RHA MA750 Wireless Review: Hi-Fi Sans Cables

RHA is a U.K based company that specializes in building steel-clad, high-fidelity, earphones. Their well-developed lineup has been inhabited by solely cabled earphones, at least till now. RHA’s first wireless earphone,the MA750 Wireless, is blazing the way to RHA’s cable-free future. But is the MA750 Wireless actually worth buying?

You can find the MA750 Wireless for sale here, for $170, on RHA’s official website.

About My Preferences: Heads up, I’m a person! As such, these words are my opinion, and they are tinged by my personal preferences. While I try to mitigate this as much as possible during my review process, I’d be lying if I said my biases are completely erased. So for you, my readers, keep this in mind:

  • My ideal sound signature would be an extended sub-bass with a leveled, but textured, mid-bass.
  • I have a mild treble sensitivity.

Sound Signature
Sonic Overview:

The MA750 Wireless’ sound signature is V-shaped: a mildly recessed midrange, 2–4dB boosted low-end with a mid-bass hump, mild warmth, and a slowly increasing treble. Both extremes of the sonic spectrum are well extended.

Treble: Songs used: In One Ear, Midnight City, Outlands, Satisfy, Little One, I Will Follow

The MA750’s treble is both well extended and resolving. In fact, it’s resolving to a degree I seldom hear on Bluetooth IEMs. Bot attack and decay speeds are quite healthy and are on the upper-end of speed for dynamic drivers. As such, the MA750 Wireless’s treble sounds natural, but quick and precise as well.

High-hats and cymbals sound distinct in even my busiest songs, and they rarely lose tonal definition. String instrumentation sounds sweet and ethereal, with a tonal quality that is rare in this price bracket of Bluetooth IEMs.

Sibilance is non-existent in the MA750 Wireless’ treble. Satisfy was a breeze to listen to.

Midrange: Songs used: Flagpole Sitta, Jacked Up, I Am The Highway, Dreams, Too Close, Little Black Submarines

The MA750’s midrange is recessed, but not so much that any given part of it gets washed out by the other parts of the sound signature. It’s quite linear too, with only a very small rise towards to bottom of the lower mids and a spike right near the 1–2KHz region to add some clarity and presence to the vocals.

Instrumentation is detailed and well toned, taking on a very natural timbre. Guitars, drums, synths, and pretty much anything else blend seamlessly together. Separation and direction cues are strong compared to other Bluetooth devices in this price range.

Vocal tonality is natural and effortless. Intelligibility is above average. The MA750 Wireless prefers male vocals to female vocals, but weights both well.

Bass: Songs used: Moth, Gold Dust, In For The Kill (Skream Remix), War Pigs (Celldweller Remix)

Lower register response on the MA750 Wireless is good, and will definitely get the job done if you are a casual fan of electronic music. While it isn’t particularly aggressive in presence, it is tight and well-controlled. The sub-bass and mid-bass have an okay level of synergy, but the sub-bass feels lacking inasmuch as the MA750 doesn’t output much rumble. As such you can get rumble in bass-heavy songs, just not at low volumes or in subtle instrumentation.

I’ve never heard the bass overwhelm the midrange, and as such, you can expect a high level of clarity during bass drops or other bass-intensive parts of a song. The MA750 Wireless managed to maintain clarity throughout almost all of War Pigs, something I’ve not yet experienced through a Bluetooth IEM.

Packaging / Unboxing

Construction Quality

Part of the name RHA made for itself was derived from its products’ robust engineering. From spring-loaded headphone jacks to stainless-steel Y-splitters, they’re known to go all-in when building their earphones. But that’s why I’m so puzzled with some of the choices made by the engineering team with the MA750 Wireless. For example, the connecting wire that runs from each end of the neck-cable to the driver housing is quite thin and devoid of stress relief. As such its really easy to pull it at sharp angles during normal daily use; a real problem for people who use their devices roughly.

But that strangeness aside, the rest of the MA750 Wireless is actually quite well built. The driver housings are made from finely-machined stainless steel. Emerging from the housings is a plastic stress-relief structure that protects the ear hook-shaped cable jutting from it.

Sitting along the cable is the inline remote. It is identical to the ones that they build into the cables of the standard MA750i and T10/20. It works on both Android and iOS devices and supports pause/play functionality as well as increase/decrease volume, and support for launching both digital assistants like Siri, Cortana, Google Assistant, and Bixby. As a result of digital assistants taking up the “long press” button gesture on the remote, the power button had to be relocated to the neckband.

The neck-resting part of the cable is fairly thick and has the same texture as their IEM cables have. It is flat on the inner face, making it rest far more easily on your neck and preventing it from moving around a whole lot (by inducing more friction).


I find the MA750 Wireless to be very comfortable. While its weight isn’t ideal for trail-running, I find it to have good ergonomics for biking and jogging. And if that’s not your thing, I was still comfortable wearing it at work for several hours at a time. The shell itself is fairly light and not too large, so assuming you don’t have an overly-long neck there shouldn’t be any overt forces pulling them down. And when you’re done using them, or just need to temporarily remove them to talk with someone, simply letting them hang near each other engages the magnets built into the driver housings, making them stick together with the perfect amount of firmness.

Connection and Battery Life

The engineers at RHA placed the MA750’s antenna pretty well since I have no drops or stuttering with it when paired to either my AP60 or U11 (aside from some small stutters that occur when I initially connect it; a symptom that I get with every Bluetooth device I use with those sources). I could put my phone in my pocket, rear pocket, and even Camel Bak while biking and not suffer from a poor connection.

Furthermore, I’ve been able to make great use of the NFC pairing built into it. Since I like to switch sources so often, I find it really helpful to not have to go through the full pairing process every time.

I’ve consistently gotten outstanding battery life from the MA750 Wireless, matching RHA’s claims almost exactly (12 hours). My average is 11.83 hours per charge.


As per usual, RHA stocked the MA750 Wireless with a very good set of accessories. Inside the box you’ll find:

  • 5x pairs of silicone eartips
  • 2x pairs of dual-flange eartips
  • 2x pairs of foam eartips
  • 1x sport-mesh carrying pouch
  • 1x USB-C charging cable
  • 1x cable organizer
I like the carrying pouch. It’s light and easy to stuff somewhere while I’m using the MA750 Wireless. The only downside is that I haven’t quite figured out how to cleanly store the complex shape of the MA750 Wireless inside it due to the pouch’s relatively small size.

The eartips are all high-quality, and I found comfort and good isolation with both the silicone and foam eartips.

The MA750 Wireless is a new benchmark for wireless-audio quality for me. Combined with its (nearly) all-around good construction, stylish appearance, good connectivity, long battery life, and comprehensive three-year warranty, I can’t fault anyone for going with it, even at its $170 price point. So if you’re looking for some of the best audio you can get from a Bluetooth IEM under $200, definitely consider the MA750 Wireless; you won’t be disappointed.

As always, happy listening!

When is this actually going to be available to buy?
Hi, is MA750 wireless will be universal where the mic and remote will connect across most smartphone platforms - Windows 10 mobile, iOS or Android? I noticed RHA only focusing on iOS like T20i. Please focus on Windows phones and androids as well.
