Actually the Zen was the only thing left when I purchased the Sarda. I was enjoying the Zen paired with the Mojo so much I was convinced to let go of my whole desktop setup and go fully IEM for work where I do most of my listening. My plan after selling my work setup was to purchase some open backs to listen to at home. Then a deal came up on the Sarda so I purchased it to compare to the Zen. The Zen held its own, but in the end I decided to let it go because the Sarda edged it out in performance. And I decided that I would go almost all IEM.
I will say that the Zen is the most premium looking and feeling IEM I’ve owned. That alone made me pause before selling it. It also had the best bass I had ever heard until the Sarda. But the Sarda has a reputation for being a bass king even among higher tier IEMs so no surprise there and the Zen again put up a good fight.
So when I sold the Zen I actually used the money to fund a pair of speakers for my living room. This is them!
