Betron Pro-X7 review
Throughwork
Betron sell direct from source to online retailers. Some of their models are top‐sellers. This is their most expensive earphone, and plainly has a place.

Build
Through‐built by the cheapest way possible, with… interesting… thinking here and there. The cable is braid‐covered, but no thicker than any other and stiff so it is near‐springy. It doesn’t tangle much but it does hoop. The plug and Y‐split are some fly‐weight metal, anything else that gleams is plastic. The earphone housings are tablet‐shaped and go in medium depth. They hold only passably because the housings are light, but the large size and stiff wire can lever them out. The Pro‐X7s feel like they will break if you trod on them, but are a good assembly. The big housings are outstandingly easy to push in ears, but stick out a lot. The switch is all plastic, with a strong, long‐throw action. I could understand a claim the Pro‐X7 look distinctive—they do— but shiney photos in use look to me like parts that fell out of a model kit.
Sound
Good volume. Horns jut out. Only reasonable volume range. Attack/decay is dull. Timing is reasonable. Dull round lower/mid strings. And fizzy round female voice and low‐high strings. The Pro‐X7s blur when there is a lot happening, though not muddled. Hiss from outstanding range of highband. Lowband seems permanently recessed. There’s an overall tinniness (in plastic cases?) which is open but not accurate. And the lowband, when it sounds, booms. Detail from the highband range, but unconvincing from the driver. Detail missing on lowbands. Color missing everywhere, though better on lowband. Scale is wide, but poor positioning.
I tries swapping for the foam tips, which made the lowband boom like pillows, the topband tinnier, and showed the lowband slow behind the highband. I tried an equalisation like demolished skyscrapers, and the none of the features disappeared, but the Pro‐X7s did become passably engaging. These are a good vocal earphone, if not informative. Which makes them reasonable also for solo instruments then, as features intrude, it’s downhill from there.

Assess
Betron are a top‐selling earphone manufacturer, so it is no surprise they would enter a model in the bracket over the bulk of their sales. The springy wire resists tangling but is noisy also. The sound has outstanding frequency range, and in the highband is even, which makes the Pros‐X7s good for podcasts and phonecalls. But muddle, echo, recessed lowband, and a lack of detail and timing overpower those virtues.
The dual drivers deliver highband notes over an outstanding range, but the trick there is to make the cones work together—this earphone seems to favour hiding it’s lowband. And the housing echoes. Reviews say Pro‐X7s have clear sound—correct about extended highband—but that they can break within weeks. With care for presentation and accessories, it seems the Pro‐X7 wants to be all things people want. And a bit of lowband boom and clear highband are the first items people latch into. But to me the Pro‐X7s are like listening to a quality sound system through a tin can.
