Great sound, durable, and with a little duct tape; your best friend!

The sound is amazing. Silky smooth grippy texture where it should rest on the band, and your arm.

SADLY, the clip immediately broke. I'm not too fond of returning items so I'll probably just duct-tape it to the wrist band.

Also the micro SD card protrudes out the side. You can partially cover it using the rubber strip that should cover the usb/sd card slots. As you can see in the image the card is vulnerable

With that said, I LOVE everything else about this watch.

Edit. This thing is made out of garbage. Tried opening it up to attach the armband another way but the darn screws done stripped! Oh boy.
the speaker does sound good, just the stuff around it is not good.

Alright, less butt hurt. Despite any of its shortcomings, this speaker-watch is the speaker-watch you are looking for! With a little duct tape this quokka has been the sweat resistant trooper /best friend i was looking for.

I bought these the Spring of 2011 and still use them occasionally. The build quality and sound quality have been fantastic! I only use them occasionally though because I'm afraid I'll damage my babies! I always gently clean, wind, and replace in the included zippered pouch after every use. I wish they still made them so I could buy 2 more pairs!

As others have claimed, there is slight sound leakage, but it was not bad by any means, especially if I was listening to something at a reasonable volume level (which was always because they block out sound rather well), and, to get no leakage, I would have to spend far more money on much more expensive headphones (I got these on sale for about $30).

I have been using these regularly for a couple years now and they have never let me down. I used Amazon's most popular bluetooth connector, and these headphones produce amazing sound quality even from ~30 feet away, or about ~20 feet away through a thin wall. This means I can bring it into my bathroom and continue listening to whatever was playing without cutting out at all - incredible!! Definitely the only headphone I've encountered that can do this consistently in this price range.

Beyond this, the buttons on the headphones are well-placed and well-defined, and I almost immediately adapted to and started using them with ease. These also hold a charge for a very long time: Using them about 4-5 hours a day, I would probably only need to charge them about once a week. Obviously, there were periods during this that nothing was playing, but I'd say sound was playing about 80% of the time, and still sounded great and were extremely comfortable even on my somewhat large ears. At most, I would only have to take them off for a few minutes and just rub my ears a little bit or adjust them to put stress on a slightly different spot to continue with complete comfort.

Again, in this price range, I have definitely never found a better set of headphones, and though the resulting build quality might not be top notch, I find that simply being as careful with them as you would with any electronic device has kept there from being any issues with breaking whatsoever.

the sound is great!

and it is durable and i use it in a hard way: twist it in my pocket, throw it on the ground near my bed, listen to it in toilet, etc...

and i am still using it :) (12/14/2013)

I'm generally not a fan of Sony products, but these headphones are excellent.  They're comfortable, have great sound quality, have a long cord, and are extremely durable!

I've been burned by headphones with extremely thin cords before.  They have poor sound quality, and usually break down after a couple months.  Even many expensive headphones have this problem.  But, I've bought 3 sets of these headphones (one for work, one for home, one for backup), and not one has broken yet, after several years of use!

I feel that if the wire was shielded, the set would be even better, but you won't find anything comparable to that for under $70.

I had actually purchased these before a few years ago and they lasted me a solid 3 years or so. I am usually pretty decent at taking care of them (not wrapping cord, ect...) but they went bad after intense use. I was scarred the first few times I stepped on them or dropped them in water but they lasted well through that. The mic works very well although I personally use it more for music it is very useful and I can hear people well and they tell me that they can't tell when I use the mic or not.  I love these so much I bought them again (they are much cheaper now!) and I received them and put them in and the sound is AMAZING plus they stay in my ear through running and are very cozy to wear. They are certainly high quality and the most bang for your buck I've ever seen (I have a decent amount of electronic retail experience) and I would highly recommend them to anyone and everyone!

The sound quality is excellent with these and I love how it stuffs into the ear, making outside noise either muffled or almost silenced. I can finally hear all the soft parts of my songs without turning it up! I actually like that one headphone goes behind the neck so I don't have to deal with two strings dancing in front of my chin when I walk.

The only qualms I have about these are that the little gray rubber bits on the tip sometimes come off, and then it's frantic searching because they're basically useless without the rubber bit. They come with three different sizes, but really, only one of the three sizes fit my small earholes, so it's that one or nothing. I've also heard other people say that theirs break easily but I've had mine for three months and they seem to be doing okay.

