Excerpt: Really a rating of 3.5 stars. Sound is crisp enough for professional work. They are a bit heavier than the Sennheiser 202 that they replaced. Hopefully they will last longer, since the S202's break easily.
Summary: The 280 pro as a great value headphone, but it does have a few problems. First, the bass extends very low, but it's not very strong - it does respond well to equalisation though. Second, the highs can be a bit harsh/grating - the highs extend very high. Third, the headband tends to crack/break after a while of use. Despite these flaws it's still an excellent entry level audiophile headphone. Also consider the Sony V6.
Summary: Extreme clamping force, very poor quality earpads, suckout in upper bass and lower mids (requires several minutes to seal to get better bass and mids and reduce hollow sound), and a bit too much highs around 7 and 9 khz making a slight zingy sound. If you can tolerate these for a few minutes until they begin to seal to your head, the sound will be fairly good hi-fi for the current price around $99 USD.
Excerpt: I used these for a few months. First, the sound quality is pretty decent for a closed headphone. There are certainly better sounding headphones out there for less money, but these have a good enough sound quality to price ratio that I can recommend them. The actual build quality is not awful, but it's not up to the standards as some of Sennheiser's other headphones are at, which is to be expected given the huge price disparity. Finally, the clamp.
Summary: They can become uncomfortable. You can't wear them for too long as they start to hurt from squeezing your head (on any setting). They have good bass reference, mids are ok, and highs are not too bright or harsh. They pretty much cover the whole ear and from the tight squeeze--they block out a lot of ambiance.
Excerpt: I used these headphones for 3 years for production sound mixing and some studio recording. The construction is great, the ear pads are replaceable, decent mid-range which is good for capturing dialogue when mixing on location, great noise isolation as well, they are also somewhat comfortable.
Summary: These headphones are much better & cheaper than the Bose AE2 model. But when it comes to listening to good music comfort is also very important. I have had these 280's for about 2 weeks now & the sound lives up to my expectation as a audiophile teamed up with a headphone amp, but its just not comfortable. These feel like a clamp around my head & puts a lot of pressure to the point i cant wear it over 10-15 minutes or I start to get a headache due to the pressure.
Summary: I have a hearing loss; therefore, I depend on phones when watching tv. the phones met my expectations for the price, but they lack the comfort and the noise reduction of the Bose phones that I also use for tv viewing.
Excerpt: I purchased these phones a couple years ago because of the brand reputation and thinking that they would last me a *long* time. The good news: the sound quality is fantastic. I hear details and definition I've never hear before in some of my music. The bad news: after a year+ of heavy use while recording voiceovers, the foam padding on one of the headphones has already detached and now is about half way unglued. I expected something a lot more durable than this.
