All user reviews for the Shure SE425

Headphones type ear monitor two channels
Atria unformed (unlike the photo)
Comes with lots of different foams.
The wire can be detached from the atria to be changed.
This thread, on the last ten inches, contains a small metal rod shape memory. We can therefore constrain the wire down behind the ear.
Its excellent.
What is astonishing is the isolation from the ambient sound. Once the headset is placed, you do not hear much else than what happens inside. So much so that I can add an ambience mic on stage to hear what I said.
