The Bluetooth Speaker Hat from Brando is a tech clothing item that serves two purposes. It is an acrylic hat that will keep your head warm when itβs cold outside and itβs a Bluetooth speaker with phone capability. The hat charges via micro USB (Never thought Iβd write that sentence) and features a microphone and a three button touch interface that controls volume and music playback. Priced at $28, the Bluetooth Speaker Hat is available from Brando.
