beyerdynamic Amiron 300 Review: Finally a comfortable design
- harmonious, high-quality design
- Processing not flawless
- excellent wearing comfort
The wearing comfort of the Free BYRD was perhaps the biggest weakness of beyerdynamic’s TWS debut, which was mainly due to the wide design of the earbuds. Fortunately, the beyerdynamic Amiron 300 are a completely different story.
Instead, the Heilbronn-based manufacturer has followed the path of some well-known premium manufacturers and opted for a rounded, rather narrow design that is somewhat reminiscent of the Sony WF-1000XM5 or Sennheiser Momentum True Wireless 4 in terms of shape.
The Amiron 300 are available in either black or cream. The latter model in particular, which we were able to test, offers a pleasant color accent to the rest of the housing with its silver manufacturer’s logo and decorative stripes.
The build quality is at a very good level, although the earbuds are largely made of plastic. However, it is not perfect, especially on the decorative strip there are some slight paint flaking – but these are barely visible to the naked eye – only the zoomed-in photo shows that the work here was not completely clean.
The beyerdynamic Amiron 300 are housed in a handy charging case, which measures 29 x 51 x 61 mm, is pleasantly handy and lies wobble-free on the table thanks to its flat underside. The scope of delivery also includes five additional pairs of silicone ear tips in sizes XS to XL, with size M already pre-installed but also included.
The wearing comfort of the beyerdynamic Amiron 300, on the other hand, was completely convincing. With a weight of 4.4 grams per earbud, they are among the lightest true wireless in-ears and, thanks to the rounded edges, remain comfortably in the ear for hours.
The earbuds are easily screwed into the ear cups after insertion and then sit comfortably, but also firmly enough to prevent them from falling out of the ears during fast movements. Top.
Features and battery life
- Bluetooth 5.3 with Multipoint
- LDAC codec; wearer detection
- adaptive ANC
The features of the beyerdynamic Amiron 300 leave virtually nothing to be desired. The earbuds are based on the Bluetooth 5.3 standard, which ensures a stable connection and long range. Thanks to Multipoint, two audio sources can be paired simultaneously.
In addition to the standard SBC and AAC codecs, Hi-Res sound is also supported via LDAC, provided your end device supports this. In conjunction with the 10 mm drivers, this should ensure an impressively full, detailed sound.
Of course, there is also a wear detection feature that automatically pauses playback when you remove the headphones. You can also set in the app whether this only applies to playback or also to phone calls and the touchpad.
A mono mode is also supported so that you can continue listening with just one earbud inserted. Another feature that should not be missing is active noise suppression including transparency mode.
In the companion app, you can choose between adaptive ANC, where the intensity is automatically adjusted to the ambient noise, or you can regulate the noise suppression yourself in five stages.
A wind noise detection function can also be added, which is designed to reduce wind noise. In practice, however, I hardly noticed any difference here. beyerdynamic also provides the Amiron 300 with six MEMS microphones, which filter out ambient noise and are supposed to deliver clear speech intelligibility.
Up to 38 hours of battery life
- 10 hours runtime without ANC
- 7 hours runtime with ANC
- 38 hours with the charging case
The battery life of the beyerdynamic Amiron 300 is outstanding. A full 10 hours are possible without active noise suppression for the pure earbuds, with ANC they last for 7 hours. This puts the Amiron 300 right at the top of the list of in-ear headphones with the longest battery life.
Only a few models, such as the Cambridge Audio Melomania M100 (our test), which are available at a significantly lower price, achieve these values. In combination with the charging case, you get a whole 38 hours of battery life.
The buds are charged in the charging case, with a full charge taking two hours. Top: Charging not only works via USB-C cable, but also wirelessly using the Qi standard if desired.
Operation and companion app
- Precise touch operation
- Sound adjustment via equalizer
- Quieter than many other premium in-ears
The beyerdynamic Amiron 300 are operated via touch control. It is extremely practical that the touch-sensitive outer sides are kept flat, which enables very precise and fast operation.
The operating concept is well thought out and does not lack any options. You can control playback, switch to the previous or next song, select ANC or transparency mode and even increase or decrease the volume, while it is also possible to call up the voice assistant.
