Some IEMs are more sensitive than the other. IM50 is easy to drive and sensitive, also has good frequency response, so it is normal if you hear more on IM50.

What @twister6 suggested is a good idea, to put some resistor to increase the output impedance, might reduce the hiss. Something you can DIY like what I did here:

At least till you have a better source / player.

So i have a bit of a dilemma i am looking to buy myself new iems and the two options ive narrowed it down too are the audio technica ATH-IM70s and the Fostex TE-05 both phones have appealing aspects to me but im just wondering if someone who has heard them both could do a comparison for me. Any and all input is much appreciated as this decision is starting to give me a headache xD

I've both IM70 and Fostex TE-05.

What I don't like from TE-05:

1. Treble peak that makes it prone to sibilant. While it is pretty good with classical, I would avoid it from pop vocal, especially with those vibrant treble recording.

2. Noise isolation is lesser than average. Somehow it doesn't isolate noise very well.

 

Both IM70 and TE-05 have different sound signature. IM70 tonal balance is smoother and more organic, almost free from any annoying frequency peaks and dips. But for classical, TE-05 is a bit more transparent.  So, back to your music.  For modern genres, I prefer IM70 by far.

Thanks for the input I also spent a good deal of yesterday reading posts on here and since modern music is more or less all I listen to I will be going with the ATH-IM70's as my decision

@earfonia, Do you still have IM50/70s with you? If you do have, could you please compare "unfiltered" IM50 to filtered IM70 as I'm still wondering if it is worth upgrading to IM70 without filters. Thank you.

Yes, i bought both. I like them :-)
You mean the filter on the nozzle right?
Will try later at home.

Yes, the nozzle filter. Did you try it?

Hi Ozkan, sorry for late reply, been busy these days.

 

I just did some comparison today, and I would say in for the level of clarity vs bass, top would be the highest clarity with lesser bass, down to the lowest clarity with more bass:

 

IM50 without nozzle filter (clearest, less bass)

IM70 with nozzle filter (balance)

IM50 with nozzle filter (less clarity, more bass)

 

Please note that the difference is small, not night and day kind of differences.

 

As for which one I like, with or without nozzle filter, I like the IM50 without the nozzle filter, nice clarity with still good level of bass, although slightly less bass than IM70, but also slighlty better clarity than IM70.

I don't think for those who already bought IM50, to buy again IM70.  The difference is small, and IMHO not worth the extra bucks. If you want more clarity, just remove the nozzle filter. Want more bass from filterless IM50, use smaller bore eartips.

I think I will keep my IM50 nozzle open, without the filter. I like it that way.

Hope it helps ;)

 

 

DIY switch box for comparing IEMs.

 

On the picture above, I was experimenting with smaller bore eartips from Earphones Plus:

That's why there is blue color on the eartips. I like that eartips with IM50, a hair more bass than the stock tips.

Once the filter is removed is there a way to place it back on the nozzle? I was thinking of replacing the filter material sometime lol.

The sticky part of the filter is still sticky after removal, so I think it can be put back to the nozzle. I keep the filter, pasted it to plastic sheet, to keep the stickiness.

 

That's would be an interesting experiment :D

 

Please post your findings here when you did it. Thanks!

Golden Ears measured the IM-04 and 02.  both have a 3k dip, and the 04 has sharp treble rise, I suspect it to sound bright and bassy with mids buried.  The 02 on the other hand doesn't have the treble peak with more linear treble response.  02 does look more linear overall.

stupid question but are these particularly hard to get in the US? I want to buy the Im03 domestically to warranty it with AT US but the options are almost all asia imports.

AT US keeps telling me "next month", reassuring some time in July. I will ping them again next week and post what I find out.

Very interesting measurement!
I've written in the review on page 1, IM02 perceived linear which is in line with Golden Ears measurement, but IM04 is warm with less treble and clarity compared to IM02. IM04 is more mid-centric in comparison. So IM04 measurement is different than what i perceived.
