If you are looking to get thumping bass out of a pair of in-ear monitor headphones, you definitely want to get yourself a pair of dual dynamic driver earphones such as the AudioMX EM-S4, which boast 10 mm and 6 mm coaxial drivers in each earphone!

The AudioMX EM-S4 dual dynamic driver IEM come with a hard clamshell case to protect the earphones from damage under normal use. 

The AudioMX EM-S4 dual driver earphones have a simple design with a nice white silver colour, which look quite stylish when wearing them on. 

The AudioMX EM-S4 dual coaxial driver earphones also come with a built-in microphone for hands-free calling.

The ear tips fit nicely inside the ear canal, while the rest of the ear piece fits snugly inside the recess of the ear so they don't stick out, making the AudioMX EM-S4 earphones comfortable to wear even when laying down.

The AudioMX EM-S4 earphones are not your standard earphones as they also come with adjustable ear hooks that keep the earphones nicely securely inside your ears.

The sound produced by the AudioMX EM-S4 dual dynamic drivers is pretty good with crisp highs and mids and really deep thumping bass.
