Can you hear a high frequency noise in the left side? I have this noise in the left side but not in the right side. Just want to know if this is a common problem or just my pair. Thanks a lot!

 


Might be the recording, can you play it in mono or reverse the channels going to the amp/phones?

I hope it is not something serious like a damaged driver, and it is just that one instance being too bassy.

Mine just arrived new in the mail today, and the left cup sounds like a plastic shaker egg, meaning I can literally shake it and hear broken bits of stuff rattling around inside.

Does the K712 have a sort of pivot joint that you can move the top of the cups in and out so that you have even pressure from the top of the cup to the bottom like the K812?

yep, also the wire headband that gives the whole thing structure is very flexible, they're the most comfortable headphones I've ever worn.

I hear it in both left and right ears, tested by listening one at a time. Nice catch for you, but sinewavesounds.co.uk needs to step their game up because there are a ton of noises besides a 60hz hum in that clip!

I just joined to post my issue as well. My also has that rattling high-freq sound as well, but in the right ear cup. It's caused me soo many annoyances, becuase I listen to music like Nujabe's and I can sometimes hear it. Or when I play FPS games and there's low bass sounding explosions it also becomes noticeable. I'm going to send these back to Amazon and get another pair, in the "hopes" that it won't have this issue.

 

Really can't deal with how annoying it sounds when exposed to those bass sounds = /

Also that 60hz bass test, REALLY makes it obvious lol.

Any advice on how to contact Hector Hernandez from the AKG service department without sending numerous emails and messages? I attempted to contact him via email & phone on Friday with no luck so far.
