Beyer T5P Frequency Response and CSD Waterfall Plots.
This one's for you Whitney, you hater!

I would love to try modding those.
-
I didn't even bother listening. For Beyers, standard procedure is to measure first, listen later (if at all)
-
I think this is the first time I've seen ringing happen at a different frequency between left and right drivers. I know I've seen varying degrees of severity, but the left one is at 4.5k and the right is at 6k. Looks like there are corresponding peaks in the FR.
-
Sweet mother of God!
-
Oh my! Didn't notice!
Not the best journalistic or scientific practice (I am neither a journalist nor scientist, although I do consider myself an "advanced weekend hack"), but I have to be totally honest:
- I didn't bother listening.
- I didn't both looking the graphs.
This is the first and probably only time I've ever done this with any headphone sent to me for measurement.
-
I really want to see what they are doing differently between the T1 Tesla and the lower end Teslas. They still have the honking magnet I presume or is it just brand image now like having a 'Hemi'.
-
Hmm, I wonder if I have a defective one. Other people seem to like them a lot: http://www.head-fi.org/products/beyerdynamic-t5p/reviews (http://www.head-fi.org/products/beyerdynamic-t5p/reviews)

Hard to say. I was actually most curious about the T5p thinking it had potential.

And people always wondered why I never liked Beyers.
For years people would offer them up at meets and I would politely decline. My ears must have been telling me something right.... :D
-
I still want to hear the DT48, DT250 and this T5p.
I find it hard to believe the Nazis conquered Europe w/ just treble peaks.

The sharp 5k and 7k dips on Tyll's graphs are severe ringing. Sharp dips like that on his measurements are almost always ringing. Measurements here show this in a more obvious way.
Also, what up with that seriously high level of distortion, even at 90db, in the midrange?

Lol, I finally have something for my HF sig.
-
You'll get a lot of karma points for that one.
I think they may have chased all the good engineers out of Europe. We got the bomb and they got the treble peaks

Ah....the Tesla drivers must be using Heavy water. They'll never learn.
-
I want to borrow a pair of these to write a review. That would be fun :-)
-
That's hilariously bad. Oh wait, people are getting ripped off, so I guess it's not THAT hilarious. Just kind of hilarious mebbe?
-
Also remember that these are kiteki's favorite full size headphones...
-
Here's Kiteki's review of the T5p. http://www.head-fi.org/products/beyerdynamic-t5p/reviews/6707 (http://www.head-fi.org/products/beyerdynamic-t5p/reviews/6707)
I'm not posting this to make fun of him, but because it makes it clear why he feels so threatened by measurements.
-
He liked the T70 too, though not as much as the T5p. I thought it was very nice (though pretty bright...) right up until something hit the narrow ringing in the treble. Then there was an explosion at the consonant factory.
I wonder if he likes his CSDs full of sharp ridges or something? ???
-
Kiteki does seem fond of very razor-sharp sound. One of his favorite IEMs in the MDR-EX700. I actually like the EX700 quite a bit myself, but I'm not going to try to invalidate objective measurements just because I happen to like some pain now and then.
-
It's possible that he likes that sound. Some people do.

LOL! ;D
It's good to understand where his attitude is coming from.
-
It may just not bug him. I know a lot of the headphones you guys complain about being painful don't get that reaction from me. I don't necessarily like them either though.
-
I was under the impression that the T5p was a sales dud. But this looks terrible. Really terrible. Painfully terrible.
-
Updated T5 graph. Did not apply bass comp. curves correctly. The T5p should be better sounding now.
-
Yeah now they look amazing....
-
I'm still curious about the ringing at different spots between drivers.
-
QC on their driver doping, diaphragm material, or something else must be shit.
-
There are a number of phones that have ringing in different places btwn channels. The LCD-2 is one of the better ones that comes to mind...
-
I liked the T5p I heard at RMAF 2011. It wasn't amazing, but it was seriously the only Beyer in the entire show I thought I could live with. Who knows how that one measures compared to this one. Beyer QC is about as good as a Maaco paint job.

I would agree that the T5p despite this, when I first heard it at a meet, seemed quite nice for a closed portable can. For the same reason I spent a couple of minutes looking for my jaw somewhere on the floor after I saw the resonance on these graphs...
I owned the T1 for some months as my portable can until some of its resonance got on my nerves on 'busy' passages in music - I don't even dare thing what this would be like in the long run. p:/
-
I was looking into getting these Beyers but it seems that it is not worth it? (at least not at full price...) Still, I liked the Shure 940s which seems to have LESS bass presence than these guys (and instead of a 5-7k drop it's actually elevated at the 7-10k range) so I'm not sure if that difference actually will make me hate the t5p's or not...
Also, is there really so much variation between cans on the t5p's just like on the DT1350??
Anyway, any thoughts?
-
Oh well... after all these months, got an Ok deal and bought them...
LOL!

That is actually not true. In fact they had a problem of too many engineers chasing and developing many new ideas; the technological effort was too scattered and diverse. They should have concentrated on a few good products in sufficient quantities instead of wasting effort and brain power on many futuristic projects.

... and the few good products/prototypes/ideas were?
