2025 Annual Headphone Shootout Part One: The In Ear Monitors

It’s been a crazy March Madness. That means it’s also time for our annual Headphone Shootout. With March Madness, you sometimes get surprises with teams performing over their seeding. The same can sometimes happen with our Headphone Shootout, with some headphones preforming better than their pricing. We separate the headphones into two parts: In-ear and Over-the-ear.

The Creative Aurvana Ace Mimi came color printed box with photos and specs of the IEM. Opening the box revealed a well-protected product, held in place with custom molded paper. Materials used in the construction was mostly plastic with some metal and rubber. Quality of materials used as well as fit and finish was very good. Also included was the manual, charging cable, additional ear tips, and carry bag.

 


I like the design of the Creative Aurvana Ace Mimi. They are a traditional True Wireless design with a ton of features. There’s Bluetooth 5.3 LE Audio, Hybrid Adaptive ANC, LDAC, and xMEMS drivers. They even come with MIMI sound Personalization thru the app, so you can tailor the sound to you. The app also includes other sound customizations.  All of this is a huge bang for the buck with MSRP only $129. Let’s see how they sound.

 


Adele: Rolling In The Deep-  Acoustic guitar was crisp with really good resolution of the fingers plucking the strings. Hi-hat  and cymbal was really crisp and clean. Bass drum was dynamic with good low-end extension and authority. Piano also sounded natural. Vocals were silky smooth with good texture of the timbre.

Rush: Tom Sawyer-  Hi-hat and cymbal were crisp and clean. Snare drum was dynamic with good resolution of the pad. Kick drum was also really dynamic with really good low-end extension and played with really good authority. The tom drums were equally dynamic with really good pitch definition. Vocals were smooth like honey with great timbre. Guitar was nice and raw

Tiesto & Sevenn: Boom- An excellent bass torture track. It had multiple different bass beats. Some were nice and tight and not extremely deep. Some were deeper and hit hard. And some were really deep, and with a ton of authority that I could even feel in my earlobes!

 


Next up is the 1More Penta Driver. Unlike the other products they are a corded headphone. 1More is a budget headphone brand known for providing a big bang for the buck. And the 1More Penta Driver is an excellent example of this, providing an IEM with 5 drivers.  MSRP is only $169.

The 1More came in an excellent color printed box with phots and specs of the IEM. Opening the box revealing a well-protected product held in place by custom molded paper. And I was surprised with the packaging: it looked like a product at 3x it’s price! Materials used in the construction was mostly plastic with some metal and rubber. Quality of materials used, as well as fit and finish, is very good. Also included is the audio adapter, additional ear tips, carry bag, and manual.

 

I really like the design of the 1More Penta Driver. It uses four planar diaphragm drivers, and a dynamic driver, for a hybrid design. The planar drivers provide great mids and highs, while the dynamic driver provides better bass performance. The silver plated OFC wire helps provide a cleaner sound, with the in-line remote is for hands free calls. And if a short ever develops in the cord, it’s detachable for easy replacement. All of this seems to be a recipe for great sound. Let’s see how they sound.

 

Adele: Rolling In The Deep-  Hi-hat, cymbal, and tambourine were all really crisp and clean, with really good resolution to resolve them. Claps were dynamic. Piano sounded natural with good harmonics. Acoustic guitar had good resolution of the strings being plucked. Vocals were really smooth with good texture of the timbre.

Rush: Tom Sawyer-  Hi-hat and cymbal were really crisp and clean. Snare drum was really dynamic with good resolution of the pad. Kick drum was also dynamic with good low-end extension and played with authority. The tom drums provided similar dynamics with great pitch definition. Guitar was nice and raw. Vocals were silky smooth with great texture.

Tiesto & Sevenn: Boom- This is an excellent bass torture track. There were a bunch of different types to beats. Some were tight and not really deep. Some were deeper and hit really hard with good authority. And then some were really deep and resonated my ear canal. They all were really clean, and played with really good output and authority.



Now it’s time for the Beyerdynamic Amiron 300. Beyerdynamic is a German company that is known for hi-end headphones. Many of them are audiophile studio monitors.

The Beyerdynamic Amiron 300 came in a nice-looking color printed box with photos and specs of the product. Opening the box, I see a well-protected IEM held in place by custom molded paper. Materials used in the construction was mostly plastic with some metal and rubber. Quality of materials used, as well as fit and finish, was very good. Included was the charging case, ear tips, charging cable, and manual.

