- mixed feelingsReview by KL
With the stock wide bore tips, you do get the clean and detailed sound of the B2 with added bass, but I wasn't always able to get a good seal, I really needed a tip size that lies between medium and large. With a bad seal, I either got piercing highs or a lack or bass.
With narrow bore tips, it is less airy and more congested and it becomes more V shaped.
If you happen to own Comply T-400 tips, it noticeably boosts the bass quite a lot and warms up the mids, you could say that it makes it more fun sounding.
As you can see you can get different sound signatures depending on what tips you use, and your opinion on the M4 may vary on what you hear.
When I first got these, I actually liked them quite a lot, I guess due to the excitement I bought something new, but after some time there was just something I didn't like about them. In particular when listening to metal and rock, there was an edginess to the sound I didn't like, sometimes the mids would sound a little thin too. So I do have mixed feelings about the M4, I didn't take to it as much as other Brainwavz models. (Posted on 5/9/13)
- Amazing for the priceReview by Jeong
First, the sound:
Overall tonal balance tends very slightly towards the warm side, with smoothed but well extended highs and deep lows. There is a slight but noticeable mid-bass hump that extends into the lower mids, but it isn't unpleasant (to my ears, at least), and lends some warmth to the overall signature. Horizontal soundstage is average, with not very much depth, but instruments on well mastered tracks (I used the album "Promise", by the Eminence Symphony Orchestra) are resolved well, and decay sounds subjectively quick, helping with resolution.
Just one thing:
Many other reviews here call the mids slightly recessed, but I'm not hearing that. The chords are slightly thicker than on my Sony XBA-4, and the tonality in the upper registers is noticeably colder than on my Klipsch X-10, but personally, I like that. Your mileage may vary, but nobody I know who has tried these have anything bad to say about them.
Simply put, these are amazing value at MSRP, and if you ever see them on sale for less than $30 (on Amazon.com, or right here on MP4Nation), please do not hesitate since there is nothing better for your money.
I know the M4s are said to benefit from amping, but again, I don't really hear that, here. The M4s do respond quite noticeably to different sources, though - specifically, different output impedances give different sound signatures. A source with output impedance of lower than 2 Ohms gives a noticeably darker and wider signature than a source with 6 Ohms measured, and there is decent synergy with FiiO's E6 amp (<1 Ohm OI).
I have not encountered any issues with noise floor using Cowon J2, Samsung Galaxy S3 (International), FiiO E6, FiiO E10 or iPhone 4S as source. (Posted on 3/28/13)

- Strange headphonesReview by Ihar
- Great ProductReview by Kijana
It comes with a hard case that can hold her iPod Nano plus the headphones and all the foam tips that are included in the packaging.
She used them on our recent vacation during the flight and sound isolation was good. They were comfortable and the sound quality was more than adequate.
Neither of us are audiophiles so it is difficult to provide an accurate description of the sound quality...but it is great for us. (Posted on 1/14/13)

- Great upgrade for my Galaxy SReview by Max
Highly recommended, your ears will thank you :) (Posted on 10/3/12)
- Superb bang for buckReview by Sri Harsha
The package is awesome as usual and the addition of Comply's are good. The original pouch had no inner pockets so it was difficult to carry the tips, but pouches from the new batch that I ordered started to have inner pockets which is really handy to carry portable amp/ Tips or even a extra pair of IEM.
Sound quality is awesome, I like them more than the M2.
I like the instrument separation and the sound stage. A superb bang for buck IEM from Brainwavz. (Posted on 9/22/12)
- Wonderful packageReview by Milon
I was skeptical about brainwavz products at first since it was a brand that i havent heard that much about but since it had pretty good reviews for the M3, I decided to go ahead and buy the M4's. With FedEx shipping, it got here really quick.
When I first tried them on, I didnt feel that impressed, the bass wasn't boomy nor controlled, soundstage felt cramped, and sibilance was present, I thought they were just another pair of overpriced earphones which were just going to be another passing fad. I left them there and decided to give it some time to burn in. After a good 10 hours, I don't know what was it but the sibilance left, the bass reached lower and was far more developped and the soundstage widdened. The overall clarity increased by a whole bunch.
