RHA MA750 / MA750i Review

RHA MA750
Reviewed December 2014

Details: Flagship in-ear from Scotland-based RHA
MSRP: $119.95 (manufacturer’s page) ; $129.95 for MA750i w/mic & 3-button remote (manufacturer’s page)
Current Price: $120 from amazon.com for MA750; $130 from amazon.com for MA750i
Specs: Driver: Dynamic | Imp: 16Ω | Sens: 100 dB | Freq: 16-22k Hz | Cable: 4.4′ I-plug
Nozzle Size: 4.5mm | Preferred tips: Stock single-flanges
Wear Style: Over-the-ear

Accessories (5/5) – Single-flange (6 pairs in 3 sizes) and double-flange (2 sizes) silicone tips, foam tips (2 pairs), shirt clip, stainless steel eartip caddy, and zippered leather carrying case
Build Quality (5/5) – As with RHA’s lower-end models, the construction is impeccable. The MA750 boasts machined stainless steel housings, metal nozzle filters, and thick, rubbery cables. At the earphone end there is a molded “earhook” section about 4” long. It’s not memory wire, but it’s a lot more comfortable than the earhooks I’ve come across in the past. The cable is thick and tangle-resistant, and all of the hardware is metal, including the 3.5mm I-plug with a long “spring” strain relief. The 3-year warranty is very impressive as well
Isolation (3.5/5) – The housings are narrow at the front, allowing a good insertion depth and good isolation
Microphonics (4.5/5) – The cable carries some noise but microphonics are generally not a problem due to mandatory over-the-ear fitment and the fact that the cord is thick and heavy, and doesn’t move around much
Comfort (4/5) – The earphone housings have a familiar flared shape a-la Dunu Trident and RHA’s lower-end models. The earpieces of the MA750 made of stainless steel, though, so they are a little heavier. The small diameter at the front nonetheless affords a surprisingly comfortable fit considering the weight

Sound (8.9/10) – The previous RHA earphones I’ve tried left me impressed with their bass power and clarity, but the new MA750 is a strong performer all around. Its signature is predicated on enhanced bass, but less so compared to the lower-end models. It has a strong emphasis on sub-bass, and a little less on mid-bass. The bass quantity is not at what I would consider “basshead” level – deep bass presence is good with the MA750 but there’s not too much mid-bass punch compared to some of its competitors. On the other hand it is a lot bassier than the HiFiMan RE-400, which sounds more controlled but appears deficient in subbass in comparison the RHA unit.

The MA750 is warm in tone, but not overly so. It has decent enough treble presence to balance out the bass, though it is certainly is not a neutral earphone. The midrange is rich and full-bodied, with very decent clarity considering the sound signature. Clarity is better than with many other stereotypically “warm” earphones, such as the Sony MH1C and Dunu Trident. The RE-400, on the other hand, is more mid-centric, but still sounds more neutral and is a little clearer through its midrange. The pricier Dunu DN-1000 hybrid, too, is clearer, making the MA750 sound veiled comparison.

The upper midrange of the MA750 is energetic but emphasis diminishes before getting into the regions that typically cause harshness and sibilance. The MA750 is brighter overall compared to the Sony MH1C and Dunu Trident and has a slight tendency to sound “tizzy”, especially at high volumes, thanks to the lower treble emphasis. It isn’t bothersome, however, and I definitely would not call the treble energy excessive. On the other end of the spectrum, the Dunu DN-1000 has treble that is brighter and more revealing of artifacts, making the MA750 sound quite smooth in comparison.

Presentation-wise, the MA750 performs well for the price. Its soundstage is larger than those of the MH1C and Trident, and separation is better as well. The Trident especially sounds more in-the-head and congested in comparison. Aside from the enhanced bass having the ability to throw a slight veil over minute details and take away from its imaging ability, there is not much to complain about with the MA750 here.

Select Comparisons

RHA MA350 ($40)

RHA’s $40 MA350 is one of my favorite budget-friendly sets for enhanced bass, but while the flagship model does command a healthy price premium, it also offers up a significantly more refined sound. The MA350 has strong, domineering bass, but the MA750 manages to sound rich and full-bodied while maintaining lower overall bass quantity and better bass control. It’s more balanced, as well as smoother and more refined. The treble of the MA350 is a little grainy in comparison, and more prone to harshness. The MA750 sounds more natural and enjoys a larger presentation with better depth and separation, making the MA350 appear congested in comparison.

Onkyo IE-HF300 ($129)

The IE-HF300 couldn’t be more different from the RHA MA750 in design, but sonically both earphones tend towards a warm, enhanced-bass sound. The RHA unit boasts bass that is both more extended and more powerful overall. The HF300, meanwhile, has less bass quantity with a focus on mid-bass. This results in mids that are a little more veiled compared to the MA750. The MA750 sounds clearer and more crisp, though it is a little more laid-back at the top end compared to the Onkyos. Both earphones boast above-average soundstages, with the HF300 being a little more open-sounding.

RBH EP1 ($149)

Yet another enhanced-bass, consumer-friendly earphone in the sub-$150 range, the EP1 nonetheless offers a sizable contrast to the MA750. Both earphones have a strong emphasis on bass but the MA750 is a little more powerful here, which gives it a warmer and more full-bodied sound. The RBH earphones place more emphasis on the midrange and sound a little clearer as a result. The MA750, on the other hand, has a thicker midrange presentation and a smoother and more forgiving sound. The RHA also boasts a slightly wider presentation and tonal character that, to me, is more natural overall.

