There seems to be one by a company called Geekria if you look on Amazon. Look for 3.5mm stereo male plug to 4.4mm balanced.Thank you, But I meant the other way. My headphone cables end in a 4.4 mm PentaConn and I would like to convert that one to 3.5 mm/6.3 mm when using the headphone with a receiver, and the 4.4 mm when using it an ifi Hip Dac2.
