You can buy these with great confidence. An audiophile vendor not associated with Amazon gives these headphones 5/5, and that company has ears trained on equipment costing thousands of dollars. Of course, if you are prepared to buy Sennheiser HD 600 Sennheiser HD600 Over-Ear Open Dynamic Hi-Fi Professional Stereo Headphones (Black) or HD 650 Sennheiser HD650 Audiophile Open Dynamic Stereo Headphone, you will hear something else again, a magical liquidity - but only if you couple them with a dedicated headphone amplifier. If you use headphones to listen to music, rather than music to listen to headphones, you will be very happy with the 448 for portables and home listening.
PS: It's a year since I posted this review, and I have just made a surprising discovery (surprising to me, at any rate). I knew these were good headphones without an amplifier. What I did not realize is that with a headphone amplifier, they are in another league. I have a small headphone amplifier, and I was getting only fair results with my high impedance headphones (which are outstanding on my other, larger amplifier). So just as an experiment, when frankly I was ready to buy a better amplifier, I asked myself what would happen if I took out the Sennheiser HD 530 (300 ohm impedance) and tried the HD 448. They're stunning. I thought it wouldn't be necessary, because the HD 448 has just a 32 ohm impedance. And it isn't necessary, but it certainly makes a huge difference. Put the HD 448 together with -- say -- a Headroom Airhead or Bithead and you have an excellent little rig.
*Amazing sound quality! When I first started listening to my music in these headphones, I started hearing instruments and riffs that I had never noticed before. I don't know how much of that is the placebo effect, but it's amazing.
*When you put them on and you don't have any audio coming in, you can hear what is going on around you, and they don't cancel a lot of noise, but as soon as you start playing music through them, all the outside noise goes away. I had several of my friends try them on and I talked to them at a normal volume, and every single one of them insisted that I wasn't really talking, just moving my lips. They are that good.
*Very comfortable. They fit nicely on my head, and even after wearing them for hours, they aren't uncomfortable in the slightest.
*They come with an extension cord and adapter for a larger plug style. I thought the short cord along with the longer extension was a nice touch, and adding the adapter was really nice also.
*I can't think of any downsides, I'm absolutely thrilled with my purchase.
A wonderful pair of closed headphones made by one of the premier manufacturers of headphones. You absolutely can't go wrong with these.
Right out of the box, they sound great great but are a little bright sounding. I have been burning them in for around 24 hours and they are mellowing quite nicely... m-e-l-l-o-w
To me, its heaven to lay down on my bunk and put these babys on and listen to my library in HI-FI while riding down the highway (then usually falling fast asleep with them on). That is another great point... you can lay on your back and sleep with these on since they are light weight and the pleather ear pad covers are friendly and comfortable. They also ship with an o.k. drawstring bag and a gold plated extension cord (great idea!)
My only complaint is that they seem a little fragile since they are constructed out of plastic and designed to be light weight (we all know what happens to plastic over time.) I would rather have had a longer lasting frame and more weight. If you sit on them, they are goners! And the cord is thin like a set of portable phone would have. Maybe they have to do this to keep the ohms low enough for an iPod to push the speakers? I think they were trying to keep a lot of the features of these cans similar to a portable while still being super hi-fi. They also look super sharp either on or off.
I guess I am not what some refer to as an audiophile (I don't know any audiophiles that prefer headphones unless they are traveling or DJing live) but I do make my living playing music and equally enjoy listening to it. These phones do color some frequencies, but all consumer audio gear does that. You would be crazy to want to listen to totally flat studio headphones or speakers for leisure, leave that to audio mastering engineers. These cans do not over emphasize the bass, which is great if you like a wide range of music, not just rap, etc. If you are into heavy bass, pick some cans that are geared for that. It personally drives me nuts when listening to boomy upright jazz bass. These cans don't do that!
Bottom line: I LOVE these!
And for $100 you can't loose!
I was looking for closed headphones that I could use while in bed without disturbing my wife. This was mostly for music, but also TV viewing late at night.
I am an audiophile who loves music and have a rather high-end system (separates) in another room. In general, I am not a headphone listener, and dislike many of the lower cost headphones I own or have owned. I listen to mostly uncompressed, CD quality or higher quality music. Mostly this consists of Jazz, acoustic, vocal, classical, world, etc. Not much rock/pop at all (nearly zero) I am sensitive to poorly integrated bass, have owned some sennheiser lower cost PX100, and although I could tolerate them for short periods, the bass constantly annoyed me. In general, I have often liked the delicate non-strident high-end of most Sennheiser headsets through the years.
For this purpose, these phones plug into a low-end, low-cost Onkyo AV Receiver I use in the bedroom. I actually like the Onkyo, and feel its sound is musical, and not at all strident or difficult to listen to. Unfortunately, the Onkyo like most cheap AV receivers performs volume control in the digital domain, removing information/resolution from the signal as it gets softer. Yet, it remains musical at reasonable volumes, and surprisingly well resolved through these headphones.
I was shocked with the quality and well-balanced aspects of these headphones. For the money, I have a suspicion that this particular headphone in the Sennheiser lineup has probably the most balanced audiophile type sound for the least amount of money. Go lower, and many or most of these types of phones sound bloated geared towards ears that like the boom/tic sound. These maintain a nice top-bottom coherence, reasonably good bass definition, fantastic midrange detail and timbre accuracy, along with the familiar delicate high-end I like from most good Sennheisers. Definitely non-fatiguing.
They are nicely comfortable and appear relatively well made for the price. They are low-cost phones -- keep that in mind here.
Negative is they are clearly positioned down-market, towards portables, with the native 1/8" jack. I use the included 1/4" adapter and pair this with the long Grado extension cord to reach my listening position. The thinness of the captive cord is obvious, particularly in contrast with the robust Grado extension it is going into (highly recommended extension). The combination of the 1/4" adapter and thin native cord should be degrading the sound to some extent. However, they still do sound unexpectedly fantastic through this combination to the Onkyo receiver. Looking on the specs from Sennheiser, it appears the tiny thin cord is made from OFC, which probably helps despite its apparently frail thinness.
All in all, I am extremely happy with this purchase, and wanted to share a slightly different perspective on these musical headphones.
You can fix this by getting a headphone amplifier...
Now that my library is good I can say that the HD448 sound great but definitely not as I expected from a $100 Sennheiser headphones. The bass disappointed me, but the mids are really good, these headphones are definitely made for acoustic music and such.
These headphones are great for classical, instrumental music... seriously the acoustics and vocals sound incredible.
These headphones are extremely comfortable no matter the size/shape of your head although they can get a little warm after a while, but that happens with almost any closed-back circumaural headphones.
I wouldn't recommend these headphones if you listen to lots of electronic and metal music.
Good noise isolation
Reliable (been using them for months and still look/sound as new)
Minimal audio leak
Excellent for acoustics
Limited audio capabilities
For $100 I would recommend you try Audio-Technica ATH-M50, Denon D1001 (closed back) or Grado SR80i (open ear) first before you buy Sennheiser HD448.
