Pros - Suits most of the geners, nice bang for bucks, spleldid mids. nice package.
Cons - life less highs.
Getting started:- (accessories and miscellaneous)
Up close and here we go again, for Brainwavz. Just a week ago I received Brainwavz M1, yeah these guys are really generous and it’s not a new model from any angle (a few years old), and the reason I received this review unit is because Brainwavz are promoting their lineup of M series. Most of us must have heard of this earphone as a good mid centric phone with good bass. And the provided accessories are generous too, it comes with the usual red and black carry case, cable clip, 6 pairs of single flange eartips in 3 different sizes, one pair of bi flange and comply s-400.
Cable is really nice, internally braided, microphonics is not a problem at all, and with the cable clip it stays in place. Build has nothing to complain about but the lack of any kind of strain reliever at the earphone end is a bit bothering, 90 degree plug means I am happy, as I tend to put my DAP in my jeans pocket and a straight plug can damage the 3.5mm socket when sit or bend, design is not bad too, plastic back with aluminum nozzle looks good, sadly lacks a cable slider. L/R marking is clearly visible, and this earphone is comfortable enough for longer hours of listening, which means we can move on to Sound section.
Main business area, Sound quality:-
Thanks to Brainwavz, I have the S0 with me to compare and when it comes to bass, it’s kind of under emphasized on the m1, not lacking but nowhere close to bass head level too, lacks some impact but extension is good and good texture too. It’s in the line with the mid, may be just below. Thanks to the controlled mid bass, bass is not boomy and don’t bleed into the mids, surprisingly these have enough sub bass and again thanks to the mid bass you can hear it but cant satify your sub bass needs. Overall bass is like a bit held back, not exactly immediate, but pace is good, it’s more precise this way. In the other hand, S0 is more boomy and impactful, moves more air and gives up some bass precision as it bleeds a bit in comparison. M1 got enough bass to keep you seated but you should not buy these for its bass for sure. But it will be difficult to fault its bass resolution. Involving and engaging.
Now we are at the main business end, mids, the main selling point of these phones, most of us have gone through many entry level (at least one) earphones which are good with bass, and sometimes they get a bit sparky too, but doing the mids right is more like a tough thing to do, most of the time it’s left in the valley or the back seat, veiled and kind of under emphasized. But it’s not the case here. These phones are tuned for smoother but précised mid presentation, a bit thin when compared to S0 but its more forward. Pleasing, rich, forward, smooth, soft and a bit thin can sum up these mids. It can feel a bit clumsy with a few tracks with higher pace but it’s a minor problem. A lighter leaner presentation means lesser amount of fatigue too. Vocals are a bit farther still really intimate. Separation and layering is not awesome because of its smaller sound stage and can’t be compared to the S0 which is more rounded and bigger in comparison, mids do sound thicker too. S0 is miles ahead with sound stage. But is not as detailed in the mids as the M1. It’s the mid that holds the SQ of this phone together. And let me tell you why.
Because of the highs!! Which lacks much substance, really sorry but I can’t hold myself and would like to ask Why? “why this kolaveri di”, I like a bit more spark with the highs, and to me It’s like you got a lighter but it lacks much friction, you got a knife but its blunt and will require more strength to cut. And believe me I am kind of holding back here. It’s not totally missing. It’s like it’s in the class room but is not paying any attention. Extension is not good enough. Instruments are like you can say relaxed, laidback and takes a hit with separation and layering. I would like to believe that these highs have shrunk the sound stage. And here up top, S0 knocks M1 out. Sibilance is out of question, and sometimes this laid back style suits some who don’t like much spark with their highs. Not me. But you can try EQing.
Brainwavz has already made an awesome reputation of making value for money products and M1 is no different, even if it’s an older model, it’s detailed and précised mid makes it an outstanding all rounder at this price and complimenting bass is a plus too, thoroughly enjoyable, awesome for vocals, cohesive intimate and engaging. Would I recommend these, yes I will, these are good and really nice for what you pay, but would have been awesome if highs were a bit more lively.
That’s it guys, enjoy.
