The AVR fits into your Sonos system and plays to headphones over bidirectional Bluetooth® wireless technology. With 75 years of hi-fi knowhow elevating Onkyo’s THX® Certified Select and IMAX® Enhanced certified RZ Series custom amp design, music, film scores, and game soundtracks thrill with emotion, sound perfected by Dirac Live® Room Correction. This AVR has features others don’t, such as front-to-height stereo switching for background listening, DSP vocal/dialog enhancement, My Volume presets, and an OSD function that compares source data to output settings so playback can be optimized before entertainment kicks off.
