In general, the sound of the Sennheiser HD448 is excellent. The levels have mellowed out some with use, but still keep a small harshness to the sound, but not to the point of distraction when listening to music. The bass is tight for headphones in this price bracket and you do not ever find that they are lacking bass. The sound is satisfying, even for long sessions and you don’t find yourself suffering from listening exhaustion with the Sennheiser HD448 frequently. These cans are becoming a sanctuary for this touring musician. Each of the components are there for reproducing recorded music superbly. Slip them on and the outside sounds slightly go away. Put on the music and the outside noises and distractions are gone, leaving only you and your tunes. The music sounds tight throughout the spectrum. You can use these cans both with and without an amplifier. If you use with an amp, it improves the volume and some key frequencies. The iPod volume has to be pretty near to %90 to have a healthy listening level without the amp. Obviously, the original volume level of the MP4 offers quite a bit to do with the output volume of the iPod. In comparison to the PXC350, the Sennheiser HD448 really blocks much more noise passively; however once you put some batteries and turn on the active cancelling of the PXC350 it much surpasses the HD448, but thats rather obvious. With no batteries however, the HD448 blocks more noise.

Costumer Reviews
I bought these headphones after returning the Bose Triports Bose® around-ear headphones, for personal and portable listening, which have good sound but are flimsy. Even out of the box, without time for break-in, they are stunning. The sound is precise, clear, and natural. Listening to Mozart's Clarinet Quintet, I hear each instrument beautifully and in surprising detail.
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.
These cans have become a sanctuary for this touring musician... All of the elements are there for reproducing recorded music superbly. Slip them on and the outside noises slightly go away. Put on the music and the outside noises and distractions are gone, leaving only you and your tunes. The music sounds tight throughout the spectrum. I have used these cans both with and without an amp (the Fii0 3) and I prefer the amp since it boosts the volume and some key frequencies. The iPod volume has to be pretty close to %90 to have a healthy listening level without the amp. Of course, the original volume level of the MP4 has a lot to do with the output volume of the iPod.
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!
