Big sound, little package. Headphones look out (I'm looking at you, Bose)

I've had these buds for almost two years now, they're still working perfectly, still putting a grin on my face when I hear a cello or bass assert its presence with strength and control. I've been on a hunt for the perfect buds for about five years now so I'm familiar with competing products. Typically, presence and range response is excellent with over-ear headphones but the bulk of the thing and feeling conspicuous while wearing them made the perfect pair of buds worth the hunt.

Pros:
-- Strong, CONTROLLED, bass response--even at low volumes
-- Treble is articulate without the sting of Shure's E-series
-- The button on lanyard means you don't have to sacrifice remote control when springing for non-Apple buds
-- Plug design fits well for many ear sizes, stays firmly in  place, and unlike the E-series is FAR more resistant to wax buildup in the channel between the ear cone and the driver inside the bud.
-- Soft, flexible cord easily reels and is resistant to twisting over extended use

Cons:
-- Microphone quality is quite poor. I didn't use my original earbuds for many calls but I can say for sure that I received many more complaints about voice quality when using the HF2s. I don't use the feature unless I'm in a quiet room or there is no wind.
-- 45 degree gusset between the jack and the trailing cable is kind of a nuisance (though marginally better than a set with no angle).

As I said, I've had these for almost two years and I'm very pleased with my purchase but the poor microphone quality forced me to award only four stars. I've owned the Shure E2C, Shure SE115m, and a pair of Sennheisers (I don't recall the model). I can say with confidence these are the clear winner. Tonal balance is excellent (my Shures tended to have unruly response starting in the 8k range, becoming unbearable in the 16k range) and with the delicate but very strong silicone buds they are exceptionally comfortable. I have a tragus piercing which, as one might expect, presents a unique fit challenge. This is also the first pair that I have been able to forget was in my ear AND stay in place while I'm running.

These pack incredible sound in a small package.  I am generally not a fan of small speakers, but these have a great mid-range.  Awesome speakers!  I have ordered 4 more after original purchase.  Highly recommend for when a larger speaker is not possible.  I replaced Bose speakers.  In comparison the Bose are horrible.

So here we have the first pair of $350 headphones I've ever owned. Come to that, the first pair of headphones I've ever owned that I didn't get from an airline.

These are pretty impressive headphones. They come in a rather spiffy black and red case that folds out to display the headphones and the many cables and plugs that come with them. I don't know what half of these are for, but they look impressive, which is what one wants with headphones, right?

The headphones come with a traveling case that they fold up neatly into. This makes it quite simple to take them along on an airplane. One thing they don't come with is much in the way of instructions on what cables to use, what does what and things of that nature. I suspect true audiophiles will know already.

Anyhow, despite their rather large size, they are fairly light and fit well. I had no problem wearing them for an hour straight. Longer than two hours might be a problem, but I'd have to just see for myself.

I did a series of tests using different kinds of media to hear how these sounded. Here's the results of my somewhat amateur tests.

Cell phone headset test: Yes, these can work as a cellphone headset. It even comes with a mic! I tested mine on my&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Nokia-5310-Unlocked-Cell-Phone-with-2-MP-Camera-MP3-Video-Player-MicroSD-Slot-U-S-Version-with-Warranty-Blue/dp/B0017QL99M/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Nokia 5310 Unlocked Cell Phone with 2 MP Camera, MP3/Video Player, MicroSD Slot--U.S. Version with Warranty (Blue)</a>. They worked fairly well. I could clearly hear my friend and he could hear me, though I gather he couldn't hear me all that well. Still, I think I'll stick with a Bluetooth for talking.

Cell phone headphones test: I could hear my MP3's just fine. Not noticibly better than any other headphones I've used on the phone, but it worked alright.

Downloaded video test: Aces! I could hear everything quite clearly and quite well. Certainly it sounded better than it does coming from my desktop speakers.

