Look Elsewhere - Minimal Bass!
931030
There's no bass!  I bought this product based on the Cambridge name.  I work in music and understand that in a small speaker, you're not going to get booming bass sound.  That said, there is no discernable bass at all from this speaker.

If you want it for listening to talk radio or non-music podcasts, it's fine.  If you want a speaker to enjoy music, look elsewhere.

I bought these headphones based on these very positive reviews, but I was rather disappointed. There is an unbalanced sound - very high/loud treble & mids, and basically a non-existant  "super enhanced bass sound." You can tell decent headphones by how much they bother/hurt your ears after listening for an extended period. These start to become uncomfortable after an hour. I was expecting something similar to Apples earbuds, but its not even close to their comfort & sound quality. I guess you can't go wrong for $10 headphones, but I was expecting something much better.

On paper, these seemed like the perfect speakers for me. The A2's always had rave reviews and the newly added built in USB DAC is a very nice update. I ordered these right away and was fairly certain these would be keepers due to all the great reviews. Well, that wasn't the case. Yes, the built quality and and highs are very clear, but I absolutely hated how directional and tiny sounding these speakers are. I bought the matching DS1 stands to angle these up at ear level and no matter how I placed them they always just sounded tiny. They are super sensitive on placement so the listening sweetspot is very very narrow. People are always saying how great the bass is on these speakers, and to a certain extent they are right. For the size of the speakers, the bass is pretty good, but honestly it is nowhere near enough to be acceptable in my opinion. It is understandable since you can only do so much with a 2.75" woofer. Overall, the A2+ sounded tiny, way too directional and sorely lacked in bass.

PROS:
build in USB DAC, excellent build quality, beautiful gloss white exterior, clear highs, auto off/standby feature

CONS:
VERY directional, "TINY" sounding, VERY weak real bass overall, heavily EQ'd sound (midbass boost), angled stands required, crappy copper clad aluminum speakers wires

I bought these because the price was great but I was disappointed.  There is definitely too much bass and not much else.  The sound is all highs and lows.  Adjusting the graphic equalizer on the player(software) can't completely fix it.  I bought the Creative T3000s to compare and they are noticeably better.  I returned the Logitechs.

I bought a pair of Mythos Two speakers to replace an old pair of PSB Alpha A/Vs that I use for watching TVs and listening to music.  After 30-50 hours of breaking-in, I can tell you that there's the POTENTIAL for some really good sound here, but by themselves, the Mythos Two speakers will leave you disappointed.

The crux of the problem is that these things have no bass.  The specs say they go down to 35Hz, but they're not even close...my Alphas go down to 65Hz, and they definitely have much more bass than these.  I'd love to get a meter on these things to see just how low they go...maybe 100Hz if you're lucky.  I've heard that DefTech is a little "optimistic" with their frequency numbers, and these speakers are definitely proof of that.

However, mids do sound pretty good.  Vocals can jump out at you with surprising realism...while working on other things, I was twice startled by how real a voice in a song sounded.  The highs are pretty decent as well.  There's...just...no...bass.

I mounted them to the wall on either side of my TV.  The included brackets are sturdy, but actually attaching the speakers to them was a nightmare.  There are two keyholes on the bracket that the speakers attach to, and a number of padded metal "fingers" protruding from the edges of the bracket to stabilize the speakers.  Two stopped screws attach to the back of the speakers, and they slide into the keyholes.  As designed, I could NOT get the speakers to mount...they simply wouldn't go into the keyholes.  Ended up loosening the screws on the back of the speakers, and pounding down the fingers a bit with a hammer before the speakers would mount, and even then it was a very tight fit.

In any case, I'll be shopping around for a sub, and will update my review accordingly.

The sound is terrible: quite tinny and voices in particular constantly resonate (around .8kHz), even at low volumes. Also clearly has an EQ which emphasizes bass range, while I had expected a flat frequency response. Fold down to mono is also quite poor, especially with audio that was originally 5.1 or higher.

