Summary: This is an absolute great addition for an Onkyo receiver without built in blue tooth. Plug and play into the USB port, connect the bluetooth device and control your music from a distance without having to keep walking to the receiver. Super easy to use and Crutchfield had the best price of anybody.
Pros: Plug and Play Easy to use Saves trips to the receiver to change music
Summary: I didn't experience any pairing trouble like other reviewers. Plugged it in, hit 'enter' to make it visible for pairing, and paired directly to my Android phone. Range is disappointing when plugged into the back of my TX-NR818. Intermittently drops connection within 15 feet.
