    "My first pair of great portable headphones!"
    Pros - Portable and durable. Great and forward mids, punchy and precise bass, detailed highs. Nice micro details. Nice isolation.
    Cons - A little bit sibilant, somehow rolled off highs. Fat cable. Clamping force not suitable to use for extended periods of time.
    Hi headfiers!

    Well, this is my first review about any audio gear that I've ever done. Sorry for my bad english in advance (I'm from Argentina)
    First and foremost, I don't consider myself an audiophile by anymeans (and probably I don't have the right words to describe technical stuff about HP), but I do appreciate good quality sound.

    I've been like a year and half ago trying to find a good pair of IEMS and/or headphones to suit my musical taste and needs. My first pair of "good quality" iems were the Shure SE215 after one day that I tried these in my friends house, and I found a new world in SQ above any other crap that I tested before (I use these for workout mostly now) Till this days I used (and still do) a pair of Sennheiser "Game Zero" for gaming and music (paired with a Creative Sound Blaster X-Fi Surround 5.1 Pro) and I found these quite good in that time. After some time using the SE215's I knew that I wanted some closed Over-ear HP with this kind of SQ. I did one of the worst mistakes... I started looking on amazon for good bluetooth HP with "good" bass (I liked the idea of bluetooth, mics, controls, etc.) and I stumbled upon the Sony MDR-XB950BT, so I saw a lot of good reviews and then I bought these. At first I was like "wow amazing bass, so cool! I have controls, nfc, bluetooth, mic... My EDM and DnB music sound so good! These are amazing!"... but then after a couple of days I started to listen to other kind of music and I was like "voices are muffled, hihats and zimbals sound so far, bass is bloated... so weird", so after that I went back to my SE215's (wich I stopped using when I got the Sony's) and I was like "WTF did I miss! these little mother ****ers sound way better than my big ass Sony's". So I kept the Shure's and sold the Sony's.
    All this was the ticket to join to headfi and start looking for a good portable On-ear HP (I wanted some low profile HP after the "so big" Sony's that I had). My budget was like u$s200, so digging on the forum I found the Beyers T51p... and seeing a lot of good reviews I was going after these. The problem was that living in Argentina and trying to get these, the cost was too high (like u$s330 with shipping). Saddly, I stopped my quest. And then a couple of days after this, I found an offer on the Sennheiser store in my country with the Amperior's at u$s168. I knew, at that time, a little about how good the HD25's were. So after some research and with the help of a headfier (thanks analog'd!!!) I decided to go with the Amperior's. I'm glad I did it!

    So... after that long and boring intro I'll try to be more precise

    Quality 4.5/5:
    At first these didn't impress me really. The plastic headband and adjustment mechanism didn't seemed to last, but after using these like 3hs a day for almost 3 months prove that these can last for ever, and even if something breaks it can be replaced. With time I realized that the quality of the plastic parts are great. The aluminium on the cups looks good and it is very sturddy. Literally I throw them in my backpack without a case and I forget about them (these are always like prestine conditions). Padding on the cups and the headband are good, with some kind of breathtable texture wich I find comfy. The headband can split wich is good if you need more area of support. The left cup can rotate to use these as a monitoring HP (I don't really use this feature but it is good to have it) These HP have detachable cable wich is a must, BUT the detachable part use a fat 20cm long cable wich goes into the drivers and then goes to a male 3,5mm jack wich then you can use with the cables that Sennheiser provides, this is really odd and sometimes bothers me (most HP have one or two female jacks on the cups, wich is more comfortable). Anyway, both cables that comes with the HP are good, one of them has mic and iphone controls... saddly I use android, but for "pause" and "volume adjustment" it works just good and that is all I need.

    Comfort 3.5/5:
    The Amperiors have a tight fit but are light, so these are comfy for me for my daily use. At first I had some trouble getting a good fit but after some days I found the best way to use them. Maybe some people with small heads (I'm not one) may find these more comfy and easy to use than I do. The padding on the earpads are good, but it would be much better with even more padding (these have small earpads) One thing that bothers me the most is the fat cable (like I mentioned in the "quality" section) wich I feel when I walk due to the movement. It's not a deal breaker by any means, but I'm trying to be as picky as I can be in my review. I find these HP comfy enough to use for 2hs or 3hs like I do, but I won't recommend it using these for extended periods of time (the clamping force may be too much), since I use these mostly for my commute I don't care that much about comfort for extended periods of time. The Sony's that I had (MDR-XB950BT) were more comfortable, but it is not a good comparision since one is on-ear and the other an ovear-ear HP.

