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’s so much clarity and detail; I started hearing subtle things that I hadn’t noticed before with other headphones. Stuff like the echos 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 it’s 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, 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 in the treble area, which can lead to some sibilance depending on the song and quality of said song. What does Sibilant mean? It’s the type of headphone you can put on and immediately enjoy. So strap your seat belt on folks! 😛
- 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.
- Pretty comfy. Just be aware that you’ll have to take breaks.
- Aggressive, fun sound.
- Noise isolation is phenomenal. These will block out the majority of sound. You won’t be able to hear 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.
- 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.
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
Still good, but not the best:
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 DJ’s 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:
- HD 25 Professional (New model). The one being reviewed today.
- HD 25 Light. Doesn’t have the double head-bands.
- HD 25 Plus. Comes with straight and coiled cable. I honestly don’t see why they can’t include that in the regular version, but whatever lol.
- HD 25-1 II – 70 Ohm impedance; 1.5 meter cable with right-angle miniplug.
- adidas Original – Like above, but with adidas color scheme.
HD 25-II – 70 Ohm impedance with two meter cable and straight connector. These are no longer available.
- HD 25-C II – 70 Ohm impedance with three meter coiled cable and straight plug.
- HD 25-13 II – 600 Ohm impedance with three meter cable and straight connector.
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 remain unchanged since 1987, with a few exceptions that are noted above.
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, 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.
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 comfortable and durable, but 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.
