Crafted from anodized aluminum with CNC machining, they offer durability and a slim profile. Featuring a single dynamic driver and a detachable cable, these earphones provide precise, neutral audio ideal for audiophiles, sound engineers, and music creators seeking uncompromised accuracy and customizable comfort. ## Description The flat frequency response of the ER2SE will appeal to sound professionals and audiophiles alike. The ER2SE shells are made of anodized aluminum, CNC machined with extremely tight tolerances. Using a single dynamic driver allows for a very accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim. Included is a user-replaceable cable. The ER2SE offers Etymotic’s renowned passive isolation, providing 35-42 dB attenuation. Both ER2 models, the ER2SE and ER2XR, use the same low-impedance dynamic drivers. The difference between the 2 models is the tuning of the lower (bass) frequencies. The “Studio Edition” ER2SE is tuned to have a flat frequency response. The “eXtended Response” ER2XR is tuned to have an emphasized bass, adding 1-2dB to the mid-bass and 3-4dB to the sub-bass. ER2SE is a great choice for audio creators and musicians on a budget, who require a precise and neutral sound reproduction. ER2SE is also the IEM of choice for consumers who prefer to listen to their music exactly the way it was recorded. Ideal for sound engineers audiophiles who are looking for in-ear monitors that are easy to drive while offering accurate audio reproduction. Accurate Earphone Reproduction When tuning in-ear monitors to accurately reproduce a recording of a live performance, our goal is for the sound hitting the eardrums to be identical to that at the original performance. To achieve this, the acoustic properties of the ear must be factored in. The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear. That is the reason for the “hump” in the frequency response graph, which assures the eardrums perceive a perfectly flat frequency response for all frequencies. Review: Great Sound, Solid Build - These earphones are well built and sound excellent. The bass is nice and punchy, the mids are clear, and the treble stays controlled and doesn’t distort at higher volumes. I also appreciate that Etymotic includes extras: a case, foam tips, large triple-flange tips, and extra double-flange tips in all sizes. Review: Great sound, great isolation. - I got this to cut down on the AC noise near one of my rooms. I expected decent sound and decent noise isolation. My expectations have been greatly exceeded. First the isolation: when no music is playing I can still hear the AC if I get close enough. Once something starts playing, nothing. The downside is that you won't hear it if someone's trying to talk to you, so one should be careful using it outdoors or anywhere situational awareness is required. The sound: absolutely outstanding. I really can't find any weaknesses. Everything is natural and balanced. The timbre of instruments and voices is natural and there's enough bass, as much as can be expected from IEMs which can't produce the visceral bass of speakers, anyway. The spatial qualities of the sound are as good as can be expected from IEMs but again don't compare to speakers of course. Other things such as detail, balance between treble and mids etc are outstanding. Comfort: for the first couple of days my ear canals got itchy after about an hour or so but now they've accommodated and I can wear them without any discomfort. They are pretty light and the included case is pretty small. Value: desertcart had them for 125 before the holidays and they are outstanding value for money. They seem to be well built and should last quite a while unless mistreated. ## Features - True high-accuracy sound experience - Metal earpieces with anodized finish - 35+ dB of external noise isolation - Assortment of ear tips for the perfect in-ear fit - Detachable cable allows for easy replacement ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NSQBK1X | | Additional Features | Lightweight | | Age Range Description | Adult | | Antenna Location | Recording | | Audio Driver Type | Dynamic Driver | | Best Sellers Rank | #106,336 in Electronics ( See Top 100 in Electronics ) #4,563 in Earbud & In-Ear Headphones | | Brand Name | Etymotic | | Built-In Media | In Ear Monitors, Detachable 4 ft. cable with 3.5mm gold plated stereo plug, Assortment of eartips: 4 Dual Flange Silicone Pairs: S, M, L, XL. 2 Triple Flange Pairs: Standard and Large. and 2 Foam Pairs: Standard.

It does have a tab to prevent them from spinning however, so I'm not sure if it would work with standard MMXC connectors. **Q: what kind of eartips can I purchase that would fit these?** A: If you have larger ear canals, as I do, the triple-flange ear tips (which offer the best sound isolation) provided by Etymotic are too small. Google search for "6pcs (M-LB) Triple Flange Replacement Ear tips Earbuds for Etymotic Earphones." These are absolutely the best for larger ear canals. **Q: can a call be muted by a button** A: This particular in-ear headphone does not have a mic or volume/mute buttons. **Q: How do these compare to shure se215 afa protrusion and noise isolation? usage is riding a motorcycle. thanks** A: I don't know anything about the Shures, but these are the only earphones I've found to work with mc riding. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Sound, Solid Build *by J***A on April 4, 2026* These earphones are well built and sound excellent.

The first thing I encountered upon opening the box was a custom measurement report. That's pretty cool. But then I looked at the report. One side had 0.7% THD, the other 0.4%. Not only is that awful on both sides, it's quite inconsistent. Upon listening to them, I heard what you might expect. In terms of tonal balance and color, not too bad, but in terms of imaging, sound stage, clarity, not very good at all. The ER2SE sounded much better. Then I looked up the numbers. It seems the ER2SE has generally about 10 times lower distortion! Yet they cost much less, at least when I bought mine. What gives? The ER4SR is their flagship "reference" IEM, which has a pedigree going back to research and audiology use, and they have BA drivers, which audiologists might know about because they are so common in hearing aids, being small and power efficient. These ER2SE IEMs have simpler dynamic drivers, but they also have measurably far better distortion performance and sound better to my ears. I rated these 4 stars instead of 5 because none of the eartips that came with them really lived up to the promise of high ambient-noise rejection and a secure, comfortable seal in the ear canal, and when I reordered Etymotic eartips, those were even worse than the ones supplied with the IEMs in the first place. I ended up going with a third party: Comply foam eartips, which work well for me. So the out-of-box experience wasn't so good, as I had to do a lot of experimenting to find eartips that work for me. Also, it's a bit lame that I paid a significant chunk of money to "upgrade" to IEMs that have deplorable distortion performance and sound worse than the ones I already had by the same company. I guess I should have checked first, but you wouldn't think a reputable company would sell you a "downgrade" positioning it as their best. ## Frequently Bought Together - Etymotic ER2SE Studio Edition Earphone - Comply Foam Ear Tips Designed for NuForce, ISOtunes PRO, Q-Jays, Etymotic Research, Westone and Shure, Assorted S, M, L, 3 Pairs, Black, Earbud Replacement Tip, Made in The USA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/123265305-er2se-studio-edition-earphone](https://www.desertcart.kr/products/123265305-er2se-studio-edition-earphone) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-22*
