I did a 30-day trial with Marvel M-70R and was pleased with them. I took them back to get the disposable battery version which won’t be available until sometime in February.
I opted not to get rechargeable because my wife and I travel quite a lot. Sometimes it takes more than 24 hours to get from our house to our first hotel. Being away from the charger for that long is quite chancy since Phonak predicts only 16-24 hours battery life with the rechargeable.
For example, in May we will be going to southern Italy. We will need to leave our house around noon to drive to the airport which is 2.5 hours away. With a late-afternoon departure and two intermediate stops, we won’t reach our destination until 5:30 PM local time the next day, or 11:30 AM here. Allowing an hour to reach the hotel, that’s over 24 hours.
Disposables for me, for sure.
