Audio46's Opinion

Sennheiser has taken a balanced approach to their low end here. Neither stingy nor indulgent, the bass gives nice impact to pop music, while remaining tempered enough for genres like classical music. String instruments had impressive detail and articulation for a headphone in this price range. And listening to rock, the low end doesn’t offer much warmth, but the bass is super clean and controlled, avoiding bleeding into the higher frequencies.
