These headphones are amazing!  for only $30 they perform as great as the apple in ear headphones volume and bass which i was using before.  they are perfect for the gym if you are going to bench and overheadpress. definitely recommend them to anyone

These headphones when i got them were echoing.  then i read teh box and it said "stereo like" sound.

i do transcription and wear them sometimes eight hours a day!  cannot even use them.

I will keep this simple so you don't have to read a long review. My Wife bought a set of these and I laughed at her getting "Sony" headphones. I bought a pair of Sennheiser HD448 Closed Headphones and then compared the sound to the Sonys and returned the 448's. I then tried a set of Audio Technica Pro Studio Monitor Headphones. Compared them to her Sonys and returned the Audio Technica's.

I tried 4 different headphones all at the $100 range and none of them provided the bass the Sonys did. The shocking part is they are doing this without some sort of bass boost. I ended up buying a set of these and just love the sound. Highs and mids were a bit recessed at first, but I found after a few days of thumping them pretty good, that went away. The burn in is happening pretty quick.

Feels great on the head, the pillows on the ears are really nice. Put in 4 hours of use last night without any comfort problems. I have used them on my iphone and Laptop so far and they are great. I have a Adcom Gfr-700 Receiver which has no headphone jack, so I can't tell you how it sounds on a receiver.

If you like some "thump" in your music, these will do it.

Get them while you can, they don't make headphones like this anymore.

I purchased these headphones for home and portable use, if you are buying these for portable use forget about it, not just because of their size, but they sound like a $50 pair of headphones connected directly to an mp3 player, computer, or a portable amp connected to a mp3 player or computer. I bought a headroom airhead portable amp to power these and they sounded terrible, the bass was bloated and fat, they distorted with increased volume. My first thought these are going back, BUT I noticed that they came with a 1/4 adapter which I could use to try them with my onkyo home theater receiver, so I pluged them in, connected my ipod via line out to the receiver, put them on, turned the ipod on..........OH  MY  GOD, everything cleaned up, the bass, no distortion. I have never heard headphones sound this good, unbelievable, the bass is so clean and accurate in fact the frequency response all the way up the spectrum is so even nothing is over powering or over bearing. My receiver volume goes up to 79, and I took them there, you can crank these headphones with even the most bass heavy music with 0 distortion. I could not begin to imagine what the D7000's sound like, I mean you will hear details of your favorite songs that you haven't heard before, they are very revealing, just make sure the bit rate on your mp3 player is at least 256kbs or higher preferably lossless, put on your favorite song, sit back, then enjoy musical bliss.

These claim to be noise cancelling headphones. There is no noise cancelling capability.

I bought my Beats by OneCall (used) but they were like new they were in perfect condition and it saved me 100 dollars which was great. These are really good headphone if you have the money for them then go and buy them!!! Their is some headphones that have the same sound quality but they look NERDY they don't look good at all. The Beats By Dre. look really good overall i was really satisfied with my Beats I did buy them used but the person who had them just returned the back and since he had them they couldn't sell the Beats as New so they sold them as used my Beats are in perfect condition.

DONT LISTEN TO THESE IDIOTIC UNGRATEFUL PEOPLE. These headphones are amazing. They are PERFECT for everything. They have noise cancelling perfect for going on airplanes. they have leather padding around the headphone speakers and the headband and a snug not too tight not to loose O rotating and fold in mechanism for complete comfort and perfect portability they will fit pretty much anyone. they come with a nice long cable for desktop and laptop computer users. they come with a perfectly portable leather pouch with a tie on it and an adapter for DJs and musical artists i rate these 9.9 out of 10 becuase unfortunately they are not meant for use in bed but they are perfect for anything else.

All I can tell you is that the quality of both the sound and the physical headphones themselves is top notch. They have been refurbished, but I would challenge you to find any evidence of that other than the packaging which is a plastic bag inside a plain box.  Bass is also great.  I am obviously not technically qualified to assess these - I just know good quality sound when I hear it. You can't go wrong with a set of these.

