Beyerdynamic to launch new top headphone at IFA -- called T1 - Page 7

I believe the "7dB louder " refers to more wide dynamic range

not more volume

No. The 1.2T is the magnetic flux within the voice coil gap and would be considerably less where your brain is. Its also a static magnetic field, and opposing magnetisms would reduce eachothers respective intensities (because they are like charged) which would reduce the impact on the head (and have zero on a mono signal at half-way between the two cups).

The issue with cell phones causing tumors etc (highly unjustified claims, btw) is that the magnetic field is assymetrical. Still, they dont have much.

Modern MRI equipment has about 8 tesla in an assymetrical field which multiplies and causes change (resonance) in order to provide the image. There are "issues" apparently associated with this, but compared to this the T1 is rather modest.

Not to mention there is research that shows neuron-growth is increased in rats by the presence of a magnetic field so yay for propaganda.
Mobile phones get the brunt of the medias "magnets poison your body" fiasco, and as such are lowering their emissions to a. reduce the flames and b. maintain a larger battery life.

Great time to be alive headphoners....

Oh Yay...600ohms...built for "Funitor" Phonitor

sure we do... but presentation does play a big role in the perception of things. HD800 presentation was great, nice pics and informative texts that where not too long. Looks like they care about how it is presented to us. That got people drooling.
T1 wall of text is almost impenetrable and thus not as effective, but I'm sure there will be better marketing after the show.

well, why does only Ultrasone care?

ULE-technology

they even got tons of german PDF's where it seems clear that regular headphones really send a hell lot of EMI straight to your brain and ears..

I spend a lot of time w/ headphones on my head, I hardly ever use cellphones coz I hate them...and I end up w/ far more brain frying frequencies than if I were using one!

and now, they make super-magnets! I can't stand the Ultrasone sound, so I guess I'm SOL on this one

Time to don the tin foil hats before this government headphone radiation takes over my mind.

Still a lot of "Sennheiser" in the HD800. Too much for me as a 'beyerphile'.

Ultrasone uses this for marketing purposes only, if you ask me. If it was really that bad some had most probably found long before.

MRI uses an alternating field, not static.

The T1 even needs less current then other phones for the same volume level. Less current results in less megnetic field induced by the voice coil.
But thanks to the strong magnet you won't sacrifice overall volume level or dynamics.

I wasn't necessarily speaking of transient response but greater frequency range ad cleaner frequency reproduction (=less distortion). It's the same reason for a woofer being unable to reproduce high frequencies or distort a lot when forced to do so. They have too much inertia to be able to follow a faster changing signal, resulting in a roll off to higher frequencies.
To reproduce higher frequencies lower the weight of the diaphragm and/or strengthen the magnets. A good mid driver with a lightweight, yet stiff diaphragm and a strong magnetic system is able to reproduce higher frequencies with lower distortion then a heavier one with weaker magnets.
And headphones use single wide range drivers so being able to (theoretically) reproduce higher frequencies with less distortion with the same mass needed to reproduce a good bass can't be a bad thing. Especially since the heights have always been problematic on beyer. It got better with the 600 Ohm system but these still based on the same design as the 250 Ohm.
So I'm putting much hope into this newly designed 600 Ohm only design.

Transient response equates to frequency range. A stronger magnet doesn't affect it, just increases efficiency. Which of course can have a positive effect on the distortion behavior of the connected amp.

But as stated, Beyerdynamic's approach obviously is to use a strong magnetic field for being able to reduce the voice-coil's moving mass without sacrificing efficiency, which is a good thing.

These have very little to do with each other.
Read this for an explanation of transient response.

Why don't you guys take this over to the Sound Science board. Can't we just salivate over the potential of these new headphones?

Because everything we have right now is theoretical, there's actually not much else to talk about. We are actually picking them apart before they were even put together.
There is that too of course.

Salivating, drooling and all that kind of needing to wipe my mouth type stuff. I kind of wish I never found this site!

You must know that you can perfectly calculate frequency response from a pulse response – and vice versa. It's all in the transfer function (→ signal theory).

The sound pressure level is 102 dB (1 mW / 500 Hz)
The maximum SPL at 126 dB (300mW / 500 Hz)

So that's the "7dB louder"

....whew , but why 500Hz? It's about loudness EQ or something?