Bought these after a couple years missing my older model of the Crushers (purchased ~2008, cable finally frayed and gave out in 2014). I am sorely disappointed in the reduction in bass. The old pair would SHAKE on my head, delivering powerful low-end, but also offered control granular enough to avoid overpowering the rest of the audio. These barely have different settings, the bass is basically on or off--and when it is "on" it is weak. Not only that, but the bass boost seems inconstant and spotty; Every once in a while there is a specific note strong enough to trigger a big push of bass, which then seems out of place with the whole rest of the mix.

The only pros I can think of are the improved housing/shape and the fact that the cable can be disconnected with any 1/8" aux chord.

It's hard enough to buy an item where 'fit' is so important to comfort... but these headphones, while they fit okay, have such substandard sound that it's really surprising.  At all but the very, very lowest settings, there is a vibration, a crackle or buzz, or distortion that makes listening an impossibly annoying  experience.  LOOK FOR SOMETHING ELSE!  While the prices isn't he highest, or lowest, I have had $1.00 ear buds that sounded like this, so I expected better, particularly from a brand name manufacturer.

I had high hopes for these headphones because I love bass. But I shouldn't have to give up clarity and detail in the mids and highs just because there's more boom, and that's where these cans EPIC FAIL. Lost tones can be re-introduced with some EQ boost, but not all devices have EQ.

These headphones are a contradiction of design: with the L-shaped mini-phone plug (and no 1/4" adapter), and short, flat cord it's clear these are targeted for use with mp3 players and other portable devices. Yet they're enormous and it would be somewhat of a nuisance to carry them around. I would rather use smaller cans or some buds with those kinds of devices, and in fact, some earbuds I've tried have better overall sound than these!

I tried these because the earpads are super squashy and comfy and I like to listen while laying down, sometimes I nap with music playing. For that purpose these are great, although they did make my ears hot. The short cord was barely able to reach from shelf to bed or computer chair even with my usual extension, and the L-shaped plug makes it even worse.

I think a better choice would be the smaller, lower-priced XB300s, because the sound quality is so close, and they also have very squashy earpads.

Speakers sound good.  A good bit of bass for such small speakers. However, they have a high frequency buzz in them that I can't get rid of, and it's really annoying. It's there even with the volume turned down completely on the speakers and the computer. Plus, adjusting the color on the bass to max intensity makes the problem even worse.

I have moved all of my computer cables to try and find an offending source, no change. I installed a noise suppresion coil on the signal line, no change. I moved the speakers to different locations. No change. There is only so much I can do with the cable length. I have come to the conclusion that these speakers have little or no shielding from any outside interference.

It's a shame too, cause they look good. I really wanted to like these as they are short and fit under my dual monitor stand. But, no deal. I would NOT recommend these speakers based on the performance I have experienced.

These are useless without an equalizer unless all you like is bass. I have to push all the midrange and treble knobs to the max to get a full sound spectrum. very cheap plastic design. it looks almost like a toy. If you have a big head they will extend long enough to cover your ears. I only paid $15 for them and I feel like I paid too much. I like a lot of bass but not when it drowns out everything else

Probably the best way to describe these is that they're adequete enough for listing to voice and vocal recordings. But, avoid these if you want to listen to music, especially if it's for your computer. They have good enough treble, but the bass is almost nonexistant, unless you keep them firmly pressed against your ears with both hands, all the time.

I also tried these on a CD player and they sounded just like on the computer. I heard that Koss makes great headphones, but these aren't it. They're just a quick substitute for the cheap $10 ones you can pick up at any store. After 7 months of use, the earpads have gone flat, and they let most of the sound out in the process.

