Have the Monarch MK 2, Timeless, SA6 and B2. Monarch is better than everything else I listed, but the gap is not that big between these IEMs in terms of tier. They're all very good for what they are.

Monarch is very natural sounding with a decent emphasis on bass.

SA6 with symbio W tips sound pretty close to monarch. With original tips, their BA timbre is more apparent. They're smooth.

B2 is a little cold and thin. They're good for listening to podcasts but I usually have to turn the Dusk EQ on for music. Even then, it can be sometimes sharp to my ears.

Timeless is fun.
