It's no surprise the thing is going to sound like an earpod without proper seal. I'd be quite keen on a custom silicone sleeve for it. Until then, this product is NG for as I can't even fit it in (have only tried the medium size tip but have little hope the small one would work either given the size of the nozzle).
Marv, maybe you need to play a little more with the fit before reserving such hard judgement. Personally, I did like the naturalness compared to multi driver units, and especially BA type. You'll probably tell me I haven't heard a well done BA then but still
