Fantastic and thorough review. Thank you. I'll definitely have to check these out.

Thanks for the review. Just picked up the IE 40 Pro myself (the 40, not the 400). Sounds like the 500 is just a more refined version of the 40. Really like how these sound for just $100, coming from a JH13 Pro. Fun to have a Dynamic Driver IEM again after years with BA setups.

Useful comparisons to benchmark IEMs such as the EX800st and ER4XR. Sounds like a quality IEM but the cheaper models also sound like great value.

@XERO1 @Malfunkt @starfly Thanks! IE 40 Pro is an excellent IEM for the money, and yes, the entire Pro series have the same overall signature, just getting better in resolution and speed as you progress. My detailed IE 400 Pro review will be out this weekend. Wait for it!

Thanks, this review came in perfect time
