Beyerdynamic, a name synonymous with professional-grade audio equipment, has obviously read the tea leaves and is investing into more consumer friendly gear as opposed to strictly studio. It recently launched a new line of Bluetooth wireless headphones, led by the Aventho 300 which I reviewed but didn’t quite love. Now, we’re talking about the Amiron 300 true wireless earbuds. These promise Beyer’s exceptional audio quality in a much smaller and quite frankly, more attractive package.
Priced at $399.99, the Amiron 300 sets sights on the likes of Apple AirPods Pro Gen 2 and Sony’s WF-1000XM5. After extensive testing, it’s clear that while the Amiron 300 excels in audio performance, certain aspects like active noise cancellation (ANC) and frustrating fitment issues leave a lot to be desired.
Design and Comfort
The Amiron 300 are stunning, especially in the cream variants that I have though you can also get them in black — its definitely one of the best looking earbuds I’ve encountered yet. They have a sleek, minimalist design with a premium feel. The earbuds have a refined matte finish that resists fingerprints and a subtle ridge on each earbud for improved accessibility to touch controls.
Unlike many competitors, the Amiron 300 adopts a stemless design, giving it a more compact and discreet profile. This not only enhances aesthetics but also reduces potential points of interference with clothing or accessories, making them ideal for users who prioritize a snug, low-profile fit. It’s nice not having anything stick outside your ears though that does put a lot of pressure on getting the right fit — but more on that later.
The charging case is compact yet sturdy, with a smooth hinge mechanism that exudes durability. It features a soft matte finish, giving it a very premium feel while also resisting fingerprints and smudges. Its rounded edges and lightweight build make it easy to slip into a pocket or bag without adding bulk. The case also features an LED indicator to display battery status, ensuring users are always aware of their remaining charge and a USB Type-C for charging.
Comfort is a crucial factor for true wireless earbuds, and Beyerdynamic has designed the Amiron 300 with ergonomics in mind. The lightweight structure ensures they sit comfortably in the ears without excessive pressure, making them suitable for prolonged listening sessions. However, a key aspect of comfort and sound quality hinges on the ear tip fit. The Amiron 300 includes multiple ear tip sizes, and achieving the right seal is essential for both passive noise isolation and optimal audio performance. A poor fit can result in diminished bass response and sound leakage, significantly affecting the listening experience.
Unfortunately, I struggled to find the right fit despite rotating through all the included oval shaped ear tips. Regardless of which ones I tried, I couldn’t get the buds to sit properly in my ear which not only compromised seal but led to an even more frustrating issue. The earbuds remained loose in my ear, and because they kept slipping, the wear detection would activate randomly, pausing playback or turning off one or both buds. This became so frustrating that I initially assumed my review unit was defective. After having Beyerdynamic send a replacement and encountering the same problem, I worked with their rep where we discovered that it was down to the poor fit in my ear.
This is where memory foam tips could have made a massive difference. Beyerdynamic included them with their Free Byrd earbuds but, oddly, left them out of this more premium offering. Foam tips mold to the ear canal, providing both superior comfort and a tighter seal, which would have likely improved bass response and passive noise isolation. Given how much I struggled to get a proper fit, I strongly believe the Amiron 300 could have greatly benefited from their inclusion. As it stands, these earbuds simply aren’t the best fit for my ears unless I purchase aftermarket memory foam tips—something potential buyers should consider if they face similar issues.
Features and Functionality
The Amiron 300 is equipped with customizable touch controls, allowing users to tailor functions such as playback, call handling, and ANC modes via the Beyerdynamic MIY app. The touch-sensitive surfaces are responsive, providing a seamless user experience. However, despite the well-thought-out design, I found the touch controls to be less than ideal for daily use. They often felt unintuitive, requiring precise taps that didn’t always register as expected especially because of the small size of the buds.
And this had the knock on effect of aggravating the wear detection issue I was already facing. Ultimately, I kept to using my connect device to control media rather than relying on the touch gestures, which proved to be more reliable and convenient in everyday scenarios. That said, the wear detection works well, automatically pausing playback when the Amiron 300 are removed and resuming when reinserted but this can also be an issue as I’ve mentioned above.
Connectivity is robust, thanks to Bluetooth 5.3 support, offering a stable connection with minimal latency. The inclusion of multipoint connectivity allows seamless switching between devices, a boon for users juggling multiple gadgets. I had no issues connecting to my devices and the switching between Macbook and my iPhone was pretty good. For high-resolution audio streaming, the Amiron 300 supports LDAC and AAC codecs, catering to both Android and iOS users.
The Beyerdynamic MIY app adds another layer of functionality, allowing users to fine-tune their listening experience. Additionally, the app provides an EQ adjustment, enabling users to tweak the bass, mids, and treble to their liking. There are a few presets to choose from and you can create and save two custom ones. There’s also controls for the ANC, control customisation, low latency and side tone. Firmware updates can also be managed through the app, ensuring the earbuds stay optimized with the latest improvements and fixes.
