I contacted Thule and they informed me how to fit them the correct way! Do not go bye size chart! The sound is not very good Yeah, the DT 990 are no slouches, but they dont transmit the emotion that the DT 880 do. Im 5ft 5" and about 140lbs now and while its not falling off my waist, it is very loose and also longer than I anticipated. I could even use the headset for M/S Teams. Look great, feels great Some reviews say to order down a size, some say true to size and others swear by ordering up. My Samsung S10 with thick Ballistic case fits snuggly, I feel very secure with it. If using as shelves inside the cubbies, just use something like twine or gardening wire, and hang it from the shelf edges above.
