Description

The ER2SE offers Etymotic’s renowned passive isolation, providing 35-42 dB attenuation. You will hear all the details in the music with lower volume levels that are safer for your hearing. 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 is ideal for sound engineers, audiophiles, and consumers on a budget, who are looking for in-ear monitors that are easy to drive while offering accurate audio reproduction.

Which ER2 is right for you?

Both ER2 models, the ER2SE and ER2XR, use the same low-impedance dynamic drivers. That means they are easy to drive, and no amplifier is required. The only 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. The rest of the frequencies are practically identical to the ER2SE.

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.

ER2XR is favored by those who enjoy the extra bass presence and body when listening to their music. The extra bass is done tastefully without turning the ER2XR into a bass heavy IEM.

Frequency response graphs and Etymotic’s target:

Etymotic’s target frequency response graph represents a “perceptibly flat” frequency response. Our goal is to have a flat frequency response curve when the music notes hit your eardrums. To achieve that, we need to account for the resonance inside the average ear canal, since IEMs bypass the outer ear structure. The result is the need for higher SPL in the 2-5k region (lower treble) for compensating said resonance. That is the reason for the “hump” in that region.

The target curve that Etymotic is using for tuning our IEMs differs slightly from the Harmon preference curve. It was developed in-house more than 20 years ago, leveraging on our human hearing expertise and acoustics research.

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.

My dogs favorite
Size: Small, Color: Bunny
I need this toy! It is my dogs favorite. She even takes this on walks. Ive replaced this on 3 times because it was “eaten” by my daughters dog. I keep it put up and Georgia constantly goes to the spot I keep it and is expecting me to give it to her. Please restock soon

My doggo's go-to toy!
It's not the most durable of toys (she's on her third in five years) but I will buy her as many as she needs because she is OBSESSED with it!

Defective toy and inconsistent quality.
Size: X-Large, Color: Raccoon, Size: X-Large, Color: Raccoon
My initial review was 5 stars based on my experience with a previous order (blue raccoon) and the fact my puppy was immediately interested in it. However, I did not give it to her to play with until this past Friday (May 21, 2026) because she had the first one I bought. In a matter of 2 days the seam on the back and at the base of the head unraveled and all of the stuffing was scattered all over the room. I thought I’d found some good, high quality, toys for her but apparently this one was defective because the first one had had a lot of use and I’d still in decent shape. This is too much money to pay for a dog toy that only lasts a day or two so be advised they aren’t all good.

Bigger, louder, crinklier, softer, than expected!
Size: X-Large, Color: Rabbit
My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash. Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)
