Very cost effective solution,

No loss in output/sound quality at all. The fit is a little tight because Microsoft deliberately designed the Xbox 360 to be that way. Plug the HDMI lead in 1st and the adapter 2nd, it's easier that way. The HDMI lead is actually of far better quality than some leads of 3x the price. So overall I'm pretty impressed with the kit, well worth it for anyone wanting to have HD visuals AND top sound output from any HiFi or Sound System with an AUX input.
