#136 Ruviest Viola: $280 Ruviest $280 eBay
Pros: A dynamic, planar and bone conduction tribrid at $280 with a preference score of 80. Bass reaches 20 Hz and the midrange stays within about 1 dB of target, and it ships with a balanced 4.4 mm cable.
Cons: The top octave runs 4.9 dB hot with a 7.8 dB peak near 11.5 kHz and a 4.8 dB dip near 6.1 kHz, so it can sound airy but uneven. It is sold only from the maker, and the score rests on a single measurement.
Is the Ruviest Viola right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 80).
- you want sub-bass rumble that reaches down to 20 Hz.
Skip it if
- you want the best value: the higher-rated QCY HT05 MeloBuds ANC costs about $246 less.

Frequency Response
How the Ruviest Viola measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
