Monoprice 8320 IEM


Pros: Great sound, once broken in the mids are very clear.

Cons: You need to burn in these headphones, otherwise they sound flat.

I bought my first set of 8320 two years or more back. They were very flat in the beggining then someone sugested these should be burned in for a few days with white noise. An old cell phone and white noise generator helped break these things in. Man o man what a difference. Made my bose IEM look like dollar store headphones. Sound is a relative thing IMHO just like taste in food. Some like certain foods more or less. I stopped buying other types of IEM's. Simply put these are the most durable IEM's I have ever had, once you perform some choice upgrades they can be awesome.


I wore these for more than 2 years daily for at least 3 hours a day. They have never let me down.


My suggestions would be as follows.


1 - Get some better tips for these.

2 - Get a set of earplugs and cut them short and puch out a hole in them. Put them behind the tips for extra spring.

3 - do not forget to wrap the cable behind your ear to reduce microphoning of the cable. (Helps tremendously)


I even designed a 3d printable holder for these so you can store them in style. Here is a link. -> https://www.youmagine.com/designs/monoprice-8320-headphone-holder


I Even bought two more pairs to keep as spares as these after 2+ years are looking raged, but they are still 100% functional. If I bought 10 pairs I could have a lifetime supply of these. 




Pros: Great sound, clarity and price of item

Cons: Tangle prone cord

I read reviews on this and I said let me try this out, for $10 I couldn't lose. This surpassed all of expectations for a $10 IEM.


I am going to purchase a set for my wife, she was also blown away by the sound.


Pros: Unheard of sound quality and build quality at its price

Cons: Not the most isolating IEMs.

Allow me to preface this by saying that I have way more experience with headphones. The only IEMs I've ever owned before this were some cheapie $20 Sony IEMs, the MeElec CW31s, and the MeElect M9-BK. I've sold every IEM I've owned before this one, mostly because I felt like they never got any head time compared to my full-sized cans.


The packaging for the 8320 was about was minimalist as you can get -- there were the IEMs with inserts already on, no alternative inserts, no box, just a small plastic bag. 


The design felt pretty solid, especially for a headphone of its price. The clothed cable was a nice touch and felt like a definite step up over typical cables for low end earbuds and IEMs, but it did feel cheap. I did find that they very often got tangled. I'm actually very impressed with the durability of the cable so far. I've already accidentally hard slammed the car door on this cable, pulling the Monoprices out of my pocket with such force that one of the tips flew off and they still worked perfectly afterwards.  


The comfort could be better, but I'm not a giant fan of cheap IEM comfort. The lack of additional, different sized inserts is somewhat annoying, but they're also $7. The comfort is acceptable, but not something I'd want to wear all day. 


As for the sound, the bass is tight and punchy. The sub-bass isn't quite that extended and you get the typical dynamic driver drop-off at the sub-bass frequencies. Bass had a solid amount of impact, but the rumble made bass-heavy electronic music feel a little lacking. Overall, though, I found the bass response to be solid. The mids had a surprising amount of clarity. By no means was it crystal clear, but it was better than I remembered my CW31s. Overall, the details in the mids and highs was solid.


For the price, I give the Monoprice 8320s my highest praise. They're certainly not hi-fi audio, but they're absolute monsters in their price range. Most $7 earphones sound and feel like absolute crap, but these could definitely compete with the $20-40 MeElecs. 



Pros: None

Cons: Cheaply made, gaudy looking, terrible sounding

I got some of these based on their crazy-good reputation. Even for the $6 I paid I feel ripped off. Worst pair I can remember. What in the world is everyone talking about? These are so gaudy looking, and feel cheaply put together. I could overlook those things if they sounded like everyone says. But they don't. I can't remember disliking the sound quality of an IEM this much. These are just awful. I feel like I am in a Twlight Zone with these things. Their reputation can't be real. No amount of "breaking in" will fix this garbage. They were six dollars, and sound like one dollar. 


