    Full review here:

    First of all, I must note that the version I got seems to be a newer one as it differs from the ones I've seen online. The box is different, the plug is angled and not straight, the nozzle filter is black and the included eartips are "hybrid-style" ones. So please take this into consideration as my impressions might be quite different, and so it seems, from previous MA350's reviews.
    There's a lot to like about these RHA model, and it's hard to find a weak point on them. The overall sound is on the warm side, rich and fun, and full through all the frequencies, with a slightly lively presentation.
    Bass is strong and punchy, but not lacking control. Sub-bass manages to reach deep and offers a fun rumble. There’s an extra mid-bass lift which makes the 350 sound fuller, but not overwhelming to offend the lower mids. Not as powerful and thick as the heavier sets such as the Dunu DN-23 and, fortunately, don't have the Brainwavz M5 annoying upper-bass 'hump'. Of course, there's no need to mention they're far from AF45 bass levels. A good comparison should be the VSD1-S, as both are very close both in quantity and quality terms, being the RHA just slightly boomier on times, but do share a very similar presentation.
    Midrange is very slightly forwarded at best, not recessed for sure. Neither dry nor too sweet, but do have a decent sense of fullness. Not as effortless as the above mentioned VSD1-S though, but yet a bit thicker than the ATH CKM500 (which have the edge when it comes to overall clarity and openness - not very surprising considering the open-design of the AT). Vocals are more forwarded and nicely positioned. Female ones aren't as sweet as with more mid-centered in-ears, such as the VSD1-S with their special coloration, but on the other hand, both male and female vocals are evenly positioned (something that the Vsonic were really lacking). However, both RHA and Vsonic are far from to the pricier RE-400, which offer a much more intelligent, coherent and, mainly, beautiful vocals reproduction. Anyway, considering the stronger bass and added highs, the MA350's midrange was nicely made and won't dissapoint with most genres.
    Following the lively signature, the highs are more prominent, very crispy and sparkly with a nice extension and very good clarity for the asked price. They are less forgiving than the smoother RE-400, and in a lesser degree, than the VSD1-S (which are already smoother within the Vsonic's budget line), but not sibilant or harsh unless used on higher volumes.
    Soundstage is quite good, wide and open with a right sense of air and separation. A very enjoyable and catching sound, indeed.

    Pros - Clean sound, highs and mids well responding with a good bass
    Cons - Harsh upper mids, and extremely poor build durability
    Reid Heath Audio is somewhat of a new comer to the world of audio. Their main branch, Reid Heath Ltd. is still not very big. However, their company represenatives were homley and their web page yells humble.  They are ambitious in getting the word out about their company from the looks of it. I recently spotted their company at an Apple store. Amazing isn’t it, what people with a dream can achieve. I would like to thank RHA for arranging the review samples and Warren for the recommendation.Now let’s take a look at their earphone.
    Read the review here:
    Unit Quality:
    -Utilitarian, light but well structured-

    The MA-350 boasts of its use of Machined Aluminum and it should. The driver housing, from the looks of it, is comprised completely of this material. Many companies obviously use Aluminum. But few use it in such a way that RHA did. Many will add designs, and plastics, and other things to the housings aluminum faceplate or body. This weighs the unit housing down. RHA goes utilitarian and gives you a light weight housing for the driver. It is very light, but isn’t exactly weak. I wouldn’t and haven’t actually tried to step on them but they seem to hold up well. Scratching the black faceplate wasn’t really an issue but I can see it happening.

    The cable however is really like many of the braided cables out there at this price point. Skinny, light, and flexible. However, this adds microphonics and feels a bit too weak. From the cable to the headphone jack feels a bit underwhelming.  The cable does also get kinks in it. It is still hard enough at sections to scrunch up. It is basically an ordinary cable at this range of headphones.

    Microphonics is the annoying sound made by cables due to a variety of factors.

