For those interested i find it easily accomodates three standard sized rubber made bins across (see photo) plus room for an additional narrow item (i am estimating up to 12 inches for such item)Also note that with incandescent rola light kit there was space for rubber made bins to be placed without contacting lights (the back of lights protrude somewhat into carrier cargo area). En bref, passez votre chemin et achetez-vous un meilleur produit (quitte à économiser un peu plus). The sound quality is great too, nice crisp highs and thundering bass that you can feel on your ears. Have not worn them outside yet but they are perfect for casual and semi dress. Battery life is wonderful and I love the on and off switch so I know its off. Its a great fit if you are low on space or have a small apartment like mine. Disappointed in this product is an understatement, especially because I bought another pair for my sister (tan color) and there is no stitching under the toe strap and they are suede like soft. A must have if you go off pavement. Upon development of the rash I stopped using Vanicream Baby Wash, but the rash would not go away. So far, velcro holding well; have only worn a dozen times so far.
