I’m wearing these right now. They do go in deep into the ear, the batteries at least for me last about 4 days. Yes they are disposable. The sound is… interesting. I am a totally blind user, I get incredible localisation from these. Meaning I can hear in front, side to side, behind and even up and down because they go in deep enough that they use your natural ear structure to help with sound imaging. The problem for me at least, is speech in noise. I have no problem with speech in noise normally, but with these babies, because they have omnidirectional mics, if you get in a loud place, everything near you gets massively amplified and then speech becomes very hard to process over the overall sound roar.
You can make speech in noise programs to deal with this somewhat, but for me, I don’t want to take my environment away because then I lose my world perception, so I try and avoid these if I can.
I’m on a trial with these at the moment, I may end up keeping them but still figuring this out, trying the Widex allures soon as well, totally different style.
be aware, very little control is possible with these devices. You can control volume up or down, not both. meaning you can go 1, 2, 3, 4,5, or, 5, 4, 3, 2, 1. I have mine on the up setting 1 to 5. You can do that for each ear.
You can also control the program, you get 4 to choose from and your audi has to set these all up for you. Each program has its own memory for volume as well, so you can set program 1 to volume 3 manually, then go to another program, change that program, come back to your previous one and it remembers where you are.
There is no streaming, no blu tooth no other kind of connectivity on these. If you want a change, to the audi you go.
They are a really interesting little device. I’ve not decided if they’re quite right for me yet but they are certainly an interesting option.
