Can't belive the kanen ip808 hasn't been mentioned, this iems main focus is sub bass <100hz no roll off till 20hz , the sub bass from this iem is amazing.
It's a fairly decent sounding iem overall, soundstage is slightly above average , treble is crisp and clear , vocals sound good , the sub bass does slightly overpower the lower mids and theres a dip in the frequency response in the higher mid range which means at times the mid-range can sound a bit thin.
Also it needs amping at 32ohms and lower sensitivity its harder to drive than most iems, a portable amp like the ibasso d10 does the job fine.
At the cost of £6 the kanen ip808 should be in every bassheads iem collection.
