Just bought headphone and amp. My son noticed very faint humming sound and every time he touched the area around headphone jack, it disappeared. Also when we switched to iem, humming didnt appear. Myself couldnt hear it, probably because of age.

Could it be because of grounding issue? Or issue with the amp or headphone? Headphone itself is a Hifiman. If indeed it is a grounding issue, any ways to resolve? TIA
