Generic IEMs? Custom IEMs?

We discuss various IEM molds here and I'd like to clarify my stance, for what it's worth on custom molds vs generic molds.

First and formost, I will always recommend going the expense of getting custom IEM molds made. I've had a set of 1964 Quads for over 2 years and I experience the same fit each and every time I use them. I don't have to worry about losing generic inserts or changing them when they get grody (deep Southern word for "nasty"). Now, 1964 Ears, or 64Audio, I think they are called now, makes a set of the A series custom IEMs for $399. One of our church drummers just ordered a set (Young college student, incredible drummer, even bigger heart for the ministry and counseling kids, doesn't make a lot of money) and we'll know in a little while how they work.

However, discussions and questions come up here about generic molds and while I seriously adhere to the belief above, I do know that with some diligence and work, a decent fit and seal can be had with the generic molds. Once, I broke the cable (snagged it on a door handle, lucky it didn't damage the IEM mold) and had to wait on another one from 1964. While I waited, I borrowed a set of Westone UM Pro 30s (triple-driver) to get through the weekend at church. I gotta say, I was rather impressed. They were PLENTY loud, and while not as low-end-tilted as the Quads, I was able to get happy with them rather easily. I used the yellow foam inserts rather than the gray, various-sized inserts. So I bought a set of UM Pro 30s as a back up. Plus at times, they serve to be a user's first IEM experience. They aren't cheap, around $350 these days, I think. But I do highly recommend, bassists and drummers should go no less than triple-drivers to be happy

A friend of mine bought the UM Pro 40s, I think they were 0ver $500. I asked him why not just go custom? He doesn't fancy the idea of custom-made molds. Fair enough. Who am I to discourage him?

So, to wrap up....

If you simply don't want to go with a custom mold solution, there are options out there that can be satisfying...I guess...:D. Seriously, I could live with the UM30s and wouldn't mind terribly doing so. But I'm very glad to have my 1964 Quads and can't imagine having to go with less.

Part of me wanting to write this is to caution users against the lesser-known and less-expensive IEMs. This year, more than ever, I've seen folks go with something like the SE215s as their first IEM experience and come away hating the experience.

However, to wrap up and to head off some grief from those folks...

If you are happy with an inexpensive set of generic IEMs like the Shure SE-215s, by all means,
carry on. You don't need my approval or otherwise. I've made up my mind and it won't be changed. I expect no less from everyone else....:thumbsup:

I'm with @Geri O -- Get either.. but get the BEST you can afford.
I have smallish canals and have NEVER been able to get universals to stay put.. going custom was a no-brainer once I had the moolah!
Will never go back..

I've said this many times.. I've never understood musicians who literally spend MANY thousands of dollars on their gear, buy digital mixers and high-end PA speakers to make the band sound great.. yet want to put $50 buds in their ears and have them sound awesome.

DON'T CHEAP OUT ON BUDS...you'll blame the system for you poor decision.
That's my $0.02 advice. .be that universals or customs.
 
For those on a budget given the choice.....would you recommend custom with less drivers, or more drivers but generic....I.e. 2-3 driver customs, or 5-6 driver universals??
I'm far from an expert in the area, but I'd have to respond with a BIG "it depends"...

The main issue with universals is one's ear/canal size. Many don't get a good seal with the stock tips, leaking HF and LF. They often go with 3rd Party "tips" to try to alleviate the problem. They also work fine for many and are MUCH cheaper than their custom equivalents.
Being that custom molds are built (molded) for YOUR ears specifically, the seal SHOULD always be better than with comparable universals... but again.. that's based on YOUR EARS!

But it does beg the question as to how many drivers do you REALLY NEED in each?
I recommend at least 3.
Why three?? Three will give you the frequency split, associated clarity and soundstage that comes from having a 3-way xover and 3 BA's in each ear that run high, mid and low frequencies. Think of it like having a miniature 3-way PA speaker in your ear. A 3-way speaker is generally better than 2-way with both ALWAYS being better than ONE speaker trying to reproduce the entire audio spectrum.
I think one can now go as high as 16 drivers in high end customs, but there's not much data out there that categorically denotes them as being better than 12 or 8 or 6 or 3 drivers in each ear? YOU have to decide.

