If you want a bedside charging hub that also tells the time, choose IHAO 4in1; if you need headphones you can actually swim in, choose KESIEME Swimming Headphones. These two share almost nothing except a glowing LED readout — one lives on your nightstand, the other lives on your head in the pool.
• IHAO 4in1 — biggest strength: it replaces four separate nightstand gadgets with one magnetic 15W wireless charger, a digital alarm clock, a mirror-finish LED display, and a 5V/1A USB-A port for a fourth device.
• IHAO 4in1 — biggest trade-off: it is a stationary desk/bedside device, not something you take to the gym or the pool, and it charges devices rather than playing audio.
• KESIEME Swimming Headphones — biggest strength: IPX8 waterproofing rated for depths up to 99 feet, bone conduction open-ear audio, and built-in 32GB memory so you can swim with music and no phone.
• KESIEME Swimming Headphones — biggest trade-off: open-ear bone conduction deliberately lets ambient sound in, so it is not the choice for isolating yourself in a noisy office or on a plane.
• Pick IHAO 4in1 if you want your nightstand decluttered and your phone, earbuds, and watch topped up overnight.
• Pick KESIEME Swimming Headphones if your priority is listening to music while swimming, running, or cycling.
The IHAO 4in1 is a nightstand organizer first and a gadget second. It bundles a magnetic wireless charger, a digital alarm clock, a large mirror-style LED display, and a USB-A charging port into a single unit. That magnetic mount holds your Qi phone at a viewing angle, which matters more than it sounds: it means your phone becomes a clock, a video screen, or a bedside control panel instead of a loose slab sliding around the table.
Charging is the core of it. The magnetic pad pushes 15W fast wireless charging to a compatible phone, and there are dedicated spots for wireless earbuds and a smartwatch. A fourth device — a tablet, a second phone, whatever — can hang off the 5V/1A USB-A port. The spec sheet lists an intelligent protection circuit against overcharging, overheating, and short circuits, which is exactly the kind of thing you want in a device that sits plugged in all night next to your pillow.
The display is the part people underestimate. When it is off, the panel works as a mirror. When it is on, it shows the time, alarm settings, and real-time temperature, with adjustable brightness so it does not blast your bedroom at 2 a.m. Setting an alarm takes seconds.
Who should buy it: anyone whose nightstand currently holds a charger, a clock, a loose cable, and a smartwatch puck. Also good for a home office desk where you want one tidy charging station. Who should skip it: travelers and swimmers. It is a stationary device with a 12V input, and it does not play a single note of audio.
The KESIEME S10 is built around one idea: music where normal earbuds die. It is IPX8 waterproof, sweatproof, dustproof, and moistureproof, and the spec sheet says it is tested to withstand depths of up to 99 feet underwater. That is the headline. If you swim laps, this is the entire reason to own it.
The audio approach is bone conduction. Sound travels through your cheekbones to your inner ear, bypassing the eardrum, with a 15mm bone conduction driver and 16-ohm impedance. The open-ear design means you hear your music and your surroundings at the same time — genuinely useful when you are cycling near traffic or running on a shared path. The description also mentions bass enhancement and sound-leakage suppression technology, plus CVC call noise reduction with a dual-microphone setup.
The LED digital display on this one is functional, not decorative. After you power it on, it shows remaining battery and the current mode — Bluetooth or MP3 — so you always know where you stand. That second mode matters: there is 32GB of built-in memory holding 10,000+ songs, so you can leave your phone in the locker and still swim with a full playlist. Bluetooth 5.4 handles wireless connections to Android, iOS, and Windows devices when you do want your phone.
Battery is 10 hours of music or talk time with 300 hours of standby, and a full charge takes about 2 hours through a magnetic waterproof charging interface. The neckband is memory titanium alloy — 360° bendable, compression-resistant — and the whole thing weighs 37.4g, which the sheet notes is light enough to wear with glasses. The box includes swimming earplugs.
Who should buy it: lap swimmers, open-water swimmers, runners, and cyclists who want audio without blocking the world out. Who should skip it: anyone who wants noise isolation. Active noise cancellation is listed, but bone conduction by design leaves your ear canal open — that is the trade for safety.
Side-by-Side: Which Should You Choose?
• Best for a tidy nightstand → IHAO 4in1. One unit replaces a charger, a clock, a mirror, and a spare USB port.
• Best for battery life away from an outlet → KESIEME Swimming Headphones. 10 hours of playback and 300 hours of standby on a 2-hour charge.
• Best for charging multiple devices at once → IHAO 4in1. Phone, earbuds, watch, and a fourth device over USB-A, all from one station.
• Best for phone-free listening → KESIEME Swimming Headphones. 32GB of onboard memory means no phone required.
• Best for workout safety → KESIEME Swimming Headphones. The open-ear design keeps you aware of traffic and other people.
• Best for a bedroom or office → IHAO 4in1. Time, alarm, temperature, and mirror display in a design meant to sit on a surface.
• Best for wearing with glasses → KESIEME Swimming Headphones. The 37.4g titanium neckband is built to be worn alongside them.
In my opinion, these are not competitors — they solve different problems, and the honest answer is that most people comparing them should figure out which problem they actually have. If you are shopping for a swim or workout companion, I would buy the KESIEME Swimming Headphones: IPX8 waterproofing, 32GB of built-in storage, 10 hours of playback, and an LED display that shows battery and mode is a coherent package for anyone who moves. If your real frustration is a messy nightstand full of half-charged devices, I would buy the IHAO 4in1 instead, because no pair of headphones will ever charge your watch or show you the temperature. Buy for the job, not the spec sheet.
FAQ
are earbuds considered electronics
can you connect earbuds to a tv
It depends on the TV. The KESIEME Swimming Headphones are listed as compatible with Android, iOS, and Windows Bluetooth devices, so a TV with Bluetooth audio output can pair with them. If your TV has no Bluetooth transmitter, you would need an adapter, since these connect wirelessly over Bluetooth rather than through a cable.
should i get black or white earbuds
The KESIEME Swimming Headphones are offered in black, and the IHAO 4in1 is listed in black as well. Color here is purely aesthetic — the spec sheets show no functional difference between finishes, so pick whichever matches the space or gear you already own. On a nightstand, a darker finish tends to hide dust and cable scuffs better.
No. The 32GB of built-in memory holds 10,000+ songs, so you can load music ahead of time and swim in MP3 mode with no phone nearby. Bluetooth mode is there when you do want to stream or take calls, and the LED display tells you which mode you are in.
