Best Bone Conduction Headphones for Tight Budgets

The best budget waterproof bone conduction headphones are the CXK X16, which pair an IPX7 claim with a 1.06 oz body and a stated 10 hours of playtime while sitting cheapest of the five here. If you actually swim laps rather than sweat, the PSIER S18 and its IPX8 two-metre claim is the better buy. This is not a category for audiophiles, and it never has been. Anyone chasing deep bass or isolation on a plane should stay with sealed earbuds instead, because open-ear designs leak sound by design and leave your ear canal wide open to ambient noise. What they give you back is awareness, and a housing that shrugs off water.

Best budget waterproof bone conduction headphones at a glance

How I screened these five and who each one suits

I started with the buyer, not the spec sheet. Five sets, five different training patterns.

The runner who sweats through a shirt needs a sealed housing and a body light enough to forget. That is the CXK X16 at 1.06 oz. The commuter who takes calls at a desk and lifts three times a week needs a microphone and a comfortable frame more than a submersion depth, which is the Gelecek HS1. The lap swimmer needs onboard storage, because Bluetooth does not travel through water, and that narrows things to the CXK X17 and the PSIER S18, both of which list an MP3 mode alongside Bluetooth 6.0.

Then there is the household that shares one set. The X17 fits that job because it publishes the longest playtime claim here at 12 hours and covers both pool and pavement.

Last, the cyclist. Road riding rewards a set that stays planted over rough tarmac, and the Fustaar X13 is the heaviest of the five at 1.76 oz, which reads as more material in the band.

What got cut in each case was anything that only did one of those jobs while asking the price of a set that does two.

IPX5, IPX7, IPX8: what do these ratings actually cover?

The IP water code is the single number that separates these five, and most shoppers read it as a sliding scale of "more waterproof". It is not. Each step describes a different test.

• IPX5 covers a low-pressure water jet from any direction. Sweat and light rain, yes. Immersion, no. The Gelecek HS1 carries this claim.
• IPX7 covers immersion in one metre of water for 30 minutes. That is a dropped-in-the-sink rating. The CXK X16 claims it.
• IPX8 covers immersion deeper than one metre, with the manufacturer stating the depth and duration. CXK says the X17 handles two metres. PSIER states two metres for one hour on the S18. Fustaar claims IPX8 on the X13 without publishing a depth in its bullets.

That last point matters more than the digit. IPX8 is the only rating in the series where the number alone tells you nothing, because the standard leaves the depth to the maker. Two listings here spell it out and one does not.

None of these figures is an independent measurement I can verify. They are what each brand publishes, and a claim is not a certificate.

1. CXK Bone Conduction Headphones Bluetooth 6.0 Open Ear — Best overall

The lightest body here at 1.06 oz, the cheapest of the five, and an IPX7 claim that covers everything short of the pool.

Best for: runners and gym users who sweat hard and train in rain Skip it if: you swim laps and want submersion depth

Two things separate the X16 within this set. It is the cheapest, and it ties for the lightest at 1.06 oz. Weight is the specification that decides comfort in bone conduction, because the transducers have to press against your cheekbones to work, and a heavier band presses harder over an hour. CXK also describes a flexible titanium frame in a 28g wraparound design, which is the same construction language the Gelecek pick uses.

The water claim is IPX7, sitting between the IPX5 of the Gelecek and the IPX8 of the three swim-focused picks. For sweat, rain and a rinse under the tap, IPX7 is more headroom than a runner will ever use. CXK lists Bluetooth 6.0, a stated 10 hours of playtime, a microphone and a companion app with custom EQ. It also sells faster than anything else here, which tells you shoppers keep landing on it.

The trade-off is straightforward. No MP3 mode, so it cannot follow you underwater the way the X17 and S18 claim to, and no listed submersion depth. You are buying the everyday set, not the pool set.

Pros:

• Cheapest of the five picks here
• Ties for lightest at 1.06 oz
• IPX7 immersion claim, above sweat-only ratings
• Bluetooth 6.0 with microphone and app EQ
• The set buyers choose most often here

Cons:

• No MP3 storage mode for swimming
• IPX7 sits below the two-metre claims of three rivals
• Only one seller lists it
• One published colour, matte black

2. Gelecek New Bone Conduction Open-Ear Headphones — Most versatile

The second-cheapest set here, with a titanium frame and a 10-hour claim, held back by the weakest water rating of the five.

Best for: commuters who want one set for calls and light workouts Skip it if: your sessions involve heavy sweat or downpours

The HS1 is the generalist. Gelecek lists a titanium frame at 29 grams, a claimed 10 hours of battery, a microphone, and cheekbone transmission that keeps your ears open to traffic and gym announcements. It is the second-cheapest of the five, which makes it the natural pick when the set has to cover a commute, a phone call and a treadmill rather than one specialist job.