Audio excellence
When it comes to audio performance, the Amiron 300 delivers superb midrange clarity and a balanced sound signature. It’s powered by a custom 10mm driver that is capable of delivering Hi-Res audio. Vocals and instruments sound incredibly natural, with an emphasis on detail and separation. Acoustic tracks and vocal-heavy music shine, with crisp articulation and a spacious soundstage.
Bass response is very good, assuming you have a better fit and seal than I did. But even with my less than perfect fit, I could appreciate the rich, warm tones and clean bass. I enjoyed listening to my rotation of video game and movie soundtracks and the Amiron 300 was quite pleasant to listen to from the EDM tones of CyberPunk 2077 to the orchestral set-pieces of Bear McCreary’s Lord of the Rings: The Rings of Power soundtrack.
Vocals are clean, without being sibilant or shouty while the mid range and bass kicks in just well enough to round off tracks for an enjoyable listening experience. Sadly, that wasn’t always the case for me given the aforementioned poor fit which meant I often lost out on bass while also having to deal with the intrusion of ambient sound around me. A proper seal is crucial to experiencing the earbuds’ full sonic potential, and without it, much of the depth and richness in the low frequencies is lost.
Interestingly, the Amiron 300 doesn’t support Dolby Atmos, spatial audio or even head tracking, a feature that the AirPods Pro do. This really is a kick in the teeth for the price and I’m not sure why this was excluded. As a result, these buds aren’t the best for sound staging when playing mobile games but I’d be lying if I said games sounded bad because they don’t. The same qualities that make the Amiron 300 great for music listening apply here — at the least, you’ll enjoy the tunes coming from Candy Crush as you play. They also have a low-latency mode which is useful in faster paced games like Warzone Mobile.
Call quality on the Amiron 300 is fine. The buds deliver callers voices with clarity and natural sounding warmth while also carrying your voice without too much compression. That depends on your enviroment as the buds will compensate for ambient noise. I often found myself having to speak much louder while taking phone calls on the street lest callers would complain and ask me to repeat myself a lot. Listen to the sample below for your own reference.
Noise cancelling and transparency
ANC performance also suffered as a result though objectively speaking, I do think the Amiron 300 are not best in class here. I felt the same with the Free Byrd where they do just enough to eliminate certain hums and low frequency sound but mostly fail at dampening a lot of noises. I’ve tested them on the train, walking through busy city streets, and even working out in the gym. The Amiron 300 did such a lacklustre job of silencing the environment that I often had to double check that ANC was actually on.
Not only that, but I always had to increase the volume to 100% just to keep hearing my media. That’s obviously not great on the longevity of your ear drums but it speaks to the unimpressive noise-cancellation. If silence is a priority, these aren’t the best choice for ANC, as they struggle to block out external sounds effectively.
The Amiron 300 also have a Transparency mode, which does what it says on the box — amplifies ambient sound so you don’t have to take your buds off to hear train announcements or order a coffee. Its fine overall but I never actually felt I needed to use it since I could already here plenty even when ANC was active. There’s controls in the Beyerdynamic app to adjust the strength of the ANC but I couldn’t perceive any differences by doing so. Most people will leave it on maximum I think.
Overall, when it comes to noise-cancellation and transparency, the Amiron 300 comes far behind competitors like the Apple AirPods Pro, which in my experience are the best noise-cancelling ear buds.
Battery life
The Amiron 300 have some pretty good battery life. You’ll get 6 to 7 hours out of the buds with Noise-cancelling active but if you turn that off, you then get 11 hours which is great. I find that working at home, I can turn off the mostly useless ANC and the buds will get me through the entire workday with plenty to spare. Inside the case, you’ll get an additional 28 hours so effectively, three more charges to the buds.
A welcome touch is fast charging which will give you two hours of listening with just 10 minutes in the case. That’s handy. And speaking of the case, the Amirons case is Qi-Wireless compatible so you don’t have to be limited to finicky cables — just plonk it on your beside charger or even the charging pad in your car and you’re good to go. I can’t complain about battery life at all.
Final Verdict
With the Amiron 300, Beyerdynamic has refined its true wireless earbuds design to great effect. They sound amazing with great clarity and body while the gorgeous design stands out from an increasingly crowded earbud market. These are buds you buy because you want to look good and you want to hear good.
And while I can’t say that you will have the same fitment issues like I did since all our ears are uniquely shaped, its something unusual that I’ve never experienced with other earbuds that I’ve reviewed. Of course, you can always go out and buy some third-party ear tips that work for you but I do think Beyerdynamic dropped the ball by not including memory foam tips for people like me.
Lastly, if noise cancellation is important to you, then these aint it and that’s truly disappointing for such a premium set of buds. There are much better noise-cancelling earbuds out there especially at the $399 price point. Especially if you are an iPhone user, the AirPods Pro will give you far more for your money while Android users will get more from Sony’s XM5’s.
