SonaBuds Wireless Stereo Earbuds is the smallest and the most affordable wireless earbuds with HD audio and built-in microphone for taking calls. SonaBuds deliver 4 hours of listening time on one charge. And the companion charging pod provides additional 20 hours of play time. Enjoy non-stop music when you carry four earbuds with you. You will always have a pair of fully charged SonaBuds with you for those TV cliffhanger moments that you just don’t have seconds to waste for the earbuds to recharge. SonaBuds can be connected to two separate devices at the same time. When one of them rings, it knows which one is ringing. So when you answer the call, SonaBuds will automatically stream it from the right device. The built-in microphone will pick up your voice in crystal-clear quality.
