pl11 here. after burn 8 hour ...the bass = WOW...lol

I find that to happen quite abit with some brands of IEMs (especially those with generally lower QC, not pointing out names, but generally China made ones)

Try to request for an exchange if that happens. Swap the sleeve from right to left and see if its the sleeve causing problems or just the IEM's tip causing the problem. I believe the seller will allow an exchange if the IEM's causing the problem. Do remember as IEMs extend into the ears, even the tiniest out-of-range built, if not detected during QC will already cause discomfort while wearing it.

Well, I don't have my Atrios yet, but I chose it based on a lot of feedback saying that it has good quality bass without sacrificing too much clarity unlike most bassy IEMs. I'm not too worried, because I already own two cheap earphones, the PK3 and PL-11 that has thumping bass and good clarity. Surely the USD200 Atrios can't sound any worse than both of them

Well.....IMO

PK3 - Good amount of bass but lacking in clarity. I had to EQ Treble Booster to get a clearer sound. Frankly, the one and only time I've ever used Treble Boost. E5 amp doesn't do much, bass boost just muddies up the bass even more.

PL11 - Slightly less bass but much better clarity. Great synergy with E5 amp - bass boost on. A good overall IEM with better bass than average.

Hey need helps here..

got any IEM suitable for basshead(song like Akon, Flo rida etc)?

budget below RM 100~

n i want it better than EP630

Soundmagic PL11, JBL reference 220 or any other suggestions?

Do u audit the others b4 like Soundmagic PL11, JBL reference 220, and Sony IEM?
n where to find that JVC HA-FX33? thanks

Hey, thanks bro (for understanding ) . So, u guys trying to say JBL better in bass area, even compare to PL11?

Ok..how much the JBL? any LYN member selling it?life just fill a bit weird without IEM.though have a new can, still no subtitute for IEM.still need an ear plug .

ok.wow,thanks a lot bro.now where can i find the JBL?

Agree.but IMO,replace 830 for soundmagic pl-30,a bit more spending but better performance per value ratio.heard 830 got comfort issue

Haha, to me the EP630 is no where near the JBL xD You need to change the ear tips given to get better seal, I'm using IE8 ear tips on it, it improves the seal a lot Also IF you like the JBL SQ, you'll definitely like Sennheiser IE8

Female? 

JBL reference 220?
When I first time listen, I was shock.. Why an IEM got wow effect  
vocal laid back, cant listen clearly..
After burn in abt 80 hours, that wow effect not so heavy.. vocal come front abit but still lose to EP 630
however, if compare wif detail and bass, EP 630 lose alot to JBL
N one more point, JBL is open type IEM so when i use on LRT, i still can hear some noise..   

well can't agree more with u.830 does look exclusive.so does 830 a better buy than pl-30?

Owh, really? Then does 830 better than pl-30? I mean in comfort issue.

unfair... u can pm me ur pricetag... ( if it's really GOOD price... can help me to bring back to msia? )

yeah... SR80 really pawned SR60 u can read reviews in google...