    Yes (and the masses go wild!). This earphone has a problem with microphonics. I hinted at it with the cable part. But just like many ordinary cables at this range, it also has the problem that hits many other earphones.  The dreaded microphonics syndrome plagues it.  It is quite bad. I’ve had to awkwardly wear the cable over ear in most situations to escape it. I can usually not do this while at the desk for most earphones that have this. But the mere touch of the cable to my clothing would give me the plague. Sorry.

    Ahh yisssssss. Sibilance is another dreaded thing that we hate. It is the audible sound of s’s and many others. It is a demon of many heads.  Thankfully, RHA had slain the dragon with the MA-350’s. There are some times when it may arise. But those are mainly due to some sonic qualities of this unit (more later) and the track itself. For now, you may rejoice.

    Don’t want to hear Harley’s while you listen to music? Don’t want to let your friends know that you actually am sick with Bieber fever? Well then knave, carry on reading. In terms of blocking out outside noise, the RHA’s do perform below average. Keep in mind that average is already quite good. At a ‘decent’ volume, some annoying vehicles and etc could still be heard. It may be due to the thin aluminum. As for personal isolation, these keep your secret nice and safe. As long as the buds are in properly that is. Pop them out, and they do have enough sound coming out of them when you are jamming that anyone will ‘know’. I mean who doesn’t know “BABY! BABY BABY! OOOOO!!”

    I will admit that I do not prefer using these for the sole purpose of microphonics. Wearing these over ear gives a weird cable loop that extends a bit too far. Besides that, there is nothing extra ordinary to note.

    iPod/pmp is fine. Very easy to drive these things. It’s impedance is low so watch out.

    Sound Quality introduction:

    These RHA MA-350 go for $39.95. But how do they sound? Well, quite above average. You were expecting another one of my famous out bursts huh? I would say it is quite a lollipop.

    -holds well, not too fatiguing, done well-

    The high frequency response of these held out quite admirably. Most earphones at this price range make the mistake of giving a consumer highs and doing it wrong. Most don’t even bother giving you a high frequency range anymore. This means very sharp highs that want to make your ears bleed or none at all. I attribute this to the problem of teens today. The RHA’s however do give you a good high. Not perfect but good. It hits high and holds. It wouldn’t be a silky smooth high frequency response but is quite admirable. There are a few times when the highs doe escape their path and lead to some bright moments though.  It is a good addition to the MA350 but I do wish for a smoother high frequency next time.

    -right in the middle, sweet, fatiguing after a while, dynamic-

    So first we start with the vocals. I would not say that the vocals are forward or laid back. Background instruments are a bit louder than the vocals so you can say that they are. But they aren’t pulled back enough for me to say that they are really a backup. The energy is still enough that you can still enjoy it. The vocals are very dynamic. They cover a variety of roles and don’t become like flat soda. There is a bit of a spike in the upper mids that do cause fatigue though. These are some bursts of this spectrum that adds to the fatigue sadly.

    The mid range instrumental spectrum is done well.  Smooth and dynamic are the words I would give it. They do become a bit louder than the vocals on general (unless the track differentiates and makes it differently).  So they do become a show stealer many times. Instruments have above average separation and clarity. They are good sounding. But the problem with the vocals comes back. That little spike in the upper mids that just gives a knock on fatigue lane.

    -punchy but without orthodox impact-

    For earphones at this range, a bassier earphone is always welcome. The MA 350’s give you the bass of many other earphones but with a noticeable less amount of impact. It is still there but much more subtle. You are getting the bass response but without the actual ear drum thumping signal, or most of it that is.  This is a feature more often found in higher tier IEM’s. Glad that it is there.

    The sub bass and mid bass also share qualities that the bass response gives. They are there is very good proportions. It isn’t extended too deeply, not too little, and not too much.

