    Beauty over beat.

    Pros - Lokks beautiful, nicely accessorized, has a good and in offensive consumer related signature.
    Cons - AAh, lacks extension at both end, transparency and clarity could have been better.

      Brainwavz has become one of the house hold names in our audiophile, even when they don't make products competing with heavyweights, they make products that are more bang for bucks than most brands in this business, they make verity of products too, amps, headphones, BT earphones/ headphones, and their package is the best in my opinion. Who else ships an $25 earphone with a pair of comply, hard carry case and 6 pairs of silicone tips( Talking about XF-200 here)!!
     This time around I have a headphone from Brainwavz. They have couple of full sized headphones, HM5, HM7 to be precise, what I have here is the newer HM2, this one too sports detachable cables. It’s the cheapest of them all, priced $50, will compete with Headphones from Philips, superlux , JVC, and sony ZX & XB series headphones.
     I don’t own plenty of headphones, but I do have SHo9560 and JBL J55 to compare with HM2.
     P.S.:- I would like to thank Pandora and Brainwavz for this review unit. I am really sorry for this delay.

      Even when its priced $50, it comes with a hard carry case, helps while traveling.  There are two cables too, 1. with a universal remote and MIC with a volume controlling slider. It doesn’t control  volume from the device though, it just works on the preset volume, to increase volume, you will have to reach out for the source never the less. It does enable the user with some control.  the cable itself Is nice, isn't much microphonic and is really supple. 2. 2nd cable is a flat one without anything on it, just a simple line in cable. It's too is really low on microphonic and is really too.
     Ergonomically its one of the best $50 headphone you will find on the market shelves. Let it be ZX600 or even M20x, none of these $50 headphone is as comfortable as HM2. Its ear cups easily adjust to one's head shape and sits nicely over/on-ear. Over ear if your ears are small. It slightly goes on my ears but it’s the soft ear pad that makes the experience comfortable.
     There is no cushioning on the headband though, not uncomfortable. It doesn’t press on ears, which is a good thing for most.
    Those who want an compact foldable headphone, HM2's does collapse into the band hence takes lesser space when you want to toss it into your bag. Don’t forget to put in inside the carry case, for protection.
     As far as the look is concerned, it has dolphin skin finish on it, silver rings on ear cups looks nice. My friend even said it looks classy and futuristic at the same time, I do concur with him. HM2 is one of the best looking headphones for sure.

    IMG_20151201_175047_HDR.jpg   IMG_20151201_175126.jpg

     Now this one does have ship with remote loaded cable but it's more like a one button MIC unit and works just like other universal one button MIC units. That single button will pick calls and end, play and pause music, double tap will skip forward and triple tap will move back, you can control the volume from volume slider built into the remote but it won't help controlling source volume. MIC quality is better than average, sounds clear and slightly hollowed. Not bad.

     The official statement states that HM2 boasts a smooth sound designed to give a comfortable and enjoyable audio experience and I do agree with it. It's not one of those sparky, top end extended headphones but the one with a smoother and easy on ears signature. Its not V shaped, it’s more like a slide to be precise. Elevated bass, acceptable mids and turned down highs.
     Some songs I used:-
    Adele - set fire to the rain.
    Paul lindford and Chris vrenna – most wanted mash up.
    George Barnett- super hero in a ball and Down on me (this guy knows what he is doing).
    Hozier  - Foreigner's god. (beautiful song)
    Plan B - playing with fire.
    Chase and Status - No problem.
    Rise against - survivors guilt.
    Lupe Fiasco- Adoration of the magi Feat. Crystal Torres.
    Dotan - fall.
    Jessie J - sweet talker.
    Morning parade - carousel
    Bullet for my valentine - Truth hurts
     I would like to confirm that HM2 is burned for more than 80+ hrs and I have use the non-MIC cable. HM2 is loud enough, doesn’t require an amp and can be powered by most of these modern day smart phones.
     Now its not the type of bass one will find on srh440 or ZX-700 but from something like SHO 9560. HM2's bass has mid bass elevation in the 60-90HZ region and is fluffy, boomier and slow, decay is not good no doubt. This bass doesn't go as deep as something like sho9560 or even ath-j55 and even with its mid bass elevation it's not bothering.  Better than XB-400 for sure, XB-400's bass is seriously uncontrolled and boomier too.
     Even with its short comings this bass is not exactly bad, has good amount of details and some control, is fuller too. Impact is good , moves good amount of air with a slightly softer slam.  sadly its not exactly good with high speed tracks and slightly lags with house and electro music.
    One should not expect much control and precision from a $50 headphone especially in the department of bass, but this bass is enjoyable for average listeners, especially those who like some bass but not whole lot of it. HM2's bass more cushy than forcing hence making it a good companion for longer listening session.
     For me mid range is the life of a song and HM2 doesn’t really excell here, it just lacks emphasis, kind of in a valley. Vocals are good. Both male and female are equally energetic and sharp, notes are deep and have desired thickness and has enough presence to keep me seated. Details and precision is good, instruments are detailed. When it comes to instrument clarity and precision, HM2 is manageable, it sounds cohesive with nice texture.
     My biggest concern resides in HM2's inability to exhibit transparency, hence clarity suffers. Micro detailing is mediocre at best. Equalizing does help but it still not as clear as I was expecting, it feels like there is a barrier somewhere in between. Everything sounds slightly veiled and unclear.
     This mid range is not even on the same page with bass, it feels small in front of bass. It's like Bass is flowing from a bigger pipe.
     I am not totally but slightly disappointed. It could have been clearer, and should have conveyed better  transparency.
    Sound stage on the other hand  Is better, width and height is good. depth is okay. Havent heard a $50 closed back headphone with bigger stage.  Samosn SR850 is a different thing.
     I do want to skip this. I really do, nothing to write about. Lacks extension, lacks energy and spark, are not transparent from any angle. Cymbals sound muted and unnatural, same for other instruments too. Separation layering and placement are really good but it just simply lacks good amount of presence.
     This type of sound signature does helps with longer sessions and makes it comfortable for long listening sessions but for $50, HM2 could have been clearer and should have had better top end presence.
     Umm, it is what it is.

    Short comparisons:-
    VS Philips sho9560:- This headphone is made for heavy duty usage, and its tag of tested on animals reflects it properly. Still its SQ is  not bad. 9560 has deeper bass, with slightly smaller but stronger impact, while moving smaller amount of air, HM2 moves more air, has bigger bass but impact is softer. Overall its bass is smaller in quantity. Thankfully 9560 has clearer and more transparent mid range, but lacks details. Separation is okay but layering is a mess, forget about instrument placement, stage is really narrow too. thankfully highs have some more energy and extension. Overall 9560 has better balance but less details. HM2 is a better headphone for sure.
     Has better transportability and comfort too.
    VS JBL J55:- J55's bass is the best of the lot. Has better decay and is not cushy. Has nice impact and moves good amount of air. Has better depth and doesn’t have much of a mid bass hump. Has better details and clarity is better too. J55 has good mids transparency and arguably the better one of these 3. At least it doesn't feel like holding much back even when it's just a little bit clearer. Transparency, separation, placement, everything Is good. Has the most amount of top end extension and energy too. Stage is good for an on ear headphone. Well rounded and has good sense of space too but HM2 has taller and wider projection. HM2 does beats it when it comes to overall details, performance and sonicality.
    VS Samson SR-850:- Winner, flat out winner in every segment, faster bass, better details, better control. Mids are really clear even when in the V. Top end extension is really good, has better energy too. Transparency, separation, instrument placement, everything is better. Stage is not bigger sadly for an half open headphone it’s a shame.
     Beats HM2 easily unless you don’t like highs and want bigger bass.

    IMG_20160408_193106.jpg   P60408-172614.jpg
    Samson SR850, all dirty and messed up. Sho9560 on right.

