PROS: Build quality, rich unboxing experience, good EA stock cable, nice carry case, comfortable fit, small shells, resolution, coherency, balance (with foam ear tips), reference-ish character.
CONS: Stock tips not the best pairing for sound signature, no lip for ear tips, signature needs refinement to work as true reference, uninspired stock shell design.
I would like to thank Empire Ears for sending me ESR to test and review. I am not affiliated with the company or any of its sellers and write this review with an unbiased opinion regardless of how the review turns out.
I majorly listen to rock, acoustic, pop, metal, and sometimes popular EDM songs doing the rounds on the charts.
About Empire Ears.
Empire Ears certainly don’t need any introduction. For those of you who have been living under a rock, Empire Ears are one of the most popular brands in the world, a family owned company based out of Atlanta (Georgia, USA). They have over 30 years of experience in acoustic engineering and manufacturing spanning the medical, consumer and professional markets. They have 2 different range of IEMs,
- X Series (Bravado, Vantage, Nemesis, Valkyrie and Legend X)
The Empire X Series is raw and instinctive, unwavering in its singular purpose: to overwhelm the auditory senses through the vigorous spirit and emotion of a live performance.
- EP Series (EVR, ESR and Phantom)
Engineered to obtain the highest standards of audio reproduction, the Empire Professional (EP) series was designed alongside numerous Grammy award-winning artists, musicians, producers, and engineers, to deliver music as it was intended to be heard. The EP Series features a myriad of new technologies including: synX crossover systems, anti-resonance compound (A.R.C.), proprietary balanced armature drivers, and bespoke, handcrafted Ares II cables by Effect Audio.
Their IEM Legend X in particular is not just one of their most successful products but is also one of the most popular IEMs in the audiophile circles.
According to Empire Ears, the Empire Studio Reference (ESR) was tuned specifically for discerning producers and engineers that require a non-coloured, linear in-ear monitor for reference use. The ESR features a powerful 4-way synX crossover network with 3 proprietary drivers to reproduce the sonic transparency and critical details needed for mixing and mastering. The ESR is Empire’s flattest in-ear monitor and it delivers uncompromising dynamics, ultra-fast transient response, and wide dispersion for use in studios and on stage. Every aspect of the ESR was conceived, designed, and crafted to faithfully reproduce what the artist had intended.

ESR has a lot of Empire Ears proprietary tech inside like SnyX Crossover network and A.R.C., so if you’re interested in knowing more about it, Empire Ears have explained it pretty well on their ESR product page (link).
Included in the box.
Empire Ears IEMs have a rich and luxurious unboxing experience. ESR’s box has two levels, with IEM, cable and manuals on top and case, ear tips and cleaning brush at the bottom level. The bottom level slides out nicely and everything is easily accessible. 10 points to Gryffindor, ahem… Empire Ears for the nice packaging design.

Shells – ESR stock universal shells are black in colour and are made out of medical grade resin with EE logo on the faceplates. They are well made with nice smooth semi-custom contours. The 2-pin sockets are tight and they grab onto all 2-pin cables very nicely. They sit flush with the shell surface and aren’t the recessed type. The nozzles are small and fit most 4-4.5mm ear tips nicely. Sadly, they do not have a lip and the stock Final-E tips tend to slide off once the shells get greasy and I’ve had to fish them out a couple of times. So, a lip is always a good thing to have. In ESR’s case, what helps is that I anyway prefer foam ear tips for sound and they grab onto the nozzle tightly and never come off.
Cable – ESR comes with the famous Effect Audio Ares II UP-OCC Litz cable as stock. You have the option to choose your jack types and terminations while placing the order. Ares II is a very nice cable with a relatively tight braid which makes it tangle free. It is slightly microphonic for the same reason but you don’t hear it when listening to songs. All in all, this is one of the nicest cables that comes as stock with an IEM at this price point, so no complaints here.
Case – The case is made out of metal and is very well built. The paint, finishing as well as the etched logo all look very classy. It is small enough to easily fit in your bag’s front pocket yet spacious on the inside to easily fit the ESR with the cable.
Fit, Comfort and Noise Isolation
ESR with its semi-custom contours fit my ears snugly. I use them with nice squishy foam ear tips mostly and as a result comfort is excellent and they disappear in my ear once worn. Noise isolation is good and I cannot hear the air conditioner or fan running in my room with them in. You can comfortably use them for your commutes and noisy factories, and they’ll block out most of the background noise. Of course, going the CIEM route will be even better for the same.

Nice review. Agree with “warm, musical but not quite reference.” I found the spinfit CP240 worked well for me. I changed the Ares to a hybrid 8W which opened the soundstage and clarified the treble.
Hi!! I wish you are fine during this COVID situation!
I really love your web and read it periodically. I love music and I prefer iems rather than headphones because I wear glasses and also headphones make my ears extremely hot…
I have a modded Sony MH755 (lovely for the price, with mmcx cable), IMR Z1 zenith, 1more triples and some soundmagic.
I would like to improve and find my “endgame”, I love listening to music as recorded, neutral tunning, but fun, I love music and I listen to almost everything: classical, rock, hip-hop, OST, orchestral, electronic music…
I have read your ranking but, for an average worker with a mortgage and other hobbies… are extremely expensive. I live in Spain and I cannot test iems. Based on your experience, what would you suggest me, being iems with the best cost/performance ratio, and great sound?. I would like to spend once rather than having some mediocre iems and not be satisfied, my budget is about 500€ but I could spend up to 1000 if you consider that it is necessary. A friend has encouraged me to buy a Campfire Audio Andromeda and that that iems will satisfy me completely…Looking forward to hearing from your opinion, David.
Thanks in advance, David
Hey David! Thanks a lot! Tw6 team appreciates your love and support. Well IMO, you don’t have to spend the biggest bucks to find an IEM which plays your music well to keep you happy and satisfied for a long time. 🙂 In order for me to suggest some IEMs for you specifically, can you please tell me if you are sensitive to any specific frequencies and if you have a specific tuning in mind? Also, have you looked at some other options besides CA Andromeda?
Hi! Thanks in advance, many thanks, sincerely. In the IMR the treble make me fell upset, I have reviewed all your posts and also in HEAD FI but there are so many models that I don’t know…the Andromeda seems to be recommended by everyone. I would prefer a big soundstage and the other preferences I wrote before, neutral but fun if possible… thanks in advance, David
I have a couple of IEM suggestions. Please PM me on Head-fi since this will take some back and forth. Here is a link to my profile – https://www.head-fi.org/members/animagus.502720/
