Sony touts the HT-AX7 as a revolution in the portable wireless home audio space. It is technically a modular kit, with 2 'satellite' sub-speakers that can detach from the main unit to create a "bubble" of "three-dimensional surround sound" around the user or users with 360 Spatial Sound Mapping technology. The HT-AX7 set is rated to last for up to 30 hours per charge, and is available to order from now.https://www.notebookcheck.net/Sony-HT-AX7-launches-as-a-new-form-of-speaker-to-bring-Cinematic-Sound-Everywhere.732702.0.html
It will be overpriced and perform subpar.
