Today, we will review two TWS in-ear earphone models: the Beyerdynamic AMIRON 100 and the AMIRON 300. We will discuss all of their features, as well as their sound quality, and briefly compare them. 2025 was a turning point for Beyerdynamic. The brand finally entered the portable audio segment with a full line of wireless headphones. Previously, Beyerdynamic had only dabbled in this area with the Beyerdynamic Free BYRD. Our colleagues have already reviewed the full-size Aventho 300, and today, we will take a look at the TWS lineup – the Amiron 100 and Amiron 300 models. Despite their different appearances, the models are very similar in terms of sound and other features.

As the specifications show, there are significant differences between the two models. The Beyerdynamic AMIRON 300, more advanced earphone model, has a wider frequency response, LDAC codec support, a longer battery life on a single charge, etc. We'll discuss these features in more detail in the following sections of our review.

The packaging and accessories are also 99% identical in both models, as with the specifications. Both models come in high-quality cardboard boxes containing a pedestal with a case and a tray for spare ear tips. Under the tray is a manual and a box containing a Type-C cable. The only difference is the ear tips themselves. The AMIRON 100 model has regular tips, while the 300 model has slotted tips, which is common for TWS earphones. Both models come with five sets of additional ear tips and one set on the earbuds. Here's a special feature: The size of the earbuds is actually slightly smaller than the additional size M but larger than the additional size S. Therefore, there are actually six different sizes.
This is where the differences begin. The Amiron 100 model has an oval shape and is made of regular matte plastic. The Amiron 300 model has a classic rectangular shape and is made of soft-touch plastic.
Both cases are glossy on the inside. There are no complaints regarding ergonomics or comfort.
Now, let's talk about the headphones. Of course, it makes no sense to compare their shape because the Amiron 100 is a classic in-ear model (like the well-known AirPods) and the Amiron 300 is an earbud model. They both fit well in the ears, so it's a matter of personal preference. What's great about both models is the high-quality plastic, which is comfortable to hold and pleasant to the touch. It also doesn't collect fingerprints. Both models are available in Black and Cream colors. One cool design feature is the Beyerdynamic logo on the touch panels.
Functionally, the two models are almost identical. Both have an ear sensor for auto-pause, ANC (more on that later), touch controls, and a dynamic driver.
This is where the first technical difference between the two models becomes apparent. Both work with Bluetooth 5.3, but the Beyerdynamic Amiron 100 only supports AAC and SBC. In contrast, the Beyerdynamic Amiron 300 supports LDAC as well. They connect quickly, multipoint works, and the connection is stable – everything is top-notch.
Additionally, Beyerdynamic has released a proprietary control app for its new line of headphones. It is available for both iOS and Android. To be honest, it's exemplary. It's simple, concise, visually appealing, and, most importantly, fully functional. With it, you can configure the headphone controls, adjust the equalizer, update the software, and much more. The app also has a list of all models and their specifications, so it doubles as a reference guide.
First, let's describe how these modes work in general without going into too much detail. Compared to the market leaders, they are slightly inferior. In noise cancellation mode, noise is not completely eliminated, and the sound quality is not quite as clear as it is with more advanced models. However, the difference is actually small. The transparency mode could also be improved — there is some background noise and voices are not transmitted as loudly. Overall, though, it's not bad.
Now, let's compare the active noise cancellation (ANC) of the Beyerdynamic Amiron 100 and 300 models. ANC is essentially the second distinguishing factor between the models. The junior model only has ANC and transparency modes, while the senior model has adjustable levels of these modes and an additional Adaptive level. This provides more control and better performance. There is also a ANC wind noise detection mode, but it doesn't work perfectly.
