I have the lyric fitted and, for me, it works really well. No real complaints apart from the price (£3’000 per year in UK) and you can actually see them just about sticking out and the colour of them is … bright yellow and green!! What is that about??? That said, you have to look closely to spot them and, as I say, no other complaints. I have only had them 2 weeks though.
I am thinking of changing to Soundlens simply because Of the price but, as I write, I am not sure whether they will fit my ear canal.
By the way inn UK there is a charge for the trial of lyric - £95 per ear.
