Rock Jaw Alfa Genus V2 Detailed Review

Below, you'll find our detailed Rock Jaw Alfa Genus V2 review. You can skip to a specific part using the quick navigation links below.

Packaging and Accessories

Usually, the packaging of in-ear headphones is horrible.

Many IEMs just come in some plastic that you're meant to throw out after opening them.

I think the packaging is important, as it is the first impression you get when looking at a pair of headphones.

Luckily, the Rock Jaw Alfa Genus V2 has a great packaging for a pair of IEMs.

It feels solid, and the V2s are well protected by foam.

The V2 comes with quite a few accessories. They are:

  • 6 sets of additional ear tips.
  • A shirt clip
  • 3 interchangeable tuning filters
  • A soft carrying bag

I like that they include so many ear tips, as having a proper fit is vital, and the shirt clip helps to improve the level of comfort.

The most interesting accessory is probably the interchangeable tuning filters. They let you change the sound signature of your headphones. I'll have more to say about them later.

The carrying bag is soft, which has its pros and cons.

The good part is that it is small and very convenient to carry around.

The bad part is that it doesn't offer as much protection as a hard carrying case does.

Build Quality and Design

Put mildly:

The Alfa Genus is easy on the eyes.

With the aluminum casing and silver linings — they're a beautiful pair of in-ear headphones.

The casings are robust, and the cable is very solid. It's a tangle free cable that does its job well. I've never had any problems with knots, which is a huge plus for IEMs.

It terminates in an L-shaped jack. Personally, I prefer the straight jacks, but I've heard several people argue otherwise. I suppose it's just a matter of personal preference.

Located on the left earpiece cable is a microphone with a single button. This button can be used to answer phone calls or to skip tracks. Keep in mind that you cannot adjust the volume with this button.

I know that it's a deal breaker for some people, but I didn't have any problems with it. I hardly adjust the volume when I'm out and about anyway.

Moving upwards, the cable connects to the earpieces with a silver strain relief. It's rather robust, and it is in perfect harmony with the rest of the earpieces. Rock Jaw really did a great job designing the V2.

As I mentioned before, the housings are made of aluminum, which makes them extremely durable.

Behind the tips is the interchangeable filter. There are three filters:

The default filter that is installed is the chrome one that enhances the bass.

There are two additional filters, one black, and one gold. The gold filter is natural, which means it doesn't color the sound. The black filter enhances the treble which, depending on your taste, could work very well.

Comfort, Fit and Isolation

The number one factor to comfort with IEMs is the fit. If you can get a good fit, then you're all set.

The Alfa Genus comes with several different tips, so getting a proper fit shouldn't be a problem for most people.

The cable is slightly heavy, which can impact the level of comfort. Luckily, the shirt clip takes almost all of the weight and reduces the strain on your ears.

Overall, the V2 is a very comfortable pair of headphones.

They don't offer very good isolation, though I don't think this is the main purpose of these headphones.

If you're looking for a pair of headphones specifically for noise isolation, then you should probably look elsewhere.

That being said, they provide a decent amount of isolation. If you aren't listening in very noisy environments, then you should be perfectly fine.

Sound Quality

This is probably the most interesting section for the Alfa Genus. As I mentioned above, they come with three different tuning filters that alter the sound signature.

They're quite easy to change. It doesn't take more than 30 seconds to unscrew them and replace the old one. Be careful not to lose them, as they're quite small and difficult to find.

The Chrome Filter (Bass)

Let's first look at the chrome filter. This filter enhances the bass.

Does it change it in any significant way?

Yes, it does. I was skeptical at first, but it really does enhance the bass quite significantly.

It works absolutely wonderful with bass driven genre like hip-hop and EDM. The signature is warm and bass centered.  

The problem is that the mids get slightly lost behind the bass. It's not a huge issue, as most music you will be listening to with this filter doesn't thrive on the mids and highs.

If, however, there's a considerable amount of mid focused tracks in your collection, then this filter will not be the best choice. ​

The Gold Filter (Natural)

Which brings us to the gold filter.

The gold filter provides a neutral sound signature. The bass isn't as overwhelming as with the chrome filter, and the treble isn't as pure as with the black filter.

It is, however, the perfect middle ground. If your music collection isn't dominated by a specific sound signature, then this filter will be great.

