Often, manufacturers of laptops and ultrabooks, for the sake of compactness of their equipment and saving space under the device case, install far from the most powerful sound cards, which makes it problematic to work with sound, play, and even just watch movies. For this reason, so-called external sound cards have been developed that connect to a computer using a USB connector. They greatly improve the sound quality.

Recently, more and more similar models have begun to appear on sale. It may not be too easy to choose from them the most suitable and optimal in terms of cost and workmanship, especially if a person does not have special knowledge in this area. Therefore, we decided today to dedicate our review of the best external sound cards of 2020. However, let’s first look at what you should pay attention to when buying such devices.

What qualities are important for an external sound card?

First of all, you should decide whether this equipment is really necessary and whether it is worth buying. So, an external sound card will be useful for users if they need good and high-quality sound on a portable personal computer. Users may say that you can connect speakers or headphones, but this approach is fundamentally wrong. Additional speakers will increase the sound volume, but the quality will remain the same. An external sound card will also come in handy for laptop owners whose integrated part is out of order.

In most cases, such a device has small overall dimensions — with an ordinary flash drive or card reader. More expensive designs have a larger size — with an external hard drive. The most productive models have even larger dimensions, which are quite comparable with the portable computer itself. The capabilities of such equipment make it possible to make the sound clearer and stronger than that of an integrated element. Using such a card, you can connect several microphones, speakers, headphones and so on at once.

How to choose an external sound card?

The most expensive models are equipped with various indicators, buttons and volume control knobs, they have various kinds of interfaces available — analog and coaxial outputs. An external sound card allows almost professional audio recording. Often, this design is attached not only to a personal computer, but also to a tablet or phone. The setup is very simple, carried out using the buttons and controls directly on the case.

When choosing such a product, certain product qualities should be taken into account. For home amateur use, a card equipped with one input and an audio output is quite enough. For a small compact cinema, devices with two similar pairs are suitable. If the product is intended for professional use, then there must be at least 4 of these outputs. The bit depth of the external sound card must be at least 24 bits. If you plan to connect musical instruments, then appropriate sockets should be provided for them.

It will be very good if the card has support for the Digital Theater System or Dolby Digital sound standards, which allow you to work with multi-channel audio and video. This is important not only when watching movies or playing games, but also when editing music. An external sound card should not support the ASIO transfer protocol, but if such a function is present, it will be very good.

It doesn’t hurt the EAX technology that adds ambient sound effects, which is a nice bonus for the gamer who prefers applications that support multi-channel audio. When compiling our ranking of the best external sound cards of the year, we took all these points into account, as well as turned to feedback from users and sound professionals. We tried to take into account the ratio of price and quality of models so that the most expensive products are not included in our review. It’s time to analyze the performance of these products.

One of the smallest models in our entire review, however, the purpose of this device is quite wide, no adapter or any other additional elements are required for direct use. The equipment can work with USB 2.0 and 3.0 connectors, it provides high quality sound from a personal computer, laptop, various consoles such as Xbox or Sony Play Station. Built-in microphones and other similar additional functions are not provided here, which could not but affect the cost, of course, to a lesser extent. Dimensions and weight are small.

The product has the shape of a prism, the body is plastic — smooth matte on top with small inclusions, stylized as polished metal. The front side is made of glossy plastic, which leaves a lot of fingerprints. It has only two outputs — one for connecting a microphone, the second for headphones. In the central part there is a volume control, which is also stylized as metal. On the underside, there is a pad of velvety polyurethane, which allows the device not to slide on the surface.

The functionality is not too wide — it is limited to only two inputs in order to be able to connect two external sound sources. They are the same — for XLR / jack 6.3 mm. However, they have different purposes of application: the first one can be used both for connecting instruments and microphones, including condenser ones, which provide high sound quality, especially vocals. With their help, extraneous noise is well suppressed. This connector is equipped with a Midas brand preamp, although many users report very mediocre sound quality in their reviews. In addition, it is allowed to send a 48 V phantom load to the first channel. This can be done using a special switch located on the rear panel of the device.

Headphones can recognize two types of signals — processed, coming directly from a personal computer, and the original, which comes from a musical instrument. The latter function is provided by Direct Monitor technology. In order to adjust the volume of both channels, only one knob is provided — this point is considered by many users as a drawback. The translation of an audio signal from analog to digital and vice versa is carried out as 24 bits, its frequency is 48 kHz. This allows you to use a sound card for professional sound recording. Small dimensions make it easy to use the design in a small studio and even when traveling. The case is made of metal with additional stiffening ribs — this allows you to well protect the filling of the device from various kinds of mechanical damage.


  • Fairly good price;
  • Simplicity and ease of use;
  • There is a button for direct monitoring;
  • It is possible to support ASIO drivers.

The handles have a smooth stroke, which allows for fairly fine tuning. Outputs for headphones and monitors are separate, there is hardware monitoring of inputs. In particular, with the help of this sound card, you can listen to the dry sound of the guitar and combine it with the sound that has already been processed. In the design, you can also find four-segment peak meters.

The back side is quite simple. It has a combo output, as well as outputs used to connect monitors and a USB-C power socket. The minimum audio transmission delay is 64 samples, which means that the audio is transmitted almost in real time. The card allows you to provide +48V power for microphones, which is an undoubted advantage. The sound interface is at a decent level, even heavy and powerful headphones transmit sound well, have a decent volume margin. The timbres are transmitted evenly, the bass lines are not overwhelmed and do not tend to stand out. The inputs do not make noise, do not embellish or discolor the sound, creating the highest fidelity.


  • Good sound quality;
  • Acceptable cost;
  • Beautiful appearance;
  • Excellent ergonomics.


  • The USB-C connector is weak, it may begin to lose contacts over time.
