As the other reviewer said: It's a star! It absolutely is!
You know what? It's pretty good. It's plastic. But not a cheap plastic, it's slightly heavier than I thought it would be. It is still light but it does have a slight weight to it which is always nice. The cable itself is the perfect size and is very durable. I've tried twisting it and yanking it and it stays in the same place no matter what I do. It's a very solid product indeed.
Well, I know some people out there, past me being one of them, thinks that the volume or sound quality will be reduced due to the number of listeners. Nope. The sound quality is 100% as well as the volume no matter how many of these things you stack together! Yes, I have tried. I had to! It will still be the same as using your headphones directly into your device.
Overall, this is a very simple and very effective product which I will keep for a long, long time.
Don't hesitate. This is perfect for sharing your music with your friends! And such a good idea!
