Best Swimming Bone Conduction Headphones for Calls

The best swimming bone conduction headphones for phone calls are the CXK X16, a 1.06 oz open-ear Bluetooth 6.0 headset with a built-in mic and IPX7 rating. If you want deeper submersion for lap swimming rather than poolside calls, the CXK X17 steps up to IPX8 with 12 hours of playback and drops call handling as its lead feature. Both are open-ear designs, which changes how a mic behaves in water and around it.

Best swimming bone conduction headphones for phone calls at a glance

How I cut the field down to five

I started with buyer profiles rather than a spec sheet. A swimmer who wants to take phone calls is really asking two things at once: can this headset survive the water I use it in, and does it have a mic that works when I'm dry between laps. Bluetooth does not travel through water, so anyone expecting live calls mid-stroke is going to be disappointed by every headset on the market. That framing shaped the cuts.

Three criteria did the screening work:

1. A stated waterproof rating of IPX7 or better, since anything lower is sweat-rated, not swim-rated.
2. A published battery figure, so I could compare training sessions honestly.
3. A named Bluetooth version, because pairing behaviour with a phone is what call quality rests on.

Listings that skipped any of those went out. What survived is five open-ear bone conduction models, all Bluetooth 6.0, four of them IPX8-rated, and one IPX7 pick that wins on weight and mic emphasis. The category path for all five is Headphones & Earbuds > Open-Ear Headphones.

Why phone calls are the awkward part of this category

Here's the trick with the phrase "swimming bone conduction headphones for phone calls": Bluetooth does not pass through water at any useful range, so no headset in this set makes calls while your head is submerged. What these products actually do is switch to an onboard MP3 mode underwater and hand back to Bluetooth when you surface. The best swimming bone conduction headphones for phone calls are therefore the ones with the clearest mic behaviour on land and the most reliable Bluetooth pairing between sets, not the ones with the deepest submersion claim.

That distinction matters because the marketing does not draw it. Four of the five listings mention swimming and calls in the same breath. Only the CXK X16 leads with a mic and open-ear call handling, and it pairs that with an IPX7 rating rather than IPX8, which tells you where the design priorities sit.

1. CXK X16 — Best overall

The X16 wins because it is the lightest headset here and the only one that leads on call handling rather than deep submersion.

Best for: poolside swimmers who take calls between sets Skip it if: you plan to fully submerge the headset

The X16 weighs 1.06 oz, ties with the CXK X17 for the lightest in this set, and is the only pick whose feature list names a mic in the product title. CXK says the wraparound frame uses flexible titanium and comes in at 28g. Bluetooth 6.0 handles pairing, and the listing claims 10 hours of playback per charge. The waterproof rating is IPX7, one step below the four IPX8 picks here, which means splashes and short immersion rather than lap-swimming depth.

Two things put it first for the call use case. The mic is the headline feature, not an afterthought bullet, and the weight makes it comfortable to wear through a workday between pool visits. The trade-off is honest: if you want to answer calls at the pool but train fully submerged, the X16 is not the deepest-rated pick here. It is the best swimming bone conduction headphones for phone calls when calls are the main event and the water is incidental.

Pros:

• Lightest published weight in the set at 1.06 oz
• Mic named in the product title
• Bluetooth 6.0 for phone pairing
• 10-hour playback claim
• One-year warranty

Cons:

• IPX7 rather than IPX8
• No stated submersion depth
• Only one seller lists it

2. CXK X17 Swimming — Best for beginners

The X17 is the beginner pick because it packages the longest CXK battery claim with an IPX8 rating and a swim-first design.

Best for: first-time buyers who want a longer battery and a swim-rated seal Skip it if: you want the lightest option in this set

The X17 shares the 1.06 oz weight of the X16, moves to an IPX8 rating with a triple-seal design that CXK says allows two-meter immersion, and pushes the playback claim to 12 hours. That extra runtime matters if you swim four or five times a week and hate charging cables. Bluetooth 6.0 handles land-side connections, and an onboard MP3 mode covers the underwater gap.

The transducer is the interesting differentiator. CXK lists a 15 by 10 mm bone conduction driver it calls PulseCraft, and describes it as delivering clearer audio than earlier CXK models. Treat that as a manufacturer claim rather than a measurement. What it does tell you is that the X17 is engineered around swimming first, calling second, which flips the priority order of the X16. Magnetic charging is included.

The trade-off is call emphasis. The X17 keeps its mic in a bullet point rather than the product title, and its IPX8 sealing is the kind of design that trades some acoustic transparency for water resistance. Fine for pool sessions, less optimised for a busy work-from-poolside routine.

Pros:

• IPX8 with a two-meter submersion claim
• 12-hour playback claim, the joint-longest here
• 1.06 oz weight, tied for lightest
• Magnetic charging
• Bluetooth 6.0 plus onboard MP3 mode

Cons:

• Highest price position of the two CXK picks
• Only one seller lists it
• Call handling not the lead feature

3. Fustaar Neckband — Best for heavy use

Fustaar earns the heavy-use slot because its neckband design keeps weight off your temples during long training blocks.

