Have had this for over a month. I wanted to use the included optical cable to avoid connecting to Bluetooth each time. It didn't get loud enough and started buzzing at higher volumes. It doesn't turn off on it's own without input even though it can detect no input, which is annoying. It does connect quickly via Bluetooth. It sounds good and doesn't appear to have any delay in sound. Really a good product for the price. I do recommend it for the price range
I got this bc my gma has to have the volume all the way up. We hear it over theliving room t.v. we hsve to shut doors. Ect. I put this right next to her. She is a lot happier she can hear, so thats a huge plus. As well as we can now hear if some try to breakin using a jack hammer and we can call the proper authoritys. Lol. Sorry bad joke all honesty it a great product and has made everyone very happy!!
