Sennheiser HD25-1 II
I bought these for $129.95 from I owned Shure SRH750DJs before this, but found them very uncomfortable due to high clamping force and the headband which becomes flat upon wearing.

Sound quality is excellent. The sound is well-balanced with a slight reduction in midrange emphasis, have good clarity and detail, and are quite transparent when it comes to sources. The bass is tight and accurate. These are very comfortable, since they are very light. They almost feel like toys. Not only these headphones are good for studio use, they're the perfect portable headphones too. You see a LOT of DJs and cameraman/audio staff using these headphones.

Pros: Tight bass
Detailed sound
Comfortable, very light
Cable is not ridiculously long
Isolate well

Cons: Uncomfortable when using the headphones with glasses on; the problem can be fixed by having your glasses' legs sit a bit above your ears.
A bit pricey at normal price

Great sounding headphones with a catch
These headphones are designed to have replaceable parts. The cable can be replaced to shorter or longer lengths (and even barrel or L connectors) and practically every piece is supposed to be user replaceable.

Imagine my surprise when one side crapped out on me- and after having to special order a new cable (which took about a month to arrive from Europe)- it turned out that the actual capsule needed replacing. After having no luck (or interest, it seemed) in being able to get any salesperson at the local Long & McQuade to follow-up on getting the part ordered, I went on-line and only seemed to find replacement capsules through Europe. With shipping it would likely cost almost as much as getting a new set of phones in North America; which is what I ended up doing.

The sound quality is great and the headphones have good isolation. It's nice that the cable can be replaced (I changed it once before the capsule crapped out). The cable seems to be easier to get but if you plan on getting any other part for the headphones (and are outside Europe)- you're probably better off buying a whole new set of headphones. The saving grace is that, as long as the same capsule doesn't crap out, I can gut the old set to keep the new ones running. In hindsight I wouldn't have bought these headphones if I could spend a bit more money and get a set of headphones that were more durable and had replacement parts I could easily order.

I agree with most of the points said above, these headphones sound great, especially so for live tracking and louder sources. For more subtle tasks like say overdubbing acoustic guitar there might be a tad too much bottom end but I quickly got used to this for the advantage of excellent isolation.

In terms of comfort I find the HD25-1 II 'o.k' but rather difficult to adjust to your own needs because of the relatively small size of the cans. Maybe others don't feel that way as I'm a certified 'headphone neurotic'......

The main drawback for me though is the cable length, a joke to be honest! I just can't understand how a manufacter can do this for a supposedly professional product. Of course you can use extension cables but in my experience this is causing lots of problems with dropouts and it's a PITA in general. I had a tech change the cables on all my HD-25s (I have 5 pairs of them) but I realize that the cable he chose is not ideal and has a tendendency for the 'spaghetti syndrom'.

EDIT: Thanks to the reviewer above, I just learned that Sennheiser actually sells longer replacement cables for the HD-25 line. But watch out for the price wworried Sennheiser HD 25 SP Ersatzkabel 3,5 mm

CONCLUSION: If these cans were a bit more flexible to set up and would come with a generous cable length it would be a killer product.

Even with these reservations these are basically the only headphones I use in my studio and I had drummers show up with their own cans eventually prefering them for their sound and excellent isolation.

ADDENDUM: Please be aware that there is a whole line of 'HD-25' models that Sennheiser offers at different price points. So be sure to get the ones you really want and yes, the labeling is confusing. (Why not call the 'Basic Edition' say HD-24 or something?)

I thought I would share my view on these cans as well.

I replaced these with Technics RP-DH1200, which had served me quite well for a few years, however these where quite heavy, and damn, it's so nice that these cans are much more light compared to the Technics. And even though these are quite lightweight they still feel very solid and the build quality is great. Every part is replaceable so if something should happen you don’t need to go out and buy a whole new set.

I mainly use the cans for DJing, but also a bit for producing, and while the sound quality is probably isn't the for studio use, it is quite nice. The detail in these cans are pretty impressive, the bass is nice, but not overpowering, and the highs are great, the mids are pretty decent too. The sound quality does seem to be a step up compared to my Technics.

Now one of the most important things for me is the isolation as I use these for DJing in clubs, and these cans do it pretty damn well! Quite a lot better than the Technics I actually didn't expect such a big jump on this.

Regarding the cable as mentioned in the reviews above. Well I bought the HD25-C II version, which is the exact same version as the HD25-1 II with one difference, that is the cable. This version comes with a coiled cable, still 3 meters, but as it’s coiled you can actually extend it quite a bit over the 3 meters, and this is awesome, as you don’t have to take them off all the time when finding your records or what not in the DJ booth.

Comfort on these are quite good, and I have no problems using these for a few hours, however as with any cans I do get tired of having them on for an extensive period of time, but I haven’t tired any headphones that doesn’t do that.

The headphones come with a small bag for transporting the headphones and to be honest on this point I am quite disappointed. The quality of the bag is not as good as I would have expected, it’s very thin, and you might as well not use it. Another thing is that the Left and Right icon is placed on the cables and these are very tiny! They are almost impossible to find. Of course this is not very important as you only really need to find it once but come on.

Otherwise very happy with them, great sound, great comfort, amazing isolation and they are very light while still having a high build quality.

Great headphones for DJs but don't expect to be able to mix a song with them.
These headphones are great for specific purposes.

They are well respected by DJs around the country for DJing. Why? Because they have excellent isolation and cut out a huge amount of outside noise so if you're DJ in a noisy club, you can hear your headphones properly. They also have a very large amount of bass and subs which is important for DJs to hear when mixing live.

