The retained reference is $169 current U.S. price. The A revision is retained; original SRH840, SRH440A, SRH1540, communication-cable bundles and used units are different systems. Confirm seal, clamp, channel match, leakage, clean drive, parts, warranty and return terms before payment.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.

SRH840A is the defended mid-price closed monitor when a detachable cable, supported pads and controlled all-purpose studio balance matter more than open staging, ultralight weight or several included cable lengths.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
SRH840A was checked against manufacturer identity, exact current U.S. price, specification or manual, U.S. support, independent measurements or professional editorial and bounded exact-model owner evidence.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner evidence is retained as a fit, pad, seal, leakage, cable, drive and service checklist for SRH840A, not a sound, translation, comfort, defect or hearing-safety rate.
Reports are self-selected and span unlike heads, glasses, pads, listening levels, interfaces, amplifiers, rooms, production lots and service regions. They cannot establish population response, comfort, channel matching, reliability, mix translation, isolation or hearing safety.Self-selected exact-model owners discuss fit, clamp, eyeglass seal, pad wear, tonal change, isolation, leakage, cable faults, driver matching, source drive and service. Reports span different heads, pads, units, levels and chains, so they define acceptance checks rather than population sound, translation, comfort or reliability rates.
Keep SRH840A revision identity explicit and price pads and cable before assuming the detachable design removes downtime

Shure identifies SRH840A as a 40-ohm closed-back dynamic headphone with 40 mm matched drivers, padded folding headband, detachable locking cable and supported replacement pads.
Sweetwater lists the current SRH840A at $169. The A revision is retained; original SRH840, SRH440A, SRH1540, communication-cable bundles and used units are different systems
Closed-back circumaural dynamic design with matched 40 mm neodymium drivers, collapsible yokes and padded headband. The A revision changes chassis and package from the original SRH840. Shure specifies 40 ohms, 97 dB/mW sensitivity and 5 Hz to 25 kHz response. Headphone-amplifier noise, current, output impedance and actual program level remain system checks. A detachable locking 3 m straight cable terminates in 3.5 mm with a threaded 6.3 mm adapter; Shure also offers a separate coiled replacement. Confirm the proprietary cup lock before using generic cables.
Shure retains a current U.S. product page, guide, two-year warranty, replacement SRH840A pads, straight and coiled cables and service portal. Verify parts inventory and repair pricing for fleet use. Padded circumaural construction targets extended sessions, while clamp, ear clearance and heat vary by wearer. Supported replacement pads change seal as they age or are renewed.
Independent measurement-led review examines response, isolation, fit and build for the A revision. Fixture seal and one unit cannot establish every wearer's balance or durability.
Self-selected exact-model owners discuss fit, clamp, eyeglass seal, pad wear, tonal change, isolation, leakage, cable faults, driver matching, source drive and service. Reports span different heads, pads, units, levels and chains, so they define acceptance checks rather than population sound, translation, comfort or reliability rates.
NIOSH explains that both sound level and exposure duration affect hearing risk. Headphone sensitivity, isolation, maximum input or amplifier headroom does not establish a safe level or duration.

Manufacturer identity, exact current U.S. price, specification or manual, support path, independent measurements or professional editorial and bounded exact-model owner evidence were checked on August 20, 2026. This desk covers current U.S.-supported wired over-ear headphones used for recording, tracking, editing, mixing or mastering across open, closed and semi-open professional or reference branches. It excludes consumer Bluetooth-first and noise-cancelling models, gaming headsets, aviation headsets, in-ear monitors, bare drivers, cosmetic editions, discontinued or used-only models and marketplace-only unsupported products. Preserve exact acoustic principle, driver and generation, impedance and whether sensitivity is stated per volt or per milliwatt, amplifier output impedance, voltage and current, clean headroom, open-back leakage, closed-back isolation basis, eyeglass and jaw seal, headband pressure, weight, ear clearance, pad material and wear, pad-dependent voicing, left-right matching, cable length, cup connector and adapter, included case or alternate pads, replacement parts, warranty, service region and repair freight. Manufacturer frequency range, sensitivity, distortion and isolation claims remain tied to their published method. Independent fixture measurements are fit- and rig-dependent, while owner reports are self-selected. No specification, price, review, target curve, calibration profile, pad, headphone, amplifier, warranty or service plan guarantees neutral sound, mix translation, mastering accuracy, recording success, comfort, isolation, reliability, hearing protection or any creative, commercial, health or safety outcome. Limit sound level and exposure duration; high sensitivity, strong isolation or available amplifier power is not a safe listening-level instruction.
