Bluetooth Speaker

I like to find a simple thing to make something easy.
The easy way to listen music for mobile device, like phone and table would be more important in my life. Except the a dock within speaker, I prefer a really speaker, especially a wireless speaker.

Bluetooth is the go-to option for anyone looking for a (usually) cheap and easy wireless speaker. Bluetooth speakers are ideal for households that aren't strictly Apple-centric, since they work with all nearly all smartphones (Android, Windows Phone, BlackBerry) and many Android tablets, as well as all iPhones, iPads, and all iPod Touch models (except for the first-gen Touch).

The only real downside is that audio fidelity is often a step down from the non-Bluetooth options like AirPlay speakers -- but a lot of people can't hear the difference, and the quality is generally much better than Bluetooth audio devices sounded just a couple of years ago. Note that many (but not all) Bluetooth speakers are designed with rechargeable batteries, so they can be moved from room to room with ease. Travel models are even smaller, and often include speakerphone functionality as well.
