and there could be several reasons why. I don’t consider the M13 T to be a “true” power aid though Phonak says its range is for someone with a “mild to profound” loss. Due to my hearing loss I pretty much need a power aid which Marvel-13 isn’t really set up for. I’m someone who feels one HA designed to meet all needs is some what of a crap shoot. Now I do think the Audeo M-13 could work well for someone with a mild to mid range loss, but not for someone with a severe to profound loss. Only good news was the incoming sound I received sounded normal and up to par with my old Widex HA’s. Where the Marvel failed badly was in background noise, where pretty much any program setting was a waste to try. I felt the HA’s some what function properly in autosense mode in quiet settings but since I obviously had it adjusted way up due to my hearing loss - it couldn’t handle noisy situations when set for “speech in noise”, “speech in loud noise” etc. HA’s struggled adjusting to back ground noise as it related to nearby speech from people sitting next to me to waiter asking what I wanted for dinner. Again I’m quite aware that my hearing loss does require a lot from a HA, but the M-13 T did not cut it. Being so small I also felt in someways the outer shell wouldn’t hold up long term. Maybe that was due to the “flimsy” battery holding clip that was (1) very difficult to open and (2) probably guaranteed to break during first year of use. I’m a disposable battery guy but if rechargeable batteries require less opening and closing of battery holder - then I’d go that route for less wear and tear on the Marvel. I also found the volume up/down button control on the Marvel to be way too small and difficult to locate. Maybe manual adjustments would of improved over time but I knew within ten days the aids were not working out. I also found it odd how you go from pushing a button for volume to pushing the same button for program setting. My Audi didn’t tell me you had to hold button down 4 seconds to manually bring up selected programs. But if you hold volume buttons down to long - the HA’s will completely turn off.
So I’m going to wait until the end of the year to trial the Evoke with power cell technology, with 13 battery. If Phonak comes out with a Power Audeo Marvel I might retry, but I had such a lousy experience with back ground noise I might also pass.