If you are thinking of buying them for mixing on in the studio, forget about it. The same big bass that is good for DJs will throw off your mix and make it hard to hear what you are doing properly. They don't have a flat frequency response which is what a monitor speaker should have and what you might think a monitor headphone would have. Even using them for singers or other musos in a studio would be a problem if you can't roll of the bass on your headphone preamp or desk because that bass is going to bleed back into the mic.

So they are good for DJing but not much else. There are other isolation headphones on the market with a flatter frequency response in a similar price range like the AKG K271

Sennheiser HD25-1 II
I Recently bought these headphones for live sound to use instead of my Beyerdynamic DT770's. They are comfy on me and can easily cope with the high SPL's i need as i wear moulded earplugs after the first song. The sound is fairly well balanced, I am happy to eq and tweak signals even kick drums and basses confidently on these. They are also extremely robust and every part is replaceable.

Recording wise, I've been using them a lot whilst editing as they give me a really close-in, up-front sound. Clicks, pops, background noise and low end rumble are so easy to hear. I obviously prefer mixing on monitors, but we all have those times when we have to keep it down for our neighbours and partners. In this case i prefer a set of headphones with a bit more apparent space between the sound source and my eardum (like DT770's). But i really do enjoy the isolation and quality of the HD25's.

Excellent live sound headphones (and i presume DJ headphones given their massive following in that area!). Good mid priced studio headphones, really depends whether you like an up front sound or a pair with more space (I like both for different things).

Sennheiser HD25-1 II Headphones
One of the best headphones out there for the price. Affordable and perfect for both listening, due to good outside noise blocking, and good enough for rough mixing when away from monitors. They do not seem to boost or attenuate any frequencies too extremenly, aside from the fact that everything that comes out of them seems to have a crystal clear polish. All of it's parts are replaceable giving it a 10/10 for features. They are robust and comfortable and because they aren't huge like other headphones of this quality, therefor they look great too.

The headphone work incredibly well in noisy environments. They are punchy and get you focusing on the midrange sound very quickly. They are punchy too.
They are not good for you if isolation is a problem. You will be in your own little world with these cans.

Sennheiser HD25 II
If you don't want to read the whole thing, skip to the bottom for pros and cons and a short summary.

Now here on GS, most prefer the revered Audio-Technica ATH-M50's for headphone duties, but you may want to consider the HD-25' before ordering your next pair.

After owning a pair of these for a number of years, and I can safely say these are my favorite headphones I have ever owned. Many people swear by these, and many others shun them. Lets dive right in and find out why.

Using/Wearing them (comfort):

Many people really like the design of the HD-25 ii, and I am in that camp. The on ear design, rather than an over ear design, creates a seal on your ear, which provides excellent isolation, making these one of the industry standards for tracking. The split headband keeps the cans from flying off when you're jamming like an animal in the studio, and they are surprisingly lightweight. They also come with a set of velour ear cushions, which make these very comfortable for when you don't need quite as much isolation.

They clamp a little tight though for those with a larger head, which may cause a little discomfort after a couple hours. Some find these to accentuate sibilance, which can be a cause of ear fatigue and discomfort, but I have personally never experienced this.


Like I mentioned earlier, these headphones have a great split headband to keep these things locked on. They have an extra set of special cushions, and are very lightweight. But one very unique feature is that every part of this headphone is user replaceable. For example, if a driver tears or blows in one cup, you can order a new one, and just pop it right on. Although these are made of plastic, they are very robust, and can withstand years of being thrown around.

Some complaints for some are that the cable is a little bit on the short side. I find this to be true in the studio when tracking sometimes, but if you are using these with your iPhone in your pocket, jamming out to your tunes, as I often am, I find the chord to be a very comfortable length.

SOUND (the important part):

So, are these headphones only good for DJing? Are they accurate? Could I do a rough mix with a pair?

I'll answer the first question by saying these are the industry standard for DJ's, and as a result, many producers and engineers shy away from them, thinking they are too bass heavy or coloured. This is NOT true, and it is not the reason why DJ's love them.

People love these because they PUNCHY. The transient response on these puppy's is really fast and accurate. Drums come to life, and Bass parts are groovy with the tight low end these things have. The Top end is very present, but not overwhelming, and it maintains a fun and punchy characteristic. These are definitely a lively pair of headphones.

As for the frequency response, these are fairly "flat", even though no headphone, or even our ears for that matter are "flat". To be honest, the Bass and highs seem to be very slightly more present than the more neutral sounding mids, but they in no way feel boosted or coloured. I mix plenty of tracks when I'm traveling with these headphones, and when I come home to my monitors in the studio, the translation is actually pretty good.

But these aren't flawless. Where These don't shine as much as their competitors is in the stereo imaging. It isn't bad by any means, but it does seem a little, for lack of a better word, small. They are very close and in your face sounding. because of this, they don't give you that 3D effect your monitor speakers will give you, or that open back headphones will. As a result, these headphones sound a little less 'high-fidelity'.


Compared to its competitors (M50), these headphones are punchier, more fun, and more likely to put a smile on your face. The transient response is tight, and the frequency response is fairly neutral. The unique headband and lightweight design make these go-to live/traveling pair of headphones, but the on ear design and tight clamping force may cause discomfort to some. The lack of a authentic sounding stereo image may turn some off to these headphones, but some may embrace their more "in your face characteristics". All in all, I've grown to really love my HD-25's, and when my current pair grow old and die, I'm going straight back to the store for another pair, or maybe I'll just buy the replacement parts ;)


- Fun and punchy sound
- Tight transient response
- lightweight
- Won't fall of your head
- Durable, also has user replaceable parts.
- I think they look cool :D


- May be uncomfortable due to some tight clamping force and on ear design
- A little expensive for some, at $250 US
- Some feel these are a little too "in your face" sounding
- some think these look a little boring, or even cheap

thanks for reading my review.
