Best sound cards to get rid of white noise: 7 quiet picks (2026)

If your headphones hiss or your speakers buzz, the cause may be the motherboard’s audio section. This guide covers the best sound cards to get rid of white noise, seven internal cards and USB devices, using the signal-to-noise figures in the brand pages and Amazon listings that we checked on Nov 11, 2026.

Quick verdict on the best sound cards to get rid of white noise

No sound card can promise silence, and the noise you hear may come from a cable, a ground loop or the headphones themselves. Still, moving conversion to a separate card or an external USB device is the usual fix. Our picks range from a $9 adapter to a premium internal card.

• Best low-cost internal card: Creative Sound Blaster Z SE, approx. $75.95 on Amazon (Nov 11, 2026)
• Best premium internal card: Creative Sound Blaster AE-7, approx. $229.99 on Amazon (Nov 11, 2026)
• Best external gaming DAC: Creative Sound BlasterX G6, price not in our data
• Best stereo DAC without a mic: Topping D10s, price not in our data
• Best desktop DAC and amp under $100: Fosi Audio Q4, approx. $69.99 on Amazon (Nov 11, 2026)
• Cheapest fix to try first: Sabrent USB Audio Adapter AU-MMSA, approx. $8.99 on Amazon (Nov 11, 2026)
• Best-reviewed budget adapter: Plugable USB Audio Adapter, approx. $12.95 on Amazon (Nov 11, 2026)

Why decibel figures are only a rough guide

Signal-to-noise numbers from different makers are not directly comparable, because some are A-weighted and some are not, and some measure only the converter. The gap between 120 dB and 129 dB is not something you will hear, so use the figures to separate budget from better designs.

Quick comparison table

The table lists the signal-to-noise or dynamic range figure that each source states, along with the connection type and the price. The numbers come from different measurement methods, so read them as rough categories rather than a strict ranking from best to worst.

How we selected these devices

We did not measure noise ourselves, so we cannot say how any of these will sound in your PC. We pulled the stated figures from Creative’s pages, retailer notes and Amazon listings captured on Nov 11, 2026 and kept only products that list a clear audio output.

We left out streaming mixers and voice changers, which are built for effects rather than clean playback. Amazon ratings are shopper opinions, not our scores, and we do not rank by commissions.

Where a figure came from a retailer snippet instead of the maker, we mark it as weaker evidence and suggest checking the official page.

Best sound cards to get rid of white noise in detail

Each section below describes what the device offers, the figure it publishes and what to check before you buy. Treat noise claims as marketing numbers rather than guarantees, and keep your return window handy so you can test the fix at home with your own headphones and speakers.

Creative Sound Blaster Z SE: best low-cost internal card

The Z SE is the entry point if you want a separate card inside the case rather than a box on the desk. Amazon lists it at approx. $75.95 on Amazon (Nov 11, 2026) with 4.3 stars from about 993 ratings, and Creative publishes a 116 dB signal-to-noise ratio for it.

It is a PCIe x1 card with three 3.5 mm speaker jacks, TOSLINK in and out, an amplified headphone jack that drives headphones up to 600 ohm, and Windows 8, 10 and 11 support. Creative’s page showed Notify Me when we looked, so confirm availability first.

Internal cards sit inside the case, so a poorly shielded PC can still pick up interference.

• Buy if: you want an internal card at a modest price.
• Skip if: your PC is crowded or you suspect case interference.

Creative Sound Blaster AE-7: best premium internal card

The AE-7 splits the sensitive analog stage into an external control module, which Creative pairs with a Xamp headphone amplifier. It suits listeners with demanding, high-impedance headphones who want the highest-spec internal option in this guide and are willing to pay a premium for the module.

Creative lists a 127 dB DAC dynamic range, 0.0001 percent THD+N, 1 ohm output impedance and support for headphones from 16 to 600 ohm. Amazon lists it at approx. $229.99 on Amazon (Nov 11, 2026), with 4.4 stars from about 759 ratings. It is Windows only.

One review in our notes warned that very sensitive in-ear monitors may not suit it, so check your headphones.

• Buy if: you have demanding or high-impedance headphones.
• Skip if: you own very sensitive in-ear monitors.

Creative Sound BlasterX G6: best external gaming DAC

The G6 moves the conversion outside the case, which can help if the noise comes from the motherboard area or from the power and graphics hardware nearby. Creative lists a 130 dB DAC dynamic range, a 114 dB ADC, a Xamp amplifier and bus power from USB, and it works with Windows and Mac.

We have no Amazon price for the G6, and Creative’s category page showed it out of stock. If you can find it, the USB-C connection means one cable to the PC, which also suits laptops. Remember that external devices can still pass along noise from a dirty USB port.

Consider an inline isolator only if you hear a buzz that changes with the mouse.

• Buy if: you want an external DAC with a mic jack.
• Skip if: you cannot confirm availability.

Topping D10s: best stereo DAC without a mic

The D10s is a plain playback DAC with no microphone input, which keeps it simple. Retailer pages in our notes list an ESS ES9038Q2M chip, 120 dB dynamic range, RCA analog output and USB bus power, though Topping’s own page returned an error, so treat the details as unconfirmed.

