looking for anyone that has tried or is using in-ear-monitors and a parametric or graphic eq for music performance (musician)

Hi, I am looking for anyone that is using or has tried using a set up consisting of a hardware parametric or graphic equaliser and a pair of IEM, instead of their HA + streaming dongle.
Please, I am not looking for HA brand advice. I wear Phonak P90 and currently use the streaming dongle for listening to my electronic drum kit and sequencer, the sound quality is excellent and ZERO noticeable latency. I believe the P90/streaming dongle, even though giving excellent results are not built for the rigours of a live performance setting. I am aware of a product on the market of which includes excellent IEM and an app with a level of eq processing for the purpose of which I mention (musicians), but the cost for me is prohibitive (IVO $1500+ aud), which brings me to looking at the simple configuration of an equaliser of some sort and IEM (IVO under $500 aud). I don’t want to be wearing over the ear headphones on stage.

I can’t help with your specific IEM question, but I’d bet the musicians at TheGearPage forum could. A vast, active haven for expertise/experience with music gear of all sorts…

Hi, try Wiim Pro Plus or Topping DX5 ii - these are DAC/Amp devices that offer 10 band parametric equalisation. They are limited to +/- 10db on the equalisation so wont have the headroom that your hearing aids have, but they will compensate to some degree for your hearing loss.
The other option is Apple Airpod Pro 2 as they provide equalisation - lots of info on this forum as to setup.
All these options come in under US $400
