IPX7 buds you can rinse under the tap, a sealed charging port, twin LED screens for case and buds, and a pocket-size magnetic case that refills the buds about 25 times.
Leg day is done, the buds are slick with sweat and the shower is calling. With the Harigal F9-5C Twin Display, the buds can go under the tap. They carry an IPX7 rating, and Harigal says outright that they can be washed directly.
IPX7 is tested with the device under a metre of fresh water for half an hour. For a pair of buds, that translates to sweat, rain and the moment one drops into the sink. It is not a swimming rating, so skip the pool and the shower itself.
The case gets its own guard: a soft rubber dust plug over the charging port. Grit and splashes stay off the contacts, which is what keeps a case charging months down the line.
Never charge a wet bud. Current plus moisture corrodes the contacts fast.
How water ratings from IPX3 to IPX7 play out across the range is covered in the F9 specs breakdown.

Harigal rates the Twin Display case for about 25 refills. That adds up to roughly 120 hours of music or 150 hours of talk time, on the maker's own testing. For most weeks, the case will outlast your memory of when you last charged it.
Twin LED screens keep it honest. One shows the case percentage; the other tracks the left and right buds as they charge. You see the reserve before a run, not halfway through it.
| Figure | What it means |
|---|---|
| About 25 | Full bud refills from one case charge |
| About 120 hours | Music time with the case |
| About 150 hours | Talk time with the case |
| Auto cut-off | Charging stops at full, so overnight is safe |
Those figures cover the buds only. The case has no phone-charging output listed, so it is a bud charger, not a power bank. If your phone fades before the day ends, the Volt Plus Tech F9 with its 2,000mAh power bank is the better fit.
Getting the most out of each case charge:
Talk time runs longer than music time because calls use less power than streaming full stereo. If most of your day is calls on one bud, expect the case to stretch even further.
The auto cut-off makes overnight charging a non-event. Plug it in by the bed and forget it.
The F9 charging guide lines this case up against the power-bank F9s.
Mid-run on the treadmill, one hand on the rail, one bud needs to come out. The Twin Display lid is held shut by magnets rather than a stiff plastic snap. It flips open one-handed and closes with a click you can feel.
No hard pressing means no broken hinge after a few months in a gym bag. Each bud clicks into its cradle and charging begins the moment the contacts touch, so you do not need to line anything up by eye.
The controls are just as one-handed. Each bud has its own fingerprint panel, and a blue light ring confirms every touch:
The blue ring is useful on a loud gym floor. When the music is too loud to hear a prompt, the light tells you the tap landed.
The Bluetooth 5.0 chip talks to iPhones, Android handsets, tablets and laptops alike. Harigal says it holds through a jacket pocket, a treadmill rail or a walk across the room. That is one room of range in practice, enough for a phone parked on the treadmill shelf.
The glossy black case slips into a jeans pocket. Prompt language and other control quirks get their own section in the F9 manual guide, and the F9 reset guide helps when one bud goes silent.
The Twin Display and the Mirror Case are Harigal's two F9-5C pairs. They share the magnetic cradles, fingerprint panels and pocket-size case. The split is water versus gaming.
| Twin Display | Mirror Case | |
|---|---|---|
| Water | IPX7, rinsable | No IPX number |
| Bluetooth | 5.0 | 5.3 |
| Readout | Twin screens | Three figures, lid shut |
| Game mode | Not listed | Four taps |
| Case runtime | About 120 hours of music | Not quoted |
| Port plug | Yes | Not listed |
Choose the Twin Display if:
Gamers who want Bluetooth 5.3 should take the Harigal F9-5C Mirror Case.
Outside Harigal, two other IPX7 pairs are worth a look. DB LLC offers its F9-5C in white, with a digital display. The MDNS BTH-F9-5 adds 8mm drivers, buds rated for 30 minutes under water and a 2,000mAh case with an LED readout.
Chip age is the Twin Display's one soft spot. Bluetooth 5.0 does the job for music and calls, but 5.3 pairs tend to reconnect faster and hold steadier in a packed train carriage. If your commute is crowded, weigh that against the water rating.
Before you buy, check one thing: whether you need the case to charge your phone. The Twin Display does not list that, so pair it with a small power bank if your phone runs low.
Yes. They are rated IPX7 and Harigal says they can be washed directly. Dry them fully before charging, and leave them in the locker when you swim.
About 25 refills, roughly 120 hours of music or 150 hours of talk time, per the maker.
One shows the case percentage; the other tracks the left and right buds as they charge.
No game mode is listed. For that, the Harigal F9-5C Mirror Case switches modes with four taps.
Yes. Charging cuts off automatically at full.
