The Deepest Bass on Earth

FATfreq presents the sub-bass IEM against which all audiophile Basshead IEMs are measured: the Maestro Mini.

The Mini's unique design ensures a concentrated bass response in the sub-bass region, without any undesirable bleed into the mids. As a result, it has earned its place as the benchmark for audiophiles and bass heads seeking uncompromised sub-bass performance. Recognized as the gold standard in bass-focused IEMs, the Maestro Mini continues to exceed expectations.

A FATfreq innovation pioneered and perfected for sheer bass power, the Maestro features 3D printed sound channels and a proprietary bass chamber tuned for perfect control. Meticulously engineered, the chamber utilizes cutting-edge acoustics to amplify low-frequency vibrations, setting the benchmark for deep, captivating Bass response.

Immerse yourself in the depths and clarity of bass like never before with the Maestro Mini!

FATfreq Tech

BASS CANNON™ (Patent Pending): Using proprietary dynamic woofers, bass chambers and acoustic damping networks, FATfreq was able to design the deepest bass ever recorded of over 30dB, expertly controlled below 200Hz with zero mid-range bleed. A FATfreq innovation pioneered and perfected for sheer bass power.

LINEAR IMPEDANCE: FATfreq uses proprietary circuits to correct the non-linear impedances of multi-driver systems. The different output impedances across all your devices cause frequency response to vary. Having this tech ensures consistency in frequency response for the entire FATfreq IEM lineup.

SONAR LA TROMPA™: Inspired by the anatomy of the traditional french horn, FATfreq uses exponential horn curvature for gain control and improvement of treble tonality via acoustics. The results are smooth, natural sounding highs grounded by a nice timbre in the mid and low frequencies.

Good little IEMs, unfortunately still too large for my tiny conchas. Bloom Service was great!

I tried the Maestro Mini at CanJam SoCal almost a year ago, and while I liked them I didn't have the funds to buy them at the time. I finally ordered them, only to find out that they were still slightly too large to use for more than 45 minutes to 1.5 hours. However, since I'm an outlier in terms of fit the rest of my review will focus on sound and quality.

Build quality seems good on the IEMs themselves, but the stock cable has a couple annoyances. First, and least problematic, there was a tiny bit of flashing on the 2-pin connectors that wasn't sanded off after molding (but you have to look closely to spot it). Another minor annoyance is the fact that the connector is right angled, which makes for a less clean look when using an extension at the computer. A more noticeable problem is minor driver flex on both sides, but as it only happens on insertion it's not too big a deal. The major problem is the chin slider. It simply doesn't stay put, and it's something I always use, so if the IEMs had fit me I would have had to buy a new cable to go with them. According to other reviews the upgrade cables Fatfreq sells have a similar problem.

As for sound, they're very good and much more balanced than the Scarlet Mini (which I also tried at CanJam). I still think my favorite sounding Fatfreq IEM (of the ones I was able to fit in my ears) is the Deuce, but the Maestro Mini came closer to fitting properly and has a bit more treble.

Bloom Audio was easy to work with on the return, and since the restocking fee and return shipping were clearly stated in their easy to find return policy I didn't get any nasty surprises. My only nitpick is that they didn't tell me how much the return shipping label cost, but based on subtracting the restocking fee from the refund amount return shipping was pretty inexpensive (in fact it was surprisingly low, I highly recommend letting them send you a label if you have to make a return rather than paying the consumer rate to ship it yourself).

Maestro Mini

Received my Maestro Minis today. They were well packaged. Package included the Maestro box, a card with the name of the individual that boxed the order, Thanks Quinton, another card with warranty info., a card with review info., a “Welcome to the Family” card from FATfreq, a Thank You note with receipt, and last but not least, a pack of Starburst fave reds flavor……yummy! So far I am enjoying the MMs, they are living up to the reviews I’ve seen online. Great bass, but no shortage of mids or highs. Vocals are clear and true. These are keepers. Time will tell whether they are end game.
