Still the total package

Posted

Pros: Indestructible, comfortable, well-isolating, great detail and clarity

Cons: Fairly analytical sound, treble can be aggressive and unnatural, small soundstage

The HD25-1 has been my favorite (trans)portable headphone for quite a few months. I spend a few nights a week away from my home rig and the HD25 works wonders with my iBasso D10 and netbook. Hi-fi on the go has never been so rugged and simple. Best of all is their sonic versatility – though my backup portables, the AKG K181Dj, excel with certain genres and recordings, the Sennheisers perform more than adequately with anything I can throw at them.Build Quality: When it comes to build quality, Sennheiser’s flagship portables can do no wrong. The structure of the HD25 is painfully elementary. They are neither flat-folding nor collapsible, with very simple rotating joints and removable...

Really good stuff

Posted

Pros: Small, lightweigt, solid, interchangable parts, easy to fall in love with.

Cons: minor cons. as in easy to look past, due to all the pros.

Being a non-professional, but a general music lover, My review will probably be in layman's terms, but why not. It will give the perspective from someone that observe music in a different way than the purely analytic fashion.   Once, I had a great home stereo consisting of NAD CD-player, amplifier and B&W speakers with some fancy cabling. -So I am not completely rookie regarding what sounds good and not. Neither am I a person that thinks that resonating boomboxes (cars) driving by is coolz because of lotz of basz. I like to hear all kinds of music. Anything from Mozart'ish music to music 'designed for serious PA-systems'.   Being without my stereo for the longest...

Plastic and pinching force is too much, squeeze my head and painful, Sound is ok

Posted

Pros: Light weight, portable

Cons: Hate plastic, uncomfortable, painful, not ergonomical , highs are too aggressive

Sennheiser HD25-II is one of hot model in on-ear headphone. I buy it because of high rating from different users. However, i feel very disappointed when I use it.   First of all, the headband structure is too tight. It makes my head painful and can't wear for more than 5 minutes, 1 song?!   Bass, quite strong   Mids - not natural   Highs - clear, but the highs are too aggressive. It hurts my ear when listening for long time.   I can't use it for more than 5 mins because of the headband pinching force. No matter how the sound is, the headphone is useless for a user if they can't use it daily.   Sorry about that. Sennheiser.

Too much bass, strident treble

Posted

Pros: Kinda of OK - there are much worse out there

Cons: Too much bass, treble is an assault upon my ears

Too much bass, strident treble. I guess it could be worse. Midrange is not bad. It might sound OK straight out of my out of my cheap Android phone which lacks power and sounds kind of muddy.   The treble hurts me. I wouldn't keep them though, even if someone gave them to me for free. I wouldn't give them to my kids either because I don't want to destroy their high frequency hearing.   Really ugly too.

Built to last the apocalypse

Posted

Pros: no headphone hair, in-your-face sound

Cons: exposed wires, clamping force

Seriously, these things are built to last. When the apocalypse occurs in 2012, this Sennheiser would be left intact (maybe the wires would get destroyed). And for future generations of the human race (or whoever takes over the earth), they would be a relic of the old world. I own two pairs, one for work and one for portable use, I treat the portable headphone with utmost care, like a baby, while the one for work gets tossed around and daily abuse, and yet both look the same. On a note of the clamping force, the frame needs to burn in, so that the force loosens and optimum comfort is achieved. Sound. How does it sound? It's a bit colored, I think. Definitely not neutral, but I've...

Excellent Cans for Home and Portable Use

Posted

Pros: Portable, outstanding sound quality, user-replaceable parts, rugged construction, great isolation and comfort

Cons: Slightly sibilant, closed-in soundstage

I have previously owned a lot of headphones, but I felt the need of an all-in-one solution that I could use at home or on-the-go. So I scoured and found that the Sennheiser HD25-1 II is the perfect headphone for my needs. It is a small, supra-aural pair of headphones with superb sound quality in its price range and category.   Construction: The HD25-1 is a very rugged set of cans. Although lightweight and looks flimsy, it actually holds well against constant abuse and wear. The split-headband design allows for both a secure and comfortable fit, perfect for lengthy listening sessions. The earcups themselves are made of hardened plastic, and do not easily scratch or dent when hit by an...

One of those closed back headphones everyone should at least try

Posted

Pros: Good all-around headphones with a smooth midrange (minus classical), fun to listen to. Great in trance/dubstep genre.

