Hi there. Long time poster here but haven't been online for quite some time and forgot the password for the other account. Also I've been away from listening to audiophile gear, and the last IEM I had was a Monoprice which is the king of budget IEMs or so people say. If you haven't heard it, try one now, for under RM100 hardly anything can beat it.

The ATH IM50 is my first Audio Technica product, and I chose it to mark my re-entry into portable audiophile.
Anyway as usual when it comes to reviews, some basic specs:

Driver: 2x 8.8mm dynamic "Dual Symphonic" drivers
Impedance: 10 Ohm
Cable length: 1.2m, removable
Colour: Black or White (mine's white)
Accessories: Carry pouch, S/M/L silicone eartips
Build: Plastic

As you can see it has the bare essentials, nothing fancy, but the IEM is well packaged. The build quality is fantastic. Though plastic and feels a bit like a toy, there is nothing loose anywhere. No silly gaps, no creaking, nothing loose not even the connector for the removable cable. It's sole purpose is to allow removal only when the time comes for necessary replacement. I tried to take it of but it was too tight so I just left it in fear of breaking it. I couldn't grip the IEM and jack tight enough, but if I could grab the cable end a bit, probably, but only when the cable starts to deteriorate and it's time to replace them anyway would I do it. Others have tried from what I've read and they all report tight cable, so it's not a fault. The bit connecting to the IEM is made up of memory cable, that stiff bit that you can mould to the shape of your ear. At first I find it awkward but as soon as I got it over and around my ear, putting on and taking of after that is a breeze. Again, this IEM is SOLID.

As the lowest and cheapest in Audio Technica's new line of IEMs, I held some reservations into how it would sound. With that I was caught off guard.

Some interesting fact about the "Dual Symphonic" arrangement, it's two dynamics (presumably one is tuned to favour a certain freq. range) working synchronously (no crossover) and one is placed in front of the other. Logic says it's the wrong thing to do, but somehow they pulled it off. First thing I notice is that it sounds quite full, yet spacious. It doesn't dig deep at the bass, but it made sure to present whatever it has as best as it can. There is some rumble if you give it the right music, not the fastest but good nonetheless, almost behaves like it would from a monitor...unless if you crank up the volume, then things can start to sound overwhelming. Mids is nicely bodied. I never felt that voices were too thin or a bit too forward, and high mids are not fatiguing.

Treble is where things aren't so interesting. It's not very...realistic? My favourite IEM for treble is believe it or not, the Monoprice 9927, the one I had a short time ago before I sold it to my friend for RM10. tongue.gif Cymbals sound oh so real! And not to mention guitar strums and cellos. Treble with the IM50 is in no way crude, at most I would say pleasant, at the very least I would say it's listenable. It is not piercing so that's good. This IEM is still very new but I am hard pressed to find significant changes over the 20+ hours I've listened to it. I can live with the treble because the rest of the spectrum more than compensates.

I like how the IM50 is able to dissect the music to some degree yet still be fun to listen to. I think it's the whole point of the IEM, it's freaking fun to listen to. The rumble of the bass intro in Muse's Hysteria, full-bodied cellos from Apocalyptica's Fisheye, and lush vocals of Norah Jones.

It's not the best IEM, but for its price I can't think of another. I will soon be comparing this to a Shure SE215-SPE. I don't know what to expect, I don't know how close. I don't know if I'll sell one in favour of the other or to keep both. Hopefully next week I will have my answers.

Great analysis!

IINM, there are lots of examples of dual dynamic drivers placed parallel to each other without the use of crossovers. IIRC Radius DDM is one example. Then we have the KEF M200 right? JVC FXT90
drivers are side by side.

Anyway, IIRC both Radius and KEF don't have sharp treble. The bass is plenty but doesn't dig deeper. It's very full bodied. And the staging is quite huge.

Anyway, is there a higher model for AT dual D driver right? Looking forward~

There is, the IM70. Said to have slightly boosted bass and overall more presence and power. There is also some metal in the bodywork of the IEM for the IM70.

I had the Radius DDM1 a few years ago, and yeah the treble was lacking, to the point where electric guitars sound dull. But everything else is wonderful, and the mids on that is definitely better, and the transition from mids to bass is excellent. This (IM50) isn't so recessed, but it struggles with getting it across. It's letting you know it's there, but not really doing everything it can at extracting details out in that sound region.

The dual symphonic drivers are quite different than ones in FXT90 or Radius. The Radius has the larger driver and smaller driver facing different direction and share the same magnet. The FXT90 has two tiny independent drivers but one is on top of the other. The IM50 has two independent drivers (from the looks of the diagram anyway) and they are placed in-line; one in front of the other facing the same direction. Probably the rear driver has a channel to deflect and direct sound around the front driver, I don't know.

But it somehow works. tongue.gif

DDM has the same magnet? Didn't realize that. FXT90 has two drivers of slightly different materials but positioned next to each other. KEF M200 too, is unique.

You heard about the Ocharaku Flat-4 series? That's one heck of a job too!

Even the aurisonic asg-2 was meant to be dual dynamic LOL.

Anyway, tried amping it? Any difference?

Yeah heard about the Ocharaku, but never really had laid my eyes upon it in real life. It has a novel configuration, one driver producing the actual sound, while the other serves to cancel out any resonance/interferences/noises IINM.

I've sold pretty much all my music players, amps and IEMs and I'm trying to get back into this hobby, so no I haven't tried amping it. With its low impedance I doubt that I need to add an amp. It's doing fine at around 20% volume of anything I plug it into.

BTW, the Aurosonics is such a beauty! drool.gif

How much for the IM50? In Amazon it costs somewhere around USD69, so that's about RM220 or so right?

I bought it from E1-AKG. Including shipping cost it could be just a bi more but still be much less than RM300. More if you'd buy from a seller who doesn't have ready stock. Since he supplies from Singapore, I guess it's possible to get at lower price.

I have no idea. However they are both in different price regions and have different sound signatures, I don't think a comparison is fair nor does it warrant any. They are both made for different goals. The 232 is likely far more detailed and faster.

I would love to own the JVC HA-FXZ1000, just because of the novelty value. tongue.gif

I'm sure it'll sound more than decent, but there's something about "triple dynamic" that can wow the general public when I mention it. laugh.gif

For those finding the highs a little lacking and bass a little bloated on both the IM50 & IM70, here is your solution tongue.gif
