Summary: What a step up from the 280's. The sound is clear, good bass response, the case is great (I've been traveling extensively for the last 2 months with the headphones) The highs are only a couple dB low, but everything else sounds fantastic.
Pros: Sound is awesome, better than any previous pair of headphones I have previously used but I also never purchased a $200 set before. Bass is outstanding and the clarity is unreal. I only use the headphones for casual listening (mostly classic rock, blues, 50's) and it is now an entirely different experience. I am hearing things I never knew existed. Sound quality easily earns five + eggs.
Cons: These headphones are not uncomfortable but are not as comfortable as I would have liked them to be. I prefer headphones with a soft feel that makes it easy to forget they are on. The HD380's have a somewhat harsh feel to them and, as a result, I am constantly aware I have them on. I took one egg off because of this although the sound is so good I have no regrets having decided to purchase them.
Summary: For their size, these headphones are real comfortable. They fold into a small pouch. They sound real crisp. I picked these up for home studio application. The only problem is: they sound way too heavy on the bass. And that can be very misleading for the mixdowns.
Summary: I upgraded from the HD 280 to the HD HD 380 and I'm very pleased. I compared these to Dre/Monster and Bose and believe the Sennheisers provide a better overall value relative to sound quality, style and price. I would not hesitate to pull the trigger on these.
Summary: This was recommended to me by a friend and because of the other great reviews on the web I purchased a pair. What I can say is that it really brings out the details in music. Those low bit rate MP3's will not sound too good now. Bass is not exaggerated and highs are nice and smooth. The quality of the DAC is very important for this set of cans.
Pros: Good amount of detail and also great passive noise isolation.
Cons: They will not sound good unless you use high quality sources. Minor coloration.
Summary: Very clear sound and linear. Base is under control and well defined but not laking. The source is important as I found that if used without a proper amp the sound stage was impacted greatly also with some clarity in some instances depending on the source I got distorted mid & highs (i.e.
Pros: Better than expected sound, good value, sound stage very noticeable when amped.
Cons: Design could be better, annoying cord, uncomfortable in warm wether.
Summary: I'd been looking for headphones for my iPad and computer to listen to music and wanted a quality set this time so as to get the best out smething I enjoy. Prior to buying these I reviewed a lot of product on line cross comparing most leading brands including Bose, and AKG. In the end for this price range the Sennheiser HD 380 pro won out against Bose. Bose were very light and the most comfortable I'd ever worn but even they weren't up to the audio standard of these.
