused response, a stated 40 mm dynamic driver, and replacement ear pads in the box. Trade-off: it weighs 1.8 pounds, compared with 1.6 pounds for the SRH440.
• Shure SRH440 audio range: 10 Hz to 22 kHz. Shure SRH840 audio range: 5 Hz to 25 kHz; those figures describe their stated frequency ranges, not a guarantee of a particular listening experience.
• Both models: closed-back, circumaural and collapsible, with detachable coiled cables and sound isolation listed as a noise-control feature.
• For a simpler recording-focused pick: consider the SRH440. For critical listening and the extra included ear pads: consider the SRH840.
The SRH440 is described as optimized for home and studio recording. Its closed-back, around-ear design is intended to sit around the ears, while the collapsible construction can make it easier to put away between sessions. Sound isolation is listed among its features, which is relevant when you want to focus on recorded audio rather than an open listening setup.
Its stated frequency range is 10 Hz to 22 kHz, and Shure describes its response as delivering accurate audio across an extended range. For someone choosing headphones for a call center, that makes it a wired option to consider if listening clarity and a recording-oriented design matter more than Bluetooth or a microphone. The listed features do not specify a built-in microphone, Bluetooth connectivity, or call controls, so I would not assume it provides those functions.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-21 · 7 min read · Independent comparison
The detachable coiled cable is a practical part of the package: it can be removed from the headphones, and its coiled form is distinct from a straight cable. The SRH440 also comes with a threaded 1/4-inch gold-plated adapter and a carrying bag. The listed connection is wired, with a 6.35 mm jack, so check that your intended audio equipment can connect to it.
Who should skip it: Skip the SRH440 if you specifically want replacement ear pads included, a wireless headset, or a listed built-in microphone.
The SRH840 is aimed at studio recording and critical listening, with Shure describing its tuning as balancing bass, mid-range and extended highs. Its stated frequency range is 5 Hz to 25 kHz, broader on paper than the SRH440’s 10 Hz to 22 kHz. That difference may interest someone comparing the specifications, but the range alone does not establish how either headphone will sound to a particular listener.
For monitoring work, the SRH840’s stated 40 mm neodymium dynamic drivers and 40-ohm impedance give more detail about its hardware than the SRH440 sheet provides. Those specifications help identify the design, but they do not by themselves promise compatibility with every device or a specific level of loudness. The product is wired, has a detachable coiled cable, and includes a threaded 1/4-inch adapter and a carrying bag.
One concrete difference is the included set of replacement ear pads. That gives the SRH840 owner an extra set in the package, rather than requiring a separate purchase if a replacement is wanted later. The trade-off is its stated 1.8-pound weight, versus 1.6 pounds for the SRH440. Both numbers are product weights, not a guarantee of how comfortable a particular person will find the headphones over a long shift.
Who should skip it: Skip the SRH840 if you want a lighter listed product weight, wireless connectivity, or a built-in microphone specified for calls.
• Best fit for home and studio recording → Shure SRH440. Its stated purpose is recording, and its design combines closed-back ear coverage with a collapsible frame.
• Best fit for critical listening and monitoring → Shure SRH840. Its description directly emphasizes studio monitoring and critical listening, with a response tailored across bass, mid-range and highs.
• Best if included replacement ear pads matter → Shure SRH840. It comes with a replacement set; the SRH440’s listed package does not mention one.
• Best if you prefer the lower listed weight → Shure SRH440. It is listed at 1.6 pounds, compared with 1.8 pounds for the SRH840.
• Best if the stated frequency range is your deciding spec → Shure SRH840. Its listed range is 5 Hz to 25 kHz, while the SRH440 is listed at 10 Hz to 22 kHz. Treat this as a specification comparison, not a promise of audible superiority.
• Best for a call center when wired listening is the priority → either, depending on your fit. Both are wired, closed-back designs with sound isolation listed. Neither product sheet specifies a built-in microphone or wireless calling features.
• Best for a 6.35 mm connection listed directly → Shure SRH440. The SRH440 sheet gives a 6.35 mm headphone jack; the SRH840 sheet lists a 3.5 mm jack. Both include a threaded 1/4-inch adapter, so verify the connection you need before choosing.
• Best for someone comparing “hi res head phones for call center” → neither on that phrase alone. The sheets give frequency ranges, but do not describe either model as hi-res certified. Choose based on the stated monitoring purpose, connection and included accessories instead.
A call center shopper may start by searching for the best earphones for call center work, but these are over-ear wired headphones, not wireless earbuds. More importantly, the product information supplied for both models does not list a microphone. If your job requires two-way calls through a headset, confirm that your setup provides a separate microphone or choose a product that explicitly includes one.
The same caution applies to searches for the best IPX7 waterproof Bluetooth headphones for call center use. Neither Shure model is described here as Bluetooth-enabled or IPX7 waterproof. Both are wired, and neither sheet gives a waterproof rating. If wireless movement or water protection is essential, these specifications do not support treating either as a match.
For a desk-based setup, compare the connection details with the equipment you plan to use. The SRH440 lists a 6.35 mm jack, and the SRH840 lists a 3.5 mm jack; both packages include a threaded 1/4-inch adapter. The detachable coiled cable is common to both, as are the closed-back, collapsible design and sound isolation listing. Those shared features make the choice less about basic construction and more about intended use, stated weight and package contents.
Finally, don’t choose solely by the wider frequency-range number. The SRH840’s range extends farther at both ends on paper, while the SRH440 is explicitly described as delivering accurate audio across an extended range. Neither figure tells you everything about tonal preference, comfort over a full shift, or how the headphones will work with your equipment.

I would choose the Shure SRH840 for critical listening because its monitoring focus is explicit, and the included replacement ear pads add a useful extra. For a call center, though, I would first confirm how calls will be picked up: neither sheet specifies a built-in microphone. If you want the lighter listed weight and a recording-oriented option, I’d choose the SRH440 instead.
No. Both are listed as wired headphones and have detachable coiled cables. Neither product sheet specifies Bluetooth connectivity.
Neither is listed with a built-in microphone, so neither sheet establishes it as a complete calling headset. For listening at a desk, both offer closed-back circumaural designs and list sound isolation; confirm your microphone and connection needs separately.
Is the SRH840 worth choosing for its wider frequency range?
Its stated range is 5 Hz to 25 kHz, compared with 10 Hz to 22 kHz for the SRH440. That is a difference in specifications, not proof that every listener will hear the SRH840 as better.
The SRH840 includes replacement ear pads in its listed package. The SRH440 package lists a carrying bag, a threaded 1/4-inch adapter and a user guide, but not replacement pads.
