We love this shirt so much , the fabric is soft cotton and so comfortable, the first one I ordered for my son was too small , he is 7 and I ordered size small I returned it and replaced it with the one he is wearing in this picture. Then of course I won’t be able to return. It turned out to be on the side of the TV, not the back. The wing-shaped extension on the earbud cover is pressed into the folds of one’s ear, in addition to the rubber part which fits into the ear hole. Now place the unit on a flat surface and tighten the screws in the larger ends. It immediately feels lighter on my head than the standard Quest 2 strap, much more comfortable. I’ve been using this speaker for a couple of days now. I am so happy that the fit is wide. They feel reliable. Try it, but don’t tell anyone how great it is.
