What is the difference between the Image S4i and S2m sound performance?
The S4i employs exclusive dual-magnet micro-speakers. By giving these micro-speakers larger diaphragms, the S4i delivers more output as well as category-leading musical accuracy and bass response. Klipsch believes the S4i sounds better than most headphones within the $100 to $150 range.
The S2m delivers superior bass response when compared to other models within the same price range, while also combining comfort and style. Like all Klipsch headphones, the S2m solves two of the biggest issues with all in-ear designs: they are extremely comfortable and offer a good seal for superior noise isolation—you won’t find these attributes anywhere else in this price range.
