Upgrade Your Existing Bluetooth. Using this dongle effectively bypasses your built-in Bluetooth for a stronger connection to your headphones or speakers with fewer dropouts. It also provides access to codecs your native Bluetooth might not support, such as Qualcomm aptX Lossless and aptX Adaptive for CD quality and higher. In addition to 24-bit/96 kHz hi-res audio and lower latency, this dongle offers overall increased stability and longer connection distances compared to most device Bluetooth specs.

Smart Control App. This dongle works right out of the box but if you would like to maximize customizable features. download the Sennheiser Dongle Control app. Through the app you can view and configure active streaming codecs, try out different performance settings, and upgrade firmware.
