The Altatac Iblinks product is a fun way to listen to your favorite music. For the price, they are a lot of value, and you can order a few for spares. The LEDs do definitely blink when there is music on, but not exactly the same as you may see some equalizers, or perfectly in beat. Overall excellent value and performance.
very good Product for the money! works great as well and sound good, love the flashing lights its so cool!! :) liked them so much I ordered a second set, shipping was fast too. thank you AltaTac!
