To clarify, these hearing aids function as both a streamer (for music, phone calls) and a remote control for iPhones only.
With a Samsung or similar smartphone, the remote control function only is available!
With the SIEMENS PURE BINAX, again only the remote functions are available, UNLESS you also use a EasyTek neck-worn device too.
With PHONAK VENTURE, UNITRON NORTH, WIDEX UNIQUE and OTICON ALTA2, a streamer must also be used to have any app. functionality.
Our view is IF you have an iPhone, consider the Resound LiNX2. If not, go for PHONAK VENTURE with a COMPILOT AIR II streamer.
