If you want an open-ear design that keeps you aware of traffic, weather and the people around you while you train, choose SilisoundTek Bone Conduction Headphones; if you need true in-ear buds with a charging case, a huge playtime reserve and physical buttons you can work by feel, choose LEEMC Earbuds. Both are built for sweat and rain, both carry an IPX7 water-resistance rating, and both sit in the sport-focused corner of the Bluetooth headphone market — so the real decision comes down to how you want sound delivered to your ears.
• SilisoundTek's biggest strength: bone conduction drivers that transmit sound through your cheekbones and leave your ear canal completely open, so you hear music and your surroundings at the same time.
• SilisoundTek's biggest trade-off: the open design means no ear-tip seal and no passive isolation — and the brand itself notes it is not suitable for swimming despite the waterproof rating.
• LEEMC's biggest strength: a charging case that pushes total playtime to a claimed 80 hours, plus physical buttons and three sizes of silicone ear tips for a custom in-ear fit.
• LEEMC's biggest trade-off: it sits inside your ears, so you get sound isolation but you also block out traffic, voices and warning sounds around you.
• Who SilisoundTek is for: runners, cyclists, hikers and gym-goers who prioritize situational awareness and a bud-free, pressure-free fit.
• Who LEEMC is for: workout and commute users who want long battery life, a secure hooked fit and tactile controls without touching their phone.
The SilisoundTek S800C is the more unusual product of the two. Instead of firing sound into your ear canal, it uses bone conduction drivers with a 20Hz–20,000Hz frequency range and vibrates against your cheekbones, which is why the ear cups sit on your ears rather than inside them. The design is built around a wrap-around titanium alloy frame that can be twisted 360° and springs back into shape, with silicone soft cushions on both sides. That combination is what makes it hold steady during running, cycling or hiking without clamping down on your head.
In my opinion, this is the pick for someone who has ever felt unsafe running on a road with music cranked up, or who simply cannot stand the feeling of silicone pushed into their ear canal for an hour at a time. It's also a reasonable option for anyone who wants to keep one ear open for a coach, a training partner or a podcast and their surroundings. Skip it if you want deep bass isolation on a noisy flight, if you need a sealed fit for maximum volume, or if you were hoping to swim laps with it.
LEEMC Earbuds: Who It's For
The LEEMC S12 goes the traditional route, but with sport-specific reinforcements. Each bud weighs about 0.3oz, and the fit relies on skin-friendly silicone ear hooks over a titanium alloy core — so the bud hangs on your ear rather than relying purely on the tip seal. You get three sizes of silicone ear tips (S/M/L, with M pre-attached), which matters because a correct seal is what makes in-ear sound and passive noise cancellation work at all. The 14.2mm dynamic drivers, 32-ohm impedance, 115dB sensitivity and 55ms latency figure round out a package aimed squarely at workouts and calls.
Battery is where this one separates itself. Each bud is rated for up to 15 hours, and the charging case adds roughly 65 more for a total of about 80 hours. A 15-minute top-up is claimed to give you 2 hours of listening, and a full charge takes about an hour. The case itself has an LED display so you can see the remaining power at a glance, and it's compact — roughly 3.56 x 2.33 x 1.36 inches and about 66.8g. Bluetooth 5.4 gives you a stated range of 10–15 meters, and the physical push buttons on each bud handle volume, playback and voice assistant without you pulling out your phone mid-run.
This is the better fit for someone who trains hard, sweats heavily and wants the buds to disappear into a routine — charge the case once, forget about it for days. It's also the stronger choice for noisy gyms or windy outdoor routes where you actually want the outside world muted. The trade-off is the flip side of that isolation: with buds sealing your ears, you will hear less of what's around you, and the hooked in-ear shape is a different feel from an open frame. If you dislike anything inside your ear canal, this isn't the one.
• Best for situational awareness → SilisoundTek Bone Conduction Headphones. Open-ear bone conduction keeps traffic, voices and warning sounds audible while you listen.
• Best for total battery life → LEEMC Earbuds. About 80 hours total with the case versus 8–10 hours per charge on the SilisoundTek.
• Best for noise isolation → LEEMC Earbuds. Sealed silicone tips plus passive noise cancellation versus an open, isolation-free design.
• Best for the longest single session → LEEMC Earbuds. Up to 15 hours per bud beats the 8–10 hour SilisoundTek rating.
• Best for a bud-free, pressure-free fit → SilisoundTek Bone Conduction Headphones. Nothing enters the ear canal, and the titanium frame flexes and springs back.
• Best for glove-friendly, phone-free control → LEEMC Earbuds. Dedicated physical buttons on each bud for volume, playback and voice assistant.
• Best for fit customization → LEEMC Earbuds. Three ear-tip sizes versus one fixed open-ear frame.
• Best for rain and sweat without a case → SilisoundTek Bone Conduction Headphones. IPX7 protection on a single-piece headset you can rinse and keep moving.
If I had to pick one for a typical outdoor runner, I'd take the SilisoundTek Bone Conduction Headphones. The open-ear design is the whole point — hearing a car, a cyclist or a training partner while your music plays is a real safety advantage, and the titanium frame plus IPX7 rating covers sweat and rain without a case to babysit. I'd only switch to the LEEMC Earbuds if battery life and noise isolation mattered more to me than awareness, because roughly 80 hours of total playtime and sealed in-ear sound are genuinely hard to argue with. Either way, check the current price on Amazon before you decide, since that gap may settle the question for you.
are ipx7 earbuds waterproof
IPX7 means the product is rated to withstand immersion in water up to about one meter for 30 minutes, so sweat, rain and accidental splashes are covered. Both the SilisoundTek headset and the LEEMC earbuds carry IPX7-level water resistance. Note that SilisoundTek states its headset is not suitable for swimming, despite the rating.
can you shower with ipx7 earbuds
An IPX7 rating is generally considered sufficient for showering, since the standard covers short immersion. That said, the specs here don't list showering as an intended use — SilisoundTek explicitly rules out swimming, and LEEMC doesn't mention water activities beyond sweat and workouts. Treat both as sweat-and-rain products rather than pool or shower gear.
LEEMC has the clear edge. Its buds are rated at up to 15 hours each, with the charging case adding roughly 65 hours for about 80 hours total, and a 15-minute charge gives 2 hours of use. SilisoundTek runs 8–10 hours per charge from a 230mAh battery, with magnetic charging and a full top-up in about two hours.
They're different rather than simply better or worse. SilisoundTek uses bone conduction drivers with a 20Hz–20,000Hz range and an open-ear fit, so there's no ear-tip seal and no passive isolation. LEEMC uses 14.2mm dynamic drivers with 32-ohm impedance, 115dB sensitivity and passive noise cancellation, which gives in-ear impact but blocks outside sound. Which you prefer depends on whether you want awareness or isolation.