Pros - Light, balanced sound, great bang for the buck
Cons - Not as refined as it could be
Brainwavz was seeking new coverage of their M1 in-ear monitor. I was seeking an IEM in a pinch before leaving for an 8-day trip. I didn’t like the Brainwavz S0 too much, my HiFiMan Re-Zero IEMs hurt my ears, I’m now a spoiled audio snob that won’t use generic OEM earbuds, and full-size cans just weren’t an option for traveling with camera gear. The timing was perfect; Audrey at Brainwavz hooked me up with a pair of M1s for my journeys, and off I went.
But before you think that I am just going to praise these because Brainwavz provided them, think again. I tell it how my ears hear it, and as some of you may know, I’m not generally a fan of earphones, earbuds, IEMs, whatever you want to call them. So let’s dive into what these affordable hi-fi IEMs are all about.
When I opened the shipping parcel, I was happy to find the M1 in high-grade packaging with excellent branding despite these being a roughly $40 earphone. As I’ve mentioned before, I’ve been handling a lot of products from other leading Asian manufacturers like Cayin, Dunu, Fidue, Hidizs and T-PEOS for my work with Canada’s CTC Audio, so it was good to see the Brainwavz packaging is on par, if not better than, its competitors. In your hands, you’d think you’re getting a product that retails for more than $40—everything is neatly and securely packed and placed in its inner holders with care.
Another thing I have come to expect with IEMs competing in this price range is a variety of accessories to customize use and fit. The M1 follows suit by providing a Brainwavz-branded hard zippered carry case and shirt clip, and a variety of ear tips that include one set of premium Comply S-400 foam tips, one set of black silicone bi-flange tips, and six, yes six, pairs of standard black silicone tips (S, M, L).
The hard case is the same one that comes with the S0 I previously reviewed and has two pockets that will secure all of these things in place while you’re on the go. As usual, finding the tip that is right for your ear is key, so please experiment. I ended up using the Comply foam tip with the M1, which, to my ears, offered the best comfort, noise isolation and sound quality.
You’ll hardly notice the M1 housings in your hand, not because they’re small, but because they’re so light. The M1 has an ultra-light composite housing and slim tangle-free 1.3m cable. The design itself is modern and attractive, while maintaining a minimalist appearance. Despite the light weight and general lack of what I would consider “robustness”, the M1 feels solid enough and has held up well to being thrown in my luggage, pushed and pulled out of my camera bags, wrapped around my Hidizs AP100 DAP, and probably rolled over more than a few times when I fell asleep with them in during my recent travels.
As for cable microphonics, they’re minimal—practically nonexistent. The difference between the S0 and M1, for instance, is night and day with the M1 putting the S0’s bulky flat cable to shame. My only complaints I have with the M1 cable is the lack of strain relief may prove detrimental over time and the length of the Y split. The length of the left and right wires seems quite long and there is no slider on the cable to narrow the split. The reason this bothered me is that it could be easy to snag the cables on coats and bag straps, but this is really a minor annoyance more than anything else. I suppose the shirt clip could be used to alleviate this, but that’s not my preferred solution.
Internally, the M1 sports a large 10.7mm dynamic driver wired to a silver-plated OFC cable that terminates into a 3.5mm gold-plated L-plug. The cable can be worn down or over the ear. Of note, there are no plug adapters included with the M1 as it’s intended for use with portable devices.
The important part. Brainwavz claims that the M1 presents a “balanced sound” and “will leave your ears (and wallet) smiling.” Well, I actually can’t disagree too much this time.
The M1 performed very well for me across several genres and surprisingly never left me wanting for too much more across the dynamic range. Granted, I would never sit down for truly critical listening with these. But as a portable solution, I was pleased with the M1’s spacious sound stage, ability to center the musicians between your ears and a relatively balanced response. Instruments and vocals sound respectably authentic with smooth, clean detail retrieval. The M1 is truly easy on the ears without ever sounding too dark or recessed. Brainwavz claims the M1 will sound good with any genre of music, and the M1 handled all of my electronic, indie, punk, rock, jazz and acoustic folk tastefully with nice dynamics, sonic clarity and just enough vibrancy to avoid coming off as being dry or sterile.
The M1’s 10.7mm dynamic drivers are rated at 32-ohm, with a frequency response range of 20Hz-20kHz and a sensitivity of 110dB at 1mW. These stats will tell you right off the bat that they are relatively easy to drive, but will likely lack real deep bass extension.
