As far as bass goes, I would say that the PK1 offers about 25 percent more bass at this point.  Maybe a bit more.  Certainly much better than the first day I pulled them out of the box.

Ya, that's probably pretty close.  Obviously just a guess, but it's definitely a noticable difference.

I have to say that I LOVE the PK1's and they have definitely changed.  I wasn't happy with bass definition in the beginning, but they just keep getting better and better.  I don't know how many hours I have on them but I would guess around 80.  And I bought the PK3 at the same time I bought the PK1.  I think the PK3's changed more than the PK1's.  I really didn't like the PK3's at first and definitely not as much compared to the PK1's new out of the box. (PK3 sounded very rough at bass, mids, highs.) But I sold them to a friend at work and told him to burn them in a bit and see if he liked them for the money...I knew from RE0 that the sound could really change.  Well, he bought them from me right away and I keep checking in with them and comparing with two tracks I use to test...THEY IMPROVED drastically.  Now, I would say they are pretty good at $40 and recommend them as the way to move from stock Apple or other DAP phones to my friends.  Others in the office have liked his PK3 in comparison to their stock buds- they have talked about buying several in one shipment together.

 

Also, I just have to say that I love the PK1's enough to buy the TTVJ Slim Amp to drive them.  It's on its way and I can't wait.  Much love for the PK1's and I really feel they lost an initial "boomy" quality.  The RE0's really changed as well, just not enough to fill in bass to my liking.  So I returned them after about 50 hours of listening and burn-in plus a loose left channel wire into the plug.

 

After reading that the OK1's are not as full throughout the lower end, I haven't wanted them in place of my PK1.  Instead, I am waiting for iems to round out my system. My 2 cents.

 

I'm a burn-in believer.  The Alessandro MS-1i's, however, sounded so good from the box that I really haven't noticed or cared about any burn-in on them.  That's my story and I'm sticking to it.

Here's a somewhat strange question...not even sure if this is possible.  After a solid period of use/burn in, can a high impedance headphone actually become easier to drive? 

 

I ask because I now have about 400 hours on my PK1's and I truly think that I can listen to them at a lower volume setting.  I was using my S639 with the Fiio E5 amp.  The E5 is cranked and my Walkman was at 13 on the volume.  But the last 50 hours or so, I have been listening to them on my Walkman at 10 or 11 on the volume. 

 

I really think I'm getting the same db out of them.  Perhaps I am just hearing a little better the past couple of weeks?  Not sure.

 

Does anyone know if it's possible for this to happen, or is my head just playing tricks on me?

I don't know that answer but I will pay attention when I use them next and see if it seems I don't crank my iPhone up as much.  Just started breaking my back-up PK2's in last night.  Didn't want to turn Radiohead's "In Rainbows" off.

Woot, my PK2's live again! All they needed was a plug replacement - had a local DIYer put in a more robust plug.

(part 2)

 

pk1 lovers i got news for y'all

 

 

i was in the Hong Kong hifi show and surprise one, Yuin was in the show!!! and surprise two, the guy there told me they're going to make a new pk1, or same driver new cable pk1.  i heard 5 sample there.  they're not finalize product.  just collecting information.  too bad i only have pk2 haven't listened to them for a long time and it was a very noisy enviroment but my impression was.... they need some burn-in.  3 out of the 5, the treble was harsh and the bass was really loose.  the other 2, better treble and bass but still, i think the need some burn-in

Hi,

 

As a fan of the Yuins I bought the Pk3 and PK2 as I wanted something on the go and at work. I love the sound of these both and this sparked my interest in the PK1 and OK2 which I have since bought.

 

On first listen the Pk1 sounded dull through my 1st gen shuffle but after around 20 hours they have started to break in and now I am totally in awe with these beautiful sounding musical messengers. People say they need an amp to sound their best and maybe so but they do sound better than the OK2 and other PK's without an amp out of my 1st Gen Shuffle! They may not go as loud as the others but do sound better at any level. One of the awesome stengths of the PK1 is their ability to sound beautiful at low volume levels, better than any headphone I ever heard, low or high volume and thats at aac256! Better than HD 650 with cd and mf xcan8 and all kinds of Grado's.

 

The bass on the PK1 is awesome and they go low and deep, even get some slight lung rattle going on there. The bass is not just boom boom but is fast, tight, multi layered and starts and stops very fast. The bass does not interfere with the rest of the audio spectrum. The midrange is sublime and the highs are wonderful.

 

Musical notes have their own time and space and just seem to float in the air around you. Soundstage is wide and deep, so deep that it seems like it comes from a blackness and quiteness from the depths of hades itself but with the voice of angels singing from heaven!

 

When I listen to the PK1's I never seem to want to skip tracks anymore. I'm used to skiping tracks a bit with other headphones/earphones and I find myself reaching for the skip button with the PK1 but then going wow I'm going to listen to the rest of this! The PK1's are very very addictive!

 

They fit beautifully, are light and look unassuming which is great as you can wear them for hours with the biggest smile on your face plus with a feeling of contentment. They produce sound in such a relaxing way that is also powerful and always musical, all kinds of music sounds wonderful! They can hang on to a note forever!

 

The PK1 can and do make life better. After a bad day I just put them in and my troubles melt away and they sooth my soul. They relax me in such a way (just like a good massage) that I forget my troubles and make my soul content!

 

Made in China and proud of it! My hat off to you Yuin and thank you very much. Yuin,,, heavenly sounds, you bet!

Suzuki, I am in at just over an hour into my new PK1s and I have to say I am identifying with your post.  I am very pleased at how effortless these things are to listen to an mine are not burned in yet.

post #927 of 1003

FWIW:

 

I've beat the crap out of my PK2's. 

 

For the last two years I've worn them  bicycling, at about 3,000 miles a year.  Needless, to say, the sweat is heavy.  This fall I painted my house while using the PK2's.  They got yanked on, sweated on, painted.  Still held up like new.  While the cable near the bud has stiffened, there's no other sign of any changes.

 

After I bought my first pair, I purchased a second pair because I thought:  these are never gonna hold up, better have a backup.  The backup is still in the can.

post #928 of 1003

Oh god, I thought that my next audio-related purchase was going to be an IEM... but after reading this thread I think that it will definitely be an earbud!

post #929 of 1003

I think I'm gonna drop the bomb on a PK2 - Not due to the PK1 being more expensive but because I want to use these straight out of my nano, not amped all the time - How do the PK2's compare to the Kossporta pros? redface.gif

post #930 of 1003

Good thinking.  The PK1 would take your nano full volume most of the time.  Just be a big waste of a good earbud.

The PK2 has excellent soundstage for an earbud.  I still find it pretty shocking sometimes.  It's not a good comparison to the PortaPro however, because of the lack of bass.  My personal opinion is that the bass is the PK2's weakest point.  I LOVE the bass so it took me a very long time to appreciate the PK2, but I listen to them almost everyday.
