The best measurement microphones, compared.
Top pick: Behringer ECM8000 Best value: Behringer ECM8000 – Lowest price that still scores at least 75 with at least 200 reviews: about £16.90, phantom stated, generic file only. Updated October 2026.
A measurement microphone is a small omnidirectional electret or pre-polarised condenser, often about 6 mm, sold to report a sound field for room correction, a real-time analyser, or a processor that expects a measurement input. It is a poor substitute for a Class 2 sound level meter when the job is a noise-at-work assessment. You choose by the host you already own: a laptop with no interface, an interface that can supply phantom power, or a phone that still has a headset jack. You tell a suitable one by the connector, the power the listing states, and whether the calibration path is an individual file or only a generic curve. A printed frequency range is not a flatness claim. A file lists frequency offsets, sometimes plus a sensitivity figure, and it is not an acoustic calibrator. Those checks are in the [measurement microphone buying guide](/hub/measuring-equipment/measurement-microphone/sub/measurement-microphone-buying-guide). Point the capsule at the speaker with a 0-degree file, or at the ceiling at ear height with a 90-degree file. A windscreen only stops air across the capsule.

Question 1 of 2
What will you plug the microphone into?
The Behringer ECM8000 is an XLR condenser at £16.90, and the amazon.co.uk line is 4.6 from 1,700 reviews, with 32 United Kingdom texts in the sample. UK buyers use it for room frequency checks, studio treatment, speaker testing, and a church-hall PA on a Behringer DEQ2496, and one buyer compared two units and reported agreement within about 0.5 dB up to 10 kHz. That 0.5 dB note is one comparison, not a certificate, and the listing's 20 Hz to 20 kHz line is a stated range rather than a flatness claim. A UK review marks the microphone down because only a generic calibration file is available for Windows apps, and another buyer kept it for time alignment rather than trusting a room response. The listing states phantom power from +15 V to +48 V and does not name a battery, so a laptop headphone socket is not the host the bullets describe. Delivery notes disagree: one UK buyer received a case, a clip, and an adapter, and another said the clip was missing. It is the low shelf price in this set when you already have phantom power and will accept a generic curve.
Pros
Cons
Best for: Someone who already owns phantom power and wants a cheap omnidirectional capsule for a rough room or PA check.
Less suitable: A laptop with no interface, or any job where the individual curve has to be in the file.
Specifications
Common questions
Does the ECM8000 need a battery?
The listing asks and the bullets do not name a battery. They state phantom power from +15 V to +48 V.
Is there an individual calibration file?
Not in the bullets. A UK review says only a generic calibration file is available for Windows apps.
What pattern do the bullets state?
Omnidirectional. The listing form-factor line says boundary and gooseneck, which does not match that pattern description.
The miniDSP UMIK-1 is a USB measurement microphone at £120, and the amazon.co.uk line is 4.6 from 1,334 reviews, with 29 United Kingdom texts in the raw sample. UK buyers use it for room correction in REW, Dirac Live, and DSP or Wiim setups, and one 2026 review describes an RTA and SPL check as straightforward once the serial file is loaded. The bullets name a unique calibration file with a sensitivity figure, plus a mini tripod, a windscreen, and a padded case, and they describe the microphone as driverless USB rather than phantom-powered. One UK buyer swapped the supplied lead for a 2 m USB-C cable because the one in the box is short, and another returned the unit because the computer setup felt too involved next to the microphone that came with the receiver. The listing frequency is 20 Hz to 20 kHz, while a UK review says the box prints 8 Hz to 20 kHz. The attribute table also says one lithium-ion battery is required, which the bullets never describe. It is the strongest laptop path in this set when you want the file and the USB plug together, and a poor fit if you need a second electrical channel on the same converter.
Pros
Cons
Best for: A laptop or Mac used for one listening seat in REW or Dirac, when you do not already own an audio interface.
Less suitable: Two-channel transfer-function work, a dbx DriveRack, or a phone that has no computer.
Specifications
Common questions
Does the UMIK-1 need phantom power?
The bullets describe USB plug and play and do not name phantom power. The same attribute table says one lithium-ion battery is required, which the bullets do not explain.
Which software do the bullets name?
Dirac Live, REW, Smaart, and other acoustic software. A UK review also used it with an Arcam AVR running Dirac.
Is a case in the box?
The listing includes a mini tripod, a USB cable, and a windscreen in a padded transport case. UK reviews say the supplied cable is short.
