What's unique about the brand

HiBy is a hifi audio brand that built its own Android audio stack (Direct Transport Architecture) to bypass Android's standard audio processing for bit-perfect playback from any app. The company also developed its own high-resolution Bluetooth codec (UAT) that transmits up to 192kHz at 1.2Mbps across their DAPs, dongles, and wireless earbuds. What's more, they made the Darwin R2R DAC platform, a software-defined ladder DAC with user-selectable filters and downloadable firmware updates that allow users to tune the sound signature of their portable players.

What reviewers are saying

We read all the reviews. Here's what reviewers feel most strongly about:

  • They leverage their expertise in software, including the HiBy Music app and HiBy OS, to enhance the user experience and functionality of their audio products.
  • The brand focuses on utilizing high-quality components, such as AKM DAC chips, ELNA Silmic II capacitors, and discrete amplifier designs, to deliver detailed and dynamic sound.

Our favorite reviewer quotes:

  • "Beyond the sheer quantity of bass, the FD5 excels at conveying the nuances and complexities of the low-end, which is a remarkable feature for such a compact device at this price level. The FD5 is capable of accurately differentiating between various bass frequencies, including the deep rumble of a double bass and the punchy kick drum of a rock track." (https://moonstarreviews.net/hiby-fd5-review)
  • "It's wide, it's deep, it's tall and the sound of the Hiby Zeta is quite infectious in the most engrossing way." (https://mobileaudiophile.com/in-ear-earphones-iem-iems-reviews/hiby-zeta-review)
  • "From start to finish, I was in awe with just how crisp and nuanced the overall sound was. Every little nook and cranny that you can find in the songs whether it'd be the sweet percussions or the rich bass is presented in such a lovely way that made me love this album more than I already did."

About the brand

Burson is a hifi brand recognized for its modular op-amp design that allows users to easily swap components to customize their sound signature.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

Modular, Upgradeable Designs

We believe great gear should evolve with your system. That's why our products feature swappable opamps and power modules — letting users fine-tune performance or upgrade later without buying a whole new unit.

Pushing Class-A to New Heights

All our amplifiers operate in pure Class-A with high idle bias to achieve an effortless, dynamic sound.

What's your approach to customer support?

We love working directly with our customers — it's one of the best parts of being a small, passionate team. Customers can always reach out to us directly or go through their local dealer if they prefer. What to expect:

  • Fast and personal responses
  • Worldwide service centers (AU, EU, US, HK) to keep support convenient
  • Trade-in options for older gear
  • And even tips for mods and tweaks

What are your favorite tracks for showcasing the strength of your products?

"Vincent" – Sara K (from Are We There Yet): A stunning vocal performance with incredible acoustic detail.

"Don't Know Why" – Norah Jones: Her voice reveals micro-detail and tonal balance instantly.

"Limit to Your Love" – James Blake: Sub-bass extension, dynamics.

What other products pair best with yours?

We've had nearly 20 years of working relationship with Audeze, and our US facility — although it's changed address a few times — has always been close to Audeze's in California. Naturally, we love how Audeze headphones pair with our amps. Their planar designs thrive on the high-current, Class-A power that Burson gear delivers.
