So I personnaly confirm that IKKO OH1 are incredible earphones, sound and construction hit above its price range IMO
Here, its really about lower end lively and well resolve presentation, look like I never listen to bass line the way I do with OH1, every single bass note have precise rendering and weighty presence (not in a boomy way).
This and the great imaging and overall smooth treble make them stand appart. I prefer them over BGVP DMG wich feel more congested, yet more detailed as well.
My review is up on headfi and on
No BS Audiophile.
