Bluetooth headset cable required. The one that came with my headset didn't support a microphone, which I thought was an extremely bad way to save money. These cables are cheap, but there's a reason for that. There is a delay of about 1.5 seconds when using it. In a digital world where everything is processed in microseconds, 1.5 seconds is considered huge. I haven't noticed any degradation in sound quality with these cables, but I use them primarily for speech, not music. If you're just using it for listening you probably won't notice a difference (you won't notice any lag), but if you were, would I use the OEM cable that came with my headset. Glad they were relatively cheap.