You won't have to be constantly changing the filters to suit your music. I'd say that the gold filter is best if you've got a very versatile collection or if you don't like to color the sound signature.

The Alfa Genus with the gold filter comes close to perfection for me. ​

The Black Filter (Treble)

The black and chrome filters are the two ends of the extreme, with the gold filter in the middle.

This filter enhances the treble. It makes the high-end tones exceptionally clear. If you enjoy a good treble, then you'll absolutely love this filter.

The problem with it is that it doesn't work very well with genres that aren't treble heavy. The bass becomes very weak with this filter. That is, of course, the idea with the filter, though.

It also alters the sound in a sort of sharp way, meaning that it's easier to get listeners fatigue.

These filters are a fascinating feature. I always recommend purchasing several headphones, so that you can dedicate them to the tasks they do best — the Alfa Genus reduces this need significantly.

With only a single pair of IEMs, you can essentially have three completely different sound signatures.


The Rock Jaw Alfa Genus V2 provides quite a bit of value for the price they're asking for it.

Not only is the quality of the headphones top notch, but you essentially get three different headphones when you buy the V2.

I'm very impressed with how much the tuning filters alter the sound signature. I can see myself switching between filters when I expect to listen mostly to bass or treble heavy tracks.

These in-ears should last you a long time, as they're incredibly durable.

Overall Score

How Rock Jaw Alfa Genus V2 Compares

Let's look at how the Alfa Genus V2 compares to some other headphones.

Rock Jaw Alfa Genus V2 vs Fidue A71

The V2 and the A71 are both quality headphones, but if I were to recommend one over the other, then I'd recommend the V2.


There are a couple of reasons.

The V2 has an arguably better sound quality, and with the three tuning filters you can personalize them quite significantly.

Additionally, the V2 is more comfortable than the A71. They are designed differently, the A71 is worn over the ears, but they are also a lot heavier.

All of these factors point to the V2 being a better pair.

Choose the V2 When

  • You want a versatile sound signature
  • You want a high level of detail
  • You want a comfortable pair

Choose the A71 When

  • If you mostly listen to bass genres
  • If you prefer a dark sound signature
  • If you don't worry about micro details in tracks

Rock Jaw Alfa Genus V2 vs Brainwavz S0

The Brainwavz S0 is for the bass head. You should only be considering them if you only listen to bass heavy music.

The V2 is again the better headphones. The sound signature of the S0 is rather similar to the V2 with the bass tuning filter.

That's one reason that the V2 is a better choice for most people, as you can get a sound signature that is similar to the S0 just by changing a tuning filter.

The V2 also has a lot better clarity than the S0, and its build quality is more durable.

Choose the V2 When

  • You want a high level of clarity
  • You want a durable build quality
  • You listen to several different genres

Choose the S0 When

  • You ONLY listen to bass heavy music
  • You want a cheaper option (not by a lot, though)

Should I Buy Rock Jaw Alfa Genus V2?

There are a couple of things to consider before buying the Alfa Genus. The first being whether or not you want the ability to change the tuning filters.

To some people, changing the tuning filters will just seem like a gimmick. If you don't think you'll be changing the tuning filters very often, then you could argue that some other headphones are a better choice.

Nonetheless, even if you decide just to use the natural filter, the V2 is a great pair of in-ear headphones.

While the V2 isn't expensive, there are cheaper options out there. So you should ask yourself if you're willing to pay a little extra for the extra quality that the V2 provides.

If anyone is on the fence about the Alfa Genus, then I recommend you given them a shot. They're a fantastic pair of headphones!

Conclusion of Our Rock Jaw Alfa Genus V2 Review

Before trying them out, the interchangeable tuning filters seemed like a gimmick to me. I didn't think they'd alter the sound signature in any significant way.

To my pleasant surprise, they do an absolutely fantastic job of altering the sound. The bass filter enhances the bass substantially. It is perfect for anyone listening mostly to bass genres.

The natural filter is great for people who enjoy a sound signature that isn't colored. It's useful for editing and producing. It should be your default filter if you listen to several genres.

Finally, the treble filter is fantastic for the high-end tunes. Acoustic genres shine with this filter, though it can be a little bit fatiguing.

The build quality of the Alfa Genus V2 is great. They're very durable and should last you a long time.

Overall, the V2 is a good pair of in-ear headphones. With the good sound quality, the versatility, and the durable build quality, anyone who purchases the V2 will certainly be contempt.
