Invisible touch of bass that kicks....

Before I get to the review of this lovely sub, I'd like to thank amazon customer service and CS supervisor (D.) for making UPS to do their job and not just drive by my house with the package I paid for, but givin it to me as well.

I am not really a audiophile, but I am getting to it. This sub is probably the best sub I ever heard and it's... well... if not ideal for true true music listening - it's very dmn good and sure sounds ideal enough for music to me. I have it paired with TSi500 biwired to SONY SSCS5(6 ohm, but give awesome mids and highs) and Yamaha r-s300 receiver. I decided to replace my one year old Bic F-12 (wasn't so bad) but there is a difference. Big difference. I am seriously considering to get one more unit (it's discontinued for some reason).

Perfect fit, but I was let down with the bass.  It doesn't hit at all.  I tried all the radio settings and settings on the module itself, no thump.  Kinda like a woofer, not a subwoofer.

While you're playing something there is not problem and they sound good, otherwise there is a buzzing sound. It is not the AUX cable. The same buzzing is there without the cable. :-( oh well.

When I first fired these up I was psyched... so much sound from two little boxes with exceptional bass! But after awhile of listening to various types of audio you will find that the highs are there, but they are overwhelmed and squashed down by the bass and lower midrange. So when you are listening to a voiceover let's say, the voice is behind the music and effects. I guess you would say that the wonderful "brightness" is missing. A little bit "tanky" and "muddy".

My question is this, how can a company make earbuds that sound nearly as good as bose ae2's at 1/5 the price?
The sound that comes from these babies is extraordinary. Bass that reaches sub sonic levels! You'll hear subtle parts of a song you never knew were there.
My barometer to test bass for headphones or speakers, is the song 10 candles by Boys II Men. This will push any headphones to the limit and show what they are made of. These ear buds shine here.
One really cool thing they have added to the design of these phones is a red colored earbud, to let you know which one is this right channel. For anyone who has used earbuds before, the left and right markings are not always easy to read.
Without a doubt worth 30 bucks! Makes you wonder what the high end moshi's sound like?

I like the fit of the band, but the headphones don't measure up.  For one thing, there's no bass.  The sound is very treble and very "tinny" and annoying as all get out.  The left speaker barely works; it puts out less than half the volume of the right, which mean there is no stereo effect at all.  I can only tell it's putting out sound when i flip the right one away from my ear, and then there's barely any sound even with the volume cranked up to the max.

WHAT. WHAT ON EARTH.

Absolutely incredible. The sensitivity of the high trebles and mids just UNBELIEVABLE. The bass is a tad bit muddy and on the softer side, but I'm a guy who enjoys a deep V-sound and strong bass anyway.

Absolutely incredible sound. You need to buy these at this cheaper price, before they realize what these IEM's are actually worth.

I have been a avid bass player for over 30 years and I need and wanted my ears bud to produce a rice low sound Feq. After trying very expensive sets of Sony and Shure buds my heart was won over by the V-Moda VIBE Buds.

They have all the bass I need but if you do try out these teeny tiny miracles you need to make sure your MP3 player or other player has a EQ. The VIBE buds need to be fine-tuned.

Now while riding my lawn mower, all I can say is WOW!

ROCK ON

Bass sound is not coming from my earphones. Can anyone suggest me if anyone can be done to improve the bass sound. Or my piece is a faulty one ?

Slight distortion on heavy bass music. Good baby for your buck though. Don't get this if bass it's a top concern

This sound bar is amazing.  The two subs however, are not.  They seem to play all sounds and not just lows.  I shouldn't be hearing words through the port in the subwoofer.  I've tried everything to get it to stop and can't figure it out.  So in my opinion, if you're looking for bass, look elsewhere.

EDIT

The support team worked with me and emailed me a custom update for my system that worked out for me.

I purchased these to replace a pair of isolation earbuds I got FREE when buying a certain product about 7 years ago. I can honestly say the free earbuds were FAR superior.

The sound is sharp, and they really do isolate almost all background noise. But the bass is almost nil, and that is a big issue for me. You have to turn the volume waaay up in order to get a half-way decent sound.

If you want a cheap pair of earbuds and don't really care about sound quality, these are for you....