     Now HM2 is not an headphone for details hogs for sure. Its targeted towards the youth who are not critical about details and prefer musicality over serious listening. From my review one might access that its mid range is really bad but its isn't, it just feels a bit held back and highs are tuned down.
     An average consumer or someone who doesn’t enjoy much top end energy or spark will love this headphone. Nicely packed and accessorized, beautiful looking headphone, sounds better than most on the market and sound signature is really enjoyable but could have sounded better.
     If you are looking for an inoffensive, bassy, blunt and soft sounding, comfortable headphone for long listening sessions, without making a huge hole in your pocket, go for HM2. It's one of the better $50 headphone for sure.
     This is it, Hvae a nice day guys. Cheers.

    Brainwavz HM2 Quick Review by mark2410

    Pros - I love its looks. Solid construction. Thick and weighty, rich sound.
    Cons - Very flavoured sound. So so detail retrieval.
    Brainwavz HM2 Quick Review
    Thanks to Brainwavz for the sample.
    Full review here http://www.head-fi.org/t/796113/brainwavz-hm2-review-by-mark2410
    Brief:  Big bass, great looks, tiny price.
    Price : US$50 or abouts £34
    Specifications:  Drivers: Dynamic, 40 mm, Rated Impedance: 32 Ohm, Frequency Range: 10 Hz ~ 20 kHz, Sensitivity: 104 dB at 1 mW, Maximum Input Power: 100 mW, Plug: 3.5 mm, Gold Plated, Detachable Cables: 1.2 m Flat Cable & 1.2 m Cable with In-Line Microphone
    Accessories:  Headphone Hardcase, 1.2 m Flat Cable, 1.2 m Cable with In-Line Microphone,    Instruction Manual & Warranty Card (24 month warranty)
    Build Quality:  It may be all plastic and cheap but it’s nicely put together.  It’s all pretty seamless and the plastic feels nice in the hand.  It has a soft touch coating and the joints are reinforced with metal.  Time is the only true way to say how well things survive but I would expect it to live a long life.  It is much nicer than you would expect of such a cheap product.
    Isolation:  It is so so.  Sure it’s an on ear so it’ll depend wildly on how well it matches your ears but I found it passable.  It’s fine for typical out and about, on a bus stuff.  However I’d be hesitant to go wild with the volume dial on a bus and it wouldn’t be my first choice for a flight or on the Tube.  It would be better than nothing but it’s around the level of slightly open dynamic IEM’s so it’s not an isolation master.  Better than nothing and probably fine for most people wanting something on ears.
    Comfort/Fit:  Well for me it was good.  It got a little tiring after several hours, like around 4 or 5 hours but mostly it was fine.  It’ll be dependent on your ears but for me it was fine, a great balance of clamping tight enough to feel secure but not to be ear squishing.
    Aesthetics:  I am huge on the monochromatic thing and these slot right into that.  Mostly matte black construction with a matte grey offset, grey ear pads.  I’m not sure I’m wild about the little hint of flare in the polished metal band highlighting but as overall visuals go, I am a big fan.  One of if not the best looking, or best suited visually to me, headphones I’ve stumbled across.
    Sound:  If you have read my HM9 review, that. 
    “Thick, warm, smooth, gooey, squishy loveliness.  The bass is grand and warm.  The mids are thick and smooth.  The highs are soft and gently glistening.  If you want neutral, all of detail, dry crystal clarity then you will be epically disappointed in these.  They are all about creating a cosy and enveloping aural environment.  The bass is expansive and weighty, I can see very many likening it a lot.  It’s not particularly agile or skilled but it’s not in the least trying to be, it’s about having a good time.  Poppy bouncy stuff goes grandly together with it.  Mids, well they are a bit over thick low down and faint subtleties are lost but again, its calling is poppy bouncy stuff where vocals are only ever so so at best anyway.  The highs continue the theme, genteel and gently glistening away which does obfuscate the fine detail.  So what?  Most pop is shoddily mastered and dynamically compressed within an inch of its life so you’re hardly losing a lot there.  The HM9 is all about the warmth and entertainment, at that it succeeds.  Big warm bass and is incredibly non fatiguing while doing it.”
    The only difference is the 2 is at a vastly cheaper price point and thus is accordingly not quite as skilled as it big brother.
    Value:  Excellent, as is pretty much a given from Brainwavz.
    Pro’s:  I love its looks.  Solid construction.  Thick and weighty, rich sound.
    Con’s:  Very flavoured sound.  So so detail retrieval.

    Nice sounding "street" headphone for those who don't like to use IEM's or want the style of a full headphone.
    Written by shockdoc
    Published Jan 24, 2016
    Pros - Style (subjective), decent sound, flexible design including removable cable.
    Cons - Clamps a little too tightly for my head
    I was quite curious to hear this headphone since other than a blu tooth 'phone designed for kids I hadn't really had the opportunity to listen to a full size Brainwavz offering. Unpacking the box I was pleased to find a removable single sided cable (and an extra, with mic/controls) as well as Brainwavz' very nice memory foam earpads. A nice, sturdy zippered case was also included. I'm not a super style conscious person but I see a lot of Beats and other popular street headphones worn by the younger people at my gym and, to my eye at least, think that the HM2 stands up well in looks and function to what I see the younger crowd wearing. I was a little surprised when I put them on my head that they covered my (average sized?) ears completely and were not, at least for me, 'on ear' headphones. That's a big plus in my book as the main reason I use headphones and IEM's is to block out external noise, hopefully without cranking the volume to a level that could eventually damage my hearing. It may be, however, that someone with larger ears won't quite clear the edges of the foam pads and they might indeed end up as 'on ear' types. 
    The headband has no padding, a bit of a disappointment for me, but I suspect it's mostly a style choice by Brainwavz. It didn't seem to affect comfort that much to me. They also seemed to clamp a little too tightly on my average to large sized head but I assume they'll loosen up with time. I did a small amount of listening to a number of tracks before placing them on my burn in rig (yes I believe in burn in, especially for dynamic drivers). Initially I was pleasantly surprised by their rather rich, full sound. Of course being closed they didn't have as much space and soundstage as I like but it wasn't bad at all and exceeded somewhat my reference on ear JVC HA S400 slightly. I used those to compare as they are in the same general price range and are closed as well. The biggest problem with my old JVC's was that they were on ear and were EXTREMELY uncomfortable to me even after just a few minutes. I actually modded them with Brainwavz accessory memory foam pads (placed over the OEM pads) to make them over ear and more comfortable. This mod made the JVC's the equal, or slightly better than the HM2's for soundstage. If you don't have a could of sets of Brainwavz memory foam pads to play with, I recommend you get some. They work with a number of headphones and are quite a bargain IMHO.
    I listened to the HM2 briefly after about 50 hours and stopped burn in after 100 hours not noticing anywhere near as much sonic change as I usually do with the brand's IEMs. Overall the sound is pleasing with no particular part of the sound standing out too much. In a word I'd call the sound mellow. There is plenty of bass, the midrange is nice, not too forward like the JVC's can be at times and the top end is there if not a bit subdued for my taste. I wouldn't really call the sound signature bland, but I wouldn't necessarily call it exciting either. I did notice, after listening to a number of different genres, that unlike some 'phones in my collection, they held up pretty well to just about any type and style of music. I usually term this characteristic as "forgiving" as it can be somewhat disconcerting with certain headphones when you run across the odd track that for some reason just sounds terrible, or at least "off". Haven't found a track yet, with these, that doesn't sound at least okay. 
    Finally I did extensive A/B comparisons with the JVC's on many many tracks, leaning heavily on acoustic and orchestral music, since to me this is the true measure of a headphone, how it recreates the natural harmonics and nuances of acoustic instruments and the human voice. I have to admit, that after at least a hundred hours of listening I prefer the overall sound signature of the old JVC's for detail and resolution. But the HM2 surpasses them in bass and more than anything in design, build and COMFORT. I kind of wish I could stick those old carbon nanotube drivers in the HM2 and this 'phone could easily become a daily driver for me at the gym and commuting on a bus or train. Of course with any kind of constant external noise like in the aforementioned, any big differences in detail and resolution become mostly moot and the added bass gives the music more balance and weight. For short bouts of critical listening I'd still grab the JVC's but after 30 minutes my head and ears would be screaming for the HM2's. What I'd really like to know is how these hold up to the ubiquitous Beats that many kids wear. From my best memory the older Beats I've listened to were not even in the same ballpark. They were bloated and boomy and more than anything simply not anywhere near close these especially for the asking price. Hopefully they've gotten better but I'm skeptical and almost certain that when you consider the huge price discrepancy the HM2's would blow the Beats out of the water. The HM2 is, I think, a definite consideration for a daily driver "street" style headphone.
    Finally I took them for a mini "torture" test to the gym. While they didn't block noise like my better IEM's they did a decent job and if, like many younger people, I preferred this style I wouldn't hesitate to wear them for workouts. The single sided cord stays out of the way nicely and, aside from some heat buildup, they were comfy for the entire 2 hours of my weightlifting and aerobics workout. My next step will be to see if I can persuade a few of the guys at my gym to listen to the HM2's and, in turn, let me listen to their Beats and Sonys to see what differences I can discern. Look for updates later on to this review. My overall review 'ratings' are based on my determination of sound, build and quality as a function of MSRP compared to other similar headphones. I welcome any and all feedback.
    Thanks to Pandora for allowing me to review the HM2's.

