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.

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

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!
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!
