For the last 25 years at least I have been using Sennheiser headphones.
I currently have 5 pairs that I use very frequently but the newest ones are the ones you want to know about.
I had been using a pair of Sennheiser HD280 Pro [64 Ohm] and I was very happy with them and then early this year I heard about the "upgrade" to these, the HD 380 Pro and being a bit of a sound nerd I had to have some.
Was it worth it? Well, yes it was!
They are slightly lighter, they fold better and come with their own case, they have a curly lead rather than the straight one for the 280s and they are even more comfortable for long time listening!
But what you really want to know about is the sound quality - they are better in all respects . . . the sound is great!
The bass is tight with a crisp attack but it does go quite deep and sounds really good.
The midrange is musical, well controlled with a good soundstage - the instruments are well placed.
The treble is tight, high without being shrill and hangs onto the top notes say of cymbals without becoming papery and thin.
The sound altogether is musical, well controlled and not coloured - if you want deep booming bass and greatly coloured sound then these are not for you.
All told, these for me are superb headphones and I am delighted to have made their acquaintance.
Oh yes . . . and I also use them with my iPod and that sounds even better too . . .
I give them 5 stars for sound and 5 stars for comfort.
