The ability to stream audio to both Bluetooth headphones and wired soundbars simultaneously is a boon for households with different listening needs, such as for those with hearing impairments. On the downside, the device requires a power source and is not battery-operated, which might limit its portability.

Also, the setup can be a bit tricky for those not tech-savvy, especially with regards to ensuring compatibility with TV audio formats like PCM.
