Hy..
Just went to a B&O store in Shanghai, and auditioned the H3 and H6 , and i left with the H3.
I spent all all last night comparing them to the Future Sonics Atrio M5 and the Klipsch Image X10i.Being a dynamic driver, you would maybe start to compare them with the Atrio M5 , but there is no comparison here..even if the sub-bass on the Atrio is very hard to surpass, the overall presentation of the lower end freq are more enjoyable on the H3.What strikes you from the beginning with the H3 , is the sense of space that you get.All the instruments are no longer stuck inside your head.You get the feeling that some sounds come from outside the headphones.they do leak some sound outside because of the holes on the back,but is not very disturbing.Except for the lower end freq, H3 are in another class from the M5,so i let this comparison go, and switch to the X10i.
These are different technologies,but are surprisingly similar in sound.Bass is stronger, more punchy and better defined on the H3.When it comes to vocals, i think that on the X10i , they are somehow more refined..more sintetized...On the H3 , you feel every gasp,and harshness in the voices of Diana Kraal or Adele or Joe Cocker.To my ear it seems to be more natural,and i enjoyed it more...When i bought these , i was set up to find a phone that can be more enjoyable for classical music. there is nothing wrong with the X10i's , and while they are great for blowing instruments( trumpets,sax..) for violins and cello they are a little recessed.I wanted to feel and hear the vibration and the friction of the bow against the chords.(i found the beyerdynamic dtx80 to do this very well) , and the H3 delivers all this pretty great.Just try listening to some violin concertos by Jascha Heifetz ( tchaikovsky, brahms, mendelssohn) . Who is familiar with Heifetz , knows that he has a particular sound and a particular setup for his violin and for his recordings.It's not as easy sounding as Julia Fischer, Nigel Kenedy or Hillary Hahn. Only Itzhak Perlman comes somewhere close,but still different. So..back to the H3...The great part when listening classical music is the symphonies. It goes far away from the X10i in term of space and you start to feel enveloped in sound.Like i said before, the instrument are no longer inside you head...they are all around you.I even tried to listen a DTS video of Beethoven 6'TH symphony conducted by Karajan , and there a big difference between stereo and DTS track( on a Yamaha AV receiver)...It just opens up and you get surrounded by instruments, but at the cost of some clarity and refinement.
On the high end freq, i think that the X10i are doing a slightly better job, and the H3 suffers from a little harshness. Not much, not like the M5 , you just find some hisses a little piercing sometimes, but overall very enjoyable.I switched the silicon buds with the X10i, and because the canal is smaller in diameter from the H3 buds, it cuts the high freq, but a little too much.I found it to be better balanced with the stock buds.Also, while X10i suffer from horrid microphonics from the cable,on the H3 is barely noticeable.
So..overall, i found the H3 to deliver a better sound and it benefits from a much wider soundstage compared to the X10i.Seeing that the X10i are more expensive ( at least in China) than the H3, i highly recommend them.To be noted that i used different sources to audition them( iphone 4 , iphone 4s , ipad mini , Yamaha AV receiver).Apple changed the manufacturer of the audio chip between the Iphone 4s , and iphone 5/ipad mini.Like many others, i find the Iphone 4s delivers the best sound in all the apple products( also better than Samsung GS 2,3 ) with better soundstage and more power than any other.Even if some say that Iphone 4s is abble to handle over ear headphones, which may be true, i tried the B&O H6 , and i was dissapointed.I think they really need an amp to power these..They are supremely confortable ,design is great and have better seal than Sennheiser HD650 , or Mommentum, but really underpowered from an iphone 4s.
Final words : Put the H3's on and start AC/DC - You Shook Me All Night Long...(lossless preferably) or Michael Jackson - The Way You Make Me Feel...it will be hard to ignore these phones...
