Q: Just bought a pair of Shure SRH440s, left speaker sounds great but the right one is quieter and more tinny, his there something I can do about it?

A: First make sure the pad on the R side is well seated, that the headphone connector has been inserted all the way into the jack, and that balance levels from your source are in the middle and not skewed towards L or R.

Then do the driver matching test here. Swap the sides around and do it again, if your R earcup is more quiet on the R side the first time around and on the L side the second time, then its a driver issue, and you should return the SRH440.

However if the R earcup is quieter on the R ear the first time around and the second time you do the test the L earcup is quieter (i.e. on the R side both times) then its your ear, you need to see your doctor or audiologist to figure out what is going on.
