Unbearable noise analog or digital. Just deficient

The handset came, although new and closed without left ear cushion to. As has happened to me also a mystery. I have tried the device then anyway and was pleasantly surprised. First. It dissolves in the heights less than the Sennheiser RS220 and the bass is a bit vague, but he does not sound like a headset only costs 1/4 of the price. Do the video shows and chores I had to keep him happy. Only in the quiet passages are constantly audible whistling noise drives one after 30 minutes to madness. It does not matter whether the sound through the digital or analog input comes. The coverage, however, was far better than the RS220.

Too bad, without the interference would be the Philips for 120 euros an absolute recommendation.

Supplement: The Amazon quickly provided replacement device is even worse. For pipes still was added a Brumgeräusch!
WTF Philips Fidelio Euro Series is great, but this? Tests your own stuff before you throw them on the market? Where is
the quality control? Have estimated the case of a handset, for her 200 times, absolutely out of the question!
