If you're looking for a smooth and engaging hybrid that feature powerful bass, a full bodied midrange and well extended exciting yet smooth treble then Earsonics Blade is a strong option in a crowded market. If you're a Earsonics fan then this one should be a no brainer if you want the house sound with extra power in the bass and a clear step up in build quality. If you're looking for a snappier, punchier hybrid from Earsonics then check my Stark review.
If you’re looking for a fun IEM with sound technical foundations that you can listen to for hours at times without any fatigue, then the FIBAE4 is definitely a must own in a collection especially in its price bracket! If you’re looking for fun tuning with more bite and a snappier attack then there are a few mid range IEM that could suit you more like say Earsonics Velvet v2 or - more pricey - the Earsonics Purple or Campfire’s Atlas.
