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...

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...

Legend ENG lives on

Posted

Pros: accurate, very good imaging, portable, replaceable parts

Cons: comfort for others

The HD 25 series has been around for 15 years and this has been my 2nd purchase of the famed dual-band headphone.     Value: 10 years ago, if you are purchasing a $200 headphone it would've sounded absurd. Thanks to Beats by Dre, $200 headphones are now a steal. For $200, you get 2 pairs of ear pads (1) velour and (1) synthetic, also you get a nylon carrying bag, and of course the star of the show, the HD 25-1 II.   Audio Quality: HD25s are a favorite among DJs and broadcasters, although it is primarily designed for studio use, I rarely see this headphone used for mixing and remastering. The most common headphone, I see in studios are the ATH-M50 and...

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...

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...

Amazing headphones, but you already know that

Posted

Pros: Sound quality, Confort, Isolation

Cons: none so far

No introduction is needed for this pair. The "rumours" about the sound quality are true. Some people disagree that they are good for music production, but I am not using them for this reason, so I cannot comment on that. When I am listening to music I prefer it to come to my ears as the musicians and sound engineers intended to, and I think that these headphones are doing it to a great extent.   Some people also find them to be uncomfortable. Well, they are not as comfortable as HD 598 for example, but this is to be expected from a closed-back pair. I would not expect more comfort than what they give. I'd describe my head as medium size, so people with large heads may find them a...

Very Good But Not Perfect

Posted

Pros: Versatile, Lightweight, Solid Exciting Sound, Great For DJs & Exercise

Cons: Not Good For Mixing, Not For The Fashion Conscious, Intermittent Audio Issue, Expensive Replacement Parts, Low Volume On Portable Audio Devices

I've owned 2 pairs of these headphones over the past 10 years so feel I've gotten to know them pretty well. Apart from the cheaper SP version these are the only decent headphones above a budget level that I've really tried.   Looks   I don't think this headphone is for the fashion conscious but they do have a cool look of its own in an industry standard geeky DJ kind of a way.   Durability   This is a mixed bag for me although maybe it is harsh to complain about a pair of headphones that last so long. Overall they are pretty indestructible and I regularly take them to the gym and put them in there and take them everywhere without a second thought. You don't...

Classic

Posted

Pros: Solid audio performance; good imaging and details; tight and fun sound; excellent isolation; durability; user replaceable parts; value for money

Cons: Soundstage

Design/durability: They look professional. As for the build quality, these are certainly the most rugged headphones on the market. It is practically indestructible, and if a part comes to break it is possible just to replace the part itself (ear pads, cable, headband, you name it). They can be thrown in a bag and not be worried about. Designed to last a long time, if not a lifetime. Fit/comfort: Average. Many complain about the clamping force of the HD25, but I find it to be okay after a few months using them. The headband becomes more loose and flexible, although it still has more pressure than on other headphones. Definitely not the most comfortable cans around, though....

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...
