There are a lot of better options than the CX300, even at this price point.
The QuadBeat 2's that come with the LG G3 put them to shame and can be had for around $25 on eBay if I remember.
CX300 seemed OK ten years ago before balanced armature became standard/affordable…
I am a big fan of the MM30i - it has track control, volume control and a mic.
However I got some of these on special (wired, black/grey) for $18 USD:
