Differences between the old and new outlined below.

Specifications

Summary

Putting on the HD 25’s was like someone took a veil off of the music, allowing it to finally breathe a little and expose what’s going on. The sound that the 25’s give off is just astounding at times. There are so much clarity and detail; I started hearing subtle things that I hadn’t noticed before with other headphones. Stuff like the echoes in the background, faint noises, instrument sounds that I missed, guitar plucks, and that sound that your fingers make when you change chords. It’s really a treat to be able to hear the music in all its rawness.

Keep in mind that these babies aren’t always going to sound fabulous. Because they are so aggressive, they have a tendency to become very fatiguing after awhile. I was finding myself taking frequent breaks because the listening sessions are so intense. They are comfortable at first, but again, you will find yourself taking them off every so often for a break.

They are also light as a feather, but as durable as people say. I can’t imagine these breaking any time soon.

Overall, the sound can be described as crispy like Rice Krispies. Lol. It’s definitely pronounced and forward in the mid-range, which can lead to some sibilance depending on the song and quality of the said song. What does Sibilant mean? It’s the type of headphones you can put on and immediately enjoy. So strap your seat belt on folks! 😛

Pros

  • Lively sound. Extremely engaging.
  • Treble and mid-range detail are excellent.
  • Bass is downright impressive. It’s not in your face, but also not lost. It’s got a nice texture and articulation that put a huge smile on my face. 🙂 I would say with some caution that these are a bass-heads type of can.
  • Good imaging and Soundstage.
  • Light and durable as heck. Expect to use and abuse these with no sign of wear.
  • Aggressive, fun sound.
  • Noise isolation is phenomenal. These will block out the majority of the sound. You won’t be able to hear a normal conversation or much of anything else.
  • Portable. Just toss them in your pack and away you go. These aren’t the type of headphones I would be worried about breaking.

Cons

  • Lack of accessories. They came with a 1/4″ adapter and that was it. Would have been nice to have a carry case and some replacement ear pads.
  • Not exactly the most comfortable headphones around.

Amp/DAC requirements

These don’t really require an amp to sound good, but I’m sure they really start to open up with one. What is headphone impedance?

Who these headphones benefit?

Does well with:

  • Rap &Hip/Hop
  • EDM
  • DJ’s
  • Movies

Still good, but not the best:

  • Jazz
  • Classical
  • Pop
  • Rock/Metal
  • Indie

I like them with these genres, but they really do shine with more bass-emphasized music.

Thoughts from Stu’s notepad

  • The Soundstage is very good for a closed-back model. Just don’t expect to be blown away or anything. The imaging and instrument placement is also pretty stellar. You’ll be able to discern where sounds are coming from fairly easily. What is Soundstage?
  • The left ear-cup rotates back and forth for DJs in a live setting. Also works pretty well if someone is blabbing and you feel like listening to what they have to say. 😀
  • In my research, many people complained about the short cable. I really happen to enjoy it because I’m so used to cables that are a hundred feet long. It’s a welcome change for me, but if you’re using these in a DJ/live setting, I could see how this would be an issue.
  • Remember that there are a ton of different versions of the HD25. However, the only one you should really concern yourself with is the one I’m reviewing today.
  • These sound really good from most portable devices, but they don’t sound that great coming straight out of my laptop. Something to keep in mind.

For clarity’s sake:

The Many Faces.

  1. HD 25 Professional (New model). The one being reviewed today.
  2. HD 25 Light. Doesn’t have the double head-bands.
  3. HD 25 Plus. Comes with a straight and coiled cable. I honestly don’t see why they can’t include that in the regular version, but whatever lol.
  4. HD 25-1 II – 70 Ohm impedance; 1.5-meter cable with right-angle miniplug.
  5. adidas Original – Like above, but with Adidas color scheme.
  6. HD 25-II – 70 Ohm impedance with two-meter cable and straight connector. These are no longer available.
  7. HD 25-C II – 70 Ohm impedance with a three-meter coiled cable and straight plug.
  8. HD 25-13 II – 600 Ohm impedance with three-meter cable and straight connector.
  9. HD 25-SP II – The cheap version of the HD 25, no split headband; 85 Ohm impedance; different driver. This is the one that sounds different and is not recommended.