    The MA-350’s do get a bit fatiguing after a while, but it has a nice sweet dynamic sound. It isn’t as musical(long term enjoyment) as many earphones though. There really wasn’t a set genre that I could jam too without comparing the MA-350 to other IEM’s that give you a very fun sound. However, this right here is another feature of higher end IEM’s. It’s just that the MA-350’s neither fall on the musical side, nor a good replica of higher end sound.

    Cons - Mids are slightly recessed, don't stay in your ear too well, cable noise
    First off, I would like to thank RHA for sending me the MA350's for a review! 
    I am going to get right into the review now. 

    Driver size: 10mm Mylar
    Frequency range: 16-22,000Hz
    Impedance: 16ohms
    Sensitivity: 103dB
    Rated/max power: 3/10mW
    When I first received the MA350's and opened them, the packaging was good. A rectangle cardboard box with a plastic cover in the front, displaying the headphones. On the back you can see the specs of the MA350's, and a paragraph on why they were designed. The packaging is great for a $40 earphone. When I opened the box, inside I found a users guide, small and large tips, (The medium size tips are already on the MA350's) and a carrying case. It doesn't come with lots of accessories, but that isn't really an issue. 

    Accessories: The MA350's come with 3 sizes of tips. Small, Medium, and Large. They also have a nice, velour type carrying case. The carrying case is black. It is plenty big for the earphones. You couldn't fit an iPod in the case, but if you need to, possibly an extra earphone or two. The case has a drawstring on it, so you can tighten and loosen the case if needed. One thing about the case though, is how it attracts dust and pet hair. I dropped the case on the floor just to test it out, and a lot of dust/ pet hair got on it. The pet hair was easy to get off, but the dust was nearly impossible to get off. Unless you plan to show off the case, it shouldn't really be a problem. 

    Build: The build quality on the MA350's is very nice. Every time I hold them in my hand, I can't help feeling how smooth they are. The MA350's are made out of Machined aluminum. It is very solid. I have not found any faults in them at all, and they seem like they will last a very long time. The earphones come with a 3-year warranty. Unless put under a lot of stress, the MA350s shouldn't break under normal use. The cable is a well built, braided cable. It seems nice and strong, and I don't think it will break anytime soon. But having the braided cable, the cables rubbing is pretty annoying. The tips are kind of difficult to get off, so when taking them out of your ears, a tip shouldn't fall off. The warranty includes complete coverage for 3 years from the date of purchase, so if you manage to break them, RHA has you covered. 

    Appearance: The MA350's from the back are all black, with the RHA letters on them, in a nice white color. From the front, they are a nice silver aluminum color. The two colors go together very nicely. When worn out in public, I didn't get many looks or stares. But when paired with a bright outfit, the earphones compliment the outfit very nicely. One thing I thought could be different color was the Right and Left markers. The "L" and "R" markers are black, on top of the same color black, which in dim light, made it very hard to see which is which. The ear tips are black. The overall appearance, is simple, yet stylish. 

    Comfort: As with most earphones, comfort is subjective. I found the MA350's to be comfortable for around an hour, until my ears started to become a little sore. The MA350's really didn't stay into my ear too well, falling out a little too frequently, causing me to not get a good seal. When I could get a good seal, the isolation was average for an IEM. The comfort/ isolation may be better with different tips. Overall, the comfort / seal wasn't up to par. 

    Sound: The sound on the MA350's is pretty good. I wouldn't say the best bang for your buck at $40, but definitely worth the full retail price. 

    Bass: The bass is very good. There is a decent amount of Sub-bass and a nice amount of Mid-bass. You will get the nice rumbling lows, and plenty of punchy-ness when you need it. You won't find any muddiness or bloated bass here. The bass play's in nice with the other frequencies, by not overpowering the mids or treble. But, there isn't a large enough quantity of bass for these earphones to be deemed a bass-head headphone. So bass-heads should look elsewhere.   

    Mids: The mids are slightly recessed. Just slightly. Not really enough to called be a v-shaped earphone, but the mids are slightly recessed.

