Yes – the Cloud MIX Buds can connect to both the 2.4 GHz USB-C low-latency adapter and Bluetooth devices at the same time, but will only play media from the low-latency adapter in this configuration. If Cloud MIX Buds are connected to the low-latency adapter, they will not auto connect to previous Bluetooth devices.  

If the Bluetooth connection is currently in hands-free profile due to voice communication, this will take priority.

The Cloud MIX Buds can pair up to 5 devices via Bluetooth but cannot play media from multiple Bluetooth devices at once.