The dbx RTA-M is sold as the omnidirectional microphone for the DriveRack series at £105.75, and the amazon.co.uk line is 4.6 from 298 reviews. Three United Kingdom texts sit in the raw sample, and one of them is an off-topic prompt rather than a product comment. The UK lines that do address the microphone say it works with a DriveRack PA2. The listing states DC 9 V to 52 V, an XLR connector, and no cable in the box, with a clip and a case. A reviewer used one with an iPad RTA app and a Focusrite interface when no DriveRack was in the system, after a comparison against a Brüel & Kjær omnidirectional microphone. Other texts describe crackling or popping after a minute or two, a unit that failed after a week, and a microphone that arrived noisy on cables that were quiet with other capsules. No individual calibration file is stated. It is the row for a DriveRack, and a weak default if you wanted a calibrated USB microphone for a laptop.
Pros
Cons
Best for: A dbx DriveRack owner who wants the microphone the listing names for that processor.
Less suitable: A laptop measurement with no DriveRack, or anyone who needs an individual calibration file in the box.
Specifications
Common questions
Is a cable included?
No. The listing says the cable is not included. Box contents name a clip and a case.
Which processor do the bullets name?
The DriveRack series. UK reviews mention a DriveRack PA2. Recording use is asked in the FAQ and not answered in the bullets.
What voltage does the listing state?
Operating voltage DC 9 V to 52 V. That is the phantom range printed on this amazon.co.uk page.
The Dayton Audio iMM-6 is a small omnidirectional capsule on a 3.5 mm TRRS plug at £42.12, and the amazon.co.uk line is 4.5 from 1,142 reviews, with 21 United Kingdom texts in the sample. UK buyers use it for room-correction measurements and car-audio EQ on an iPad with AudioTools, or on an Android phone once the Dayton file is loaded. The title says calibrated, but the bullets do not describe that file, so the download step comes from the reviews rather than the specification table. A 2026 UK review used an older handset because the current phone is USB-C and has no analogue jack. The listing asks whether a laptop will work and the bullets do not answer yes. One unit arrived damaged and was returned before it could be tested. The frequency-response attribute stops at 18 kHz and the bullets do not state a low-frequency limit. It belongs with a phone or tablet that still has a headset jack, and it does not replace a USB microphone on a jack-less laptop.
Pros
Cons
Best for: A phone or tablet that still has a 3.5 mm TRRS headset jack, for room or car measurements in an app.
Less suitable: A current USB-C phone with no analogue jack, or a laptop you expected to plug this into.
Specifications
Common questions
Will the iMM-6 work on Android?
The listing says yes for Android devices that still have a TRRS headset jack. A 2026 UK review used an older phone because the current handset is USB-C.
Can I use it with a laptop?
The listing asks that question and the bullets do not say yes. Treat a laptop as unanswered on this page.
Is there a kickstand?
Yes. The box description includes a kickstand that elevates and angles the device and the capsule, plus a headphone or line-out pass-through.
The Dayton Audio EMM-6 is an XLR electret at £84.68, with 4.5 from 358 reviews and two United Kingdom texts in the sample. A UK review describes a boxed individual calibration graph and a serial-number download, and says the microphone compared well with others nearly five times the price. Another UK buyer returned it because the file showed deviations of 2 to 3 dB where a flat line was expected. The printed curve is the correction, and other reviewers were surprised it was not flat. The amazon.co.uk bullets do not state a phantom voltage, so you cannot read +15 V to +48 V off this listing. Self-noise is called very high in one review and able to disturb a control-room measurement. A dented XLR opening stopped the plug connecting, and that buyer would not trust the calibration afterwards. The case, the clip, and the calibration paper are the concrete extras in the box. It is the XLR row to open when you already have phantom power and you want the graph the ECM8000 does not include.
Pros
Cons
Best for: An interface that already supplies phantom power, when you want Dayton's individual graph rather than a generic curve.
Less suitable: A buyer who expects the printed response to be a flat line, or a laptop with no XLR interface.
Specifications
Common questions
Is the calibration file individual?
The bullets include a unique calibration response graph. A UK review also describes online access by serial number.
Does the listing state phantom voltage?
No. The amazon.co.uk bullets leave phantom voltage unstated. A maker sheet is a separate claim.
What is in the case?
A stand mount, a foam windscreen, a transport case, and the calibration graph. The box-contents attribute also names a warranty card.
The PreSonus PRM1 is a 1/4-inch XLR electret at £55, and the amazon.co.uk line is 4.4 from 80 reviews, with one United Kingdom text in a sample of 13. That UK line says it works well with a PA2. The box includes a clip, a foam windscreen, and a hard case, and the listing calls the response linear from 20 Hz to 20 kHz and names room correction, speaker calibration, and PreSonus StudioLive mixers with Smaart. A review states that a calibration file is not included, and treats that absence as the reason for the price. Phantom voltage is not stated in the bullets. The weight attribute prints 0.45 g, which is not a believable microphone mass, so treat that cell as a bad listing figure. One buyer disliked the quality and was disputing a refund. It sits between the ECM8000 and the EMM-6 on price, with a case and without an individual file.
Pros
Cons
Best for: A PreSonus StudioLive or a PA measurement where a hard case matters more than an individual file.
