Delivery very fast in very good packaging. Unpacking, set up, connect with HDMI cable and you're able. Of course it's no 5.1-conditioning! The Dyon's our Samsung Smart TV a clearer, richer sound. The sound is running 100% in sync with the Smart TV. The 3 selectable areas (TV, music, film) can differ in my opinion only a trained ear - all sounds quite similar, but good. With the setting of the tone you have a little "play" and TV, to get us a T-Home Receiver and Dyon in a personally desired sound. Once set, it remains active until you makes a change. The Dyon automatically turns on when you turn on the TV and just off again. The small credit card-sized remote control you need far better than ever. The Dyon sonicated at us a 30 sqm living room and are quite a surround experience of 2.1-type. Coupling via Bluetooth via smartphone works flawlessly! From the price-performance ratio her top and definitely recommended for use as described above!
