Abstract: A mono-body set of headphones having a fixed length of headband between ear pads is provided. Although the distance between the ear pads is fixed, the fit of the headphones can be adjusted to the head of the user by coupling or decoupling a removable/insertable headphone pad. More particularly, a pad is provided that can be mated with, or removed from, the headband of the headphones, thus raising or lowering the lower surface of the headband relative to the crown of the user's head, in order to change the position of the ear pads relative to the user's ears. The mono-body headphones are, preferably, flexible and durable, permitting the headphones to be straightened, twisted or bent without breaking.

Snap-locking mechanisms are each configured to lock the center part to a respective one of the upper and lower parts, so as to cover the rear and sides of the mobile telephone in an assembled condition of the case. A plurality of interchangeable center parts may be provided with different patterns, colors, textures or indicia.

Abstract: A tri-fold case for a tablet computer includes front and rear covers, a spine and hinges for rotating the covers and converting the case between storage and standing positions. The front cover has corner folding lines dividing the front cover into a center portion and corners. The rear cover has cutout flaps and flap folding lines for bending the flaps away from the rear cover. The front and rear covers have outer surfaces facing away from each other and inner surfaces facing toward each other for receiving the tablet computer in the storage position. The outer surfaces of the covers face each other, the corners are bent along the corner folding lines and the flaps are bent along the flap folding lines and attached to the outer surface of the front cover, for supporting the tablet computer at the outer surface of the rear cover in the standing position.

Abstract: A case for a portable digital device, such as a mobile telephone or a portable digital media player, includes a set of interchangeable rear panels having different appearances or functions at least at one outer surface thereof. Two mutually interlocking shells engage one of the rear panels. The shells and the panels cooperate for receiving and locking the device within the shells and in front of the one rear panel.

Abstract: A casing for a portable electronic device, such as an MP3 player, a cell phone, a smart phone, or a PDA, is formed with two or more sleeves that may be placed onto the electronic device and together form a closed encasement for the electronic device. The encasement is formed to enable operative access to the electronic device while the sleeves are connected to form the closed encasement. A back panel of the encasement is removable so that it may be exchanged for an alternative panel. That is, a first back panel may simply be a planar panel that only forms an integral backwall part of the closed encasement and a second back panel may be provided with a belt clip or belt loop, or the like. The different removable back panels may thus be exchanged to provide the device for mutually different functions of the casing.
