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!
