Designed for the demanding audio specifications of live performance, the SE425 is engineered to provide reference quality audio. Hear all the details of your music with Dual High-Definition MicroDrivers that deliver an incredibly accurate and balanced listening experience.

Sound Isolating Design

Comfortable sound isolating sleeves block up to 37 dB of ambient noise. Sound isolation technology prevents outside noise from interfering with your listening experience, whether onstage or on-the-go. Shure Sound Isolating Earphones require a proper fit to achieve the best sound.

Unmatched Personalization and Comfort

The SE425's ergonomic, professional design provides a lightweight, low-profile shape with an optimized nozzle angle that's designed to rest comfortably in the ear. The over-the-ear configuration also keeps cables out of the way.

Detachable Cable with Wireform Fit

  • Durable Kevlar® reinforced cable allows easy replacement or customization.
  • Formable wire ensures secure placement, and over the ear configuration keeps cables out of the way.
  • Gold-plated MMCX Connector has a lock-snap mechanism allowing 360 degree rotation for comfortable fit.

Premium Fit Kit

Sound Isolating Sleeves
The role of the included sound isolating sleeves is twofold: blocking ambient noise and ensuring a comfortable, customized fit. Because every ear is different, the Fit Kit includes three sizes (S, M, L) of the flex and black foam sleeves as well as 1 pair of triple flange and 1 pair of universal fit yellow foam sleeves. Experiment with the size and style that creates the best fit for you. A good seal is key to optimizing sound isolation and bass response as well as maximizing comfort during extended wear.

Carrying Case
A durable and compact carrying case is included to provide a convenient, tangle-free solution to store and travel with your earphones.

1/4" Adapter
An 1/8" (3.5 mm) to 1/4" converter for all Shure earphones that offers a solution for home stereos or other applications with ¼" jacks.

experiment with fit, patience pays off
Similar IEM background to previous reviewer. I had being using Etymotic ER?6is for over a decade, when finally they gave up. Since the ER-6i is no longer available, I wanted to check what other IEM options were available before before going with the ER4.

Having worked with Drew before, I called him up looking for a recommendation. After we discussed musical tastes, other headphones I like, and usage requirements, he suggested the SE425. After receiving them, I found the sleeve fit package both a very nice inclusion, and a bit overwhelming.

It took me a long time to find the ones that provided the most comfortable fit and isolation I wanted. I even tried the Etymotic frosted triple flanges, since I was most used to these. I finally settled with the gray soft flex sleeves (small).

I mention this, because for some people it may be challenging to find the right fit - perhaps a user may need even to go as far as 2 different sizes of the sleeve they like the best. Shure provides an inclusive range of sleeves; take the time to experiment and find the right one for your ears. It will certainly improve the enjoyment of this headphone. I felt underwhelmed by the headphone prior to finding the sleeves that worked for me.

Like the other reviewer, I suffer a bit from ear wax production. Apparently, this is more common than I thought. Haha! So it is nice to get a good seal and not have the sleeve set so far into the ear canal, like with the Etys.

With the best fit for me, these headphones are very musical and balanced in their presentation. For my varied musical tastes, they are a very good 'all-rounder' headphone. The bass is not over-emphasized, which is how I prefer it.

I've since added the Black Dragon cable and it is has certainly added to the enjoyment of this headphone. I also prefer the Dragon cable over the ear fit to the included cable.

These headphones are very easy to drive and can be used directly out of a portable player. I've used them with two portable headphone amps and two different results. With the HRT microstreamer DAC/headphone amp, I find the usable volume range very small, so I err on the side of caution and the lower volume setting.

For me, the SE425 pairs better with the ALO National headphone amp. The selectable gain undoubtedly helps. I am discrete with the volume, but the National allows me to find a more ideal volume level. Of course, I am losing the DAC in this scenario. I use this amp mostly with my iPod Classic and Blue Dragon 30pin to 3.5 mm cable.

Recently I tried these with my home stereo, since all my full sized headphones are open air. I used the Shures with a Naim Headline2 headphone amp (uses a Naim FlatCap XS power supply) and Black Dragon 1/4" - 1/4" extension cable.

I was really pleasantly surprised with the results! The headphones scale nicely to the source and amplifier upgrades. Using them in this context has certainly quelled my desire to get a pair of closed cans. But I may move up the Shure IEM ladder.

It is easy to recommend these to a person that is looking for a well-rounded IEM. Just take your time trying the different sleeves. Even if you start with one that fits from the start, try the others. They just might further enhance the musical enjoyment.

Sound is sweeter when YOU control it.
My Etymotic's were gone. The constant replacement of the tiny interior filter killed them. Painful since with this loss went my ability to shut out the world when needed.

I needed a new pair of isolating earbuds if I was going to do something I love - work in public places like restaurants and airports. This public display of affection is critical.

I write so much now days can go by when I speak to people more on computes than IRL (In Real Life). Working in public makes writing feel less solitary, less alone.

As much as I love to work in public there is a cost. I inevitably sit next to the conversation from HELL. Today it is someone's brother is in jail for some crime and they are trying to figure how to game the system to get him out.

Instead of hearing the rest of THAT conversation I have my Shure 425s in and miles on. Without these magic earphones no way I write this review or finish the Content Marketing Is Like Speed Chess blog post I've been working on.

The Shure's are a tad strange looking. Their ergonomics took a little getting used to since you kind of screw them in your ears. Those "screw-like" ergonomics is why they isolate so beautifully without being half as deep in my ear at the now RIP Etymotics.

Another BIG plus to not being so deep in my ear is I don't have have a problem with wax build up with my Shure's. Embarrassing to admit I am an ear waxer (lol), and that build up on my old phones did them in.

The Shure 425s sit up higher in the ear thanks to that "screw-like" twist and so they are not subject to wax build up (lol).

The sound is so warm, large and complete. The isolation is amazing too. I'm watching the convict's family like a silent movie with Miles Davis supplying the sound track. Magical is not too strong a word for my Shure 425s.

Magical is not too strong a word for Moon Audio either. Drew and Nichole are amazing. They found out what kind of music I like, heard my sad story about my Etymotics and then made this prescient suggestion.

Next I want some of Drew's Dragons as I bet adding his cables clears up the highs and lows even more and so further isolates the conversations you just don't want to hear, and so allows me to work in public.

Thanks Moon Audio, Drew and Nichole. You guys rock.
