Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Poor Right Out of the BOX!
After reading the variety of reviews on Amazon I still went ahead and bought a pair.  What a mistake!  First I waited 24 hours for the batteries to charge, a little long bey hey, I waited patiently.  Next, the base unit wouldn't turn on.  Instruction said the base unit automatically turns on when the headphones are turned on.  Nope.  I had to unplug the base unit and plug back in to turn it on.  Next, they a constant low level hissing...on every channel.  And don't change headphone channels with them on your ears or you get a very LOUD popping noise.  And the grand finale was they automatically shut off every 3-5 minutes.  Packing them up tomorrow and shipin em back...
