As a 2-in-1 adapter, it not only transmits but also receives, both using the standard Bluetooth 5.0 and is backward compatible. Switching between transmit and receive mode is possible with a toggle switch. Pair the Oehlbach BTR Evolution 5.0 with two devices and enjoy double CD quality with aptX HD. With low latency functionality and a delay of less than 40 milliseconds, you won't notice the wireless transmission and can fully enjoy music and other sounds just like with an Oehlbach cable connection. It sounds great at home and looks good in any home with its elegant, high-quality design available in two colors.