    Sound 4.5/5:
    First and foremost I use the Amperior with my Xduoo X2 mostly and sometimes with my cellphone. I usually prefer my DAP since it has better built in dac/amp than my phone, and these are very easy to drive (only 16ohms impedance and also quite sensitives too) Actually the Amperior + Xduoo X2 are an amazing portable duo. Taking into account that these are on ear actually it has great noise isolation. Also I can't compare these against my se215 or my ex XB950BT because I think that the senns are in another league (way better) in terms of sound quality, and I know that when these were realesed it cost u$s350, so it is not a fair comparision.

    Lows: The first things that comes to my mind to describe the bass is precise and fast (punchy). It won't have that rumble bass I got used before (the HP are not suitable for bass heads) but I came into the conclusion that I prefer a pricise representation instead of a "headshacking" bloated bass. The bass start/attack and finish fast (tight), it has more mid-bass than sub-bass. You can actually feel the "kick". I will describe these with accentuated mid-bass. Also the lows don't interfere into the mids, you can pin point where it beggins and where it ends.

    Mids: The holy grail of mids! These have foward and lively mids. Voices (male and females) and guitars are well represented. Since these have forwad mids, I wouldn't recommend them for someone who looks for a relaxed or veiled sound. It may be fatiguing for some, but for me are great since I prefer a "fun" HP. If someone looks for portable headphone with amazing mids I will recommend these without a question. The funny thing for me is that with this headphone I learned that I "enjoy" mids more than bass, and I thought that I was a "basshead" (I was wrong), now I can't bear a muddy/bloated headphone.

    Highs: The highs are a little bit sibilant to my ears (this got better after geting used to), but it has lot of detail wich I love, there is subtle details wich I never heard on some songs (micro details). It is precise and detailed, but I think that it's rolled off in some part. I can't describe it with FR beacuase I don't know that much, but I think that the treble is accentuated in some point but at the end of the FR it is rolled off. Don't get me wrong, these have great highs, and actually it is better than any other HP that I tried, but I think that the highs are the weakest points regarded to SQ.

    Soundstage: Like I said before, It won't be fair to compare it agaisnt the XB950BT, but if I must, the Amperior is like day and night. For a closed back headphone, actually it has great soundstage, it won't blow your mind and actually it is a narrow soundstage, but in some form you can pin point instruments (separation), it has more sense of width than up and down, but you can pick details in the distance. Quite remarkable for closed HP.

    Conclusion:
    I will buy these again in a heartbeat since it covers quite nicely my needs, it's portable, quite durable, not that expensive nowadays, amazing sound, easy to drive, and I don't have to be worried to break something since I can change almost any part easily. So if someone looks for a portable closed headphone with punchy bass, amazing mids (forward) and detailed highs I would recommend these for sure.
    Now I understand why after 30 years of it release date, the HD25 and their variants still rock till this days. The Ampeior follow this tradition perfectly.

    PD: I know that these are discontinued but you can still find them in some places...

    "DJ Headphone for The Masses: One of the Best On-Ear Headphones on the market!"
    Pros - small form factor, exciting fast sound, great isolation, superb build quality, lightweight, right earcup swivels, all parts are replaceable
    Cons - clamping force, treble might be a bit much for some, plasticky (but probably the most rugged plastic out there)
    Sennheiser Amperior Review
    Please Click here for Video Review:

    The Sennheiser Amperior headphone is a headphone that comes fully loaded with a bunch of features and are very practical if you just need one headphone that will last you a long time, block out noise, while sounding lively and exciting.
    A brief history
    The Amperiors is essentially a portable version of the much acclaimed Sennheiser HD-25, a legendary 25 year old, headphone especially amongst the DJ community. The Sennheiser HD-25 was known for its remarkable build quality, superb noise isolation, amazing stability on the head and its impeccably tight bass response, all of which are criterias DJ’s look for as a companion when performing and moving between events.
    The Amperiors is unfortunately now discontinued, but is still sold at a rock bottom price at the time of this review. Its been replaced by the Sennheiser HD 25 Aluminum Edition, which have the same drivers as the old HD25 but with aluminum earcups and different earpad materials.
    The following review is based on my used Sennheiser Amperior headphones, so your experiences may vary.
     
    Accessories/ Features
    In terms of accessories the Amperiors really do not come with much accessories other than the two detachable cables.  There is a 1 m IOS cable with a 3 button remote (+/- volume, and a centre button (for play, pause, rewind, fast forward) and a mic for phone calls. This cable ends with a straight jack (I prefer a L shape jack just so it doesn’t stick out of my pocket when plugged into my Ipod touch). The second cable is a 1.2 m audio-only cable that ends with a L shape jack. Both cables are rather thin and supple, and do not tangle. However, I would have wished for a thicker cable, I can see these cables fail over time, however you can easily source an aftermarket cable in the event that happens. I do wish it came with a hard shell carrying case or at least a pouch though, just to better protect these headphones, just for more assurance.

