Sennheiser HD 25-1 II Professional Headphone Reviews


Long-term review


Pros: Good isolation for trains, buses, great bass, shows up clear differences in source file qualities

Cons: OK, a bit geeky but who cares

Durable - replaced pads after two years - i use case supplied with phones for storage

The perfect portable HP


Pros: Sound quality, impact on bass and drums, detailed and refined yet fun sounding, completely user customizable/ detachable

Cons: 100% plastic, light microphonics, revealing, imaging and soundstage

I bought the Sennheiser HD 25-1 (adidas) after my ATH-M50 had a loose connection and i had to return them. Though I loved the M50's, they made me realize that a headphone is not all about sound quality. Their isolation just didn't do it for me, and the pleather pads got my ears sweaty all the time. The HD 25-1 finally does everything I need it to do. The isolation is top notch, and the velour pads are more comfy then pleather while not getting sweaty. Sound: The sound quality of the HD 25-1 II was horrible out of the box, but they got better after a few minutes. I didnt notice much of a burn-in process after that, and was quite disappointed with their sound, cause the only thing they...

Amazing headphones


Pros: Portability, ability to take any music thrown at it

Cons: initial comfort, stock pleather pads cause sweat issues

These headphones are great. I listen to mostly metal and have listened to Grado's mostly because of it, and these phones are really similar to the grado sound; I can see why people refer to these as the equivalent to a closed grado headphone. It's funny to me how different these phones are to the description of every other sennheiser headphones. Every review for the hd 600 or 650 talks about their laid back nature, while the hd 25's are anything but laid back. indeed, they are very forward, and for metal and rock, this is just what the doctor ordered. Bass-y music sounds great too, these headphones can really bring out the lower end of the sound spectrum. My only gripe with them is the...

Not so satisfied [EDIT]


Pros: Isolation, durability, spl

Cons: Tiny soundstage, Dark sounding, not very much detail, very uncomfortable

I have had these headphones for a couple of days, and used/tested them intensely during that period. I have a pair of mackie mr8 mk2 studio monitors, so this is the sound I am used to. The sennheiser HD25-1 II are extremely populair, and this is one of the reasons i bought them, yet I was not satisfied at all. First of all, the sound stage is extremely small, it actually sounds more like everything I was playing was in mono instead of stereo. Also the headphone lacks in treble, and really does not have a lot of detail, this headphone is everything but balanced, so to call this a studio headphone is just wrong.   Don't get me wrong, it sounds good, has a lot of tight bass,...

Surprised the first time I put one on, and surprised every time I listen to something new!


Pros: Awesome frequency responce and good isolation.

Cons: Feels weak and fragile.

The first song I listened to with the HD-25 (like with any new pair of heaphones) was Dizzee Rascal's "Bonkers". This is the one track that I know that feels like every audible and inaudible frequency is used in the bassline... It just surrounds you and therefore can be used as a benchmark tool to test audio hardware.   And boy was I convinced instantly, also the isolation is extremely good so all of that really set me on my way!   Definitely recommend!



Pros: Punchy bass, agressive, detailed sound, very quick, indestructible, light

Cons: Can become uncomfortable for some, questionable aesthetics

The HD25s are a legend, really, so I'll just say I love the sound. They push all my aural buttons, with a fast, agressive sound (not quite Grado-like as some would say), punchy bass and great detail. I feel these things just "throw" the music at you, making you listen. Don't know how some people could call them boring, really. They have a solid bass, a dip in the midrange which gives them a certain natural feeling, free of colorations, and somewhat sharp treble. Nothing is overdone, nothing is missing. Soundstage and neutrality might be questionable to some, the design certainly is, but these cans are something you really have to try, especially for rock, metal or rap.    ...

puzzled by good reports..


Pros: small, sensitive light and good sound proofing

Cons: overwhelming character

I have Grado SR60, SR225i, HD650 and HD25 II's, with an iBasso headphone amplifier, fed by an ipod dock cable. I principally bought the HD25's as a monitor headphone for video use but thought I would burn them in for 100 hours and see what they do with music. The reproduction is not what one would call subtle, the extreme frequencies are pronounced and there is little impression of ambience or imaging. It is like it is trying too hard to please.  I can imagine, for that reason, it suits loud rock music, but it tramples delicate good recordings.  The cable picks up some microphony.

Portable juggernaut


Pros: overall built quality, sound isolation

Cons: the cable microphonics, sound quality for money

Hi, just a quick mash-up of what I wrote somewhere about HD 25.   *Clamping, isolation - When I'm commuting for almost 4 hours it can be quite annoying. On the other hand I was angry that my ATH-SJ5 has weaker clamping force after a year, thus less isolation, it would easily fall off, so I should be happy with what I have now. The only problem is that I have to have full-sized, cheap headphones in both places where I live during the week. Otherwise I'd have to buy 2 good home headphones, or carry one with me while commuting between those 2 places....(as using HD 25 at home is bad for the clamping and you won't be able to endure the clamping for several hours).   *Earcup size...
