They are slip-ons. If you are just looking to hear yourself and not blast out your ears with loud monitors, this will do just fine. These seem to run large, and they do not support your feet. Its also pretty reasonably priced for an official Bose product accessory but thats probably because its such a must-have it really should have been included in the package with the speaker in the first place. Good gaming headset, good mic, sub par speakers. Quality is just as I would expect for fit flops and they were Cost effective. However, there is a tradeoff for this lightness and that is noise cancelling. If you are reading these words, get yourself a pair - I do not believe you will be disappointed :)IN CLOSING:This is a review being written while isolating and trying to stay safe and healthy. Not the quality I was expecting. They dont touch any wall to the left or the right.
