RHA MA390 Review

When I look at the RHA MA390 on paper, I see a portable headphone built around a very old-fashioned virtue: staying out of the way. The recorded dimensions are 1.19 x 1.5 x 135 cm, and the listed weight is just 15 grams. That tells me the main appeal is not big housings, heavy hardware, or a software-led feature set. It is pocketability, low bulk, and simple daily use.

First available on 1 Sept. 2017, with model number 201008, the MA390 is not listed as discontinued by the manufacturer. My read is that this is more of an established everyday RHA option than a short-cycle tech gadget. I would approach it with practical expectations rather than expecting a modern smart-headphone platform.

Why the 15-gram figure matters

The number that stands out to me is the 15-gram weight. For a portable headphone, that is not a throwaway detail. Less weight usually means less hassle in a pocket or bag, and it makes more sense for commuting, walking, studying, or keeping a spare set nearby.

I would not buy something like the MA390 because I wanted a large, immersive home-listening setup. I would consider it because I wanted something compact enough to carry without thinking about it. The slim recorded dimensions point in the same direction: this is a convenience-first product category.

What I would not expect from the MA390

The honest limitation is that the recorded facts do not show a guaranteed software-update window. That matters if you are shopping for app-based features, firmware support, or a product that depends on long-term digital maintenance. I would treat the MA390 as a hardware-first headphone, not a connected platform.

• Skip it if you want smart features: if your priority is active processing, app control, or confirmed software support, this is not the spec sheet I would start from.
• Skip it if you want a large headphone feel: the MA390’s recorded size and weight point toward portability, not the physical presence of bigger models.
• Check before ordering: I would confirm the current retailer listing, compatibility details, and what is included in the box, because the recorded facts here are limited.

Who I think should shortlist it

I would shortlist the RHA MA390 for someone who wants a light, compact everyday headphone from RHA and does not need software support to be part of the value. It makes the most sense as a simple daily-carry option: small, light, and easy to keep nearby.

I would skip it if the buying decision depends on advanced features, large-format comfort, or a clearly stated long-term update policy. But if the brief is simply “give me a very light portable headphone without unnecessary complexity,” the MA390’s recorded specs fit that role neatly.
