Run a linear sine sweep.
While doing so, you should-
Try different insertion depths.
Try different tips.
Try switching the earpieces to opposite ears, if possible.
Try the same on different IEMS.
If you're using an iPhone, I recommend AudioSigGen (free).
Software that can generate a sine sweep is also available on PC and on Android.
You can also find one or generate one on Audiocheck.net
Be aware that most IEMs have slight channel matching issues which will sound pretty drastic via a linear sine sweep, but will be practically unnoticeable when listening to music, but you say it's audible in music so....
Joker also mentioned recently in response to one of my posts that you can also try converting a couple of tracks to Mono and listening that way for channel imbalances.
If its a serious channel imbalance, I sincerely hope Noble will, at the least, look into it. AND if there is an issue, I would expect them to refund you return shipping if it's a manufacturer defect and still under warranty, you know cuz they pride themselves on doing the right thing for their customers, *ahem*.
