Beyerdynamic’s Amiron Zero marks the company’s entry into the open-ear, clip-on earbud market, a category that’s been quietly growing as listeners search for comfort and spatial awareness without sacrificing sound quality. Known for its studio-grade precision and refined design language, Beyerdynamic brings professional tuning and thoughtful engineering to a form factor that’s typically dominated by fitness-oriented brands. The Amiron Zero aims to combine the open, natural presentation of over-ear headphones with the freedom and portability of true wireless earbuds. But does this experiment live up to Beyerdynamic’s reputation for sonic clarity and craftsmanship? Let’s find out in this in-depth review of the Beyerdynamic Amiron Zero.

Look & Feel
I have only tried one other pair of open-ear clip-on earbuds in the past, but I was a fan of this new design and was interested to see what other manufacturers could do. Beyerdynamic brings its professional branding to clip-on earbuds, which piques my interest more than other names on the market. With that, there’s not a whole lot to say in terms of appearance. Beyerdynamic’s recent wireless products have a consistent theme that’s classy, refined, and easy to identify. If you’re unfamiliar with clip-on design, it might take a few seconds to figure out the best fit for the Amiron Zero, but once you get them on, it’s hard to ever notice them once you start listening to music.
Design & Functionality
The Beyerdynamic Amiron Zero features compact yet technically precise 18 × 11 × 4.85 mm dynamic drivers, tailored for an open-ear clip-on design with a frequency response of 20 Hz to 20 kHz. On top of that, users have access to a companion app through which they can apply 5-band EQ adjustments and select genre-specific presets, giving fine-tune control over bass, mids, and treble to suit personal listening preferences. In terms of functionality, the controls are touch-sensitive and intuitive; however, the response time can be a bit finicky sometimes.
Bluetooth
The Beyerdynamic Amiron Zero uses Bluetooth 5.4, delivering an efficient, low-latency wireless connection with a typical range of up to 15m. On the codec side, it handles SBC and AAC, so while it doesn’t support higher-bit codecs like LDAC or aptX, it still maintains wide compatibility with most mobile devices.
Battery Life
The battery life for the Amiron Zero is just passable for the price. You get up to 6 hours of playback from a single charge in the earbuds, and the included charging case adds about 14 additional hours, giving you a total of up to 20 hours of runtime. It also has 10-minute quick charging for 2 hours of playtime if you’re in a rush. The Amiron Zero gets outdone in this field, but it’s still serviceable as a product for daily use.
Soundstage
The Amiron Zero’s open ear design lends itself to having a naturally spacious soundstage. With its clip-on structure, it feels like the headspace has even fewer barriers than other open-ear designs. Both the left and right channels are completely separated, showcasing good spatial identity through hard positioning. It’s a fulfilling stereofield that is linear but wide. The output is flat, and the scale of the instruments is pretty plain, but the headspace allows for more precise imaging, helping the sound elements move around the mix with more clarity than in-ear wireless options in this price range.
Low End
There’s enough bass energy here to give the sound profile of the Amiron Zero a certain level of power. While this isn’t the most defined bass tone, the low frequencies are elevated to a consistent gain, placing them on the surface of this sound signature with a steady resonance and a pleasing punch. It lacks a clear shape, but the tone still has weight, even when it lacks resolution.
Mids
My main reservation with the midrange of the Amiron Zero is that everything sounds spread too thin. Instruments have a small surface area and lack a consistent edge that brings them to the front of mixes. This leaves some instruments feeling a bit underpowered, even when presented with a lot of room. Vocals are the clearest elements in the sound signature, but still aren’t quite as crisp.
Highs
The treble is the most expressive area of the Amiron Zero’s sound signature. The timbre has a wispy, airy texture to it without being anywhere near harsh. It’s a pleasant tone that allows for a detailed presentation that is colorful and controlled. Like the rest of the frequency response, the resolution of each note isn’t quite there, but the highs have much more velocity to them than the lows and mids.
Summary
The Beyerdynamic Amiron Zero successfully carves out a niche within the emerging open-ear category by offering a refined, spatially engaging soundstage paired with a lightweight, minimalist design. While it doesn’t quite deliver in battery life or midrange detail, its high-end clarity, wide stereo image, and customizable EQ make it a compelling choice for casual listening and everyday comfort. Audiophiles may crave more resolution and codec support, but for listeners seeking a balanced, airy alternative to in-ear wireless models, the Amiron Zero showcases Beyerdynamic’s signature polish in a fresh and innovative format.
