Pros - Warm, bassy sound with upper mid airyness
Cons - Slightly on the harsh side, and lack of true detail
Dunu by Top-Sound is famous for good price to performance earbuds as well as the amount of accessories they include with their very well built units. Dunu introduces the Detonator as an earbud for phone users so that people can catch calls and talk. This earbud features a microphone with push function terminated by a V angled jack. Now let's see what Dunu has to offer this time
Read the review here:
These are some incredibly well built units. The earbud unit itself is literally a solid chunk of metal. They are heavy with 'authority'. Each wire termination into each other has plastic cuffs surrounding the wire to prevent wear and tear. The V jack, splitter, and wires to the buds show this quite well.
However, after the driver and safe guards against tear. This is quite a normal earbud for $50. The wires are thin and plastic wrapped. Skinny and mobile. The flexy/motion of the wire does have some kinks in it. It's not fully fluid like spahgetti, but it won't matter to most people. The splitter and chin adjuster also has some issues. The microphone blocks the chin adjuster from slidding all the way up to the chin itself. This won't let your fully secure it, but it does reduce some motion of the wire. The housing of the mic assembly is a bit light. Nothing especially noteworthy about it. It should also be noted that Dunu's in general also have some problems due to the 'weight of authority' they hold. They hit stuff hard if you drop them onto a table after you are done. This requires extra caution to not damage the unit or other things around it. One can usually just pull the earbuds out without worry. But with the Detonators, you have to watch out.
As this is an earbud, microphonics will be audible. However, due to the relative fluidity of the wire and heavy weight of the drives. The noise produced is quite negligable for most people and should not be a problem. Pulling up the chin slider to the highest position(right below the mic) will create even less cable swing and rub noise. You may also attempt to wear the earphones with an over ear style.
Isolation and Leak:
How well it isolates will largely depend on your fit with the unit. But I have had little to no problems with isolation or leak. The heavy material used and sheer amounts of tips that Dunu provides do allow for a good fit on most people. Of course this is when music is playing. Leak is not all that much of a problem either due to the narrow tip design and the material used as well.
Dunu bundles a new indented medium hard fabric case with the DN22M. This allows for easy storage and usage from your pocket. The relative fluidity of the wire (and it being lightweight) with the compact driver sizes do allow for quite easy usability. Take it out and put it into your ears. However two things must be noted. The weight of the drivers themselves do pose a problem when falling out or being taken off as they will come down with force. And, I myself can not get a perfect sonic fit. The left driver no matter what will still produce more bass than the right.It may be the driver or it may be me. My ears are quite different on the inside.
- will add quote-
So if you read enough, you will note that how the jacks are on the DN 22M will matter depending on what you want to use it with. As this may cause some problems with audio playback or even mic usage. The DN 22M works with the format Apple (and most of the world now) is using so this is good news. However if you do get problems, just note what you may have as an issue.
The DN 22M boasts quite a good mic. I was quite surprised when I tested and heard it. Background noise isolation is above average and my noise was nice and clear. However this was a local recorded test. Talking on the phone will achieve different results as the audio will be heavilly compressed and sent.
I am quite surprised by Dunu's mic on the DN 22M. This was tested with iPhone 4S.
These do not need to have an amp. If you wish to use one, go on ahead but they do not require one for more quality. Please keep in mind that if you wish to use an amp, the microphone function will not work as you are now plugging directly into a only 2 channel amp(unless the amp has mic support which is unlikely).
These are efficent enough to not need an amp.
Sound Quality Introductions:
I went into the DN 22M with varried thoughts on how it might perform. Hearing it these past weeks have put me at rest that Dunu is working on many issues I have found with their past products of the price range.
This is really the problem section of the DN 22M. This and the upper mid range(which can be said to be close to the same thing as the problem here leaks to there) are really the problems of the DN 22M but they are not by far killers. Dunu's past units and many other manufactuer's at this price range typically have two qualities to their high freq range. Piercingly harsh or subdued to the point that it can't even be said to be audible. Dunu's like to go with the first route. The DN 17's(version 1) had some extreme issues with the high frequencies, and the DN 22M's do as well but they have been fixed in some ways. The highs still pierce and have no quality to them. Good highs will actually be musical representations still, bad highs that are visible here are just a burst of high frequency sound. This is what is here on the DN 22M (as well as on most units in the price range). They are sharp yes, but hold no value to music or sonic reproduction. The DN 22M's however do hold a big advantage. They are not nearly as harsh and fatiguing. This of course depends on the song you are listening to, some don't really get into the high range as much which is a huge positive for the Detonator, but for those that do, it will be a negative(but not nearly as big). Anyway, the DN 22M's highs while piercing, are still much smoother than the highs of most units I've heard at this price range. The highs produced with the DN 22M don't have any real musical repdroduction ability, but don't 'scatter' around and lead to more harshness as usual. A good sign out of a range of bad ones.
