    "One of the best option for whom always like to have music"
    Pros - Isolation, spacial expression,
    Cons - subdued bass, too referential for some music genre like rock or metal
         Now, I own Sony MDR-EX800ST, Etymotic Research ER-4S, and Ultimate Ears Triple fi. 10PRO as daily use IEM. But still SE425 is my all time favorite for its accurate relaxing sound. I am a guy who always like to have music. I need music for walking, working, reading and forget about daily life. This is open like canal earphone. Sound is not too closed, bass is weak but deep, treble is transparent and relaxing. 
         I believe this SE425 has the best cost performance as your life partner through my 6 years of experience with this IEM. Of course, if you can afford over 300$, that is different story, but I know not many people can really dare to pay that much from their very first time to start expensive IEM. SE425 will be the good start for the wonderful audiophile world for who has first try high end model, and it will be the great reference IEM for all audiophile too.
         Ultimate Ears Reference or Reference Remastered have slimier sound tendency. They are all flat, accurate, and boring (with not negative meaning) . SE425 is just like them. It has typical referential sound with easy, and highly qualified beautiful mid sound. Probably I should paraphrase boring as relaxing or referential sound. I have learned a lot through this IEM about the sound of music itself. This honest IEM told me how quality of the audio source affect to my listening experience and overall satisfactions. This is the great IEM overall.
         I will still update in later when I get good word to describe this my favourite item.

    "Takes time but finally getting into it !"
    Pros - After some adaption, some sort of refinement, tight base, well sorted mids, and non fatiguing highs, well built
    Cons - They don't like to be pushed, timbres not that realistic, I sometimes miss my $40 Zero Audio Temore's honesty and energy
    It was a big investment for me. I was very pleased with the fit of my SE215 not so much with the bloated bass section and the warmish signature.
    At first, I was disappointed, switching from Tenore's, the shy sound appeared muled and even more worried by tweaked timbres (Only classical music in my Fiio X5II).
    After 2 weeks, my judgement had to be revised.
    First of : don't push the volume ; they don't like it. They have enough details to cope with it.
    Anyway now, I rather like them, especially when music has complex messages like, let's say, a Bruckner's symphonie. The bass are so clear they never interfere with the rest, they are precise and tight, just the way I like. The rest of the spectrum is well defined never fatiguing with no sibilance. It's very refined, the instruments are well placed and well balanced.
    What remains from my first impressions are the timbres. Hard to describe but let's say I know how a cello sounds and I am not convinced the IEM's are fully accurate. On big ensembles, it's not a problem but on a Bach's partita for solo violin it's a bit more annoying. It's smoothed out and veiled at times.
    It all depends on the recording, as usual...
    Whatever, the more I use them, the more I like them. Four hours of Wagner Siegfrid ? No problem, the message is clear, articulated. I might not have found my perfect IEM's but I get Shure's intentions.
    I wish I could compare them with dozens of others in the same price range to be more precise on my impression, the music lover rather new in the headphone world. 
    I didn't find the Graal but will try hard.

    "Shure SE-425: Mid-Centric gold with little to desire"
    Pros - Fantastic mid centric dual driver, exceptional clarity, godlike isolation, Durable detachable cable.
    Cons - Can be difficult to determine right tips for best seal, highs may leave something to be desired.
    Hello fellow head-fi members. This will be my first official review of a product that I have published. As such, I would appreciate any input you can provide to allow me to make my review better. Likewise, if you have any questions regarding the SE-425’s. Let me know, as these are my daily IEM’s at the moment, I can usually answer the question or at least find out. With that said, let’s begin the review!



    The Shure SE-425 is one of Shure’s higher tier IEM products, having only the SE-535 and SE-846 above them. The 425 uses a dual balanced armature setup with passive crossover. They also sport one of my favorite features, the detachable cable. This means that the cable can be replaced if damaged, or simply upgraded if you want a better cable. Before we begin the real review, let’s take a look at the specs.


    P_20150921_133146.jpg P_20150921_133204.jpg P_20150928_103804_SRES.jpg

    The box for the SE-425 is your standard windowed retail box. Nothing hugely fancy, but more than enough information for someone to make an educated decision on the phones and have the real specs (You know, that information Bose doesn’t include). Inside, you will find the following:

    1. Warranty card
    2. Instruction manual
    3. Hardened fabric style carrying case
    4. Ear wax picker
    5. A plethora of different eartips (more on this later)
    6. 3.5mm to 6.3mm adapter (gold plated)
    7. And of course, the headphones

    The Shure SE-425 is built in the same type of housing found on pretty much the entire SE line. The plastic seems hard and resilient, but is still plastic regardless. It doesn’t feel as durable as the RHA 750’s. nor is it as sexy as the JVC FX850. But it does the job. The cable feels very durable, which is ironic as one of the big selling points for me was the detachable cable in case the cable was damaged.

    There are two main worry points for me on this device. The first being the nozzle or tube that the ear tips are attached to. In fact, I managed to break the nozzle on my first pair when trying to remove the originally installed ear-tips. There are a number recommendations on how to properly and safely remove the ear tips. However, I did not read these recommendations and proceeded to grip with all of my might to remove them. This resulted in a cracked nozzle and a 2 week exchange period without my new toy ☹.

