Cons: clamping force, treble might be a bit much for some, plasticky (but probably the most rugged plastic out there)

Sennheiser Amperior 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 Its been replaced by the Sennheiser HD 25 Aluminum Edition, which have the same drivers as the old HD25 but with aluminum earcups and different earpad materials.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.

 

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 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 anodized aluminum, and it appears to be scratch proof as well. Also stated before the each part of the headphone is replaceable, so very easy impressive.

I would say the earcups are rather loose and it can easily extend and retract ( I added a layer of tape inside the adjustment area to prevent it from sliding out of place.

 

 

 

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

    

 

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!

Great review man. In total agreement with just about everything you wrote regarding build and sound.
 
Believe it or not, the original HD25s had an even faster PRaT. But these sound better overall in other aspects.
 
And don't worry about the plastic parts. These things can really last. Have an Amperior now but use to own one of the older full plastic ones and those still looked almost like new the day I sold them even without a daily case to carry around etc.   
Thanks for this review, Tom22!
