Both headphones paired easily with my smartphone, an LG V35Q Thin. I purchased 12 antiperspirant deodorants expecting to use them over a period of a year or more once my last 2 from previous order were used. The old XB950N1 saves the bass boost settings in the headset and keeps it whenever you plug in the wire, allowing you to use it on a PC without issue. I was concerned about the pattern coming off when I washed them after gardening, so asked the seller if washing liquid & water was ok. Maybe 5 minutes to install? Looks great, works great. You have to have your Bluetooth on to pair them which I don’t understand because they aren’t wireless but the sound is great GOD. Its way better than trying to sleep with the sound of lawn mowers and hedge trimmers. I don’t know how long it lasts on 100% volume with the lights on. To me it feels like this should have just come with a mouse that lists for almost $200 to begin with.