Little messing with onboard audio alc1050 and they sounded like the in-store headphones. Best deal on headphones your will find for music/videos/games. 10/10

For some reason I felt like I was going to get a Bose quality headphone for 20$. My hope we're not achieved... But these are an incredible set of headphones for the money. Comfort is okay, and the quality of sound is okay. Reading the descriptions on here make them seam amazing but they are far from it. The base leaves a lot to be desired but the sound is crisp and clear. Not noise canceling by any means, but does block some outside noise. But again for 20$ you get a great pair of headphones.

You can get these headphones for as little as 13.00 from some of the amazon partners.  Even at $19, these are easily comparable to high end headphones costing 5 times as much.  You hear everything, all the highs and quite a bit of the lows.

Buy them.  You will not be sorry.

I started my search for headphones because my fancy Klipsch headphones lack the bass and noise cancelation. I used to have some beats studios. The band broke. My fault I suppose.. I rigged a fix but then they started picking up wifi signals. I wanted noise cancelation, durability and bass. I went off to buy new beats as no one seems to sell all the features but them. However since they were bought by apple bestbuy won't sell accidental warranties. After a gental ride in my bag from work to home snapped the more rugged previous generation. Total deal breaker.

I spent a week looking at reviews. No one sells bass and good noise cancelation. All the ones at bestbuy were made out of plastic. Cheap, made to squeeze every penny out of the costs. Lets be real, a headphone is a lot of science, engineering. You can make a perfect speaker pretty cheap. The rest, band, hinges, etc are pretty unrelated. Build it like junk and you get a replacement sell.

I found theses guys. I was extremely reluctant. They don't have a battery powered noise active noise isolation. How good could it be? There a small model wearing these in their promo pic. The inner ridge of my ear HATES anything to have any pressure contact against them. If it touches will not work.

But the audiophiles of reddit said out of the pairs I liked these would be a winner.

Currently I'm hanging out at a busy college coffee shop the week before finals. As there is no battery, music does have to be playing. If you have no sound, no power goes to the headphones, no noise cancelation. However I have them on low. I don't hear anyone. Not the crowd, not the music. Granted if I have it really low I can still hear it, but thats the same unless you get pilot style headphones.

The sound is fantastic. Its just like the studios, but maybe a bit better. The bass is STRONG. Though not on my cellphone. You need one of those portable amps, the cellphone just doesn't output to save power. They sound fine just no bass. On my macbook pro I don't even need to run Boom (equalizer application) to get the lows I crave.

I love that you can customize them. I am sad they don't have a 3d file, they have a template for making your own logo. I plan to 3d print one of my own (nerd alert) .. so expect to see a stl on thingiverse in the near future.. Moreso these are one of the few with a METAL BASED BAND. Ontop of that they have an immortal life warranty, where you pay half of new. Even if its your fault, forever. Sadly it can only apply to the same model, but, thats life. ALSO it looks like the headphones are detachable. I see no reason you couldn't buy a new band if the "flex" metal fails. Makes beats look like a toy made to break, eh? (Bet apple will fix it though)

Now the cuffs ARE TOO SMALL.... BUT there is a solution. I ordered mine with XL memory foam. Would have preferred they sold it with an option, not as an addon.. but well thats capitalism.

The first hour they sounded meh, but that was on my cell. I hear they have a 10 hour burn in period. all I know is after a few days they are probably the best headset I have owned.. next to the Klipsch 200 dollar earbuds form 2008. But those hurt to wear all day.

As you can see, I have a beard, thus I must know what I'm talking about. Also theres a 30 or 60 trial period. Not sure how that works with Amazon but it's clear they stand by the product.

Only complaint is I stabbed my hand trying to open some stupid ribbon used as a seal to the box. :-[

These headphones will last you like a month then break. One ear stopped working on both of my pairs.

They certainly are headphones but these are the worst headphones I have ever used.  There is NO bass at all.  It sounds like you are listening to everything through cardboard tubes.  The sound is so tinny and distant that hurt my ears after a short while just watching Youtube videos.

I have never felt as disconcerted over something as trivial as a pair of headphones as I do now. It would take great efforts and extensive study to find a pair equally poor as these. The slightest of movements will remove them from your ear. If one were to cough then his ears would be as bare as when he was without earbuds. They do not remain put either when one is sitting, standing or walking. I beseech you not to purchase this pair, I would not have anybody, no matter their faults, to feel even a moments exasperation of this sort of which I have felt much too long.
