CrinEar Reference

Very well built IEM. Metal shelves and good shape fitting my ear perfectly. Sounds is neutral as expected. You can play with equalisation or leave it as is. Still decent level of bass and nice details. I like it

Does exactly what it claims to do. Sounds good all around, but might require EQ to taste if you are buying it for enjoyment and not work.

It is extremely neutral, this may present as boring or dull to many. However, this is an excellent base to adjust to your own taste with no noticeable flaws in the sound. Other IEMs in my ear tended to have too much bass, or a spiky treble that is difficult to fix with EQ. As far as I can tell, this has no issues and was very easy to adjust.

Highly recommend for anyone looking for a neutral IEM, but perhaps not to those wanting a more exciting listening experience out of the box.

Advertised as neutral and it delivers very well.
I have true neutral IEMs for stage use, but I wouldn’t use these for listening pleasure because they are flat as can be. These IEMs are neutral without being boring in any way.

In the past, I never would have thought that “flat” could sound so beautiful. And since I know that Crinacle never overpromises and I've trusted them for a long time, I ordered the Reference. They sound fantastic. Even with my aging ears, I can make out every instrument. Everything has its place and a delicate sense of space. I highly recommend the Reference!

Sounds very clear, lacking a bit of something in the mid bass.
Main complaint is the protrusion on back of the shell that causes pain above my ear canal openning. Inclusion of extra small silicone tip is good because it is the only one that fits me.
