its "superlux"

Only 381 range is brought into m'sia market I think
  Please      and link the review here xD

Any cube C30 user here? How well can that little thing drive cans? What's the maximum impedance it can drive? 600ohm? Quite interested on that

I bought one chiplak MP3 for use on flight but that chiplak MP3... Not nicely insulated/isolate/whatever... It can't be used on plane due to interference at that altitude... All songs just can't play. Maybe looking forward to get C30 then can get some big ohmmmmm cans to listen xD

But C30 comes with an AMP built in. I thought we cannot connect it to external amp? Not very sure.

381F got distortion? Don't really notice it.

Offcourse every DAP got AMP inside.. if no AMP how you gonna get the sound from the DAP.
C30 use MAX9722 Opamp - 130mW per Channel into 32Ω
enough for 32Ω but if use with higher Ω, the output will smaller that's why need to have external amp.

Some DJ series headphone have up 1500mW input, with 130mW output from C30, consider really low. Need amp too here.

I can put volume to the max at C30 (volume 31) if I use with Philips headphone without any amp.

Even if I use C30 (full volume) + Fiio E11 (EQ 2, HIGH gain, full volume), my Philips headphone still can handle it very well.

Never try with any Superlux variant.

Nowadays more people get 669 or 668b
The 668b design looks more classy to me 

any hd651 user here? i want to know how is that headphone. thanks in advance.

just test 668b today, the detail is there,very detail. but sound harsh for vocal listening.i feel that the mid is totally missing,feel like something wrong..the sound run everywhere which unable to get correct position of the vocal.
BUT for the price under rm100,this headphone is bang for buck~

*just my point of view, cause i too used to Er4P sound....

hand itchy for a new amp, need more powah for my HD660

@nick67
I would go for 330/440. No solid reason. Just a hunch.

I've the 668B which is supposedly either slightly better or worse than 661, which is why 661 is not in my list.

Anyway, about the comfort, I guess it'll be like 668B. Not comfortable at first, but gets better as you stretch it.

currently i m no hippo groove , i m not sure whether the 381 will give me an upgrade or or not .hmm ,

thanks for the comment , will think about it , or get soundmagic iem   but the review rate 381 quite good.

Anyone link me to another Superlux seller besides Hellfire?
Wanna get Spuerlux HD661.

661 currently out of stock in msia. Will restock very soon with new colours
