I’ve used Phonak hearing aids for years, and started using assistance for TV viewing with the Phonak Compilot II system, connected via the TV’s Optical (Toslink). When I moved over to Bluetooth aids, the Compilot system no longer worked. I replaced it with the Phonak TV Connector (V1). I had it set in Target to “Manual plus beep”, and it worked flawlessly, independent of the TVs speakers.
A few months ago I upgraded my TV to (UK) “Sky Glass V2”. This is a 4K TV, with built in Soundbar and Dolby Atmos. I find this TV excellent, but sadly it doesn’t have an optical connection. One of the HDMI ports is eARC compatible, but I’ve had no success with 2x Audio extractors I’ve bought.
This isn’t a major issue, as the TV’s standard sound is so much better than my previous flat screens. I’m sure having the speakers pointing towards me, instead of downwards on other TV is a major factor. I can hear pretty well unaided! I feel standard flat screens are the equivalent of your partner talking to you facing away from you! This TV does have Bluetooth, however, and I do have 5 pairs enabled. You can choose Speakers, Bluetooth or Both. The speakers volume is independent. There is lag, and I do have to “turn up the volume” to shift the balance towards the aids, but this generally works well. I have a Blue Ray 4K player. The lag is ridiculous with this (probably 400ms). I think there’s a compensator for this, but I’ve not tried it yet.
