mmmm.... i don't hear any hiss from my ksc75s and stock apple earbuds?

post #47 of 128

that's because their sensitivity and impedance is different.

i see..... its not my headphones fault but the source that is fault correct? i wanna make sure i didn't get a defective pair or something lol

yeah it's just the synergy between your source and the iem. You could try another source just to make sure. But that background "white noise" like hum is just typical hiss, not a defect.

I'm not sure what the technical reasoning behind it is but it's nothing to be worried about. A lot of very sensitive earphones with some bad sources have hiss. My old Sony hissed quite a bit. Usually you can't hear it when music is on or you can add an amp in between.

He he , did'nt realize this was your thread @rarwster  I just clicked on the last post before .

So your not keen on the cable  ,its really not that bad and does not hold that much memory .

When you are used to cables such as the one on your W3 it definitely is pretty bad. Mine has a good amount of memory but not as much as my R02 but that's a much cheaper product. The length is also an issue since it is not long enough. It's just not a very good cable imo.

yup.... still get the hiss on a desktop.....

post #55 of 128

not surprising as most desktops tend to hiss. You can always use a impedance adapter or a different source.

netbooks and desktops assuming stock as in no upgraded sound cards are a hit or miss. My netbook output is garbage and sucks. I would only use it to watch videos online and that is the only time I use my headphone out on my netbook. The best way to reduce it is to get an amp although that is costly. You can get an impedance adapter since I do find that they tend to do well on dynamic drivers but you will need to be able to provide them enough power which usually means an amp of some kind. I did try an impedance adapter with the J3 as source and while it wasn't bad there's not much headroom really.

is this normal for this headphone? or what can i try these on to make sure that its not the headphones but the source?

it's already been mentioned that hiss is normal. Your sources just produce hiss. It's not that big a deal.

post #59 of 128

right but turning up my ipod halfway up you can still hear some of the hiss. I just want to make sure that its not the headphones. What sources have you guys used that don't produce hiss? without amp that is

Inks , has already given you the key to your issue.

 

When I had the chance to test the 'phones I too noticed that

the level of hiss was above average to me, but that's in regard

to my pretty sensitive hearing.