    Treble: The Treble is pretty nice. It is bright and sparkly. The is a little bit of sibilance, but not much. The detail and instrument separation is very nice. The soundstage is on par for a $40 IEM. 

    Overall, the MA350s are a great pair of earphones. Nice bass with a punch to them, and a bright, sparkly Treble. A very good build too. Sightly recessed mids and annoying Cable noise keep these earphones from getting a 4 star review. If you need a nice sounding, portable IEM for around $40, the MA350s are a great choice. I would recommend them for just that.

    RHA MA350: Something to Trumpet!
    Written by a_recording
    Published May 27, 2013
    Pros - Durable metal earpieces, comfortable fit, deep bass
    Cons - Tangly cables, lacks a little clarity, driver flex
    I'd like to think RHA for sending me these earphones for review.
    Along with the summary below, I have posted a Youtube video review of the MA350. If you like the video, check out my channel for more reviews :)

    The MA350 has an interesting build, with a reverse horn / funnel shape. This is actually the opposite of a horn speaker design in principle, and means that the MA350 fits very comfortably in the ear. The aluminium in the earpieces is very welcome and makes the earphone feel quite durable, but the fabric wrapped cable is tangly and microphonic. Luckily the MA350's are well suited for over-ear use. The strain reliefs seem a little flimsy. On both the RHA 350 and RHA 450 I experienced quite a large degree of driver flex which makes me nervous.
    The MA350 is a very bassy earphone but the peak in the highs prevents it from sounding too congested or muddy. Bass is well rounded, goes very deep and is very visceral. The highs are generally soft except for a peak that lends energy to vocals. Overall definition is quite good, though they are not the fastest sounding earphones. They have an intimate soundstage but good instrument placement within that stage.
    Because of the comfort of the earphones and the engaging sound, I think these make a good everyday pair of earphones - though perhaps they are not suited for critical listening. You definitely must like your bass to like these earphones, but they are a great little gems for the price. Driver flex is my biggest worry about these earphones, otherwise I would be giving these 4 stars.

    Amazing little IEM with a great sound quality and signature, and a bargain at the MSRP. Must get if you're looking for a quality daily beater.

    Pros - Good quality bass (esp. the subbass); small, funnel shape ensures comfort for longer commutes; midrange and treble are still high quality
    Cons - Cable can get tangle if not stored in the cloth pouch; tips could be a bit stiff and tight the first time around; forward bass might not be for some
    This isn't really a straight copy from my blog post here, but it still is a copy. More pictures and more in-depth look is in this 5-part review-journal.
    ==][==Classy Commuter: Final impressions of the RHA MA350==][==​

    A huge thank you to Reid Heath Audio and warrenpchi for making this review possible, and moreso the person in charge of contacting me. Without them, I wouldn’t have heard this marvelous IEM: the MA350

    Accessories and build quality

    You can check out here for more meandering on the package, but it has the usual package of IEMs: two more pairs of tips at small and large size, and a cloth pouch. Build quality is actually good: aluminium shells and ample strain relief on the speaker end, cloth-sheathed cable that’s not memory-prone, but sometimes can tangle if you’re not using the pouch, and ending with a gold-plated straight jack; although I find that the strain relief on the jack to be too soft to my liking.

    The IEM tips are very good actually but err on the side of caution when you’re taking them off, lest you’ll end up like me with a torn tip. I’ve mentioned this to them and it is by design. Thankfully they sent me another set of tips and also this picture on how they recommend to put in the tips back.

    And as can be seen there, it also has a narrow nozzle and circular shell, making it possible either to wear it cable down or cable up, where you wound the cable up above your ear before putting it in. I recommend wearing it cable up since the microphonics is not too forgiving when you’re moving. More on the cable here.

    Generally though, after fiddling for a seal and such, I find it quite comfortable to last me at least 2 hours before feeling the need to take it off. Quite the ways you can go in that time, I feel.