Cons: Prominent midbass can get in the way

My impressions is that these don’t sound significantly different than the cheaper SP version in terms of sound signature. The biggest difference is detail, more extended highs and smoother mid. If you didn’t like the SP version’s general sound you probably won’t like this either.   Comfort: I personally don't like on-ear headphones that much because of sweat and heat reasons and this is no exception. These will keep my ears reasonably warm on a rainy day. Takes a little fiddling around to get a good seal. My ear gets warm over half an hour. The clamping force is just right, not loose or vice grip.    Build: Everyone says these are built like a tank and I agree. These...

High quality headphones which are build to last.

Posted

Pros: Clear and detailed pure sound, solid build quality, light weight, decent isolation, serve a great purpose as DJ headphones

Cons: Neutral sound is not for everyone, narrow sound stage, clamping force takes time to soften up.

I'll make this clear - the sound signature of these headphones will not blow you away. I was expecting a lot from these (after reading the many positive reviews) and when i first listened to them i felt a little underwhelmed.   We've all had that experience where we listen to a piece of music and think...meh it's ok - and then months later you're putting in your top 10 all time favourite list. Well i've had the same experience with these cans. I have grown to love them!     Design - They're lightweight, surprisingly portable and have a minimal look and feel. They can be used as DJ headphones due to their tilt cup design (the left headphone can be tilted away from...

Durable great portable sound.

Posted

Pros: Detailed, portable, great isolation.

Cons: Not really confortable for long periods of time.

I have own the Sennheiser HD 25-1 II for more than 6 years now, and everything is still in perfect condition. I have always love the analytical sound this unit delivers... These have turn to be my personal favorite headphones for tracking live instruments and recording vocals, but I use them to listen to music when traveling, and they are my favorite portable headphones as well.   They are not really that confortable, I find them to be a little uneasy to wear for long periods of time, but they isolate really well and sound great with theire slightly v shaped sound signature. I will recomend this headphones for anyone looking to something portable and with great sound isolation.

Grand-daddy of Quality Closed Headphones

Posted

Pros: Neutral, detailed, non fatiguing, comfortable velour earpads, cable can be replaced with sennheiser HD650 cable

Cons: Not much soundstage

This is my reference for what a portable closed headphone should be. It's neutral and sounds good on all genres. It's not a giant killer like the DT531, but keep in mind it is closed and portable and has the most durable build quality of anything I've seen. Also, it has the cheapest, most cost effective upgrade available for it, the upgrade to an HD650 cable. In my opinion it is the second best deal to be had in headphones for a beginner to this hobby, second only to the Beyerdynamic DT531, if you can find it. The Beyerdynamic DT531 has better high range sparkle and soundstage, but less midrange realism, depending on the genre you're listening to. Anyways, neither are a perfect...

For DJs only

Posted

Pros: Very good isolation, reasonably dynamic

Cons: Painful on-ear clamping force, harsh treble peak, closed sound

These headphones are clearly designed for DJs in dance clubs and I can't recommend them for general or casual use.  They get 3 stars for doing what they're designed to do well enough but could be much better.   They are very isolating as a result of a strong clamping force that crushes my ears to the point of pain after 10-15 minutes.   The sound is very forward and punchy.  Good for techno/dance but lacks refinement, subtlety and space.   They are overly bright and there's a treble peak that causes sibilance and is very unattractive.  Though I didn't use a high quality amp this peak seems to be recognised in frequency response charts and other reviews...

Should be the Norm

Posted

Pros: balanced, isolated, easily repairable, neutral (a bit redundant, no?)

Cons: clamp force, looks and other aesthetics, accessibility

Summary: These headphones give an accurate picture of what the producers had in mind when they mixed their music because they have a well-balanced, present, but not over-powering bass.   Songs Used for Listening/Critiquing: Stuck on You - Michiko Unlike Any Other - Jeremy Ellis Garden - Totally Enormous Extinct Dinosaurs Basically, **** You - Deru Flashlight - Parliament Creator - Santigold Petrified - Fort Minor Jamba - Tyler, the Creator Ballad of NGB - Stateless I'll Never Leave You - Rogue Wave BloodStream - Quartet Session - Stateless Blue Ridge Mountains - Fleet Foxes Sunburn - Muse Rhino - Solander   I know that headphones are truly the best...

Buy these. Stop looking for any other headphones.

Posted

Pros: Amazing sound, split headband, rotatable cups, indestructible, crazy light.

Cons: Can be uncomfortable after an extremely long time wearing them, but still very comfortable.

Best headphones I have ever used. Ever. Period.  You will not use better headphones than these.  I directly compared these to Beats Studios the other day and the Beats almost made my eardrums bleed after using my good old Sennheisers.  OK, that was an exaggeration, but you get the point.
