[S4 II changes?]

Looking on the specs page from here, the only difference if that the II has different A different shaped cord. It's flat so maybe it's harder to get tangled up or something like that.The rest seem exactly the same to me.

[Crackling noise when insering ear phones]

And when you say the noise will go away after a while, do you mean the speaker diaphragm will break, and it will still work. Or is the noise something else?

Thank you.

[Crackling noise when insering ear phones]

Hi.

Thanks for the replies, I bought them from amazon.com. The seller itself was amazon llc, not some other shop selling via amazon.com. the Image S2s had a small pinhole at the back of eaach earpiece to let air out even if the ear tips formed an airtight seal in the ear. I can't seem to find any such hole in the S4s. Anyway, it's not a big problem.

[Crackling noise when insering ear phones]

I just got a pair of these http://www.klipsch.com/image-s4-black-in-ear-headphones

Every time I put them in my ears there's a crackling noise from the things. It feels like it is forming an air-tight seal with the ear and when I push it further in, it is causing something to get compressed inside the earphone.Is this a concern? Sometimes just adjusting the ear phones causes this noise. I am worried it might be the speaker diaphragm itself getting pushed.

I was using a pair of these http://www.klipsch.com/image-s2-in-ear-headphones for about 2 years and never had this problem, but those had a tiny pinhole on the earphones to let the air out.

Thanks for any help.
