I was looking to purchase an IEM. I now that both of these have noise isolation. On the Shure website, it says that these "with good fit" provides up to 37 db of noise reduction. I did not find any information on the RHA.
I need a earbud with good good noise reduction. Do they provide the same amount of noise reduction? As I think both of these IEM might be around the same sound.
Any suggestions? Would you pick one over the other?
