so, i got a few questions.
im working on a project that is basically audiophile hearing aids. basically im building something similar to a reciever in canal hearing aid as a pair of tws iems. so, what im curious about is whether you folks have any advice on single ba or minimally sized multi-ba sets that would sit deep in the ear canal with a molded shell. i need the mems microphone i will be using to sit deep in the conch to get closest to natural pinna gain. so both small diameter and short length is important.
im currently looking at the rab-32257 with green filters for an er4xr like sound. but id love it if i could make something that has greater technical ability for critical listening and mastering as im a musician. anyway, any advice on compact options would be greatly appreciated!
im also curious whether anyone has info on the symphonium helios or hidition viento in terms of drivers. im curious as to what secret sauce theyve got to trade blows with 8+ ba or tribrid iems, other than the 4 way crossover?
lastly, im curious whether any folks have tried to use individual dacs for each group of drivers to create a digital crossover system?
