These are cheap and badly build headphones. Plastic parts are not well fixed together, so they tend to make noises if you move the phones. The screw stand from one of the phones broke, so I had to open it, and I found something very interesting: the speaker is encapsulated in the body of a smaller on-the-ear sony headphones. They just made some larger cans and attached another phone inside! Nice way to make money!
Enough said about its flaws. I have had them for 13 years now, and they are working well. The plastic leather-like covering of the foams stripped out, leaving a soft cloth that just makes them more comfortable. And that's where they kick ass to other similar and even much more expansive models: they are cozy. They fit wonderfully. Even with glasses on, they don't get too hot or uncomfortable.
Sound quality is quite good. Some incoherences in the treble, rolling off in higher frequencies, and a bass with enough punch but lacking depth. Timbre is correct, and human voices sound good.
When I bought them, I tried some other models available in the store, like Technics, Pioneer and Philips (back then, in 99, there weren't to much brands to choose from). Chose the Sonys for their natural sonic presentation and their very competitive price.

I have lived with these headphones for over 9 years.
Frankly I never compared them to any other pair, I just used them for everyting, music, movie and tv, and in all those year I never considered buying anything better.
After 9 years the pleather came off the ear cushions, which had a negative effect on the bass, a too lean bass for most music and I went to look for a new pair.

In retrospect the sound is and was pretty good for the money ($50).
After this pair I got the Audio Technica ATH-A500's and although the A500's are clearly better in every aspect, I never felt I had missed something with the Sony's nor did I feel that all of the sudden the Sony's sounded poor in comparison with the clearly superior A500's.

The CD270's are/were very well tonally balanced headphones, with a respectable bass, solid soundstage and slighlty rolled-off highs.
And they are very sturdy as well, apart from the pleather (which came off after 9 years) I never had to replace a cable or anything else.

Price and there Sony

none

Great for the money, and they sound so good. They feel good on your head too.

Price. I, however, got ripped off. And they're really comfortable. Nice sound, except the low end.

Bass is SERIOUSLY lacking. Thin latexy type material is falling off the pads, after 2.5 years of HEAVY use.

I'd like to revise my previous review. In the past year I've learned vast amounts about high end headphones, and am going to purchase some Grado SR325 headphones. These old Sonys have done me well for now, however. Their sound is good, but they just don't go loud enough, and the bass isn't deep or rich enough for my tastes. The value is excellent, however.

These Headphones are a bargain. No question
I bought them for $40AUD, which is roughly 25USD

The comfort of wearing them is great, and there is nothing to complain about.

The sound quality is unbeatable at the cost, probably a little limited at the very bottom of the Bass scale, but thats about it. The detail they can produce is awesome, and they run happily off anything (I normally use them in my CD-ROM drive, Plugged in to the front!)

I've listened to the more expensive refernece-style headphones, and while they do sound a liiitle better, there is nothing in the world that is gonna sound so good for such a cheap cost.

Bad part: I've now realised how shitty my speaker system is, and so now i have to spend exorbirant money on Speakers!

honestly cheap, comfortable and won't make you really unhappy

honestly cheap; won't bring you any nearer to music than you could expect for that price

These ones are closed headphones and that is also what they sound like. Not that I do not like closed headphones but these ones are really coffins. They lack a lot of what brings some kind fresh air to music in general and dynamic music in special. Well, in detail:
They just can't reproduce all that what is inside good (recorded) music! For example when you expect music to be explosive and blasting you away you will just get some average sounding basses which are not really differentiated. It is just SOME bass there - not powerful, not too deep and somehow indefined.
Then you will hear well balanced mids. Yes, really, that is what they like and can reproduce: mids in all imaginable variations - not extraordinary but adequate for this piece of plastic.
Further up the frequencies you will notice (maybe not at once, but you will!) a falloff of high percussioned sounds and similar high frequencies. That made me curious and I tested them with a computer-generated sine-waves from 10 kHz up to the end of what I can actually recognize at low general volume (i.e. about 18 Khz left and right). And to everyones great surprise (sic!) they did not perform far above 14.5 kHz. They just cut off there!
And so, apart from their inability to be powerful dynamic they lack that brilliance that one should expect if you imagine that the chassis are only a few millimetres next to your ears and there is nothing that could possibly alter or block it.
To sum it up - for the given price they are maybe not as bad as I described them. It is just the fact that I love music and these headphones are really killing too much of it for that I could recommend them. If you just want a cheap pair headphones then go on and buy them! In any other case - think about spending a few bucks more and give these sennheisers, that I'm just listening to, a try! You won't regret it!