 


I really like the design of the Beyerdynamic Amiron 300. It’s a true wireless design. It also has ANC through the app, where you can control the ANC and transparency mode. Through the app you can also personalize the sound to you. I also like a bit more bass, so the EQ in the app also helps me to tailor the sound. It’s a combination of features for a great product. Let’s see how it sounds.

 


Adele: Roling In The Deep-  Hi-hat, cymbal, and tambourine were really crisp and clean with really good resolution. Claps were really dynamic. Piano sounded really natural with good resolution of the strings and very good harmonics. Acoustic guitar provided very good resolution of the plucking of the strings. Kick drum was really dynamic with very good low-end extension, and played with very good authority. Vocals were silky smooth with excellent texture of the timbre.

Rush: Tom Sawyer-  Hi-hat and cymbals were extremely crisp and clean with very good resolution of the impact. Snare drum was extremely dynamic with excellent resolution of the stick on the pad. Kick drum was also really dynamic, tight, with excellent low-end extension and played with really good output. Tom drums were equally dynamic, with excellent pitch definition. Guitar was nice and raw and vocals were smooth like honey with very good texture.

Tiesto & Sevenn: Boom- an excellent bass track. There were multiple types of bass beats. Some were nice and tight and hit really hard, like a punch to the chest. Some were deeper, and still hit really hard. And others were really deep and resonated my ear canal. All of them were really clean and played with a ton of authority.

I love the design of the Technics EAH-AZ100. They are a traditional looking true wireless IEM, but they use driver technology used in their reference class EAH-TZ700 wired in-ear monitors. It’s a 10 mm magnetic fluid driver. There’s also Adaptive Noise Cancelling, as well as an app to customize the sound to you, utilize the ANC, as well as additional features. And the spatial audio optimized for Dolby Atmos, is really cool! It sounds like an excellent product, let’s see you they sound.

 

Adele: Rolling In The Deep-  Hi-hat, cymbal, and tambourine were so crisp and clean, with so much resolution. Claps were dynamic. Piano sounded really natural with excellent harmonics. Acoustic guitar had really good resolution of the strings being plucked. Kick drum was really dynamic with really good depth and output. Vocals were silky smooth with very good texture of the timbre.

Rush: Tom Sawyer-  Hi-hat and cymbals were really crisp and clean with excellent resolution. Snare drum was extremely dynamic with excellent resolution of the pad. Kick drum was equally dynamic with excellent low-end extension and played with a ton of authority. Tom drums were also really dynamic with excellent harmonics and pitch definition of the midbass. Guitar was nice and raw. Vocals were smooth like honey with great texture.

Tiesto & Sevenn: Boom- and excellent bass torture track. The higher bass beats was nice and tight and hit hard like a punch to the chest. Some were deeper and also hit really hard. And some were so deep and played with a ton of output. All of the bass was really clean and played so loud.

 



Last, but not least, is the JBL Tour Pro 3. JBL has been providing great product for almost 80 years, and they have a long history of providing headphones with their JBL sound. They also don’t rest on their name. JBL continues to develop new products of excellent quality. This is evident with their JBL Tour Pro 3.  MSRP is $299.

The JBL Tour Pro 3 came in a great looking color printed box, with photos and specs of the product. Opening the box revealed a well-protected IEM held in place by custom molded plastic. Materials used in the construction was mostly plastic, with some metal and rubber. Quality of materials used, as well as fit and finish, was very good. Also included was the charging case, charging cable, audio cable, additional ear tips, and manual.

 


I love the design of the JBL Tour Pro 3. They are a true wireless IEM, with a boatload of features. You get Adaptive Noise Cancelling. JBL Spatial 360 with head tracking, and a smart charging case. Not to take away from the legendary JBL sound, but the smart case is a game changer. Leave your phone in your pocket. The case has a color screen to manage settings, as well as see songs, and even texts! It’s a plethora of features.  Let’s see how it sounds.

 


Adele: Rolling In The Deep-  Hi-hat, cymbal, and tambourine were really crisp and clean with excellent resolution. Claps were crisp and dynamic. Piano also sounded really natural with excellent resolution and harmonics. Acoustic guitar had excellent resolution of the plucking of the strings. Kick drum was also really dynamic with excellent impact, low end extension, and authority. Vocals were silky smooth with excellent texture of the timbre.

