I love these little beasts. I pair them with my goto player the Colorfly C3 (Hidden Gem) -   If you have a good source track these little  iem's shine - the sound is pristine and crystal clear - They have a lovely wide soundstage way out of proportion to their size; The Bass is a little weak but the high and mids shine. The only downsides to this are poor isolation (fixed by swapping for better buds) and the weak bass - but even turning the adjustable side bass boost dials just muddies the presentation a little. Then again I'm not really into...
