Solid value in headphones
586944
Every night, I listen to a CD (Holosync by Centerpointe) while going to sleep.  The CD has a range of frequencies, from deep bass (down to as low as 20 Hz) to mid-range.  Also, since I travel frequently, the headphones need to be sturdy.

When my previous headphones (by Sennheiser) died, I purchased these to use for the CD instead.

From an audio quality standpoint, with my old Sennheiser headphones, I could hear some subtle nuances in the audio, at slightly lower volume, than I can with these headphones.  Then again, the Sennheiser headphones cost $250, while these cost $70.

However, my Sony headphones serve me very well.  They produce good (but not great) sound, so I can clearly hear the bass and mid-range without turning up the volume.  Because the ear cups are soft and comfortable, the top is padded, and the headphones themselves are lightweight, I can easily fall sleep with the headphones on.

The coiled cord is extremely handy, keeping the headphones from becoming too tangled.

Beyond that, the headphones themselves are sturdy, standing up to a year of being put in a squished suitcase without a scratch.  Also, they are very affordable (about $70 from Amazon.com).

The only issue is, if I wanted headphones to use while working out, these headphones wouldn't do because the padding would likely absorb my sweat.  However, for my non-workout needs, these are excellent.

Although the audio isn't quite professional quality, these are an excellent set of headphones for the money.

They may not be the best headphones out there, but they certainly are a noticeable improvement over most $20 pairs I've purchased. Bass is pretty good, given your player has some output. Only complaint is that the headphone wires separated after some minor pull. Still lasted several months and well worth buying again (Just got the even cheaper orange pair as replacements).

Quickly, these are some fantastic headphones that I've been enjoying for the past few weeks.

-Very comfortable, they cup over the ear and don't cause any head/ear pain
-Buttons are easy to use, easy to find
-Sound is great, not perfect, but well done
-Noise cancel is just as good as more expensive headphones
-Battery life is good, casual use at work last a few weeks.

There are a few different opinions in the reviews, but some are misdirected at the sound instead of the headphones.  If you are using cheap computer speakers, a 128 kbit/s MP3 compared to a 256 kbit/s AAC is not easily differential to a normal person's ears.  Now when you use a nice pair of headphones, the difference becomes immediate.  If your music source isn't up to par, buying good headphones are going to sound worse than those cheap built in speakers or default white iPod ear buds.

I noticed a very nice upgrade in sound quality compared to other noise canceling headphones, but performance slightly less than good quality stereo studio headphones. This was with decent sound source music files.  I'm not going to get into FLAC files, they are the epitome of sound audiophiles but wasted on most casual users such as myself.  So I would definitely recommend these to anyone looking for a great value on noise canceling headgear.  These sony headphones completely drown out the AC in the office, and almost all noise that is more than one cubicle away.  I can wear them for long periods of time with no issues and have been really happy with them so far.  Just pick up some rechargeable triple A batteries for prolong use and you should be enjoying music in a whole new way.

Excellent value for the money.  A little bass-heavy, but not too bad.  With a reference track, you can mix professional audio with these.

I have a set of Sony MDR 7506 Professional Studio-quality monitor headphones, and while the HD 202 II isn't as clean, clear, and flat, it's probably about 80% of the Sony's quality.

The ear cups are a bit small, and you have to get them in just the right place or they'll get uncomfortable after a couple of hours.  I find that if I push them back so they're just touching the front part of my ear, that's the best spot for long sessions.

On the plus side, these don't slide off, without being overly tight.

As others have mentioned, the cord is too long most of the time, but is a good option every so often.  The included cord wrap accessory is great if you want to go walking with an MP3 player, but is difficult to manage when you want to extend or shrink the cord a couple of feet for specific situations.  After using it for a few days, I gave up on it due to the hassle of making length adjustments.

