She is 12 it had no instructions but she seemed to pick it up good. Given that not even top-end graphics cards can consistently achieve that at this resolution, I look at this more as a future-proof feature. It is a great case, looks classy, sturdy but the whole design depends on the top lid adherence to the AirPod’s top Lid, there are times the top lid becomes loose, so the whole structure gets affected, the lid does not close. There are some settings you have to change in your Xbox One audio output options to get the best sound. FWIW, What worked for me: (1) to my windows settings and (2) select the headphones as my audio output, then (3) select the special Windows headphone profile from the two options, and them (4) pair them with the computer Bluetooth as I would any other BT device. The sound is impressive for its size. International phones are not produced to work particularly well in the US, and do not often have the LTE bands necessary to have good service. I have not used this rug myself, but it appears to be nice quality, is soft underfoot & comes with a guarantee. I really enjoy these headphones.