I have used single and dual-driver universals (due to budget constraints), and 4 and 8 driver customs. I don't really hear much difference between the 4 and 8's, but the 8's have the 1964 ADEL technology to equalize pressure inside the ear canal, meaning they are not fully sealed like the 4's. Audio quality is stellar in both.. but I hear bass artifacts in the 8's that I can't with the 4's. I believe that's due to the 2 extra LF BA drivers in the 8's.

So, if universals work for you.. yes, 3+ drivers will "probably" sound better than dual customs. I honestly can't tell you if 4 or 5 driver universals "will" sound better than the custom equivalents. It depends on your ears, but I'd guess they do not.

In conclusion, I'll repeat what I said above.. whichever route you take, get the BEST you can afford.

Me, personally, I'd go for a custom mold 3-driver IEM. The seal is the imperative part of IEM monitoring.

The 64audio A2s....A2s...A2s... are custom-molds, but only 2-driver units. This concerns me a little, but I'll know more when a drummer buddy of mine gets his in. I wish I could comment further on these.

Having said all of this, my favorite universal, or generic molds are 3-driver units, the Westone UM30s. Read my first post above with my thoughts on this.

And for anyone that mentions being on a budget, I certainly understand, but I saved for 2 months before I spent nearly $600 on my custom-mold Quads. So consider holding off on your purchase and saving up for better IEMs.

Geri.. the A4's have FOUR drivers per ear ... not 2.
They are the ADEL version of the Qi's we both have..
 
We used the Shure SE215 ear buds ($99) in our band for roughly 170-180 gigs a year and had no issues and the noise cancelling was plenty good enough. I always felt the bass tone I had was great. I know they are definitley better alternatives out there for more money but the bang for the buck can't be beat with these IMO.

SUB'D...

I personally can't stand the universal ear bud type... they never stay in my ears the right way.
So I researched and realized I couldn't afford customs, until my drummer told me about a small place in Tennessee called Eartech Music .
Checked their site, great options and pricing .
Originally was going to go with triple driver monitors , but decided to spend just a bit more on quads...
They fit and feel great, work perfectly , and sound amazing !
I'd encourage anyone looking for IEM's for the first time to check out Eartech , they were very friendly and patient with all of my newb questions .

Yes, I usually bring my own but have been using the generic Shure IEMs for a few TV appearances (where the producing company provided all gear). No problems whatsoever. I guess my ear canals are generic enough...
 
It's definitely personal preference.. but.. there REALLY is a huge difference between listening to the SAME stereo (or mono) mix with multi-driver customs vs SE215's (single drivers).
I have used both...
 
I've used Shure 215, 315, 415, 1964 Quads, 1964 A6s, and 1964 A12s.

  • Can you get by with generic Shure 215s? Yes you absolutely can.
  • Are the higher range model 315s and 415s better? Yes they are.
  • Did the 1964 custom molded Quads feel and sound better than the generic buds? Yes they did. Was the difference night and day? No. Was it an appreciable difference? Yes.
  • Are the A12s (12 drivers) superior to the Quads (4 drivers) and the A6s (6 drivers)? Yes. Is it an appreciable difference? Yes. Is it a night and day difference? No.
The law of diminishing returns is strong here. Spending a lot more money for better and better buds gives you smaller and smaller gains. But those gains are definitely there.

It all depends on how much you can afford and are willing to spend and how important those small gains in audio quality are to you.

I think that if I was playing 10 gigs a year I would find it hard to justify an expensive set of IEMs. Currently I am playing about 50 to 70 gigs a year so I feel that they are worth it. But I completely understand those who cannot justify it.
Also, my head and cabs ran me close to $2000 so, now that I am no longer using them, I figured that I could spend something similar on IEMs.

I gotta say, I'm doing that many gigs and I'm scratching my head over the need for A12s...:wideyed:

However, I'll certainly look at A6s or even A8s.

Right after I get that REDDI bought and paid for. And oh, yeah, a $1000 set of tires for my SUV...:D

Not to mention, after a little over 2 years, I'm still enjoying my Quads. I guess I'll have to experience the A series to really get it. Everyone I've talked to with them are very pleased, so there's no doubt about the improvement.
