Thats just like playing with fire, isnt it?

post #2102 of 2265

i think someone posted one some time ago

the 600 is more dark than the 272 , with more bass and body

at least this is what i remember from it

having both the 262/272 (and being very happy with both) i wonder how much an improvement the 600 would be

the re-400 was a dissapointment imo - both 262/272 rip  it apart easily.

Maybe they put that grain there on purpose to get people to buy the RE-600??

 

I'd happily pay a little more for the RE-400 if they worked on them just a bit more and removed the little niggles that everyone talks about.

I can confirm that mids sounded "grainy" to me on RE400.

We are answering to all reasonable letters. There is 6 different ways to contact on our site. So you probably made a mistake in your email address while filling contact form.

Many times. What info do you need?

Oh, very nice! I am wondering why the impedance difference on these two IEMs? Is there a resistor in the housing? What is the major differences between 400 and 600 internally? I just have a hard time believing they are different drivers (if so, voice coils differ perhaps?), and a couple mods may be possible to turn the 400 into 600.

 

That's my suspicions anyway :)

LOL...My RE262 was $149. They want me to send it back and pay $40 for RE400 which is only $100. 

 

They take back a problematic headphone, recondition it and sell it back on the market as refurb or warranty replacement. At the same time, it leads me to think that the cost of RE400 is probably less than $40 bucks, which they also profit on. Smart, but i need to look for another brand.

Well, you forgot to mention that your RE262 is out of warranty. So they basically offer you a $60 discount on a $100 phone as a gesture of goodwill.

It's pretty much reliant on voice coils - check out these two articles:

http://rinchoi.blogspot.com/2013/07/hifiman-re-600-part2-general-analysis.html

 

There is some technical info in there, but if you read the 'second thought' components it will shed some light on how they compare.  From my experience, the RE-600 is a bit darker overall with slightly more forward mids/sub-bass (and less forward treble) comparatively.  As a result they seems less airy but warmer and smoother and manage a larger soundstage (perceptively anyway).  The differences aren't as big as you'd expect though given the price difference, but if I were to pick one regardless of cost it would probably be the RE-600.  Their presentation is a little more in line with my preferred sound signature, the coated housing a bit nicer and the cable seems a bit more durable.  Still, I am satisfied with the RE-400, don't get me wrong :D I've got a thin circle of felt in each nozzle between the hifiman filter and the nozzle foam and I like the results.

Thanks for the info! I really prefer the RE600 over 400 myself too, it has such a natural non-fatiguing sound that i can enjoy for hours :) Which is really quite a remarkable feat without being too dark, or masking alot of detail.

No, there is no resistor inside the housing or cable.

Voice coils are different. So unfortunately there is no way to turn your 400 into 600.

Does the felt improve the sub-bass any? :smile: I'm guessing not, based on Rin's graphs.

 

The mod you've mentioned here is different from the one you've described in the tour thread right?(where the felt/foam was placed in the tip).

It actually does slightly because it pushes everything above 1k down the more acoustic damping materials you add, so the bass is technically brought forward a bit compared to the rest of the FR.  The felt was not quite as dramatic as the hankerchief/microfiber cloth which I also tried and makes it even darker as you can see in the charts.  The felt from the tour is the same as what I use, but I just put it in the nozzle to make it more permanent.  You can sample it by placing the foam/felt in the tip so I just included it for those interested in hearing the effects so they didn't have to take the HiFiMan filter off...shouldn't make any sonic difference if it's before or after the HiFiMan filter though.