Before departing on my trip, I ran the M1s through several hours of tracks from The Sound Apprentice Picks Spotify playlist. A mix of songs from the likes of Sleeping at Last, Fink, Bonobo, Odesza, Sublime, Minus the Bear, John Butler Trio, Mammal Hands, Miles Davis, Glass Animals and many more played through my desktop PC and ALO Audio Pan Am tube DAC/amp. Once I left town, I mated the M1s to my new Hidizs AP100 High Fidelity Music Player (thanks CTC Audio) loaded with my lossless audio library.
When the music first hit my ears, I was immediately surprised by the balanced sound and nice resolution. I felt that I was actually hearing the integrity of the recordings and these different amps at work instead of an artificial sound from poor driver tuning. The M1 delivered a refined sound that didn’t call any attention to any specific frequency range. Some people will find this sound boring, but I personally prefer to hear recordings and gear as they were intended to be heard.
So, about that bass. It’s tighter, less boomy and more natural than the S0. It has smooth extension, but it does fall short of rumbling your eardrums. You can hear kick drums and deep synths, but you can’t feel them until pushing the volume into deafening levels. What’s nice, though, is that the bass never overpowers or smears the performance.
From bass to mids, the transition is simply smooth. I’d prefer a little more “meat” in this region, but tuned as they are the M1 handled instrument separation and soul quite well. I found vocals to sound quite natural, a little thin at times, but generally enjoyable.
As for the treble, I haven’t seen a frequency response chart, but my ears want me to say that the highs roll off relatively early. The highs that meet your ears, however, are clean and easy to listen too, but things I hear with my reference-grade headphones I simply don’t pick up with the M1. But, that’s to be expected. So while the highest detail retrieval may be underwhelming for the critical listener, the M1 still manages to not come off as being too dark or veiled. To those that are treble-sensitive, the M1 offers your ears some liberation.
For long listening sessions, I found the balanced and mellow sound of the M1 welcoming. I never experienced any ear fatigue whether I was listening for hours poolside, getting some late night listening in before bed, or soaring through the sky on the flight home (only complaint here is that the drone of jet engines decimates the bass). That said, much like I stated for the S0, for those looking for cutting highs with a vast soundstage, you’ll be left wanting for more. And for the real bass heads, I’d advise you to keep moving along. But for the head-fi guy or gal that wants an earphone that can do it all well enough and cheap enough, the M1 might be the right choice.
To my surprise, I can honestly say that I enjoyed my time with the Brainwavz M1. I tend to stay away from IEMs, and after my disappointment with the S0 I had my doubts about this more affordable option from Brainwavz, but the M1 has earned a place in my travel bag—at least for now. The looks, build and accessories are all winning features, but the weight, comfort and sound quality are what seals the deal.
I’ll close this review by simply saying that the Brainwavz M1 in-ear monitor is for the hi-fi enthusiast that wants a no-frills, enjoyable and easy listening experience while on the go (without breaking the bank). Without any EQ adjustments, the bass goes low enough, the mids can warm your soul, and the highs are supple and smooth with just the right amount of shimmer to keep your toes tapping and you saying, “Just one more song.”
Many thanks once again to Brainwavz and Audrey for reaching out to me and allowing me to take the M1 in-ear monitor on my journeys abroad.
Pros - Excellent bass without being boomy, small IEM body, and wonderful accessories
Cons - Becomes boomy amped and at high volumes, no strain reliefs on the cable, soundstage is a bit constricted
Brainwavz M1: Mid-fi Saving Grace
WHERE TO BUY / COST:
California Girls by The Beach Boys found on Sounds of Summer - The Very Best of The Beach Boys – Track used to test the entire spectrum from bass, mids, to treble.
Propeller Seeds by Imogen Heap ( Instrumental ) – Track used to test soundstage and overall presentation of soundstage
River Flows in You by Yiruma ( Piano ) – Track utilized to see if the headphone / IEM represents piano in a realistic manor
Vivaldi Guitar and Lute found in the The Spanish Guitar Music Colección – Track used to hear the metallic sound of strings, echo of environment, and sound signature of the lute and Spanish guitar.
I have been listening to Brainwavz products for many years and find the M1 and M2 wonderful entry-level IEM’s. The M1 in particular is especially outstanding both in sound quality and fit. It is aesthetically pleasing, easy to insert, and provides a fun sounding signature bound to suit the needs of many listeners.