    Pros - Sturdy build, comfortable pads, easy sound signature
    Cons - Minimum size on headband too large for some, cheap
    Brainwavz have just released a new headphone, the HM2. I was offered the opportunity to review a pair, and accepted. In case you couldn’t tell from my ramblings below, I have received no financial compensation for my thoughts, they are entirely my own.
    I am neither old, nor young, and am on the cusp of being or not being a millennial. I have been a lifelong music-listener, with interests that range far and wide, from African Jazz all the way through to EDM, with plenty of stops in between (Tuvan Throat Singing anyone?).
    I use a variety of sources. My employer saw fit to equip me with a MacBook Air that sometimes acts as a source for me. I also use a Pono player, iPod Touch (1st gen), Sansa Clip+ and my iPhone 5. At the time I did this review I was also testing the Shanling M2. All of my files are FLAC at 16/44, with a few small exceptions in FLAC again but at higher resolutions, or in MP3 at CBR 320.
    The headphones arrived in a nice box, designed and branded for the HM2, nothing generic, but nothing special about it. Inside, in a clear plastic bag, was the hardcase that comes with the headphones. In the hardcase was the headphones, and two cables, one a simple, flat ribbon affair, the other a round one with an analogue volume slider and control button (for taking calls I assume). The case has enough room in it to hold a DAP and/or an amp if they are modestly sized. Nothing mind-bendingly different here, just perfectly adequate. I have not included pictures as Brooko has done a wonderful job of that on his review, and the Brainwavz site has plenty of eye-candy.
    I was a little dubious about the ribbon cable. It seemed awfully fragile. I plugged it in though, and it works well. I was a naughty fellow and gave it a few yanks to see if it would snap. Nothing happened though, its rather solid, despite the way it looks and feels. I questioned the logic behind a flat cable for listening until I realized how light, unobtrusive and un-microphonic it was. Nice move Brainwavz design team.
    The round cable with the slider and button was nice. I expected the slider to be noisy and difficult to use accurately, but its not. Perhaps with age it might become a little cantankerous, but then again, won’t we all?
    The headphones themselves are rather nice looking. Smooth, no sudden angles, and sleek, made from a nice, solid, matte plastic. They have no headband pad, but are so light they don’t need one. The adjusting sliders are solid feeling, and the folding hinges don’t feel like I’ll be snapping them with my clumsy hands any time soon.
    Clamping force is in the Goldilocks zone….neither too hard nor too soft, and Brainwavz, being Brainwavz, have equipped these headphones with very comfortable pads. I usually battle a little with supra-aural headphones, these are nicely designed to simply slip on with almost no fidgeting and fiddling required to get a good seat (even on my slightly larger than necessary ears). I was able to wear them for extended periods without significant discomfort.
    Soundwise, Brainwavz is pretty open about the signature. It’s smooth and easy going. This means a noticeable tilt towards warm and bassy. The HM2 do really well with EDM. When I listen to EDM, I tend to listen to odd-ball stuff like the Orb, Flying Lotus, Future Sound of London, Four Tet, Boards of Canada and Caribou. The bass doesn’t reach as low as some considerably more expensive headphones, but it has a very comforting presentation, one that bleeds just a tiny bit into the midrange. This was only noticeable on a track that called Flag, off the album Nana by Xavier Rudd and the United Nations. It starts off with vocals only, and then has a rather deep and heavy beat drop in.
    I also listen to a lot of Jazz, and some Blues and Folk. Again, that mellow sound signature means these all sound very nice. I don’t hear as much detail as I do on my vintage pink driver SR60 Grados, Sennheiser HD600, or my Yamaha YH-1, but again, these are not made for the same purpose as those, and do not sit in the same price range.
    Isolation is so-so. They are closed, but aren’t an anechoic chamber.
    Overall the HM2 is a great headphone to buy simply to fling into your backpack for work, or give to your kids to abuse on a daily basis. They are sturdy, easy on the eyes, and made to be worn for extended periods with their excellent pads and easy-going sound. If you’re looking for a nice portable that won’t break the bank (or your heart if you lose it), the HM2 fit the bill nicely.
    1. nmatheis
      Love your reviews. They always make me chuckle. Nice blend of no-nonsense review with an easy-going writing style. And... you listen to A LOT of the same electronic music as I do, dude! BoC, Caribou, Four Tet, FSOL = Awesomesauce! If you really wanna go off the wall, try some Raster Noton stuff like Alva Noto + Ryuichi Sakamoto, Kangding Ray, and Mika Vaino. Mindblowigly awesome IMHO!!!

      Thanks :). I always feel like we have a lot of serious reviewers. There's room for a little of a more informal voice.
      Thanks for the suggestions...will have a look at them. Am listening to Mbongwana Star's "From Kinshasa" album right now. Great stuff...think Thundercat from Brainfeeder raised in the Congo...