CD audio test: Well, now I have a vague idea of what it feels like to have two longshoremen kicking you simultaneously on each side of your head. This was tested with&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Scream-America/dp/B000Y80L84/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Scream America</a>&nbsp;played maximum volume, and now I think Germans might need to be held responsible for more crimes against humanity. (I kid! I like Tokio Hotel, but that was too good of a joke to pass up)

DVD test: This test was done using&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Smashing-Pumpkins-Greatest-Hits-Video-Collection/dp/B00005RFBA/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Smashing Pumpkins - Greatest Hits Video Collection</a>, specifically the video for "Tonight, Tonight", always a favorite. Everything sounded just dandy! I could hear parts of the music I hadn't heard before, which is always a nice thing.

Ultimately to me these sounded and performed well. I'm not a big-time audiophile, so I can't really compare them to anything else. I guess this is kind of like spending your life driving a 1972 Dodge pickup only to one day be upgraded to a Bugatti Veyron. You know it's better than what you've had before, but you don't know how much better it is than, say, a Hummer. Likewise, having gone from poor headphones all my life to these, I can say that they are better than $5 headphones, but I can't really say that they're that much better than headphones that cost $50 or $100.

So there you have it. Make of it what you will, I'm going back to listening to the Smashing Pumpkins and seeing how long it takes my eardrums to rupture.

Great sound. However, the headphones fit my head on the smallest setting. If you have a small head, it may not fit super well.

Vivid, life-like sound with HT-21 XBS headphones. Recommended.

My sons have Bose headphones many times the cost of this little wonder, and the sound in the Panasonic is comparable.  Here are the positives: there is little or no buzz, the noise cancelling seems to work well, I like the separate volume control on the device, and the upper and mid ranges sound great.  Here are the negatives, the cord is too short and the bass sounds somewhat weak, compared to over-the-ear Bose headphones.  On the latter problem, the size of the silicone ear buds matters quite a bit particularly for bass perception.  It was good that they included three different sizes in the product.  The largest size silicon bud had a noticeably better bass response in my ear than the medium sized one.

So I waited when these will go on sale and finally got them. The sound is very good. Padding is little stiff so I replaced them with HM5 earpads. The cable is superlong which is inconvenient. They feel very cheap too. So if you only have 10 dol - then get these. But otherwise - look at these - monoprice 8323, AKG K550-553, Audiotechnica M40x... Still - these headphones are worth the hype.

I hope I get to expand this review later when I have used these more.
I have listened to two songs on my computer wearing these headphones, and with the volume down so low it is almost to mute. Still the music booms out in clarity, power and excitement.
I am sold completely. No complaints; no misgivings.
Yay Bose!

As a hair-shirt Sennheiser HD 600 partisan/fan, my first impression was that, out of the box, the K701 sounded a bit more "hi-fi" and treble-intensive than I was expecting. (This will apply doubly for HD 650 owners...) It's a simple matter of adjustment, however. Give it an hour (I'll leave "break-in" discussions to others) and these cans make their case, in spades. After playing a couple of dozen songs I know inside-out, I'm sold. The sound is dry and caffeinated rather than warm or bloated, but the soundstage is huge. As in horizon-to-horizon huge. Music presents as out-there, as with speakers, not IN yout head. Also, if you are a bass-head, look elsewhere. These present accurate bass, not temple-thumping sludge. The fuzzy-felt earcups are comfortable and enveloping -- the comfort food of audiophile skull caressing. Listen to these for a couple of hours and they will win your cynical a-- over, one song at a time. Are they the ultimate truth? No. Nothing is, no matter if you chase that with $225 or $5,000. But their run at musical truth is endearing and valid.

Good value, paired with Denon AVR-S510BT receiver and Polk Audio PSW10 10-inch powered sub.  Music sounds terrific, TV sound good, movies very good.  Only caution- pay attention to the dimensions, because these are bigger than you think.  I had planned to replace ceiling-mounted 'surround sound in a box' speakers front and rear, but the fronts are now wall mounted next to the TV because they looked pretty silly given their large size.  As long as you note the dimensions and they work in your space, I think you'd be hard pressed to find a better value for a mid-range home theatre.

These are fantastic-sounding headphones.

