Product Description

Product Description

With its stylish design Monoprice Enhanced Bass Hi-Fi Noise Isolating Earphone will prompt complete strangers to ask you where you got them, but you won't hear a word they say as you rock on down the highway. Made with a noise-isolating design and producing clear and solid sound, these earphone are a great way to enjoy your favourite music from your iPod or other portable music device. They fit comfortably into the ears and produce solid bass notes and clear midrange tones, both normally a weakness in earphones.

The 122 cm cord terminates in a gold-plated 3.5 mm stereo plug, which connects to most popular music devices and phones with better connectivity and corrosion resistance than the more common nickel and tin-plated connectors.

The end result is a pair of earphones that are made for the rigors of daily use from the music fan on the go. Amazing sound clarity, hard-rocking bass and durability. Specifications: Model Number: 9927;Driver Unit: 14.2 mm;Impedance: 32 ohms;Sensitivity: 96 +/- 3 dB / 1mW (S.P. L at 1 k Hz);Frequency Response: 20 Hz to 20 kHz;Rated Power: 3mW;Maximum Power: 10mW;Maximum Voltage: 1.23V;Cord Length: 48" (1225 mm);Ported: Yes.

I mean, she says they stay in well when she's at the gym or whatever. I think they came with 3 different sized buds/tips, and they are quite bright pink as the images suggest. Not amazing sound quality, but for the price you can't complain too much - they do have quite emphasised bass so if you prefer a more natural sound I'd suggest try elsewhere. She's not an audiophile :)

There is no benefit to the design of this product. The style forces the wire to drape uncomfortably over and behind the ear, whilst being too lightweight to drag it down. Subsequently it simply does not lie still anywhere on your face or head.
The earbud is large and uncomfortable to lie on, due to strange wire protuberance.
Also these will tie themselves into infuriatingly impossible knots constantly.
All in all, awful design. Choose a standard headphone for less trouble.
Good point: sound is fine.
Bad point: design and use.
Verdict: don't bother.

HASH(0x87b6ab1c) out of 5 stars Make this a 5 Star IEM, Just Add New Tips! 17 Aug. 2012
By Stumpy - Published on
Verified Purchase
First, lets just start with the Cons and get them over with.

- Worst stock tips ever. Monoprice MUST know this, but at $8-$11 price range and how many they sell, no reason for them to change this.

- Odd design. For some people they will just flat out not fit in your ears. For me, it feels like my ear was the original mold. They fit PERFECT (well except for the stock tips).

- Awful Microphonic Cable. Meaning, every time you move the stock cable, you are going to get noise in your ears. Best to sit still using these.

Ok, on to the Pros

*Note* - to get the best sound out of these you HAVE to get aftermarket tips or steal tips from other IEMs you have. Most would say this is enough of a reason to give the 8320 a bad review, but once past this SUPER easy fix, your world will be forever changed, by a $8 IEM.

- Once the ear tips are replace (*Update, I now use the Comply T-400 Tips) the overall Sound Quality will blow you away. Though, I have no idea why these are called "Enhanced Bass" IEMs. They are not bass heavy at all. They are bass neutral. You hear the music the way it was meant to be heard. Not too much bass, not too much Treble or Mids, but just the right amount of each.

- The sound that comes out of these is perfection at a super budget level. They should not sound this good. They should not cost this little. But they do. They really do.

Of course you do not have to believe me. Check out the Head-fi forums and read for yourself. The best trained ears in the world will tell you the same things about these IEMs.

I can see why people give these lower ratings. These are not ready to go right out of the box. They need tips, they need the right shaped ears and to be used when not moving at all. Though once all these requirements are filled, they are 5 STAR IEMS. For me, they are 5 Stars and More.

HASH(0x8801e3d8) out of 5 stars Very accurate sound, astonishing value! 8 Aug. 2012
By JPS - Published on
Verified Purchase
I recently purchased six different sets of earbuds/IEMs all under $100 (based on online recommendations), trying to find ones that have great sound and are durable.

My tests were consistent between the different sets. I have listened to the same familiar music tracks, and analyzed a swept sine-wave test tone (from 20Hz-20KHz) to compare the musical sound and frequency response. I am an experienced musician and audio engineer (though, my ears are showing some signs of age and "mileage").

What impresses me about the Monoprice 8320's is that they are quite flat and accurate across the whole audio spectrum, except for one noticeable hump around 8 KHz. The bass of the 8320 is a little understated, and won't be enough for folks who want moderately strong bass. However, the bass is adequate in relationship with the rest of the spectrum and showed no resonances at specific frequencies. It extends all the way down to 20 Hz. To my ear the 8320's have a sound is natural, clear, pleasant, uncolored and not "hyped".

