Pros: Sennheiser quality, Sennheiser sound. I really don't think you will find a better designed pair of headphones in this price range, except maybe for other similar models BY Sennheiser.

Cons: I've been a Sennheiser user for many years. WHY they've decided to make newer models SMALLER is beyond me. Granted, I have a big fat robotic head--but these were a VERY tight fit, so much so that I almost returned them. However, I soon discovered that the padding along the top is removable (the seam along the top comes apart like a ziploc bag)--how's THAT for top-of-the-line design! Still, my old HD-545's fit me WAY better than the HD-555 or these new HD-280PRO's.

Overall Review: If you're trying to decide between the HD-555's and the HD-280's, it really comes down to what you want to hear. If you listen to loud music and want a very comfortable fit with very open sound, take the HD-555's. If you want to hear EVERY LITTLE NUANCE (i.e. more instrumental type stuff) and have the rest of the world shut out like you're wearing gun muffs, take the HD-280's.

Pros: These headphones are comfortable. Lets face it, all headphones cause fatigue after a while. Until they are made out of air thats just how it is. I wear them for hours on end at my job as it keeps me on task. At the 2 hour mark I start to feel them, at the 4 hour mark I want them off. This is actually better than any I have ever owned. The sound quality is very good and the headphones are very durable and seem like the will last. Tje sound quality is not the best in the world but very good for a sub hun set of headponzies.

Cons: or convicts are people who have been in prison. This is an unfair term because if they have served their sentence they are just "people" as the have paid their debt to society. So there are no cons in life or in this headphone review.

Pros: - Fantastic sound quality - Good bass performance - Passive noise cancellation is nice, but once I have music playing I can't hear a thing around me.

Cons: - Not the best for travel in terms of mobility. They are a charm once you put them on in a plane, but storing them can be a hassle. Not worth taking off a star, they aren't intended for constant mobile use. - Have to be careful with the thick cable to prevent bending.

Overall Review: - I have worn these almost daily for almost 6 years at work. The fact that these headphones are still being sold is a testament to the timeless quality of the product. If I were to buy new headphones, I would probably buy these again once my current ones are completely shredded and no longer comfortable to wear. - My pair is finally showing some wear in one of the earpieces and the leather on the bridge overhead is coming off. I read about this in reviews 6 years ago, and well, I've finally gotten to that point.

Pros: - Best headphones. - Extraordinary quality and longevity. - Got 'em cheap (thanks Newegg!) - Fold in on themselves for easy storage.

Cons: - Nothing.

Overall Review: I bought the HD 280 Pro back in 2010. That was about four years ago. I bought them after my other (similar looking, but from a different company) headphones started to lose their plastic covering. Whatever those other headphones were, they starting falling apart in very little time. This Sennheiser, however, has remained in what appears to be perfect condition for four years now. The thin plastic that's covering the ear cushions has miraculously stayed completely intact all these years. They sound great. While not noise cancelling, they do a great job at blocking out external noise. But most importantly, they're made of quality materials that remind me of the good old days when things didn't break. The fact that I took time out of my day, four years later, to write this review, should be its own testament to their quality.

Pros: Let's face it, Sennheiser has, for many decades, specialized in small transducers: microphones, headphones, now earbuds. They don't even venture into large speakers, an area where other headphone companies got their start, and, in my opinion, should have just remained. Instead, Sennheiser maintains its R&D focus on what it's always done best, and better than anyone else. Perhaps some of their little earbud models are not quite as good as their others, but their headphones have always been the tops, like their microphones. I've had a pair of HD 414s since 1974, and I'm not the only one: they still keep the foam coverings in stock for all of us who've had them for 38 years. I've worked in radio and professional audio recording and mixing, and can say, absolutely without hesitation, that the HD 280 PRO are absolutely the best I've ever used. Can't recall what the frequency response curve looks like, but it must be as close to flat as is possible. I use them with my stereo, TV, computer -- anything. The sound is as real and true as being there. No emphasis in any particular frequency regions: just true, perfect sound, music, everything. Loud: no distortion. Normal level: perfect. Soft: you still hear everything. Everything. These are the ones to get. You will not be sorry.

Cons: Absolutely none. Nada. Zip. Zilch.

Overall Review: I just might get a second pair. Just because they are that good.

Pros: I honestly cannot recommend these headphones enough. There is nothing anywhere near them for the price in terms of build quality, wearability, and durability. Sound is excellent, I haven't tested many cans since buying these but sound is amazingly good and almost as good as anything I've ever heard (at much higher price points).

Cons: The first pair I received did have a dead ear cup but 6 years on with the replacement pair that Sennheiser sent I've had not a single disappointment despite daily use and tortuous conditions.

Pros: These headphones have been with me since Feb 2006. The only thing to ever go wrong with them is the glue holding one of the ear pads finally coming off at this end of last year (dec 1013). I have moved 6 times since then and go to about 10-20 LAN parties a year (almost every weekend in 2006/7. I cannot find any damage to this set at all despite them being crammed into a backpack. They fit perfectly around my ear and seal out most ambient sound and chatter. I can hear audio pretty clearly when on a Q-400 Turboprop airplane.

Cons: With this set, you won't get that "I'm a victim of really good marketing and ignorantly overpaid for a mediocre product" appearance ever so desired by today's youth when boarding an airplane or bus.

Overall Review: It is kinda sad that it cost almost 1/3rd the price of the set for replacement ear pads.

Pros: Very flat response, comfortable, light, replaceable parts

Cons: If you don't have the right shape head, they might hurt your ears

Overall Review: These are awesome quality and by far the nicest headphones I've ever owned. One note is that they'll sound terrible right out of the box. I gave them 24 hours playing at almost full blast before putting them on my head and listening, and wow they sound great. The break-in is quick compared to some of the other cans I've read reviews on.
