SANOTO makes my pick for bone conduction earbuds with microphone for PC when swimming is part of the plan: its S710 combines IPX8 protection with onboard music storage. ASUS is the runner-up, with dual wireless modes and a bone-conduction AI mic that better suit PC gaming and calls.
• SANOTO Swimming Headphones — best for pool sessions; pick this if you want IPX8 water protection and 8GB of onboard music storage.
• SANOTO Swimming Headphones — best for swimming with a phone-free playlist; pick this if you want the same S710 features in a blue version.
• ASUS ROG Cetra True — best for PC gaming and team chat; pick this if you want Bluetooth, 2.4 GHz connectivity, and a bone-conduction AI mic.
• ASUS ROG Cetra True — best for switching between PC and phone; pick this if you want the same dual-mode setup in a white version.
The SANOTO S710 is the swimming-first choice in this guide. Its combination of IPX8 water protection and built-in 8GB MP3 storage addresses a specific problem: Bluetooth cannot be relied on underwater. The product guidance says to switch to MP3 mode for swimming and turn off the phone’s Bluetooth.
That makes it a useful option for laps, surfing, or other water activities where a phone connection is not practical. The S710 also supports Bluetooth 5.4 for use out of the water, with up to 8 hours of playback in Bluetooth mode and up to 12 hours in MP3 mode. Its storage supports MP3, FLAC, WMA, WAV, and APE files.
The in-ear design uses soft silicone ear hooks and includes replacement ear tips. The hooks are described as compatible with swimming caps, goggles, and earplugs, which could help keep the headphones settled as you gear up. Button controls handle operation, and the package includes two magnetic charging cables. The listed charge time is 2 hours; the instructions specify using the included cable.
The trade-off is its focus. This is not the model I would choose as my main PC headset: the published features do not list a PC-focused USB dongle, a microphone feature, or a dedicated call setup. It also uses an in-ear, closed-back design, so it is not the open-ear style some people expect from bone-conduction headphones. I’d choose it for swimming and offline listening, not as an all-purpose computer headset.

This is another listing for the SANOTO S710 swimming headphones, with the same core appeal: IPX8 protection, Bluetooth 5.4, 8GB of music storage, and an MP3 mode for underwater listening. Its key difference in the listed design is the blue finish; the other S710 entry is black.
For swimming, the practical routine is clear. Load music onto the built-in player, switch to MP3 mode before getting in the water, and leave the phone’s Bluetooth off while submerged. The listed supported formats include MP3, FLAC, WMA, WAV, and APE. That gives the headphones a role beyond ordinary wireless earbuds: they can play stored audio without depending on a live phone connection.
The silicone ear hooks are intended to stay in place during movement and work with swimming gear such as caps and goggles. Button controls keep the operation physical rather than touch-based, and the package includes replacement ear tips and charging cables. The listed battery life reaches up to 12 hours in MP3 mode, compared with up to 8 hours in Bluetooth mode.
There are some details to keep in mind. The data for this version lists environmental noise cancellation, but does not describe a microphone or specify how that feature works. Bluetooth is also not the mode to use underwater; the product instructions call for MP3 mode instead. I’d pick this version if the blue design is the preference and pool use is the priority. For a voice assistant headband headphones for PC setup, though, the ASUS options are a more relevant fit.
The black ASUS ROG Cetra True Wireless SpeedNova is the most PC-oriented choice here. It pairs Bluetooth with a 2.4 GHz USB-C dongle, and its bone-conduction AI microphones are intended to isolate voice from background noise for communication. For PC gaming, that combination is more directly useful than the SANOTO swimming models’ onboard MP3 player.
The two wireless modes serve different jobs. Bluetooth supports PC, Mac, mobile devices, and Nintendo Switch; the 2.4 GHz dongle mode also supports PlayStation 4 and PlayStation 5. Hybrid multipoint can connect to two devices through Bluetooth and 2.4 GHz at once, which may suit someone gaming on a computer while keeping a phone connected for calls. The included dongle has a USB-C connection and a USB-C-to-USB-A adapter.
For sound and focus, ASUS lists 24-bit/96 kHz audio in 2.4 GHz mode, Dirac Opteo processing, and adaptive active noise cancellation. The ANC is designed to adjust to the wearer’s fit and surrounding noise. Battery life is listed as up to 46 hours in Bluetooth mode with RGB lighting off, and a five-minute in-case charge is stated to provide up to an hour of use. The case supports USB-C and wireless charging.
ASUS ROG Cetra True
The white ASUS ROG Cetra True has the same central feature set as the black version: Bluetooth and 2.4 GHz wireless modes, a USB-C dongle with an adapter, adaptive ANC, and bone-conduction AI microphones for voice pickup. Its distinguishing listed feature is the white color, including a white carrying case.
The PC connection options make it easier to match the earbuds to different setups. Bluetooth supports PC and Mac along with mobile devices and Nintendo Switch. The 2.4 GHz mode adds PS4 and PS5 support, and the hybrid multipoint feature allows a Bluetooth device and a 2.4 GHz device to remain connected together. That is handy in principle for moving between game audio and phone calls without reconnecting each time.
ASUS also lists Dirac Opteo audio processing and high-resolution audio in 2.4 GHz mode. Adaptive ANC is designed to respond to ear fit and ambient noise, while the microphones target clear team chat and streaming communication. Battery life is listed as up to 46 hours in Bluetooth mode with RGB lighting off; a five-minute charge in the case is described as enough for up to an hour of use. The case can charge by USB-C or wirelessly.
The trade-offs mirror the black model. These are gaming earbuds, not a swimming headset, and they lack a headphone jack. The specifications don’t establish them as the best comfortable in ear earbuds for pc for every listener; fit is personal, though the package includes three sizes of ear tips. I’d choose the white version if its appearance suits your setup, while treating its connectivity and microphone features as the reasons to buy—not the color alone.
How We Picked
I compared the published features and specifications for water use, stored playback, PC connectivity, microphones, and battery claims.
The order is my independent editorial opinion, based on which model better fits each stated use case.
No brand paid for placement.
The product instructions say to use MP3 mode underwater and turn off the phone’s Bluetooth. Bluetooth is not the specified mode for submerged use.
The ASUS ROG Cetra True models list a 2.4 GHz USB-C dongle, PC compatibility, and bone-conduction AI microphones. Those features make them the more PC-focused choices in this guide.
Yes. Both S710 listings specify 8GB of storage and support MP3, FLAC, WMA, WAV, and APE files. Their listed playback time is up to 12 hours in MP3 mode.
The ASUS charging case supports USB-C charging, as well as wireless charging. The SANOTO S710 uses the included magnetic charging cable, so it is not the match for someone specifically seeking USB C charging on ear headphones for PC.
For PC, my recommendation is the black ASUS ROG Cetra True: its 2.4 GHz dongle, Bluetooth multipoint, and bone-conduction AI mic make it the more capable fit for gaming and calls. Choose SANOTO instead when swimming and stored MP3 playback matter most.
