If you want everyday wireless earbuds with long battery life and a stable Bluetooth connection for commutes, calls and workouts, choose SGNICS Huawei Honor 30; if you need headphones that survive being submerged and play music underwater while you swim, choose TOHUNZO IP68.
• SGNICS Huawei Honor 30 — biggest strength: 31 hours of total battery life (7 hours per charge, plus 3–4 recharges from the case), a 13mm dynamic driver and Bluetooth 5.3 with a 12-meter range.
• SGNICS Huawei Honor 30 — biggest trade-off: IPX4 only, so it shrugs off sweat and light rain but is not built for swimming or submersion.
• TOHUNZO IP68 — biggest strength: IP68 waterproofing rated for immersion up to 20ft for up to 16 hours, plus 32GB of built-in memory so you can listen with no Bluetooth at all.
• TOHUNZO IP68 — biggest trade-off: underwater listening only works in MP3 mode, because Bluetooth signals don't transmit through water — and there's no charging case to top it up on the go.
• Buy the SGNICS if you want a conventional true-wireless pair for daily life; buy the TOHUNZO if pool or open-water swimming is the whole point.
The SGNICS Huawei Honor 30 is a classic true-wireless earbud setup, and it leans hard into the things most people actually use earbuds for: battery life and signal reliability. Each bud runs about 7 hours, and the charging case adds roughly three to four more full charges, for a claimed 31 hours with both earbuds in use. The spec sheet also lists a 28-hour average battery life, so treat the total as "somewhere in the high twenties to low thirties" depending on volume and how you count it. Either way, that's a week of commuting without hunting for a cable.
Sound comes from a 13mm compound-diaphragm dynamic driver covering 20Hz–20,000Hz. A larger driver in an in-ear shell usually translates to fuller low end and more body in the mix, which suits pop, podcasts and gym playlists. Bluetooth 5.3 keeps the connection stable and efficient, and the stated 12-meter range means you can leave your phone on a bench and walk around a room. The passive noise cancellation is exactly that — passive — so isolation comes from the in-ear seal rather than active circuitry. Touch controls handle calls, playback and voice assistant, and the case auto-reconnects to your last device, with only the very first pairing done manually.
Who should buy it: anyone who wants a lightweight in-ear pair (3.8g per bud, rounded-tip in-ear design) for commuting, calls, study sessions and sweaty gym work. The IPX4 rating handles splashes, sweat and light rain, which covers most indoor and fair-weather training. Teens, adults and seniors are all listed in the age range, and the touch controls are simple enough for non-technical users.
TOHUNZO IP68: Who It's For
The TOHUNZO IP68 is built around one job: letting you hear music while you're actually in the water. The IP68 rating means it can be immersed up to 20 feet deep for up to 16 hours, and the brand claims clear sound even underwater. That's a fundamentally different class of protection from IPX4.
The catch is physics, not marketing: Bluetooth doesn't travel through water, so the TOHUNZO carries 32GB of built-in memory — enough for roughly 10,000 songs or audiobooks — and you switch to MP3 mode before you get in. The brand's instructions say to hold both volume buttons at once to enter that mode. It also does normal Bluetooth 5.3 for land-based use, so it's a dual-purpose device rather than a swimming-only gadget.
The design choices are swimming-specific. Flexible, soft ear hooks hold the buds in place and, per the brand, help keep water out of your ears — and they avoid the cheekbone vibration that bone-conduction models can cause over long sessions. It's an in-ear shape in black plastic, with active noise cancellation listed for the headset function, and a claimed 16 hours of playtime from a 1.5-hour charge. There's no charging case, so you charge the buds themselves, and there's no headphone jack.
Who should buy it: swimmers, triathletes, and anyone who trains in a pool or open water and wants audio that keeps working. It also suits people who want a screen-free MP3 player built into their earphones for runs and gym sessions where they'd rather not carry a phone.
Who should skip it: anyone who mainly wants a pocketable everyday pair. With no case and a charge time of 1.5 hours, it's less convenient for all-day, on-the-go top-ups than a cased true-wireless set. And if you never submerge your headphones, you're paying in convenience for protection you won't use.
Side-by-Side: Which Should You Choose?
• Best for total battery life with a case → SGNICS Huawei Honor 30. 31 hours total (7 per charge plus 3–4 case recharges) versus 16 hours per charge.
• Best for phone-free listening → TOHUNZO IP68. 32GB of internal storage for roughly 10,000 tracks; the SGNICS has no onboard memory.
• Best for everyday wireless convenience → SGNICS Huawei Honor 30. Auto-reconnect case, touch controls and a 12-meter Bluetooth 5.3 range.
• Best for gym, running and sweaty workouts → either, but for different reasons. The SGNICS handles sweat with IPX4; the TOHUNZO adds ear hooks and active noise cancellation.
• Best for richer everyday sound on paper → SGNICS Huawei Honor 30. A 13mm dynamic driver with a 20Hz–20,000Hz range and a passive-seal in-ear fit.
• Best for long sessions without a charger nearby → TOHUNZO IP68. A single 1.5-hour charge is claimed to deliver 16 hours.
• Best for a first true-wireless pair → SGNICS Huawei Honor 30. Simpler, lighter and designed for automatic reconnection.
In my opinion, most people should buy the SGNICS Huawei Honor 30. It covers the everyday jobs — commuting, calls, study, gym — with the longest battery figure in this comparison, a bigger driver, and a case that keeps it topped up without thinking. The TOHUNZO IP68 is the better product only if you genuinely swim with music; in that one scenario it wins outright, because IPX4 simply can't go where IP68 goes. If you split your time between the pool and the pavement, the TOHUNZO's Bluetooth mode makes it a reasonable single-pair compromise, but you give up the case and the longer runtime. Decide which one describes your week more often, and buy that one.
FAQ
can i wear waterproof headphones in the shower
are headphones waterproof
Most aren't, strictly speaking. IPX4 on the SGNICS means splash and sweat resistance only, while IP68 on the TOHUNZO means it can actually be immersed — and even then, the TOHUNZO needs MP3 mode underwater because Bluetooth can't transmit through water.
can i use bluetooth underwater
No. Bluetooth signals don't travel through water, which is why the TOHUNZO IP68 has 32GB of built-in memory and an MP3 mode you switch to before swimming. Its Bluetooth 5.3 is for land use — gym, runs, calls and everyday listening.
how long do these headphones last on a charge
The SGNICS Huawei Honor 30 runs about 7 hours per charge and the case adds three to four more recharges, for a claimed 31 hours total. The TOHUNZO IP68 is listed at 16 hours of playtime from a 1.5-hour charge, with no case.
