Closer Examination

The RHA MA750 Wireless sports a neckband design. Meaning, the wire that connects the ear pieces to each other loops through a thick, silicone-covered band that will rest behind your neck. The band itself is extremely comfortable and doesn't feel heavy around the neck. If you're a jogger or a runner, do keep in mind that the neckband will inevitably jump up and down while you perform your favorite activity, which some users could find annoying.


Putting on headphones like these is essentially like putting on a necklace, more so because of the fact that the stainless steel ear pieces of the MA750 Wireless are equipped with strong magnets, which has them firmly snap together and stay that way until you separate them and push them into your ears.


On the other hand, if you want to use the RHA MA750 Wireless for running, you definitely can—not only because of the IPX4 rating (sweat and splash resistance), but also because they fit in and around the ears very securely. The cable around both ear pieces is bent in a way that forces you to loop it behind your ears, which is a clever way to ensure that the ear pieces stay in place regardless of what the listener is doing. Of course, to fully secure the fit, you'll have to spend some time to find the ear tips that work best for your ears. That's exactly why it's so nice to see RHA provide a grand total of ten pairs to play around with. The selection of ear tips will also directly impact the sound quality of the headphones, as well as the amount of sound leaking in and out. While I wouldn't consider these to be predominantly sport headphones, the aforementioned characteristics make them very suitable for users with an active lifestyle.


The thickened part of the left side of the neckband has an NFC logo on it. You know what to do—if your smartphone supports NFC, you can tap it here to establish a wireless (Bluetooth) connection with the headphones. Even though I don't find NFC particularly useful, its logo did make it easier to quickly figure out which side of the neckband needs to go on my left shoulder.


The thickened right side of the neckband contains the USB-C charging port and power button. The power button is also used to switch the headphones into Bluetooth pairing mode for when you want to connect them to your devices for the first time.


Further down the line, on the right side of the neckband, is a small remote control with a metal case, a built-in microphone, and three rubberized buttons. The buttons are somewhat hard to click; loosening them up a bit could be a good idea for future iterations of RHA's wireless headphones. You can probably guess at their purpose—the outer two buttons control the volume, while the middle one has several functions. A single click of the middle button will play or pause the song and answer a phone call. A double click will drop the phone call or switch to the next song, while a triple click takes us back to the previous song. Finally, holding the button activates the microphone and your smartphone's voice assistant (Google Assistant in my case). While some may find it odd that the controls listed above aren't simply placed on the neckband, there's a good reason for that as the remote control brings the microphone closer to the mouth. Having the microphone sitting behind your neck would severely hinder its usability.


The stainless steel speaker driver housings look and feel luxurious and practically indestructible. The nozzles (sound tubes) are perfectly round and make replacing ear tips a breeze. As long as you find a suitable pair of ear tips, the nozzles themselves won't cause any discomfort to your ear canal, and the RHA MA750 Wireless will feel very comfortable.


The replacement ear tips are neatly organized on a metal credit-card-style plate. There are three styles to choose from—the silicone tips come as single bore (small, medium, large) and dual flange (small and large) tips, and there are two pairs of Comply foam ear tips (both medium in size). I'll talk more about the characteristics of different ear tips in the audio performance section of this review.

Battery Life and Wireless Range

RHA claims the MA750 Wireless has 12 hours of battery life, which isn't far off from what I was getting during my testing. I was regularly able to hit around 10 to 11 hours of uninterrupted use with high listening volume and frequent microphone use (phone calls, Google Assistant). Meaning, even if you're a heavy user, these will get you through your day with ease. The headphones have a built-in power-saving feature that turns them off completely after 20 minutes of inactivity. A female voice will inform you about the remaining battery percentage every time the headphones establish a connection with the phone. Also, you'll be able to check on the battery at any time in the Bluetooth settings of your phone, as the headphones continuously report it.

The wireless range is what you'd expect from a good Bluetooth 4.1 device—you're welcome to freely move in a 10-meter radius from your sound source. As long as there are no thick walls between the headphones and the source, you should be all set. I didn't have any issues with connection drops or sound distortion. Two different devices can simultaneously be connected to the headphones.

Microphone Performance

As I already mentioned, the microphone is built into the remote control, and the remote itself positions itself just below your right cheek when using the headphones. Although the microphone can struggle in windy and exceptionally noisy conditions, I found it very usable for taking phone calls and talking with Google Assistant. My voice did sound quite tinny and telephonic, but as long as the message gets across, that's as much as one can expect from a microphone of this sort.
