"max graff"

I purchased a set of new Sennheiser HD-555 from a local hifi shop.
They sound really good but at high volumes, low frequencies seem to
crack them. At lower volumes all sounds good.


** So you are driving them with what ????????????

A CD player ?



My older $20 TDK's (though though not as detailed) seem to handle
lower frequencies pretty well or atleast gracefully attenuate them.


** Are they 120 ohms nominal impedance and of "open ear " design ?????

Bet not.