    I have been working with Brainwavz for a while now reviewing a ton of their IEMs and a few of their headphones. I must say this is the first headphone they have produced that caught my eye right out of the box. The HM2 is a wonderfully compact, sleek-looking, simply designed headphone. Brainwavz claims to have captured a “smooth sound with punchy bass” as well as producing a very comfortable headphone. Let’s take a look if they meet these goals.
    I really appreciate how Brainwavz is not shy of improvement and innovation. So many companies design a headphone and call it good. Brainwavz appears to be listening to their customers and trying to make gear designed for its listeners. The HM2 is no exception in that it is a very clean-looking headphone that keeps comfort at the forefront. The earcups go completely around my ears making the HM2 more comfortable than my more expensive go to portable, the noontec ZORO II HD. The headband easily adjusts and the left/right indicators are easily visible. Thanks! The earcups swivel and contour nicely to the shape the head. The cables are detachable making them easily replaced. My one immediate gripe is the lack of a headband pad. The curve is great, but because our heads vary in shape and size, the lack of pad causes some discomfort. Hopefully we will see a version with a pad that spans the width and length of the headband…at least down to the hinges.
    The exterior of the headphone looks and feels well made with no obvious signs of cost cutting. The earcups can be replaced and simply pull off. I will note that these are closed headphones and tend to seal around the ears such that they can become very warm. The heat from your head will not easily escape the seal. It is not like they are sweat magnets, but they tend to keep my ears very warm.
    Provided are two cables. One is flat terminated at both ends with the TRRS 3.5 mm jack plugs. The other is a round cable that holds the remote. The remote is simple. It only has a slider for volume control and a single stop/play button. The flac cable comes with a mic. The remote itself feels cheaply made making me wonder how long it will last in particular the slider, but I had no issues with it during my time with the HM2. The flat cable also feels cheaply made and long-term reliability is a concern, but neither cord posed any problems, save some tangling issues with the flat cable, during testing.
    Sonically the HM2 meets the goals of having punchy bass as well as a kind sound that is not harsh or fatiguing. I tested the HM2 both amped an unamped.
    Unamped: With a sensitivity of 104 dB SPL / mW the HM2 is easily driven by portable devices and my iPod touch remained at the 50% volume level for most of my listening. The HM2 is detailed enough unamped to reveal the echoes in Peter Murphy’s My Last Two Weeks on the Love Hysteria album. The bass rumbles, treble is clear, and the midrange stays in check most of the time. I did find that the HM2 sounds tinny from the sub-bass to 1 kHz making the midrange sound unnatural at times. In Chick Corea’s Three Ghouls, Part 1 from the Ultimate Adventure album, is enjoyable and fun, but the woodwind instruments sound flat and lack the detail to bring out the sound of the air flowing through them. On other tracks like Kate Havnerik’s So:Lo on the So:Lo – Single, the HM2 sounds enjoyably. The bass is deep and impactful without drowning out vocals and the treble. I would say that the HM2 sounds better with clean and bassy tracks like jazz and electronic.
    Amped: Playing pink noise immediately reveals how bassy the HM2 is. The lower registries are definitely emphasized with obvious bass boost and midrange unevenness. Musically the HM2 becomes more alive amped. The bass tightens up and the soundstage moves up making this headphone much more up-front sounding than in the portable case. The kind nature remains intact and the HM2 is not fatiguing amped, but perhaps too bassy for some. Listening to Quentin Durardin’s 1977 track from the Putumayo Presents World Yoga album, the tinny midrange is easily discernible. The lack of reverberation and abundance of coloration in the midrange makes guitar tracks like this hard to listen to. They sound unnatural. Not to say one could not listen to tracks like this, but if the HM2 is compared to more neutral headphones obvious signs of the colored sound signature become apparent. This is one reason amping a headphone is important even if it can easily be driven by a portable device. Doing so often reveals the true sound signature while portable listening tends to hide some of the more delicate and hidden features of the sound signature. Surprisingly this headphone sounds great listening to The City of Prague Philharmonic’s Sute for Orchestra No. 1 in C Major, BWV 1066: on the Sunday Morning Classics: Sunday Morning With Bach album. The bass is definite and clear. The midrange is fun and engaging with clarity on the violins and harpsichord.
    The HM2 did work with my XBOX ONE stereo adapter so it can be used as a gaming headset. The sound during gaming was rendered full with the bass emphasis. The mic volume both via phone and XBOX was very faint. The resting position of the mic locates it too far away from the mouth leading to the poor mic volume. I think the mic is decent, but due to its location, is not ideal for conversing. I would like to see the mic functionality reviewed by Brainwavz and enhanced so it sounds more clear and louder during calls or gaming.
    It should be noted that the HM2 is sensitive to earcup position and the sound signature changes as the earcups are moved. The seal is also very important for clean bass reproduction. If the sound signature is not to your liking move them around a little and see if that clears things up.
    Brainwavz meets their goals of producing a very listenable headphone with thought out bass emphasis. The around the ear seal is excellent making them one of the most comfortable headphones I have worn, but it should be noted that my ears are small and larger ears may find the earcups tight. Aesthetically the HM2 is clean and well-built although a headband pad would be awesome! The remote is easy to use and functions perfectly. At $49.50 the HM2 is a great headphone especially for bass lovers and people that want something that is portable without major compromises.

    Brainwavz HM2 Review
    Brainwavz describes the HM2 as a pair of headphones that boast a smooth sound with punchy bass tuned to give a comfortable and enjoyable sound experience, making them suitable for all genres of music. Brainwavz is positioning these as budget headphones priced at $50. Personally, I haven't found a pair of headphones at this price range that I can consider a decent offering. So let's put the HM2 to the test and see if these can exceed my expectation.
    The HM2 was provided by Brainwavz free of charge in exchange for my review.
    Specifications and Features:
    ·         Drivers: Dynamic, 40 mm
    ·         Rated Impedance: 32 Ω
    ·         Frequency Range: 10 Hz ~ 20 kHz
    ·         Sensitivity: 104 dB at 1 mW
    ·         Maximum Input Power: 100 mW
    ·         Plug: 3.5 mm, gold-plated
    ​·         Detachable Cables: 1.2 m Cable with In-Line Microphone & 1.2 m Flat Cable
    ​·         Compatibility: iPods, iPhones & iPads, MP3 Player, Computer & Laptops, other audio devices
    ​·         in-Line Microphone: Multi-function Single Button, Microphone, Phone Call Control, Audio Player Control

    What's in the box?

    The HM2 packaging is simple and straightforward; inside the box you'll find the headphone case made of tough fabric. The black-red colour scheme works well for this case and keeps the illusion of smaller than that the actual size. Not as compact as a V-Moda M100 case but it's small enough not to take too much space in a backpack. Unzipping the case reveals the HM2 headphones and the two included cables along with the warranty card.

    Build Quality, Fit, and Comfort

    Initially, I was expecting a somewhat mediocre product which is usually the case in the $50 price bracket. To my surprise, the HM2 is considerably well-made. For its size, I consider the HM2 to have a slightly heavier construction than most in its category. Aesthetically these headphones are modern-looking with minimal moving parts. The matte plastic material is a clever choice for eliminating problems found in headphones with glossy finish -- fingerprints and smudges. The design is quite restrained with the black-grey combination and minimal chrome accents. Like the Beats Solo 2, the HM2 features  removable cables, foldable hinges to allow compact storage, and a sliding mechanism to adjust the headband size. However, the ear cup adjustment differs wherein the Solo 2 pivots on the cup while the HM2 pivots on the foam pads - similar in principle and keeps the ear pads secure on the user's ears. The ear pads seem to be easily removable but I'm not sure if Brainwavz offers ear pad replacements. Fortunately, there's a 24-month warranty so worn out ear pads shouldn't be a problem at least during warranty period.
    There are two cables included, a straight flat cable and a rounded mic with remote cable. I find the latter to be the better cable in terms of build quality, looks, and functionality. As per my phone compatibility tests, the mic works well with no complaints from the person on the receiving end. Voices were reasonably clean and audible. The one-button remote worked perfectly fine with Android and IOS functions. The music player for both platforms were compatible with the HM2. There is also a volume slider which comes in handy when you need to change the volume quickly. Personally I keep the volume slider at full stop when listening to music. This is because there's an inconsistency in L-R balance when adjusting the slider. Despite this problem, I still find it quite useful as it allows easy access to volume adjustment when you need to listen to someone or your surroundings.

