Fischer Audio Omega Spark review

“Everyone has the fire, but the champions know when to ignite the spark.” ― Amit Ray

The Fischer Audio Omega FE-321 (Spark) is a lively little wonder of an IEM with a sparkly, bright sound and tiny footprint. The current price is US$59. Below is the description from the folks at Fischer Audio:

About Omega Spark

Omega Spark is a petite in-ear headphone that packs a punch above its weight. Offering excellent audio quality of clear, distinct highs with sweet lows and mid-lows, the in-ear headphones will bring out the best of a wide genre of music. Combined with a striking red-black housing combination and durable braided TPU cables in a matching red, Omega Spark has the looks to match its performance. With a sporty, modern look and bendable memory wire over-the-ear design, the Omega Spark will provide a comfortable fit for any time of the day. Omega Spark is especially recommended for ladies and youth because of its small body design which will sit snuggly for consumers with smaller ears.

I received this sample unit in exchange for my honest review. I have no affiliation with the company and this review is based on my own opinions.

The Spark comes in a nice looking box made of smooth cardboard. On the front, there is a clear image of the earphones giving you an idea of the shape and style. On the back is a handy frequency response graph along with a genre performance chart.

Music Recommendations – Omega Spark:
Hip Hop / RnB Good
Pop / Electronic Good
Rock / Metal Very Good
Classical Excellent
Jazz / Blues Very Good

There are also some specifications in four languages including English, Dutch, French and Russian. Speaking of specs here they are:

Driver Unit 7 mm
Sensitivity 95 dB ± 3dB
Impedance 16 Ohm
Frequency Range 20 Hz – 22KHz
Max. Power 50 mW
Cable 1.2 m, TPU
Plug 3.5 mm stereo plug

On the front of the box is a magnetic flap which opens up to reveal the inside cover and the earphones in a clear window. There’s a host of information here detailing the accessories, wearing instructions, a detailed breakdown of parts and phone controls.

Build and accessories

Included in the box are 3 pairs of silicone tips, 1 dual flange tips and 1 foam tips. There is also the Fischer Audio black carry case.

Anyone familiar with my reviews might remember that the included tips with most IEMs are too small for me. Again that is the case here, so for testing I had to dig something out of my personal extra-large tip collection (thanks to Sylmar and 1clearhead!)

The first thing that came to mind when I saw these is that they are tiny! I mean really small. The housing is made from a translucent red plastic that looks really neat. On the side is the Fischer Audio logo. The housing feels very strong and I doubt that any type of normal usage could ever damage them.

The cable is red to match the earphones and is accentuated by the black memory wire, microphone, Y-splitter and 90 degree plug. It’s a smooth plastic sheath that is resistant to tangles and feels durable.

On the left side is the microphone and in-line remote. The remote enables you to play and pause music as well as skip or rewind tracks. When testing the mic, the person I was talking to said I sounded very clear.

There’s a cable cinch above the Y-splitter to help with secure fit while moving about. The cinch and splitter are both made of a hard rubber.

The cable ends in a 90 degree plug that has a decent strain relief on it.

Fit and isolation

The Omega Spark actually fits me quite well, better than the Twin actually. They’re so small it’s easy to forget that you’re wearing them.

Due to their small size and light weight, the Spark is very comfortable and can be worn comfortably for long periods.

Sound isolation is average.


Testing was done primarily with my Benjie K9 and XDuoo X2 DAPs, Samsung Galaxy Note 5 and desktop PC.

The Spark has a lively, energetic and bright sound. As a result, the detail is above average and I definitely agree with Fischer Audio’s genre recommendation here as they are very well suited to classical music.

The bass on the Spark is rather good, although not as accentuated as it is with the Omega Twin and Ace models. Sub-bass has a surprising amount of rumble to it as well which I wasn’t expecting at first. Overall the bass is what I like to call ‘tidy’ but still has enough impact to move the music.

Mids are a bit drier than the other Omega models but still sound musical enough. Because of this they have above average clarity. Female vocals in particular sound good on these though sometimes get intruded upon by the aggressive treble. Normally this happens with bass tones but it’s the opposite with these.

The treble is up front with these. As a result, there’s plenty of detail coming through but it can sometimes border on edginess and may become fatiguing. I would have liked to see the treble tamed just a little bit to avoid those harsh peaks.


Omega Spark Vs Omega Ace

The Ace is warmer and darker than the Spark. Bringing a lot more bass to the table and more fullness to the mids. The treble on the Ace is also much more relaxed and rolled off, resulting in a smoother presentation.

Omega Spark Vs Omega Twin

The twin has much more bass impact and is warmer in the mids. Personally, I found the fit of the Spark much easier due to the elongated shape of the Twin which combined with the angle of the cable made them awkward. The Twin is much easier to drive, requiring significantly lower volume levels.


The Fischer Audio Omega Spark is the smallest IEM I’ve ever used. They’re absolutely minuscule but their sound is anything but small. Lots of focus has been put on the high frequencies, paired with a fairly tame bass. Plenty of details come through and for certain music genres, this is a winning combination. If you listen to a lot of classical music these might be worth your interest.