not really used, but tested several sennheiser, sony and koss + really cheap ones; and right now a brand new pair of sennheiser hd-580

Clean sounding, well rounded ... !!! COMFORTABLE !!!

Lowest bass is not defined

This headphone is my work headphone and is very neutral
headphone. Very good for listening to music, that does not
require alot of base. Mids and defined enough to enjoy and
smooth enough that bad tracks sound little better.
This is by no means a studio monitor, but excellent
listening headphone.
I tried headphones in range of 50 -600$ CDN.
This one is MOST comfortable. For that I would recommend
this headphone set as headphones for work in office.
They are closed, super comfortable, cheap and make music
sound awfully good for the office environment.
I paid somewhere ~ 80$CDN for these, excellent overall deal.
Oh and these are excellent fit with glasses. I have 200$
pair of dj1003s from Ministy of Sound for monitors, and
this one is by far more comfortable. I had to get contacts,
just to use other headphones.
Sony makes utter crap sometimes, but this is one of the exceptions.

Very nice. I bought them last year for around $90 Canadian Dollars, and they're not bad.
I use them mostly on my computer to play high quality 256kbps MP3 files, using a mp3 player with a 20 band equalizer.

with the right adjustment these headphones are pretty darn good, the low end is a bit lacking in richness though.

high end it not bright or tinny whatsoever, and the midrange is not annoying at all (with correct adjustment, of course. i dont like much midrange)

they fare quite well at high volumes, and start cracking up at a volume i dont care to go to often. although i think i may have damaged the left speaker by doing so :-)

i definately reccomend these for a high-mid class pair of headphones

I have been using the Sony MDR-CD270 for over 1.5 years. I have never liked listening thru headphones. I only listen them when I have to. Previously I had bad experiences with the Koss and the Senheiser. The Koss was extraordinarily heavy, uncomfortable and most important: had mediocre sound quality. The Senheisers were the lowest-fi headphones I have used regardless of price. My son doesn't use them even with the computer. The cheap Philips headphones were each different, some offering very good sound for the price, but generally lacking power bandwidth especially at the bass, that is overloading with bass at high listening levels.

Since I am not a great fan of headphone listening, I would probably never plan to buy a very expensive headphone, especially after listening to the MDR-CD270!

For a start, the MDR-CD270 is quite lightweight for its size, and is very comfortable. Though they are a closed-back design they don't give you that being isolated feeling. Its very easy to determine which side is left or right (even in dark), very much unlike most witlessly designed Senheisers. It has a straight and over 3.5 meter (about 12 feet) long cable. Its plug is of good quality and looks like gold plated. The adapter at the plug end is screw-on type, rather than push-fit. This is good as it doesn't get off unintentionally.

Its sound is the greatest surprise. When I switch off my Yamaha NS1000M monitor speakers (which I believe are the greatest speakers on this planet in the price range up to and in many instances probably more than $10000) and put them on, I have found out that they are the only headphones I can stand.

The taste of its sound is like a well cooked dinner. You know, just the right amount of everything, the correct ingredients. The bass is very very good, though not in the same league as subwoofers. The mids and hi's are transparent enough and very clean. And most important tonal balance is very good.

If you value headphone listening very much, and plan to do at least half of your music listening thru headphones, go ahead and venture to pursue your quest of finding better phones. But you'll have to spend a great deal more than the price of MDR-CD270 to excel it.

On the other hand, if you are like me, these are the phones to buy. They are good enough and represent an unbelievably good value.
