Hi, thank you all for your suggestions....
His problem is not so easy to solve, as it involves finding the right balance between sound quality and ergonomics
I'll try to explain better...
If you don't understand me, let me know, 'cause I'm Italian and I'm not using my native language....
The IEMs supplied with the transmitter do not satisfy him, due to the poor response to low frequencies (distortion)....
We did a test with the ones I use, with which I feel comfortable both in terms of comfort and frequency response.
I use the FCS11B (tech specs can be found on ineargear.com)
these are normal dynamic IEMs, they simply have a larger driver (11 mm)....
As I expected, he was fully satisfied from the point of view of the frequency response (these are IEMs created specifically for bassists and drummers), the problem however is the comfort, as due to their size (slightly larger than normal), they don't fit well in his auricle, and make him feel like they're always slipping out....
Hence the problem of finding the best compromise (including price, 'cause I don't think he is willing to spend $1,700)
