Multi-IEM Review - 352 IEMs compared (Pump Audio Earphones added 04/03/16 p. 1106) - Page 39

post #571 of 16802

I started using a pair of Monster white hybrids (small, the only size that fits me) with the RE-Zeros, and I like them the best. Seem to give the bass a little more oomph. But I may try the filter removal mod too, since there are replacements should I not like  it.

I was told that a compromise on the foam mod was to remove the foam then put it back in so as to allow the driver to pump more air >> better bass response. Right now I'm finding plenty of bass kick but not much thump or extended bass. I also think that I'm going to have to invest in a cheap portable amp anyway (I got the Zero rather than the 0 so I wouldn't have to), because the iPod just doesn't quite have the juice for these. They shine at about 97% volume, and below that they tend to be a little tinny or weak.
Having to go full volume on some songs with IEMs means either they're not getting the power or I'm going deaf. I think FiiO will be getting some of my money by the end of this...

Oh, and the highs and mids are heavenly. No problems there. Any harshness or sibilance has almost completely ironed out with ~15 hours.

The thin bass notes are inherent with the RE0 and RE-ZERO, less bad with the ZERO.  It's a side effect of the design really.  You can EQ up the low end and add an amp, but there is only so much you can gain.  In the end, the lower frequencies will always be short on body and lack that heft and fullness.  That's why I mentioned earlier about loving to see a 2-way dynamic with the ZERO driver as the mid-high driver.

 

You don't understand the concept of the foam at all.  Foam is used to trap and destroy high frequencies.  It is used as an EQing tool to shape the overall response.  Air passes freely through the foam, but the shorter high frequency sound waves get trapped and blocked more readily than lower frequencies that would need much, much thicker foam.  Air isn't stuck in the earphone at all.  The foam is just a physical EQing device.

I didn't claim to understand the foam, I just heard that it was a possibility that someone had tried. The foam is positioned quite close to the driver, so pulling it slightly away provided more air directly next to the driver, which would give it more space in which to build bass whilst still having the foam filtering the highs (or something). I don't know if it works at all, but I was interested. Since I'm very happy with them I probably won't be doing any mods, but I thought it was worth asking to see what results people had found. I knew perfectly well that the RE-0/Zero were not strong in the bass department, but I settled on them anyway after a month or so's research to find the best IEMs in my price range. I know that they don't exactly 'need' amping, but the volume I'm getting from my iPod is pathetic and I was planning to get a LOD+amp at some point anyway.

 

Here's the foam mod explanation, from the IEM comparison table thread:

It also had a weak, somewhat sloppy bass, even with the stock dual flanges and UE tips. After some simple modding and lots of burin in however, I was able to eliminate these issues. To improve bass response, I took out the yellow foam inside the nozzle and put it back in such a way so that there is some space left between the foam and the driver. This allows the driver to pump more air and noticeably tightens the bass. I also squeezed the foam into the nozzle a little harder which helped to smooth out the treble (burn in took care of any peaks still present after the mod). Now my RE0 sounds very neutral with accurate, tight bass.

I didn't like removing the foam from the RE0 either.

 

JoeTheArachnid, the RE252 is better in balance than the RE0 if you don't mind spending double the cost.  This is part of the preference I have with the RE252 over the RE0 and ZERO.  There's more of a natural sense to the note.  Even that is slightly light in body on the low end, but the presence is more even throughout.  I'm highly curious about what the RE262 will offer over the current RE252.  I do like the differences that the RE-ZERO offers over the RE0, although the presentation is different.  There may be a slight presence towards one or the other depending on what you're shooting for in terms of sound.  I'm of the feeling that the RE-ZERO offers an even better overall package though.  At the end of the day, I'd still opt for the RE252 and pay the extra cost.

Well I've already got the Zero and I'll probably stick with it for a while. I actually couldn't listen to music on the go for a while because the PX100 are too open for my school bus environment and my awful cheap Sennheiser buds (Eco-Canal or something) just didn't cut the mustard. As a quick and cheap fix I'm absolutely fine with these, and I'll only upgrade if I get some more money from somewhere or if the RE-262 turns out to be the best thing ever... whilst still being relatively affordable. Maybe it'll be that dual-driver you wanted.

All I'm doing is just reassuring myself that there aren't any small fixes I can do to improve the sound, other than that I'll be content for a while... until the inevitable upgraditis kicks in. I see an MS-1, an M-Stage and an HD600/50 on the horizon...

Sheer awesomeness!  Thanks for such huge comparison!

Thanks for such an informative guide, it helped me narrow down my choices quite a bit. This post is being used to meet the one-post requirement to PM somebody about buying a pair of Monster Turbine Pro's.

Glad the thread was useful 

post #581 of 16802

Wow, you've almost hit 100. Now that is impressive!

Also, just so you are aware there are some coding issues at the moment. Half of the text is bold...

Annnd you can't read the last chart. I think you'll have to either split it into two images or not host it on head-fi.

Yeah I submitted an error report regarding code parsing. Nothing I can do about that - head-fi seems to be reading the number four as some sort of image or smiley which really screws up formatting.

 

As for the image, if you click on it and then right click and select 'view image' it will show up full size. But I plan to split it in two once I hit 100.

post #583 of 16802

Yeah, it now takes a couple steps to view the chart in its full size.

 

So what kind of cookies are you winning when you hit 100?

post #584 of 16802

Someone should start a fundraiser and buy Mike some decent customs or something ;)

post #585 of 16802

Well if he sold all of those under $75 earphones he would probably have a good amount :P