I purchased these almost 2 years ago, and they are still going strong. My 3 year old kid has failed to destroy them. However, the twist-able soft buds do easily come off by little hands and has ended up in the mouth of my exploring trouble-maker, (We had to pry her mouth open and retrieve the soft bud prior to her swallowing). Since this event, I've kept them hidden until recent past few months, when she seems to have cut back on eating everything she sees (although a few weeks ago she swallowed the red trackpoint mouse button of my X200 Lenovo Thinkpad and announced with pride that she ate a "red mouse" so we can never be too careful). I use the smallest fitting version, while my husband finds my version too small for him which fall too deep into his ear canals. The length of the wire is more the sufficient especially when sitting back and watching shows/movies on laptops. The sound quality is great.

these are the best quality sound your money can buy. bluetooth transmission of music is not like a DAC or a portable AMP due to the transmission difference, but this pair of speaker still manages to hold very good quality sound. Maybe the UE boombox might have been better due to the cheaper price, but for the negligible difference in price, its worth taking the plunge. Battery life is as advertised(10-12 hours). it doesn't take long to get it to full charge (2-3 hours), and the volume it can go to without noticeable distortion is its maximum volume. Trust me, it is LOUD and pretty cool. The only regret? Maybe I should have gotten the green! Definitely 5 stars and please do not compare them to any wired audio products. I am an audiophile and it is unfair to place this product in comparison with those, which will always produce better sound cuz they are wired.

I bought these headphones about 5 or 6 years ago and they're still going strong.

The two best things about them:
-Great sound quality (especially bass): only the most picky audiophile could complain.
-Durability: they've been on many vacations and car/bus/train rides, and have endured every possible form of abuse. The cords have been bent and yanked many, many times and have yet to short out on me. The folding joints (both ball and hinge) are still in great shape, and the adjustable band still stays firmly in place. The only sign of wear is that the ear padding has worn a little thin.

These headphones are definitely worth what you pay for them, and then some. They can handle a lot of abuse, so unless you severely mistreat them you're set for many years to come.

I have owned a single pair of these for 2.5 years, and they have been truly fantastic. The sound quality and sound cancellation features are both excellent. Here are a few comments I have on my experience, which may not be covered by other reviews:

One of the features I've come to use frequently (and that isn't emblazoned in advertisements) is the detachable stereo mini-jack connection at the base of the headphones. You can completely remove the cord from the headphones and still wear the headphones and use the sound cancellation feature. This has been quite convenient at the office, as is it keeps me from tethering myself to the desk or to a player.

This detachable cord has also saved these headphones numerous times. Before owning these, I went through three (!!) pairs of Bose Triport headphones over the same amount of time--2.5 years. For me, headphone cord tend to get caught on ledges, door handles, corners--anything that sticks out. With my Bose Triports, catching the cord on a ledge a few times would inevitably render the headphones useless. With the ATH-ANC7B, the cord simply detaches from the headphones without damage. Moreover, the cord itself can be replaced, and Audio Technica was kind enough to supply a longer backup cord.

The ATH-ANC7B have broken down in two ways for me. First, the seam for the leather in the ear-cup is glued together. This seam fell apart for me after about 8-12 months, after wearing these headphones and sweating--wearing them is like putting on ear-muffs. I repaired this by applying my own super glue, but these seams should really be sewn together.

The next failure is in one adjustable arm on the headphone band, which happened about 1.5 years after purchase. A piece of plastic broke and the earcup dangles from the headphone band. I've had to use electrical tape to fix this.

The noise cancellation works wonderfully and the sound quality is excellent. The treble and bass are well represented. The sound cancellation removes white noise only, and you can still hear noise that changes rapidly, like voices or sirens. I would also say that music sounds more amplified with the sound cancellation turned on, though I'm not sure whether this is simply due to the noise baseline going down.

All things considered, the headphones have stood the test of time relatively well and continue to delivery excellent music and sound.

The main reason I got this is so that I'm able to listen to both music and exercise videos without wires in the way and without them slipping even when my head is completely upside down when I'm bent over in a stretch or dance move.  And on that aspect these do great!  So skateboarders, extreme jump ropers and gymnasts take note.

As far as bluetooth connectivity goes I have found they also do great.  I can't resonate with the reviewer who had problems with this because I myself never have.

Battery life:  Also great.  I don't have to constantly charge these which I very much appreciate.  I forget what the actual length of battery life is, but it's good.  I've worn them for days while listening hours at a time.

Portable:  They fold up making it easier to carry with you.