The M1 and M2 fit similarly, but the M1 has a smaller body which makes it easier to insert and hides the bulk of the IEM inside the ear. Brainwavz continues their trend of supplying myriad tips including some Comply foam tips with the accessories. Unlike the M2 the M1 comes with a plastic cable clip to help remove any microphonics found in the cable. Each earpiece is clearly labeled with an L for left and R for right, but they do lack any signs of extra strain relief like the M2. The jack is terminated nicely and protrudes at an angle just over 90 degrees making it fit extremely well into a portable snugged into a protective case.
Unamped: I tested the M1 using an iPod touch 5[sup]th[/sup] Gen as I use it as my primary travel music companion. The M1 remains a wonderful IEM for on the go music musts. They are bassy and fun without being obnoxiously so. The typical upfront sound found in almost all of the Brainwavz products I have heard to date remains intact. The treble is nicely rolled off to not bear down on treble sensitive listeners. The M1 is just a super fun IEM to listen to and anything I tossed at it sounded great on an unamped portable.
Amped: Amped the M1 became noticeably bassier and better controlled. The signature can be easily dialed in and grooves nicely with funk, smooth jazz, and some moderately paced rock. Some tracks become too boomy with the M1 heard in Vivaldi’s Guitar and Lute track listed above. A quick turn down of the volume knob mellows the bass and the M1 instills another fantastic listen.
The M1 is a favorite of mine and perhaps my new low-cost mid-fi IEM. The sound is just awesome for such a small single dynamic driver. Bass lovers will not be disappointed, but the M1 is not boomy enough to scare away the more delicate listener. The accessories are complete and very well thought out making the travel case and tip choices considerate critical listeners who remain on the go. The cable is well made and although it lacks the sometimes excessive strain reliefs of the M2 it is still constructed of fine materials. The M1 is very small which makes it ideal for smaller to medium sized ears. Those who have larger ears may want to move up to the M2 due to possible fit issues, but larger Comply tips are available that should accommodate almost all listeners. Back to my listening and I hope you all enjoy this collaborative hobby that is hi-fi!
Pros - Balanced SQ, value
Cons - Aesthetics
Here we go again. It seems like every other review I've done lately has been on some product from this up-and-coming company that is making a name for itself. Luckily for us, this IEM from Brainwavz is just like many of its brethren: a force to be reckoned with.
Bass: Just plain good. I've heard several of the sub $100 category from Brainwavz, including the Delta, S0, and S1. So far the low-end on the M1 is my favorite. The sub-bass is there (something not usually found in IEMs running under $100) and surprisingly capable. Macklemore's "A Wake" has some nice thump, but here's the kicker: no bleed! Would I classify these as basshead cans? Heck no. But, they reach deep enough for these ears and retain some excellent texture to boot. League's electric bass in "Lingus" is very clean and rich, and the low-end of Ma's cello in the fourth cello suite is surprisingly life like. I tip my imaginary cap the gentleman overseas who tuned the low-end on this little guy.
Mids Usually with single dynamic IEM's, especially in the lower price brackets, bass is easy enough to manufacture, and let's face it, a little extra juice in the upper end typically pleases the masses. The midrange however, is the coin toss. Either its way behind the frequency extremes, or so far forward that you can forget about any appreciable low end texture or upper end smoothness. I'm here to tell you gentlemen, that this simply isn't the case here. The Mids are very in line with their surroundings. Ed Sheerans vocals and amplified acoustic guitar on "Thinking Out Loud" sound just great. Very organic and easy to listen to. I will add however, that in busier jazz fusion and thickly-layered vocal tracks, the mids can be a little congested. At no point though, have I been offended by what the M1 had to offer with regards to the midrange.
Treble Once again: very easy to listen to. Don't let their price tag fool you. The upper end is as natural and clear as I've heard in the sub $100 range. Clean and natural with decent extension. Only on treble-heavy tracks did I hear any sort of sibilance and even then it was minimal. There are probably some hills and valleys in its upper end graph, but at times I've been pleasantly reminded of the RE400s treble response. Now, is the M1 going to win any awards for super-extension or instrumental separation? No. But when I put it through the gauntlet that is my 'New Cans' playlist, it played quite nicely with everything from classical to rock to jazz to hip hop to vocal-centric tracks.