Sound: 4/5 very good for what they are. Balanced sound. Bass isn't heavy but very much present. Vocals comes through loud and clear. Plenty of volume. I've heard no complaints from people when speaking on the phone using these headphones.
Comfort: 4/5. They're circumaural so they fit around the ear (resting on the scalp/face). I have rather large ears and they manage to make it around them when positioned right. Theyre also light weight and have plenty of adjustability to fit pretty much any head.
Packaging: 5/5. Case is sleek and well padded. Headphones fit snuggly inside.
Features: 5/5. Minimal, but very efficient controls. Play/pause answers and ends calls along with playing and pausing music/video.  Switch the headphones on and a voice tells you what device you're connected to and how much battery life you have left. Extremely simple and useful. Also, there's a headphone port in case you felt like regressing (lol).
Battery Life: 5/5 Great.
Value: 5/5. My first time buying a high end bluetooth headset, but I feel like these deserve the great reviews and I sleep well at night knowing I paid $200+ for these. They work all the time and work well.
Summary: These probably aren't the best headphones you can buy at this price, but I doubt there are many BLUETOOTH headphones out there that can top these. A sound purchase indeed.

For wireless headphones in the $20 range, I wasn't expecting much, but they do their job admirably.

Sound quality is, as expected, fairly close to the low end of the audio spectrum, though a step up from pack-in earbuds. Bass is weak and muffled. However, midrange is very responsive, making call audio clear when in use. The microphone is also acceptable, and call participants had little trouble hearing me (though they did note I sounded further away from the phone than normal).

As a media headphone, the aforementioned sound quality leaves much to be desired, but they do pack independent volume control and seek buttons on the side of the headset, which is a nice, convenient touch that lets me leave my phone screen off to switch songs.

They are about as comfortable as competing Sony behind-the-ear headphones, which is to say, not terrible. They might not be the best for extended listening, but an hour or two shouldn't be an issue.

Recommended!

After 9 months using these, I'm pretty happy with this pair of headphones.

SOUND--I'm not a music snob nor have the ear of what GOOD sound is supposed be, like a DJ or music producer. But I do think this pair is a great value for what it sounds vs what it costs. I mean, the $200+ headphones sound terrific. But these at this price is pretty good.

CONNECTIVITY--connecting via Bluetooth is usually pretty easy. There are times that it cuts out or the controls don't work, but I think it's mostly my iPhone screwing up (don't ask me how I guess this, I just think it's the device more than the headphones). If it does glitch a bit, I "forget" the headphones on my iPhone and then "pair" it again and it's all fixed. So, not bad!

COMFORT--it's relatively comfortable. I usually wear them for long stretches, but if after 2 or 3 hours they can begin to squeeze on the ears. But again, that's 2 or 3 hours! A hidden bonus is the over-the-ears style makes them GREAT ear muffs during the winter and keep you warm. On the other end, they can be a little hot in the summer.

DURABILITY--the headphones seem a little rickety(??) but honestly it's been pretty durable. I've dropped them and shoved them into bags. If you do wear them, they do expand (as in the arch becomes wider) and you would think they would stay stretched out and :(  But after a good while, they do go back to their original snugness. It's reassuring for sure.

I've been using these headphones at work for the past year, thinking every time I put them on how lucky I was to find them in a box of stuff that was getting thrown away.  I imagined they had to be at least $50.00 judging by their sound, build quality and how much my company usually tends to spend on bulk items.  I couldn't believe they were being decomm'ed just because someone had already worn them.

I'm buying two pair right now for home and travel because these headphones are SOLID.  The cord is great (maybe a bit too long for traveling), but it's excellent for stationary use if you're the kind of person who dislikes replacing/charging batteries or even the kind of person who has been through damaging 1/8 inch audio jacks because your cord was too short in the past.  I can wear them for about three hours straight without getting uncomfortable, but your ears will begin to get sore after extended use.  The pleather cushioning isn't the greatest and they do grip your head rather tightly, which helps in noise cancellation.  The headband is also cushioned and never irritates the top of your head (coming from someone with hair, anyway).

Now, how do they sound?  9/10.  I swear by my Sony MDR V55's, but these are right there next to them for an insanely cheap price.  I'm sure they don't technically compare at all, but they're basic performance is very surprising.  They handle bass exceptionally well, treble is never cheap and tinny, and mids are very apparent and warm.  They aren't the "warmest" sounding headphones I've ever had and they're not as crisp as most $200.00 Bose cans I've owned, but I am honestly blown away by the cost/performance ratio.  I'm also mildly impressed by how much sound they don't leak.  These aren't noise-cancelling headphones, so you'll be cranking them quite a bit if you're using public transportation.  I tested them in a pretty silent room without any white noise and found that if they are pressed to someone's head and fed 75% volume from an iPhone (Metric was playing at the time), you could just barely hear it as a bystander sitting right next to them.  On a plane or a bus, the passenger next to you should be safe from being annoyed.

