kind of.. but very very gentle la.. and i didnt use my finger its a piece of rolled tissue
but compare to my PX100 which even moves when you blow the driver.. i tried blowing on the superlux,and find it rigid like a rock

and yea.. superlux really need to be amped well to perform. if you read most of the reviews.. there's one where the reviewer hook it up to a lavry lol and then say that he's amazed with the superlux

just bought a superlux hd 681 ...

i heard hiss when playing songs ....

plugged it into my computer built in sound card , AC97 ..

could this be the trouble ?

Could be your SC.. or the song itself. mp3?

yes, it hiss badly for new HD668B, u need to burn it in to the hell to get rid of it.

I have no issues with hiss since day one with my 681.. hiss comes from the source/hardware.
Headphone on its own cannot generate hiss.

weird.. cuz the HD668b i tested also got no hissing sound straight out of the box

hmm, have no idea, mine and my friend units both hiss gao gao when it's spranking new after a period of burn in the sound just gone.

PS. One tested on akm4396 driven by my speaker amplifier, another tested on TDA1543.

mine is tested the same on the akm4396 DAC as well.. but the sponge/foam cover in front of the driver is removed and the dunno_why_is_it_there sticker is removed as well .. but i doubt that removes the hiss.. but your hiss is treated by burn in so its no longer a problem already

Sq210A right? same with mine.
I tried it directly to the soundcard too, the bass seem like, a bit no energy. ~力不从心


then i tend to drive it with my F5, the sound is absolutely

hehehe yea.. its an awesome soundcard after some hardware and software tweaks
mine sounds a little too sharp but the bass is very tight and solid with the superlux ... but of course its run through canare L4e6s with switchcraft connectors

but regardless... if can tame the sharpness on my side, the superlux is definitely especially on my friend's maverick .. ooohlala

My HD681 also no hiss problem straight out of the pack. But I think this cans need amping to bring out their potential. I've tried it directly to my laptop...... the detail is there but the bass department was suffered a lot.

Tak ada umpphh...langsung.

Added on September 1, 2010, 4:19 pmMost of the time I listen to music using a desktop PC where from the on board sound card connected to my old PC speakers that have headphones out and then connected to fiio E5.

PC sound card>Old PC speaker>fiio E5>HD681. The SQ of this setup quiet awesome.

Now I'm looking for new sound card, maybe Asus zonar D1.

bring ur coming heatset come to me and i show u how good this can perform using my 10KG desktop amplifier.

lol I love to.....maybe someday we can arrange.

i am not sure whether hiss is the proper term ( not a audiophile here )

but its like popping / cracking sound / static noise when the bass reaches a high point and stays there continuously ...

Now thats different!
Thats 'clipping'.. you're overdriving the headphone! If thats the case, you need proper headphone amplifier..

i check some website from taiwan selling ti arounf $2400, around 230-250rm... T__T so expensive eh

Apparently, I've heard of some mentioned that it's more expensive to buy it in Taiwan than anywhere else. No idea why is that so.

Maybe it's like Proton.

but now malaysia where still selling it?

Instraco Sdn Bhd in Jalan Pasar is the sole distributor for superlux headphones. But unfortunately hd668b is out of stock. Other model maybe still available.

Recabled to dual entry. Cable held in place using bunched-up rubber bands---works as well any other cable strain relief.
Canare plug which is 2x as thick & almost as heavy as the Sony digital audio player (DAP).
Blu-tac behind the driver magnet.
Added rolled tissue paper in the earpad/cushion.
Foam disc and 'acoustic damper' paper removed.
A pair of socks over the earpad/cushion so that it doesn't become sweaty and sticky.