All I can say is that it surpassed my expectations and it quickly became my most used pair of earphones, even surpassing my SE215's.
Sound : 4.5/5
Build Quality + Isolation
Overall the build quality was decent, although I felt that the cable was very thing, it survived quite a bit of abuse. The isolation was great, using comply tips. However, in the end, they still broke due to the heavy abuse from my workout sessions. I would suggest getting the version without the microphone if you don't need it because it's apparently sturdier.
Would I buy this pair of headphones all over again? Yes. At the 69.50$ price? No. If you plan on using it mostly for commuting and on the go listen, it's pretty good, but anything more intense than that, I'd suggest a pair of earphones sturdier.
Overall: 4/5 (sound is worth the quality issues) (Posted on 9/10/12)
- Awesome iems at an unbeatable priceReview by Erik
+ amp not required
+ multiple tips included (different sizes and one foam)
+ soundstage is pretty good (with foam tips)
- That i didnt have these sooner!
I cant think of anything negative to say about these iems, for the price you simply cannot go wrong, plus they come with a sweet little carry case too, what more could you want! (Posted on 8/16/12)
- Great Sounding IEM'sReview by Nerdsinc
Good product. (Posted on 8/7/12)
- Nice upgrade from M2Review by Randy
When I received it, I was so excited to try it on. Upon trying, sigh. There is driver flex on the right earpiece but I have already expected it due to reading reviews. Wire seems a bit thin.
So, the first eartips I used was the Comply. It gave ultimate comfort and the sound signature I got was a slightly U shape sound. I enjoy the balance of treble and bass.
So after a month or so, I felt that maybe I should try other tips and see how it goes. I went to try the normal (S) tips and yeah! I really feel the energy from the earphone. Very nice beats, soundstage and decent treble (though a bit harsh though).
Compared to my previous M2, which has a darker sound signature and less treble, I feel the balance in M4 with decent balance from each part (low, mid, high).
Nevertheless, I got it at a cheap deal but if I were to purchase at normal price, I would gladly purchase it. (Posted on 7/10/12)
- Great valueReview by Cibibikeru
First, I would like to say these are very good built. The aluminium housing is really nice with some fine details. Cable looks very nice too, better than the mic'ed version, loooks durable.
Came with many silicone tips (all sizes) and what I like most the foamies, these are different that those of my M1's, way better. There is also a carrying case that fits my Sansa Clip+ too.
Let's talk about the sound, I coupled them with both my Sansa Clip+ and my Iphone4.
Bass is good, clearly better than my M1, goes deep, a little too much upper bass for my taste, but not boomy, sounds full.
Mids are not recessed, they actually sound a little forward, I found them a little 'shouting" at higher volume, just at the point where the mids end and the highs begin, a thing I didn't encounter with the M1.
Highs is where things could be better, I like hearing detailed highs and while the M4 sounds good overall, I feel like there's something missing. High frequency is present and good but I get the feeling it cuts off at an early frequency, the extension is not that good, but overall it sounds crisp and precise.
Have in mind that this is a personal opinion, i find the M4 a little agressive, while they sound very good, it is not for me, I'll stick with the M1.
Thanks to mp4nation for providing very good sounding iems at very good prices, keep up the good work!

- Wonderfully ImmersiveReview by Faheem
The M4 is truly an exceptionally good sounding iem,They have a very fun sound signature with lots of controlled bass which never overpowers the mids,mids are good,treble sparkly but not harsh,overall I'm extremely happy with the M4s. (Posted on 6/29/12)
- Excellent for metal heads or rock fans. Review by Yunho
Be warned though, you'll need a good seal/fit or else these will sound tinny/bad. If the included tips don't cut it for you the included comply tips should.

- Brainwz M4 are perfect.Review by Pawel
The kit included three pairs of silicone tips, one pair of M-ek Comply, nicely made, tough and handy carrying case and clip.
The sound right out of the box is incredible. The scene is quite extensive, treble and medium looks pretty normal, nothing comes to the fore. I think it plus.Bass not go down very low but is it enough.
