If you want a waterproof in-ear headphone that doubles as a normal Bluetooth headset for calls and noisy gym sessions, choose Sanpyl Swimming Headphones Underwater; if you need to swim laps with music and no phone nearby, choose INDIVISO Bone Conduction Headphones.
• Sanpyl Swimming Headphones Underwater — biggest strength: IPX8 waterproofing plus active noise reduction and voice prompts, in a light 55g silicone build.
• Sanpyl Swimming Headphones Underwater — biggest trade-off: it is a traditional Bluetooth in-ear set, so it relies on a paired phone and fits inside the ear canal rather than leaving it open.
• INDIVISO Bone Conduction Headphones — biggest strength: a built-in 32GB MP3 player that lets you swim with music without carrying a phone, plus a long-lasting 8-hour battery.
• INDIVISO Bone Conduction Headphones — biggest trade-off: bone conduction sends sound through vibration, so it does not seal out noise, and Bluetooth does not work underwater at all.
• Who each pick is for — Sanpyl suits pool-and-gym users who also want calls and quiet; INDIVISO suits open-water and lap swimmers who want phone-free music and awareness of their surroundings.
The Sanpyl Swimming Headphones Underwater is a silicone Bluetooth headset built around one clear idea: keep music going through sweat, splashes and pool water. It carries an IPX8 waterproof rating, which the brand describes as usable in the water without damage. That is a meaningful spec for anyone who has killed a normal pair of earbuds with a single dunk. The body is soft silicone and light — around 55g — and it ships with four earplugs in two silicone sizes, so you can fine-tune the seal to your own ears.
What it does best is bridge two worlds. Because it is a Bluetooth 5.0 headset with noise reduction, it works as an everyday pair too: you can take a call in a busy gym and the noise-cancelling is meant to keep voices clear against background racket. The intelligent voice prompts are a genuinely useful touch for swimmers — power on, pairing status, connection, incoming call alerts and low-battery shutdown are announced, so you are not blindly guessing what the headset is doing while your hands are wet. The "shark fin" stabiliser rotates along the ear contour to lock the fit, which matters when you are mid-stroke, mid-sprint or on a bike.
Who should buy it: swimmers and multi-sport users who want one headset for the pool, the run and the commute, and who value call quality and noise isolation. The two earplug sizes also help if standard tips never sit right for you.
INDIVISO Bone Conduction Headphones: Who It's For
The INDIVISO Bone Conduction Headphones is the more specialised swimmer's tool, and the 32GB MP3 mode is the reason. With that much built-in storage — enough for roughly 9,000 songs — you load your music once and then swim with no phone at all. The brand is explicit that you should switch to MP3 mode when swimming, because Bluetooth cannot transmit underwater. That one design decision is what separates a headset that tolerates water from one that is actually built for it.
The open-ear bone conduction design is the second half of the story. Instead of sealing your ear canal, it sends sound through cheekbone vibration, which keeps your ear canal clean and, crucially, keeps you aware of what is happening around you. For outdoor swimmers, runners on shared paths and cyclists in traffic, that awareness is a real safety feature, not a marketing line. The IPX8 rating here is described as withstanding immersion up to 3 metres for extended periods, which covers lap swimming, surfing and heavy rain.
Battery life is the other standout: a 200mAh battery rated for 8 hours of music or talk and 72 hours of standby, charging in about 2 hours through a magnetic waterproof port. If you swim several times a week, that is a headset you charge once and forget. Bluetooth 5.4 is on board for dry-land use, with a range around 10 metres and the ability to pair two devices at once so you can hop between a phone and a laptop.
Who should buy it: lap swimmers, open-water swimmers, surfers and triathletes who want music without a phone, and anyone who prioritises hearing their surroundings. Who should skip it: people who mainly want a noise-isolating headset for calls in loud places. Bone conduction deliberately lets outside sound in, so a noisy gym or a windy commute will compete with your audio. It is also the heavier of the two at 4.8 ounces, and the open-ear hook shape is a different feel from a snug in-ear fit.
Side-by-Side: Which Should You Choose?
• Best for swimming without a phone → INDIVISO Bone Conduction Headphones. The 32GB MP3 mode exists precisely for underwater listening where Bluetooth fails.
• Best for staying aware of your surroundings → INDIVISO. Open-ear bone conduction leaves your ear canal unobstructed.
• Best for battery life → INDIVISO. 8 hours of playtime and 72 hours standby from a 200mAh battery, versus the Sanpyl's 180mAh cell with no rated runtime given.
• Best for the lightest feel → Sanpyl. Around 55g in soft silicone, versus 4.8 ounces for the INDIVISO.
• Best for multi-device switching → INDIVISO. Bluetooth 5.4 supports two simultaneous connections; Sanpyl uses Bluetooth 5.0.
• Best for fit security in the pool → either. Sanpyl uses rotating shark-fin stabilisers; INDIVISO uses an ergonomic open-ear hook.
• Best for a mixed pool-and-commute routine → Sanpyl. It behaves like an ordinary Bluetooth headset the moment you leave the water.
In my opinion, the INDIVISO Bone Conduction Headphones is the better buy for anyone whose main goal is swimming. The 32GB MP3 mode solves the one problem every Bluetooth swimmer hits — no signal underwater — and the 8-hour battery, IPX8 immersion rating and open-ear awareness make it a genuinely purpose-built swim headset. I would pick the Sanpyl Swimming Headphones Underwater instead if you want a single pair for the pool, the gym and phone calls, and you value noise reduction and a light in-ear fit over phone-free swimming. Both are IPX8, so the water itself is not the deciding factor; what you want to hear while you are in it is.
are headphones waterproof
Not all of them. Waterproofing is a rating, not a category. Both products here carry an IPX8 rating, which the brands describe as protecting against water immersion — the Sanpyl for use in water without damage, the INDIVISO for immersion up to 3 metres for extended periods. A headset without a stated water-resistance rating should not be assumed safe for swimming.
are headphones water resistant
Water resistant and waterproof are different levels. Water resistance usually means the product tolerates splashes, sweat and rain, while an IPX8 waterproof rating is designed for actual immersion. If your plan is to swim laps, look for an explicit IPX8 claim like the two headsets compared here, and remember that even IPX8 models like the INDIVISO require MP3 mode underwater because Bluetooth signals do not travel through water.
Can I use the INDIVISO headset with Bluetooth while swimming?
Yes, for music and calls. The Sanpyl Swimming Headphones Underwater is a Bluetooth 5.0 headset, so it needs a paired device within range. If you want to swim without a phone, the INDIVISO's built-in 32GB MP3 storage is the feature that matters. For current pricing on either, check the latest price on Amazon.