So basically, don’t bother with the old models. Vendors are trying to sell them for a ridiculous amount. The new model (named HD 25 Professional), is a lot less, and you’re still getting that same great sound from the previous versions. In fact, overall the signature of this headphone has remained unchanged since 1987, with a few exceptions that are noted above.

Consensus/Conclusion

A sound that blows many other headphones in this price range out of the water. Built to last like Duralast. Engaging sound though can be very fatiguing after awhile. Comfortable at first, but you will need somewhat frequent rest periods. Aggressive, in-your-face sound that reveals a lot about the music. Can be picky about source material. Make sure you’re listening to a good recording! 320 kbps should be sought after here.

Final Word

I love the clarity and crisp detail that the HD25’s provide. They really do most everything right, and I haven’t been this excited about a pair of headphones since I purchased the M50’s in early 2013.

It’s definitely a sound that will initially excite the snot out of you. It’s aggressive, dense, and provides an incredible amount of detail. The headphones themselves are extremely durable, but as far as the comfort and intensity of the sound go, you may find yourself taking a break every so often.

Overall I can’t recommend them enough. The fact that all the parts are replaceable and they have stood the test of time makes them a pretty easy choice.

 


Well, that’s about it for today my friend! I hope you’ve enjoyed this Sennheiser HD 25 Review.

Hi Stuar, I have read almost all of your reviews and I really like your honesty. I need your help to be able to choose wisely. I am looking for closed headphones and I really like this hd 25 model. i want a headset with lots of detail and clarity for under $ 200 and i have seen other models like the akg 553 and dt 770. You who have had the opportunity to listen to the 3 models which you think have a more revealing sound full of details and if the difference is minimal with the other models. If the difference between the 3 models is minimal, I will buy the most economical one. I listen to classic rock and vocal jazz and jazz fusion

Hey man! Thank you for the love! Yeah the HD25 hands down lol. The other 2 are good, but if you’re looking for loads of detail and clarity, the HD25 is probably the best of those 3 even though I love the K553 and 770. 770 is more for bass heads due to it’s V-shape. The K553 is probably my second choice behind the HD25. It sounds super open with a great Soundstage.

If you like a more neutral sort of detailed sound, I would say go with the 553. But the HD25 is super lively, intense, and exciting. It’s almost like doing cocaine or something (not that I know anything about that heheheheh). No really I don’t. Haha. But it’s super in your face and makes you want to bang your head. It’s my go to headphone for metal actually.

What kind of Classic Rock and jazz fusion are you into? I really like both of those genres a lot. If you listen to Plini, Chon, Animals as leaders, or anything similar (Prog/Jazz fusion), I would go ahead and hit purchase on the HD25 like now. Lol. It really is a match made in heaven. Plus they’re the most rugged durable headphones I’ve ever owned.

What do you think?

Hey man thanks for your reply !! The hd 25s are my favorites of that group, I listen to rock music from The Beatles / Genesis / Metallica / Ozzy Osbourne / Pink Floyd / Rush / Black Sabbath / Muse Radiohead etc and jazz fusion Djabe / Yazz ahmed / Bob Holz / Jon Hassell and listen Also jazz vocal Dianna Krall / Rebbeca Pidgeon. As I said before I look for a high resolution (listen to details and nuances in the music hidden with a good separation of instruments). A few years ago I was perplexed when a friend played Across The universe of the beatles (Past Masters version, Volume Two) and I could hear at the beginning of the song all the sounds of nature, man that song had been heard at least 50 times but never I had heard all those sounds that I could hear in your hifi sound system, basically that is what I look for in the headphones for those details sounds that a normal system cannot bring to light, I am looking for a headset that does. and durability is necessary because I had to make many sacrifices to be able to collect 150 $ hahaha and it would be very painful if they break in 2 years.In summary I am looking for great clarity and details to be able to get all the hidden information of a song and make it durable, I think the hd 25 meets the requirements. I like the akg k553 a lot but recently the akg k371 came out which seems to be the same akg k553 but without that great soundstage and is worth 150 although the k553 is better built and has better soundstage. but yes the hd 25 can provide me with what I am looking for in a satisfactory way that will be the one that I will buy

