In the test: Gravastar Sirius Pro P9 gaming headphones - with metal case and bottle opener

gravastar-sirius-pro-post image

I do play one or two computer games - and more recently VR games - but I definitely don't belong to the group of typical gamers, I'm too old for that and the reaction time is too bad.

But the brand “GravaStar”, which is popular among gamers, still offered me the chance to test out their “Sirius Pro” headphone model. And I can't really say no to headphones... I don't really like in-ears, but the GravaStar Sirius Pro look so great that I was happy to take part in the test.

The packaging already shows that the Sirius Pro from GravaStar are not the usual run-of-the-mill headphones that you find everywhere else (Photos: Sir Apfelot).

Transparency note: I received the headphones free of charge, but this does not affect my report.

Second note: the Sirius Pro will be raffled off in my SteadyHQ group in the next few weeks. If you would like to support my blog and perhaps win one or two gadgets, you can do so at Stop by Sir Apfelot on Steady.

What’s special about the GravaStar Sirius Pro P9

When I write test reports, I've recently gotten into the habit of always providing the special features and my quick assessment right at the beginning so that you know what the product is about.

For me, the following points stand out about the GravaStar Sirius Pro:

  • There are hardly any other headphones that have such a unique look.
  • The case is made of metal and is correspondingly heavy.
  • The design is designed as if the case were a piece of military equipment that looks really worn - ingeniously done.
  • There is a triangular recess in the case, into which an LED bar is installed on one side that shows the charging status.
  • The recess can also be used as a bottle opener (photo below) – no joke!
  • The headphones have a game mode that reduces the delay between sound and image so that you no longer notice it (important when playing games or watching movies).

If I were to say in one sentence what my assessment of the GravaStar Sirius Pro is, it would be this: Do you like the design of the in-ears, you value zero-lag headphones and money plays a minor role? Then grab it.

For everyone else, it might make more sense to shell out a little more money and get the AirPods Pro or AirPods (without Pro).

“Crazy optics” – without a doubt

I mean, most of the in-ear headphones I've tested so far have tried to emulate the elegance of the AirPods or otherwise had a very clean design. The GravaStar designers have obviously declared war on this trend and are relying on a mixture of science fiction and shabby chic - and I have to say: I like it.

It's nice when companies dare to do something and anyone who has seen the chargers or other headphones from GravaStar knows that this brand is leaning way out of the window.

In any case, the design makes the fronts equally clear: someone who likes the look of the AirPods will not be enthusiastic about the GravaStar design, but they will win over all the other people as fans, and there are quite a few of them, especially in the gamer sector .

High quality workmanship

The charging case of the GravaStar Sirius Pro is - as already mentioned above - made of a zinc alloy, which can withstand significantly more than the plastic charging boxes you usually get your hands on.

I would rather not open a special case with the AirPods case - even if you could definitely do it with the edge of the cover.

But the workmanship quality is also quite decent. The earphones are of course not made of metal, otherwise they would be too heavy and too cool for your ears. But they still make a good impression.

Everything is neatly processed and even small details support this overall impression: When you put the earphones in the case, they are pulled into the correct position by magnets and start charging.

The closure of the charging case is also well solved. To open it, you press a small button on the side and unlock the lid, which is then catapulted up by a spring.

The earplugs attract each other because they have built-in magnets. This means they are immediately pulled into the correct position for charging in the charging case.

Sound quality – controversial

If you look at the technical data, the drivers in the Sirius Pro are definitely made for good sound. With a diameter of 7,2 mm, they are in the middle of the range and can therefore reproduce bass well.

Nevertheless, you can find some reviews on Amazon that attest that the Sirius Pro has poor sound. And after I tried them for the first time, I knew why: They sound bad if you don't put them in your ears properly.

With in-ear headphones, the sound is always very flat and mediocre if the earplugs are not properly inserted into the ear canal. That's why it's important to try out the silicone attachments provided and see which ones fit best.

If you have found the right ones and the Sirius Pro are properly in the eavesdroppers, then the sound will work. In any case, after the adjustment I could no longer complain about the sound.

