I really like the Comet ( it took awhile for me to like it though). I wear them upside down with the cable going over the ear I found that to be the best fit for me and it allowed for the IEMs to get a good seal without slowly falling out. I also use the MEE BTX1 bluetooth cable that I use with them in the gym. For $200 they are a really good value for build quality. I think you can probably find IEMs that will do things better than these for the price, but I can’t speak on that due to lack of experience with IEMs… I have beatsx, cheap skullcandy bluetooth gym buds, and in the past I’ve exclusively used the Bose sports (still the most comfortable buds/IEMs I’ve used). I also recently was lucky enough to get a good deal on the Campfire Audio Andromedas, and I still use the Comets even though I have the Andromedas ( I do use the Andromedas more, they are similar to my favorite headphones HD800/HD700, but you can change the sound signature with cables and tips, due to it being such a sensitive IEM).
TLDR: Comets are a great buy, give them time (I think either I got used to them or they burned in because I like them way more now then when I first started listening to them).
