The Sound Blaster Roar has a great sound for its size and is so versatile: NFC / Blutooth Speaker with recording function (requires Micro SD), speakerphone for paired phone, alarm function, can serve as an external sound card SM PC or MAC. (Requires Creative driver from the website). Can music / recordings represented by buttons on the device. It can be 2 SoundBlaster roar coupled via a special cable to widen the base. Implemented very well thought out and super - gerne wieder :) single point lacks somehow the mobile app to configure - the PC you go without problems :)
