Wireless Audio Streaming (w/ aptX): You can wirelessly stream stored music, music apps, and other content on your Bluetooth enabled smartphone (including iPhone & Android), tablet (including iPad & Android), laptop (including Windows & Mac), or desktop computer (including Windows & Mac) to the Soundcast VG1 speaker. In addition to supporting Bluetooth's standard SBC codec, the VG1 lets you enjoy high-quality Qualcomm aptX (compatible with most Androids) & AAC (compatible with iPhone) audio codecs, so you can enjoy the highest quality sound that is rich and crystal clear. You'll also be able to control basic playback functions, such as Volume Up/Down and Play/Pause from the VG1 speaker.

Immersive Sound: Two aluminum-cone drivers with butyl rubber surrounds deliver rich, clear audio; while a rear-firing weighted passive radiator provides deep bass extension.

True Wireless Stereo (TWS): True Wireless Stereo (TWS) lets you sync two Soundcast VG1 speakers together over Bluetooth for dedicated left and right stereo playback.
Rechargeable Battery: The Soundcast VG1's internal rechargeable lithium-ion polymer battery (3.7V/2900mAh) provides up to 15 hours of playback (varies by volume level). The internal battery can be recharged by plugging the included microUSB-to-USB cable into a USB port on a computer or USB/AC power adapter. A full charge takes about 3.5 hours (depends on power source).
