This seems a new headphone....or just TYGR 300R? Source:https://global.beyerdynamic.com/100-years-beyerdynamic

Wider bandwidth "maybe" means lower TIM,Transient Intermodulation distortion. But a switch about some term True Transient Technology which seems more like marketing language.

It's just use the specific baffle/cabinet resonate as simple acoustic filter, an calculated design.

Ok, a 3khz resonator, just similar to K812.

No impedance or phase curve?

So the TTT switch is simply a low pass filter? oh....

You need more gain than to drive K812 properly . This is K812's FR with low gain K812's FR with high gain amp

K812 is truly the statement headphone by later AKG, but..... 1. Lacks balanced connect option, when most "hifi headphone amp" go for balanced, its become a problem. 2.Head-Fier actually not so like so call "neutral" timbre, in fact, most of us prefer slight rising treble for transients and...

It seems a simply design reduce airflow noise and backwave guider/smoother.

Seems the center dome takes more part than 812's ,and bigger bass port. Different corrugations around the ring part. Interesting, so why focus on low THD marketing language? This would makes the measurement gangs got goods on this headphone.

Seems interesting enough, maybe a Zobel network?

Yeah, there are so many Hi-End headphone nowadays, So what's made the composer different/special? I don't think this is merely audiophile non-sense.

As a headphone (luxuries) price tag 2500 euros, Austrain Audio really need some sales point / marketing language. At least show some exploded view of the 49mm driver, and try to explain what's "True Transient Technology",and why it matters.

Remove the absorber disc would ruin the tone of 3rd. Just take care of earpad, that't is the really problem need too long time aged. (remove earpad and you will see the bass-reflex vent, that's the key point.)

As a new Evo user, I see the qobuz X etymotic special offer page , does someone knows where i can find the offer code? Thanks.
