HMX Xinhai vs Aperol vs Orange Boi: Linear Switch Guide

Category: Comparisons
HMX Xinhai, HMX Aperol, and Keygeek Orange Boi are all factory-lubed linears, but they target different sound signatures. Here is how to pick the right one for your build.
Quick answer
Pick the HMX Xinhai if you want a softer, less sharp top-out sound. Pick the HMX Aperol if you want the loudest, most aggressive clack. Pick the Keygeek Orange Boi if you want a clean, clacky bottom-out from a nylon and fiberglass housing. All three are factory-lubed linears, so the choice comes down to sound, not lubrication.
Sound signature: what each switch is actually going for
The HMX Aperol is built around a POM stem and a P7 bottom housing, and P7 is a nylon blend made of PA66 with 50% fiberglass. That combination is why the Aperol is one of the clackiest switches you can buy. The HMX Xinhai goes the other direction: its top housing uses PA12 instead of the more common PA66 or PA2, which makes the top-out sound less sharp and less pronounced. The Keygeek Orange Boi sits between them with an N1 nylon bottom housing that contains 10% fiberglass, giving a clacky and clean bottom-out, plus an M4 strengthened POM stem that reinforces that solid sound.
Materials and what they change at the desk
Material choice is the main reason these three switches do not sound alike. Aperol's 50% fiberglass P7 housing produces a hard, high-pitched clack that carries in a quiet room. Xinhai's PA12 top housing softens the top-out, so the switch sounds rounder and less fatiguing over long sessions. Orange Boi's 10% fiberglass N1 housing is a middle ground: clacky, but not as extreme as the Aperol. The BSUN Snow Diane is another reference point in this group, using an LY stem, POM top housing, and LY bottom housing for a deep clacky sound with a newer top housing mold that BSUN says improves stem stability and reduces wobble.
Factory lube and what it means for your build
All three switches ship factory lubed, so you can install them straight out of the box without a lubing session. That matters if you are building your first custom board or if you would rather spend your time on stabilizers and case foam. The trade-off is that factory lube is applied consistently by machine, not tuned to your taste. If you want a specific feel, you can still add a light hand-lube later, but you do not have to. Note that HMX lists the Xinhai with a Type option and the Orange Boi with Spring Weights options; the Aperol and Snow Diane have no option types supplied, so check the product page if you need a specific weight.
How to choose without overthinking it
Start with the room and the board. If you type near other people or record audio, the Xinhai's softer top-out is the safer pick. If you want a loud, clacky board for a solo desk, the Aperol delivers that more than the other two. If you want clack with a bit more restraint, the Orange Boi is the balanced option. If stem wobble is your main concern, the Snow Diane is worth a look because of its newer top housing mold. Buy ten of one switch first, test it in your board, then commit to a full set.
Trade-offs at a glance
- HMX Aperol: loudest clack: POM stem and 50% fiberglass P7 housing produce a hard, high-pitched clack that is very present in the room. Choose it for a solo desk where volume is not a problem.
- HMX Xinhai: softer top-out: PA12 top housing reduces the sharpness of the top-out sound compared with typical HMX housings. Choose it if you share a room, record, or prefer a rounder sound.
- Keygeek Orange Boi: balanced clack: N1 nylon bottom housing with 10% fiberglass and a strengthened POM stem give a clean, clacky bottom-out without the Aperol's intensity. Choose it if you want clack but still want some restraint.
- BSUN Snow Diane: stability first: A newer top housing mold aims to reduce stem wobble, while LY and POM materials deliver a deep clacky sound. Choose it if wobble is your main complaint with other linears.
Product facts
- KEYGEEK Orange Boi Linear Switch Factory Lubed (10PCS): The Orange Boi uses an N1 nylon bottom housing with 10% fiberglass and an M4 strengthened POM stem, which the catalog says creates a solid and clacky sound signature. This gives you a clacky bottom-out without the extreme brightness of a high-fiberglass housing, making it a good middle-ground linear.
- HMX Xinhai Linear Switch Factory Lubed Edition (10PCS): The Xinhai uses a PA12 top housing, a softer material than the more common PA66 or PA2, and the catalog states this results in a less sharp and less pronounced top-out sound. If you want a linear that is easier on the ears in shared spaces or on recordings, the Xinhai's top-out is the reason to choose it.
- HMX Aperol Linear Switch Factory Lubed (10PCS): The Aperol pairs a POM stem with a P7 bottom housing, which HMX describes as PA66 with 50% fiberglass, and the catalog calls it one of the clackiest switches you will ever see. This is the pick for a loud, high-pitched clack, but it is also the least subtle option in this group.
- BSUN Snow Diane Linear Switch Factory Lubed (10PCS): The Snow Diane uses an LY stem, POM top housing, and LY bottom housing for a deep clacky sound, and BSUN's newest top housing mold is designed to improve stem stability and reduce stem wobble. If wobble bothers you more than pitch, this is the switch to test alongside the HMX options.
Which one should you buy?
Best for
