Yeah, velour pads for K240 to be specific.. Since we haven't decide on a supplier yet, it would be great if you would help.

It's 3 months actually.. And I agree, less waiting and smaller hole is always welcomed.

Pitch leaking?

As for burn-in, I left it a couple of hours on my C30. After that I just use it. Can't wait lor. Love the bass, mids, vocal, treble, clarity and sound stage.

Thanks a lot for your effort.

Other than iamyuanwu, trio said that he found a supplier, but they're in the process of creating it IINM..

That's about RM60 per pair? Nice! But sadly there are only 2 in stock..

The described sound sig sounds like something that I'll like. How much is this new poison?

I can at least confirm that 668B is available at Jaben for testing/auditioning. Not sure about other models.

For buying, other than trio and one or two other LYNers, I know no others.

As for the recommendation, I guess the only thing I can say is that if you don't like bright headphones, don't get 681/668B. Other models, your guess is as good as mine, cuz I've only read reviews on them. Never tried them.

The headfonia review did compare 660 and 330. It's the only comparison I know.. Here's the link.

trio said it's like 668B level 2. No in-depth yet..

From a couple of posts that I read, the main difference is better bass and less airiness. More here.

While I don't think it's useless, for substantial improvements, it's as what the 2 gentlemen said.

Hm.. My own sock and tissue mod + ssyycc's cable:




At least now my earlobes are no longer being pressed by the pads.

iamyuanwu's mod is it? Yeah it is.

@Hitman: Great write-up on the 669.

I agree. Hm... Get Fiio E11!

AFAIK it's not rich bass, it's deep bass, or some would say B is for balanced. The 381 series best describes this where the 381 have rich bass, and its freq response is similar to what you suggested, whereas 381B have a nearly flat low freq.

@Invalid
I'm with MrJinggles on the 668B, though lacking in bass for me is more towards lacking in amount, where even a cheap Fiio E3 amp could fix.

Dunno really. Most of us here were just going to get one try them for ourselves. Should really help the comfortableness of the 668B, I think.

Btw, HD669 seems like the better choice if you're willing to spend an extra ~RM30 or so. So far all that tested the 669 says that it's better than 668B..

@MrJinggles
Love your new superlux sigs. Perhaps you can make one for future 669 users as well.

For a good amp, it's cheap. Why don't you go around and look for real expensive amp.

As for the Superlux amp, read here. Trio said if he's able to bring that in, it should be around RM300++, but that was back then; 30th Jan to be precise.

P/S: E11 is cheaper.

@zack_jr
It measures 43×94×140 mm and runs on 2 AA and still not portable? If you actually meant pocketable then I'd agree with you but it's definitely portable.

Regarding the holes, I would say most probably yes. It's a semi-open cans after all. Maybe you can try put it on someone else head and see if the leaked sound disturbs you.

@IsTheTime
Don't forget headfonia.

Personally 668B bass is good, just sometimes an extra bass is needed. I'd suggest to test 668B and E5 at Jaben, but then again, I wouldn't audit anything unless if I'm sure I'll buy something from them.
Malu ar test2 pstu balik tgn kosong. Lol.

As for whether to go for 681B or 668B, IIRC, after reading through this thread I pretty much gets that 668B beats any 681 series.

AFAIK they don't. But they do have a 668B around for auditioning purpose. At least they did when I went there last time..

668B is somewhat infamous for its deadly clamp, i.e. when you wear it, it feels too tight; even causing headache etc to some..

1) As what ssyycc suggested, just put it on something that's roughly the size of your head. The clamp should reduce over time.
2) Another suggestion is to stretch the headband by pulling the two earpieces apart, just like when you pull them apart before wearing it, only stretch it a little further. As the first method, the clamp will loosen by time.
3) Final option that I know is iamyuanwu's method. Of all options, this seems to really loosen up the clamp, but I don't where exactly did he put the grease..

Personally, I just use my 668B normally and sometime stretch the headband a little. I've used them for about a month now and the death clamp is no longer a problem to me.

Search this thread for it.

Anyway, this is Hitman66's impression of 669 along with comparison against 668B..

I suppose you mean 681 is more laid back than 668B?


@jblaze: I've only listened to 668B, so I can't comment on others. I'm using 668B mainly for music and sometimes game. It's great but sometimes I feel the need for an amp; for bass boost.

@jblaze
Happy to help. Btw, I think trio is talking about 669's different sound sig when plugged into different source.

There's this test done by hitman66, comparing the sound of 669 when plugged to an on-board sound card vs ooAoo SQ210a+.

Welcome! So, what's your impression on the 669?
