Review on 🎄 LUMIMAN Smart Christmas Fairy Lights: 32.8ft 100LED USB Color Changing - Wi-Fi, Bluetooth, Music Sync, Works with Alexa & Google Assistant - Twinkle Lights for Christmas Indoor Decor by Hannah Anderson

I honestly have no problems with headlights at all. When I hung them up, I turned them on to make sure every bulb worked and they all worked. I placed my audio device next to a box with a microphone for music. My audio device isn't very loud, so that's to be expected. I love every lighting mode, my favorite is when the light comes from the center. Maybe make it so that users can use their phone by creating their own modes for music (if this is already a feature I must have missed it and I'm sorry). The light is very bright, I imagine if I bought more I would flood the room with color.
