Phonak Sphere or Oticon Intent?

Whether this ends up being more effective than using, say, NAL-NL2, is a matter for debate.

Only NAL-NL2 and DSLv5 (and soon NAL-NL3) are proved independently and objectively that they're efficient for providing audibility of speech cues. Proprietary algorithm has papers only from manufacturer.

For what I know, it isn't possible to directly verify prioprietary algorithms like VAC or APD in REM - they need workarounds.