    The headband adjustment is a sliding mechanism but unlike most headphones in the higher price brackets, the HM2 does not feature calibrations/markings to indicate the steps on the adjustment. However, there is a satisfying click on every step of the adjustment which compensates for the lack of markings. While I don't have a problem with the adjustment, the headband seems to be bigger than your average size head. This is the very first headphone that I didn't have to extend the headband and I believe this can pose a problem for people with much smaller heads than mine. There is no cushion nor padding on the underside of the headband. At first I thought this will surely cause discomfort on top of my head but to my surprise, there was no sense of discomfort on my head even after 2 hours of usage.
    The ear pads are ok in terms of softness but not very breathable. They can easily get too warm when used outdoors on a hot summer day. I also find size and shape of the pads are on the smaller side of an over-the-ear headphones and a tad too big for on-ear use. For me, these ear pads end up being over-the-ear but my ears just barely fit inside the cups and slightly touches the drivers causing slight discomfort after an hour's use.
    Isolation is below average for me... I can easily hear my surroundings even when playing music at an average volume. The HM2 will not satisfy those who need better isolation from outdoor noises in traffic or crowded environments. These also leak sound considerably so using the HM2 in a library limits the listening volume to an absolute minimum.


    SETUP:   Ipod Touch 5gen / iPhone 6s / SONY Xperia Z3 Compact   --->  OPPO HA-2

    Brainwavz has clearly emphasised the HM2 sound -- smooth sound with punchy bass. There is acceptable presence across the frequency spectrum but the emphasis is more on bass. The sub bass goes deep with an impactful mid bass. But there's a slight problem in terms of control because it's a bit overly boosted.  Bass is quite loose coupled by decay that lingers a tad too long causing slight muddiness in bassy tracks such as Bruno Mars' Gorilla. In comparison, the Sennheiser Urbanite XL is a bit more tighter and faster with lesser bleeding into the midrange. The HM2 has more sub-bass and mid-bass hump which equates to more slam at the cost of muddy transition into the midrange. 

    The midrange of the HM2 is quite linear but leans more on the warm side. The emphasis in bass overshadows the midrange to the point where the lower midrange is quite hazy and too warm. The Urbanite XL sounds a bit more clearer in the lower midrange more so in the upper midrange. HM2 maintains a smoother upper midrange nullifying any sign of sibilance even from Taylor Swift's This Love. As a result, one can blast the HM2 as loud as he can and sibilance won't be an issue. Excellent for pop music and outdoor listening. The transition from midrange to treble has acceptable clarity and detail despite the smoothness that prevails in the higher frequency. Unfortunately, the clarity and detail can become veiled with bass heavy tracks. This is prevalent in One Direction's End of the Day wherein the sub bass just overshadows the midrange and treble. In general, the top end sounds a bit airy with acceptable extension given that the track is as clear as Train's Drive By. HM2 treble is a bit lesser in energy than the Urbanite XL but a bit more extended than the Sony XB400. Soundstage and imaging are good enough to eliminate congestion although they are probably far from the best in the portable closed headphones category.

    Despite the limitations in HM2's sonic performance, they can still be an enjoyable pair of portable headphones when used under the right conditions. They sound a bit better when outdoors because the perceived bass emphasis is reduced. A listener tends to increase the volume than usual when outdoors so this will allow for the HM2's midrange and treble to be more apparent in the presentation. Under these conditions, the HM2 can be an enjoyable listening experience that boasts a smooth sound with punchy bass. Good for pop and electronic music.



    The HM2 is an average portable headphone if used as a full-time day-to-day gear. These are not the best for indoor use where the environment is quiet enough to reveal the headphone's inclination for bass at the expense of the rest of the frequency spectrum. Under the right conditions when outdoors, these can be a good daily driver if you like to listen at loud volumes and don't give much importance to isolation. Overall, a decent product from Brainwavz for half the price of most comparable offerings in the market today.
    I would like to thank Pandora and Brainwavz for making this review possible.

    Brainwavz HM2 Review

    Brainwavz is a brand that I have had quite a lot of experience with, having reviewed quite a few of their products. When they came out with the HM2, I was rather intrigued and curious as to what they could do with a budget headphone for just a mere $50. With many excellent choices in the $50 range, the HM2 would have to be a great product to stand out from the crowd. A quick visit to the Brainwavz page for the HM2 reveals a nice looking headphone which looks rather well, but let’s get on to see just how well the HM2 really did. Since the target audience for the HM2 is likely the average person, I will refrain from using fancy terms and make this quite a simple review. 
    **Disclaimer** The Brainwavz S2 was provided to me free of charge by Brainwavz in exchange for an honest, unbiased review.

    Packaging & Accessories

    The HM2 comes in a rather plain and standard Brainwavz box that their HM5 came in as well. Inside the box is a case and a warranty card. Upon opening the case, you will be greeted with the HM2 and 2 cables, one with an inline remote and one without. Both are 1.2m long and one is flat and tangle resistant while the other (the one with the remote) is your standard round cable. Both are rather high in quality. The one with the remote comes with a sliding volume control, which means that you can control the volume on whatever device you use, not just Apple. The case is one of the better ones that I have used, very sturdy, but easy to use.

    Specifications & Design

    Here are the specifications, I personally don’t pay much attention to this, but you can use it as a point of reference if you want.
    ·         Drivers: Dynamic, 40 mm
    ·         Rated Impedance: 32 Ω
    ·         Frequency Range: 10 Hz ~ 20 kHz
    ·         Sensitivity: 104 dB at 1 mW
    ·         Maximum Input Power: 100 mW
    ·         Plug: 3.5 mm, gold-plated
    ·         HM2 Headphones
    ·         Hard Carrying Case
    ·         1.2 m Flat Cable
    ·         1.2 m Cable with In-Line Microphone
    As you can see, the drivers on each side of the HM2 are 40mm dynamic ones. The HM2 is rather light and feels relatively well built. The plastic didn’t feel cheap and tacky but actually quite sturdy. The headband has quite a bit of flexibility and overall, the headphone should be able to take a few knocks and still survive. The headphone is foldable and able to fit into the case, which makes it a lot easier to take to places.
    Comfort is just ok, not great but not too bad either. They get a little stiff on the ears after a little while. Despite the earpads looking relatively large, they are not big enough to go over my smaller than average ears. The headband also has no pad, so that feels a little uncomfortable as well. They sit a little on my ears and as a result, they start to hurt after around an hour.
    Isolation is decent, they block out some exterior noise, but not enough for you to take them on a plane or busy public transport. I’m wearing these while typing this review on a mechanical keyboard and the sound from the keyboard is very easily audible even though the HM2 is on at volumes slightly above my normal listening volume.  

    Sound Quality

    I will split the sound quality section into a couple of sections, the bass, midrange and treble.


    The bass is probably what most people will be interested in given that its target audience is the general public. It is definitely bass heavy, if you like Beats headphones, this is quite a good Beats Solo replacement at a much lower price point. They may not be as blingy as Beats, but the bass from these sound just as good. The bass is very strong, both the mid bass and sub bass. It does sound a little bit muffled however. The bass is a little bloated and bleeds a little into the midrange.


    The midrange is undeniably warm, but not overly so to many people. Those who come from Apple Earpods will find these slightly warmer and that it has a better mower end performance. Vocals sound quite warm, but the clarity is still acceptable. Instruments sound a little too warm. There was no vocal sibilance at all, which is good to see. The main issue I found was that on bass heavy music the midrange tended to be a little bit overpowered by the somewhat boomy bass.


    The treble is smooth and very relaxed, it will be excellent for people who are sensitive to treble or just prefer a more relaxed sound signature. The treble extension is ok, it rolls off a little earlier than I would have liked, but it is not too bad. Those who like to blast music at high volumes will enjoy the complete lack of sibilance in this headphone. Even when I pushed it to very high volumes, I did not detect any harshness in the top end.

    Soundstage & Imaging

    The soundstage and imaging on the HM2 is nothing special, probably just around the level of the standard Earpods that you get with an Apple device. Stage is quite small and imaging is decent, but not that great.

    Detail & Clarity

    In case you haven’t grasped it yet, the HM2 is not a detail or clarity oriented headphone, it sounds very warm and loses quite a lot of detail and is quite boomy. The clarity is not very good, both instrumental and vocal.


