I have had my Nuarl N6 Pro for several days now and can share a few general subjective comments:
They are smaller than I had expected based on photos.
Fit is excellent; very secure and unobtrusive.
Connection is rock-solid. Nearly instantaneous pairing.
Imaging and soundstage precise and realistic.
Instrumental and vocal timbre nearly flawless.
Able to reveal subtle details in well-mastered recordings.
Build quality of both buds and case is superb.
Nits:
Buttons are rather difficult to identity by touch.
Easy to inadvertently press buttons when inserting.
Upper treble can be brash at times.
Intolerant of poorly mastered recordings.
Needs a quality app to fully explore capabilities.
Great impressions, mine are near identical. I am pretty amazed how poorly they handle some recordings. I too would like an app to add some low end to them. I found the N6 to be very similar almost identical but tuned with more bass and slightly less detail.
