I think you have an issue with your electronics. Pop using different cans?

Static electricity release on h/p/a body ?...

I think the problem is the Topping DX1 I am using, I found another report online about the usb cable being the problem. I also tried my btr7 wirelessly with no problems.

Do any of you noticed any random pops on the driver during playback sometimes?

I did, more than a year ago, during the first weeks of use. Sometimes, one or two minutes after putting the headphone on my head, one little pop was heard in one or both drivers (not simultaneously), very much like static. It disappeared gradually after the first weeks. Now I think it was something caused by thermal expansion, maybe the internal shell of the cup (plastic) expanding inside the external (aluminum), after receiving the first heat from the head, or something like that (maybe it was an aluminum part expanding more than plastic since aluminum has a big thermal expansion coefficient.) Even if it was coming from the membrane itself I believe it was something thermal. I think too much, overheating my brain, lol !

Ed. I should have tried to put the headphones on my head with no music or connection to check if it was temperature related but It disappeared before becoming a problem. Maybe you can try that.

Apart from the above, I experienced pops like static (at L-chanel with all headphones) only when my smartphone is driving a dac. A problem of software / clocking / hardware I think.

Here are three albums I have been listening to during the last few days. Just beautiful music, high-quality recordings, excellent musicians, with superb headphones (NDH 30, of course):

Enjoy!

I also have the DX1 and no issues at all with pops using my current cans (in my signature).

Burn in effect...literally...LOL

I noticed this on the btr7 too, but upon further inspection, its more like a bit of eventual creaking from the metal/plastic part.

Did any of you compare the black and silver version? Are there any sonic changes between them?

It’s been established that they are the same except for the colour. Any differences (and they won’t be identical) are just normal sample variation.
However, it’s worth noting that if a particular example of a black 30 happens to have slightly less treble energy than a particular example of a silver 30 the natural thing to do would be to think that the black version is different because of the colour, reinforced by the psychological effect of sound and colour association. That’s a real phenomenon that has been discussed on this forum in the past.

Jesus, I wanted a black one, but now I HAVE to get a silver one, because I’ve read your post an KNOW the black lacks in treble!

I laughed during reading your comment, because first thing my brain said while I saw the black version was "it's going to have more bass". Stopped for a sec and thought: "what just happened?".

Stumbled upon Tomas Fujiwara and enjoying it with the 30 very much.

Beyerdynamic A20 (output impedance: 100 ohms) is a great h/p/a for NDH-30 (nominal impedance: 120 ohms).

With a system damping factor of 1.2x, here is a wonderful mix of driver control / sound blossoming. No 'stranglehold' here leading to obedient, timid sound!

This CD player is no slouch either! Love those TEAC players!
