For any concerns over the jack lengths as I was, this appears to have been corrected and in terms of fitment is exactly the same as the cable included with the headset. Functions but I will say the issue of the cable picking up every movement as it shifts across my desk is quite annoying. The cable feels good in hand but they definitely could have either insulated it better or used a softer material so that less sound would transfer through the cable.
