Yuin OK2 - Initial Impressions

post #1 of 9
Thread Starter 

Just un-boxed some Yuin OK2 ear buds

 

with any phones, there is the initial few seconds, you put them on, and you either go.. mmm nice, or mmm.. not nice

that instant reaction usually says it all.. even if you have no idea why, they either sound good or they don't... these.. well didn't sound good.

 

to me that really says enough..   when i put on my px100's, i smile they sound good, especially for the price, and in fact if i paid the same amount for the ok2 and the px100, i would be much happier with the px100.. much much happier.

 

i had high hopes for these. I really did.

  Yuin receives high praises for them, and they definitely cost enough to create some expectations.

 

initial impressions:  I am not at all impressed, and I am furthermore disappointed, and a bit crabby about it so bear with me.

 

non existent bass, not nearly enough for my taste.  no that's not accurate.. not enough is not the same as simply not there... the bass on these is simply not there.. not even close to sennheiser px100 or klipsch x10

rolled off highs even with the treble booster on my ipod I'm not thrilled

mids are nothing special. a bit of resonance/muddy sound

 

sound stage is nothing special

 

ran a sine wave on these and confirmed musings... almost no response before approximately 100 hz, and basically everything past 2K needed a boost

 

as everyone says, ear bud functionality is useless. tried every tip with every shaft... nothing fit even close, definitely not comfortable or even usable, nor did sound quality improve in any way.

 

I will compare these to my px100's which i paid $35 for vs $130 for the ok2

px100's win in every way.   much better bass, mids and highs and overall better sound in every way

same with klipsch x10, there is really no comparison tho the x10..

 

also tried these with an amp.. no improvement...

 

 

I will be returning these..  frankly even if they cost $35 dollars i would probably return them.  i really wanted these to be the solution i needed for portable non noise blocking, ultra small headphones.   guess its px100 for life since nothing ever beats them except full size cans and iem's.  ill have to just deal with the hot ears in the summer temperatures. 

 

i am actually dumbfounded that the ok2 receive good reviews, and cost what they do. 

 

there's nothing quite like the anticipation of new headphones, and the disappointment of sub par sound quality.  bummer.

Maybe there's something wrong with them?  My PK2s have bass.

Update:

 

i just unboxed my new sansa clip+  and it has a custom eq

 

the ok2's sound a lot better

still not as much as i would like them to be overall, but better... definately not worth the money

still considering a return

 

 

on another note...sansa clip+  FTW this thing rules!!!

I'm confused. Nobody ever said the OK series have bass. They're good, in a way, but that doesn't necessarily mean that everyone will like them. They have their own characteristics, and in this case, those characteristics simply don't suit you.

 

If you want bass (quantity) from Yuins, you'd have to go to PK3s. Or straight to PK1s (with added expense for a decent amp).

 

Or maybe try burning them in first? The first few seconds, even hours, with a headphone can't tell the whole story. Some (except probly BA IEMs) earphones need burn in.

^^ Seconded. Burn-in sometimes help really the sound. Judging by the fact that these are expensive (relatively) earphones I doubt they can sound soooo bad as you describe.

 

For instance I do not like the sound of the RE0 as I find they have less bass and recessed mids. However they are still great earphones with amazing highs and can really bring out minute details in songs. Its just not what I look for in a earphone.

 

However your description is of a really cheap earphone which seems odd. So try burn-in for 10 - 15 hours and see if you face any improvement. If you don't see any improvement after 10 hours then in all probability you are not going to see any more improvement period.

To me there is a difference between preference and bottom line sound quality.   to me these fall into the category of just dont sound that great, more than they fall into the dont fit my taste category.  Im sticking with my description, because its still ringing true after some burn in

 

their low mid and bass response, or lack there of is what really gets me.  the fullness in the music is just not there. 

 

Granted, they do sound better than most cheapo stock earbuds, but again, not good enough for me, and certainly not $130 good.

 

the simplest way to compare is to rehash the px100 comparison.  the px100 simply excels in every way, and they costed $35.  I listened more today and just found myself dissapointed. 

 

Still heavily leaning toward a return with these.

^^ If you have had some burn-in and still dont like it then just return it. If nothing happens withing 10 hours of burn-in then nothing is going to happen after 1000 hours.

 

Its obvious the sound signature is not to your liking so take advantage of the return period.

I think you should definitely return the OK2s, and get another type that fits you better. You and I both know that you will regret it if you don't :)

 

You know what you like: the PX100s.

If I were you, I'd find reviews on PX100s, see what words people use to describe the bass on the PX100s (because different words actually convey different meanings - quality vs. quantity of bass, for example. You seem to want quantity. OK2s bass has good quality, but not quantity.), and then I'd find other earphones which have the same description.

 

I'm sorry if I seem to be opposing you a lot here. It's just that I don't want people read this thread and get the impression that the OK2s have worse sound quality than the PX100, because that is not true.

You are simply looking for something that the PX100s have, but the OK2s do not (i.e. bass quantity).

 

I can totally understand your viewpoint, though. After all, if the sound doesn't fit your tastes, it wouldn't sound good to you, would it? :)

what you are saying makes sense

 

I sent them back today.

 

I dont feel like you are "opposing" me or like we are arguing.. we are both entitled to opinions

 

anyway, the most important thing you said was the last line... if it doesnt fit my taste, it wont sound good to me, which is really the bottom line. 

 

next up will be either the sennheiser omx980, or the blox tm5... wish there was some substantial reviews on either of them...  and wish the blox were even available, and wish the omx didnt cost so damn much... geesh... anyway.. i digress

 

the ok2's werent for me.   for my liking   the mids were pretty good, the bass and highs were not...