    Shure recommends a few methods, including putting the headphones in the freezer for a bit to break the seal from the factory tips. I found this helped remove the tips. Once the originals are removed, things are easier (but not too easy) to change. As a personal recommendation, if you know the factory tips are not going to work for you, simply cut them off with an x-acto knife. This is an easy way and allows you to avoid the headache.

    P_20150928_104331_SRES.jpg P_20150928_104525_SRES.jpg

    My other concern is easily avoidable. This concern is with the detachable cable, or rather the connection. I love that these cables can be replaced easily. But, the type of connection leaves the male connection on the monitor. This means you have a tiny pin that can easily be bent (and not so easily put back in place). To avoid this, simply avoid detaching the cable. If you need to detach the cable, make sure you are attaching the cable completely straight. Issue avoided!

    Some people report that the design of the Shure’s just simply do not fit, either not making a complete seal or they have a short length of ear, making the IEM not fit completely. For me this is not the case. If you find that the seal isn’t getting it done, try a different tip. If they simply don’t fit… They just don’t fit. There isn’t much to be done.

    SPECS: (from the box)

    Speaker type: Dual Hi-Def Micro Drivers (Balanced Armature)

    Frequency range: 20 Hz-19kHz

    Sensitivity: 109 dB SPL/mW

    Impedance: 22 Ω

    Noise Attenuation: (sound blocking) Up to 37dB

    Cable length: ~63.75 inches (162 cm)


    I’m going to split this portion into a few categories to make this a simpler read. It is worth noting that before writing this review and testing, the headphones had roughly 100 hours of burn in. If you find something missing here that you wanted to know about, please let me know and I will try to add it into the review.


    Being that these are dual driver IEM’s, they have a dedicated woofer for each ear. Provided the fit is right (more on this later) the Bass is well placed. It is tight and concise, and usually extends well enough. On my computer the Bass is fantastic, but for some reason when using my Fiio X1 the bass is almost non-existent and needs to be EQ’d to show. Even then, the quality of the bass is not as expected. This issue, does not seem to replicate with my Zenfone 2. Perhaps this is due to issues with the Fiio X1?


    As far as I’m concerned, Shure is god in this arena. Details are clear and crisp, making for a weird experience when you didn’t realize a specific background instrument in songs you have listened to for years. You can hear the subtle breaths in between lines, Vocals are fantastic, Guitars are all on point, to a scary level almost. Overall, practically perfect, with a forward lean on the mids.


    Probably the weakpoint in the phones. Not enough to complain in my opinion. But some people will want more here. Highs are theye, they sound proper, but with a lack of proper extension. The highs don’t carry (last) as long as I feel they should. To me it still seems to capture the life of the highs, just not to a degree where a song full of mainly highs will be replicated properly. This isn’t so much an issue with me, as most of my songs live in the mid with some high details.


    While the following doesn’t have to do with the product abilities to reproduce music, I feel it needs to be in this section. The first is Microphonics (noises from the cord rustling), this is practically non-existant. This is likely due to the over the ear style, but is almost not worth mentioning.

    Isolation is FAN-TAS-TIC… BUT!-only if the fit is right. This is key! Not only to isolation, but for the proper sound. Perhaps this section should be at the start of the sound section, but it’s too late for that. This IEM can go from sounding superb to sounding terrible due to improper fit. Find the right size, and stick with it. I find that the Shure olive mediums are the winner for me (Ironically, the ones that come pre-installed). The grey tips didn’t seem to get as good of a seal for isolation. The yellow foam are actually great (possibly better than the pre-installed for me), but they tend to pull a lot of ear wax from me and are more difficult to clean… To me they are not worth the hassle. There is also the white triple flange that like to violate my cranium. Ultimate seal from these, giving even more bass, but I just cannot handle the cranial invasion these provide. Your mileage may vary…


    Regardless of which tips you choose, make sure they are right, and that you get a proper seal. During the burn in period I had to take a four hour flight. As luck would have it, I was placed on the wing, next to the engine, with a crying two year old behind me. So I prayed and squished down the foam of the Shure olives and placed the IEM. After getting both in it was incredibly quiet. Then, after hitting play the world went mute. No crying baby, no engine. Just the soothing sounds of music and a smile across my face.  I particularly enjoyed watching the increasingly frustrated face of my neighbor as he attempted to deal with the baby with an infinity lung. It will take time to really figure out how to get the phone in properly, if this is the first of the style you have owned. But once you figure it out, it’s a simple installation for plenty of comfort and sound!


    Soundstage has always been something of a difficult thing for me to understand when using IEM’s. For me, almost every IEM has a very close soundstage. This is not to say that it is non-existant, more that I cannot comprehend the stage. Musical separation is fantastic, and each can be picked out separately. Vocals from multiple people is easily distinguished. But for me, when using IEM’s I have always had issues visualizing an actual stage to them. I don’t think this is an issue for the headphones, but more an issue that I have. In the end, the things important about a soundstage are all present and fantastic. Sorry I can’t help more with this portion.


    The Shure SE-425 is a great all-round IEM. The bass is tight and concise, musical separation is superb, and the mids are solid gold. The bass can be lacking if the seal is not correct, so make sure your using the right tips. The treble may leave some things to be desired. But overall, for the price these can be obtained at (can be found regularly at about $249.99 despite the $349.99 MSRP) they are a great deal for me.
