Your computer has to have Bluetooth as there is no dongle. For the hard of hearing, these receivers may not be loud enough, but considering the price, $15. , 70s and 80s and 90s bands. Only to find out when receiving the item that it doesn?t come with the fitting kit (foot where locks to cars roof rails) I searched online and on the Thule website it said the part for my Mercedes 2016 was discontinued, meaning I had to buy a second hand one on EBay for £45 pounds. Funny enough, this is true even with these, though the toe is exposed. Ive done and am still doing research on shoes. Longest I wore mine was for an 8he shift and I had 0 discomfort. I have one bar that is slightly under 1 inch and while these attach, you can tell it really isnt 100% secure. Just make sure you get the right size LOL THINK AGAIN
