Choosing the Best Audio Interfaces for Smartphones Under ¥50,000: 10 Recommended Models

“I want to record or livestream using my smartphone, but I have no idea which audio interface to choose...”

Many musicians and creators have probably found themselves facing exactly this problem.

In recent years, improvements in the performance of both iPhones and Android devices have made it possible to achieve high-quality recording and livestreaming using nothing more than a smartphone. As a result, an increasing number of audio interfaces that can be connected directly to smartphones have appeared on the market. That said, sound quality, connection methods, device compatibility, and available features vary considerably from one product to another. Some models excel at recording guitar, while others are particularly convenient for livestreaming and video production. Choosing the right interface for your specific needs is therefore essential.

In this article, we have carefully selected 10 recommended smartphone-compatible audio interfaces priced at ¥50,000 or less.

Whether you want to shoot videos of yourself playing guitar, record easily while on the go, or improve the audio quality of your livestreams, we will clearly explain the features and key advantages of each model so that you can find the one that best suits your needs.

⚠Important!⚠
Even if you find the product you want, don’t rush to buy it just yet!

Be sure to check whether your smartphone or other device is compatible with the audio interface. Depending on your device’s operating-system version and connection port—such as USB-C or Lightning—you may find that the interface cannot be used as-is after purchase. In some cases, you may also need to purchase an additional adapter, such as an official Apple Camera Adapter or an OTG cable.

For each product, I have included a link to the manufacturer’s official page where you can check the detailed system requirements and operating environment. Please be sure to check this information in advance and choose a product that is compatible with your own setup!

*Please note that the list of compatible devices published on a manufacturer’s website may not always be up to date. For the latest information regarding system requirements and compatible devices, please contact the manufacturer directly.