Pros: Sounds like Hi-Fi IEM Tight bass, great instrument separation (even for $30-50 IEM) Very Detailed Highs, very fast

Cons: FIT IS HORRIBLE very boring mids

Just want to explain one thing. In my opinion, the reason this IEM is receiving so much praise is it really sound Hi-Fi  It somewhat has lots of elements an audiophile looks for such as speed, positioning, instrumental separation and a punchy but tight bass, thus, making it what we might consider the Cheapest Hi-Fi IEM which, in my opinion, does fit the name of the 8320. 


Warning  as far as my experience went, I would suggest you all leave the other monoprice products alone. I ordered 3 other IEM/earbuds and none of them was even able to touch the 8320's shadow, not even the one that was almost double the price of the 8320.


Pros: mids are fairly well detailed, especially for the price, headphone is also surprisingly detailed (and bright) which leads to significant fatigue.

Cons: Bass extension if rather low, you can hear it, however don't expect much visceral impact

I've been a headfi stalker for many, many years, joining when the ER4 and whatever Shure or UE equivalent were just accepted as king, in fact the single most expensive thing I ever bought was with my own money in high school was a pair of brand new ER4P's. With the exception of the custom UE10's, these were basically the most highly regarded IEM or even headphone/earphone, this side of an Orpheus at the time.


However this is the first time I've felt compelled to post a review as by and large I think my hearing has deteriorated (I became an attack helicopter pilot in the U.S. Army for several years, the combination of turbine engines are 5.56 just ruined my hearing, and as such I've generally been more attracted to bass centric headphones lately- but, for whatever reason, recently seem to have been regained my high frequency hearing or at least the appreciation of what I have left..


So why am I reviewing the Monoprice 8320? Well, they're absolutely terrible, at least without the right fit. I'd read an insane amount on amount on them but still bought them and they'd always sounded terrible to me, the other night my RHA T10i's failed on me again (not a well made headphone despite the looks) and I was left with either my 7506's which I couldn't find, earpods or the monoprices, so I grabbed the monoprices after already having them written them off as being terrible, despite trying 5 or 6 different tip combinations and...suddenly I found one that fit, sillicon earbuds that I think I actually got from jabra bluetooth earphones. 


For whatever reason they fit perfectly, even without  playing music playing the isolation was exceptional and this benefitted a very specific type of rock, mainly, low-fi recorded rock, a good example is Interpol, who despite having great music, seem to have initially terrible recordings on their first two albums. The Monoprices' strength seem to be in digging up enough detail and melodic mids to sound good but without being able to resolve the flaws. There's no doubt they sound terrible without the right fit but once you do get it, I honestly think it's one of the most enjoyable rock music IEMs I've ever had for lower-fi recordings..





Pros: Great clarity, looks interesting

Cons: Lack of bass, lots of microphonics, easy to tangle

Hey Head-fi,


The 8320 have a lot of hype, but there are several aspects of it that I can't help but dislike. However, if you can look past these issues then it's really a very nice IEM.


Here's my review:


To sum it up:

There's a surprising amount of clarity, though instrument separation isn't the best. I felt that there was a distinct lack of bass (this could possibly be attributed to an improper seal, though I was under the impression that they were sealed adequately.). Comfort is a bit of an issue, as the top of the 8320's dig into my ear a bit. Microphonics are strong with this one (and they leak more sound than would be expected), but the mids and highs are quite good for the price. Just don't expect too much from them...


I'd love any feedback that you have, and thanks for the inspiration!


Pros: Clear sound. Cheap.

Cons: No bass. Weak subs.

First off, I got the 9963's, because there were lots of comments about how it's the better deal.