Best for: daily wearers who log long training sessions on land and in water Skip it if: you dislike a neckband sitting on your shoulders

The Fustaar is the outlier in shape. Instead of the wraparound frame the other four picks use, it hangs a lightweight neckband across the back of your neck and hooks over your ears. Fustaar lists the weight at 1.76 oz, the heaviest here, but that weight sits on your collarbone rather than your temples, which changes how it feels after two hours. IPX8 covers submersion and sweat, Bluetooth 6.0 handles pairing, and the playback claim is 10 hours. Magnetic charging is included, and the warranty is one year.

For a swimmer who also cycles, runs and takes work calls between sessions, the neckband trade is often worth it. Ear hooks stay put through movement without pressure on the jaw, and the neckband houses the battery and buttons where you can reach them without breaking stride. The best swimming bone conduction headphones for phone calls in a heavy-use context are usually the ones that stay comfortable across a full day, not the ones that shave grams.

The compromise is aesthetic and structural. A neckband is bulkier under a collared shirt than a wraparound frame, and the ear hooks add a step to putting the headset on. Fustaar also does not publish a submersion depth, only the IPX8 rating.

Pros:

• Neckband design shifts weight off the head
• IPX8 waterproof rating
• Bluetooth 6.0 pairing
• Magnetic charging
• 10-hour playback claim

Cons:

• Heaviest published weight in the set at 1.76 oz
• No published submersion depth
• Neckband less discreet than a wraparound frame

4. PSIER S18 — Best premium

The S18 takes the premium spot because it is the only pick here with two-device pairing named in its feature list.

Best for: swimmers who want two-meter submersion with multi-device pairing Skip it if: you need the longest single-charge runtime here

PSIER positions the S18 as the multi-device option. The feature list says users can connect two or more devices, which is the kind of small quality-of-life addition that matters when you swap between a phone for calls and a tablet for music. Bluetooth 6.0 handles both. The IPX8 rating comes with a stated two-meter submersion claim for up to one hour, and PSIER lists a 14 mm driver. Playback lands at eight hours per charge, the shortest published figure in this set.

The S18 sits at the top price position here, and it earns some of that with the second seller offer, which is worth noting only because every other pick has a single seller. What you are actually paying for is the pairing behaviour and the depth rating together. If you routinely take a call, then dive in for laps, then surface for another call, the S18's handoff between sources is the most useful feature in the group.

The weakness is battery. Eight hours is enough for four or five typical swim sessions, but the two CXK models and the ZOVIMAX all publish longer figures, and the runtime gap grows across a week of daily use. PSIER also does not publish a weight figure, which makes direct comfort comparisons harder.

Pros:

• Multi-device Bluetooth pairing
• IPX8 with two-meter submersion claim
• Two sellers listed
• One-year manufacturer warranty
• 14 mm driver

Cons:

• Shortest published battery claim at 8 hours
• Highest price position in this set
• No published weight figure

5. ZOVIMAX X7 MAX — Best for families

ZOVIMAX takes the family slot because it carries the deepest submersion claim and the longest warranty in this set.

Best for: households sharing one headset across pool and gym use Skip it if: you want a published weight figure before buying

The X7 MAX is the only pick here with a two-year warranty on the listing, which matters when a headset is being shared across a family and treated less carefully than an owner would treat their own. IPX8 covers submersion, and ZOVIMAX claims up to five meters for two and a half hours, the deepest figure in this set. Bluetooth 6.0 handles land-side audio, and MP3 mode covers underwater playback. The listing quotes 12 hours of playback in one bullet and 8 hours in another, so treat the runtime as somewhere in that band rather than as a fixed number. Full charge takes two hours over magnetic charging.

The 14.2 mm dynamic driver is the largest figure in this set, and ZOVIMAX pairs it with a bass-and-treble marketing claim. Attribute rather than believe: what you know for certain is the driver size and the submersion depth, both of which are useful reference points when a teenager takes it to the pool without asking.

Two gaps stop it from taking a higher slot. ZOVIMAX does not publish a weight, so you cannot line it up against the 1.06 oz CXK pair on comfort, and the runtime claims contradict each other within a single listing. For a family headset, neither is a dealbreaker; for a single serious user, both are reasons to consider the CXK X17 instead.

Pros:

• Two-year warranty, the longest here
• IPX8 with a five-meter submersion claim
• 14.2 mm driver, the largest listed
• Magnetic charging with a two-hour full charge
• Bluetooth 6.0 with MP3 mode

Cons:

• No published weight figure
• Contradictory playback claims on the listing
• Only one seller lists it

Waterproof ratings: what IPX7 and IPX8 actually mean here

The single most confusing part of buying swimming bone conduction headphones is the IPX code. Here is the practical version.

• IPX7 covers immersion in up to one meter of water for up to 30 minutes. That is the CXK X16. Fine for splashes, rain, sweat and the occasional dunk. Not designed for repeated lap swimming.
• IPX8 covers immersion deeper than one meter, but the exact depth and duration depend on what the manufacturer tests to. In this set, CXK says two meters for the X17, PSIER says two meters for one hour on the S18, and ZOVIMAX says five meters for two and a half hours on the X7 MAX. Fustaar publishes only the IPX8 rating without a depth.