The upper mid range freq get similar problems as the highs. After a few hours of burn in, they have subsided. The upper mid has a spike. This makes cymbals and other instruments at that range sharp. They are not like the high range where they lack any reproduction ability, they still have articulation and 'actual sounds' comming out. But they do get a bit hard to listen to after a bit depending on the songs. The regular mid instruments are pulled back. They aren't forward and take a side role from the vocals usually. They are about as loud yes, but that isn't what forward role or backwards one is. The mid instruments are not the center of attention. The vocals are laid back and have a veil on them. Not bright and outgoing, but a bit laid back with the lack of a mid to top vocal sparkle that really brings it to life. The articulation of the vocals thus do sufer a bit. The mids would actually be fantastic if the highs and upper mids were cleaned up from their issues. The mids get their own space and rarely get intrusions/leaking from the other frequencies. High frequency bursts do get in the way of them sometimes though, but its more of the highs being louder than actual leaking and muddying of the highs.
The DN 22M's are definately a more bassy earphone, but not as bassy as a non dampened DN 19 and DN 17. The DN 22M provides a good amount of sub, and mid bass to go along with songs just enough without going over. Not really for bass heads (the highs will scare them away anyway), but for people wanting a more balanced sound. The sub bass production on these is quite nice. They do have weight that is usually absent from earbuds of this price point. The mid bass also goes along well with many songs. Sometimes it gives a nice rush and bump while other times, it is barely noticeable. It doesn't muddy the mids.
(keep in mind that the left ear is getting more bass than the right, I am using the left ears as the one for the 'more bass')
The DN 22-M's don't exactly have a wide sound-stage, it is more of a closed sound. They do have the ability to aritificially create one well as I have seen with my test tracks, but on their own, they don't have much to say about the soundstage.
The highs and upper mids will lead to fatigue after a while, much better than the DN 17 V1 though.
The DN 22M for $50 is definately proof that Dunu is stepping up their game. I really dig the vocals on these. If it wasn't for the problems with the highs and upper mids, I would really dig these. It is warm and fun sounding boasting a balanced sound(for the price). It doesn't over accentuate any of the frequencies, they just do their parts. The good microphone adds even more claim to Dunu's ability to listen and improve upon their units. The DN 22M's does have many draw backs, but it also includes some good value for the balanced sound it gives and the microphone.

DUNU Detonator DN-22m Quick Review
Thanks to DUNU for the sample.
Full review http://www.head-fi.org/t/666628/dunu-detonator-dn-22m-review
Brief: A well timed, bassy fun machine.
Price: £37.61 or circa the RRP or US$45
Specification: Driver Size: 9mm, Microphone: -45 +5dB, Sound pressure level: 112+-2dB, F Response: 20Hz - 20KHz, Noise Attenuation: 26dB, Weight: 27g, Cord: 1.2m
Accessories: 8 pairs of tips, shirt clip, a hard case and a soft baggy and a built in cable tie.
Build Quality: Top class, really just top class given the cost. Easily the equal of the far more expensive EB-50.
Isolation: Very good for a dynamic, plenty enough to get you through normal day to day stuff and maybe the odd flight. Certainly enough to get you run over if you aren’t looking where you’re going.
Comfort/Fit: Pretty great, worn down the mic did catch my collar which is annoying but that’s all. Despite being dynamic and sealed they gave me no air pressure issues at all.
Aesthetics: Pretty understated. They are mostly a shiny gun metal colour with a very helpful red or blue band to denote which ear they belong in. they look like they could cost rather more than they do.
Sound: On paper these have plenty of flaws. They are too bassy, the bass is too humpy, the highs lack and yet have a bit of an edge. But I find I forgive them all. They have superbly fun timing and I just liked. I liked them a lot. They are so fun and bouncy. They are the antithesis of analytical which made them awkward to review but just step trying. Sit back just listen to the music and enjoy it. That’s what these want you to do and when you do you’ll stop noticing the technical failings. They capture an entertaining whole. The bass is so nicely timed. There is just so much that I find enjoyable that I completely ignore its technical mishaps. This is an IEM that doesn’t want you to listen to it but to the music and that it’s getting right. It’s just such an enjoyable and pleasing style of rendition. I really think it ought to please most if not all and in particular those who like a good chunk of bass. Its firm, powerful and punchily potent! Smiley face.
