Great after burn-in

I bought these on a whim since there was a very good sale going on. I hadn't researched when I bought them and after pulling the trigger, read some reviews stating that the trebel was very dominant and was sibilant. When I received these, the packaging was very nice, the earbuds themselves were very high quality and the pouch that comes with them is very nice as well. I plugged them into my gen 3 ipod and low and behold, they were extremely sibilant and had overpowering trebel. I wasn't happy. I am not one to believe in burn-in, but thought, "what the heck" and fired up the Metallica catalogue at full volume and let it run for a couple hours. I then put a 10 hour pink noise vidio on Youtube and let it run. After this, I plugged them in. While still a little trebel forward, the sibilance was gone and they sounded amazing. So much for my burn-in myth. I have been using them for the last few hours with my Galaxy S4, a device I typically don't like the sound out of. With the CX890i's, the sound out of the S4 has gone from subpar to more than bearable and on my ipod these are fantastic. I am certain after some tie listening I will become used to the trebel and these will be 5 star worthy. 128 kbps MP3s are still sibilant, so make sure your source files are 256 kbps or better.

Would I recommend this to a friend or family member? Yes