    After reading this review you may be lead to believe that the HM2 is not a good choice, but this is not true at all. Despite it being behind other choices that are good in this price range, it is a fun and bass heavy headphone that will appeal to many people who just want a stylish, decent sounding headphone for a reasonable price. I would recommend the HM2 if your price range can’t be stretched to over $50 and you are looking for something that is simply fun and looks nice.

    Brainwavz HM2: Good-looking. Inexpensive. Needs EQ.
    Written by nmatheis
    Published Dec 9, 2015
    Pros - Lightweight. Comfortable. Compact. Inexpensive. Deep, powerful bass. 2 year warranty.
    Cons - Needs EQ. Deeper ear cups would be nice. Headband a bit on the big side. Volume slider could be smoother.



    Brainwavz is a company well-known on Head-Fi for budget-fi IEM with good sound, great accessories, and some quite unusual designs. I was introduced to Brainwavz when I purchased my FiiO X3 Classic from MP4Nation. The original S-series IEM, the S1, was included as a bonus with my X3 pre-order. With their unusual color scheme, flat cable, chunky strain reliefs and y-splitter, and all-metal housing, the S1 were quite different from most of the IEM I'd owned up to that point. I enjoyed them for a fun, v-shaped sound, although they were a bit ragged up top. Then along came the S5. I read pretty good things about those, so I picked them up. With big bass and a warm low end and plenty of sparkle up top, I enjoyed the S5 even more than the S1 as a fun, party-time IEM. Next came S0, which I also heard good things about. I picked it up, as well, knowing that they were taking the S-series in a new, darker direction. These weren't IEM I'd choose for fun, they're what I'd choose for relaxing in front of the fire - warm, dark, and smooth. Finally along came the S3, the most neutral (and seemingly controversial) member of the S-series. I mention all this as a prelude to my review of the HM2 just to give you a feel for my history with Brainwavz.
    Of course, Brainwavz also makes headphones. The HM2 is the first headphone from Brainwavz I've had the opportunity to listen to. I'll just let you know right now that it isn't something I'd typically choose for myself, but when the review opportunity came up for a street style headphone with a smooth sound signature and good aesthetics came along. Well, I thought to myself, "Hmm, Nikolaus. You've been enjoying IEM with a smooth signature lately. You like headphones even though street style phones aren't typically your thing. Maybe Brainwavz made them more comfortable and sound better than other street style phones you've tried. And they do look good..." So, the deal was sealed, and I said yes.
    If you're one of those types who can't sit trough a full review, let me just tell you some of the answers right now. The smooth sound signature was a little too bassy for my taste, and I found cutting a wide swath across the bass helped tremendously in enjoying these. Comfort level was good, allowing me to wear them for long periods even while wearing glasses. Isolation is okay. Aesthetics are pleasing, especially for street style phones in this price range, which can look pretty gaudy. This means I don't look like a goof wearing them out and about, which the sound signature is best suited for. Build quality is better than average, so they're not going to fall apart on you quickly. And finally, they fold up quite small and are well-protected in their hard case. So, if you're looking for a pair of street style phones to keep in your go-bag and don't mind a quite bassy sound signature, these might just be a good choice for you

    There is no financial incentive from Brainwavz for writing this review. I am in no way affiliated with Brainwavz, and this is my honest opinion of the HM2  I would like to thank Brainwavz for giving me a chance to test drive the HM2, and I hope my feedback proves useful for my fellow Head-Fi members as well as for Brainwavz.


    I'm a 43 year old father who loves music. While I listen mostly to electronic and metal these days, I do listen to a wide variety of music - from electronic (Autechre, Boards of Canada) to modern/minimalist composition (John Cage, Philip Glass) to alternative rock (Flaming Lips, Radiohead) to jazz (John Coltrane and Miles Davis) to metal (Behemoth, King Diamond) to classic rock (Eagles, Rush).  
    I'm primarily a portable audio enthusiast. My portable music journey started with the venerable Sony Cassette Walkman and then progressed to portable CD players, minidisc recorders (still have my Sharp DR7), and finally on to DAPs like the Rio Karma, iRiver IHP-1xx, iPod 5.5, iPhones, and the newer crop of DAPs from Fiio and iBasso. Being a portable audio enthusiast, I typically listen with IEMs but am enjoying listening with full-size headphones and desktop gear more and more.
    As with a lot of people my age, I've got some hearing issues.  I've got mild tinnitus and suffer from allergies, which can affect hearing in my right ear. I'll admit it, I'm not blessed with a pair of golden eas.  That said, I've been listening to portable gear for a long time and feel confident in assessing audio gear - just wanted to be transparent up front.

    Typical Brainwavz packaging and accessories. 
    Hard Case Slips Out
    Containing the HM2 & Accessories


    In all, you get
    1. HM2 Headphones
    2. Hard Carrying Case
    3. 1.2 m Flat Cable
    4. 1.2 m Cable with In-Line Microphone

    Some general thoughts on the accessories package. The hard case is nice and fairly compact, so you can throw it in your go-bag without taking up too much precious space. One nitpick is that the mesh pocket isn't very good at containing the cables. After carrying the case around, I typically find that the cables have made their way out of the mesh pocket and are floating around in the main compartment. Having two cables is nice. The round cable is my preference because I don't like anything in between my cans and source but wire. If you're into a remote, the flat cable is for you. It's one of those one-button remotes, so you'll be clicking it a lot to pause/play, ffwd/rew, and accept/end calls. An interesting choice was the inclusion of a builit-in volume attenuator. This means you can control volume from any source, since it doesn't rely on any communication with your source. The downside is that unlike the HM2 themselves, the volume slider isn't a smooth operator. It sticks a bit, making volume adjustment a bit jumpy. If you're anything like me, you'd probably rather just use the volume buttons on your source anyway. 


