I'm a new 668B user bought from trio.

now i waiting for Canare L4E6S custom cable with 2% silver soldering and gold plated plugs

i'm considering to buy an amp below rm150 for the 668B.

any recommendation ? i often hear rock, pop and chillout music.

p/s: this is the first HP that i bought some enhancement for it

my HD668B with Canare L-4E6S Custom cable

SQ is improved with slight bass enhancement, and clearer mid and treble.

I got that from this thread. In my case, it is RM 75 for 2 metres.

currently i'm using Fiio E6 to amp my HD668B, and i can say the SQ improves not just being more 'live' and louder, but it become clearer, however it is depending on your EQ settings,though. IMO, the E6 is quite good if u are looking for budget entry-level portable amp.

How about HD 681 EVO? that one is balanced in bass, mids, and treble.

everybody is busy playing with their superluxes

btw, u oredy try d-i-y? myb u can just use normal screw..

dont know much..

u guys already tried tissue mod?

i used that mod on stock pad, and its quite comfortable to me

here it is



u can use face tissue which is soft to fold and can improve the pad cushion feel.

u also have options whether to put tissue all round below the pad or just half round.

full tissue mod will give u better comfort plus slight bass improvement.

the quality even better after fully burn-in.

the gap between the pad and the speaker is quite large, u can u can put thick fold of tissue like in the pic above.
i agree the pads are quite stiff, plus they were easily sweated after use for a long time

how long the time to fully burn in, depends on how frequent, and what type of song u play.

for me, i used everyday around 1-2 hours per session with lappy and mp3 player, around 3 sessions per day.

for songs type,i listens to bass-heavy songs, clear mid and high songs, and sometimes i play around with frequency tests video in youtube.

one song i remember is Astronomia-Tony Igy.

For audio quality, i think it does not matter, i have .flac, 320 kbps, 192 kbps mp3 to play around.

u will know the 668B is burned-in when u feel comfort with the sound projections. Because the early time u used the 668B, the SQ was not comfortable enough to hear.

i paid RM 75 iirc to one guy here in lyn, he were selling custom cables for variety purposes.

that cable is quite thick u know, the first time i touch it, wow!

then, after i got the cable, i bought an amp, FiiO E6 (Fujiyama) for RM110.

this amp got 4 EQ settings (treble boost, bass boost, EQ-3, flat)

what are your budget? personally i recommend sony mdr-xb30ex

it has good isolation, and it have small 'hole' for air out from bass

i used 668B for months, dont remember from when.

u can view post from me in this thread to see my 668B.

my 668B already burned in, i used custom cable, and used an amp.

yes, it do come with pouch, with 2 detachable cables.

yes

but u have to make sure that u dont damage the male part of connector on the headphone.

i used that e6, and i could say the sound improve slightly, but depends on the your audio file type (mp3 or flac) and how burned-in your hp.

e6 have 4 EQs aside from just increasing the volume. as i used 668B, the sound is more better with e6.

1) you could try buying portable amplifier. try search for FiiO portable amp. I think here in garage sales got seller.

2) you can burn it by playing music full blast for couple of days. later on you will feel the music quality is better. sound level i not sure.

3) see no 1. plus you can buy custom cable which is thicker than ori cable, which slightly improve sound. again, look in garage sales, price under 200

I ordered my cable from him. its quality is good. under Rm100 depend on what u want for your cable (it is custom)

for cable, see my post above yours (Post #698). I did shared a link to the thread selling custom cables.

for amp, like bro inv on the above post said, it depend on what your usage. For me, i just need a small, portable amp like FiiO E6. bought it for RM 110.
