I've always had to chain myself to a PC as far as multimedia was concerned because that was the only place I could have any sort of real control over the sound. Bass, treble, depth, equalizers, sound mixers, I've tried them all. I really cannot overstate how liberating a technology like BT LE is. Right in my remote control I have those settings for equalizers - I can even mute the live microphone & focus on just the movie I'm watching, rather than the low brow people gunning their engines outside.
This also presents a bit of a quandry. I enjoy watching the Simpsons but I haven't always had captioning in order to understand whatever scheme Homer has planned this week. Now that I have them, should I start over from the beginning with that series? It's been on the air for over 30 years! That's going to take forever!
