Features:

Strong Connections 
The Etekcity Roverbeats PS78 features a very strong Bluetooth 3.0 connection as well as a supplemental AUX port. Having multiple types of connections available allow the PS78 to sync to a variety of devices. 

Small Speaker, Big Sound 
The Roverbeats PS78 is only 2.5" in diameter and height, but thanks to its high damping paper diaphragm, this speaker can unleash surprising amounts of sound. Don't be afraid to crank up the bass, the diaphragm is designed to handle the load. 

Music On-the-Go 
The Roverbeats PS-78 is so small it easily slips into a backpack or purse without looking or feeling bulky. The rubberized exterior makes the T3 easy to hold and protects it from impacts, it is one of the most portable speakers available. Feel free to leave the charger at home because the lithium battery pack lasts seven hours. 

Chat it Up 
The built in microphone allows for phone calls using the little speaker. If a call comes through during a music-session, the music is instantly paused to allow for the conversation; as soon as the conversation is over, the portable Bluetooth speaker brings the music back to life.