Rush: Tom Sawyer-  Hi-hat and cymbals were extremely crisp and clean with excellent resolution. Snare drum was really dynamic with excellent resolution of the pad. Kick drum was equally dynamic with really tight but very good low-end extension, and played with a ton of authority. Toms were equally dynamic and also had really good resolution of the pad and pitch definition of the midbass. Vocals were also smooth like honey, with excellent texture.

Tiesto & Sevenn: Boom- An excellent bass torture track. There were multiple types of bass beats. Some were higher in pitch, really tight, hit like a punch to the chest with excellent output. Others were deeper, still tight, and hit really hard. And then some were really deep, and hit so hard it got my ear canal to resonate a bit.

 


To test Bluetooth performance, we go way above and beyond rated specs.  We want to see the breaking point.  My home has a basement, main floor, and 2nd floor, for 3 floors.  Paired with my phone kept in my basement, I test how for it will go between walls, and much more…between multiple floors, to check its usable range.  And then what its range is out in the open. 

Creative Aurvana Ace Mimi:  no glitches in basement and main floor, and even glitch free on 2nd floor.  Out in the open it was glitch free for over 200 feet. Amazing Bluetooth performance!

Beyerdynamic Amiron 300:  no glitches in basement or main floor, small glitch on 2nd floor but easily usable, and one minor glitch at 175ft, usable over 200ft.  Excellent performance.

Technics EAH-AZ100:  no glitches in bas


ement, main floor, or even 2nd floor. And no glitches out to over 200ft. Amazing Bluetooth performance!

JBL Tour 3 Pro:  no glitches in basement, 1 minor glitch on main floor, and no glitches on 2nd floor. And no glitches out to over 200ft. Excellent performance.

 


I also tested the ANC.  Both ANC with and without ambient mode. Here are the findings:

Creative Aurvana Ace Mimi:  the ambient mode worked extremely well, allowing all of the ambient environment in.  For ANC, it removed around 70%.

Beyerdynamic Amiron 300:  The ambient mode was similar, allowing all of the ambient environment in.  For ANC, it was amazing, removing around 95%!

Technics EAH-AZ100:  again the ambient mode was similar with all of the ambient environment coming in.  ANC was around 90-95%, for very good performance.

JBL Tour 3 Pro: the similar ambient mode performance continues, with all of the ambient environment coming in. ANC was around 95%, for excellent performance.

 


For overall sound, the Creative was just a hair on the bright side for sound signature, with great resolution and bass output. But while just slightly, it did have a slightly lower bass output from the rest.  The 1more had slightly better bass output, and better bass dynamics and resolution, and with 5 drivers had excellent resolution and smooth sound with a wide and deep soundstage.  It also benefited from all of the cost going towards the drivers and not the wireless components and charging case. It had a sound signature that was slightly on the warm side.  Beyerdynamics had a neutral sound signature, really wide and deep soundstage with excellent imaging and resolution, and tied with JBL for the most bass output.  Technics was just a tad warm with the sound signature, with thanks to their special driver had resolution that was just a tad better on the highs than it was on the midbass. And while it had excellent bass output, it was jus a tad less than Beyerdynamic and JBL. JBL had a neutral soundstage, excellent resolution, and a soundstage that was both wide and deep.

 


When it comes to headphones, everyone has a preference to the sound they prefer.  Depending on your preferred sound signature could determine which IEM is the best fit for you.  The Creative Aurvana Ace Mimi provides a huge bang for the buck based on their price, and is just under the rest in overall sound quality, but has some excellent features.  If you can handle wired, the 1More Penta could be for you. It just doesn’t have the wireless features that most are looking for. Beyerdynamic managed to get their well known studio sound into their Amiron 300.  And with JBL you get both excellent sound, tons of features, and the best charging case that also includes a color touchscreen display for additional features.  Based on their design, features, quality, and performance, the Creative Aurvana Ace Mimi and 1More Penta have earned our Value Award, and the Technics EAH-AZ100 has earned our Highly Recommended Award, and the Beyerdynamic Amiron 300 and JBL Tour Pro 3 have earned our Editor’s Choice Award.  For more info and complete specs, check out their website at www.creative.com, www.1more.com, www.technics.com, www.beyerdynamic.com, and www.jbl.com.
