Having used the previous model of s-JAYS, which I may add were terrific until the wire frayed at the jack input, I am delighted to report that this new model represents a marked improvement in nearly every department. The sound quality is rich and solid on the bass and crisp on higher frequencies. I tested them on Mozart's Requiem to ensure it met my needs and it passed with flying colours. The only wire issues I suffered with the old model, which included the annoying split cable with a short earplug cable and extension, have been fully rectified. This model has the classic all in one cable which is great (if a design isn't broken, why try to fix it?) The cable is also made of much more durable rubber than the previous model, which can only be encouraging for longevity. My old s-JAYS lasted nearly 2 years and cost £50. These new ones are a vast improvement in nearly every way (sound quality was always top class and remains so). The most impressive aspect of these earphones is the fantastic price, 22.50! I can assure you that you won't find better for this price. Add in the included splitter, replacement filters (which last ages, I still have a set from my old earphones) and wide choice of ear buds for bespoke fit, you have an absolute bargain. I know I must sound like an s-JAYS marketing representative, but trust me, I am just a very happy customer who felt compelled to post a glowing review.