All in all, there's no reason not to buy these - even if you don't need a set of headphones now, they make a heck of a backup pair.  You're looking at one of those rare moments in which you're getting a LOT more than you pay for.  5 Stars.

These headphones sound good! They have deep bass and mid-range; the highs are a not as crisp as they could be, but if you don't want and/or have 300 dollars to spend for top brand headphones these are a good option. They're comfortable and I wore them for a couple of hours and didn't feel any discomfort on my head. I listen to all types of music and I just adjusted my EQ settings on my phone, MP3 player and they sound good. I would buy these again. Battery life is good too, I charged them according to the manufacture's recommendation and they work just as advertised. I was able to talk and hear my phone calls and the person on the other end heard me loud and clear; no problems there. The controls are easy to use and feel solid when pressed. The build and design is quality and feel sturdy. I ordered the black color and I like the way they look; very low key look and stylish without being "look at me" vibe. Only wish they come with a travel case, but that's not a deal breaker Amazon sales after market cases.

At around $25 I feel content with this purchase. These will certainly outperform any cheapo headphones that came standard with your MP3 or CD player. They will also outperform most, if not all, entry level "upgrade" headphones you may find at the local big box electronics retailer (price range $20-30).

On the downside the design is a bit clumsy for a model advertised as "portable". I would call them more semi-portable because of the bulky (albeight lightweight plastic) ear cup design. My other concern is that the design seems a bit fragile, the build quality and materials seem a bit "cheap". Even at this price point I was expecting a somewhat higher build quality due to the brand.

In the end at the total Amazon price of <$27 these are an excellent value heaphone.

They feel sturdy without being bulky, and are comfortable to wear. Also, like one of the previous reviewers mentioned the sound cancelling is really good, I can barely hear anything just from wearing them. The sound quality is overall good; I think the base is a little lacking (and the only reason I probably noticed was that I tend to listen to electronic and disco music, and these are probably the second pair of headphones over $30 that I've bought that were lacking. That being said it's not a deal breaker, and unless you're really picky about headphones these are great! Would buy again~

To my non-audiophile ears (and come on, do you really believe half of what they say?), these are quite good, if a little lacking in bass. For me, this isn't really a bad thing, as I don't even like bass all that much, but I thought it worth mentioning. The highs and mids are very crisp and clear, and I feel more "present" while wearing these than any other headphones I've worn recently. The volume is good, I keep my device (Nexus 5) at one of the lowest volume settings for normal listening. They come with 3 different tip sizes in a airtight, sealed foil package. They stay in my ears well and are comfortable to me, but the hard edge on the backside would probably be uncomfortable for smaller ears (I do wear the smallest tips, so maybe this won't be a problem for most). The fit and finish is great, and I love the placement of the button/microphone: right at jaw-level, where it won't get lost in or blocked by whatever clothing you happen to be wearing. A solid 4/5 stars for the average user.

As an owner of these, HD558s and Momentum 2.0s, I can honestly say that these are an absolute steal for under $30. They are a huge upgrade over any stock pair of headphones i.e. earbuds, etc. On a measure of price to performance, these may be one of the best values out there.

The key to these headphones is their value and level of bass for the money. They provide a pumped-up bass and laid-back treble/midrange that works well with portable music players. The in-line microphone with volume control and play/pause - answer/hangup button works well. Comfort is also a key feature of these headphones - very soft and comfortable. Also the cable is replaceable and is the standard 4 conductor 3.5mm connection on each end.

Heads up! Some devices will not accept the 4 connector 3.5mm plug! This is a fairly new concept and it part of adding the microphone connection... often the connection on, say a laptop or older MP3 player won't allow the plug to go in all the way. The work-around is to purchase a 3 conductor 3.5mm headphone cable and give up the microphone feature. Those are sold here on Amazon at very low prices. Just don't try to force the plug in as you may damage the player.

