OB–4 is Teenage Engineering's ultra thin bluetooth speaker with a sound larger than its appearance and really long battery life. Discover deep bass and crystal clear, open and natural audio that fills the entire room. The handle houses an extra antenna and makes it a breeze to carry – it can also be used as a stand for more relaxed listening.
OB–4 continuously memorizes everything you listen to on an endless looping tape. Rewind, time-stretch and loop at the flick of your fingertips.