For those who like tech specs:  UR18

Frequency Response: 25-15,000 Hz
Impedance: 32 ohms
Sensitivity: 92 dB SPL/1mW
Distortion: < 0.3%
Cord: Straight, Dual Entry, 8ft

Most important spec is frequency response, because it can produce such a wide range of sounds,(like something with 5-30,000 Hz. But, as you can see, the range for these is narrower, and that means a certain "something" is mussing when you listen to your cherished music. It basically means that the sounds aren't as rich as something that has a wider range (5-30,000 Hz). I also like a good amount of bass in my music, so avoid these if you're looking for something along those lines.

The Bottom Line: YOU GET WHAT YOU PAY FOR.

I was really hoping I'd like these headphones, but here is why I don't.  Most importantly, the bass response is practically non-existent, even with the bass turned all the way up on the equalizer in my MP3 player.  And on top of that, the ear pieces fits horribly.  It's hard and unyielding, and when I place it in my ears properly, it barely fits in and has a tendency to slide out.  It actually fits much better upside down for my ears, which makes it look really goofy on my head. The bass response is a little better when I wear it upside down, but not much.  Very disappointed with the sound quality. On a positive note, it easy to pair up with my cell phone

I bought these because I saw excellent reviews from cnet and amazon.  I was looking forward to finally finding in ear headphones that could deliver bass (most seem to be terrible at this).  I put them on and after trying the different fitting sizes to ensure proper fit and sound, I have to say the bass is very loud and impressive for in ear headphones, and the fit is fairly comfortable.  Unfortunately, those are the only good qualities.  The rest of the sound spectrum is just horrible.  Highs just sound garbled and muddy, mids are far too loud, and overall everything just sounds muffled.  I tried playing them through my PC where I spent a considerable amount of time adjusting the graphic EQ, and eventually got them to almost sound tolerable, but even getting the right frequencies boosted it still sounded muddy across the spectrum.

These might sound decent to someone used to cheap in ear headphones that just wants to listen to hip hop or rap, but DO NOT buy these for sound quality.  I am going to try to return these.  If I can't I'll probably give them away.

Very disappointed in this product - NO BASS!  It does reproduce spoken voice loudly and clearly and the FM radio worked fine, but on music much less movies, NO BASS and therefore no drama and no impact.  One does not expect a compact unit like this to shake foundations but even at its maximum setting the so-called subwoofer played only very softly and did not go deep at all.  How other reviewers raved about powerful bass from this unit I simply do not understand.  I am returning it.

I really wanted to like these headphones, but it's shortcomings are too large to ignore. Before that though, here are the pros and cons.
Pros:
1. Excellent comfort. The headphones feel weightless and put a hardly noticeable pressure on the head or ears. It's honestly the best I've ever encountered.
2. Very detailed sound. The treble is in-depth, allowing very minute harmonies and sounds to be heard that would otherwise be dull, muted, or unheard.
3. Long cord.
Cons:
1. Absolutely terrible bass. And I mean terrible. Even acoustic songs, with simple drums and no trap or EDM influence, the bass bottoms out. The headphones can only register the higher treble range of the bass notes, leaving the bass raspy and grating. I was quickly disgusted with the sound when listening to any song with moderate to heavy bass.

Overall, these headphones have an interesting trade-off. On one hand, they're comfortable and have an astonishingly crisp treble sound. On the other hand, the bass is absolute garbage. I've never heard of headphones that perform in such a hot-cold way before.

I really, really wanted to like these.  I did a lot of research and was expecting a rich sound experience.  But after installing and listening to a variety of music, I was left disappointed.  They have great volume for small speakers and the highs and upper-mids were clear.  But the lower-mids and bass were barely there, even at a medium volume.  I eventually cranked it up full and was able to get a little more bass.  But not near what I expected from reading reviews and not in balance to the louder highs and mids.  I felt like the sub-woofer was just under-powered.  I bought these for an office environment and I can't have the speakers a full volume just to get some bass.  From a build standpoint, they seem sturdy and well made.  And they were easy to install.  But if you are looking for higher-quality sound for music, I'd suggest another product.  For home theater or basic gaming, these would probably be ok.
