Wentronic Audio / Video cable (2x 3.5mm mono plug to 3.5mm stereo connector) 0.2 m (accessories)
Bought it a few weeks ago and in many different aircraft used (747, 737 & Airbus A340, A320, A321, etc.). It has always fit well and I've noticed never a fault or deterioration of sound quality. I would recommend it without hesitation!