Sweatproof/Waterproof: Check

Sound:  Here is where things go sour.  I don't find them to have any better sound quality than other bluetooth headphones.  Also, one of the ways it saves battery is by putting itself in a standby mode whenever the sound is off which can make the sound cut out.  For example- if you're listening to a song that has a couple of seconds of silence in it (let's say it's an artsy band) then it goes into standby and when the silence stops the standbye stops so you end up hearing the stereo sound popping off and on and you end up missing the first second of when the sound started up again.  This is also a pain when you're using it for listening to computer programs with sound- Like when I try to use a language learning software that puts silences in between sentences (to allow the listener to repeat the phrase) it gets annoying as you constantly hear the popping of the on/off during the space between sentences being read... and you often miss the beginning of sentences.  If you're just going to use this to listen to music or audio without moments of silence that last longer than a second this will not be an issue.  There is also a constant static sound in the background when it's on.  It's very faint so it sounds more like white noise in the background, but it's there nevertheless.  This is why I think they cost too much.  For this price there shouldn't be any static noise even if it is blutooth.  It comes with an optional jack connection so you can turn these into wired phones instantly if you want- I have not tested the sound this way yet.

These are uncomfortable at first because you have to break them in (the manual says it takes about 20 hours of wear to do that) then they become more comfortable to wear and the sound also becomes better.  Even after the break in they start to hurt my ears some after about 3-4 hours- but I think this is a small price to pay for a pair that actually stays on your head during flips.

While I can't compare these to the previous J Bud models, The sound is very good. Its bright and clear. I tried a couple of cheaper models but I couldn't hear music when cars passed me by. This model is great for that! It really is rugged too! You would have to try pretty hard to wreck these. Most headphones are so delicate - they seem like the could break if you put any strain on them at all. Not these! I also like the flat cord design - it doesn't bunch up or get twisted. I like the extra sizes of ear buds too. The case is nice  - it even fits my small mp3 player.

You can lay back with these without the plastic getting in the way, they absolutely will not fall off, they pair easily and have great sound.  Functional, though not ideal, as a telephone Bluetooth.  Amazing for music and TV.  I bought a second pair just in case the first pair is lost.

I bought a pair of these Fontopia from Japan in 2001, and am now having to replace them due to the cable fraying (next to the join with the extension).
I've tried many other types of headphone since purchasing these, and none come close for comfort, sound quality and noise reduction from the outside world.
I'm on my second set of silicon buds, be wary, they do go walkabout occasionally. Anyone who's scambled around a floor looking for a RGP contact lens will know the feeling....
So buy them, they're good. But be wary of loosing the buds, and be gentle with the lightweight cord.

Built to last, indeed! I inherited a pair of these from my father, purchased in the late 1970's. If I were to rip them apart (again) and replace the cables, I'm certain they'd be back to their original working order.

As for sound quality, these are the cans that introduced me to what music should sound like, and they are the benchmark for all my other headphones. Some sound better (ATH-M50x), some are more clinical (Ultrasone Pro-550), and some are more comfortable (gluing broken glass to your skull, wrapping it with an Ace bandage, and getting on a roller-coaster).

Seriously... I think I'd rather find out what Jabba the Hutt was talking about when he said "a new definition of pain and suffering", because clearly he's never worn a pair of these for more than about 15 minutes. I think you'd have a better time trying to squeeze your own eyeballs out with a machinist's vise. I've seen other people complain about "clamping force" in some other headphone reviews, and I just laugh. Like when people in Las Vegas complain about freeway traffic to people from LA. Ha! You need to adjust your scale. Can you feel your cranium pressing against your occipital lobe? No? Are  your fingers tingling? No? Your headphones are NOT too tight.

Also, they're heavy. REALLY heavy.  Like, causing-gravitational-distortion, heavy. I recommend a good stretch and a pre-listening neck exercise routine, followed by a good warm-down if you plan on sitting through an entire album with this glorious brick strapped to your dome. I haven't weighed them, but I'm pretty sure your chiropractor would be exceedingly angry with you for buying these.

Did I mention the post-baby creamed spinach color? So, there's that... I can tell you with confidence that the product images are accurate, and that's really what these monstrosities look like. If they won a beauty contest, it would be because everyone was so shocked they had the balls to enter in the first place that they couldn't justify voting against them.

And then there's the lug on the side so you can attach your microphone. If you have one. If you want to run a separate cable. Because this was before TRRS connectors, and Koss apparently is not ever going to change this design. As well they should not.

They're horrible in every way except the one that matters, and that's the sound. If you can't handle these, you don't deserve them.

Awesome sound, nice hardshell case. Favorite earbuds yet!

Edit: one complaint so far, while the tangle-free cord does extremely well with preventing cable knots and tangles, the flat ends of the remote continually catch my shirt, tugging the right earbud when I turn my head. Could be fixed easily by tapering the ends of the remote or adding a taper shaped strain relief there. I fixed with a dab of hotglue.
