Who this setup is for

People comparing edits and mixes

If you switch between recording versions, a repeatable playback setting and controllable volume matter more than leaving bass or spatial effects active without noticing.

People using demanding wired headphones

If your current source struggles to provide a usable listening level, check output specifications against your headphones’ impedance, sensitivity and connector before choosing an amplifier.

People who also record at their desk

If comparison work involves microphones, instruments or different feeds for headphones and speakers, an audio interface may meet needs that a playback-only amplifier cannot. Headphone leakage still needs attention around colleagues.

What to check before buying

Analogue headphone amplifier

Choose it when: You already have a suitable line-level output and need to drive your wired headphones.

Trade-off: It does not provide digital-to-analogue conversion or recording inputs; switch optional sound modes off for a comparison baseline.

DAC/headphone amplifier

Choose it when: Your computer is the playback source and you want conversion and headphone output in one desk unit.

Trade-off: Check its output and connector against your headphones; a playback DAC/amp does not replace recording inputs.

USB audio interface

Choose it when: You also need to record sources or route different mixes to headphones and line outputs.

Trade-off: Check the interface’s headphone output for your exact headphones rather than assuming its recording features settle that question.

Concern What to check Who this matters to
Consistent playback Identify any active EQ, crossfeed, bass or spatial modes, and keep a known baseline setting when comparing recordings. If I switch between edits, I need to know that a sound mode has not changed between listens. Around 33% of consumers put a repeatable comparison baseline first.
Headphone drive and connection Match the exact headphone model’s impedance, sensitivity and connector to output specifications at the relevant load. When my existing headphones are difficult to drive, I need usable level control without assuming that a balanced socket fits my cable. For around 20% of consumers, headphone compatibility is the primary concern.
Sound around colleagues Consider whether a closed-back headphone is needed, keep listening levels controlled and follow workplace requirements for awareness and communication. I need to compare recordings without the headphones disturbing nearby colleagues. Keeping sound contained comes first for around 27% of consumers.
Recording and routing List the inputs you need and whether headphones and speakers require different mixes. If I also record at my desk, I need connections and monitoring routes that a standalone amplifier cannot provide. Around 20% of consumers prioritise that workflow.

Mistakes that affect comparisons

  • Expecting amplifier power to stop headphone leakage

    More available output does not contain sound from an open-back headphone. Sennheiser describes its closed-back headphones as designed to keep music in and outside noise out.

    Consider the headphone enclosure and a controlled listening level before choosing the device that drives it.

  • Leaving enhancement modes on during comparisons

    Bass, EQ, crossfeed and spatial settings can alter what you hear, making an unlabelled comparison setting difficult to repeat.

    Note a baseline with processing off, and use other settings only when deliberately checking an alternative presentation.

  • Buying an amplifier for a recording workflow

    An analogue headphone amplifier does not add microphone or instrument inputs. An interface such as Focusrite’s Scarlett 4i4 4th Gen can provide recording connections and separate headphone and line-output mixes.

    Write down the sources you need to connect and the mixes you need before deciding whether playback-only hardware is sufficient.

  • Treating one power figure as universal compatibility

    Headphone output figures depend on the stated load, while the socket and cable must also match. A high-gain setting can produce an uncomfortably high level.

    Compare specifications for your exact headphones and start at the lowest suitable gain setting.

Brands and product lines to consider

RME

The ADI-2 DAC FS is a DAC and headphone-monitoring option for a desk setup where configurable playback is useful.

  • RME lists dedicated headphone and IEM outputs, output-level control and processing options including EQ and crossfeed.
  • For a consistent recording comparison, establish which processing settings are active and keep a repeatable baseline.

iFi audio

The ZEN CAN 3 represents an analogue amplifier route; the ZEN DAC 3 combines USB-C digital input with headphone playback.

  • The two models offer different ways to build a playback chain, depending on whether you already have a suitable analogue source.
  • iFi offers optional sound modes on its products. Check their settings before using either model as part of a comparison baseline.

Focusrite

The Scarlett 4i4 4th Gen is a USB audio interface for desks where comparing playback overlaps with recording or monitor routing.

  • Focusrite states that its headphone and line outputs can receive separate mixes.
  • Focusrite specifies headphone output power of 57 mW into 33 ohms and 27 mW into 300 ohms for the Scarlett 4i4; assess those load-specific figures against your headphones.

Common questions

Do I need an amplifier, a DAC/amp or an audio interface?

Choose an analogue headphone amplifier if you already have a suitable line-level source and need more headphone drive. A DAC/amp combines conversion and headphone playback for a computer source; an audio interface is the route to consider if you also need recording inputs or separate monitoring mixes. Check the chosen device’s output against your headphones in every case.

Will a more powerful amplifier stop colleagues hearing my headphones?

No: amplifier output does not prevent acoustic leakage. Consider the headphone enclosure and listening level; Sennheiser describes closed-back headphones as intended to keep music in and outside noise out.

Where should I set the gain for a comparison session?

Start at a low gain setting and increase it only if your headphones need it for a usable listening level. iFi’s ZEN CAN guidance says to begin at 0 dB gain; also check that any sound-altering modes are in the intended state before comparing recordings.

Should I check for UKCA or CE marking in Great Britain?

Check the applicable product-conformity information for the device you are buying. GOV.UK guidance dated 31 March 2026 says Great Britain continues to recognise CE marking alongside or in place of UKCA marking where the relevant product regulations apply. That guidance covers England, Scotland and Wales; processes differ in Northern Ireland.
