Humming/Buzzing Charger Plug

[George H Martin]

I just noticed that my charging plug makes a humming/buzzing sound when plugged in. Is anybody else's charger plug humming? I had the same with the charger that came with my Nexus 5. Is this a normal thing (normal for LG Chargers)?? Or is it batch/wide spread issue? Should i take it back to the shop?

No buzzing on my model. You may wanna have that replaced
