The bass accuracy of the AKG K371 is excellent. They follow the target curve almost perfectly with only a slight overemphasis in low-bass which will give them slight extra thump, though it shouldn’t be overpowering and will be more felt than heard.
Also, their bass delivery varies noticeably across users, and is sensitive to the quality of fit, seal, and whether you wear glasses. The response here represents the average bass response and your experience may vary.
