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.
Summary: Based on all the past reviews, I was expecting some pretty awesome headphones. I guess I had set my expectations too high. I'm not an audiophile, but I didn't really sense a superior sound quality from these cans as compared with lower priced Sennheisers. They sounded better, but I don't know if they sounded $50 better. The thing I really can't stand about these headphones is that they put an extreme amount of pressure on your head.
Summary: I am basing my review with the Tack Mod. The Tack Mod helped increase the bass impact and extension. These headphones have slight echo. Very analytical and not so warm. These also have the highest isolation i know of for full size headphones because it has the highest clamping force.
Summary: I've had the HD-280's for about a year now. I will get straight to the point. Pros: `one of the best sub 100 closed headphones out there `decent treble and punchy bass `dynamic frequency spectrum `clear highs `great for sound monitoring `noise isolation about 10dbs `user replaceable parts Cons: `plastic headband might start cracking after heavy usage `big and heavy, not too portable `these phones are not musical `music sounds tinned out at some high frequency levels...
Summary: The headphone itself is well constructed and projects quality as well as sturdiness. Since it is a closed-in headset, it is a nice way to block out the outside world and be in your own world when enjoying your music. As far as sound is concerned, I'm a little disappointed because of the lack of bass and clarity of the highs.
Summary: After the headband broke on my Bose Triport AE headphones for the 2nd time (pre 2005 model), I opted for the HD280 headphones. The first thing I had to adjust to was the sheer weight and bulkiness of the HD280's. However this is often the case for headphones dubbed 'DJ' headphones. Unlike my HD25-1's the sound was generally a touch thin. It was good and detailed, but as a bass lover, they left me wanting.