    As usual, I'll walk through the various design and ergonomic features of the HM2 in pictorial format below, pointing out what I like and where I see room for improvement.
    Folded, the HM2 are nice and compact, and I like the subtle chrome accent.
    Unfolded, the HM2 are still a quite compact headphone.
    So the main nitpick to point out in this photo is that the HM2 lacks any kind of headband padding. This isn't as big of a deal as it would normally be because the HM2 are mainly held in force by clamping force, allowing the headband to rest very lightly on your head. A little padding would be nice, though. And despite relying pretty much solely on clamping force for stability, they don't actually clamp hard enough to be bothersome. Besides the sound signature, I don't usually like street style phones very much because I wear glasses, and they usually put too much pressure on the arms of my glasses and cause discomfort. Not so with the HM2. They were surprisingly comfortable. My second quite minor nitpick is that I wish the jack for the cable were set just a bit higher up, as the connector tends to rub against my shoulder when I turn my head. This causes some microphonics of a sort that I find unpleasant (kind of like nails on chalkboard for me), so I'e learned to tilt my head up just a bit to avoid this when looking over my left shoulder. This is probably just a weird Nikolaus thing, so I'm not going to ding the HM2 for it.
    So what do I like? As mentioned above, I find them quite comfortable especially when tooling about in a baseball cap. Even without a cap, they're comfortable enough for me to wear for extended periods despite the lack of padding. I also like the nicely toned-down street style aesthetics.
    Close up of the hinge mechanism and the headband adjustment mechanism.
    My one nitpick here is that I wish there were some markings on the headband to allow me to quickly get back to just the right size. Other than that, no complaints here.
    The cups fit my smallish ears okay. I prefer a larger cup, but these are pretty comfortable and thankfully don't heat up too much. My ears do touch the drivers, though. I'm sensitive to that, so this does start to bother me after listening for awhile. Deeper cups would be appreciated. The cups are secured to the headband with a ball and socket type joint, allowing them to swivel a bit in all directions. This allows them to automatically find the right fit for your head. 
    All in all, these are a pretty darn good design for inexpensive street style phones. 
    FYI: I mainly listen to experimental electronic and metal and mainly used those genres to evaluate the HM2, along with a bit of classic rock thrown in for good measure. Since these are street style phones designed primarily for on the go listening, I just used my iPhone 5s for this review . No fancy-schmancy DAPs this time. 
    Okay, the only sound descriptor Brainwavz provides for the HM2 is "smooth". That could mean different things to different people. Since they're street style phones, I was expecting a bass-enhanced sound with a smooth upper end and Brainwavz didn't disappoint there. These are definitely bass-enhanced. A bit too bass-enhanced, in my opinion. Bass-enhanced to the point where the bass starts to mask the upper end, preventing me from hearing as much as I'd like up top. I tried for several days to reconcile with this sound signature before deciding it just wasn't for me. Not only was the upper end masked, the bass was too slow and plodding. So, I eventually broke down and broke out the excellent Equalizer iPhone app and applied a very simple EQ adjustment that helped me enjoy the HM2 much more. For those of you who don't know the Equalizer app, it's basically a 7-point parametric EQ. My starting point for making these a clearer sounding headphone is to apply -5dB at 20Hz with Q=0.375. With this setting, the HM2 are still bass-emphasized but the upper end comes out to play making them sound more balanced and lively to my ears. If you want more bass but still not as much as the default sound, set the EQ to -2.dB. If you're more of a purist or are listening in quiet environment, you might want set the EQ a few dB lower. If you purchase the HM2, I highly recommend playing with the EQ to either knock down the low end or bump up the upper end or both, depending on your preference for a flatter or more v-shaped sound signature.
    ​So now that I've got the basic EQ applied, I've got a nice bass-enhanced sound signature with a clearer upper end. Soundstage is also opened up compared to the default sound signature, which felt a bit claustrophobic to my ears. It's a nice on the go sound signature, which is exactly what the HM2 are intended for.

    ISOLATION: Average. It's horribly rainy right now in Portland, OR. I know, surprise, surprise, right? Anyway, it's not a good time to go out and walk around the neighborhood, so I tested out isolation by washing the dishes while my wife was wrangling my two wee yet surprisingly loud boys. If they were in the other room, they were nicely dulled. If they came in the room with me, I could hear they were talking to me but couldn't understand them until I paused the music.
    POWER REQUIREMENTS: With the stock Music app on my iPhone, 50% volume was pretty darn loud.
    So what do I think of the HM2? My initial reaction was a mixed bag. I liked the design and aesthetics but wasn't enamored with the sound, which took the bass-enhanced sound signature just a wee bit far for my taste. After reigning that in with a bit of EQ, the HM2 became much more enjoyable for me. For those of you who like a lot of boom-boom, I can see you enjoying the HM2 for an inexpensive pair of on the go phones. For those of you who enjoy a little boom-boom, you'll need to break out the EQ. If you're after a reference signature, walk away now...
    What would make these better? Throw at least a thin layer of memory foam on the headband, make the headband just a bit smaller, make the cups a bit deeper, and reign in the bass a bit. Make those changes, and I'll tack on another 1/2 to 1 star depending on the implementation.
    I hope you found this useful and would like to give a hearty thanks to @Salsera at Brainwavz for giving several members of the Head-Fi community a chance to review the HM2. I'm a Brainwavz fan and look forward to seeing what they cook up for us in the future. Did someone say budget-fi planars? That would be awesome, Brainwavz. C'mon, just do it!

    The Lightest Touch

    Pros - Super Light Weight, Folds Well, Nice Hard Carrying Case, Easy Going Sound Signature
    Cons - Too Big for My Small Head, Slight Sound Veil/Echo
    **Disclaimer, I would like to thank Brainwavz for providing me an early sample of the HM2 for review*


    Drivers: Dynamic, 40 mm Rated
    Impedance: 32 Ω
    Frequency Range: 10 Hz ~ 20 kHz
    Sensitivity: 104 dB at 1 mW
    Maximum Input Power: 100 mW
    Plug: 3.5 mm, gold-plated


    - HM2 Headphones
    - Hard Carrying Case
    - 1.2 m Flat Cable
    - 1.2 m Cable with In-Line Microphone

    The carrying case is quite nice; it is clearly a safe spot to store the HM2.  The case is designed well and has a premium feel that has plenty of room for the included cables as well.

    I love detachable cables, it does a few things. First, it is a safety net when/if you snag the headphone cord on something.  Instead of breaking the earphone, the cable will just pop out and you can just put it back in again.  Second, it is great option for those looking to change up the cable to something else.  Either be a longer or higher quality or be designed for a specific purpose.

    I noticed right away how amazingly light weight they feel in the hand.  I don’t think I have ever held a headphone of this size that weighed this little.  The Headphone itself is mostly covered in a soft, black plastic that is nice to the touch.  The HM2 feels solid enough to take a drop or two, while not fretting about breaking it, though for this review I did not test my theory.  The folding hinges are solidly built and show no signs of weakness. 


    Let’s just get this out of the way.  I am short, I actually wanted the username “Stumpy”, but it was already taken.  I am 5’4” on my tippy toes, so the rest of me am proportionally small, like my head.  So when putting on the HM2, even at the lowest setting, I found that they were just a tad too big for my head.  So the ear cups end up resting on the tips of my ears.  Luckily, like I mentioned, these are SUPER light, so the pressure on my ears is still very small.  I feel if there was some padding added to the underside of the headband, that it would help create a better fit/comfort for me.  The headband itself does not flex too much, instead relying on the rotating ear cups to help with the fitment.  The ear cups are on the firmer side, they allow the ears to breath, so they never become overly warm.


    These are designed for on the go and for that they do VERY well.  The lightweight build and their feature to fold up make them easy for on the move.

    Normally I would also test the microphone at this point, but unfortunately my sample unit had the cable with the mic mysteriously disappear.  Though knowing Brainwavz quality, I am sure it works extremely well without issue.  I will say that the standard cable hooks up and works perfect though.

    Bass – I like the lows, I like them because they are not bloated, muddy or otherwise unnecessary exaggerated. There is a touch of sub-bass in the distance and a tad of mid-bass, but both are nicely tame.

    Mids – Vocals have a laid-back approach, while not recessed, there does not seem to be much urgency.   The rest of mids continue to follow the easy going approach that started in the lows.

    Highs – The highs do not offend and roll off early, instead focusing on preserving enough detail without becoming fatiguing. 

    Soundstage – There is a slight narrowing feeling, I would not use the word congested, but there is not a lot of separation between the vocals and instruments. Also there is a slight echo that can faintly be noticed.

    Isolation – The HM2 will block a little bit of outside noise and does not seem to leak outwards. I feel if the ear pads were just a tad softer that it would help create a better seal and better overall isolation.


    *Overall Thoughts*

    The HM2 has an MSRP of $50 and for that price it has a lot to offer for value: Lightweight design, detachable cables, solid build, great carrying case and a smaller footprint due to their ability to fold.

    Sound wise, there is musical clarity that does come through, giving the HM2 a clear overall tone. Bass is mild, but still very much accounted for. Overall presentation is right on target for this price range.

    The HM2 is a good overall headphone that does a lot of things right.