Soundstage/Separation If I have to identify a weakness of this IEM, it's probably this one. That's not to say it's lacking or poor, but compared to the capabilities of the frequency range, the soundstage falls lowest on the proverbial totem pole. Because the upper end isn't exactly hyper-detailed, there isn't a lot of air or separation up top, so soundstage depth or width is pretty lackluster. Accuracy is just fine, but these guys certainly won't be tricking anyone into thinking that they're in a concert hall anytime soon.
Qualms in the interest of being thorough with and IEM that I've taken a liking to, I had to include a blurb about some things that I have found myself wanting. Before you read on, know that none of the following has to do with sound - just aesthetic and accessory preferences. From an aesthetic standpoint, the black plastic and faux silver housing feels cheap. Let's face it, no one enjoys something that performs well, but doesn't have the looks to match. Unfortunately, that's the case here. I understand of this sort of thing helps keep costs low, but a man's allowed to have opinions! (And while we're on the topic, why no cable slider?!) Also, the tip selection is pretty minimal. Including some of the red-core or foam tips that are standard with the newer Brainwavz fare would certainly make me a happier camper.
Conclusion: I've heard a lot of IEMs in the sub $100 category. From the SE215 to the RE400 and everything lesser known from the likes of Soundmagic, JVC, and Brainwavz, this price bracket is being overrun by offerings diesigned to bring the discerning listener more bang for his buck. I'll tell you straight up that the M1 from Brainwavz will be one of the first I recommend to anyone looking for great sound for less than a hundred. They're pleasantly detailed, natural, and very easy to listen to. Overall, an excellent IEM that deserves a look from anyone looking for an all-rounder in this price range.

Pros - One of the most balanced iems for a very low price
Cons - poor isolation, no moulded strain reliefs in the housing cable exit
Thanks to madiaplayer.cl the best audiophile-oriented shop available in Chile I got a M1 sample to test drive it and provide my opinion so you can give them a try if you like my description. This is my second review so please forgive any mistake here.
The M1 box is made of softened cardboard wich contains a transparent window that allows you to see the housings very similar in that respect to every single Brainwavz box and it is similar to the Pro Alpha package however, it is a more compact, a better designed one and its also easier to open. On its front Brainwavz tells you that M1 has a balanced sound , has a comfortable fit and that they come with a silver plated OFC cable. In the back of the box youl find technical details, information regarding the contents and accesories. It is also stated that the set has 1 year of warranty if bought from an authorized reseller of course. Inside the box you'll find another cardborad box that wraps a moulded plastic container wich displays the headphones themselves and a clamshell semi-hard case wich contains all the tips plus the warranty card. In the top of the outer box you will find the phrase "IN EAR MONITORS".
The included accesories are: shirt clip, 1 set of Comply foam Series S tips, 6 silicon tips (S,M,L) . Most people can have good seal with the provided tips I personally used the mid silicon tips with acceptable fit
Starting by the housing I can tell you that they feel solid but not abs kind-of strong but most people will not be able to damage them unless the yank the cable. Anyway they feel consistent and solid enough. the bore is about 4 mm. wide and is protected by a metal grille. The front porion of the housing is also made of metal and the rest is plastic but they dont look cheap. There are visible side vents and a tinny vent in front of each driver just beside the bore. the insertion level is moderate due to the housng design that resembles the rubber protected Pro Alpha except for the lack of rubber that is replaced by a plastic fender. Unfortunately M1 is missing rubber or moulded strain reliefs in the cable exit so they have a very obvious weak point.
The channel indicators are properly printed and are visible enough but there is no bump or Braille code marking to distinguish the housings after sunset.
Cablewise the M1 is a very good iem for the cable has memory but not at an annoying level. cable is shiny and not tangle prone but it is a little bit rigid though and it is terminated in a 45 degree angled plug which is a great decision in my book. While the ergonomics are good enough I would add a slightly deeper insertion to improve linearity and isolation.
