Beyerdynamic Amiron 300 Review (2025)

The Beyerdynamic Amiron 300 are compact and straightforward stemless earbuds that tuck comfortably into your ear. This can make it a little hard to locate their touch-sensitive buttons, but it also makes them comfortable to wear under a hat or while resting your head on something. The touch sensors respond effectively when tapped. They are available in black and cream (off-white). I received the latter for testing.

The earbuds do a decent job of staying in my ears, though they occasionally require a little nudge to stay perfectly seated. The box includes five sets of silicone eartips of different sizes to help you find the best fit. I found them adequate for walking but not secure enough for running or other sports. The IP54 rating should ensure they can survive a bit of sweat or rain.

Inside, the earbuds have 10mm drivers and can reproduce 20Hz to 40kHz, which qualifies them for High Resolution audio. They use Bluetooth 5.3 and support the AAC, LDAC, and SBC codecs. They also support Bluetooth multipoint, though in testing, the earbuds struggled to maintain a connection with two devices at once.

The earbuds weigh just 0.2 ounces each and come in a spring-top case that weighs 1.8 ounces. I found the spring mechanism suboptimal: If you drop the case, it tends to launch the buds on impact. The case supports USB-C charging and Qi wireless charging.

The buds have sizable batteries, offering up to seven hours of listening with ANC on and up to 10 hours with ANC off, though your battery life will depend on listening volume and use of noise cancellation. The charging case provides an additional 28 hours of battery life. Beyerdynamic says 10 minutes of charging nets you two hours of listening time.

The Beyerdynamic App (available for Android and iOS) is intuitive and useful. It can be used without creating an account. The home screen shows most settings, and a second page offers an exhaustive list of options.

You get various EQ presets and a five-band custom equalizer for tweaking. You can also set ANC and pass-through levels and decide whether or not you want wind noise detection.

The app lets you enable or disable the smart assistant function and customize on-ear controls. You can also activate low-latency mode, various wear detection responses, the LDAC codec (depending on your phone), and automatic shutdown timing.

The Beyerdynamic Amiron 300 earbuds offer some passive isolation thanks to the in-ear silicone tips, as well as active noise cancellation (ANC) and transparency modes. The buds include six microphones to help manage external sounds. Overall, they do a fine job, though they can't match Bose's market-leading ANC.

At its lowest level, the ANC effectively reduces the lower frequencies of a busy cafe, allowing only voices and transients through. Boosting the ANC levels trims even more from the lower frequencies and reduces the volume of voices, though it doesn’t eliminate them completely.

The earbuds are adept at reducing noise below about 100Hz, which is excellent for lower-frequency droning sounds. However, they don’t respond well to head movements much while ANC is active, and they introduce audio artifacts akin to the sound of fluttering paper when you rotate your neck. This happens frequently enough that it detracts from the overall experience.

On the flip side, the transparency mode is impressive. The earbuds deliver a stunning transparency mode that’s almost as clear as having nothing in your ears at all. However, there’s a hint of white noise, and some audio artifacts are introduced if you move your head around.

Both ANC and transparency modes can detect and deactivate wind noise to avoid the clipping that sometimes occurs when wind hits the mics, which not all buds can do.

The earbuds don’t require tweaking to get a well-balanced sound response. The default EQ manages the audio signature quite well.

On The Knife’s “Silent Shout,” the buds deliver heavy, thumping bass and sub-bass while the synth melody punches crisply. Both levels of the vocal harmony are clear in the mix as well. The buds provide a wide enough soundstage to enjoy picking out the various instruments from left to right.

This relatively flat response plays well in Kendrick Lamar’s “Loyalty,” where Lamar’s and Rihanna’s vocals sound even when the deep sub-bass comes in; the melody doesn't sink into the background. The earbuds are quite respectable where sub-bass is concerned, too. They readily hit all of the deep notes in this track, which can be difficult for audio devices with small drivers.

Bill Callahan’s “Drover” further highlights the audio chops. From Callahan’s baritone vocals, which come through with a rich fullness, to the plaintive wailing of the electric guitar, the track’s lush instrumentation stands out. Even the background's subtle bass and room noise find their place in the mix.

The earphones put on a good show with classical music like John Adams’ The Gospel According to the Other Mary. They handily present the track's many instruments and adeptly bring the ambience of some of the lowest and subtlest notes and voices. In “Lazarus Rises From the Dead,” the buds provide a stunning sweep from hushed, subtle tones to a frightening cacophonous roar. All of the track’s eerie ambiance comes through with the wide soundstage, as the various instruments that create it have room to breathe.

The mics capture my voice clearly in a quiet room, though they have a somewhat distant sound. They struggle to suppress background noise.

Beyerdynamic's Amiron 300 earphones provide clear, well-balanced, and robust audio. They are also pleasingly understated, comfortable, and have respectable battery life. As good as they are, they don't quite match the performance of similarly priced Editors' Choice winners, which include the Bose QuietComfort Ultra Earbuds for noise cancellation, the Sony WF-1000XM5 for audio quality, and the Apple AirPods Pro 2 for iPhone integration.