VSonic GR07 Bass Edition ($179)

This earphone’s “Bass Edition” moniker is only true insofar as it is more bass-heavy than the regular GR07. Next to the MA750, however, the GR07BE sounds rather balanced. The RHA unit has more bass and a warmer tonal character while the GR07 is closer to neutral. The bass of the MA750 is boomier and results in more veiling of the midrange. The GR07BE lacks some of the full-bodied character of the RHA, but remains clearer, especially in the midrange. Up top, the MA750 is a little smoother where it counts while the GR07 is more sibilance-prone.

Value (9/10) – The RHA MA750 has a lot going for it – a warm and lush sound, spacious presentation, and good bass presence. No less important is the construction quality, which features stainless steel housings and thick cabling. The earphones are comfortable, too, thanks in large part to the over-the-ear fit and molded earhooks, and isolate surprisingly well. Most impressively, the MA750 is not at all exorbitantly-priced – it’s extremely comfortable just north of $100. Early last year I found myself impressed with the entry-level MA350 and hoped to see more great things from RHA, and this year starts off with another hit from the Scottish manufacturer.

Pros: Extremely solid build quality; 3 year warranty; warm sound with excellent bass presence
Cons: Housings a bit on the heavy side

  1. Hello Joker,

    thanks for the excellent review! Could you compare RHA MA750 with Yamaha EPH-100? I have a pair of Sony MH1C earphones and liked the sound quite a lot. I am considering getting a new pair of IEMs just because I feel like trying something new (and better of course :-) ).

    • The EPH-100 is bassier overall but also has a little more midrange presence to me whereas the MA750 tends to sound a bit more veiled. MA750 is brighter though and has more lower treble energy. Really comes down to what you want – the EPH-100 is a better signature match for the MH1C while the MA750 is a bit more of a contrast.

  2. I feel that a comparison to EPH-100 should have been included in the review itself.

  3. Hi! Thank you for your precious work. The sound signature of these IEM seems similar to that of Klipsch x10i (I’ve just bought that and love them almost completely). Can you give a quick comparison of these two models. Thank you very much, Marco (Italy)

    • In terms of general sound signature they do have a lot of similarities, especially in the bass and midrange. Both have good midrange clarity and enhanced bass with an emphasis on deep bass. The RHA MA750 has a “fuller” bass presentation but the X10 is no slouch, especially for a BA earphone. The biggest difference would be in the upper midrange and treble, where the MA750 has more energy and better extension, respectively. Lack of treble energy was probably my biggest complaint with the X10, but not with the MA750.

      • Thank you. I’m replacing my set of two under 50€ IEM with two 100€ IEM of somewhat different sound signature, and I think the second one (with the Klipsch x10) could be the RE-400!

  4. Very goo review. Could you compare RHA MA750 with UE TF10?

    • Yeah, sure – the MA750 a lot bassier – they both have good bass extension but the MA750 is a lot more impactful. It also has a warmer tone. The TF10 is more neutral in tone and its mids are more in-line with bass. Because of its lesser bass quantity it can appear a touch clearer on bass-heavy songs than the MA750 but most of the time their clarity is similar. They have similar treble energy but the TF10 sounds a bit more refined to me there. Both have good soundstage size but the TF10 images a little better.

  5. Are the RHA’s worth the extra scratch over the Philips Fidelio S2 at a little over a 100 bucks and the JVC HA-FXd80-Z at 79 bucks? I listen to a little bit of everything from rap to heavy metal to classic rock to some EDM music and even country. I’d appreciate help, thanks in advance.

    • Oh and also if it’s not asking too much a short comparison would be great too.

    • Different sound signatures – the FXD80 is good if you like a v-shaped sound with a cooler/brighter tone. The MA750 if you want a slightly v-shaped but overall much bassier and warmer-sounding earphone, and the Fidelio is the most neutral of the three. I did compare the S2 to the MA750 and thought it was more neutral, clearer, and more transparent, but also a little harsher in the treble region. The MA750 is warmer and bassier, and sounds thicker overall.

  6. Joker, you forgot to give the “recommended” badge, like for the DN-1000? :)

    By the way I bought this (based on your recommendation) after the GR07 and I like this more, I think its not perfect, but a really great package for the money. I am happy with my purchase!

    • Haha the DN-1000 got the first badge ever. I didn’t go back and retroactively add it to sets I had reviewed previously, though I might when I have time.

      Glad you’re enjoying these!

      • :)) You are right, sorry!
        I just tried the DUNU (and read the review about the DN-1000) before these and I thought you wrote this review after the DUNU, I see that I was wrong..
        By the way I like these more than the DN-1000, EPH-100, GR07BE (because of the smoother and not weird highs), so I had to buy and try quite many to arrive here, but at least I obtained some knowledge about the topic :)

  7. Joker, please give me advice.
    I can’t decide between RHA MA750 and VSonic GR07 BE.
    I like my TF10, but want more impactful bass and sub-bass, but same or better control and overall sound quality. The treble could be smoother too.

    • For significantly more bass impact and especially depth you’ll want the MA750. However, you’ll be sacrificing a bit of clarity compared to the TF10/GR07. This works in the context of the warmer MA750 signature but something to be aware of nonetheless.

  8. Hey Joker, have you heard the DN 900 yet? If so then how does it compare to the MA750? If not then are you planning to review it? Thanks as always for your reviews.

    • I have, and I don’t find it to be as good as the MA750. Its bass is good (deep, but not too enhanced) but the mids are a little more veiled than I would like and the treble can be unrefined at times. The MA750 is better IMO.
