Acoustic Sound Design is the only authorized Harman Kardon dealer that's selling these adapters at a discount.
Brad's Deals Editor Michael,
This Harman Kardon Adapt HD Audio Wireless Adaptor with Bluetooth that's normally $129.99, is being offered for $19.95 with free shipping at Acoustic Sound Design. We could only find these adapters for their full retail price elsewhere. These app-controlled adapters can add wireless streaming to any audio setups and are connected using a 3.5mm jack. With multiple adapters connected to speakers in different rooms, you can have your music follow you as you move around your home or send different songs to each speaker from a single source. There is no sales tax (except NV).
