I will be trialling Marvel shortly. The compatability between Marvels and iPhone XS will be an issue for me. Other than that, can anyone help me with the following:-
- Any perceived difference between rechargeables and 13/312s in terms of functionality and hearing features? In theory, it should be the same, but stranger things have happened.
- Putting aside the specs sheet, any practical and valid differences between 50, 70 and 90 series that would make an upgrade meaningful? I need to decide on which one I will need and I am not looking to spend a bomb esp since my OPN1 is not that old yet and I have fallen for the marketing spiel way too many times (out of “I should not regret it later” concern, which doesnt really translate to real life differences later on)