    Portable offering from Brainwavz at a low price
    Written by peter123
    Published Feb 14, 2016
    Pros - Leightweight, practical on the move
    Cons - Muffled and overly bassy sound
    I would like to start with saying thank you to Brainwavz and Pandora for letting me checking out the Brainwavz HM2.
    The Brainwavz HM2 is available from Brainwavz Audio:
    I’m not in any way affiliated with Brainwavz.
    The only full sized headphone from Brainwavz that I own so far is the excellent HM5. It’s one of my favorite closed headphones with its very well balanced sound. I’ve also thoroughly auditioned the HM3 that I liked so needless to say I was very curious about how the HM2 would perform, let’s get down to it.
    About Brainwavz:
    Brainwavz is a well know company here on Head-Fi and this is what they say about themselves on their website:
    Established in 2008 with a goal to bring real earphones to real users at realistic prices -A SMALL START WITH BIG RETURNS
    Today the range spans across earphones and headphones, a new accessories line and the addition of inline controls for the booming smartphone markets
    The future sees the BRAINWAVZ team expanding to more new products, from new designers with fresh ideas - WE ARE HERE TO STAY, so keep listening out for us!
    At Brainwavz we have a simple mission, to produce innovative, high quality audio products with a dedicated focus on high-end sound at a realistic price. Our strength, success and product range is built on our unique relationship with our customers and users, a relationship that has produced a simple and obvious result. We give real-users real sound quality.
    About me:
    I’m a 43 year old music and sound lover that changed my focus from speakers to headphones and IEM’s about five years ago. At that time I realized that it wasn’t realistic for me to have all the different setups that I wanted and still house a family of four children and a wife so my interest turned first to full sized headphones and later also IEM’s.
    My preferences are towards full sized open headphones and I believe that also says something about what kind of sound signature I prefer (large soundstage in all directions, balanced and organic sound).
    My music preferences are pretty much all over the place (only excluding classical music, jazz and really heavy metal). My all-time favorite band is Depeche Mode although I also listen to a lot of grunge/indie, singer/songwriter/acoustical stuff as well as the typical top 40 music.
    I do not use EQ, ever
    I tend to value function over form within reasonable boundaries. 
    I’m a sucker for value for money on most things in life, Head-Fi related stuff is no exception.
    Built and accessories:
    The Brainwavz HM2’s are a dynamic headphone featuring a 40mm driver.
    It comes “only” in one flavor: black/grey color scheme with two different cables, one with mic and one without. The answer/call (same as play/pause) button and mic works great with my LG G3 phone.
    The HM2 has detachable cable with a standard 3,5mm connenction and actually comes with two cables: one flat without microphone and one round with microphone. I personally prefer the round one so that’s the one I’ve been using. The cable has a straight 3.5 mm connector. Although I personally prefer L-shaped (45 or 9 degrees) connectors this one seems well built and should hold up for a long time.
    The microphone seem to be of good quality and people can hear me loud and clear when using it to make phonecalls.  
    The build seems solid in the way we’re used to from Brainwavz. Although the material is almost exclusively plastic they still seem well build in general.
    The retail package is nice as always with Brainwavz and feels very good for a headphone in this price bracket.
    The accessories pack is decent for the price and includes the following:
    1 flat cable without a microphone
    1 round cable with a microphone
    1 zipped case to store them in when not in use
    The Brainwavz HM2’s are about average to drive and works fine even with LG G3 phone.
     Isolation is less than average for a closed headphone.
    Please note that Brainwavz has extended their warranty to last for 24 months (earlier it was 12 months) for all their products. Pretty impressive to me, let’s hope that other manufactures learn from this and offer the same in the future.
    The specs:
    Driver Unit
    Frequenzy range
    32 Ohms
    Cable lenght
    1.2mone with mic and one without

    Fit and ergonomics:
    The smallest head size adjustment on the HM2’s is actually too large for me. This combined with the fact that the headband doesn’t sport any padding at all makes them sit loose on the top of my head and wiggling slightly when I’m moving around. I’d also imagine that the lack of headband padding could make the uncomfortable for those with a bigger head than mine where the headband actually rests on the top of the head.
    As already mentioned the build is mostly plastic and this helps keeping them very light which I find to be an important feature on a portable can.
    The HM2 can also be folded together to a quite compact size and with the included travel case they're very convenient when travelling. 
    I’ve used these back and forward for the last couple of months and they’ve played for well over 100 hours. I’ve used them both around the house and when out and about and I haven’t really found any significant weaknesses in the way they’re designed.
    I’ve used them with my LG G3 phone and the CEntrance DACport Slim and they’ve worked very well with both of them.
    Demo list:
    Mark Knopfler – Sailing to Philadelphia
    Røyksopp (Feat.Susanne Sundfør) – Save Me
    Ane Brun – These Days
    Michael Jackson – Dirty Diana
    Metallica – Die Die My Darling
    The Peter Malick Group – Immigrant
    Eva Cassidy – Songbird
    Thomas Dybdahl – A Lovestory
    Norah Jones – Don’t Know Why
    Celldweller – Unshakeable
    Jack Johnson – Better Together
    Seinabo Sey – Younger (Kygo remix)
    Dire Straits- So Far Away
    Passenger – Let Her Go
    Lupe Fiasco - Deliver
    Morrissey – Earth Is the Loneliest Planet
    The overall sound signature on the HM2 is warm, smooth, intimate and bassy.
    The bass is the most noticeable part of the sound from the HM2. Unfortunately it’s more mid-bass than sub bass presence. The bass does also bleed into the other frequencies more than I would have preferred. The strong bass presence makes the whole presentation lack some air and overall sound is quite dark and a bit muffled.
    The midrange is partly overshadowed by the bass and female vocals feel distant while male vocals are a bit more forward (but still recessed) in the mix. The overall full sound gives a nice weight to male voices.
    The treble is nice and full without any hint of sibilance. Although the top-end sparkle’s not the most noticeable and the treble rolls of a bit earlier than I prefer I still find them to have a nice non-intrusive treble presentation.
    Clarity and micro details are less than average for a headphone in this price point. There’s also a bit of hollowness to the sound that I really don’t like.
    In all I find the sound from the HM2 to lack some excitement and be to warm and intimate for my preference.
    Please note that the comments in the comparison section are not in absolute terms but in comparison between subject A and B. This means (as an example) that if subject A is found to be brighter than subject B it does not necessarily mean that subject A is bright sounding in absolute terms. I hope this makes sense.
    Takstar Pro80 ($50) vs Brainwavz HM2:
    The Takstar Pro80’s are my all time favorite closed headphone and can be had for such a low price as $50 if you get them without the carrying case. Compared to the HM2 the Pro80’s has a much more airy presentation with better detail retrieval but also a brighter signature. The Pro80’s has about the same, or even slightly better, sub-bass extension but way less mid-bass impact and bloom. The overall balance is noticeable better on the Pro80’s.
    I find the Pro80’s to be more comfortable but its cable length makes it less ideal for portable usage.
    The Pro80’s are significantly harder to drive.
    Isolation is better with the Pro80’s.
    Superlux HD662f ($50) vs Brainwavz HM2:
    Compared to the HM2 the HD662f’s has a bigger soundstage in all directions. The overall sound is also much more balanced but also brighter.  The Superlux’s has better treble extension and none of them are prone to sibilance. Superlux has a bit less subbass and noticeable less mid-bass impact, they also have a much cleaner sound.
    I find the HD662f’s to be more comfortable but its size and cable length makes it less ideal for portable usage.
    The Superlux’s are significantly easier to drive.
    Isolation is pretty similar between the two.
    All together I find the Brainwavz HM2 to be a decent offering at its price. It has a nice build quality and the included two cables and the great case feel as a good accessory pack given the low price. Although the sound doesn’t hold up to the competitors in the comparison section and really isn’t my preferred signature I’d still say that they’re a good value as a total package for a portable offering with its leighweight and foldable design.

      Nice revew Peter! I share most of your thoughts on them. But they respond really well to EQ and can sound really good after some tuning! Guess that who would like to play with it is @Joe Bloggs

      Thanks! @leobigfield  . You know me, I'm not big on EQ :wink: I've got no doubt in my mind that Joe could make these really sing though.
