are my new AKG K27i broken?

[unknown00]

i just bought a new pair of AKG K27i from headphone.com and i think it is broken. okay well, i'm pretty sure everyone knows about the volume controlling bar on the wire right? AKG calls it the "integrated precision volume control". when the volume bar is at max, headphones work perfectly fine. if at all though, i move it down a little bit, the music sounds terrible. sounds like no treble no bass just plain creaky scratchy messed up music. is this normal or what? should i send it back?

thanks in advance for replies!

What are you driving these with? Could be a case of severe underdamping - the volume control is nothing but a stereo pot in series with the drivers. Do they work fine if you leave the volume at max and crank up the volume?

main thing i'm using it with is my laptop. tested it with my w850 walkman and an ipod same problem for all 3. and yes it works fine if i leave it at max and crank up the volume. so...should i send it back?

Hey there, I had the same problem with mine after some time. Easy fix, take a small drop of rubbing alcohol and drop it in the volume slider, then slide it.. Blow on it to make it evaporate, should eliminate the staticy sound and improve the contact on the volume slider.

Not surprising. Usually DIY people encounter this problem quite often with cheaper adjustable attenuators. Sometimes the attenuator gets contaminated with dust because components inside grind against each other.
