So, I've now ordered both the R1 Zenith (today) and the R2 Aten. I've never had an open backed IEM, so I'm not sure what to expect. But, on doing some research, it does sound like they're not good for loud spaces or open offices. Does that sound right?
I received my Zenith only a few days ago. I have nothing but positive love for it.
I usually keep them open. I find the surrounding ambient noise from outside gives it an extra airyness in the soundstage. I thought it would dilute the bass and sub-bass, but it hasn't been the case. In fact I have chosen the pink filter to bring it down a bit. I like the extra sparkle that it has with the mids and highs.
I would close it in a quiet room if it could annoy people, although the sound leak is not as bad as OTE planars.
My concern before I got them was I bought headphones for the first time before demoing. I couldn't stop reading the reviews and comments so I knew I had to try them.
Have to say I am happy I got them. They actually set the bar quite high for my next headphone consideration.
I would love to try the Aten. Let us know what your thoughts are on them