Less suitable: A buyer who needs the calibration curve in the box, or who is choosing from the UK review count alone.
Specifications
Common questions
Does the PRM1 include a calibration file?
Not in the bullets. A review says the microphone does not include a calibration file, and gives that as the reason for the price.
What comes in the box?
A clip, a foam windscreen, and a hard case.
Which mixers do the bullets recommend?
PreSonus StudioLive mixers and VSL with Smaart. The only UK review mentions a PA2.
The Superlux ECM999U is a USB-C measurement microphone at £76, and the amazon.co.uk line is 4.2 from 32 reviews. None of the 28 review texts in the saved listing are from the United Kingdom, so the comments that follow are United States texts rather than a UK sample. The bullets state 10 Hz to 20 kHz, 24-bit/48 kHz, a 133 dB maximum SPL, a 1/4-inch capsule, and a 2 m USB cable, and they say phantom power and an external interface are not required. Reviewers used it with REW and for a desktop monitor tune, and one called a side-by-side with a dearer reference very close. The same file includes a return because the calibration QR or link did not work and Amazon support did not produce the file. A taller stand than the included table stand is wanted in one review. Superlux calls the capsule free-field, which stays a maker claim on a thin, non-UK review set. It is a USB-C alternative only when the calibration slip on the outer packaging actually yields a file.
Pros
Cons
Best for: A Windows 10, Windows 11, or Mac laptop when you specifically need USB-C and the calibration slip works.
Less suitable: Anyone judging it from UK reviews, because this saved listing has none, or a two-channel measurement.
Specifications
Common questions
Does the ECM999U need an audio interface?
The bullets say it removes the need for phantom power and for an external audio interface. Systems named are Windows 10, Windows 11, and Mac.
Where is the calibration file?
The listing says details are on a slip on the outer packaging, and to contact the seller if it is missing. A US review says the promised link did not work.
Are there UK reviews in this file?
No. The raw sample has 28 texts and none are marked United Kingdom. The 4.2 from 32 is the listing line, not a UK write-up.
The beyerdynamic MM 1 is an omnidirectional condenser at £219, and the amazon.co.uk line is 4.2 from 12 reviews, with one United Kingdom text among three in the saved listing. The listing says it is linear at 90 degrees and diffuse-field calibrated, with a tolerance of ± 1.5 dB between 50 Hz and 16 kHz, and the box includes a clamp, a hard case, and an individual measuring note. The UK review used it for room calibration and monitor alignment, and says further calibration files arrived by email after a request rather than as a download in the carton. Phantom voltage is not stated on the amazon.co.uk bullets. The frequency-response attribute stops at 16 kHz, a narrower printed band than the 20 kHz lines on cheaper rows. Two of the three texts are short praise from outside the UK, so the complaint list is thin. It is a stated-tolerance XLR microphone when you will wait for the emailed files, and it is not a large-sample UK pick.
Pros
Cons
Best for: A home studio that wants the stated 90-degree tolerance and will request the files.
Less suitable: Anyone who wants a large UK review sample, or a file they can download before the first sweep.
Specifications
Common questions
Where is the calibration file?
The box includes an individual measuring note. A UK review says the 0-degree and 90-degree files have to be requested and are emailed.
What tolerance does the listing print?
± 1.5 dB between 50 Hz and 16 kHz, described as linear at 90 degrees and diffuse-field calibrated.
What clamp is in the box?
The MA-CL 21 clamp, with a 3/8 inch internal thread and a 21 mm inner diameter, plus a hard case.
The Audix TM1 is a 6 mm omnidirectional condenser at £249, and the amazon.co.uk line is 4.1 from 17 reviews. None of the four review texts in the saved listing are from the United Kingdom. A 2025 US review praises the build and the accuracy, and another says a later TM1 had less low-end roll-off than an earlier Audix reference microphone. One unit arrived defective and was replaced by Audix, with a windshield sent as a gift. The bullets describe a linear 20 Hz to 20 kHz response and do not name a calibration file or a case. Phantom voltage is not stated on the listing. The item-type attribute says dynamic microphone while the bullets say condenser, and the country-of-origin attribute says China while the bullets say the microphone is machined and tested in the United States. At the highest price in this set, both the file and the UK sample are missing.
Pros
Cons
Best for: An engineer who already knows the TM1 and is replacing a unit, with the maker's own phantom figure checked off this listing.
Less suitable: A first measurement microphone chosen because it is the dearest row, or a buyer who needs UK reviews and a file in the box.
Specifications
Common questions
Is the TM1 omnidirectional?
The bullets say omnidirectional. The item-type attribute says dynamic microphone, which contradicts the condenser description.
Does it come with a case?
The listing FAQ asks and the bullets do not answer. A US review of a replacement mentions a windshield sent as a gift, not a case in the box.
