The Sennheiser HD 280 pro studio headphones are designed for professional audio engineers and musicians seeking high-quality, neutral sound monitoring. Featuring a closed-back, circumaural design, these headphones block up to 32dB of outside noise, allowing you to focus on the details of your mix.

I would specifically describe the sound as clear. A quick check of the frequency chart included in the manual suggests slight dips in the mid bass and at about 3 - 5 Khz, and listening confirms this.

I'm not an experienced headphone enthusiast so there could be better product for similar $$ but I would think any difference would be spiting hairs sound wise or preferences I like the Senns sound anyway .

Good bass decent highs and mids (if you like the Senns sound ) they have good vocal and percussion pop .I like them much better than my KRK KNS 8400

None for the $99.00 or a little more here

I don't actually know the model year, but these phones have been around for about 10 years according to HeadRoom. I got mine about 3 years ago or so. I picked them out based on the data at HeadRoom, since there are not many good headphones sold locally.

Sennheiser's HD 280s are a perennial favorite among budget-minded audiophiles. And listening to their balanced, flat tonal presentation you can see why. If there's any hint of coloration (anywhere), I certainly couldn't find it. That's great if you happen to be mixing an album.

"...much deliberation I chose the Sennheiser HD280 pro closed monitoring headphones at just under a hundred pounds which are essentially pro spec cans designed for studio use. I'm not going to copy the full spec of the headphones as I suspect that it would be double dutch to most people but should...

Faithful sound reproduction; no sound leakage; comfortable

None

I've been using these headphones since Mar. of 2009 and have been pretty content ever since. I mean, sure, higher-end headphones do exist, but usually they're way more expensive and designed for content that isn't as accessible as MP3s and such.

I use these headphones with my Yaesu FT-920 and they are clear with some "over ears" base sound, but not to much so. They are still crisp and clear sounding. AM, SSB and CW come through equally well. They will keep the noise out.

the HD 280 pro deliver a tight sound wih a flat frequency responce. Theu don't seem to colour the sound in any way. And deliver a true representation on the source audio.

These are excellent headphones, offering a premium quality full spectrum of sound (great highs, mids, and lows) as well as sealing your music in and peripheral noise out. The ear pieces fold flat so you can easily transport them in a case with other things or by themselves.
