Through all of my eye troubles long ago, from a detached retina to cataract replacement lenses, I learned to switch “eye dominance.” My left eye is for “close up” sight. My right eye is corrected for distance vision. This works very well for me.
By mentally de-emphasizing the “distance vision” in my right eye, I can usually get by without reading glasses. Looking up across the room, my right eye takes the lead. This happens automatically, without a thought.
I wear glasses when driving, to bring my left eye up to 20/20. The lenses in my distance glasses are getting scratched, so I’m going to make an appointment to get a new pair.
The fun part of an eye exam is after the prescription is getting close to correct, when the optometrist quickly flips the lenses back and forth in the phoropter. The question may go from “Which looks better?” to “Which do you prefer?”
That’s what it’s all about concerning so many things in life — what’s better vs. personal preference. In economics, this leads to discussions of cost/benefit analysis and diminishing returns. So, let’s make some comparisons.
I have the first and second generations of the Tangzu Waner in-ear monitor plugged into the porch’s laptop PC. (One of them is plugged into a USB-C DAC/Amp adapter.)
The most significant difference between the two products is how they fit. The Waner 2 is much worse in this regard, as I explain in my Amazon review.

Regarding the measured frequency response curves for the two products, they are very similar overall. Yet, as stated in the review, the W2 is significantly brighter sounding in the upper treble.
Which is better? Neither. Which do I prefer? Both. It depends on the music being played. Both products cost only $20, so there is no diminishing return on the price.
If you can stand it, I’ll have some more comparisons coming up, regarding images rather than sound. First, I’ll return to music listening.
The original Waner is better for Pop and Rock music, and the Waner 2 is my preferred pair for Classical music. Here are all nine of Schubert’s symphonies from the good folks at the Brilliant Classics label.
