Had direct comparison of these two sound bars. Coupled via Bluetooth and play. But I must say the Panasonic SC-HTB680 was the Sony HTCT370 clearly superior in all services. Very good successful surround sound to the appropriate bass, really enjoyable. Be it cinema or music playback.
At Sony we hear it, the sound coming from the front, no surround effect. Have all sound options tried out but the Panasonic I always had this effect WOW.
