Works great!
Works perfectly with my Audeo Marvel M90- and 2018 LG TV via optical connection.  Allows for both the TV external speakers and the optical audio to this device at  the same time.  No lag at all in the audio.  Once initially connected to the hearing aids the box will automatically connect every time the TV is on and you are in range (in the same room).  When you walk away out of range,  your hearing aids will chime as the signal drops out.  When walking in range they will connect with no indication.  Actually wish I could turn off the chiming.  If you walk in and out of the room a lot with the tv on it can be a bit annoying but other than that I’m very happy with the device.  My new hearing aids are a great improvement over my 6 year old previous hearing aids  and I’ve been able to get away from using closed captioning.  The LG TV also has a “clear voice” setting which also helps a lot.  But this is icing on the cake, for perfect audio.