    Sound signature

    Technically, this is a very capable IEM for the price; heck, sometimes I favor this more than my FXT90.

    Soundstage is quite good; can go head-to-head with my FXT90 on most occasion. On fast and complex songs though, it can get a bit congested, the soundstage collapsed a little bit, the imaging becoming a bit smeared. This is where my FXT90 rise up. Otherwise, imaging and soundstage is superb.

    Isolation is above good at the best of times, mediocre at the worst. On a scale of 1 to 10, with 1 being crap isolation and 10 is total silence, I’d place it on 7 for normal noise (conversations), and 4 for loud BG noise (subways, trains, etc.) with music running at approximately 80 dB.

    To my taste, the MA350 works best with songs that employ double bass, bass guitars, kick drums, etc. but not really with artificial bass. The strength of this IEM lies at its subbass without sacrificing other frequency range. The other thing that I like is the generally warm sound. For example it can make a biting, sizzling metal song into a flurry of fast-paced punches of the snare drums, slightly stealing the spotlight from the electric guitar but .

    Getting a bit more in-depth, this IEM is bass-focused with polite treble and clear mids. Mind you though the above paragraphs work better at conveying how it would be like out and about; the following paragraphs are when the environment is quieter.

    The bass impact is strong; it’s a tiny bit flabby but not to the point of terribleness. The texture of it is also another plus point for the bass that works quite well with jazz and some classical like I alluded earlier. Not to forget is the depth and quality of the bass too. If you’re like me and listen to a variety of genre and there’s that one dubstep song that you like (with real subbass), then rest assured the lowest bass can still be felt. The subbass is quite strong and detailed; amazing bass on most songs I’ve listened to. In some instance there can be a slight change to the focus on some songs, I find it amusing and not for the worst. As a result of this bass focus though, the overall sound will be warm. Mind you though that I’m not a basshead in anyway, but this is easily what I love about the MA350.

    Despite all of that, there’s no bleeding into the mids that I can detech. The mids are still clear-sounding and mellow due to the warmth; nothing shouty nor grating at all. Vocals all sound exceptional, esp. for female vocals, and the male vocals are still no slouch. Upper mids seem to be where the midrange shines; snare drums sounds fast and clear, and I can hear almost each beat on fast passages. Surprisingly, they are not recessed in any way, which is amazing I might add.

    And then comes the polite treble. I’d say that it’s not as forward/focused as the bass and I assume it’s on the same level as the mids. Not to say that you will not be able to hear anything in the range though. The treble is still quite detailed and able to deliver a sense of air and soundstage, without losing the brightness of bright songs. No sibilance at all, but this is expected when the treble is polite.

    Overall, it is a bass-focused IEM, but not in any way offensively excessive, with clear mids, detailed yet polite treble with a good enough soundstage and imaging for less complex and busy songs. Good genre width, works absolutely well straight out of my phone without going high on the volume with good isolation to block out the hubbub of a commuter’s life and comfortable to boot. All of that for $40 MSRP with 3 years warranty, I reckon that this is a great buy for anyone that’s looking to get better sound but not wanting to drop lots of cash.

    Pros - Detailed, incredible subbass performance, great build
    Cons - Stock tips lose seal easily with my ears, microphonic cable unless worn over-ear.
    Thanks to RHA for sending me a pair of these to review!

    What we have here is a headphone that I can only describe as incredible. Very impressive

    Accessories - 3 sizes of round silicone tips and soft carrying pouch.

    Build and Design- The MA-350 has a very nice aluminum housing that holds the driver. Simple, yet shows some elegance. Long strain reliefs show increased durability. Cloth-sheathed cord appears very durable. Doesn't appear to be prone to memory effects. With the cable being covered in cloth, microphonics can be quite bothersome if worn down. They become relatively nonexistent with over-ear wear, though. Cable cinch is useful and well built.
    Stock tips don't work too well with my ears. I seem to lose the seal pretty easily no matter what size tip I use. I prefer to use the Sony Hybrid with the MA-350, which is strange, as I don't normally like the Sony Hybrids too much.

