Recently, I started listening to music while on the move and decided to go for IEM because of it portability and isolation. As my budget only allowed me to get some entry level IEM, my priority is getting the one with most value. During the course of my search, it narrows down to three IEMs. They are selling at not more than RM60 each at the moment. Inspired by ClieOS review, I want to share my experience and hope to get some comments and feedbacks.
I have burn-in all of them for around 100 hours before started listening and used small silicon ear tips. I ripped Michael Jackson King of Pop CDs into 320kbps MP3 and randomly listen to them with a laptop. I only listen to them myself thus this findings are only my personal feeling and experience based on my setup and it might be different to others or might not be accurate. This comparison is subjective and the values given are relative to one another.

FX33 (KM*)
Bass: 7.0
Mid: 5.0
Treble: 6.5
Clarity: 6.0
Comfort: 7.0
*KM = Kramer Mod
Like – Good bass, sounds clearer, good build quality, customisable treble.
Don’t – Only satisfactory mid, need to be modded first (though it is not difficult but not revert-able).

JBL220
Bass: 7.0
Mid: 5.5
Treble: 6.0
Clarity: 5.5
Comfort: 7.0
Like – Good bass, more balance sound quality, good looking design, the JBL (a pro audio brand?).
Don’t – Microphonics (can be minimise when wearing its cable over the ears).

PL11
Bass: 6.0
Mid: 6.0
Treble: 5.0
Clarity: 5.0
Comfort: 7.0
Like – Bass quantity, clearer mid, easier to drive with FiiO5, comfortable to ware.
Don’t – Muddy bass overshadow part of its sound, only satisfactory treble, difficult to see the L and R markings (for left and right pieces).

Generally, I feel all three have warm sound signature but excel differently at clarity, bass, mid and treble. FX33 (KM) is more analytical, JBL220 is more balance, PL11 is more bassy among these three. The above impression may be a reference to ones preference though differences among them are small but noticeable (I am no pro). Although I rated FX33 (KM) and JBL220 bass at the same value but they are different kind of bass, I do not know how to descript the differences. I believe these IEMs sound quality is better than most stock phones and might be better than some expensive ones.
I hope to upgrade to a more valuable IEM eventually but this would not be prioritised. I think these 3 are good for any audiophiles looking for an entry level IEM. Ones who like bass would not go wrong with any of this value IEM.
