How bright is an ultrasone pro 900? - Page 7

No problem.

Kees says it's impossible...

Is it an arc or a tingle? If it's static, it should just pop and equalize. If it's aVoltage leak, it would tingle and last some amount of time, maybe short amount of time, but longer than a millisecond or so like static.

.

milliseconds but it comes in pairs and sometimes a weak third tingle... then you don´t feel anything for hours... Got it after some hour once though so may be some voltage leak afterall...

I don't say it's not a problem.
I just bet my life it is not the signal wires causing it.

I don't think it would kill you...

Maybe there is a static build-up in the casing of your amp?

Maybe... One thing I done differently is actually shutting it off. Always left it on before but I am burning in new DACS and feel that the Canamp doesn´t need anymore burn in. I will try keeping it on today and see what happens tomorrow.

I am burning in my DAC though and it´s still attached to the Canamp so maybe something with that?

I now removed the cotton wool and so far it looks good no more discharges but a bit early to say hey .

Yup seemed like the cotton wool was the issue in some way. I used about the amount shown in pictures... One thing I noticed though is that I am not hundred percent sure the drivers are totally free from the felt disks. Some part of them may touch a little so may try see if I can find a position where it´s totally free.

Well doesn't wool cause static electricity build up if its rubbed? Same thing as dragging your socks on a carpet?

Still weird that you are the only one as of yet that has had this problem. I do think there is some contact between the metal and your wool, that shouldn't be there

Hmmm, Van der Graaf on der Head go Phhhhhttt... Snap Crackle Pop!!

Listened to bass-heavy music for the first ten minutes of my PRO 900 that just arrived, then did mod. It really did rein in the bass lol. I did some things wrong though, the felt discs are half the size Kees used so I had to doublestack them, and also they are a bit smaller, the same exact size as the black stickers Ultrasone put on the 2nd and 4th hole. Then the cotton make-up thing my mom only has rectangles so I outlined it with a roll of scotch-tape and cut the circle that way . The cotton is frayed a bit though, and is probably touching the wires. I'll let you know if I get any static.

I am running out of cotton wool so I put another thinnest possible layer on top of the thinnest possible I already had. I don´t know if it´s my DAC or power cable that is giving me more bass than ever but the PRO 900 is certainly quite warm still may have to find some more. I don´t wear any make up so what can I google to find these pads guess they are quite common.

As for static yes I did get it back but not as much with another set of cotton wool... I can live with one sting per day max lol Are you guys really sure you never get it? Maybe you have really tiny ears that you can never get to touch the metal

What cotton wool are you using if not make-up pads? I reopened my HFI-2200's to take out some cotton I stuffed in there for laughs and little pieces of cotton were all over the case of the driver, so I bet if you have some funky cotton wool it could be causing a lot of static. And lol at your diode board going off I presume static is pretty harmless to headphone drivers though right?
