Soulpunk RGB Rechargeable Sound Control Light, Voice-Activated Pickup Music Rhythm Lights, Creative Colorful LED Ambient Light, with 15 Modes Music Sync 32-Bit Audio Spectrum for Car（4 Pack-App）

I've got a five figure stereo system. And I really like visual effects like Spectrum analyzers. They are tough to find and most of them are eqs. I am very picky with my stereo and pretty critical of crappy products out there. These things blow me away! They are probably my favorite thing I've ever ordered on Amazon and I'd be embarrassed to find out how much I've ordered over the years! They are well built, very good looking and a lot larger than I was expecting. Although I would have been happy even if they were smaller. I got the one with the app. My phone warned me it was potentially dangerous but I went ahead and downloaded it and I'm sure it's fine. It is incredible! It has probably 20 plus modes that are all very cool and different. So many colors to choose from and I love the fact that it's got a brightness control and a sensitivity. I bought four of them and I love the fact that the app controls all of them at once. They connect perfectly at first and every time. They are responsive and vibrant and have little stands that come with them or they come with little sticky pads. I'm pretty sure the battery only lasts 3 hours or so but I have mine permanently plugged in to a surge protector so they come on with my stereo and are just a perfect addition to the visual appeal. I have no complaints about them at all. I spent about $36 on four of them and I have zero buyer's remorse. If I can think of more uses for them I might even get more. Totally Blown Away how great these are. I'm very surprised about how many different modes and types of visuals it gives you. I doubt you'll be disappointed

I love these things! First of all there's 4 of them which is 4 times the coolness! The whole sound pick up experience is perfect, the light goes perfectly with the music you put on. It has an app that allows you SEVERAL different light scenarios. I think it's an awesome item and would recommend it to to anyone! I love it!

So far no problem with hook up to BT! in app! I do think these should have a auto shut off if no sound is detected, it would be helpful for in car applications!

The media could not be loaded. Love these lights, rechargeable, come with a lil stand. Charging lasts a couple of hours, they recharge quickly. Lotsa fun settings. Move to sound. They also remember their setting after being turned off. Each light is separate, comes in a set of four.

very cool lights voice activated and sound music activated that cool!

Battery life is very short. They stand up well. The lights are pretty nice. No remote for them though so it’s annoying to change them. Cause you also have to change each of them individually. But they look fine. But you almost have to keep them plugged in for them to matter

worked well and were a lot of fun.

These things are fun and work as expected.