    In terms of features, the Amperiors have plenty!
    1) The first feature is that every single part of the headphone is replaceable, from the earpads, to the drivers, the headband, headband padding to cable). Replacement parts can be easily purchased from the Sennheiser website (here is the link). Also replacing the parts, is fairly easy to do (here are some links on how to replace various parts of the headphone).
    I think this is huge plus because normally when a part of headphone breaks, this would require servicing from the manufacture where there is a waiting period where you have no headphones. With the Amperiors, you avoid this hassle and you can easily buy extra parts and swap them out easily with little trouble at all.
    I had purchased a pair of HD25 pleather earpads and installed them here is the link on my impressions on them (and how they changed the sound on the Amperiors) and how to change the earpads)
     
    2) The second feature is the split headband. There is endless possibilities how much or how little you can split the headband. The rationale for splitting this headband is to allow the headband to evenly distribute the clamping pressure while increasing stability on the head. Essentially improving comfort and stability!

    3) The third feature is that the left earcup can swivel up to 180 degrees (see pictures below) allowing for one ear listening and monitoring. Surprisingly enough, the stability of these headphones is still great when utilizing the headphone like this.

    Overall: 9/10
     
    Design and build quality
    The design of the Amperiors is just a practical minimalistic yet professional design. I quite like the silver earcups (these also come in a blue version as well). Some parts of the plastic edges used are a bit sharp and less refined (for example on the headband), so it does detract it from feeling like a premium product.
                In terms of the build quality, despite the large amount of plastic used on Amperiors, the build quality is superb. The plastic used despite not being the most refined looking, it is very rugged and I was never worried about these headphones. I can definitely see why DJs use the Amperiors and HD25, just for this reason alone.  Also the earcups on the Amperiors are made of an anodized aluminum, and it appears to be scratch proof as well. Also, stated before the each part of the headphone is replaceable, a welcome feature for those hard on their headphones. Something to note is that, the earcups are rather loose and at times it can extend and retract more easily than i'd like.
    (To remedy this issue,  I added a layer of tape inside the adjustment area to prevent it from sliding out of place. Now, the headphones will never slide out of place unless intended and the tape remains out of site)

    Design Overall: 7/10
    Build quality Overall: 9/10 (which a bit more metal was used, but the plastic is super rugged)
     
    Comfort and weight
                The earcups swivel to fit anyone’s head and ear shape and the Amperiors was meant to have superb stability and isolation when moving around outside or in the DJ booth. So comfort does suffer, along with the fact that these are on ear headphones (which traditionally are not the most comfortable headphones to begin with, having to rest and press against your ear to maintain seal).
                Using the stock velour earpads, I was able to use these for about 1.5 hours before I had to take them off, due to my ears hurting and starting to sweat at about the 40-50 min mark

    P1020175.jpg
    Comfort Velour: 7/10 
     
     With the HD25 pleather earpads, I was able to wear them for about 1 hour before I had to take them off, my ears hurting and began sweating quite a bit starting at the 20 minute mark. 
    Both earpads are about the same in terms of padding but the velour earpads are much more breathable and overall more comfortable than the pleather. The material used on the pleather earpad seems kind of papery as cited in my impressions video below.

    Comfort Pleather: 6/10

    In terms of weight, the entire headphone weighs in at about 160grams, very lightweight on the head and around the neck, and I did not feel the weight of headphones on my neck even after extended listening periods.
    Weight: 9/10
     
    Isolation and Portability
                Whether your using the velour or the pleather earpads, the isolation on is superb! It is easily class leading in the category of on ear headphones. You can definitely use these in your morning bus and subway commute. Its actually quite scary how good the isolation is, it rivals many IEMs/ earphones.
                I did find the pleather earpads isolating more on my subway commute than the velours. 
     
    Isolation Velours: 8/10 Isolation Pleather: 9/10
     
    In terms of the portability, the Amperiors are small when on the head and when around the neck, there is no restrictions in head movement. But I did notice that when putting these around my neck, the split headband joins together and for me anyway I would have to take off the headphones re-split the headband before putting it back on my head (see video for a clear explanation). This is a mild annoyance but I’ve grown use to it now.
     
    Portability: 8/10 (which it folded up or flat)
     
    Sound quality: The Amperiors have a mild V shaped sound signature, that never sounds bloated in anyway while being a very lively and exciting. Its quite remarkable how fun it is while being so clear and articulate.
    The following is based on my opinion of the Amperiors with the stock velour earpads unless otherwise stated.
     
    Bass: The bass is where this headphone absolutely shines! The bass is warm and north of neutral. That said the Amperiors have absolutely the tightest, quickest bass response of any headphone or earphone I have ever tried before. If I had to make an analogy, you can think of the Amperior’s bass being a while (like a lion tamer) its quick, its precise, it’s powerful, yet it never overstays its welcome.  The midbass of the Amperiors is chesty and slams with authority without sounding bloated.  You can throw the most complex bass lines on the Amperiors and they will reproduce it so cleanly and effortlessly. An aspect that DJs need when beat matching.
    I did however have two complaints with the Amperiors in terms of the bass.
     