    Comfort - Keep in mind that comfort is very subjective. With my ears, the MA-350 is mainly comfortable, but the large housing design allows for quite shallow insertion, and I seem to subconsciously try to push them in deeper than they can go. It's a slight problem that I have. Other than that, the comfort of these is quite good. 

    Isolation is a bit above average for dynamic driver IEMs with large housings. Lack of venting is probably the reason for that.

    Sound - The sound is pure bliss for me.

    Bass - These IEMs deliver some of the best sub-bass response I've ever heard from an IEM, especially in this price range. It's punchy, detailed, and very controlled. Quite a lot of sub-bass too. 
    Mid-bass and upper-bass are neutral when compared to the rest of the spectrum. I wouldn't consider it warm sounding at all, but I don't think I would go as far as to call it cold. 

    Mids - The midrange is a tiny bit recessed to my ears. Definitely not enough to be considered a v-shaped signature, but enough to notice. It's pretty clean sounding overall.

    Highs - I don't know whether to consider the highs or the bass as the main focus of these. The highs on these are very nice. Detailed, bright, sparkly. I love it.

    Soundstage - Slightly above average for a dynamic IEM. Depth is good. Width is average.

    Overall -  The RHA MA-350 is a great contender in the $40 price range. With incredible sub-bass and sparkly highs, these IEMs can really make any kind of music sound great, but I think they work best with electronic music, like DnB, dubstep, and electro house. Build is fantastic, and a 3-year warranty shows that these can be working for you for a long time. 
    Highly recommended.

    A Good and Durable Budget IEM

    Pros - Aluminum housings, Solid Bass, Comfortable
    Cons - Not the best accessory pack,
    First, I’d like to thank the folks at RHA for sending me a pair of the MA-350 to review.
    RHA is a name I’ll admit I’m not immediately familiar with, so when an email fell into my inbox, offering me a chance to review their MA-350 model IEM, I admit I was a bit skeptical. But nonetheless, I accepted the offer and a couple days later the package arrived in my mailbox. So, does this upstart have what it takes to box with the best in the budget class? Read on to find out.
    Packaging and Accessories: Comes in a simple paper/plastic box with three pairs of single flange eartips and a drawstring carrying case.
    Design and Build Quality: Solid metal shells made of machined aluminum feel exceptionally sturdy without being heavy. The cable is well relieved at both ends, features a nice chin slider and a cloth weave covering. Overall, I’m impressed with the tank-like build and RHA backs these up with a rather impressive 3 year warranty, not something you see often.
    Comfort and Isolation: The bell shape surrounding the 10mm dynamic drivers was most comfortable when I wore them over the ear, due to the long strain reliefs pressing lightly against my outer ear when I wore them straight down. Throughout most of my listening sessions I barely noticed they were in my ears, even over fairly long periods of time.
    These isolate well for a dynamic driver IEM but can’t compete with the balanced armature IEMs in my collection in that respect. Microphonics were surprisingly quiet, in spite of the cloth covered cable, which I’ve found exacerbates these noises on a number of IEMs.

    Sound Quality

    Burn in: The RHA MA-350 IEMs were given upwards of 50 hours of burn in time prior to review. No significant changes were heard.
    The low end is…peculiar. I’d hesitate to call them neutral but they’re neither bass light nor heavy so I guess I’m going to have to. The bass boasts impressive depth and very good texture and refinement in a way that will never creep up on the mids or muddy the sound but has the ability to step forward when a song calls for it. The bass is also less punchy than it is textured, with a full weight and body but doesn’t punch as hard as many dynamics I’ve reviewed. Personally, I’d say it has more similarities to balanced armature bass than that of dynamics, which was peculiar at first but is nonetheless great for a wide range of music.
    The midrange is slightly cold in tone as well as linear and smooth. Vocals are nicely defined and everything sounds as it should. The micro detail retrieval is impressive, thanks to a slightly thin note presentation, which again makes me think of balanced armature based IEMs in a positive way. The high end is similarly detailed and airy.
    The most immediately striking aspect of the MA-350 is the clarity and openness of its sound. It surprises with the depth of its soundstage and its ability to image properly, with a good sense of space between instruments and vocals and makes for a coherent and enjoyable presentation.


