Measurement of output power
Why the subsequent effort now? I had to realize that I couldn't bring any of my headphones used here (Beyerdynamics T1, T90, Amiron Home, MMX300, Meze 99 Neo, Sennheiser HD 800) even close to a full control. At the latest, my foreboding was no longer alone in the hallway when I read the specs.
Yes, it was a bit louder than quiet and yes, you can play with it well and comfortably. But pressure is a little different and it is always reassuring if you also have the necessary technology to prove what you claim to be resilient with real data and not only to feel and listen verbally.
But let us just come to the bare facts, because they are at least backed up by measurements. First I start the test with 32 ohms. I also tested a 32-ohm headphone instead of the ohmic resistance, whose impedance at 1 KHz exactly matches the 32 ohms. With the measured 0.68 Vrms or 14 mW you don't pull sausage from the plate and with headphones, whose sensitivity is less than 100 dB at 1 mW SPL, you don't need to start here. The Beyerdynamic MMX 300 sound empty, powerless and sloppy.
And even if all volume controls are at maximum (game, amplifier), the punch is simply missing. It doesn't distort anything, because you're still a long way from the full level. If the sensitivity is 102 dB at 1 mW or higher, then it may all work, but so? The product range becomes quite manageable due to such preconditions on the transducer. Take, for example, the Sennheiser GSP 600 as their gaming headset at the top of the acoustic food chain, then its 112 dB SPL at 1 kHz and 1 Vrms at 28 ohms only look compatible at first glance.
Because with 0.65 Vrms at the amplifier output, it is not even the basic condition of one volt for this specification fulfilled. The GSP 600 is not bad, but will only be able to play out its qualities to a limited extent on the GSX 1000. But it is a mystery to me why one is already so badly wrong with your own product combinations. I don't measure my lab measurement at sound pressure now, but with approx. 106 to 108 dB at the top is still very far from the target, even without a specially calibrated measuring workstation.
At 250 ohms, it doesn't look any better, on the contrary. With 0.78 Vrms and a whole 2 mW per channel, you're pretty quick to get to the end. You simply notice that no separate amplifier amplifier amplifier was installed here.
From 600 ohms you end up with a milliwatt and 0.79 Vrms, but then it doesn't get any less. Except that this will be enough for nothing. The bottom line is that this entire test process generates a certain disappointment, which proves once again that a beautiful face and a great name alone do not have to guarantee for the ideal partner. As a Friday night acquaintance, that may work, but in the long run? Audio products are like spouses: you have them (mostly) for a lifetime. Ideally, of course.
Subjective hearing test
The frequency range, on the other hand, is appropriate and I have below 5 Hz or above the 30 KHz, because you then quickly slide into the voodoo wonderland. The measuring range is sufficient and I have not noticed any abnormalities – as long as you equalizer and 7.1. Disabled. And also with my own ears and not only with the measuring equipment. This can then be positively recorded on the credit side.
The equalizer profiles, on the other hand, are very arbitrary and even partly superfluous for my taste. The music mode is still most useful if you orientate yourself to the bathtub mainstream and like this type of game. For a chill-out at the fireplace with quiet music, I still like it, but the rest is, well… The e-sports mode without bass and scurrying upper middles, on the other hand, is a mental strain. It may be a suitable symptom control as compensation for nasty headphones, but it sounds rather oblique.
I can even understand the argument with the bass in places, but why everything has to buckle, as if you were to turn a hit bard's neck unfavorably, does not open up to me. The story mode sounds even more useful. Because one thing must never be forgotten: location and spatial positioning of the sources starts with the mechanical transducer, the rest is only Botox for the ears. Symptom relief instead of the fight against causes.
Without EQ you can even listen to music and enjoy classical music without any stress. Just HDR content with 20 to 30 dB dynamic range should not be tried at all. But it is advertised for gaming and there the range hardly goes over 10 dB SPL range (in terms of the 85 dB feel-good pressure, which one generally pretends)
Summary and conclusion
Yes and no. If you are looking for a very successful virtual surround fun and have a headset with 32 Ohm impedance and a sensitivity of over 110 dB / Vrms, you are welcome to strike if you like the beautiful look and pleasant functioning of the touch control. So you will be right here, even if the street price from 150 euros is already somewhat generous. If you want to be beautiful, you have to suffer and you also pay heavily for the fire.
On the other hand, those who are looking for pure performance, are audio-visually influenced by leisure music or are at least as important to the unfiltered enjoyment of music as the instinct to play, are definitely on the wrong platform. The Sennheiser GSX 1000 is not a puncher, but rather a smooth-gelled beauty with an exciting outfit and a certain aura of the luxurious.
But for a deeper love this is nothing, at least not with me. Of course, everyone can see this differently, because I am not the final instance either. And certainly not a hardcore gamer. It may be that i didn't quite understand the product, who knows. But it looks beautiful and makes use of easy. at least. Therefore, no thumb pointing downwards. But for an award, there is simply not enough performance.
