Here's why:
* "Brennan" is not specific enough: Brennan could refer to various things. Do you mean a Brennan internet radio, a Brennan CD player, or something else entirely?
* Bose wireless speakers have various connection options: Bose speakers might connect via Bluetooth, Wi-Fi, or a 3.5mm jack.
* Connectivity depends on the Brennan device: To know if your Bose speakers can connect, we need to know how your Brennan device outputs audio. Does it have Bluetooth, a headphone jack, or a specific digital output?
To help me answer your question, please provide me with more details about your Brennan device, such as:
* The exact model name
* The type of audio outputs it has
Once you provide this information, I can tell you if your Bose speakers are compatible.
