I don't need it but it's fun to watch people's faces, they generally aren't ready for it and are smiling/laughing every time. Never had anyone give me a "meh" afterwards. The best responses were from my kids' friends - seems like everybody owns a little bluetooth speaker for their whole house and that's it!
Validation
To go along with my post about how competitive you are regarding your set, is this question: Do you need someone to validate the quality of your set or can you be happy with it all by yourself? In my case, no one has heard my set in a long time and I’ve made many improvements. So far, I’m very pleased with what I’ve done, but I do wonder what others might think.
How about you?