Got these because of all the head-fi rave, but they sound mediocre to me at best. Honestly, I'm not audiophile, and my hearing has been getting noticeably worse as of late, but these sound no different from my beat up MDR-J10s. Could be just me, but I was really disappointed after all the hype. I felt NO punch from the bass, and the build quality is no different than those mdrs. The driver enclosure is big on me (and I have pretty average size ears), hurts because of the stupid sharp ridges on the outside (I'd file it down, if I cared more about it. I nearly tossed it though), and the cable really feels cheap.


I used the J10s for a longass time with no complaint and these sound really no better to me, but I guess I was just in search of something stronger. This wasn't it for me. I need to feel my bass, not this squeaky crap that hurts my ears.


Went ahead and dropped 6x the money for a proper IEM ...


Pros: Sound can be excellent, depending on the source. Price is the best value to be found.

Cons: Fit and seal can be difficult. Cord is kind of strange, looks GREAT but is actually kind of stiff and kinky. Needs a neck slider.

I bought these cheap 'phones because of all the hype I saw on Head-Fi. The hype is so well deserved that I registered to Head-Fi just to add my weight behind these earphones!

I use these on my Sansa Fuze+ player and they sound absolutely excellent! With a good seal, which admittedly is difficult to get, the base can rattle your eyeballs....... NO KIDDING...... I was amazed.


My gold standard for "phones is the Koss Porta-Pro, And the various formats using that same drivers. On my Sansa Fuze+ the Porta Pros sound BREATHTAKING.... But I actually prefer the Monoprice over the Porta-Pros. There is an over-all pleasing and satisfying quality to these "phones that is difficult to explain. The sound is different than the Koss, Since the Koss are PERFECT, this would indicate that the Monoprice is inferior. Even so I consistently reach for the Monoprice and am extremely satisfied with the sound.  They are more efficient that the Porta Pros Too.


Now to be fair I also own a Sangean DT_400W pocket radio. This is a VERY high quality radio and the sound is WONDERFUL in headphones........ Except these Monoprice 6320s sound harsh and middy with that radio. The sangean's BassBoost switch only adds boominess to the mix. I would love to love the Monoprice on that platform also....... But no, the Porta Pros are the only way to go there.


For the $8 you just can't beat these "phones! My Koss cost $35 ON CLOSE OUT SALE, yet the Monoprice are every bit the equal on some platforms such as the Sansa player. The Monoprice will take amplification to the point of pain, in spite of the better efficiency...... I just don't have amp enough to make these drivers clack bottom. I can overdrive the Koss with the same amp.


If you don't like these 'phones then you didn't get a good seal..... Or your device just doesn't drive them well. The good reviews are ten to one against the bad ones. Buy some Monoprice, They are excellent. If you don't think so, just save them. Another platform will show them to be the (ugly) little jewels that they are! 


UPDATE! -  2/19/16    It's approaching two years since I reviewed the Monoprice 8320 . I am listening to them right now. The cord is all kinked and crinkly, The inside wires are poking through the fabric in tiny loops here and there. They are sporting triple flange MEE Audio tips now, for a quick and reliable seal. Looking rough and sounding WONDERFUL, they are in daily use and still going strong.


Mike Oldfield's Tubular Bells........... That low organ pedal note just rumbles, a note nonexistent and not reproduced when listening with full size speakers by the way.  Freakishly clean tinkling highs...... Well...... Just like the ringing of bells! Let's not neglect Pink Floyd's Dark Side Of The Moon............ The heartbeat, WHUMP-BUMP.....WHUMP-BUMP.....WHUMP-BUMP, gives chills and goose bumps. The clear and pristine voice of the torch singer on The Great Gig In The Sky brings tears and you don't know why. The clinking of coins onto a table so accurate that you instinctively check your pockets for spilling change. Can you tell that I really love these earphones? The best $8 ever spent! Still going strong what, 20 months later? You can't beat that.


Pros: better than the average iem that i got with my Cowon D20 and C2

Cons: For the price none reallly

Bought these just to see if the hype was justified, and yeah I think it is...
