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.
