Rock Jaw Alfa Genus V2 Headphones

High performance earbuds with three different tuning filters

Rock Jaw Alfa Genus V2 Headphones

Rock Jaw Audio

The Alfa Genus V2 by Rock Jaw Audio are in-ear headphones that come with the added luxury of audio tuning filters. Having this option gives you a great advantage when it comes to getting the best listening experience from your digital music. Incidentally, if you don't know what these 'tuning filters' are, they are small components that screw into the main headphone housing enabling you to change certain sound characteristics.

If you like a lot of bass in your music for example, then using a filter that is weighted towards lower frequencies will boost this part of the audio. Typically in-ear headphones that use a tuning filter system (such as Trinity Audio's Delta) come with bass, natural, and treble filters to cover different listening requirements.

In this review find out how well the Alfa Genus V2 headphones perform and whether the different filters make a real difference to your music.

Style And Design

A lot of earbuds these days tend to be made of cheap plastic. However, seeing that the Alfa Genus V2's are positioned as high-performance headphones it's nice to see they are also constructed with good quality materials too.

The driver housings, for example, are made from light-weight aluminum. They certainly feel light and their polished look adds a nice visual appeal too. The strain relief on each of the housings is also made of metal which overall makes them a solid build.

The filter stems are designed to be screwed into the earphones and this design makes it really easy. On average it takes about a minute to change both tuning filters.

You get a good selection of stylish ear tips too with the Alfa Genus V2. There are three different sizes of silicone ear tips (small, medium, and large), two sizes of memory foam tips (medium and large), and one pair of double flange silicone tips. These are all well designed and are comfortable to use too.

Audio Cable

The headphone part is obviously important, but how about the cable?

Rock Jaw have used a rubber outer sheath to protect the 1.2 Meter cable. It's actually quite thick compared to other cable designs we've seen and doesn't tangle that often either. It flexes easily and feels robust enough to deal with a good amount of bending etc.

The version I received also included a remote / mic button. This worked well in not only talking calls but also controlling the usual music playback functions. The company also sell the Alfa Genus V2 without a remote / mic, but the difference in price is only a couple dollars. With this in mind, it might be prudent to opt for the better version anyway even if you don't think you'll be using it right now.

To keep the cable safe while not in use, Rock Jaw also include a small draw-string bag. This is handy and just about accommodates the cable. As an added bonus you also get a lapel clip for attaching a shirt etc. so your cable doesn't snag on anything. 

The Tuning Filter System

As previously mentioned, the great advantage of having in-ear headphones that come with tuning filters is that you can change the way they sound. This is perhaps the biggest selling point of the Alfa Genus V2's. They're easy to swap over too. Once the ear tips are removed it's just a case of unscrewing the filters that are already in and swapping them for another pair.

The system is very well designed and works well.

Rock Jaw Audio provide three different tuning filters which are different colors. This is so there's no confusion if you manage to get them all mixed up. The filters you get are:

  • Silver (bass) The Alfa V2's come with these already fitted. These give you more bass than the others while promising to preserve detail in frequencies higher up.
  • Gold (natural) If you prefer a flatter experience with no particular emphasis in any frequency band then the natural filters are the ones to use.
  • Black (treble) Maximizing top-end frequencies is sometimes necessary when listening to some music genres. Bass isn't important in this case so Rock Jaw's black filter aims to eke out as much of the mid to highs.

Audio Quality / Tuning Filter Comparisons

We've so far established that the Rock Jaw Alfa V2's are well designed, look good and come with the added advantage of tuning filters. But, how do they actually sound?

In order to make sure the test was well balanced, we listened to a wide range of different genres from bassy tracks all the way to orchestral pieces that had more high frequencies than anything. A comparison of the tuning filters was also performed in order to quantify how they differed.

All the filters come color coded so it's easier to tell them apart. The first to be tested was the silver ones. These are already fitted out of the box and are designed to enhance bass. They're quite impressive in boosting the lows without overdoing it. Drums sound nice and tight and other bass sounds are well defined. Higher frequencies aren't drowned out either which makes these filters perfect if you like genres such as pop, dance, and anything else where bass is essential.

The Gold filters were the next to be fitted. These give a flatter response. Bass is toned down, but there's still a surprising amount. The natural filters give a well-rounded sound with a nice detailed stereo filed

The last ones to be tested were the Black filters. If you like treble rather than bass then these give a lot of clarity in the mid to highs. However, the difference is quite subtle compared to the naturals. That said, you can hear the difference. The upper-mids are nicely enhanced while the highs aren't too wispy.


Rock Jaw Audio have done an excellent job in designing the Alfa Genus V2. Not only do they look good, but the level of audio detail is excellent too. Considering you get high-performance headphones complete with a tuning filter system, the asking price is a stellar deal.

If you want to step up from budget in-ear headphones then the Alfa Genus V2's are a great option for getting the best out of your digital music.