Of course, an app like those from Soundcore, for example, would have been nice to be able to adjust the headphones more to your own needs with equalizer settings, but I usually only use these apps at the beginning and then I never open them again. In that sense, most people might not even miss the app.

Benefits

There are a few things I found pleasant about the GravaStar Sirius Pro:

  • The housing is very robust and the bottle opener is a practical thing if you can't open your drinks with the EDC knife that you probably always have with you.
  • The look is a blast if you're into that sort of thing.
  • Gaming mode has such a low latency that I could no longer detect any offset between picture and sound. And I didn't notice a significant difference in sound or energy consumption either. I'm not sure where the trade-offs were made to achieve the latency of just 65 ms, but it works.
  • Operation with wet fingers is fine, so the headphones are generally also suitable for sports.
  • Volume control, play pause, song forward and back, and switching between music and gaming mode are possible via touch control.
  • Volume controls the volume of the iPhone (not iPhone and headphones separately).
  • The latency in gaming mode is so low that I could no longer notice it. It's perfect for playing games and watching movies.

criticisms

Where there is light, there is also shadow and so I have a few points about the GravaStar Sirius Pro that I didn't like so much:

  • The price is quite high at around 100 or more euros - but I think the brand and design pay for it here. You have to be aware of that.
  • The case is quite heavy due to the metal and the design makes it quite uncomfortable to keep in your pocket. Compared to the AirPods, the Sirius Pro are a bit bulky.
  • The LED lighting is ok, but you don't quite understand what it says. The red LED flashes when the battery is almost empty, but it feels like the battery is already at 5% and the case or the EarPods almost empty.
  • The sound is ok, but not outstanding. My AirPods Pro 2 were significantly more expensive, but they also sounded much more voluminous and rounded. However, the Sirius Pro can certainly have the advantage of low latency for gaming.

That brings us to the conclusion.

I'm always impressed by the look of the GravaStar Sirius Pro Case - no one would expect it to be headphones.

My conclusion about the GravaStar Sirius Pro

I think it needs to be understood that for the same or lower price you can get in-ear headphones that sound better than the GravaStar Sirius Pro.

But you will hardly find any that come with this ingenious design and also offer a bottle opener function and gaming mode.

Therefore, my conclusion is that the GravaStar Sirius Pro is definitely something for the target group for which it was made: gamers for whom the sound is still good enough even with a “good” rating and for whom low latency and a special design arrives.

Anyone who is attracted to the design language of the headphones and doesn't want to use them to enjoy classical music can go for it. Anyone who cares less about design and more about listening pleasure should perhaps go a little further and get the AirPods Pro - or look for an even cheaper alternative.

FAQ

Here are a few more questions and answers that I found about the Sirius Pro.

Are there sound differences between the GravaStar Sirius and Sirius Pro?

The GravaStar Sirius scores with 7,2 mm dynamic drivers that emphasize the bass range. In contrast, the Sirius Pro expands the sound spectrum with Knowles Balanced Armature drivers, which ensures improved reproduction in both the low and high frequency ranges, ideal for music, films and games.

Can I use the Sirius Pro and Sirius earphones individually?

Yes, the Sirius Pro earphones can be used individually. The earbud removed first automatically becomes the main device.

Do the Sirius Pro and Sirius support touch controls?

Both models offer practical touch controls. You can control music, answer or end calls, switch sound modes, adjust volume, and activate Siri with a single, double, triple tap, or long press.

Are the Sirius Pro and Sirius earbuds waterproof?

Yes, both the Sirius and Sirius Pro have IPX5 certification, making them suitable for most weather conditions and activities.

Can you really open bottles with the case without damaging the case?

Yes, I tried it myself. The case is very stable and made of metal. And in the recess there are two protruding areas with which you can lever up the bottle cap.

  1. Ollie Men do that

    If I wanted headphones that would fall out of my ears while running and then be gone or whose batteries would constantly run out (i.e. BT headphones without a cable), THEN it would be these. I actually think it's cool. Could come from the Nostromo or even more likely from the Sulaco. :-D

    1. Hi Ollie! Yes, if you don't want anything with a battery and a bluetooth, then these aren't the right ones. But you're right about the design... it's something from Alien. This also explains the little tentacles that were pushed into my ears during testing. 😂
