For a vast majority of users these days, computers aren't just productivity-focused tools, but also entertainment-centric gadgets. They are used for listening to music, watching videos, and even playing games. Perhaps this is why a great sound card is essential for any modern-day PC. Although the basic onboard solutions found in most PCs get the job done, you need a dedicated sound card to take your computer's audio experience to the next level. It's even more important if you use your setup for specialized tasks such as competitive gaming or music production. These expansion cards usually come with features like integrated amplifiers, DACs for encoding/decoding audio, and a diverse range of I/O and connectivity options.

Choosing the right sound card for your system can be a daunting task, since there are dozens of them out there. To help you out, we've detailed some of the finest PC sound cards/amplifiers in the market. Among these are PCIe-based options (best suited for desktops) such as ASUS Essence STX II, as well as USB-powered models (ideal for laptops, and even gaming consoles) like Creative Sound BlasterX G6. Read all about them, and make an informed decision!

Best Overall: Creative Sound Blaster Z

Creative Labs Sound Blaster Z
What We Like
  • Lots of connectivity options

  • Integrated beamforming microphone

What We Don't Like
  • Annoying red LED lighting

Best Lighting: EVGA 712-P1-AN01-KR NU Audio Card

What We Like
  • Made from top-quality components

  • Passive heatsink with copper shielding

Boasting customizable 10-mode RGB lighting that reacts to audio output, this thing looks as amazing as it works.

Best Controller: Creative Sound Blaster AE-7

What We Like
  • Handy controller unit with audio ports

  • Individual amplification for each channel

What We Don't Like
  • Unintuitive software

Hands down one of the most powerful PC sound cards available out there, Creative's Sound Blaster AE-7 boasts a Signal-to-Noise Ratio (SNR) of 127dB and supports 32-bit/384kHz audio playback. There's also an integrated 600ohm headphone amplifier, working alongside the ESS SABRE-class 9018 Digital-to-Analog Converter (DAC) to output rich (5.1 channel for speakers and 7.1 channel for headphones) surround sound.

However, the card's best feature is its companion "Audio Control Module" unit, which allows you to effortlessly adjust the volume level using a convenient knob. In addition to that, it also has a built-in microphone array, two 3.5mm audio ports, and two 6.3mm audio ports for hassle-free I/O and connectivity. Speaking of which, the Sound Blaster AE-7, itself, comes with five 3.5mm audio ports and a TOSLINK port. The PCIe sound card is powered by a dedicated "Sound Core3D" audio processor, and you can adjust a wide array of settings (e.g. recording resolution, encoding format) via its companion software utility.

“If you’re tired of sound cards having hard-to-reach ports and cumbersome controls, Creative’s Sound Blaster AE-7 is just what you need.” — Rajat Sharma, Product Tester

Best External: Creative Sound BlasterX G6

What We Like
  • Works with a multitude of devices

  • Special gaming-oriented mode

What We Don't Like
  • Disappointing mic input

Even though internal sound cards work great, they are limited only to PCs because of their PCIe expansion bus interface. However, that's not an issue with Creative's Sound BlasterX G6, as it's powered via USB. This essentially means that, in addition to laptops and desktops, you can also hook it up to gaming consoles like Xbox One, PlayStation 4, and Nintendo Switch. Featuring an integrated Digital-to-Analog Converter (DAC) and a Signal-to-Noise Ratio (SNR) of 130dB, it supports 32-bit/384kHz high fidelity audio.

The external sound card also includes a discrete 600ohm headphone amplifier, which amplifies both audio channels individually. In terms of connectivity and I/O options, the Sound BlasterX G6 comes with two 3.5mm audio ports, two Optical TOSLINK ports, and a microUSB port. You get a single side-mounted dial for easily controlling both gameplay audio and mic volume, and the companion software program can be used to adjust everything from Dolby Digital effects to noise reduction settings.

Best Compact: FiiO E10K

What We Like
  • Lightweight yet premium design

  • One-click Bass boost

What We Don't Like
  • Questionable long-term reliability

Measuring around 3.14 x 1.93 x 0.82 inches and weighing just 2.75 ounces, FiiO's E10K is small enough to fit in the palm of your hand. But don't let that compact size fool you, as this thing is absolutely wonderful. It's worth mentioning here that it's not a sound card, but a portable Digital-to-Analog Converter (DAC) that can decode 24-bit/96kHz high-resolution audio without breaking a sweat. This is made possible by its new PCM5102 chip, which enhances the internal digital filter's linearity for superior sound output.

You also get a Signal-to-Noise Ratio (SNR) of 108dB, while the new LMH6643 op-amp inside turns the unit into a 150ohm headphone amplifier. As far as I/O and connectivity go, the E10K comes with two 3.5mm audio ports, a coaxial audio port, and a MicroUSB port. Some other noteworthy features include a convenient volume control dial and a slim aluminum case with a brushed metal finish.

“Packed with features like high fidelity audio decoding and trouble-free amplification, FiiO’s E10K belies its diminutive form factor.” — Rajat Sharma, Product Tester

FAQs

Why does my PC need a sound card?
Nearly all modern computers (desktops and laptops) available in the market feature integrated (on the motherboard) audio functionality, which ensures that both built-in (e.g. speakers) and external (e.g. earphones) work as intended. But even though this setup works well, it's extremely basic. If you want to use your PC with high-end gear like studio headphones and home theater systems, you need a sound card capable of driving all this additional hardware. It's also important if you want to fully enjoy high-resolution lossless music.

Should I go for an internal or an external sound card?
Generally speaking, internal sound cards are more powerful. They plug in directly into your desktop PC's motherboard, and offer features like switchable op-amp chips and a plethora of connectivity ports. However, if your target device is a laptop PC (or a gaming console), external sound cards are the way to go.

Can I install/set up the sound card myself?
Installing most internal sound cards isn't that hard, since you just have to plug them in your motherboard's expansion slot. External sound cards are even easier to set up, as they are usually powered via a USB port. In both cases, you also have to configure the associated drivers (if any) to get things up and running.

What to Look for in a PC Sound Card

Audio quality - The overall audio quality of a sound card is an extremely complicated equation that takes into account things like signal-to-noise ratio, frequency response, and total harmonic distortion. You generally want a sound card with signal-to-noise ratio over 100dB, but the best sound cards are in the 124dB range, which is a significant improvement.

Channels - A lot of decent, budget-friendly sound cards typically support 5.1 channel audio, but you can spend a little more to get one that can handle 7.1 surround sound. Some are even capable of upmixing 5.1 channel audio to 7.1, which is great if your headphones support 7.1 channels and your audio sources don’t.

Connectivity - Look for a sound card that has the jacks you need to plug in all of your equipment. Basic sound cards have 3.5mm jacks that work fine with most headphones and headsets, but look for one with RCA jacks or a TOSLINK optical connection if you’re hooking up to audio equipment that requires those types of connections.
