Description

Enjoy pristine audio while listening to your favorite tunes with the Sony MDR-D777LP Altus stereo headphones. The phones owe much of their elite audio quality to Sony’s aura-nomic design, which angles the drivers inside the ear cups parallel to your ears, thereby increasing comfort and delivering a more natural listening environment. The high-definition neodymium drivers, meanwhile, produce an ultra- wide frequency response of 8 Hz to 80 kHz, far wider than most comparably priced headphones. And if you’re weary of cutting off all outside noise when commuting or traveling, you can turn to the built-in ambient sound switch, which lets surrounding sounds penetrate the ear cups. The features add up to a topnotch listening experience, with remarkable highs, deep bass, and exceptional clarity.
Other features include a brushed aluminum design, a foldable housing that fits conveniently into a carrying pouch for easy transport, and a single-sided 3.94- foot cord that minimizes tangles on the move. The MDR-D777LP headphones are backed by a 90- day warranty on labor and a one-year warranty on parts.

Pros
Doesn't use batteries and the design keeps unwanted sounds out without a "noise-canceling" system
Fairly good reproduction of sounds
Cons
Bass could have been better. I got better base from a lower model Sony. It's definitely an upgrade from the Ipod ones... then again anything is ;)
Feels heavy on the ears after a while
Also has a certain constricting effect
In the summer you will sweat in them and wearing sunglasses add discomfort
I really don't see (hear?) the difference while swithing the ambient noise button on and off.
Then again, keep in mind the attractive price tag. These babies go for over 175$ in Canada (not sure of US pricing). Great for listening indoors in a cool environment. It probably was not intended for a 2 hour commute under the sun. ;) Plug these into a tv or a computer (if you have an extension makes things easier) and the sound is great. I will probably buy a lighter pair for when I'm on the run.
I do recommend this product as great headphones under 50$. If the price goes over the 50$ mark, the price/quality ratio just won't do. If you can afford it, go with something better (hint: the lower end of Bose is going for 130$). If not, you get value for your buck with this.
My first impressions are that they look very nice. In the pictures they look silver and black, but in person they definitely are more of a grayish, platinum color. They look much better than the pictures.
They fit quite nicely, though I think they are slightly on the small side for my ears. My ears are definitely on the large side, and they are fine for the most part. They surround your ears, and they do cramp the back part of the earlobe a bit. It's not too bad, but after a few hours you will feel it. Apart from that the fit is great, the pads are soft and feel nice on your head.
These phones block sound pretty well so that when music is playing you won't hear much else. I have not tested them on the bus, but at home they have blocked all noises. The switch on the side doesn't do much... the phones already let a bit of noise in, and so opening up a teeny hole lets in no more than is already being let in. I also have the JVC Marshmallows and those definitely isolate better (not comfortable like these though).
I have little experience with headphones and the like, so I don't really know what to say about the sound quality. Compared to my Marshmallows the bass is definitely weaker and these seem to have a fuller mid-sound. Other than that I have not noticed too much difference. They both sound good to me.
Before buying I read tons of reviews stating that these phones broke soon after purchase. I can definitely see how this would happen since all the parts attaching the phones to the headband seem like flimsy plastic. I'm hoping mine don't break so I have "strengthened" them by placing wires along the plastic connectors then wrapping them in black electrical tape. You can hardly notice this, and I hope it will make it stronger.
PROS:
Short cord (a meter and a quarter maybe). Nice for an iPod.
Comfortable fit
Nice looks
Decent sound (i think)
Can be had very cheaply
Good (not great) isolation
CONS:
Weak attachments to the cups... likely to break.
Weak base response (though not too bad when I boost the bass on my iPod).
Ambient switches really don't do much.
Pros:
Good clean quality
Portable, look cool
Only $30-$40 on amazon
cons:
Bright sound
Hard clamp on the head, can become uncomfortable and even cause headaches after 20-30 minutes.
So-so build quality, may break easily.
Definitely worth $30, probably not more than $60, due to the discomfort.
The triports sound slightly better and are much more comfy.
Build quality seems good for a $20-30 design, but again, a joke at the $100 list. They have a thin, single 50" cord with right-angle 1/8" plug that is convenient for use with portable devices, but may require an extension for use with a desktop PC or stereo. The earcups are tall and narrow, and as they are nominally a circumaural design, if you have wide ears or wear eyeglasses you may not find them comfortable. The clamping force is about right - more than my PX-100s and much less than my head-vise HD-280s.
My advice to anyone needing affordable portable headphones is to immediately get themselves a pair of the remarkably good Sennheiser PX100s (see the 600+ reviews on Amazon). For strictly home use, a pair of either MDR-V600s, or if you cranium is narrow enough for them, HD-280s are excellent choices, but don't let the illusion of a huge discount lure you into the D777s...
I'm a musician and an audio instructor at a college. These headphones revealed (either in an inferior, but most likely superior audio build) that the squashing of the dynamics in modern music mastering has killed the quality of music in the misguided achievement of making songs "loud". Look it up, it's a real problem. Google "dynamic wars" or the the "Waves L2" and you'll see.
I went back and listened to the 80's, early 90's, 70's. Everything glimmered. Oh, and one modern recording sounded golden "Silver Lining" by Rilo Kiley (and it was an AAC file from Itunes, which is technically compromised goods). I'm going to buy a few pairs to give out to my friends who do music. I'm going to tell them that after their music is mastered, if it sounds bad in these, send it back and do it again. These are the yardstick to measure music quality, because something in the build won't let the music lie. Listen to something old and hear the details. You might cry, too.
Oh yeah, only 4 stars. Sound is awesome and they fit my ears right. It's just that the build is a bit janky.
