APP DESCRIPTION Its main scope is to route MULTIMEDIA audio flows on: 1. stereo car systems, which can be interfaced via bluetooth exclusively in telephone mode, or used as such 2. bluetooth earphones supporting only phone calls (not equipped with multimedia channels). More specifically, this app lets you stream multimedia content (audio, music, etc.) to bluetooth devices that DO NOT support multimedia channels, but only "phone calls". Usually such devices, such as stereo car systems or mono headphones, do not allow you to listen to audio streams and music with Bluetooth headphones. Instead, with this app, all this will become possible, specifically you can listen to voice messages from my FREE NOTIFICATION READER! Common issues due to devices and Android limits: - the sound quality is not particularly good - not all smartphone models are compatible - there are some problems with Samsung Galaxy S2 and S3 (and not only) - sometimes the process may be interrupted by Android. ENJOY IT!