It has no headphone amplifier, so you need powered speakers or a separate amp. Optical and coaxial outputs are also listed. We do not have an Amazon price for it, and driver support outside Windows is unconfirmed.

Pick it if you feed active speakers and only want clean stereo from the PC.

• Buy if: you play music into powered speakers or a separate amp.
• Skip if: you need a headphone output or a mic.

Fosi Audio Q4: best desktop DAC and amp under $100

The Q4 combines a DAC with a headphone amplifier and accepts optical, coaxial and USB inputs. Amazon lists it at approx. $69.99 on Amazon (Nov 11, 2026), with 4.4 stars from about 3,374 ratings, a large sample for a desktop DAC, and a sign that plenty of buyers have already tried it on their own PCs.

The listing does not state a signal-to-noise figure in our data, so we cannot rank it against the others on numbers. It does give you a physical box on the desk, with a headphone output that does not depend on the motherboard.

The listing does not mention a microphone input, so you would still use onboard or USB audio for voice chat.

• Buy if: you want a headphone amp and DAC on the desk.
• Skip if: you need a mic input.

Sabrent USB Audio Adapter AU-MMSA: cheapest fix to try first

If you only suspect the motherboard, a $9 USB adapter is the lowest-risk test. Amazon shows 4.3 stars from about 40,565 ratings and approx. $8.99 on Amazon (Nov 11, 2026), by far the largest crowd of reviewers in this guide, so the rating is unusually well supported.

The listing describes a no-driver plug-and-play adapter for Windows with a 98 dB signal-to-noise ratio and 48 kHz maximum. It is stereo only and has no headphone amplifier worth the name, so it will not drive hard-to-drive headphones.

If the hiss disappears with this adapter, you have found the cause and can decide whether a better device is worth the money.

• Buy if: you want a low-cost test.
• Skip if: you need a strong headphone amp.

Plugable USB Audio Adapter: best-reviewed budget adapter

Plugable’s adapter adds 3.5 mm speaker and mic ports to computers that lack them. It has 4.4 stars from about 5,310 ratings on Amazon and costs approx. $12.95 on Amazon (Nov 11, 2026), which makes it a sensible alternative to the Sabrent unit, particularly for a second computer or a laptop that lacks a proper jack.

The listing shows two channels, a 48 kHz maximum, a 95 dB signal-to-noise ratio and support for Linux, Mac and Windows. That wider platform list is the main reason to pick it over the Sabrent adapter if you do not run Windows.

Its noise figure is slightly lower on paper, but the difference is small.

• Buy if: you want a cheap adapter that works on Mac and Linux.
• Skip if: you need an amp for demanding headphones.

Buying guide for a quieter PC

Fixing noise starts with finding where it comes from. Spend a few minutes on the checks below before you buy anything, because a new card cannot fix a loose cable or a bad ground, and you may avoid paying for a solution to the wrong problem entirely.

Find the source of the hiss

Unplug the headphones from the case and listen to a different device. If the hiss persists on the other device, the headphones are the cause. If it only appears on the PC, change the USB port or try a front panel versus rear panel jack to see whether it moves.

Noise that rises with GPU load or mouse motion points to electrical interference inside the case.

Internal card, USB DAC or adapter

Internal cards sit near the graphics card and power supply, so they can pick up interference, while USB devices sit outside the case. The Z SE and AE-7 are internal, the G6, D10s and Q4 are external desktop devices and the Sabrent and Plugable units are tiny adapters.

External devices are also easier to return and move between computers.

How to pick the best sound cards to get rid of white noise

Try the cheapest adapter first. If the noise disappears, you have shown that the onboard output is the problem. If you need a headphone amp, move to the Fosi Q4 or an external gaming DAC. Choose an internal card only if you want surround features too, since that is where they shine.

Remember the numbers are not equal across brands, so judge by your own ears.

FAQ

These answers cover what people ask when they hear white noise or hiss from a PC. They rest on the figures and notes above and avoid promises about silence, because the result depends on your headphones, your cables and your electrical setup at home.

Will a sound card remove white noise completely?

Not always. A sound card or DAC can help if the noise comes from the motherboard audio section, but it will not change noise from headphones, cables or a recording. It also cannot remove noise baked into a microphone signal. Test with a cheap adapter first.

Is an external DAC better than an internal sound card for noise?

It can be, because an external device sits away from the power supply and graphics card inside the case. The advantage is not guaranteed, though. A well-shielded internal card may be quiet in a tidy case, so the right choice depends on your PC and your tolerance for noise.

Do higher decibel numbers mean a quieter card?

Only roughly. Makers measure signal-to-noise and dynamic range in different ways, so 129 dB on one card and 120 dB on another are not directly comparable. Differences above about 100 dB are very hard to hear in practice, so choose on features, fit and price instead.

Conclusion

Start with the Sabrent AU-MMSA or Plugable adapter to find out whether onboard audio is the culprit. If it is, choose the Fosi Audio Q4 for a desktop headphone setup, the Creative Z SE for an affordable internal card, or the AE-7 if you want the highest-spec internal option.
