Problem with PX100's

post #1 of 19
Thread Starter 
So recently i bought PX100 along witn nano as a present for my girl. But when i tried the Px100 (a lot of good things about them here on head-fi) i'v noticed clicking sounds on bass-heavy sequences on high volume levels. Don't really know, but i think it's because the driver vibrating on loud bass touching the plastic in front of it. So i take the earpads off and found that there's very little to no space between the driver and plastic cover that in addition turned inwards.
So please tell me what to do.. If you have the PX100, try them on higher volume levels on bass-heavy music. (or you can try 20-60hz sine sweep).
In most cases, nano itself is unable to cause this distortions because of inability to reach higher-volume levels, but i really sad anyway...

An advice...

Seriously, buddy, lower your volume, you know, you've only got ONE pair of ears...

Oh, you're right! But it's not THAT loud, there's no such problems on my other portable cans, let alone full-sized...
Maybe i haven't made it clear, but i'm not talking about high-volume distortions here, i'm talking about specific abnormal clicking on high, yet comfortable volume level

May be comfortable to you as you may have damaged your hearing. Personally I can't turn any of my sources past halfway on the volume knob without it being too loud on my PX100s. I think you've got it turned way too high, causing the noise. I've never had problem build wise and I've never heard of this problem before

Maybe i've just got defective pair? Not likely, because both drivers clicking, not just one.
Volume level...um...105, maybe 110% of nano's max volume level-is it too loud? it's the loudness level when the clicking arrives. Or 90% of nano's max output when bass boost or any other EQ preset with enhanced bass is on. Not hell of a loud i think...

You have the Nano's volume at max?! On the headphone out?! Wow, I tried a mate's Nano 2G and 60% is the max I'll have it on cans, depending on how loud my surroundings are. With my UM2s of course, I could have it at around 35%, really

I never notice any problems with my PX-100. Then again, I never listen at such high volume (yes, I think you are doing it too loud) and I don't EQ my sound (clipping is your likely culprit).

I envy you if you can listen low-volume outdoors...

Well..you should have gone with a closed set of phones then.

Yes...but there's not much options of good sounding closed phones that do not require an amp

The problem is exactly an insanely high listening volume.

I can replicate your problem (crackling sound on bass hits) but in order to have the crackling I need to turn the volume so high that it really hurts my ears.
In fact the crackling shows up at such a high volume that I cannot withstand having the phones on my ears at that loudness, i had to listen to the crackling sound from a distance of a couple inches between ear and driver.

You are given only one pair of ears... Once you're deaf that's forever. Take care of your hearing buddy.

oh.. i DO KNOW that every headphone WILL crack on extremely high volume levels on bass. I do not talk about that! I'v got a specific problem that i've never experienced on any other cans. Prolly i will never able to correctly describe the problem due to my language issues, so forget it.

I listen with high volumes with my PX100s all the time and I've never heard a clicking sound. I would exchange them for a different set and see if that solves the problem.

Do you EQ your bass like he did? I'm positive the EQ-ing, coupled with the high volume, is what's causing the problem.

My girlfriend has a Nano and it was too loud for me past 50% using my iGrados which have the same impedence (32 ohms) as PX100s. Turn it down!
