Sensitive in what way? Certain frequencies?
I took it to mean off balance. I suppose our brains adjust for stuff we can see, but not stuff we can't.
Perhaps the balance control on headphone amps has gone the way of tone controls on other amps. But with a PC being the usual source these days, such things are easy to fix there. @TheIceman93 specifies an analogue fix.
If his amp does not have a balance control... a pre-amp that does. Or one of those little boxes. Schiit do a low-cost one; Goldpoint make pricier stuff. There was a thread...
Wideband or certain frequencies? If the former you could DIY something like this https://diyaudioheaven.wordpress.com/headphones/headphone-attenuation-adapter/
If you know target -dB you can probably get a good guess at the load R you'd need.
I guess I would need to see an audiologist to know for sure but everything seems slightly off center, pushed to the left.
I use a CD player as a source so I require an analogue balance control
Ah, understood. I was thinking you could use some sort of digital tool to estimate the loudness imbalance, then attenuate one channel to the level you'd need. I guess that's complicated vs. just a balance control off the shelf.
Are there audiophile balance controls?
Actually, don't answer that.