The takeaway is that IPX8 is not one number. Read the stated depth and duration, and match it to your swimming style. The best swimming bone conduction headphones for phone calls at a shallow pool are not the same product as the best swimming bone conduction headphones for phone calls at open water, and the depth claim is the line between them.

How long does a charge really last on these?

Battery claims are the field where marketing runs furthest ahead of measurement. Here is what the listings publish for playback per charge:

• CXK X16: 10 hours
• CXK X17: 12 hours
• Fustaar: 10 hours
• PSIER S18: 8 hours
• ZOVIMAX X7 MAX: 8 to 12 hours, listed inconsistently

Real-world battery falls short of the claim when Bluetooth is streaming from a phone, when volume runs above the middle third, and when the headset is switching between MP3 mode and Bluetooth mode. Discount every figure by around 20 percent as a working estimate before you buy. Four of the five picks include magnetic charging, which is the small detail that decides whether a headset gets recharged after every swim or gets left in a gym bag until it dies.

Which pick suits which swimmer?

Match the pick to the pattern of use.

• You mostly take calls, and swimming is occasional: CXK X16. Lightest, mic-led, IPX7 is enough.
• You swim regularly and want the longest battery: CXK X17. Two-meter IPX8 and 12 hours.
• You cross-train hard, cycling and lifting as well as swimming: Fustaar. Neckband keeps the weight off your head.
• You juggle a phone and a tablet through the day: PSIER S18. Multi-device pairing is the differentiator.
• You share the headset in a household: ZOVIMAX X7 MAX. Longest warranty, deepest submersion claim.

Two natural cutoffs help decide fast. If you never fully submerge, the IPX7 X16 is the honest answer. If you always fully submerge, the IPX8 field opens up and battery becomes the tiebreaker.

The verdict

If your calls happen on land and your swimming is poolside and casual, the CXK X16 is the best swimming bone conduction headphones for phone calls in this set. It is 1.06 oz, it names the mic in its product title, it uses Bluetooth 6.0, and it publishes 10 hours of playback and a one-year warranty. The IPX7 rating is the trade you accept for a design that treats calls as the headline feature rather than a bullet.

If you swim laps and want more than splash resistance, flip to the CXK X17. Same weight, IPX8 with a two-meter submersion claim, 12 hours of playback, and the same Bluetooth 6.0 pairing. The cutoff between the two is how you actually use the water: if the headset ever goes underwater on purpose, take the X17.

The other three are situational winners. Fustaar suits a heavy cross-training week because of the neckband. PSIER earns its higher price position when you routinely switch between two paired sources. ZOVIMAX makes sense as a shared family headset, thanks to the two-year warranty and the five-meter depth claim.

FAQ

Can I take phone calls underwater with these headphones?

Take phone calls underwater is not something Bluetooth can support, because the signal does not travel through water at any useful range. Every pick in this set switches to onboard MP3 mode when submerged and reconnects to your phone by Bluetooth when you surface. The best swimming bone conduction headphones for phone calls handle calls on land and playback in water, not both at once.

Is the CXK X16 worth it over the cheaper alternatives?

The CXK X16 is worth it if your priority is calls with occasional swimming rather than lap training. It is the cheapest of the five and the lightest at 1.06 oz, and it is the only listing here that names the mic in its product title. If you want IPX8 submersion instead, the CXK X17 is a small step up in price for a two-meter depth claim.

What is the difference between IPX7 and IPX8 in this set?

The difference between IPX7 and IPX8 in this set is stated submersion depth. IPX7 covers one meter for up to 30 minutes, which is the X16. IPX8 covers deeper immersion, with CXK claiming two meters for the X17, PSIER claiming two meters for one hour, and ZOVIMAX claiming five meters for two and a half hours. Fustaar publishes IPX8 without a depth.

CXK X17 or PSIER S18 for a serious swimmer?

CXK X17 or PSIER S18 comes down to battery versus pairing. The X17 publishes 12 hours of playback on a single charge, four hours longer than the S18. The S18 offers multi-device Bluetooth pairing, which the X17 does not name. Serious swimmers who train daily should take the X17 for runtime. Swimmers who juggle a phone and tablet should take the S18.

What pitfall should I avoid when buying swimming bone conduction headphones?

The pitfall to avoid when buying swimming bone conduction headphones is assuming Bluetooth works underwater. It does not, on any product, from any brand. If a listing implies live streaming from your phone while submerged, it is misreading its own hardware. Look instead for an onboard MP3 mode, a stated IPX8 depth in meters, and a published Bluetooth version for surface use.

Start with the CXK X16 if you want the call-first design and the lightest frame in the set, and only step up to the X17 if your swimming is regular enough that IPX8 and 12-hour playback earn their extra outlay. The five picks here split cleanly by use pattern, so the decision is less about which is best in the abstract and more about which matches your week. Read the depth claim, discount the battery figure by around a fifth, and check the warranty before you commit. The X16 is the default answer for most callers who happen to swim.