Value: Great, its currently hard to actually buy one but they sound fab, bundle is superb and the build quality is outstanding. I am really not sure what else you could want. Unless you just want a completely different sound signature of course, neutral and analytical these are not.
Pro’s: Fun in spades, build quality, accessory bundle.
Con’s: Deeply not analytical or neutral.
This is a quick review of the DUNU DN-22M Detonator.
I've never heard of DUNU until a few months ago. I was always curious about their IEM so when I got the DN-22M I was very excited.
The DN-22M comes with an abundant of accessories for the low price of $45-$50.
The DN-22M comes with plenty of tips and accessories. I like the little detail they put into this IEM.
7 pair of tips
The DN-22M is well built, it feels solid and look great thanks to the metal construction and gunmetal chrome finish.
The cord is about 4 feet and is on the thin side and microphonic is not the best. The 45 degree 3.5mm plug works well on phones and mp3 player with recessed headphone jack due to big aftermarket case. The microphone works well and my wife didn't have any problem hearing me. The cable management strap is a very nice touch
I've always had issue with earphone comfort and fit. It's hard for me to get a good fit and if they fit in my ear canal than it become uncomfortable after a few minutes. With the DN-22M I didn't have much difficulty getting them to to fit. Surprisingly the default tips was a perfect fit for me, I didn't have to insert them in deep like other earphones I've tried. I'm pretty sure the provided tips will work for most people. Isolation not the best, with the music off I can hear people around me.
I decided to use my Samsung Galaxy Nexus for this review since it was the picture of my gnex that got me this review sample.
I'm a basshead so bass is important to me. Using my normal bassy tracks from Master P and Zapp and Roger the DN-22M delivers good clean lows with good impact, it never feels lacking in anyway. The mids are very good, vocals sounds good and natural. The only negative is the highs. At low volume it is very enjoyable but when you turn it up it become ear piercing, especially when listening to dubstep. This can be fixed with EQ but for those who are sensitive to highs and don't have or want to EQ this could be a problem.
DUNU did a lot of things right with this earphone. The DN-22M is a very good, very well built, and very good sounding earphone for not a lot of money. It's come with a generous supply of tips and accessories. The DN-22M should be at the top of the list if you're in the market for a low price earphone.
I would like to thank Rocky for sending me the DN-22M. Due to an ear infection this review is long overdue. This is just a quick impression/review. I will add more to it at a later time
Pros - Great Value, Abundant Accessories, Quality Build, Working Android/iPhone Microphone
Cons - Weight for some wearers, Microphone placement for over ear use
DUNU Detonator DN-22M Review by TrollDragon www.dunu-topsound.com
In this review I will be looking at the Detonator DN-22M from DUNU.
If parts of this review are very similar to my review of the Tai Chi DN-19, that is because DUNU keeps a nice consistency with product packaging and accessories.
I would like to present to you their first model with a microphone specifically designed for smartphones the DUNU Detonator DN-22M.
The attention to detail that DUNU puts into their product presentation is impressive, just like the Flagship Tai Chi model these Detonator’s have the exact same packaging, consisting of an outer sleeve, with an inner box that has a side flap magnetic catch.
The Detonator DN-22M and the protective case just below them.
Upon removing the tray there are generous accessories to be found
The Detonator DN-22M Earphones
A rigid protective single zipper case
The familiar soft leather-like draw string pouch
A generous quantity of tips are included.
3 pairs of Sony Hybrid in S/M/L
3 pairs of Large Bore in S/M/L
1 pair each of Double Flange and Triple Flange set in M only.
(I would like to see DUNU provide some “Comply” style tips in the future, one pair of S/M/L would be a nice addition.)
Warranty / Maintenance Card
Cases: The soft leather-like draw string pouch has the company logo stamped into the material with a name tag sewn into the side seam. The drawstring is knotted and the ends are melted to prevent fraying.
The rigid protective case is nicely styled EVA case with the DUNU logo on top. It is only single zippered so you will have to zipper all the way around to open and close the case.
