The HP-BT1 Bluetooth Earbuds are designed with three simple yet important elements in mind: comfort, fit and convenience. Their unique shape has proven to be extremely comfortable, appealing to music lovers, mobile office and leisure users. They are designed to fit most ears, with a lengthy staff to keep them in place and to prevent them from falling out. A convenient custom charging case with included USB cable makes charging them as simple as putting them back into the case when you're done. With a compact footprint, these earbuds are handy for those who are on the move and want to carry them in a pocket.