I once worked for a certain popular computer company and have had the opportunity to test a wide variety of earphones, earbuds and headphones, but few have impressed me as much as the Beats.

BUILD QUALITY/OVERALL IMPRESSIONS:

While I believe the price is a bit inflated (we are talking about Monster, after all) the quality is spot-on. I've had mine for a couple of months now and have not seen any of the build quality issues some of the other comments have mentioned.

That said, I can see how they could be easily broken is mishandled. The plastic bridge (part that goes over your head) could break if twisted, and you should be careful when collapsing the earpieces to put them away. I believe that if you spend ~$300 on a pair of headphones, however, you should be careful with them!

The noise cancellation isn't outstanding -- Bose has that nailed, in my opinion -- so if you're looking for a pair to use on the plane, don't go with these to drown out the engines and cabin noise.

Sound leakage is my one nit-pick. They're plastic headphones that conform to your head and ears, so the earpieces themselves move, along with the extension for the size of your head. A bit more care could be placed on build regarding sealing the cups from leaking the sound. If you crank the volume up more than half-way or so, odds are that if you're in the library or some other quiet place, you'll be getting looks from anyone nearby.

Batteries (two "AAA" batteries) lasted me about 1.5 months of use 3-5 days per week for a few hours.

ACCESSORIES:

The included cable with in-line microphone and button works great. I love the design of the button and it feels rock-solid, easy to use even while wearing gloves. The mic seems to work fine and I have had no complaints of poor or weak sound quality.

They still include the standard red headphone cable, but I stick with the black one even if I'm not on my phone, as it draws a bit less attention. (As if the giant headphones with the "B" on them don't.)

They also include a pretty sturdy carrying case that has held up in my backpack and during my travels to and from school every day and on a couple of trips. They won't survive getting sat on or something, but it's a good case. The 1/4" adapter and cleaning cloth are also nice accessories to throw in. They all tuck away nicely inside the case.

SOUND QUALITY:

I'm no &uuml;ber-audiophile, but I love my music.

Use good files on a decent media player and you'll be fine. I can definitely tell when I'm listening to one of my older MP3s recorded at 128k versus a FLAC/ALAC or 320k+ file. They have decent bass, though not head-pounding, and excellent sound throughout the range, in my opinion, with no muddiness detected on my music, which encompasses a fairly wide variety of musical styles.

LAST COMMENTS:

I'd recommend these to anyone looking for a good set of headphones that doesn't mind the bulk that goes along with them. Don't get them if you're rough on your gear or if you're depending on excellent noise cancellation and no noise leakage. (As I said, despite the fact that they cup over your ears, sound does still leak. Sorry, Librarians of the world.) They're great-sounding headphones that made what I thought were great entry-level Etymotic earphones sound sub-par when I went back to them after a while. (For when I can't carry around these big headphones.)

These headphones sound great.  Nice bass response. Good range.  I listen to a diverse selection of music, and Vivaldi sounds every bit as good as Outkast on these cans.  The price is quite affordable, and the cord is plenty long enough to plug into a receiver and lounge on the couch while watching a Blu-ray or listening to your favorite album.

The only drawback is that I feel like I've fitted a vise onto my head and turned the screw when I put them on.  At first I thought that I could deal with the clamping sensation over time, but after being brutally pinched for about half an hour, I discovered that wasn't the case.  The earpads are somewhat small, as well, and don't easily fit over the average ear.  This compounds the problem as the cartilage is slowly ground into putty against the unyielding cranium.  In case you were wondering, I do not have an overlarge head.  In fact, as a child I was often mocked for my rather diminutive dome.  But I digress.  I found a "solution", however.  I simply detach the earpads from the solid plastic head band and affix the head band around one of my wife's large ceramic vases (she's a potter).  I found one that has a larger circumference than my skull by a few inches, and I let the plastic stretch out while I am at work.  When I arrive home to my abode, I reattach the earpads, and viola! The headphones fit comfortably.

