Proud owner of HD681 Evo.
Pro: The sound is superb. Bass is strong.
Cons: Sound leakage. Comfort.

Im interested in the HD681 evo.
I owned a superlux hd661 but it is not comfortable at all. too tight
Here i wanna ask
does the HD681 evo easily make your ear sweating?

I bought 681 evo a week ago, it not comfortable also, pads quite hard.
But 681 evo come with velour pads, this is cooler than pleather, but still hard, not sure is there is any 3rd party pads that really soft.

Where can i buy replacement headband for this item HD681 Evo? Any replacement will do. I dont wanna superglue it cuz i did that b4 but it broken again few months later.

Yes sweat a lot until the inside got your sweat if u open it up. Like a dried up salt water. More like sweat vapour...

Hi guys,

I bought a 668b after few hours in Star Pickers, rotating between 668b, 681evo and my (broken, plastic headband) existing can. I heard wider soundstage from 668b. 681evo has boosted bass and great for fun listening.

Between the 2, 668b is closer to my current target, Hifiman400s, so I went with them.

The padding is terrible on 668b though.

anybody got hd 685? care to share thoughts

I have it. Compare with M40x, HD685 has more bass and lower mids, but M40s has better details and separation.

Short review of upgraded cable for Superlux


Superlux is a Taiwan company which produces a lot of high CP ratio entry level headphones, especially HD681 evo. Its price range is only around RM100+, and comes with detachable cable. It is a very competitive product but I do think it can sound better. Currently the treble is a little bit dark. It has enough quantity of bass but slightly lack of details. Sound stage is very wide but the depth and height are not very clear.

So, I tried to play around with it and found out that STOCK CABLE caused the bottle neck !!!


After changing to "Uranus HP-SPOFC Teflon cable", the sound stage become very spacious. You can feel the depth and height of the space now. Treble is sparkling but not aggressive. Bass is tighter, clearer and more punchy.


I have another "Uranus HP-OFC Copper cable". The sound stage is not as wide as the Teflon one, but still much better than the stock cable. The strength of this OFC cable is the ambience of mids and bass. It is warm and thick, but clearer and more transparent than stock cable. You can feel that the singer is singing beside your ears. Sound signature is natural and comfortable for long time listening.

if compared to 681-evo , which one is gooding in bass? im a basshunter

I think the Evo overall sounds darker than other HD681 series. Treble is soften. The quantity of lower mids is fuller which can let you feel the vocal is more bassy.

How much for teflon set? I think it's time to come back to evo, been missing the soundstage

Hello .. recently buy my first superlux headphone HD681EVO .. i'm really noob in audiophile .. few days listening to this headphone via pc n iphone 6 .. my question is :

1) is this fon sound really slow?? .. i have to set volume to 100% at my pc n iphone when using this fon .. b4 this even 20% is more than enough using other speaker and earfon ..

2) i read b4 about burn in new headfon to increase sound quality .. what is the actual way to do the burn in?? will the burn in increase sound level too??

3) any sifu here can suggest any amp or other accessories than i can buy to get better sound .. budget below 200 can??

hope somebody can shed some light in this matter .. tq for your help ..

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

The 668B needs an amp to drive it. Just bite the bullet and get one. If you upgrade your cans, you'll still need an amp anyway.

U got any suggestion for 668b cable? Below rm100

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

thanks for ur help .. the burn in seem improve the volume .. no need to set to 100% anymore ..
now looking for other option to make sound uality even better ..
now hunting for affordable amp and custom cable as your suggestion ..
can suggest amp below 200??

Choosing amp will depend on how you plan to connect your amp to. Fiio amps are alright. I'm using e10k with the 668B and I'm happy with it using the stock cable.
