Good ol JBL failed to explain that the flip 4 and newer speakers DO NOT connect to the Xtreme or earlier models. I hope that everyone has better luck than me. I have always been a BOSE fan (except for their prices) and this thing, I could not ask for more. My husband is a holistic physician and is very picky about any products that go on his skin. The big downside is the image quality in the VR headset is really poor compared to the non VR game, the resolution looks to be quite low & theres a grainy effect. I was honestly shocked when it came in. Once satisfied with location of the roof rack assembly and the bar, continue to completely tighten the roof rack assembly. It worked. The casing is sturdy and metallic, giving that ?built to last? feeling. ? SPEED ?These things connect so fast you dont even notice.
