Phonak Marvel long range Bluetooth Transmitter

I recently purchased the Phonak Marvel rechargeable hearing aids. I understand that my new hearing aids are Bluetooth 4.2 certified. I also picked up two TV connector transmitters from my audiologist. These are fine if you are very nearby. I am someone who can’t sit still and tend to multitask as I am listening. I don’t want to be tethered to one room.

However I can’t seem to find a long range BLE or 4.2 transmitter. My goal would be to be able to be anywhere in my house or yard (hopefully) and receive streaming audio with decent reliability.

If you can help me find a 4.2 BLE transmitter that will meet the criteria of being compatible and long range. I am hoping for 100-200 metres, but I understand that with BLE the best I can get is about 100 metres. It’s not great but I can live with that. Can you make any recommendations please?

Class 1 Bluetooth range is 100m. Beyond that you could stream from your phone and take it with you.

I’m not clear how you would use BLE with the Marvel. It connects to devices using classic Bluetooth.

I have purchased two different class 1 transmitters and neither are compatible with the Marvel hearing aids. They have the range, just not the compatibility.

I don’t think Marvels are Bluetooth 4.2 “certified.” They work with many Bluetooth 4.2 and above phones, but I think getting them to work with other devices could be a challenge.

The Phonak users’ manual page 55 in the spec section simply states Bluetooth 4.2 Dual Mode

I have recently used an iPhone 5 and iPhone 7 with my KS8 HA’s. I can’t find much on what the KS8 are capable of, but there sure seems to be a difference in the reliability of the connection with the HA’s. The iPhone 7 which has Bluetooth 4.2, A2DP, LE, is much better at staying connected than the iPhone 5 which has Bluetooth 4.0, A2DP.

The Connexx App has a feature that shows your noise exposure during the day. Even when I keep the iPhone 5 in my pocket the exposure graphs keep dropping out during the day. The iPhone 7 even when I walk away from it in the house seems to stay connected.

As @Don said, the Marvels use bluetooth classic with the profiles below, not bluetooth low energy. It makes no difference if you get a bluetooth 4.2 or 5 transmitter. For the supported profiles, there is no difference.
