Great upper treble, but its overall tonality isn't perfect.
Youtube Video Summary

Softears RSV brings a 5BA recipe with a shell that’s handsome but larger than average, featuring a recessed 2-pin that can fuss with some cables. Comfort is generally fine, yet the size and wide body may test smaller ears. Sonically it’s a neutral-leaning tuning with clean mids and polite highs, but the presentation trades off texture, sub-bass weight, and upper-air sparkle. Stage feels spacious, extension is more average, and while the technicalities are solid, the current crop of mid-fi monitors has pushed beyond what this 2021 design delivers.

Stacked against today’s options, RSV gets pressure from several directions: Elysian Pilgrim hits harder down low with greater perceived clarity; Supernova offers a more natural tonality and better sub-bass; HiSenior Mega5 EST graphs similarly but adds a touch more air; even value picks like a “super mix”/EM10-style V-tune bring fun, slam, and engagement. RSV remains easy to pair and its upper-mids are tastefully set, yet vocals can feel a bit soft—more “fun and cozy” than pristine. At typical new pricing around the mid-$500s it’s tough to champion; catch it closer to $350–$400 (or a good used deal) and it becomes a very enjoyable pick for those who prize smooth mids over maximum bass grip and airy bite.

Unique tuning, but the switch would be better in the mids or bass.

Solid pick at used prices for those wanting a neutral sound with hint of sub-bass oomph.

Excellent balanced, all rounder sound signature with natural tonality, vocal reproduction is particularly pleasing.

Hint of darkness in upper registers affecting overall sense of resolution, bass texture could be better.
