    "THE best sports in ear headphones as far as fit and sound quality goes"
    Pros - very secure fit, excellent sound, with wide bass extension without mudding the higher frequencies, solid carrying case, excellent microphone
    Cons - can get uncomfortable after a couple of hours, not overly refined sound, cable sticks to itself (not tangle proof), microphone placement too low
    Got this earphones for the sole purpose of working out/biking. Tested out multiple sports headsets (similarly priced), from sennheiser and bose. They tend to sound better, especially than the adidas sennheiser which sound pretty bad for the money. Great bass and clear mids and highs (considering it is bass-centric). 
     
    It is not neutral by any stretch, but you have to remember they are made for sports and wokring out mostly, so they are perfectly tuned for dyamic songs, like hip hop and electronic music, which is what most people listen to when working out (hence the name, Sonic Fuel). For these genres, they work PERFECTLY.
     
    The in line mic has a analog volume control button, which is good since you will be able to modify the volume regardless what brand your phone is. The microphone is also very good, people on the other side of the line heard me clear.
     
    The downsides are, in my opinion, the cables which have a tendency to stick to each other, making them non tangle free. The volume/microphone module is placed rather slow, so if you wear them under your shirt when working out it's kinda hard to take calls. Also, it would have been a big plus if they were at least sweat proof.
     
    However they deserve a 5 star rating in my opinion because for what they are made, active wear, they are incredible stable in your ear, and are almost flawlessly tuned for the kind of music one listens to while working out.

    "Large but amazing"
    Pros - V shaped sound, isolation, durability
    Cons - Large, in-line awkward, fit
    Lets start off with the pros. When first out of the box they sounded great, good bass and slightly crushy highs but after a mere 10 hour burn in they sounded great, hard (but not thumping) bass and excellent no distortion highs. I mainly listened to EDM, house and hip hop and those genres sounded great in the ckx9is but vocal tracks from Ed Sheeran and Sam Smith wasn't at all shabby. Also, the ckx9is and great detail and soundstage versus the s4i rugged which i had previously and for the same retail price the ckx9is is by far a better sport iem.
     
    Onto the design and comfort, the only issue i found was finding the right fit as personally i do not like foam tips but was a nice addition and the c tip addition helps with isolation and fit as the earphones are large and heavy but does have adverse affects on small heads as because of its size, it pushed the tragus of my ear forward slightly. Also the in line mic is separate to the volume control of the device which confused me when i had the volume very high on my phone and was quiet in the iem. Also any slight movement of the slider or button would cause disruption with the channels (making one ear sound quieter than the other) which was annoying but a fairly unique feature. The l shaped plug was a bit large to fit perfectly with my iphone case but it did not affect the sound and the cable itself is very good but not fully untangleable.
     
    Overall a great headphone for its price range and would recommend to any sort of edm/hip hop listener