The new models from Beyerdynamic aren't far behind. While they don't have the same battery life as the Anker Soundcore Liberty 5, you'll get a solid eight hours without ANC and six and a half hours with ANC on the junior Amiron 100 model. The senior Amiron 300 offers a pretty decent ten hours without ANC and eight hours with noise cancellation. Keep in mind, though, that turning on the LDAC codec automatically uses an additional 30% of the battery. With ANC off, we got 7 hours of battery life; with ANC on, we got 5 hours and 28 minutes, which is normal but not exceptional. The cases for both models provide an additional 2.5 charges for the earphones. Overall, the manufacturer promises 36-38 hours of battery life for the headphones and case combined, which is more than enough.
We've now reached the main part of our review of the Beyerdynamic AMIRON 100 and AMIRON 300. Naturally, we're all eager to learn about the sound quality of these earphones. However, before we discuss that, let's first say a few words about the microphones on these devices. Both models are equipped with high-quality microphones that provide clear, detailed sound. With ANC turned off, we couldn't detect any difference between them – they are both excellent quality and perform well. The only difference is that, thanks to the stem-in-body design, the voice is slightly louder on the junior model.
We thought long and hard about how to take a more 'calm' approach to this section, but nothing worked. We'll sing the praises of these headphones because both models produce superb sound quality. The first thing you'll notice when you start listening is that someone has finally installed a fast, high-quality driver in these headphones. TWS models often feel sluggish, especially in the lower range – there's weight and detail, but also a certain heaviness. Here, however, it's the opposite: lightness, speed and control with no loss of weight when needed. This applies to both models, because the only difference between them in the usual stock sound is that the Amiron 300 has a little more massiveness in the low frequencies. Using the equaliser, we were even able to make them sound the same. Interestingly, we don't know whether it's the signal processing or how they achieved it, but even with the AAC codec, there's no sense of loss at the edges of the frequency range. If you listen carefully, you can detect them, but they are so cleverly 'hidden' that they are almost imperceptible. We were particularly impressed by the high frequencies, which often suffer from compression, but here they are exemplary: clean, detailed, transparent and clear.
But things get even better when LDAC is enabled on the Beyerdynamic Amiron 300 – unfortunately, this feature is not available on the Amiron 100. According to AAC, the soundstage was not very wide or deep, but it immediately expands when LDAC is enabled. However, that's not the main change. More significantly, the detail in the midrange and bass improves – the headphones attempt to reproduce almost every sound. There is no emphasis on microcontrast, nor are there any attempts to smooth out the nuances. We have not yet encountered such sound quality in TWS headphones in this price range. The bass is fast, highly controlled and detailed. It is very reminiscent of the wired Beyerdynamic 770 PRO bass at 32 ohms, but with a little added weight. The midrange is clean, detailed and well balanced. The high frequencies remain unchanged to the ear, but if you listen closely, you will hear the moments that were 'hidden' on AAC.
Now, let's talk about the effect of ANC on sound. Here, we have an interesting situation. Despite the models sounding almost the same on AAC, ANC affects the sound differently. With the Amiron 100, the high frequencies are suppressed and there is less ringing and extension. With the Amiron 300, the sound is more classic with a little extra bass, so it is better to use a separate equaliser setting for ANC to achieve the same sound as without it.
Now that we've reached the end of our Beyerdynamic AMIRON 100 and AMIRON 300 review, it's time to summarize the results. It is always interesting when a leader in the stationery sector enters the portable market, but this launch is truly groundbreaking. Beyerdynamic has not only introduced attractive true wireless stereo (TWS) earphones, but has also released them with a focus on sound quality rather than fashion trends. This bold decision finally brings something different to the market – something that has been lacking for a long time. Both models boast impressive functionality and build quality. Ideally, we would like to see more 'mirror' models, such as the 300 series internals in the 100 series housing and vice versa, but for now, we have to choose between sound quality and form factor. However, for fans of 'buds', we would highly recommend the Beyerdynamic Amiron 300 as the first model to try. Sorry Technics AZ-100, but these are more interesting. For fans of wireless earphones with a stem, the Amiron 100 is an excellent choice.