It is possible that the reviewers who called these "tinny" might strongly prefer bass-heavy earbuds, may not have gotten a very good fit/seal, and/or may be referring to the bump around 8K. All but one of the earbuds I've tested had that extra presence at 8K-- perhaps that is typical?

For my ears, the 8320 are a little less snug fitting than any of the others I have. The shape of the driver prevents them from being inserted more deeply. It is important to keep the left distinct from the right because the tips are angled and won't fit well when reversed. I marked my right bud with a little red tape. They fit better in the ear if they are oriented so the "shark fin" is on top, and the cord comes out the top-front. Once rotated this way, it makes sense to run the cord up over the top and down the back of the ear. This makes it harder for them to get yanked out-- (don't you hate that?)

The isolation from outside sounds was minimal. This is actually preferable for some uses. For example, as I walk around and listen to podcasts & music, I want to hear some outside sounds. If I need more isolation, I use different buds. The 8320 does not come with replacement tips, however, the size is pretty standard so other earbud tips fit it (like M9 tips which can be ordered from meelectronics). Different tips might improve the seal and yield better sound (depending on your ear size/shape). However, changing the tips does not improve the isolation.

They have bulky, yet durable metal driver-housings and connector barrel. The build is solid and rugged. After a couple months of frequent use, they still work perfectly. At first, I liked the cloth-covered wire, that is very light and flexible (like string). But I quickly realized that the cord is VERY prone to kinks and tangling. You may have to come up with your own way to keep the cord free from tangles. I would have preferred a different type of cord for that reason.

The packaging could not be more minimal or environmentally sensitive: a little plastic baggy. Some of the other buds I ordered came in extravagant nested glossy boxes, with plastic trays, and multiple zippered vinyl pouches, etc.

The biggest surprise was how well these Monoprice 8320 earbuds compared to the other more expensive ones that I just purchased. They sound great, and are really nice for day-to-day use, and I am really pleased with them!

For the money, it's a no-brainer, IMHO. I just bought 3 more.

HASH(0x886a62f4) out of 5 stars The Definitive Guide (shamelessly) to rock out with the best 8 bucks you'll ever spend! 3 Dec. 2012
By Chi Zhang - Published on
Verified Purchase
Really not much to risk here, spend the 8 dollars, try them, if you like them great! If not, please follow these steps to troubleshoot:

1. Seal problem
Put them on, with the wires running down (not behind the ear), now gently tap on the wire at your jawbone's level, you should hear rather loud tap sound. This is bad generally but in this case it indicates that your seal is good. Another test is to wear the wire behind your ear, and tap on that same wire and you should hear a much quieter tap sound. If they sound about the same, your earpiece is not sealed. Then dig out any silicon or memory foam tips you may have from other earbuds, if not, I recommend this: Sony EPEX10A/BLK Hybrid Replacement Earbuds . Yes it's almost the same price as these headphones themselves but it'll be worth it. The fitting can be a bit tight, just push really hard and combine with rotating motion to get the fitting right (trying really hard to to keep a straight face)

2. Bass not powerful enough
After you're certain the seal is right, but still want more bass, this is what you do: find the little hole right beneath the earbud silicone piece, no not the pipe-like miracle-producing, there should be another small hole on the ear piece's body. Now find some clear tape, cut in to very small piece, and tape over that hole. Be sure the tape over the entire openning, now try them on again... BAM! (I personally find it too bass heavy this way sometimes, and I listen to quite a bit dubstep/D&B)

Overall, these little guys are great, especially for the price. I own several In-Ears including 400 dollar Shure se530, but this 8 dollar sound almost as good as my Shures. Believe me once you get past the seal problem, you would simply buy another 10 of these just to stock up since you love them so much. Also be sure to wire them with wires around your ear to reduce wire noise, and don't get too frustrated when the cable tangles and rip them apart. Don't get me wrong they look rather quality built, with fabric wires that make them look like $100 worth.

Monoprice should start their stores and sponsorship, cuz these headphones deserve BIG names and BIG recognition, but then the price might go up. My girlfriend just got her iphone 5 and was all like "wow the new iphone earbud looks sooo cool, and sound sooo great", i had to refit my Monoprice with the small-size Sony tips, but it was worth it, she tried them and was like "well when i save up I'll get these then, but the apple earbuds came free with the phone". Truth is the apple earbuds probably cost $50 to each iphone user, now that's 6 pairs of these Monoprice babies :)

Ignorance is bliss?

