FCS11D 11mm Dynamic Driver In-Ear Monitor $129
The FCS11 dynamic driver is a moving coil speaker that moves air. You’ll get bone induction and will feel the sound – not just hear it. The result is a larger more visceral high-definition audio signature at less volume. With two, three-way armature drivers, you’ll find yourself turning up throughout your performance as your ears fatigue. Not the case with the FCS 11mm dynamic. Another benefit over the multi-driver armatures is there are no electronic or comb filtering artifacts, no phase issues, and no crossover dropouts. The result is a consistent, huge musical soundstage from 20Hz to 20kHz.
The FCS11 sounds as good or better than earphones costing hundreds more. It’s the best bang for the buck on the market today. It comes with a 14-day money back guarantee. If you don’t feel it’s the best money you’ve ever spent towards improving your performance, you pay shipping back for a full refund. The product comes with a rock solid one-year warranty.
I haven’t spent the additional money on a retail package because the sale is direct to the performer. The earphones, cable, tips and cases come from different sources (best I could find to make the package). You’ll receive earphones, earphone case and a good number of tips to make sure you can get the correct seal/seating.

Couple thousand of you guys/gals have used our FCS210 and the FCS110. I began exploring options to see if I could build a better mouse trap.
I found an earphone manufacturer that had the patience to put up with all my tweaks. The finished version was the 19th sample and it was correct. I wanted to use a larger dynamic like in my days as National Sales Manager for Aurisonics. Other earphone guys use a 9.2mm (Fender) or a 10mm (Future Sonics). I think Shure’s SE215 is 8mm or less. I wanted my Marshall to go to 11mm!
The driver generates a massive production inside your head. The low end is thunderous, tight, punchy, concussive and huge. The higher registers are warm and smooth (not brittle and glassy like an armature IEM). The FCS11 also has a slight introduction of ambient sound.
The FCS11 is designed for the stage (can get louder). The Westone’s and Shure products are (I’m guessing) around 40% audiophiles and MP3 listeners. I maintain that a loud ass stage has some different needs than a subway seat or a workout at the gym.
When version 19 arrived, I put on the wave file I use to check earphone range. I actually started laughing. Here’s an analogy on the 11mm. You all have a couple venues in town that bring in Warrant, Brett Michaels, Skid Row etc. Then you have venues that bring in Elton John, Eric Clapton, Cher etc. It’s that kind of step-up. The 11mm sounds huge.
What were all the “tweaks?” Initially I had a 10mm which sounded good, but we already had good with the FCS210 & 110. I needed more if we were going to add another product to our mix. I had them find an 11mm. Went through 4 different drivers before landing on the biggest sound. The following tweaks were the EQ-ing of the IEM. This is accomplished with porting size and a scrim that can filter out specific freqs. That’s what really took the time. There were a lot of near perfect samples but #19 was outstanding.
All the Freq City IEMs in the past had several color options. The best sellers were the blue and the black. I limited to those two colors on the FCS11. Should we call them Cobalt and Onyx to be a tad more cool? I extended the stem gust a bit for better seating of the tips and added a flange at the stem to better hold the tips.
There are two versions of the FCS11 available. The FCS11D which has all the attributes I spoke of above. The FCS11B is the heavier bass version for bass players and drummers. I achieved the additional bass with a slightly larger port. All the components are the same.
CLIENT EMAILS ON THE FCS11 AND THE FCS11B BASS VERSION
Man alive. There's a percussion shaker or something on the left channel of my sample track. I feel like I can hear each grain in that thing. The cymbal splash is present and delicate. The bass is full and rich. I FEEL it but it's not boomy and doesn't overwhelm the mid-range at all. And the mid-range feels roomy, full, and spacious. Tons of power with crystal-clear detail, that's what I'd say about these. Really, really, nice. Dan Ray
Mike, I received my new FCS11 earphones this week and I was amazed by the big sound. I own SE535, SE425 and FCS210 earphones and the FCS11 blows them all away. These are clean and clear. They fit comfortably and have a good seal with the nice assortment of tips that you included. They are affordable enough for the entry level performer but have the quality needed for a pro player. I'll be telling all my fellow musicians about them. Ron Combs
I haven't played out yet since I got them, but the bass response is huge and detailed for monitoring in Ableton and Logic Pro. Not ashamed to say that I’ve done quick mix downs with these, since they are always at hand. As I write this, I have them plugged into my MacBook Pro and I'm jamming out to some high-fidelity recordings. Did I say HUGE? Thanks Mike, quick response, and a great value proposition.

I just received the In FCS11B. Tried them out and am blown away! These are amazing! Thank You! Jim
I got the bass in black and they are wonderful! Used them in praise band at church last weekend and the first time I put them on, I thought I had my bass amp turned up too loud. No, it was the enhanced bass from the FCS11's but I could hear voices and other instruments clearly as well. Amazing sound for the cost. I would put them up against my Shures which cost probably three times as much and these give me more bass response. I like them so much that I am ordering a pair of regular in the black as a backup for my wife who does vocals. James Crider
Circling back around to you on the FCS11. I really like them, and prefer them over the 210's. They shine on stage! They are a much better and fuller sound! I am so glad I made the purchase. I ended up giving my wife my 210's, being she is singing now, and quite appreciates them.
Thank you so much for your commitment to excellence, developing better products, and offering at affordable price points!
Have a great week! Mike Wiley
“As a professional musician, (Percussion, Keys, Drums, Studio) I’ve found the FCS11B IEM’s to be a very powerful tool for live and studio applications. Snug fit for good isolation, long cord for tangle free movement and a great sonic balance. Well-built and nicely packaged. They are a great value!” ~ Frank McGucken (Madrigal Percussionist)
“I love the sound of my FCS11 IEM’s! They have great low-end response, and they fit my ears perfectly. I use them both on and off stage.” - Josh Weinstein (Kat Wright, Burlington VT)
I play Bass in a band called Cheat ’n on Tucker and we recently made the switch to IEMs. However, none of the brands that I tried at first gave me that low end sound that I needed to perform my best. After going through 4 or 5 different brands, I finally found the FCS 11 by Freq City Sound. Game. Changer. They are the bomb! The FCS 11’s have the perfect sound necessary for Drummers and Bass players to stay tight when they need it most. If you’re looking for the low-end answer to the IEM question, these bad boys are it. 10/10.

I'm using the 11B's and love them! Great fit with the wide selection of tips included.
Richer, more clear bass than my Shure SE's in custom molds, and I'm finding I can now run at a more comfortable volume level and have zero ear fatigue after use. "Exactly as described in description" is cliché but spot on for the FCS11B's!

"Several years ago, I bought the FCS210's and have loved them. Received the FCS11's for Christmas and put the 210’s away as spares. The additional driver size work great for me and easily rival name brands priced 2-3 times more." Dr. Nick Swink, church & freelance bassist Tipp City Ohio
the FCS-11 In-Ear Monitors arrived today. Wow! these are the best sounding iems I have heard by far. I am glad I did not go for the bass enhanced FCS11Bass, as these are perfect. The bass is massive but not boomy. The mids and highs are perfect and overall, they take eq well. If I want a different sound signature. One other great thing I have noticed is that the sound does not change when I move my head or open my mouth, both things that other iems I have tried are very prone to do. The FCS-11 is very consistent. They also don't irritate my tinnitus, which is a blessing.
Most of the tips you sent sound great, I've settled so far on the double flange that were on the phones when I received them.
Thanks, I will be recommending these to my musician friends. Cheers,
