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.

Hi, The 280 pro as a great value headphone, but it does have a few problems. First, the bass extends very low, but its not very strong, it does respond well to equalization though. Second, the highs can be a bit harsh/grating the highs extend very high.

Sennheiser's HD 280 model headphones come in three variants - the Pro, the Silver and the 13. The HD 280-Pro is the original design and is uniform in colour and has 64 Ohm impedance. The Silver is technically identical to the Pro but has a plastic silver-coloured back-plate on each phone.

Love the HD280 pros. Comfortable to wear even for long sessions. Sound is clean and detailed with rich lows and crisp highs but never harsh. Mid frequencies are well balanced. These are by far my favourites out of all the headphones I have tried in this price range.

The Sennheiser HD 280 Pro is a very good quality headset for the price. They do a very good job blocking outside noise and they also keep from leaking sound. The adjustable and rotative cups make them flexible and easy to store away.

Reliability

Human hearing range is about 20hz to 20Khz. The fact that it's range goes down to 8 and up to 25 will not be noticeable to most. Clarity of audio quality is limited by both the output source and the audio signal.

They are very comfortable for headphones, not to mention they have very nice sound quality; The coiled cord can prevent that loud noise that happens when something bumps the cord, as well as preventing it form getting tangled.

Much higher price than standard headphones; A bit bulky, wouldn't rely be able to take them out anywhere; (They're a bit expensive to be taking outside anyway) When compared to a 5 dollar set of headphones playing a compressed recording, the difference is not very notable compared to the price...

The Sennheiser HD 280 Pro, a $99.95 (direct) headphone pair designed for professional studio use, was released in 2003, before I began writing for PCMag. However, I often use it as something of a standard to A-B test similar types of pairs with, so it seemed appropriate to give a proper full-length...

Accurate, clean audio performance across the full frequency range; Comfortable, secure fit for long listening sessions; Durable.

Cable is not detachable; More appropriate for professional/studio use than personal listening