Now I also need an iphone 5 upgrade :)

(Feel free to ask questions, I'll be happy to help you get the most out of these Monoprice, they are like pec muscles that can lift 400 lbs - sooo easy to impress with)

HASH(0x87b6af48) out of 5 stars Modifications are required to make these sound good (subjective opinion of course) 4 April 2015
By Andrew - Published on
Verified Purchase
Rating: 2 stars out of box & 4 stars after modifying = 3 star average

Short review: If you want a cheap, comfortable pair of earphones that sound great out of the box and you don’t want to bother with using a graphic eq or modifying them, then I would pass on these. Spend a little more on something better (sorry, no recommendations).

Really long review: These are my first pair of IEM’s and I quickly discovered that I didn’t like them at all. The upper midrange is very shouty, the ridges on the housing cause extreme discomfort after about 20 minutes, and there were channel imbalance issues with the two pairs I bought. I would rate them 2 stars out of the box. However, after a bit of tinkering, I came up with a few modifications that made these much more enjoyable. I would rate them as a 4 after these changes. The rest of this review will cover these modifications.

First, sanding down the ridges on the housing makes these much more comfortable. I can wear them for long periods of time now. I used a measurement microphone to measure the raw frequency response for these. In the picture posted, the red and blue lines are the left and right channels (respectively) of the 9963’s. The graph looked exactly how these things sounded… terrible. Huge +10db peak at around 4 kHz (most sensitive range to our ears btw), rolled off bass below 200 Hz, and a dip in the upper treble from about 8- 14 kHz. Crash cymbals, female vocals, and electric guitars sound very harsh as a result. This, combined with the anemic bass and channel imbalance, created a very unpleasant listening experience. You can see the channel imbalance between the left and right channels below 1000 Hz.

Using Equilizer APO on my computer, I created two simple filters that dramatically improve the balance of the sound (30-18k hz @ +- 5db). Using one peak filter of -10db at 4000hz (Q 1.0) and another -3db PK at 2000hz (Q 1.0) was all that was required to tame the harshness. If you have a rockboxed sansa clip, applying these settings under the simple eq menu will provide similar results. The headphones will become much less efficient after these filters are applied so you will have to increase the volume further to reach the same spl as before. Also, I found out placing a piece of electrical tape over the little hole on the housing increased the low midrange and bass response below 1000 Hz (second picture – blue line to yellow). Warning though, long term, this may damage the driver membrane since there is nowhere for air pressure to escape from the housing.

After the mods, these have a warm, balanced sound signature to my ears. I rate these 4 stars after mods since you will not find another earphone that performs this well for $9. Keep in mind that although the frequency response measures fairly flat, they still don’t offer the transient response or imaging capability anywhere close to a pair of studio monitors or high quality headphones (not that I would expect them to anyway). Just pointing out that pretty frequency response graphs aren't everything.

Final word: Save the hassle and buy better headphones.

HASH(0x87b6d114) out of 5 stars Great earbuds regardless of price 28 Sept. 2013
By T2000KW - Published on
First, as I approach 58 yeas of age, even taking care to wear hearing protection in industrial environments, let me just say that I no longer have golden ears. However, I've read many reviews by self-proclaimed audiophiles that indicate that they don't know what they are talking about. (Some do, of course.) I used to sell stereo equipment back in the heyday of 4-channel sound and was able to listen to all sorts of great sound toys, including electrostatic headphones (which are still too expensive for most of us but the technology gives you great sound!), so even with some hearing loss, I can appreciate good sound.

However, even at my age, I still can tell what sounds natural and what doesn't to my ears, and these sound great. I have some $100 Kicker headphones that don't compare to these inexpensive earbuds. As some reviewers have claimed, these are not bass-enhanced at all. They have a neutral bass sound. The midrange comes out very natural and not pronounced, and even the high end does not sound even a bit on the brassy side. Nothing stands out (and nothing really should!) except the natural sound across the entire sound spectrum.

I'm not taking mine apart, but I suspect from the size of the larger part of the earbud case that these have larger drivers than what most earbuds have in them, which could make it better for reproducing bass frequencies, but it doesn't make them have a boomy quality to the sound.

Many complain about the tips not fitting well or not isolating well enough for them. I find them to work fine with the stock tips that come installed on them. They fit my ears very well. I like not having complete isolation so that I can have some idea of what's going on around me. But if you need better isolation, consider the Comply T-400 Tips sold here. Those cost more than what I paid for the earbuds direct from the manufacturer, but if you want more isolation or a better fit, then they might be an option. You'll still have better sounding earbuds than those costing many times more.

I did notice at first that the cloth-covered wiring will make a sound you can hear but if you're not moving around much, it shouldn't bother you. If it does, get yourself some inexpensive earbud wiring clips (I bought some 5 for $0.99 on a large online auction site) to clip the wire to your shirt and keep that from happening.

You can't go wrong for the price with these earbuds.