I have had this for a couple of years now and I am a music enthusiast.  I replaced a wonderful JBL sub and speakers when I switched to Polk Audio.  I love the speakers but the week link in clearly in this sub.  It is simply lifeless, dull booming type base sound but most has certainly had no distortion.  However, if you get the volume beyond 120 it will produce a low volume hum.  I have small Yamaha sub, 6inch down firing for my TV sound system that truly out performs this sub by leaps and bounds - it has such clear deep tight base sound much like the JBL.  I am in the process of replacing this sub with a Yamaha.  I want a sub that will make sound exciting such as to feel the T-Rex in Jurasic Park running after the jeep simply come alive in the room as he takes every step and moves the ground beneath my feet with such excitement as if I were there!  Or listen to Led Zepplin as if you were in the concert yourself.  This sub does not do any of this for me.

The bass. It makes sense, really, that the bass is this good. Punchy. Tight. In your face. Or in your ears, actually.

But seriously. The bass. It's not overpowering, unless by overpowering you mean that it just sounds so good that you can't stop thinking about it. Everything else is good too. The mids, the highs, all is fluid and organic; crystal clear and life-like. But oh... the bass.

I read somewhere that durability might be an issue, not so. My pair looks solid, like they will be here for a good while. These are of a high quality build, comfortable and stylish. You will almost forget they are there. You just might almost forget that everything else is there too and slip away into a state of sonic bliss. Just you, and these amazing sounds.

At less than $100, these are a steal. I can't think of how many headphones I have listened to that I would consider inferior, all the while costing much more. You need these. Just one note: if I have ever had a pair of headphones that benefit from burning in, these would be the pair. It doesn't take long for these to really open up, but after burning in awhile there is a noticeable, positive change to the quality of sound.

I have a number of headphones to compare with, including Sennheiser DJ HD8 and Beyerdynamic DT 1350. Basically (no pun intended!) the bass on these Sony headphones is a bit too much. I do prefer headphones with good bass, and I listen to a lot of hard-hitting bass like Skrillex, other EBM, grunge rock and pop dance tracks. So it's not that I don't like bass - The problem with these Sony headphones is that the bass is just "too much". And this is before you press the "bass boost" button. Let's take Korn "did my time" for example: With the Sonys, the bass is definitely there, it's rumbling like thunder. At first you'd think wow, I found a great price alternative to Beats, these will be great! But then, switch to the Sennheiser HD8 DJ headphones, and the bass is much better; With the Senns, you can hear what the bass player is doing, like you can hear the bass guitar itself in detail - you're conscious of his finger movement within the driving bass. Back to the Sonys, and the bass is there, perhaps a little bit more so, but it's just "thunder". In Skrillex live 2015 Miami, with the Sonys, in a few places during the concert you start to think the sound engineer did something really wrong, like the bass beat is really in trouble and overwhelming the house audio, like it's about to go into feedback in  bad way; unstable. Then switch to the Senns, and right away the very same bass beat is a BEAT lying on a deep bed of bass and rhythm; all good. Granted, the Sennheiser HD8 is a more expensive pair by 2x, but it's a good way to analyze the bass in these Sonys because it lets you see that the Sony pair is using bass as a gimmick. I'd rather just tone down the bass a bit.

Edit / Addition: After about a week of use, I just couldn't take the thunder any more - it's too uncontrolled. So I worked out a fix: Stuff the insides with fiberglass strands. You first pry off the pads, remove 4 screws, drop the drivers out, remove 2 screws behind the driver and open the inner tray behind each driver. Easy. Then stuff in a few grams of fiberglass strands, pack it all back up. NOW these headphones rock@! The bass isn't breaking up any more, it's deep, nice, and tight.

The bass is as good as everyone says! I mostly listen to Dubstep/Electronica so I was interested in finding a pair of headphones with good bass response. These headphones have ear vibrating bass that sends chills down your spine and good rich sound after slight adjustments on the equalizer. Some of the bass is missing while paired wirelessly, which is to be expected, but sound like this along with Bluetooth capabilities, all for $45? These are a great deal. The build quality feels top notch and I love the rubberized red finish which is deep and metallic. My one complaint thus far is that they just barely fit my head. Someone with a larger head would have NO problem with these. I have a smaller head though, and at their smallest, they just barely fit my ears perfectly. Well, perfectly may have been about 1/4 inch shorter, actually. My coworkers all tried these on and had the same response - their eyes opened wide and their jaw dropped. "I've never heard bass that good in headphones!" - I know! I'm glad I purchased these! They're a GREAT deal. One coworker is planning on buying a pair for himself!

The highs are crystal clear and sound clean. If you're looking for bass also, there is none. So I'm not sure what people mean in other reviews saying this little thing has bass?  I bought two, I should have purchased one first then decided.  They sound good tho for the size. Would of given this unit 5 stars if it had some bass that sounded like actuall  bass. The little subs that move with the music put out a weird sound.
