"High quality sound but poor fit"3.5 starson by carlconti08
Pros: The sound from these earphones is great. They have pretty good highs and mids with strong bass.
Cons: The fit for the earphones is too hit or miss for my taste. Sliding them in your ear and getting even just a good (not perfect) fit was too inconsistent. Also, the S4's eartips are made of very flimsy silicon that blocks very little noise.
Summary: I've owned so far, including the S4's, five different sets of in-ear headphones. I began with basic Sony MDR-EX71SL's whose sound and fit were decent in relation to my little experience with in-ear earphones, and they lasted me over a year. I then purchased a pair of Sennheiser CX300's that I really enjoyed listening to, but they irritated my ears so I couldn't use them regularly. I then received a pair of Shure SE110's for Christmas that I fell in love with. I graduated to SE210's when I lost the SE110's (only to find them a few months later). I recently had to send out my SE210's for repair and had read the reviews of the S4's when I decided to try out the S4's. I was very impressed by the sound. They made me realize just how much my SE110's and SE210's lacked in bass. At the same time I noticed less clarity from the S4's highs and mids, which was slightly distracting for me considering how long I'd been listening to my music with the Shure headphones. However, after some comparison, I do believe that the S4's have very good highs and mids along with the excellent bass, just not as good as the Shures, especially the SE210's. After wearing the S4's during various activities I would normally wear headphones, I came to decided that I hated the way I had to fit the S4's into my ears. The process of getting just a decent fit could take me up to a minute and then I would often find myself readjusting them shortly after and eventually pulling them out and trying to fit them in again. I will say that the headphones are VERY comfortable when worn properly, but the flimsiness of the silicon sleeves caused the silicon to pinch and fold as i tried to get them in my ear, either blocking sound or creating an uncomfortable fit. This challenged was also accompanied by poor noise blocking once the headphones were in the ear. Being on the subway was less quiet as when I had used the Shures. The fit was overall less secure as well. In the gym the earbud actually slid out of one of my ears while running due to the sweat (yes, I know, ew) and the jostling of the cord. In the end I found these headphones were not right for me. Luckily I had purchased them at Best Buy and could return them. I would highly suggest trying these headphones out, as they do sound great, but I would just make sure to keep the receipt and packaging in case you find the S4's shortcomings to outweigh its strengths.
