Bad recording

Oh really? Maybe that's why it only happens in some songs.
Hope it is just bad record as you said.
Thanks!

I have the T-Peos Altone 200's and love them. Just bought a pair of DUNU 2000J's. Hoping for a mid boost to the vocals and even more of that awesome dynamic driver bass texture.

I think sometims a torn diaphragm or loose housing can cause that sound, but it could also be in the recording (esp since you mention it increases with EQ). You could try using a test recording,  tone generator or a bass synth to see if the problem reproduces plenty of those via web search. could be your hardware as well if another headphone with good low-end response reproduces the same problem- are you using the bass rings too, with the eq boost you mention could be causing some kinda driver flex or something?

Driver flex can damage diaphragm?

Over time...sure.  That's the main reason I returned my DN2000Js...just didn't want to risk it because of how much flex I was getting putting them in and out all of the time.

are there driver flex with dn2000j

Look up ONE post.

The only time I get flex is if using the bass rings. No flex at all if you don't use them (in my case anyway)

Hmm, was thinking about getting it in future but the driver flex problem scare me away

lol. I don't give a ****.

If I pull my ear and gently slide this in usually there is no problem...
However put those bass ring, I get driver flex 60-70% of time even if I insert with care.
Now I am thinking of not using bass ring. 

 

[Whitigir]

To think something that is 300+ to have driver flex problem ? Lol...

 

[tomscy2000]

The K3003 will also have driver flex if the silicone ring is put on it. Physics, people. LOL

 

[mochill]

My rockets have driver flex and I sent I to be repaired because of it