There is, of course, the danger of stretching the band too far, thereby losing all grip, so one should not use a vase that surpasses one's head size by much.  So, there you have it, an inelegant solution to a pressing problem.  No pun intended.  Unless you have a small head or ears made of granite, I'd look for a more comfortable pair of headphones that don't threaten to squeeze your melon into a coiffured wafer.  For $25, though, it may be worth the gamble (and the ensuing stretch routine if you lose...).

I really like these Bose speakers. I use them for my home theater as well as for listening to music, and the sound coming out of them is rich, warm, clean, and loud, especially considering their small size. I'm powering them with a Sony STR-DH100 receiver which I bought for $130 on Amazon, and I believe this is a good pairing. At the current price, these are also excellent value, which is a odd thing to be saying about a Bose product, as they are generally known for being over priced.

There are only two caveats to mention. First, the cube speakers sound very directional, so you really need to be in front of them to get the full effect.  Secondly, while this system produces a very warm sound, it doesn't do a great job with deep base because the sub-woofer is just too small to hit those lows, and on top of that, it doesn't have its own amp. What this means practically, is that playing songs by the Beatles, or Green Day is going to sound great...but playing something from Bone Thugs in Harmony will sound a bit muted.

One more thing to say. I've had the small cube speakers by my TV for a few years, with the sub-woofer in a corner nearby. My fiance, who's lived with me the whole time, recently found the box (the sub-woofer) sitting in the corner and said, "what's this box doing here, can we throw it out, or move it to a closet?". Funny, but I guess it speaks to the small profile that the system has in your home. She just assumed it was only the two small cube speakers.

Favorably impressed with the big sound from this small package. Easy to use. Surprising bass response for such a small cabinet. Stereo separation isn't great, but for limited spaces, this is a good compromise. Love mine.

These are great headphones.

They come with a good case and everything needed, cable-wise, except for a charging plug, which isn't exactly hard to find nor expensive.  Charge times seem a little long to me (3 or 4 hours), but then the charge will last through many hours of use.

Sound quality is excellent.  Plenty enough bass, but not bass-heavy--I'm not a fan of bass-heavy sound anyway.

Noise cancellation is very good.  I can't compare to the Bose's since I've not used them, but I'd bet these are about as good.  Noise cancellation doesn't block all outside sounds (and it never will because, if nothing else, your body will itself transmit some sounds), but when playing music/video especially, you'll really appreciate how much isolation it provides.

The headphones are very comfortable on the ears and can be worn for hours... though your ears will get a little warm.

The controls are okay.  The touch pad can sometimes be triggered accidentally if you're laying down or put your hands behind your head, but not a big problem.  Remembering and properly performing all of the taps, double taps, slides, hold taps, etc. etc. etc., however, is sometimes more challenging than I'd like--there is a lot of functionality tied up in that touch pad.

Bluetooth connects easily enough.  Supposedly can keep up with several devices and will connect with two devices at once... though it won't play from both connections simultaneously--one or the other will play--and depending upon what's connected and playing, it may not switch well between the two.  However, this is a limitation of the Bluetooth standard, not the headphones themselves.

Downloadable app for sound customization and turning on/off a couple of features is meh... not as user-friendly as it could be... sorta confusing actually.

All in all, if you can get them at a Black Friday discount, I highly recommend.  At the full $400 price... hmm... not sure any headphones are really worth that much.

Great sound in an insanely little package. I wanted something portable but I am picky about sound. This thing is tiny but the sound quality and volume blew me away. It's great in its own but I bought the FoxLo to add bass and depth and it's a really sweet combo. I keep the FoxLo at work and bring the Dash7 along with me for home/travel or wherever.
I love it.
Considered JBL, and Bose but I'm glad I ended up with this one. Sound is really impressive and very clear. Will buy a red one for the wife when she gets her new position and has to travel.

It's no Bose, but for the money, I was pleasantly pleased with the quality of sound this little guy has. I bought it for the shower, but was so impressed that I took it with us to a sledding party.  We were outside in the cold and snow but it played like a champ for the entire 8+ hours we were out. Still had plenty of charge left. Because it is so small and "pack-able";  I am Looking forward to taking it on my outdoor journeys this summer.
