I originally bought a cheapo 50ft headphone ext but it sucked. The sound was horrible when its transmitted to the sound system. So i bought 2 pcs of cable Mediabridge - 3.5mm Male To (2) RCA Stereo Audio Cable - (25 Feet) and used this to connect both cables to make it 50ft. Right when i got it, tried it on our Denon speaker system, and works magic. The ipod sounded perfectly. This didn't affect the sound quality. Loving it, thus the 5-star :-)
