Question: Help me choose.... What's the main difference between these and the HD428 model?Can anyone recommend one of the two (428 vs 448) over the other?Thanks!
Document: I would recommend these headphones to anyone. I found them to be a great upgrade from the standard junk headphones that iPods provide. It could be the best one hundred dollars I have ever spent. They are extremely comfortable and have excellent sound quality. It is hard to find any fault with these headphones. The only possible negative is the bulkness of the headphones. They are large and you are unable to fold or make them more compact in any possible way.
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.
Isolation is all right. I would not recommend these to anyone.
I've been using this headphone extensively for about a month for music listening on a PC. I'm very happy with the results so far. Before I write anything else though, you should know that I also got thePanasonic RP-HT21 Lightweight Headphones with XBS Portfor $5 bucks, which is highly rated and the best entry-level headphone you can get for $5. Comparing the two, the main advantages of this $100 Sennheiser are noise cancellation and comfort.
However, those headphones are very tight on your ears, and become uncomfortable to wear after about 45 minutes to an hour. They also look really lame on your head, bulky and squared off in the center. I don't need any help making my head look any bigger and the HD-280 succeeded in doing so.The HD-448 is comfortable after many hours of wearing them, and looks sexy to boot.
Simply put, the HD448s are a great set of headphones that I would recommend to anyone who's looking to get more from their music, whether they're a listener or a performer.
I would recommend these to anyone looking for quality sound from their players, or pc's. Even with portables such as the DS or PSP they sound great. I won't be upgrading for quite some time as long as I have these baby's.
And because these are closed headphones, they do a good job of keeping out traffic sound (look both ways!) and other undesirable (non-music) sounds. I think these would be a potent set of headphones for anyone planning to use on public transportation or travel.I couldn't be happier with the HD448 given the price and would recommend them to anyone looking for a great value in headphones. Chances are, they are probably the ones you should be buying too.
Though the bass may be somewhat lacking, the overall quality of sound is amazing. As I have had other 10-30$ Sennheiser headphones break on me within a year I waited to write a review on these headphones. More than two years and counting of using these headphones the sound is as great as ever and I've had zero problems with them. I highly recommend them.
when I just got this headphone, I try it for about two hours, I think it is just a very regular product, the middle and high end is of for normal require. the low end it not good enough. so this product only can be use with classical and blue music. for rock is not enough.but after one or two weeks use. this headphone low end frequecy come better and better. I am very happy to get this headphone with this price.
Answer: I own a pair of 448 and my brother owns a 428.  I don't think the difference is 'too' noticable.  448's sound is more well rounded where as 428's sound is more bass heavy.  You will also notice that 428's wire is thinner.  Though I dislike the cushioning for both as it is too hot.
