RHA MA350 Review

RHA MA-350
Added Jan 2013

Details: First in-ear earphone from Scotland-based Reid & Heath Audio
MSRP: $39.95 (manufacturer’s page)
Current Price: $40 from
Specs: Driver: Dynamic | Imp: 16Ω | Sens: 103 dB | Freq: 16-22k Hz | Cable: 3.9′ I-plug
Nozzle Size: 4.5mm | Preferred tips: Stock single-flanges, Sony Hybrid
Wear Style: Straight down or over-the-ear 

Accessories (2.5/5) – Single-flange silicone tips (3 sizes) and drawstring carrying pouch
Build Quality (4.5/5) – The MA350 boasts solid-feeling machined aluminum housings, metal nozzle filters, and fabric cables with flexible strain reliefs. The cable is a little tangle-prone but the overall feel is one of a higher-end product. The 3-year warranty is very impressive as well
Isolation (3.5/5) – The housings are narrow at the front, allowing relatively deep insertion with good isolation
Microphonics (3.5/5) – Moderate in the cloth-sheathed cable; can be greatly reduced with over-the-ear wear
Comfort (4/5) – The earphone housings have a familiar flared shape a-la Dunu Trident but are compact and light. The small diameter at the front affords a comfortable, unobtrusive fit

Sound (6.8/10) – The MA350 pursues a consumer-friendly sound and delivers on its promise of “a deep, full bass response” in spades, pumping out plenty of powerful sub-bass. It delivers more low bass than either the Brainwavz M5 or Dunu Trident, two solid and bass-heavy sub-$50 in-ears. Though the sub-bass is not very informative, the low end of the MA350 genuinely impresses with its depth and rumble. The response stays strong well into the mid-bass region, resulting in a warm—but not overly so—tone.

The powerful bass of the MA350 makes the mids sound slightly overshadowed and at times a touch muddy. This is far from uncommon for bass-heavy entry-level earphones – there are a few that manage better overall clarity (e.g. VSonic GR02 BE) and many more that can’t compete with the MA350. Note thickness is good and the overall sound is rich and full.

The treble is in balance with the midrange and generally smooth. At reasonable volumes the top end is very inoffensive. The MA350 is smoother overall than the popular VSonic GR02 BE and doesn’t introduce sibilance to a track. A little grain can become apparent at higher volumes—the Dunu Trident behaves better here even though it is not as crisp and extended as the MA350. Top-end roll-off is present, but gradual. No surprises for an entry-level set.

In terms of presentation, the MA350 is again par for the course. It is not the most spacious earphone and, like most budget sets, generally has an intimate, in-the-head presentation. It can get a touch congested but is more than acceptable for the asking price—better, for example, than the more closed-in sounding Dunu Trident.

THL Recommended Badge 2014Value (9/10) – RHA’s first in-ear earphone is a solid entry-level offering. There is quite a lot to like here but ultimately the RHA MA350 stands out in two ways – excellent build quality and deep, subwoofer-like bass. This is definitely the one earphone to show those claiming that in-ears can’t deliver adequate bass across the spectrum and, hopefully, is just the first of many in-ear products from RHA.

Pros: Solid build quality; 3 year warranty; powerful subbass
Cons: Cable noise can be bothersome unless worn cord-up

    typically. With OpenSiteExplorer you can check existing links, heir domain and keywords information. Needless to say, I’m
    still awaiting a post.

  2. I like the MA350 but I don’t have a CX275 or XB50AP so I can’t compare them. The earpods sound very different, they don’t have the deep and enhanced bass of the MA350 and instead have more focus on the midrange and brighter sound.

  3. Woah, speedy answer there! And straight to the point, as always.

    Thanks alot joker, i’ll get the trident then.

  4. For warm and smooth I’d still go trident over the MA350. Those two terms simply describe its sound better – it has more balanced bass (with a little less midrange recession) and smoother, more refined treble.

  5. Hi joker!
    I’m looking for a cheaper IEM to use when i don’t want to risk my more expensive sets, and as a back up pair to have around. As i’m looking for a warm and smoot sounding IEM, i’ve been considering the dunu trident for quite some time. But now i’ve stumbled on this review, and seen that you put the ma350 against the trident more than once.
    So, considered that i’m looking for a warm and smoot IEM, but still with present, clear mids and higs not too recessed, would you recommend the rha or the dunu?

    Thanks in advance, and keep up the god work!

  6. All three are very solid earphones and will do fine across a variety of genres. Personal listening preferences matter more at this level – if you want heavier bass, for instance, you probably want the MA350 whereas if clarity is your priority the SHE3590 is the one to get. I tend to like the Piston 2 best of the three – it’s sort of a compromise in balance, but with a very pleasant sound tuning and nice soundstage.

  7. Hi ijoker/avg joe..
    I like your website, very informative. I am confused among thee Imes i.e philips she3590, piston 2 and rha ma350. I usually listen pop, country and rnb music.

  8. Glad you like the MA350 and sorry the S1 didn’t work out. I wouldn’t have recommended it for bicycle use – too much surface area perpendicular to your movement. The MA350 is still a nice earphone, maybe not as impressive as the S1, but also less expensive. Enjoy!