Is a calibration file named?
No. The title and bullets say accurate measurement and SPL, and they do not name a file.
Nine measurement-microphone listings on amazon.co.uk were scored on 21 October 2026 from the listing and the review notes. This is not a laboratory test, and a capsule is not scored as a Class 1 or Class 2 sound level meter. Listing cells that describe the wrong object stay in the notes and do not add points. Amazon evidence, calibration and host, the United Kingdom review pattern, and value are weighted 40, 30, 20 and 10. The top pick is the highest score. If two scores tie, the higher amazon.co.uk review count takes that place. Best value is the lowest price among microphones that score at least 75, have at least 200 reviews, and are not the top pick.
Amazon evidence
40%Up to 40 points from the amazon.co.uk star average and how many reviews sit behind it. A count of at least 1,000 scores higher than a count under 15. The block is capped at 40. Stars are not a calibration.
Calibration and host
30%Up to 30 points for the connector and the calibration path the listing actually prints. A unique file on USB scores higher than an individual graph, a file that appears only in reviews, a measuring note, a stated phantom range with no individual file, a USB-C file claim, a review that says no file, or no file and no United Kingdom text.
Review pattern
20%Up to 20 points from how many United Kingdom review texts are in the raw sample. At least 20 UK texts scores higher than two, one, or none. A large non-UK sample does not fill that gap.
Value
10%Up to 10 points for the shelf price against review volume. The lowest price with at least 1,000 reviews scores highest on this block. A dearer microphone with an individual file and a large count can still score. The block does not treat a generic curve as the same thing as an individual file.
Start with the connector, then the power the listing states, then whether the file is individual or generic. The notes below follow that order for these nine listings. None of the scores is a laboratory test.
A measurement microphone in this comparison is a small omnidirectional electret or pre-polarised condenser, usually about 6 mm, sold to report a sound field. UK buyers use that reading for room correction, a real-time analyser, a processor that expects a measurement input, or a phone app. It is a poor substitute for a Class 2 sound level meter when the job is a noise-at-work assessment.
The ECM8000 listing states phantom power from +15 V to +48 V and does not name a battery. A laptop headphone socket is not that supply. USB and USB-C rows are the ones that carry the converter.
Use a 0-degree file with the capsule pointed at the speaker, and a 90-degree file with the capsule pointed at the ceiling, at ear height. The two files are not interchangeable.
An individual response graph is the correction. One UK buyer returned an EMM-6 because the file was not a flat line. A flat line is not what that graph is for.
The first split is the host you already own. USB and USB-C measurement microphones carry the preamp and the converter. The bullets that describe them do not ask for phantom power, and they cannot be one channel of a two-channel transfer-function measurement, because the converter is inside the capsule. A 3.5 mm TRRS plug is neither of those. It takes power from a headset jack and usually offers a headphone pass-through. It belongs on a phone or tablet that still has that jack.
A calibration file is a list of frequency offsets, sometimes plus a sensitivity number. It is not an acoustic calibrator, and it does not make the capsule an integrating sound level meter. The UMIK-1 listing ties a unique file, including sensitivity, to the serial number. The EMM-6 listing includes an individual response graph, and a UK review also describes a serial download. The MM 1 box includes an individual measuring note.
Three typical situations, each with a recommendation from this comparison.
You want one listening seat in room-correction software and you do not already own an audio interface. The miniDSP UMIK-1 is about £120, with 4.6 from 1,334 amazon.co.uk reviews. The bullets name a unique calibration file, including sensitivity, on USB. It is a poor fit for a second channel on the same converter.
You already have an interface or mixer and a generic curve is acceptable. The Behringer ECM8000 is about £16.90, with 4.6 from 1,700 reviews. The listing states phantom power from +15 V to +48 V and does not include an individual file. A laptop headphone socket is not the host.
You measure a room or a car from a phone or tablet that still has a 3.5 mm TRRS headset jack. The Dayton Audio iMM-6 is about £42.12, with 4.5 from 1,142 reviews. A 2026 UK review used an older handset because the current phone is USB-C. It does not replace a USB microphone on a jack-less laptop.
The top pick is the miniDSP UMIK-1 at about £120. The amazon.co.uk line is 4.6 from 1,334 reviews, and the bullets name a unique calibration file, including sensitivity, on a USB plug that does not call for phantom power. Best value is the Behringer ECM8000 at about £16.90, with 4.6 from 1,700 reviews. It is the lowest price among the microphones that score at least 75 and have at least 200 reviews. The listing states phantom power from +15 V to +48 V and does not include an individual file. A 4.6 from 1,700 reviews does not outrank a serial file on USB. None of these scores is a lab test, and none of these capsules is a Class 2 sound level meter.
Behringer ECM8000
Lowest price that still scores at least 75 with at least 200 reviews: about £16.90, phantom stated, generic file only.
