Awesome! They’re definitely underrated tips. So far they seem to be very well liked by the folks I have recommended them too as well. It helps that they’re much cheaper than something like Comply tips, too. 
The 100 step hardware volume button and 3 gain levels on Ibasso DC03 Pro is a godsend when you have supersensitive IEMs. Finally have lots of range in volume adjustment on Andromedas. The trick was to have the IEMs plugged in to the Ibasso before connecting it to the Android phone to get full dynamic output, otherwise phone vs dongle volume seemed to get confused and sound was lacking to my ears. Ibasso UAC app installed. Output impedance <0.12 means the frequency response hopefully isn’t affected. My Campfire Andromedas 2019 are 112,8dB/12,8ohm.
