I won't waste your time and just say, that even after almost 4 years since the release date "klipsch image s4" is still the best earbuds for under 100 (or maybe even 200$). Klipsch reference s4i is basically the same earbuds but with a few cosmetic enhancements, mic and also a remote optimized for apple devices. The only negative aspect of this product is the case, its too small and it takes too much time to cram in the earbuds. If you own an android based devise check the s4a model that is optimized for android. If you are looking for better ear tips you should check Comply TX-100 series foam Tips.