What these are not is an audiophile grade product. Don't let the brand name fool you - this is not the Nakamichi of decades past, but just another case of a recycled premium brand from the past for brand recognition. Also their retail price is a joke. BUT their true street price is a bargain. Do these compare with true studio monitor headphones? Not a chance. In my opinion, their closest real world rival is the Skullcandy Hesh Mic, which can be found at massive discounts. The Hesh has a more neutral balanced sound and better bass capability on home audio equipment - but these feel more solid.

For their real intended market (never mind the studio hype), these are a good buy. Heavy bass and forgiving treble (good for those low bit rate MP3 files). Good sensitivity, with ample volume on my Motorola Moto G phone. For the audiophile market and users who are jumping over the Nakamichi brand, naaaaa - only the logo has ties to the past.

These headphones are a great value!  After reading about these in several reviews online, I decided to get them for use on my home computer for general use as well as video editing.  These headphones easily perform at the level of $100+ units.  The have excellent bass response but not overly exaggerated. The foam is large enough to completely cover my ears (which are on the larger side since I am 6'3") and are very comfortable to wear for extended periods of time.  Noise canceling is not the best I have tried but certainly does a great job. The top foam padded strap makes for a very comfortable setup even when wearing them for extended periods of time.  After 10 minutes, I could barely tell they were there.

These are the first over the ear bluetooth headphones I have owned, although I own several pairs of wired headphones and earbuds that I was able to compare these to.  The build quality on these seems pretty good with most parts made of metal, soft cushions on the ear cups and head band.  Overall, they seem comfortable to wear for extended periods of time, although they are a bit heavy.  They synced right up to my iPhone 6s with no problem.  Just hold the power button down until it shows up on your phone's bluetooth pairing screen.  The sound stage is well separated and compares favorably to headphones that are much more expensive.  The bass is big and booming, most likely due to the 57mm drivers which is larger than most headphones on the market.  The controls are hidden on the outside of the ear cup and not totally intuitive.  You push on the top or bottom to turn the volume up or down, and push the left or right side to skip tracks.  One negative that I noticed is that the bass does not accurately capture the punch of a kick drum very well.  The mid bass seems to be drowned out by the sub bass, similarly to having a pair of 15" speakers in your car.  Very bass heavy and would probably work fine if you intend to primarily listen to hip hop, electronic, or pop music.  However, not the best choice for rock or other live instrumentation.  I am a musician and nightclub DJ so I have a fair bit of experience with sound reproduction so take that for what it is worth.  Overall, I think these are good headphones at a great price.  I did have an issue with one channel cutting out when I applied pressure to one of the buttons to adjust volume.  I returned for a second pair that did not have this issue, but makes me leery about the longevity of these headphones.  Also, I noticed quite a bit of sound leakage at higher volume.  Even when I pressed the ear cups against a table or my leg to simulate another person wearing them in the same room, the noise was quite noticeable at anything over 50% volume.  Personally, I always listen to music fairly loud so these might not work for me in quiet locations where I might bother other people.  I was also comfortably able to listen to music at full volume and actually wished these were capable of going a little louder.

Pros:
Sturdy metal design
Comfortable ear cups and headband
Easy Syncing
Good sound with lots of bass

Cons:
Heavy
Not super intuitive controls
Bass is boomy but not punchy (not great for live instrumentation music)
Excessive sound leakage
Not quite loud enough
Longevity (had issues with first pair cutting out)

Overall, I would still recommend these headphones if you are looking for a budget over the ear headphone that has lots of bass.  Just make sure you aren't listening to them in a library or on a plane as your neighbors will surely hear everything.

I purchased these along with several other headphones to find the best bang for the buck.
Here is a quick breakdown of why these were my #1 choice.
Pros:

Audio quality:
-Excellent bass, mids and highs are fairly clear, overall they give you a well balanced and LOUD (for not requiring batteries) experience. These were the loudest headphones I tested by far, moreover, they did not distort the sound at all.

Build Quality:
 -When you unfold these they give you a satisfying "click". The headband is fairly flexible although it is made of plastic. They fit on ear comfortably and the ear pads are very soft leather.

Price.
-When I Purchased these for around $60 they were well worth it and easily outperformed some other $100+ headphones I have tested.

Cons:
-Prolonged use (2hr+ for me) can be slightly uncomfortable because the headband is fairly tight. (I have an average sized head)

The mids and highs may not be on par with audiophile requirements.(Although better 3 other similarly priced headphones, they could not compare to the ATH-50's)
