How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of true wireless sport earbuds that stay put through sweat, rain and long runs, choose chalvh Ear buds; if you need a single-ear Bluetooth headset built for all-day calls, trucking and driving, choose Atheewon Headset. Both carry an IP7/IPX7 waterproof rating and Bluetooth 5.4, but they are aimed at completely different jobs.
• chalvh Ear buds — biggest strength: A true-wireless stereo pair with ear hooks, 3 g per bud, 14 mm titanium-diaphragm drivers, 50 hours of total playback and a charging case with an LED battery display.
• chalvh Ear buds — biggest trade-off: It's a two-earbud music-first design with touch controls, so it's less convenient than a single headset if you mostly make calls while driving.
• Atheewon Headset — biggest strength: A single over-ear earpiece with a flip-up boom microphone, rotating ear hooks, up to 18 hours of talk time and up to 120 hours total with the case — built for voice.
• Atheewon Headset — biggest trade-off: It's mono audio (one ear), so it isn't the pick for immersive stereo music listening or running with both ears covered.
• Who each pick is for: chalvh for runners, gym-goers and music listeners who want two wireless buds; Atheewon for drivers, truckers, couriers and business users who live on calls.
The chalvh Ear buds are a stereo true-wireless set with an in-ear fit, soft ear hooks and a claimed weight of just 3 g per bud. The spec sheet lists Bluetooth 5.4 with a high-sensitivity FPC antenna, a 15-metre transmission range, latency reduced to around 100 ms and roughly 30% lower power consumption than the previous generation. In practice that combination is what you want for video and gaming: low latency keeps audio and picture in sync, and the longer range means you can leave your phone on a bench or in a bag while you move around.
Audio is handled by 14 mm titanium-diaphragm dynamic drivers with AAC/SBC encoding and a 20 Hz–20,000 Hz frequency range, so it's a full-range stereo presentation rather than a voice-only one. Four microphones with ENC are listed to cut around 80% of ambient noise on calls, which is genuinely useful outdoors where wind and traffic fight your voice. Battery is the headline: up to 8 hours on a single charge and up to 50 hours total with the case, charged over USB-C in about 1.5 hours, with a smart LED display on the case showing remaining charge.
The waterproofing claim is IP7 nano-coating, described as resistant to sweat and rain — exactly the protection you'd expect from sport earbuds. Controls are touch-based on the outer surface: tap to play/pause, change volume, skip tracks, take calls or trigger your voice assistant. Compatibility covers iOS 9.0, Android 5.0 and up.
Who should skip it: if you take most of your calls one-eared while driving, or you want physical buttons you can find by feel without looking, this isn't the shape or control scheme you're after.
Atheewon Headset: Who It's For
The Atheewon Headset is a different animal entirely: a single over-ear Bluetooth earpiece in black, with rotating ear hooks and a flip-up microphone that lets you switch it between your left and right ear. It ships with three sizes of ear tips (S/M/L) to spread pressure evenly, and the open-ear, over-ear placement is designed for all-day wear with minimal fatigue — the kind of thing you put on in the morning and forget about.
The core pitch is voice. It uses Bluetooth 5.4 for a faster, more stable connection with lower power draw, and pairs with ENC noise-reduction technology aimed at filtering surrounding noise so calls stay clear in a business meeting, on a conference line, or behind the wheel of a truck. The 14.2 mm dynamic driver handles music too, and the sheet describes a clear, lifelike presentation — but it's a mono earpiece, so treat music as a secondary use.
Battery numbers are the standout: up to 18 hours of talk time on a single charge and up to 120 hours total when you top up from the charging case. It also charges directly over USB-C in about 1.5 hours, and the case has an LED display showing remaining charge. Note the manufacturer's own caveat that playback time varies with volume.
Controls are physical push buttons for answering, hanging up, volume and music playback — a deliberate choice for busy work scenarios where you can't look at the earpiece. Water resistance is listed as IP7, resisting sweat, rain and other liquids. Compatibility spans iOS, Android and Windows, and the box includes the headset, three ear tips, a USB-C cable (no AC adapter), a user manual and a wireless charging case.
Who should buy it: drivers, truckers, delivery and courier workers, and anyone in sales or support who spends hours on the phone and wants one ear free.
Who should skip it: if you want stereo music, spatial audio or a sealed in-ear fit for the gym, this is the wrong tool — its strength is hands-free calling, not immersion.
• Best for running and workouts → chalvh Ear buds. Two 3 g buds, ear hooks, soft ear arches and an IP7 sweat-and-rain coating are built for movement.
• Best for all-day phone calls → Atheewon Headset. A flip-up boom mic, ENC noise reduction and up to 18 hours of talk time per charge.
• Best for total battery life → Atheewon Headset. Up to 120 hours with the case versus up to 50 hours on the chalvh, though the Atheewon figure includes talk time and the chalvh figure is playback.
• Best for stereo music listening → chalvh Ear buds. 14 mm titanium-diaphragm drivers, AAC/SBC encoding and a 20 Hz–20,000 Hz range across both ears.
• Best for driving and trucking → Atheewon Headset. Over-ear with rotating hooks, physical buttons and left/right ear switching without taking your eyes off the road.
• Best control scheme for gloved or busy hands → Atheewon Headset. Push buttons beat touch sensors when you can't look at the device.
• Best for low-latency video and gaming → chalvh Ear buds. Bluetooth 5.4 with roughly 100 ms latency and a 15-metre range.
• Best waterproofing story for either use → a tie. Both list an IP7 rating against sweat, rain and splashes, so pick on form factor, not on water resistance.
In my opinion, the chalvh Ear buds are the better buy for most people, because a stereo true-wireless pair with ear hooks, 50 hours of total playback and a 3 g-per-bud fit covers music, workouts and calls in one product. I'd only steer you to the Atheewon Headset if your day is defined by voice — driving, dispatching, conference calls — where the boom mic, physical buttons, ear-swapping design and up to 18 hours of talk time matter far more than stereo sound. Match the shape to your routine and either one will do its job. Check the current price on Amazon before you commit, since that's the one thing specs can't tell you.
are ipx7 earbuds waterproof
IPX7 means the device is rated to withstand immersion in water under defined test conditions, not just splashes. Both products here list an IP7/IPX7 rating, and the chalvh sheet specifically describes a nano coating resistant to sweat and rain. In practice that covers rain, sweat and accidental splashes — it is not a licence to swim with them.
can you shower with ipx7 earbuds
An IPX7 rating is about water immersion resistance, so a shower is technically within what the rating covers — but neither sheet makes a showering claim, and soap, shampoo and hot steam are not part of the standard test. I'd treat both as sweat-and-rain protection rather than shower-proof, and dry them before putting them back in the case.
Both use ENC noise reduction and multiple microphones. The chalvh has four microphones with ENC listed to cut around 80% of noise on a stereo pair; the Atheewon uses a single over-ear earpiece with a flip-up boom mic and up to 18 hours of talk time. For long call-heavy days the Atheewon is the more purpose-built tool.
It depends on how you count. The chalvh lists up to 8 hours per charge and up to 50 hours total with the case for playback. The Atheewon lists up to 18 hours of talk time per charge and up to 120 hours total with the case. For total runtime the Atheewon wins on paper; for music playback specifically, the chalvh figure is the relevant one.