Headphones very comfortable in the ears, the cable does not tangle too much, it is very solidly constructed.
+ solid construction
+ sound quality
+ good cable that doesn't tangle.
- Bass could descend
If you are looking for some quality headphones, Brainwz are perfect. (Posted on 6/18/12)
- Made for portable listeningReview by kingpage
In summary, I like the M4 much more than I liked its darker little brother M2. M4 isolates as much as my HM5. Despite the change in presentation, I don't feel like I missed out a lot when I went from HM5 to M4. M4 sounds more stereo than HM5s and doesn't have a "deep" V shape (as some has said); instead, emphasis in the bass region is slight, generally clear, with a good sense of air and good detail. But initially I did find the lows were little congested, it seems to have improved after some burn-in. While it may not be bassy enough for true bassheads or balanced enough for those who love accuracy, I can see myself using M4 as a portable 'phone. M4 may be perfect for you when you're on the go and you would like to be able to hear a bit more bass than neutral in noisy environments.
I used to have driver flex issue with the right side when using silicone tips, but as soon as I switched to Comply tips the issue went away. The comply tips are super comfy. BTW, there are 6 pairs of silicone tips instead of the stated 3. (Posted on 6/18/12)
- Great pair of IEMs for the priceReview by Francisco
The included case was really great, fit my Clip+ like a glove. They come with lots of tips, none of them fit me really well. The cable is one of the best I've seen on an IEM. They are vented so they won't isolate that well.
I lost my pair of M4s and my music player and I'll probably buy a new one. (Posted on 6/17/12)
- Excellent Value...Another Brainwavz masterpiece!Review by Dr. Aveek Mukherjee
For that much amount,according to me,its bang for the buck!
The package was customary Brainwavz,with lush red colour,with a cut out to see the beauties(and revel). Needless to say,the package came unmolested.
Came as mentioned...The IEMs,artistically put up on a foam holdout,a nice hard carry pack...along with 3 pairs of ear tips,S/M/L...I put the Medium tips for myself..And theres the shirt clip to take care of microphonics...Also there is a pair of the famed Comply S series foam tips...a nice value add...and extends comfort during those long train trips...:)
All these came neatly packed in zip plastic case.
The IEMs are built well,those who shun "Made in China" pieces,should rest assured,that its built to last.
The wires look classy,and for a change,are actually averse to messying up...Phew.
The IEM casing is metallic...with a bass port...and the joints look well machined and durable...
The jack is an L type...angled at 90 degrees...some may love it...some might not...I love it...pairs great with my Fiio E6 amp :)
Only gripe is the Y junction...doesnt come up to par with the rest of the build.
Ohh...there is the 1year warranty...so guess we are covered!
Disclaimer: Perception of sound is a personal opinion,please keep it in mind before going up in arms against my observations.
Bass: As is the case with dynamic iems,the M4 excels at low frequencies...I've compared both the M2 n M4,and there seems to be a touch less bass in the M4,but its more punchy,and less aggressive than the M2...Suits me fine though. I especially like the low freq rumble...
Midrange: The mids are musical,not too laid back,not too in your face either. The vocals come nice and smooth...with detailing and texturing....it might not be as fast as the Armature driven iems though..but it only costs $50!! Its pleasant to listen to.
Highs: It does quite well for a dynamic iem...at least,imo better than the M2. The details are there...I did not find any sibilance...The highs are not too bright...but presented in a nice laid back fashion...its not dark either...You can hear the high notes,but yes,its not as fast as an armature.Overall,it shares ranks with the better dynamic iems.
Microphonics: Microphonics are always the bane of IEMs in particular...the M4 is,however remarkable in that aspect...If worn over the ear(looks kinda odd though),microphonics are really brought down.Also,using the supplied shirt clip,eases things up.
Overall acoustic rating: 4.5/5!
For $54.5...this is excellent value...considering the features and acoustic performance.
Overall,a nice addition to any collection. Another Brainwavz masterpiece. (Posted on 5/28/12)
