Hi.

I've owned a pair of Sennheiser RS-85s for about 6 months now. I've
lived in two different places during that time, and in both places I
have had terrible, terrible range. Absolutely any wall (drywall, not
concrete) causes me to get so much interference that it's not worth
listening. If I sit on my bed, which is about 5m from the transmitter,
and lean my head the wrong way it cracks up. I have 3 phones in my
apartment, but they all run on 900mhz. I'm sure someone around has a
2.4 phone, but I didn't think it could cause that much trouble (I've
never had that problem with any cordless phone.

Is this normal for these headphones?
