Review: Atomic Floyd Powere Jax


Atomic Floyd | In-Ear Monitor | $ 150.00

Atomic Floyd has become a company that I’ve learned to respect. Their design aspects are very unique and stand out of a crowd. They are very attractive, but don’t skimp when it comes to the sound that the headphones pump out. Their combination of these two makes the PowerJax a very great IEM in its price bracket.

Beautifully textured steel has become the signature of any IEM made by Atomic Floyd. There is plenty of reason for that as it really makes the IEM itself look aesthetically pleasing. As with the rest of their headphones, the PowerJax carry the same metallic, red, and black color scheme that is bold and stands out very well. With all that said, the PowerJax are just very beautiful.


Design: ★★★★


The PowerJax have a bit of a V-shape to their general sound signature. This is a common, consumer-friendly signature that has a focus on the lows and highs. If done right, the signature is very musical and fun while maintaining quite a bit of accuracy. The PowerJax has it done right.

The low end has a tilt towards the lower octaves. This leads to a beautiful rendering of the sub-bass and its texturing down low. The texturing, and bass as a whole, has a nice solid texture behind it. The lower bass has a nice strong impact behind it that is strong, and with a bit of force. The impacts, however, remain extremely tight and controlled due to the quicker decay. This leads to a strong punchiness midbass.

In the midrange, we find that the focus is on the upper-end of the spectrum. This leads to a bit of detail loss in the lower midrange as well as a loss of detail retrieval down here. The vocals have a strong edge behind them and are filled with energy caused by the strong focus of the upper dynamics. While doing great up high in the vocals, they tend to lack a bit of lushness to them. Midrange clarity as a whole stands to be a strong point of the headphones.

The treble, like the midrange, has a focus on the upper ranges. The upper treble is vividly detailed, but a little edgy and a little strong at times. Separation is ample, but could improve. The lower treble has a nice strong presence to it and is detailed fine. It, however, doesn’t have the extension it needs due to the quicker decays up here.

Audio: ★★★★½


The build quality of Atomic Floyd headphones proves to be some of the best I’ve encountered as a reviewer. In the past, they’ve nearly missed the mark of perfect build with a tiny complaint. The PowerJax come with a rubber carrying case similar to the one that came with the SuperDarts. The case isn’t as firm as the one with the SuperDarts, but will do fine as a case.


The materials Atomic Floyd uses for their housings is one of my favorites as it looks absolutely beautiful. The steel used, however, also remains very strong and rigid which keeps me confident in the IEM’s build. Protruding from both housings is a nice strain relief that is strong and angled. So, the housings aren’t only beautiful, they are also very strong.


Connected to the strain relief is the upper half of the cable. Like all Atomic Floyd headphone’s I’ve tested, the upper half is a little thinner than the bottom, but it is Kevlar reinforced. The lower-half of the cable is braided beautifully to give them an additional texture and feel, but also keep the cable strong. The cable rarely tangles, but does have a bit of memory effect.


The headphone jack has been the area where Atomic Floyd just barely missed the mark in the past. Well, its no more. The headphone jack has been changed from a straight jack to an angled one at 90 degrees. It’s encased in rubber that is stiff, but also flexible enough. The Atomic Floyd emblem sits at the end of the rubber barrel.


Build: ★★★★


The Atomic Floyd PowerJax are actually quite comfortable in the ear. When worn, the housings sit securely, and comfortably, inside the ear. That said, they’ll stay in place just fine. Included with the PowerJax are 3 pairs of silicone, hybrid tips to ensure a proper seal and fit. The PowerJax were designed to only be worn down, and wearing them up is not an option. Despite using the thinner cable up top, the IEMs can be a little microphonic at times.


Comfort: ★★★★½


The Atomic Floyd PowerJax come in at 150 dollars, half the price of their flagship SuperDarts. The PowerJax are actually a great IEM at this price point and really are right where they need to be. The sound quality is definitely priced well, albeit a little competitive. The look and feel of the IEM as a whole is very solid indeed and worth the buy. A remote and mic is included for a supporting iDevice.


Value: ★★★★½

Final Thoughts

Atomic Floyd has always seemed to impress me in some way with the sound signatures they provide with their products. The design scheme they use is very classy, but also unique in its own way. The PowerJax are a really great IEM, not just to look at, to listen to.

I’d like to thank Atomic Floyd for the product sample.
