I recently purchased Sleek Audio SA1 from Amazon for $40. I loved the sound of those but there was an issue that I couldn't get them to stay in my ears properly so I had to return them. They had such a lovely unique sound that I liked a lot. There wasn't huge bass but mid-bass was more than awesome, mid range and treble had a great detail. Soundstage in SA1 was also very good for me. SA1 had switchable bass/treble ports and I used the bass ports. Therefore, I wish to get something close to their sound.
 
Currently I listen through Brainwavz Beta and their sound is OK, but the SA1 was so much better that I am seeking for an upgrade. Brainwavz Beta's sound is too mid-based for me, bass and treble are both very limited on them. I have also had Bose IEMs but they were worse than Apple Earpods for me. I remember I have had some ~$50 Marley earbuds and some cheap Logitech Ultimate Ears too but either of them haven't been too satisfying. I listen directly from iPod Classic's headphone port and I don't really care if the headphones have mic/controls or not.
 
I have no idea what could have made SA1 so unique and great for me. Could it be the 6mm driver since it is only IEM with 6mm driver that I have heard?
 
Only suggestion for myself I have JBuds J6M because of their 6mm drivers and similar shape to SA1 but I cannot find any reputable review for those.

Anyone have more suggestions for me? I listen mostly electronic and pop music.
 
 
 
In the end, I ended up with Monster iSport Livestrong earphones. I can get comfortable fit with them without using the SportClips at all, and the sound is good enough for me. They are pretty bassy, and I like the big bass of these, mids are good too, highs are a little lacking but still decent. I think I will go with these for a while now.  

Heya,
 
Brainwavz M5
 
Very best,

Brainwavz M5 looks like a good option. I wonder how Brainwavz M5 compare with Brainwavz R1, which is in same price point, but has dual dynamic drivers? Brainwavz M4 is only $10 more to M5, is it worthy upgrade?

I found new IEMs for my consideration, MEElectronics A151. Found multiple glowing reviews around internet and balanced armature technology is very interesting to me.

Anyone got thoughts about these?

Bump

I'm now wondering between Brainwavz R1, MEElectronics A151 or A161.
 
I'm listening mostly electronic or pop music. Anyone got any idea which one should I choose? 
 
 
E: I got good deal on A161 in Amazon Warehouse Deals so I placed an order, I wish they are at least near as good as I hope for. I will post later how I like them. 

Try checking out this IEM shootout by CLieOS:

SoundMAGIC PL-50/ E-30 are other good options

I don't like the sound of MEElectornics A161 too much. Soundstage is really tiny and bass is very weak in these, a lot weaker than Sleek Audio SA1. Mids and highs are clear and good though, and the build quality on A161 seems to be pretty good. I return A161 to Amazon upcoming week. 
 
I really like the spreadsheet that zamorin posted, seems to be really helpful. I checked out and Brainwavz M5 is on really good spot there too. Therefore, I just ordered Brainwavz M5 and Monster Gratitude (since they are up there for really good price). I will compare these and hopefully either one of them is good for me. 

Woah, you ordered 2 IEM's? How much did you get them for?

Total price for both was $87.76 (M5 $36.5, Gratitude $51.26). I like Amazon because I can just return either one I like less with no questions asked.
