On 30 April 2001 Altec Lansing Technologies launched their first line of headphones named as the AHP series. This series of headphones had various different designs and price ranges. In February 2004, Altec Lansing Technologies reissued a number of loudspeakers starting with the A7 Voice of the Theatre, manufactured in the US with some changes to the enclosure. Similarly, Altec Lansing Technologies reissued the 510, 508 and 305 loudspeakers. Very few were actually made. On July 11, 2005, Altec Lansing Technologies announced that it was to be acquired by Plantronics for approximately $166 million. On September 10, 2008, Altec Lansing Technologies went through a corporate makeover changing its name to Altec Lansing LLC and its logo from a "whirlpool" to an abstraction of a multi-cellular horn.
