If you want a swimming headset with IP68 waterproofing, 32GB of built-in music storage, and Bluetooth 6.0, choose SilisoundTek IP68; if you need an open-ear swimming option with Bluetooth 5.4 and a simpler 8GB offline library, choose sunvito Bone Conduction Swimming. For webinars, neither model is a conventional closed-ear headset with a stated microphone specification, so I’d choose SilisoundTek only if its larger offline library and multi-device connection matter more than webinar-specific call features.
• SilisoundTek IP68: Its key strength is the combination of IP68 waterproofing, 32GB MP3 storage, and Bluetooth 6.0 with multi-device connection. Its trade-off is that underwater listening requires switching to MP3 mode and loading music ahead of time.
• sunvito Bone Conduction Swimming: Its key strength is a straightforward swimming setup with IPX8 waterproofing, Bluetooth 5.4, and MP3 playback. Its main trade-off is 8GB storage, a smaller offline library than SilisoundTek’s.
• Both use bone conduction and keep the ears open; neither has a stated microphone specification for webinar calls.
• Choose SilisoundTek if you want more local music storage and a longer stated Bluetooth range; choose sunvito if its 8GB library and open-ear swim-focused design cover your needs.
SilisoundTek’s most practical distinction is how it combines wireless listening outside the water with independent MP3 playback in it. The headphones have Bluetooth 6.0 and a stated range of up to 13 meters, plus support for connecting multiple devices. That may suit someone who switches between a phone and another compatible device rather than wanting to pair from scratch each time. The listing does not specify the details of how multi-device switching works, so I would not assume it means seamless handoff between active audio sources.
For swimming, the built-in 32GB MP3 player matters more than Bluetooth: the product description says to load music in advance and switch to MP3 mode underwater. Its stated capacity is more than 8,000 songs, giving it considerably more room for an offline library than the sunvito model. The rating is IP68, and the product is also presented for activities such as surfing, diving, running, hiking, and skiing. Bone conduction leaves the ears open, which is useful when you want to remain aware of your surroundings during land-based exercise. It does not mean the headphones block outside noise.
Battery life is listed as 8–10 hours of music playback or calls, with a separate product-information figure of 8 hours of average battery life. Full magnetic charging is described as taking about 1.5–2 hours, while another listed figure says 1.5 hours. I’d plan around the more conservative end rather than treat the longer playback figure as guaranteed in every situation. For a buyer who wants a larger swim-ready library, multi-device Bluetooth, and open-ear listening for workouts, that feature mix is the main case for SilisoundTek.

sunvito is built around swimming and underwater training, with IPX8 waterproofing and two playback modes. Bluetooth 5.4 supports everyday wireless listening, while MP3 mode provides offline playback for swimming. As with SilisoundTek, the practical implication is that underwater listening depends on music stored directly on the headphones, not on a phone streaming over Bluetooth. Plan to prepare your listening library before getting in the water.
Its built-in 8GB storage is listed as enough for up to 2,500 songs. That gives a swimmer room for a selection of familiar tracks or training playlists, though it is a tighter library than SilisoundTek’s 32GB. The open-ear bone-conduction design avoids covering the ear canal, and the product description says the fit is intended to stay secure during swim sessions and outdoor workouts. Those details make it a reasonable fit for someone who wants a simple, dedicated swim-and-training device rather than a large music library on their headphones.
sunvito lists up to 8 hours of playtime and magnetic charging, with a stated charge time of 2.5 hours. Bluetooth range is listed as 10 meters. Its controls are button-based, and its noise control is listed as none. For a buyer who wants basic playback modes and physical buttons, that simplicity may be welcome. It also means you should not expect active noise reduction based on the available product information. The sheet does not give a microphone specification, so I would not choose it specifically as a webinar call headset.
Who should skip it: Skip sunvito if you want more offline storage, a longer stated Bluetooth range, or specified multi-device connection support.
• Best for a larger offline swim library → SilisoundTek IP68. Its 32GB storage is listed for more than 8,000 songs, compared with sunvito’s 8GB and up to 2,500 songs.
• Best for a simpler-sized playlist collection → sunvito. Its storage may be enough if you load only a few playlists for swimming and workouts.
• Best for the longer stated Bluetooth range → SilisoundTek IP68. It lists up to 13 meters; sunvito lists 10 meters.
• Best for newer listed Bluetooth version → SilisoundTek IP68. Its Bluetooth version is 6.0, while sunvito lists 5.4. That difference alone does not establish sound quality or connection performance in every setting.
• Best for multi-device connection support → SilisoundTek IP68. Its product information explicitly mentions support for connecting multiple devices; sunvito’s sheet does not state this feature.
• Best for a straightforward swim-training routine → sunvito. Its two modes separate everyday Bluetooth listening from stored MP3 playback for underwater use.
• Best for longer stated playback potential → SilisoundTek IP68. Its description gives 8–10 hours for music or calls, although the product-information field separately lists an 8-hour average. sunvito states up to 8 hours.
• Best for webinar use → neither is a clear headset choice. Both are open-ear bone-conduction headphones, but neither sheet specifies a microphone. SilisoundTek’s multi-device support may be useful around multiple devices, but that is not proof of webinar call compatibility or microphone quality.
Buying Considerations
Next, consider how much music you actually want stored on the headphones. SilisoundTek’s 32GB capacity is the clear advantage for a broad library; sunvito’s 8GB may be sufficient if you keep a smaller set of swim playlists. Storage capacity is not the same thing as a guarantee about file compatibility or the exact number of songs you can fit, so treat the song counts as estimates provided for each product.
For workouts outside the water, the open-ear bone-conduction design is a shared feature, not a reason to pick one over the other. It leaves the ears uncovered, which can help you stay aware of surrounding sounds, but it also means neither is designed to seal out nearby noise. SilisoundTek lists Hybrid Noise Cancellation, while sunvito lists no noise control; those labels do not make either one a conventional noise-isolating earbud, and the provided information does not explain how SilisoundTek’s noise-control feature works with its open-ear design.
Webinars call for a separate check. If you are searching for the best hifi stereo earphones for webinars, a headset for webinars, or the best multipoint in ear headphones for webinars, these swim-focused products do not supply enough information to make that specific call. Neither sheet states microphone performance, conferencing controls, or webinar software compatibility. SilisoundTek does list calls among its battery-use claims and supports connecting multiple devices, but that still does not establish that its microphone suits work meetings. If webinar audio is your main priority, look for a product with explicit microphone and call features before choosing either of these.
Finally, compare charging and routine. SilisoundTek lists magnetic charging and a charge time of about 1.5–2 hours, while sunvito lists magnetic charging and 2.5 hours. Those are useful planning details, but they do not settle overall convenience: your choice still depends on whether a bigger stored library and multi-device support matter more than sunvito’s simpler swim-training setup.
For swimming, I’d choose SilisoundTek IP68 because its 32GB MP3 storage gives me more room to prepare music offline, and it also lists Bluetooth 6.0 and multi-device support. I would not buy either model primarily as a webinar headset, since neither provides a stated microphone specification. For webinars, I’d look for a purpose-built call headset; for swim workouts, SilisoundTek is my pick.