The entire operation can also be freely customized in the beyerdynamic app. Here you can select alternative assignments or completely deactivate individual commands.
The beyerdynamic companion app provides information about the battery status of the earphones and allows you to adjust the sound using the equalizer. There are various presets to choose from, and you can also influence the sound yourself using a 5-band EQ.
However, I noticed that the maximum volume decreases slightly when you switch on the equalizer. Without active EQ, the beyerdynamic Amiron 300 play a little louder – but don’t reach the maximum volume of other premium in-ears. I would have liked a few decibels more here.
Audio quality, ANC and microphones
- 10 mm driver; 20 Hz to 40,000 Hz
- clean, detailed sound across all frequencies, but…
- … Sound image too narrow and appears one-dimensional
beyerdynamic gives the Amiron 10 mm drivers with an impedance of 32 ohms, which cover a frequency response of 20 Hz to 40,000 Hz and should therefore, in theory, deliver a rich, lively and detailed sound.
In practice, I also like the sound of the Amiron 300, but unfortunately the sound is not good enough for a place among the best in-ear models. The overall sound is too narrow and offers too little room for the treble and upper mids to develop.
In direct comparison with the Melomania M100 or the AirPods Pro 2, the sound is too one-dimensional and although the beyerdynamic Amiron 300 deliver an impressive level of detail in the highs, mids and even bass, they lack that certain something in all frequencies to really compete with the strongest rivals from Sony, Sennheiser, Bose and others.
In terms of sound, however, the Amiron 300 still deliver a very convincing performance. The beyerdynamic model outperforms most competitors in the price range up to 150 euros or 200 euros, especially in terms of the level of detail and bass reproduction.
However, the current price of around 250 euros is too high in my opinion. I would rather go for other models here.
ANC and transparency mode: Only good
- ANC and transparency mode at a good level
- Noise suppression can’t keep up with top models, however
The quality of the active noise cancellation and transparency mode is also only good enough for a good result. The ANC is able to suppress low, monotonous noises well (both in adaptive and fixed mode).
Medium and higher frequencies are greatly reduced, but still come through clearly. Here, the Apple AirPods Pro 2, not to mention the best ANC in-ears from Sony or Bose, deliver significantly better suppression of ambient noise at all frequencies.
The same applies to the transparency mode, which allows ambient noise to pass through more effectively to enable conversations with the earbuds in place. In the case of the beyerdynamic Amiron 300, this works well, but the competitors mentioned also deliver a noticeably better result and a noticeably more natural sound.
Microphone quality
beyerdynamic provides the Amiron 300 with a total of six MEMS microphones, but you shouldn’t reveal too much. Here too, the microphone quality is good, but not excellent.

The voice reproduction is noticeably lacking in detail, especially in comparison to the competition, and is not very dynamic. The intelligibility is okay, making the earbuds suitable for short phone calls. But here too, other manufacturers, especially Sennheiser, deliver audibly more.
beyerdynamic Amiron 300 Review: Conclusion
I’ll tell it like it is: the beyerdynamic Amiron 300 are a disappointment for me. Not because they aren’t good – the new earbuds from the German manufacturer undoubtedly are. But the competition in the premium segment is simply better in every respect.
That’s not what we’re used to from beyerdynamic, because the studio headphones and the new AVENTHO 300 over-ear Bluetooth headphones in particular play at reference level.
Unfortunately, this does not apply to the Amiron 300. On the plus side, the true wireless earbuds have top modern features including Bluetooth 5.3, Multipoint, LDAC codec and wearer recognition. The battery life is also excellent with up to 10 hours including active noise suppression.
Even the sound coming out of the in-ears is good to very good. However, the acoustics are noticeably lacking in spatiality, resulting in a very narrow, somewhat one-dimensional sound. ANC and transparency mode are also at a good level, but can by no means keep up with the top models, not to mention the microphone quality.
This means that the beyerdynamic Amiron 300 are currently too expensive for what they achieve. Although they really are good earbuds. If the price drops to 150-200 euros, the Amiron 300 are undoubtedly worth a look. At the moment, however, you’re better off with Sennheiser, Bose, Sony, Apple, Google or Cambridge Audio.
