Finding a good pair of wireless earphones is like picking out your favorite scotch. Do you prefer single malt or single grain? Well, the RHA’s MA750 Wireless are like a blended malt scotch. They’re a rare middle ground for those of us who want to exercise with our primary pick without compromise. The aptX and AAC compatibility pairs well with a smart, Aerophonic™ design and and well-tuned drivers, providing us with an impressive package.

But does said package outshine the competition?

Who’s buying?

  1. The high quality build materials and more neutral sound characteristics of the RHA MA750 Wireless appeal to those looking for a high-end portable sound with appearances to match. If James Bond wore wireless earphones, I’d like to think that he’d rock these, even at the risk of ruining the look of his suit.
  2. The RHA MA750 Wireless are also ideal for frequent commuters or travelers.

What’s Inside

RHA includes a stainless steel plate to hold silicone tradition, flanged, and memory foam ear tips.

The RHA MA750 Wireless are a direct transplant of its wired MA750 predecessor. A stainless steel plate with precise cutouts contains a plethora of spare ear tips, two pairs of which are Comply memory foam. Aside from that, RHA provides users with a strong yet pliable synthetic, zippered carrying case

Build & Design

303F grade stainless steel maintains the durable integrity of the RHA MA750 Wireless.

In typical RHA fashion, the MA750 Wireless are constructed from 303F stainless steel—a big plus for durability. The earphones are also IPX4 certified, meaning that they can take a sweat bath and come out no worse for wear. Like the wired iteration, an oxygen-free copper cable is encased in a tangle-preventative coating.

The included 3-year warranty makes these a long term investment.

Each circular housing is magnetized, enabling users to connect the earbuds when inactive. Ear hooks, however, make connecting them awkward at best. On a positive note, the design effectively mitigates microphonics (the traveling of sound from the cable to the ears).

Moving up, the mic and remote combo is constructed from the same stainless steel as the chassis. Though the buttons are mushy, depressing the center button for a few seconds grants access to Siri or Google Assistant. While RHA retain the bad, they at least kept with the great mic quality. My voice came through clearly, and the mic was able to combat some ambient noise.

Connectivity

The in-line mic and remote is on the right side of the RHA MA750 Wirless earphones. Though the mic quality is great, the buttons are mushy and hard to differentiate.

Maintaining a connection is a given, as the MA750 Wireless never stutter or randomly disconnect. Even going up a flight of 20 stairs and over 50 feet from my phone, the earphones were able to relay sound reliably without interruption.

Flanking each side, a rotund mass holds the battery. On the left side is the NFC logo for quick device pairing, while the right side contains a USB C charging port, a white LED indicator, and a power button. Compatible with aptX and AAC, the RHA MA750 Wireless stream video well, so feel free to watch all the Bojack Horseman you want without uncomfortable lag times.

Battery

The MA750 Wireless charge via USB C.

At 33%-50% volume I was able to consistently hit a timed 11 hours of playback time (1 hour less than the listed 12 hours). That said, if you pump up the volume, you may fall closer to 10 hours of listening time. Yes, the inconsistency is suspect, but 10+ hours is more than enough to meet average listener demands.

Sound Quality

Accurate mids and highs make the slightly lacking bass easy to forgive with the RHA MA750 Wireless.

Though other reviewers have noted that the RHA MA750 Wireless lack bass, this is a relative observation. Bass response isn’t overblown, meaning that — compared to other consumer products — it seems weak. Quite the contrary. The bass is given a solid presence but — to be fair — one that is superseded by the mids and highs.

Unless ill-fitting ear tips are worn, the MA750 Wireless can give you the impression that the music is happening directly inside your skull. Initially, I used ear tips that were slightly too small and was a bit disappointed with the sound. After switching to the provided Comply memory foam tips, the noise isolation is much more effective. Something that could be improved is the clarity. Regardless of silicone or foam ear tips, audio sounds a little muffled.

Lows

Bass is responsive and only occasionally blends itself into the mids. In Buttercup by Hippo Campus, the bridge is carried by a bass solo and eventual drum beat. Though lows aren’t an exciting aspect of the sound signature, it’s important to do correctly, as it has some pretty significant consequences for the rest of your music. Keeping a light hand on bass emphasis keeps mids and highs easy to hear without bumping up the volume.

(If a proper fit isn’t achieved though, the bass degrades quickly. When using the ear tips that were too small, the low end seemed nonexistent.)

Mids

RHA’s website provides a frequency response graph of the MA750 Wireless. Young adults typically hear sounds ranging from 20Hz to 20kHz. This shrinks as we age.

As you may expect, the MA750 Wireless really shine with their reproduction of mids and highs. _Painting Roses (Acoustic)_ by Dresses showcases the sound engineering. Introductory picking sets the tone of the song and the MA750 Wireless relay each note with such attention that I was left wishing each one would linger just a bit longer, so I could fully appreciate it.

Timothy Heller and Jared Maldonado’s harmonies are full of yearning. In the pre-chorus, Heller’s tender harmony perfectly complements Maldonado’s melodic timbre. Neither part is paid more attention by RHA’s tuned signature, making “Painting Roses (Acoustic)” a fantastic song to test the earphones with.

Highs

Wanna really put the RHA MA750 Wireless through the ringer? Play “The Watcher” as performed by Chris Thile and Brad Mehldau. Thile knows how to make the mandolin cool (and how to compose songs that test treble). RHA, yet again, receives high marks regarding the highs. Nimble strumming and finger picking is gorgeously replicated. From 1:07  through 1:16, Thile rapidly strums the mandolin and it sounds extremely well-emphasized.

The bass is given a solid presence but one that is superseded by the mids and highs.

RHA clearly focused on the lively reproduction of the mids and highs. Though, it’s not a complete neutral facsimile as highs become grating after a while. For instance, Franki Valli’s famous falsetto is a bit overwhelming in “Sherry.” Then again, that could just be the nature of Valli’s vocals; best in controlled doses.

Conclusion

The flexible neckband is easy to forget about but is hard to exercise with.

Yes, the RHA MA750 Wireless are expensive, especially when you compare them to more affordable, Bluetooth competitors like the aforementioned Under Armour/JBL Sport Flex earphones ($129.95). But for the $25-odd price bump, you get aptX compatibility, a clear microphone, and more neutral sound signature, while retaining a sweat-resistant IPX4 certification. Whether you’re transient or settled, RHA has constructed a pair of earphones that will fit your ears and  your lifestyle. If you’ve ever found yourself wishing that Glenlivet made a pair of wireless earphones, the RHA MA750 Wireless are the pick of your aficionado dreams.
