The F9 is one open design, built in Shenzhen factories and sold under dozens of names. AMOI is the label most often attached to it; Volt Plus Tech, MDNS, Huiye, Harigal and BSWLMDD put their names on the same touch buds and LED case.
Fresh as of September 2026No AMOI-branded F9 is on sale in the US right now. The same design ships from BSWLMDD, DCBCODGAL, Volt Plus Tech, MDNS, Huiye, Harigal and a dozen smaller labels. JBL, Samsung and LG make no earbud called F9.
Nobody owns the F9. It is a stock design made in the Shenzhen electronics belt: the same round touch buds, the same LED-readout case, the same Bluetooth chips, sold to any brand that wants a logo on the lid.
The factory names show up in the fine print. MDNS's BTH-F9-5 comes from Shenzhen VISION Electronics, AODE's F-9 from Shenzhen Aoolif Technology, and the DB LLC F9-5C names a JL (JieLi) Bluetooth 5.0 chip, one of the chip families these budget buds are built on.
So what separates one label from another? Not the shell. The parts inside and the promise behind the box do.
| Label | Stated warranty |
|---|---|
| Volt Plus Tech | 1 year, manufacturer's limited |
| DCBCODGAL | 1 year |
| VIVIDUS | 1 month |
| Sounds Unlimited | 30 days |
| BSWLMDD | None stated |
That is why the label still matters on a no-name design. A maker that prints full specs and a year of cover stands behind the pair after the first sweaty month.

AMOI is a Chinese consumer-electronics name from Xiamen, known in the 2000s for mobile phones. Its logo now sits on budget audio, and AMOI F9 is still the name many people use for the whole design.
No AMOI-branded F9 is on sale in the US right now. Nothing about the AMOI box was unique, which works in your favour: touch buds, a charging case with LED digits, Bluetooth 5, a sweat rating. These four deliver the same recipe, several with newer chips.
An AMOI F9 manual carries over too. The tap patterns on most F9 labels follow the same scheme, one tap for play and pause, holds for the voice assistant, so the F9 manual works whichever logo is on your case.
If you already own an AMOI pair and one bud stopped linking, the fix is the same factory reset every F9 uses. The reset steps bring both buds back to pairing mode.
Sunhai F9 earbuds come from one more factory label on the same design, with none on sale in the US right now. Volt Plus Tech is the label you are most likely to meet instead, and its naming confuses a lot of buyers.
Volt Plus Tech sells one F9 in many boxes, each titled for a device. The F9 with the 2,000mAh case comes in twelve versions, the F9 Mini in twelve more:
The device in the name is a compatibility pointer, nothing more. The buds inside are the same F9 and pair with any Bluetooth phone, tablet or laptop. Pick the version by case and colour, not by the phone on the box.
The range splits three ways: the plain F9 carries the 2,000mAh power-bank case and IPX7 buds, the Mini drops the power bank for a slim pocket case, and the Pro and Pro Touch add a mic-focused build on Bluetooth 5.3 with a lower splash rating.
Volt Plus Tech also backs its F9s with a one-year limited warranty, one of the longer ones on the design.
Volt Plus Tech names its F9 bundles after Samsung Galaxy A-series phones, yet the buds pair with any Bluetooth phone. The 2,000mAh case shows its charge in LED digits and tops up a phone over USB, with IPX7 buds and a one-year warranty.
Grab this pairPeople ask for JBL F9, Samsung F9 and LG F9 earbuds, and none of the three companies makes one. An F9 with a big-brand logo is either a fake or a generic pair named after the phone it is meant for.
Each brand has its own earbud line. JBL sells sport buds under names like Endurance, Samsung's earbuds are the Galaxy Buds, and LG's are the Tone Free range. None of them uses the F9 shell, the LED-digit case or the F9 model code.
A logo does not change the parts. A JBL-badged F9 has the same drivers, chip and battery as any other F9, without the maker's warranty, app or support. The real risk is the price: pay big-brand money for one and you have bought a budget earbud dearly.
Samsung owners have an honest route. The Volt Plus Tech bundles titled for Galaxy phones are open about being compatible F9s, and a Galaxy phone pairs with them like any Bluetooth headset. The pairing steps for Android cover it in under a minute.
| Name on the box | What it means for an F9 | F9 to look at instead |
|---|---|---|
| AMOI | Chinese electronics label on a common F9; no AMOI F9 on sale in the US now | BSWLMDD F9 or MDNS BTH-F9-5 |
| Sunhai | Another factory label on the same design | Volt Plus Tech F9 with 2,000mAh case |
| JBL | JBL makes no F9; a JBL logo on one is not genuine | DCBCODGAL CF9 |
| Samsung | Galaxy Buds are Samsung's earbuds; a Samsung F9 is compatibility naming or a fake logo | Volt Plus Tech F9 for Galaxy phones |
| LG | LG's earbuds are the Tone Free range; no LG F9 | Harigal F9-5C Twin Display |
| Disney | A character print on a standard F9 case | Any F9 with a known label and warranty |
| Volt Plus Tech | US label: F9, F9 Mini and F9 Pro | Its own F9, Mini and Pro Touch |
| MDNS, Huiye, Harigal | Labels behind the F9-5 and F9-5C | Their BTH-F9-5, F9-5 and F9-5C pairs |
Brand status for the US, September 2026.
Disney F9 earbuds do not come from Disney either. Character-printed F9 cases are decoration on the standard buds, and officially licensed Disney earbuds come from accessory makers with their own designs.
If the pair is for a child, the print is the least important part. No F9 lists a volume limiter, while many kids' headphones cap output near 85 decibels, the level hearing guidance treats as the long-exposure ceiling. Set the phone's own volume limit before handing an F9 over.
For your own ears, pick the label by the job. Each of these puts real specs and a clear model on the box:
The version letters matter more than the logo. For routine-by-routine picks, the F9-5 vs F9-5C, Pro and Mini comparison sorts them by routine, and the F9 price bands show what each label costs.
Factories in and around Shenzhen build the F9 as a stock design. Brands such as Volt Plus Tech, MDNS, Huiye, Harigal, BSWLMDD and DCBCODGAL sell it under their own names.
Not in any way that matters. The AMOI F9 uses the same touch buds and LED case; other labels match it and several add Bluetooth 5.3 or bigger cases.
No. JBL's earbuds carry their own names, and a JBL logo on an F9 case is not genuine.
Usually Volt Plus Tech F9s titled for a Galaxy phone, a compatibility name, or pairs wearing a fake Samsung logo. Samsung's own earbuds are the Galaxy Buds.
No. F9s work with the phone's Bluetooth menu alone, and brand apps such as Samsung's Wearable or JBL Headphones do not support them.
Not F9s, same game plan: ear-hook sport buds and LED-display cases from TAGRY, bmani, PocBuds and Jesebang. Grab one when the F9 shape keeps working loose mid-sprint.
