Pros: Price vs Performace, High quality build, Sound Signature I absolutely enjoy

Cons: Currently using a tupperware container for a pouch

Price – Approx $73 Canadian

 

Preface : I am just a typical guy / father of three young children who loves music and has been a member of the head-fi for approximately 4 years. I have no background in music and work in IT for my career.

 

I have been fortunate enough to own some TOTL headphones / IEMS over the years (HD800, LCD2.2, T1, Heir Audio 8A Customs, etc…) and the words I type are my own personal opinion of a product that was given to me for the intent of evaluation.

 

Rock Jaw has sent me two set of head/ear phones to evaluate: The Alfa Genus and the Acero.

 

This review will only reflect my honest thoughts on the Alfa Genus since they are the only pair I have concentrated on to this point in time. I have used the Alfa Genus for one week on a daily basis in my office with no prior burn-in for 3-5 hours per day.

 

Let’s begin….

 

The thing I thought immediately from the moment I opened the cardboard box and viewed the Alfa Genus was simplicity. I am not saying that simplicity is a bad thing at all, just the opposite actually. I literally had these earphones stuck in my head one minute after I had the shipping box opened. 

 

-The cable is not removable, but in this price range I certainly wouldn’t expect it to be. The actual cable is thin, but a coating on the cable gives it a solid feeling and makes me feel that it will withstand some abuse if that’s how you tend to treat your equipment. I am happy that the cable is terminated with a 90 degree jack, but I guess that comes down to personal preference.

 

-The Alfa Genus came with two sets of filters which can be used to customize the sound to your own personal preference (pretty cool feature IMO). I tried both initially and knew right away that the ebony filters were NOT for me. This entire review will be based on my using the silver metal filters.

 

-The casing on the earphones seems extremely well put together and solid. They are quite light however and they seem to disappear in my ears in a very short period of time. One thing I would prefer is that the L and R were printed in black opposed to white on the metal since it takes me a little bit of effort to differentiate between the two.

 

-I can honestly say that I tend to stay away from IEMs due to what I thought was a personal problem of having monster large ear canals which has caused me grief for years on getting a good / solid seal with earphones. As we all know, no seal…. No bass. When I received the Alfa Genus, I immediately pulled of the medium tips provided and replaced with the large tips (3 pairs of tips come with the AG - sm, med, lg) I was happy to see that seal was not going to be a problem with these earphones. The tips that come with the earphones (although not a wide selection) are what I consider to be high quality.

 

Sound evaluation:

 

I have used the following setup to evaluate the sound of the Alfa Genus over the past week.

 

Samsung Note III  > OTG cable > Dragonfly 1.2 > Alfa Genus

 

I have used USB audio player for the first half of my evaluation week playing a selection of lossless flac playing directly from my phone. For the second half of the week I used Spotify (extreme quality streaming) and also used Gizmo which has the ability to access my home library and transcodes to 320kbps over an LTE connection.

 

I only evaluated with music that I actually like and listen to a daily basis. Typical music includes Anne Akiko Meyers, Christina Perri, Bob Marley, Michael Jackson, Foo Fighters, Of Monsters And Men, Brandi Carlile, Jack Johnson, The Civil Wars, Mumford & Sons.

 

I have no desire or interest to describe the minutest details for a list of songs which I probably couldn’t do accurately anyways. I don’t believe I have the golden ear skill and accurately give a detailed written representation of what I am actually listening to.

 

If I had to sum this sound evaluation up in three words: Detail, Bass, and Fun.

 

I am still surprised when I put these little bullets in my head, how good they sound to me. I have spent double / triple the price on earphones in the past and have not had that enjoyment feeling that I am getting from the Alfa Genus IEMS. I am listening to Guns & Roses - “Patience” as I type and there is a feeling of soundstage that I get that is wider than I am used to for IEMs.  Instrument separation is impressive to me and everything just sounds right to my mind.

 

Sound is very detailed to me without sounding shrill or sharp, I have noticed zero sibilance during my time with these.

 

Bass, man the bass is wonderful in my opinion….. It seems to hit low without being sloppy or over-exaggerated. It also does not seem to kill any of the yummy detail these earphones can produce.

 

Would I actually buy these for MSRP ?

 

I would buy these without a doubt. These are absolutely impressive to me for less than $100. I will say that I am now a fan of at least one rock jaw product and would recommend the Alfa Genus to anyone looking for top notch sound quality at a totally reasonable investment. I literally can’t wait to try some of the additional products (Kontrol in particular) in the Rock Jaw IEM lineup.

 

Thanks for the opportunity and sincerely,

Darren Crane
