Back to Custom, Built for HiFi: NF ACOUS at SIAS 2026

From August 14 to 16, NF ACOUS exhibited at SIAS 2026 at the Shenzhen Convention and Exhibition Center (Futian), Hall 6. At Booth B10, we presented seven new models and met music enthusiasts, industry media, and content creators from China and around the world.

Our theme for the show was: Back to Custom, Built for HiFi.

 

Returning to Custom for New HiFi Needs

NF ACOUS was founded in 2014, with custom in-ear monitors at the center of our early work. Over the past decade, we have continued to build our expertise in custom-fit structures, acoustic implementation, ergonomics, and professional applications.

In recent years, our focus on universal-fit earphones has brought us into a wider range of listening scenarios and deepened our understanding of today’s HiFi users.

“Back to Custom” is not simply a return to the past. It means bringing everything we have learned back into a custom development system and using that foundation to create more products for the HiFi market.

To support this direction, NF ACOUS has established Custom Studio as an independent high-end division. Moving forward, it will take on more HiFi product development projects, keeping user requirements, acoustic development, production, and final verification closely connected.

 

One Engineer, One Product

At the heart of Custom Studio is a clear principle: One Engineer, One Product.

 

From understanding the user’s requirements and developing the acoustic solution to hand-building, adjustment, final verification, and delivery, the same engineer remains responsible for each product throughout the process.

The key is not simply hand craftsmanship, but continuity of responsibility. Keeping one engineer involved from beginning to end helps preserve the connection between the original requirements, later adjustments, and final result.

P4, P6, and P8: Three Custom Sound Directions

At SIAS 2026, Custom Studio introduced three new custom models together for the first time:

· P4 — Vocal Focus: greater emphasis on vocal presence and expression;

· P6 — Reference Balance: a balanced presentation with evenly distributed information;

· P8 — Super Bass: greater weight, presence, and character in the low frequencies.

 

These models represent three different sound directions rather than an entry-to-flagship hierarchy.

At the show, some listeners preferred the balanced and complete presentation of the P6, while the detail and bass performance of the P8 attracted particular interest from bassists, drummers, and other professional users.

The new P Series faceplate artwork was another highlight, giving users a wide range of finely detailed designs for further personalization.

NA25: New Ideas in Sound and Structure

Among the universal-fit products, the NA25 was one of the most requested models at our booth.

Marking a new direction for the NF ACOUS Music Series, the NA25 is the first model in the series to feature a flush 2-Pin connector. It also introduces a modular cable plug system, interchangeable sound nozzles, and a higher-spec cable. Together, these updates offer greater flexibility while giving the NA25 a more engaging and distinctive sound signature.

Seven Products for Different Listening Needs

Alongside the P4, P6, P8, and NA25, NF ACOUS also presented the NH20 2026, NM10, and TWS POGO.

The NH20 2026 features refined product details and improved ergonomics, with many visitors describing the updated fit as more natural and comfortable.

The NM10 is an entry-level professional monitoring earphone for singing, instrument performance, livestreaming, and recording.

 

TWS POGO combines wireless convenience with sound filters controlled through its dedicated app, offering more options for everyday listening.

 

Each product serves a different need. At NF ACOUS, we begin with the actual use case and choose the acoustic and engineering approach that best supports it.

Feedback from SIAS 2026

Throughout the show, overseas YouTube creators, Chinese audio reviewers, and industry media visited our booth to experience the products. Their feedback covered sound direction, fit, product structure, cables, and faceplate craftsmanship.

 

 

These direct responses will be valuable as our team continues to refine the products.

Thank you to everyone who visited Booth B10, listened with us, and shared your feedback. We also thank the media and content creators who took the time to learn more about our latest work.

Back to Custom, Built for HiFi.

Thank you for being part of SIAS 2026. See you next year!
