beyerdynamic t50p

Grabbed some interesting information concerning positioning of T50p on beyer´s website:

Looks silly? Due to the small size of the earcaps (thx to portability...), it seems that it might need some extra attention to get a tight sealing (also with my ears, although being used to wear headphones), but it´s worth to do. Sound is perfect now, and reduction of environmental noise is improved a lot.
 
Would have been glad to receive such kind of information at an earlier stage...

I have looked around on the forum, but please forgive me if I missed it: Does anyone have any considered impression for the T50P versus the P5? I own the P5, and I'm out of my two week window, but I could always return them. I find the P50 has a really scooped/compressed midrange that makes listening to music (indie rock, jazz, rap) really unpleasant. I have all good source material (V0 ripped from CD), and I listen from my iPhone. Some things sound enlightened on the P5, but most thing sound kind of garbagey.

The P5 has a noticably recessed treble.  The T50p has a slightly elevated treble.  This is the most significant difference.  The P5 will sound warmer, but for me it was wooley and too soft.  The t50p is cleaner, but can border on edgy.  For me the t50p is much, much better overall.

Just recently I spoke with Beyer SE and managed to send back my t50p to them for refitting of the clamp (headband). They took the unit to their R&D in Germany and had it redesigned with a much tighter clamp than the first initial production run.
 
This was Philippines, Singapore, Germany and back again in about 5 weeks total turnaround time (would have been 2 weeks but my pick up guys timing was longer).
 
I have to say the redesigned headband and clamping pressure makes a big difference. The isolation has noticeably improved giving a warmer sounding treble with a lot of the initial edge taken off. The bass response is improved with the tighter clamp with less leakage without taking away from any of its initial strengths.
 
Its USP is still a beautiful detailed treble presentation but it is now has a much better mid and bass response.
 
I have to say well done to Beyer SE for this. Apparently the next production run will have this new improved clamping.
 
Our own forum, www.headphiles.org has a number of veterans also and they have remarked this new version is definitely an improvement on the stock original version

... it's stated in the accompanying manual too ...
 

snip
 
Just discovered that these can create a huge magnetic field ... I hang them up over a bar so that they can swing freely.
I did this to measure dbA and dbC with an decibel meter so to get an idea at which point I will damage my hearing ability.
(90 db is that much loud ... I couldn't stand hearing that for more than some seconds ...)
 
I could swing the phones easily with this decibel meter without touching the phones.
First I thought maybe it's to do with the meter and I tried again with my door key.
Same thing.
So I could swing the phones with the key 1 to 2 cm away from the cup.
If I got too close the key would even pull the phone and make contact and hold it (not strong though!)...
 
Is that normal ?

As a mechanical wrist watch fan if the magnetic field is as strong as you say they be careful if you wear mechanical wrist watches. a field that strong can effect the timing of a watch and if that happens it has to be taken to a watchmaker to de-magnetize it! The sound like nice headphones though!

It's absolutely true and no joke! I just did it again. Perhaps I should make a short movie and post it via YouTube ...

Well usually I wear my wristwatch around my wrist and not around my neck

(But perhaps they should put a warning inside their manual for people wearing a pacemaker, I mean, they're also made to rest around your neck ...)

Ahh yes but what do you use to put your headphones on your head! Even a short burst of strong magnetic power such as putting headphones on your head is enough!

So you should put them on and off  with the music off ...

That's a good point! Are the magnets only energised with power or are they always on? I guess this is like un-shielded loudspeakers. I have known a couple of friends have their watches magnetized by them!
 
Of course the answer would be either go with quartz (which may still get magnetized but once away from the field usually recover to normal timekeeping) or get a watch like mine, Milgauss which is resistant to 1000 Gauss due to it having two cases, the movement is protected by a soft iron Faraday cage!
 
Addendum!
I just found a site that gives the values. Now, I am not scientific at all and am well known for reading this sort of stuff wrong but when I punched in 1.2 tesla which is I think the amount the beyer tesla phones have it came to 12,000 Gauss so even my Milgauss would get magnetized..Yikes!
 
Here is the conversion site.

Just to avoid any confusion: The magnetic flux density of 1.2 Tesla is achieved in the air gap inside the driver only.
Of course, nearly all the magnetic power is focused in the air gap, and the outside stray field as low as possible (since any stray field would reduce efficiency!).
 

 
By the way, the outside magnetic flux density of T50p is less than 0.015 Tesla, so don´t worry about magnetization of watches...

Thank you so much for clearing this up! To use an English expression, Right from the horses mouth! Out of interest what is the outside magnetic flux of the two other tesla models?
