This review is from: Sennheiser HD448 Closed Circumaural Hi-Fi Headphone
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....

I bought these headphones to replace a pair of old Pioneer headphones that I inherited from my family. I wanted something better than earbuds to listen to when I was creating music. I also live in an apartment, and since the walls aren't that thick, with cheap headphones, I can sometimes hear outside noise (like the TV from the front room). I chose a pair of closed headphones to hopefully mitigate some of this noise.
Pros:
*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.
Cons:
*I can't think of any downsides, I'm absolutely thrilled with my purchase.
Summary:
A wonderful pair of closed headphones made by one of the premier manufacturers of headphones. You absolutely can't go wrong with these....

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...
