TrueWireless technology supports a truly wire-free listening experience, and is designed to deliver more robust overall connectivity when listening to music, an easier pairing experience and balanced power distribution between blafili XLR units for longer usage time.
Battery or DC-powered ( Power Adapter NOT Included )
Charge the blafili XLR using a USB Type C cable. You can charge it on the go with any USB charging port (even USB wall adapters) for up to10 hours of use per charge.
Plug-and-play USB DAC Applied
blafili XLR supports up to 16bit / 48kHz and allows you to listen to all types of high-quality sound sources through a computer just by connecting a computer and USB-C cable.