  9. Hey, thought you might be interested in feedback in your recommendations.
    During the week, the S1 arrived, and here’s my impressions
    – top notch build quality, no contest about the sound quality. They sound much “richer” than the backup headphones I use, you can discern more instruments and layers, very nice.
    – on the downside, rather large earbuds, flat cable is much more annoying spaghetti than I thought it would, overall these don’t fit as easily in my pocket as others! the biggest problem is the wearing/fit though, I don’t seem to get a proper fit with either of the tips, well, wearing them cable-down is always gonna make them stick out a bit and I did get “closure” on the ear, but (I guess) thanks to their angled design they catch a lot of wind noise on the bike, which is absolutely distracting for me. my non-angled experience never had this problem.

    so I got the RHA MA350 off amazon today instead, as they appear to have far smaller earbud units and your review also seemed really good. Now while there’s somewhat of a discernible difference in quality to the S1 even for a newbie like me, they still sound worlds better than my bundled backup units (samsung included in galaxy phones, duh), absolutely sufficient for my needs. and physically they fit so good, don’t stick out, and end up flat so that I could even sleep with these on! they cost a little less too, so I’m very satisfied now. wouldn’t have considered the 350s without your review, so thanks for that!

    Now how to sell those S1s.. shipping back to hongkong is too expensive 😉

  10. Unfortunately the MA600 is more bloated than both the MA350 and MA750 so not really worth recommending.

    Unless you have very large ears it should be possible to wear the S1 cable down – kind of like you would the Klipsch S4. They aren’t as tiny as the Klipsch units, but they’re smaller than the dual-driver NarMoo.

    Thanks for your support!

  11. Awesome info, thanks!
    I was under the impression the MA60 would be a sweet-spot between the 350s and th 700s, which you praised in your buyers guide.
    The S1 seem really nice, I just ordered some off mp4nation. I am a little unsure how they would be worn down the ear, as I really don’t like the OTE style (or do flat cables help? Never had those). Other reviews point out they cannot be worn down-style, but I’ll trust your word on it – since from all the other descriptions, they sound exactly like what I’d need, enforced build quality and the like. But with the angled design, won’t they stick out awkwardly out the ears if I wear them down the ear, ie in reverse angle? The similar sounding Narmoo S1 are not cheaper when you include shipping, (and ship really slow as well) and may have issues at the cable with sweat (I use headphones for running and outdoor exercise a LOT), so I’m not sure they would actually be competition for the Brainwavz.
    used your referal link and will follow up on that support page. Thanks so much!

  12. I can’t say much for the real-world durability of the MA350 but I haven’t had any issues with mine. That said, if you use them the way you described (no carrying case, daily use, etc) then you’ll probably have to rely on the warranty to keep them going. Very rare to see earphones actually designed for that type of use.

    The MA600 is not something I would recommend due to mediocre overall performance for the price, and if you’re a basshead I would stay away from the E10 and GR06. Except for the old GR02 BE, VSonic doesn’t really make basshead earphones.

    As far as I know NarMoo does ship internationally from their website, but if mp4nation is an option (you can definitely get global warranty on their merchandise), I would consider the Brainwavz S1 as well. I thought it sounded like an improved Klipsch S4: . It’s $60, so well within your budget. Both the NarMoo and the Brainwavz S1 are better than the MA350 and Dunu Detonator in my opinion.

    P.S. you definitely can buy us a beer – thanks for asking! Or you can just to use our links when you buy something from, mp4nation, or certain other retailers. You can find out more here: .

  13. Hey Joker,
    I’ve spent the day googling and searching and reading reviews, at one point I always end up on head-fi and subsequently your reviews, now this site, so, before I ask anything, big respect for the work and thanks for all the info and guidance you provide.

    Now I’ve read your buyers’ guide and many other reviews, I am a little overwhelmed by the selection and, for added difficulty, I live in Germany and some of your advised models arent available over here (NarMoo S1, for example). I can use ebay,, another german search engine, and if I want to have warranty.

    I’ve googled with the requirements that I’m a basshead, I don’t want to spend more than 60€ if possible, rather a little less. My Brainwavz m5 broke down the other day, I really liked their sound, but my only experience is Klipsch S4 (mk1) and MEelec ccp51 (these bass-bullets or something, which I really didnt find comfortable at all, too long housing). The Klipsch were good bass but a little “not clear” in highs/mids, from what I recall, and right now the M5 were my go-to model.

    Here’s the thing, I abuse my headphones, and please don’t judge me for it. I toss them in my front pants bag, I don’t use carrying cases, I wrap them around my sansa clip+, I have them on basically every day on the bike, or running, or the subway. And I don’t do over-the-ear-wearing, I just don’t like that feeling. :/ So I was excited by the reviews saying RHA 350 have superior build quality and warranty, but on many users said theirs broke within 2 months or 3.
    So build quality and warranty is an issue.

    So what I found, what’s available in Gemany, etc., is this selection – and what’s been recommended for more or less some or all parts of my requirements:
    soundmagic e10 42€
    RHA MA-600i 70€, MA-600 60€ (Maximum budget!)
    RHA MA-350 35€, but too much cable noise?? Build quality issues?
    RHA build issues? many complaints, broke units
    VRsonic GR06 55€ ebay, slow shipping (possibly warranty issues)
    Audio-Technica ATH-CKX5 36-47 depending on microphone
    Audio-Technica ATH-CKX9IS for 80€ (only if they are some sort of black magic deluxe IEMs, otherwise out of budget)
    dunu detonator 45$ (mp4nation)

    I know it’s a lot to ask and a long text but if you have any advice I’d be very grateful – which of these could be my golden ticket? or is there any model I’m absolutely missing out on? The JVC in your buyers’ guide are hideous, no offense. 😉
    If there’s a paypal donate button somewhere, please provide a link, I’ll send a beer or two your way!


  14. These are budget, enhanced-bass earphones, no point in talking about micro detail with them. The M6 has a wider soundstage.

  15. Hi joker.
    Comparing the rha 350 to the meelec m6, which one do you think is better in delivering micro detail and spaciousness of sound?
