Review on Hi-Fi 3.5mm Headphone Extension Cable 2-Pack - Oldboytech [3.3ft/1M, Nylon-Braided] Male to Female AUX Extension Cord for iPad, iPod, Speaker, Smartphone, Tablets & More by Adam Cooper

I've had so many extension cords that they let me down. Oldboytech is great and solves my problems. I have an old MacPro and am concerned that damaging the onboard 3.5mm jacks will cause the motherboard to fail. So I've now added Oldboytech to all front and rear audio panels. In fact, the kit includes two wires in a pretty little brown envelope. The male and female have a narrow diameter bracket which also means you can easily use them on iPad, iPhone (I used them on 6s).
