Hello, I hope this sort of post is OK in this subforum... There is a headphone amplifier in a certain wireless device that performs completely awful with sub 10 ohm IEM's. Actually it performs bad with anything below 32 ohm I would say. I am not a technical guy myself, but I would still like...

I would google hearing aid desiccant

Fourte original was nothing close to being a linear IEM, if Blanc has the same main signature then it will boost and cut frequencies a lot. I see from the Crinacle measurement that original Fourte has a big midrange peak at about 700 hz and then a big dip at 1400 hz. Then boost at 2500 Hz and...

I do not own "high end" HP amps but lots of ones musicians or sound engineers use, either in their sound cards, mixing desks, "bodypacks" or other so called "professional" devices. These tests I have done are just out of pure interest if and how random HP amps do or do not affect the sound. But...

I like to make tests as I have the equipment to do so. Here is a pic of mesaurements of three very different amps driving U12t placed on top of each other, the differences are minimal at the best, the other pic is the measurements of U18t with the same three amps placed on top of each other...

I answer this too if you like. U12t has LID tech, U18t does not, so you get very different sounds out of U18t using different amps when U12t will sound pretty similar with different amps. With a proper amp capable of driving U18t you get most linear output of any 64 Audio IEM's with the U18t...
