My Superlux HD681. Already done Frans's filter mod and recable (dual-entry). Plus spray some silver metallic paint.

Thanks. Actually already very satisfy with its SQ out of box. Just too free and hand 'itchy' wanna do some DIY.

SATO microphone cord. RM5 per meter. Half of the price of Canare that at 1st I want to get.

You mean recable? Actually not that hard to recable. But took me some hours. Some more due to cant make proper strain relieve on the limited space, I have glue it, cant open it anymore Didn't spoil the headphone already very lucky.

Will be a HD381F owner soon.

Just get my Superlux HD381F (about 25 hours burn-in), the sound remind me of Hippo Ten. The low, mid and high just sound natural. Bass is deep, smooth vocal, and have enough detail. Sound quality wise, it is nothing to complain. So relaxing when listen to them. The semi open design make it wont sound that 'in the head' like normal closed iem. Although it look cheap but don't sound cheap at all. Its fit well and comfortable. Easy to drive too.

Just my two cents, as a newbie in audiophile field.

Whether its comparable to those big company like SHURE, UE, WESTONE or not, I really dont know because I cant afford them and only have brief listen to them before at Jaben. But, this Superlux iem definitely wont sound like <RM100 iem .