The zipper has a unique pull tab in the shape of the DUNU logo’s stylized “D”
The DUNU Detonator DN-22M:
Microphone: -45 +5dB
SPL: 112 +-2dB
Impedance: 16 Ohm
Frequency Response: 20Hz~20KHz
Noise Attenuation: 26dB
Cord Length: 1.2m
Plug Type: 3.5mm (45° Angle)
Like all other DUNU earphones the Detonator DN-22M are manufactured very well, the body is all metal hence the 27g weight. The finish is a nice gunmetalic chrome with logoed aluminum end caps. A red and green band around the body of each earphone denotes the R and L designations. Unlike the DN-19 these have no Braille marking for R & L that I could find.
A 90cm non detachable cord terminated with a 45° angled 3.5mm TRRS jack has a rubbery coating and very little memory. The standard DUNU cable management strap is included on the cable and is very handy. The Y Splitter has a puffy DUNU logo and a slider. The 35cm cable from the splitter to each earphone is one half the thickness of the main cable, the left cable has a microphone/single button module 15cm from the earphone. When you wear the DN-22M with the cable down, the microphone sits a bit below the jaw line and the cable itself is quite microphonic. If you wear the cable over ear, the microphone sits just below your ear at the end of the jaw and the cable noise is reduced quite a bit.
Driveability and The Microphone: I tested these earphones on my Colorfly C3 and HTC Desire HD, both these devices powered the DN-22M very well considering the Desire HD has a very poor level of audio output.
The microphone/single switch module worked very well with the HTC, it allowed you to answer/hangup phone calls and pause/play audio. The audio quality of the microphone and sensitivity surpassed that of the HTC’s internal microphone.
Just as a test I plugged the DN-22M into my FiiO E17 / E09K combo, with the volume control at 9 o’clock there was good volume for listening.
Earphone Fit: These earphones fit very well in my ears with the large Sony Hybrid tips, the earphones are round and straight so there are no issues with depth like I had on the DN-19’s.
Considering the weight of the DN-22M, they are really quite comfortable to wear for extended periods.
The Sound: Since I managed to get a proper fit easily on the DN-22M I had a chance to listen to quite a variety of music with them.
The first album I listened to was Chesky Records
“I-Ching “Of The Marsh And The Moon”
The second album I listened to was Juno Reactor
“From the Land of the Rising Sun Inside the Reactor II”
The third and final album was another Chesky Records
“David Hazeltine – Manhattan”
The sound of these earphones is quite good for the price point of $49.99
Bass: The Bass on these headphones has an abundant lower register so I found them quite enjoyable. The stand up bass in the tracks of the Manhattan album sounds good and well defined not over powering any of the other instruments. The Juno Reactor album has quite a bit of Bass on it and can be a little too much for some, the music is electronic and therefore quite different than the standard instruments of the Manhattan Jazz album. These earphones do not have the most bass I have heard, but they put out a satisfying amount.
Mids: The Mids are good, the piano on Manhattan is right there in front of you, very clean and well defined. It is very enjoyable to listen to. The “Restaurant” sounds from the I–Ching album are very well reproduced, the people there are talking and clinking tea cups right around you. The yanggin and erhu are faithfully reproduced from this incredible album. I you have not heard the album then please pick up a copy, it is an amazing journey for the ears. On the DN-22M it sounded as good as on full sized headphones, just with a much smaller soundstage.
Highs: I am not a fan of sharp or piercing highs, the highs on the DN22-M’s can get a little piercing with certain songs and instruments, cymbals can get a little loud and sharp on certain tracks. I had some Infected Mushroom queued up to listen to as well, unfortunately some of their tracks can get a little harsh and piercing with synthesized very high pitched voices under full distortion. These tracks were definitely not fun to listen to on the DN-22M without some equalization.
Final Thoughts: The DN-22M is another quality product from DUNU-TOPSOUND that is every bit worth the $49 asking price in my opinion. Be aware though that they are all metal and a little heavy, but for those of us with large deep ears they fit well and are very easy to get a good seal with. Excellent isolation and a good quality microphone, so if you have a smartphone and are looking for a quality pair of IEM’s, give the DUNU Detonator DN-22M a try and see if you don’t agree.
great value for the price point of $49
quality DUNU build
microphone works with most smartphones (HTC & iPhone)
weight might be too much for some
microphone in a bad place for over ear use
I would like to take this opportunity to thank Rocky and DUNU for the sample I received for review.
And I would like to thank anyone who actually read to the end of this review.
Also, I am not a photographer.
Constructive criticism is always welcome.