Isolation and microphonics
Due to the side vents isolation is fair but not better than average. You may find improvements using the included Complys. The cable trasfers very little noise
My audio sources for the test
A 2006 Mac mini running VLC with a FLAC 24/96 playlist an no EQ
Ipod Nano 5G/8gb loaded with 320K mp3's without EQ
An Ibasso LOD plugged to my trusty FIIO E6 for amplification testing
A Nokia C7 with 16Gb of music in mp3 320K and 256K resolutions inside a class 10 MicroSD. Ufortunatery the Symbian music player cannot disable EQ
Selected tracks from the following artists chosen for the test run, most of them 24/96 Flacs or Ape quality
Lali Puna (indie electronic pop), Massive Attack (triphop), Tool (progressive metal 24/96), Autechre (Exai (IDM 2013,32 bits 24/44) y Amber) , Pixies (Indie rock 24/96), Tricky (triphop), Cibo Matto (pop/hiphop), Crystal Castles (electrónica amd noise), Daft Punk ( House), Pulp (britpop), The Brooklyn Funk Band (Chesky,24/96),), The Roots (hip Hop), Guided By Voices (Rock/Lo-fi), Jaco Pastorius (Funk Jazz circa 1970) , Leftfield (EDM), Rihanna (pop), Digitalism (EDM), Rage Against The Machine (Rock,24/96), Muddy Waters (Blues), Pavement (rock ,alternative), Art Blakey (Jazz circa 1960) y Puscifer (Indigo Children (JLE Dub Mix), an excellent track to test sub bass and mid bass, triphop 16/48). Astor Piazolla y Kronos Quartet (Tango instrumental), Rebecca Pidgeon (Country, Chesky 24/96)* KMFDM (Metal and EBM) Supersilent (Free Jazz, experimental).
I liked the M1 Presentation. I find it cohesive in spite of the treble extension which is not better than the rest of the M series. Treble decay and extension is in fact very close to ideal but nowhere near B2 levels (I know it's not fair to mention B2 here). Anyway cymbal crashes sound much better in the M1 than the treble crippled Pro Alpha. There's a sense of warmth that makes Jazz recordings sound full but not dark. There is little to gripe about these. The clarity and detail resolution is impressive for the price as well as separation which may not be poinpoint accurate but leaves most of the competing sets on this price bracket to shame giving a good run for their money.
Distorted guitars are a problem for lo-fi and mid-fi iems, but the capable M1 driver can be very snappy and misses very few details in really intricate parts of fast paced music and there is more than a hint of sparkle that does not prevent the M1 to lean to the warm side of analitycal. A commendable feature that put's the M1 in the neutral side of things amongst its M brethren. In fact the M1 makes it possible to distinguish between a 128K MP3 track and a Flac 24/96 file in a transparent fashion.
The M1 has a relatively high impedance and its neccesary to raise the volume a little more tan half way on an unamped IPod to reach listening levels in a bus or the tube.Even at insane volumes the M1 will not distort so its better to be careful and avoid raising the volume too much.
Voices and mids in general are only slightly below linear levels (nitpicking here) in the M1 soundstage. It would be exaggerated to call M1 mids recessed
they have an open flavor and are a little warm so they can image very rounded male and female voices. Lyrics are easy to understand.
The bass on the M1 is controlled and has good extension reaching sub bass levels but keeping a rounded tone althought not completely full: There is a good speed recovery that makes the Pro Alpha sound boomy and much less precise in comparison. The M1 single dynamic driver moves less air and its bass is more refined than Pro Alpha's and is probaly leaner than Soundmagic E10's. but it's more informative than the latter.
The M1 have certain qualities that makes them really close to a truly great monitor and I would use it for tracks mixing but it lacks some (very little, nitpicking here) treble extension to be used in professional situations. The M1 soundstage is spheric and wider than
its depth but enjoyable all the same
In conclussion, if you are in a tight budget and cannot spend money in a Vsonic GR07 or a Single BA and prefer a mostly neutral sound signature you can't go wrong with the M1. These are versatile and very musical iems.
Pros - Rich sound, Good Bass, Above average Detailing
Cons - The design and 'high frequency sounds' need to be bettered.
I purchased my pair of Brainwavz M1 two weeks back. In fact it is the first headphone that i purchased for quite an expensive price. Hence i don't know how many of you would take my review as a credible one.
My first impression of the product is that, its the best quality sound that i've experienced till date. Coming to the technicalities (that i'm not at all an expert in), let me say that Brainwavz M1 gave me the best detailing so far. The lows are quite conspicuous, which implies that the bass is superb. The mids are good enough, and if there is anything that could be bettered, it is the highs.
Talking about build quality and design (things that i don't care about much); the product seems to be quite impressive. The comfort of wearing is quite good. And the material is something that you can trust.
Something that I'm sure about is that, Brainwavz M1 is more than the best you could ask for in the price range; and something that wouldn't disappoint you at all.
