Review: RHA MA-750 (one of the best sub $200 IEM's around)

Firstly I would like to thank RHA for sending me this sample to review, I will write as honest a review possible. These received over 50hrs of burn-in, no major differences were noted.

Gear Used:
IPod Classic 160gb (rockboxed) > MA-750 (clear bi-flange tips)

Technical specifications:
Driver - Dynamic
Frequency range - 16Hz - 22kHz
Impedance - 16ohms
Sensitivity - 100dB
Cable length - 1.35m

Packaging, Accessories and Build quality:

Packaging is simple, black box with a picture of the IEM's on the front, there is a tab that opens to show you the IEM's and all the tips through a plastic window. The IEM's are securely fixed in a plastic in tray. Underneath this you will find the carry case. Information and specifications can be found on the back of the box, and also on the inside of the front flap. These come with a 3 year warranty.
Accessories included are great, you get a wide array of tips included, and a carry case. Included are 2 pairs of S, M and L single flange silicone tips, 1 pair of S bi-flanges, 1 pair of M bi-flanges and 2 pairs of M foam tips. Very good array and quantity of tips to ensure all will get a good fit.

Build quality is top notch, stainless steel housings feel durable, with a thicker than normal cable, and excellent spring strain relief on the jack. These feel like they will last a long time, all strain reliefs are strong, the y-split and jack are stainless steel too, very well built.

Comfort, Isolation, Driver-Flex and Cable noise:
Comfort is excellent once you find the right tip and insertion depth, I like the small bi-flange tips as it gives me a great deep seal and the monitors sit fairly flush with my ears. The memory wire section is not stiff like most, it is soft rubber and has no wire inside so you cannot form it, but I find this much more comfortable and stronger.

Isolation depends on the tips you use, using the bi-flanges I get good isolation even though they are vented housings. Great for everyday use.

Driver flex is not present luckily.
Cable noise is not a problem as the cable goes behind your ear, but using the chin slider will get rid of any slack and potential cable noise.

Split in to the usual categories

Lows: nice full bodied lows, lots of power and energy but with good control not warming the mids up. The lows have great extension and presence without being overwhelming, I would say that a little less quantity wouldn't hurt but as they are, they fair very well and are fun and pleasurable to listen to. The speed is very good however and they manage to keep up with fast music with ease. Very dynamic and articulate bass with good separation too, kick drums have great body and sound very realistic, bass guitars have perfect decay.

Mids: in quantity they are slightly behind the lows, but are not recessed, they are very natural sounding. These IEM's have a slightly thick sound, but the mids are not affected by this, sounding very clean and detailed. When multiple vocals are recorded you can hear each voice well separated. Vocals have no sibilance or harshness to them, and guitars retain great power and control.

Highs: the highs lack some presence, but what they lack in presence they make up for in control and detail. The highs are very crisp and controlled never becoming splashy, also the highs are well placed within the soundstage. You can EQ the highs up a little with good effect but I rarely use EQ. There is not a lot to say about the highs, they are detailed but don't have enough presence for my tastes, and the sound ends up sounding a little dark.

Soundstage is wider than average, and they give you a good sense of space.
Instrument separation is also above average with a well controlled sound and everything is easily separated.
Imaging is very good also, being very precise and coherent.

Overall a very good IEM for the price, it is definitely one of my favourite sub $200 IEM's, it has a slightly fun but natural sound, add to that great comfort and build quality you have a winner. They are slightly on the darker side of sound, but have enough detail to keep things interesting. I really enjoy this IEM when out and about.

Sound perfection rating: 8/10

  1. Purchased the MA 750i today as replacement of a competitor in-ear headphone (costing twice). I replaced it because of not satisfying sound performance. Well, I saved roughly 100 euros and now I'm listening to the music in a perfect way... Thanks for this review. Paolo

    1. I'm happy you found some in ears you enjoy, and that you ended up saving some money! That's great to hear.

  2. I am looking for a IE buds. How does these compare to se215/se215ltd in noise isolation? If I use comply ear tips, which will give me a better NR in db? If they are about similar, which would you go with?

    1. The SE215 LTD are very good, but I prefer the timbre of the MA-750. Shure have slightly better isolation but the difference is not big. The MA-750 don't have a detachable cable but have a 3 year warranty. The MA-750 is fuller sounding, the SE215 LTD might have a tiny bit more clarity

    2. This comment has been removed by the author.

  3. Thanks, any other recommendations besides these 2 for isoaltion and quality?

  4. How would these compare to the heaven ii as they're in a similar price range?

    1. The RHA are darker, bassier and more fun. The Heaven II is balanced and detailed, faster in attack and decay but lacking a tiny bit in the lowest of lows (bass boost on an amp usually helps a lot, an amp with the Heaven II is also advised)

  5. Hi
    Given that you have reviewed both MA750 and DUNU Dn1000, how do you compare them in different sound categories? which one is a better value for the money they are priced?

    1. They are both quite different IEM's, the MA-750 is lush and warm, and quite thick sounding with excellent fit and build quality.

      The DN-1000 is also more warm but has better clarity and detail retrieval, but it is not as well built (but the build quality is still excellent) and the fit is also not as good.

      For clarity and punch: DN-1000
      For easy non-fatiguing sound: MA-750

    2. Thanks for your reply.
      Then you are meaning that DN1000 has more bass ( or midbass) than MA-750, is that right? What about soundstage and imaging?
      I also have some fear that DN1000 will have some sort of sibilance and sounds harsh (specially in high volumes), considering that it has more treble presence. What's your opinion?
      My old pair of headphones are: klipsch image s4, xiaomi piston 2 and sennheiser momentum over ear, and i'm driving them through Fiio X3.
      Thanks in advance

    3. DN-1000 has more clarity but I would not class it as sibilant. It has more bass impact, but the MA-750 is fuller sounding.

      Soundstage is good on both, the DN-1000 has more space around the instruments, but the MA-750 still has quite a wide soundstage, separation is better on the DN-1000

      I prefer the DN-1000 purely because it is more detailed but not harsh, the MA-750 is more comfortable and fuller sounding. It all depends on your preference.

    4. Thanks for your kind help.
      For the last question I have, what the term "fuller sounding", you mentioned, exactly implies?

  6. fuller sounding is fuller sounding
