Well, Mr. Gilmore was so kind to come up with a tentative explanation. He said storing the headphones in a plastic bag could be the cause as they probably sit in a very humid air - the moisture could be due to sweaty earpads. It makes some sense to me as the malfunction tends to appear at the beginning of the warm period of the year.
If this is correct, the only question is if the driver is permanently damaged or it could "dry" somehow and spare me of the hassle of another driver replacement. Mr. Gilmore suggested I leave the amp on with the phones connected for 2-3 days and see if the buzz goes away definitively. I'm only worried the amp could overheat - it sits in a piece of furniture with many ventilation holes in the back and some 30 cm. of room all around it, but the doors should stay closed during the day and my room is very warm during the summer (no air conditioning). I'll find a solution.
