Emre, it’s been a couple months since your post - so I don’t know if you found an answer to your questions. I am by no means an expert here, but I did sit with an audiologist a few years back who swore he could fit me with Lyrics. (My own aud-guy was not available, so in desperation I sought advice from a newbie.)
Well, he told me that once the Lyric is placed (deep in the ear canal, right up against the eardrum), it sits there until you need a battery changed. When that time comes - and you better be proactive, going in SOONER rather than waiting for the battery to DIE and then the aid sits like a stone in your ear), you need to go back to the audiologist to have them remove the aid and insert a pair with fresh batteries.
Right away, the deal was a woodchuck to me. Who would risk having a battery die in a device countries away from help?! I think you need a device to even remove & insert the aids. Plus, sitting so deep in the ear canal - at least for me, having had 2 bouts of otiitis - it seemed way too risky. If I was to get an allergic reaction to the aids way in my ear canal, it could be devastating.
Also, my loss profile seems WAY too much for Lyrics! Again, I’m no expert, but I can’t imagine trading off cosmetic looks for poor performance on me. Therefore, I shook hands with the newbie and got hella outta there. When my aud-guy returned to town, I got right in and subsequently was fit with a new pair of ITEs.
I think that “practicality” as well as health & ease of use of these Lyrics has to be measured in the equation before you commit to buying two pairs of them. In fact, BTE (or ITE, as with Oticon Opns) may be a much easier route in the long run.