    Just about every aspect of the RHA MA-350’s sound signature impressed me, especially since they retail for about $40 and sound like they’d cost much more. It’s clear, detailed, engaging and refined to the point that it can box above its price range with ease.
    So, yeah, I recommend the RHA MA-350. It’s quite the impressive performer for $40 as long as you’re into a neutral sound that emphasizes clarity and detail above boosted bass and treble. It seems the budget IEM set has yet another very competent challenger in RHA.

      I agreed with what your review says, this is indeed a good IEM that deserves more attention

      My findings are quite similar to yours, particularly in regards to the bass. I've been waffling about getting my review out, but I agree--definitely not typical of the products in its price range.

    RHA MA-350 Quick Review

    Pros - Drama, Bass, Treble.
    Cons - Dry, Mids
    RHA MA-350 Quick Review
    Thanks to RHA for the sample.
    Brief:  Teeny tiny inverse trumpets.
    Price:  £30
    Specification:  Drivers 10mm Mylar, Frequency range 16-22,000Hz, Impedance 16ohms, Sensitivity 103dB, Rated/max power        3/10mW, Weight 11g, Cable 1.2m Fabric braided, Connections 3.5mm Gold plated
    Accessories:  3 pairs of tips and a little baggie.
    Build Quality:  Premium.  Machined aluminium buds and a weave covered cable sleeve all makes this feel like you’ve spend rather more than you have.  The cable is a little ridged but I cannot deny if feels nice in the hand.  Y splitter and chin strap are nice too.
    Isolation:  For a dynamic really not bad, thankfully it didn’t give me any driver flex problems as is common with sealed dynamics.  Se while it’s not as much as I’d want if going to New Zealand its easily enough for normal sat on a bus type stuff.  As always my warning, it’s also enough to turn you into road kill if you aren’t looking where you’re going too.
    Comfort/Fit:  Given its sealed and its metal with great big looking buds I expected trouble, I didn’t really get any though.  There was a touch of air pressure issues but it was no trouble making these sit right, plus they were happy to be worn up so their metal weight I never noticed at all.  Their outer edge may be big but the taper rapidly so I had no fit trouble at all, I wouldn’t expect anyone too either.
    Aesthetics:  Not what I call exciting but they do look discreet with their black outer.  The inside of them is pretty aluminium but you’ll never actually see that, why no all black or an all silver version?  Still when you look at them in your hand they look nice and premium, the woven cable too looks tre posh.
    Sound:  It’s not trying to be flat so if you want that, look elsewhere.  The sound here is a big and brash V shaped sound.  Big bass that reaches deep and bright crispy edged treble in abundance.  Mids are very dry and airy which is just as well, they need it to stay clear when they are living in that great big V. Vocals don’t stand out but they are always clear and articulate.  The bass is very impressive and I found I rather liked them for film watching, Jurassic Park type rumble and roars were a great deal of fun, just the sort of thing for a long train journey if you ask me.  The highs were a bit over crispy and over dramatic but if you want that in your face drama and excitement it brings to the table then I’m not sure you’ll get that for similar money elsewhere.  It’s a hard thing to do with ballsing it up or spending a ton of cash.  That RHA have gone for something so hard and done a really impressive job is admirable.  Truly tremendously dramatic bass output here.
    Value:  If you want a really V shaped sound you’ll have trouble nearing this for £30.
    Pro’s:   Drama, Bass, Treble.
    Con’s:  Dry, Mids
