If you want a closed-back studio workhorse you can trust for tracking, editing and critical listening, choose Shure SRH840; if you need an open-back planar-magnetic headphone with a huge, airy soundstage for long home listening sessions, choose FiiO FT1.
• Shure SRH840 — biggest strength: A closed-back, circumaural monitoring design with a precisely tailored frequency response (rich bass, clear mids, extended highs) and a 5 Hz–25 kHz range that's purpose-built for studio work.
• Shure SRH840 — biggest trade-off: Closed-back isolation means a narrower, more "inside your head" presentation than an open-back design, and it leans on a coiled detachable cable rather than the open, spacious feel some listeners prefer.
• FiiO FT1 — biggest strength: An open-back planar-magnetic driver with a 20 Hz–40 kHz range and an in-house 95x86mm flat unit that FiiO says delivers an exceptionally wide lateral soundstage.
• FiiO FT1 — biggest trade-off: Open-back means no meaningful noise isolation, so it's a poor fit for noisy rooms or tracking; it's also the heavier of the two at roughly 1.04 kg.
• Who each is for: Shure SRH840 for engineers, musicians and anyone who needs isolation and durability; FiiO FT1 for home listeners and studio users who want an expansive, detailed open-back presentation.
The SRH840 is unapologetically a monitoring tool. Shure designed it for professional audio engineers and musicians, and the spec sheet backs that up: a closed-back, circumaural, collapsible design with 40mm neodymium dynamic drivers, a 40-ohm impedance and a frequency range of 5 Hz to 25 kHz. That combination — closed cups plus a tailored response — is what you want when you need to hear what's actually in the recording without the room bleeding in, and when you need the headphones to fold up and travel.
What it does best is isolation and longevity. The closed-back circumaural fit is built to keep outside sound out and your mix in, which matters for tracking vocals or checking a take in a room that isn't acoustically perfect. The thoughtful part is the ownership experience: the cable is detachable and coiled, and Shure includes a spare set of ear pads, a carrying bag and a threaded 1/4-inch gold-plated adapter. Replaceable wear parts mean the headphone isn't disposable the moment a cable or pad gives out. The stainless-steel enclosure material also signals a build meant to survive real studio use.
Who should buy it: recording engineers, musicians, podcasters and anyone doing critical listening or editing who needs isolation, a collapsible form factor and a cable they can swap. Who should skip it: listeners chasing the widest possible soundstage or an open, room-filling presentation — the closed-back design simply won't give you that — and anyone who dislikes a coiled cable's weight and pull. If you want a set you can rely on for work rather than a set that flatters every track, this is the more sensible pick.
The FiiO FT1 (FT1 Pro) is the opposite philosophy: open-back, planar-magnetic, and aimed squarely at immersive, detailed home listening. The headline is the driver. FiiO developed a 95x86mm flat unit in-house — a size it compares to flagship heavy-duty flat earphones — and pairs it with a 1μm ultra-thin PET diaphragm. FiiO's own explanation is that even a 2μm-to-1μm thickness difference changes how the diaphragm behaves under high-speed vibration, so that thinness is the whole point of the design. The stated result is an exceptionally wide lateral soundstage with near-imperceptible boundaries and a frequency response up to 40 kHz.
The engineering story continues with the diaphragm coating and magnet design. FiiO uses a sapphire-plus-aluminum dual coating: the sapphire is there for high-frequency resolution thanks to its hardness, while the lightweight aluminum improves the voice coil's conductivity. The magnet array is arranged for a more uniform magnetic field, which FiiO says keeps diaphragm amplitude even, reduces segmented vibration and lowers distortion — the practical payoff being better capture of subtle detail. All of this is produced with a 28-nanometer chip-level coating process borrowed from semiconductor manufacturing, applied twice per diaphragm, which FiiO credits with strengthening the conductive coils' durability. The specs line up with the intent: 20-ohm impedance, planar-magnetic driver, 20 Hz–40 kHz, over-ear fit, wired 3.5mm.
Who should buy it: home listeners, mixing or mastering users who work in a quiet room, and anyone who values a wide, open presentation and fine detail over isolation. Who should skip it: anyone who needs to block out noise, record with a mic live in the room, or commute — open-back headphones leak sound both ways, and there's no noise control here at all. It's also the heavier option, and it's wired with a remote control method rather than onboard volume.
Side-by-Side: Which Should You Choose?
• Best for isolation and studio tracking → Shure SRH840. Closed-back circumaural design keeps the room out and your sound in.
• Best for durability and long-term ownership → Shure SRH840. Detachable coiled cable, included replacement ear pads, stainless-steel enclosure and a 2-year manufacturer warranty versus FiiO's 1-year.
• Best for extended high-frequency detail → FiiO FT1. Its range reaches 40 kHz with a sapphire-coated 1μm diaphragm tuned for high-frequency resolution.
• Best for plug-and-play simplicity → Shure SRH840. Both are wired 3.5mm, but Shure includes the 1/4-inch adapter, bag and spare pads in the box.
• Best for quiet-room, long-session listening → FiiO FT1. Open-back over-ear comfort with a planar driver made for immersive detail, provided your room is quiet.
• Best for traveling or noisy environments → Shure SRH840. Collapsible, closed, and isolation-focused; the FT1 is the wrong tool there.
• Best low-impedance pairing → FiiO FT1. At 20 ohms it's the easier load; the SRH840 sits at 40 ohms.
In my opinion, the Shure SRH840 is the safer buy for most people reading this, because it works in more situations: closed-back isolation, a collapsible frame, a detachable coiled cable, spare pads in the box and a 2-year warranty make it a headphone you can use for recording, editing and general listening without worrying about your environment. I'd pick the FiiO FT1 only if your priority is a wide, open planar-magnetic presentation and you always listen in a quiet room — and if that's you, the FT1's 1μm diaphragm and 40 kHz extension are genuinely appealing. Otherwise, the SRH840 is the one I'd reach for. Check the current price on Amazon before deciding, since the value math can shift.
For tracking and editing, yes — the SRH840 is closed-back with isolation, while the FT1 is open-back and leaks sound. If your studio work involves microphones in the room, the Shure is the practical choice.
They're tuned for different jobs rather than one being universally better. The FT1's planar-magnetic driver and 40 kHz range favor width and high-frequency detail in a quiet room; the SRH840's tailored response favors accurate, isolated monitoring.
The FT1 is the heavier headphone at roughly 1.04 kg, while the SRH840 is listed at 1.8 pounds with a circumaural fit. Weight and pad design matter more than specs here, so try both if you can.
Both are wired 3.5mm headphones with low impedance — 20 ohms for the FT1 and 40 ohms for the SRH840 — so neither demands a powerful amp. A dedicated amp may still help, but it isn't required to get them working.