Hey man! Did you decide on the HD25? Need some more guidance? Let me know! I know that feeling all too well of hearing things you never noticed in songs before. That just recently happened to me with the HIFIMAN DEVA playing Aphex Twin’s “Windowlicker”, a song I’ve been listening to since 2005. Can you believe that? I heard something towards the end that I’ve never heard in all my life, and I was just flabbergasted when it came through the headphones. You can imagine how many times I’ve heard the song over a 15 year period, and how shocked I was. I know you kind of wanted a closed back though and the wired DEVA is a tad outside of budget at around $219. Even so, if you could stretch just a bit, or even get something like a HIFIMAN 2020 Revison 400i for right at budget (around $169 – price subject to change), I think that or the HD25 is still the way to go. The 400i is going to be more open sounding for you.

Hi Stu. I live in a country with a deep economic crisis (Venezuela) and buying a headphone for the vast majority is a luxury they cannot afford. If I buy I will not be able to return it if I do not like it. that’s why I want to be sure of what I’m going to buy. what I need is good sound quality along with good durability. I want a clean sound where I can hear a chorus of a beatles song and be able to listen to each voice separately to give an example. clarity and detail along with good durability. if it is a closed headset even better but it is not strictly necessary. my budget is 150-170 dollars. so far my options are senn hd 25/ beyer dt 770/ ath m50x and in the open ones senn hd 559 /senn hd 599/ senn 58X/ grade sr80e and fidelio x2. I really like the hd 25 for its design and durability and price but I don’t know how clear and detailed it will be compared to the hd 599, the ath m50x or the fidelio x2. I am looking for the best high resolution sound that I can buy with that budget (approximately 150) and that guarantees durability and that I can use directly from my smartphone.

Hey man! Just replied to your other comment. Are you still considering the others outside of the HD25, DT770, and K553? Gosh considering your criteria: High res sound, around $150, and guaranteed durability while being able to play from a smartphone? That’s HD25 all the way.

Let me know though about the others and if you’re still considering them.

The DT 1350s are great to compare with these. Unfortunately Beyer doesn’t make them anymore. Not sure how the Aventhos compare, but I thought their other portable, the T51i, didn’t sound the same (like a monitor), but was voiced for pop music. The 1350s are more refined and beautiful sounding and higher quality, I think, except with two pairs of mine that I bought through eBay the driver would end up dying (maybe I was listening too loud?) and that hasn’t happened yet with my HD 25s. So some German headphones are “built like a tank” but it might be the all plastic ones rather than the metal ones (Beyer), weirdly enough. Or I just didn’t luck out. Anyway if you ever come across them be sure to take a listen, if they have the facelift pads (that are a bit bigger than the original, the ones that mushroom out a bit from the edges of the cups). Those seal better on the ear. It has really great bass that extends perfectly down flat like a planar magnetic. Maybe it is a little dark and mellow sounding compared to the Sennheiser which is more upfront and lively and drier sounding (less colored?)

Hey Matthew! Thanks for the great comment. I had always wanted to do a head to head between those 2 headphones but never got the chance. It’s unfortunate they don’t make them anymore. The HD25 is seriously one of the most intense and headbanging good times I’ve ever had with a product. It’s definitely my go-to metal headphone. I would like to get another one at some point (long story lol). You’re def right about the HD25 (upfront and lively is right on). People used to really rave about the 1350 IIRC.