    1) The first was that I would like the bass to be a bit more north of neutral, nothing drastic maybe 1-2 db more. Then it would be basically perfect for me as a portable on ear headphone.
     
    2) It doesn’t have the greatest extension all the way down there in the subbass, and it does roll off a bit there. So you won’t get the rumbling enveloping bass.
    With the pleather earpads, I did feel the bass was slightly boomier, and less controlled. It did lose some of that lightning quickness. It was nothing extreme and but was evident immediately. However, the differences is less noticeable when outside with ambient noise present
     
    Midrange:  the Mids are a bit recessed but nowhere near the same extent as the Sennheiser Momentum On Ears. Vocals especially female vocals are more forward. The vocals have a thinness to it, which definitely helps in terms of clarity. While remaining perfectly clear of bass, while being full intergrated in the mix, something I felt wasn’t executed a well on the Momentum On Ear. Female vocals in particular sound great while retaining a lot of their character and “naturalness”. However I did feel that some vocalists sounded a bit overbearing from time to time because of how forward the vocals are in the mix. So take heed if you’re sensitive to this.
     
    Treble: Again the treble similar to the rest of the sound signature of the Amperiors is forward and aggressive. Some users have noted that they seem harsh and I can see that for some people that are sensitive to high frequencies, the Amperiors are just not the headphones for them. I did find them a too bright at first, it has probably the brightest treble of anything I’ve used before so it did take some getting use to.
    Even now I do find the treble a bit bright for my taste so it doesn’t lend well for long term listening as your ears do fatigue over time (in addition to the physical fatigue from the clamping force).
    The treble though is very well extended and articulate and very fast sounding, perfect for rock, and more electronic music. That makes everything lively and engaging.
    With the pleather earpads I did find the treble edgier and “more raw-sounding” and even more exciting compared the velour’s (which sounded smoother in comparison).
     
    Soundstage: This is one area that I’m a bit disappointed with. The soundstage is quite closed and in your head. Though the Amperiors do a good job placing instruments in this space, I would like it if it was a bit bigger, at least similar to the V-moda XS in this category, which sounds like a small room.
     
    Overall: 9/10 ( the treble might be a bit hot for some folks)
     
    In conclusion, I think Sennheiser has absolutely hit a HOME RUN with the Amperiors. Its spectacular in terms of build, isolation and sound for a portable on ear headphone. I do wish the design is a bit more modern looking, and the comfort can be a bit of an annoyance for extended listening but all in all I can easily recommend this to anyone, especially for those that go through earphones/headphones every few times a year, good luck trying to break the Amperiors!
    awry and Savant like this.
  3. Armaegis
    4.0/5,
    "if you liked the HD25, you'll like the Amperior"
    Pros - rugged and utilitarian, good sound at this price, isolation one of the best, practically industry standard and most people know what it sounds like
    Cons - good isolation comes at the cost of high clamp
    Just a point form review... really just notes for myself comparing vs the HD25-1-ii. If you want something with more sonic impressions, read any other Amperior or HD25 review below or the excellent one over at InnerFidelity.
     
    pads: Amperior has this supple pleathery material which is way nicer than the HD25 pads and more comfortable
    isolation: but somehow the HD25 pleather pads isolate better
    clamp: really the same
    build quality: Amperior clearly better in every way with nicer cups and cable assembly (and changeable cables with iDevice capability)
    sensitivity: the Amperiors are a bit easier to drive
    impedance: much lower than the HD25, which may be an issue with amps that have a high output impedance if you're the sort that worries about damping factor
    amping: not really needed, nor much of a difference noted
    bass: midbass still humped like the HD25 but to a slightly lesser degree
    midrange: same 'ol
    treble: again a tiny bit cleaner than the H25
    overall sound: it's really just a slightly cleaner sound overall
    upgrade from HD25? eh... if you already have the HD25 I don't really see the point unless you want the colours
     
     
    Extra comparison of HD25-13 vs HD25-1-ii...
    pads/isolation/clamp/build: all exactly the same as HD25
    impedance: boom we're at 600ohms
    sensitivity: not surprisingly lower than the HD25, but actually not by much; you can still get plenty of volume from a portable dap
    amping: makes a difference, but don't go breaking the bank for it; it's a mild improvement and more useful here for the headroom
    bass: take the HD25 midbass hump and stretch it out lower
    midrange: same 'ol
    treble: less wobbly than the HD25, more "hifi" but less useful for DJ use where you want that extra sharpness
    overall sound: more even response across the frequency range
    upgrade from HD25? only if you already have an amp, otherwise stick with the regular one