Two things in the listing deserve a closer read. The water claim is IPX5, the lowest here, which covers a water jet but not immersion. And the connectivity bullets disagree with themselves: the title and one bullet say Bluetooth 6.0, while another bullet says Bluetooth 5.4. When a listing contradicts itself on a core spec, treat the lower figure as the safe assumption.

The other gap is weight. Gelecek publishes 29 grams inside a feature bullet but no weight figure in the specification block, so there is nothing standardised to line up against the 1.06 oz of the two CXK sets.

Against the rest of this set, the HS1 trades water protection for price. That is a fair swap if you train indoors and dry.

Pros:

• Second-cheapest pick in this comparison
• Titanium frame, claimed at 29 grams
• 10-hour playtime claim matches pricier picks
• Microphone for calls and meetings

Cons:

• IPX5 is the weakest water claim of the five
• Listing contradicts itself on Bluetooth version
• No weight in the published specifications
• No MP3 mode, so no swimming use

3. CXK Bone Conduction Headphones IPX8 Waterproof Swimming — Best for families

The longest playtime claim here at 12 hours, plus an IPX8 two-metre rating and MP3 storage, in the same 1.06 oz body as the winner.

Best for: a household sharing one set between pool and pavement Skip it if: you only ever train dry and want the lowest outlay

The X17 is the X16's swim-capable sibling, and the specification sheet shows the family resemblance: same 1.06 oz weight, same one-year warranty entry, same Bluetooth 6.0. What changes is the water engineering and the storage. CXK claims IPX8 with a triple-seal design rated to two metres, and adds an MP3 mode so the set plays without a phone in range.

The playtime claim is the longest of the five at 12 hours, and CXK lists magnetic charging. That combination is what makes it the household pick. One set covers a swimmer, a runner and a dog walker, and 12 hours means it survives a week of short sessions without anyone hunting for the cable. CXK also names the driver: a 15 x 10 mm PulseCraft bone conduction transducer, the only dimensional driver figure in this comparison other than the PSIER's 14 mm.

It costs more than the X16 and the Gelecek, and it sits in the most expensive tier here alongside the PSIER. It also sells more slowly than either entry pick, so it is the less-travelled choice. If nobody in the house swims, that extra outlay buys sealing you will never use.

Pros:

• Longest playtime claim of the five at 12 hours
• IPX8 claim with stated two-metre depth
• MP3 mode plus Bluetooth 6.0
• Ties for lightest at 1.06 oz
• Magnetic charging listed

Cons:

• Priced in the top tier of this set
• Sells more slowly than both entry picks
• Only one seller lists it
• No stated immersion duration alongside the depth

4. PSIER Bone Conduction Headphones — Best premium

The only listing here that publishes both depth and duration, two metres for one hour, and the only one with a warranty term spelled out in words.

Best for: swimmers who load tracks on and leave the phone behind Skip it if: you need long unbroken listening between charges

The S18 is the most expensive pick here, and the reason to pay it is precision in the claim. PSIER states IPX8 certification with submersion to two metres for one hour. Every other IPX8 listing in this set gives a depth or nothing at all. Duration is the half of the rating that decides whether a set survives a full swim session rather than a quick dip, so having it in print is worth something.

PSIER lists a 14 mm driver, Bluetooth 6.0 with low latency, multi-device connection, and an MP3 download mode for phone-free swimming. The warranty entry reads "1 year manufacture", the only one of the five written as an actual term instead of a bare digit. It is also the only pick with more than one seller listing it.

The cost is battery. PSIER claims 8 hours in Bluetooth mode, the shortest figure in this comparison and four hours behind the CXK X17. There is also no weight in the specifications, which leaves you guessing how it compares against the 1.06 oz sets, and that matters on a long swim.

Pros:

• Only listing with both depth and duration stated
• 14 mm driver named in the specifications
• MP3 mode plus multi-device Bluetooth 6.0
• Warranty written out as one year manufacturer
• Several sellers stock it

Cons:

• Shortest playtime claim here at 8 hours
• Most expensive pick in this comparison
• No published weight figure
• No colour options beyond matte black

5. Fustaar Open Ear Bone Conduction Headphones — Best upgrade

A heavier 1.76 oz neckband with an IPX8 claim and magnetic charging, aimed at riders who want the band to stay put.

Best for: cyclists who want a heavier, more planted neckband Skip it if: weight on your neck bothers you on long sessions

The X13 is the outlier on weight. At 1.76 oz it is roughly two-thirds heavier than the two CXK sets, and Fustaar frames that as a feature: a neckband with a secure ear-hook design meant to stay in place during movement. On a bike over broken tarmac, a band that does not shift is worth more than a band that disappears. That is the case for this pick, and it is a narrow one.

Fustaar lists Bluetooth 6.0, a claimed 10 hours of playtime, magnetic charging, and IPX8 waterproofing described as protection from sweat, rain and intense workouts. Read that bullet closely. It claims the top water rating but describes sweat resistance, and it never publishes a submersion depth. Since IPX8 has no meaning without a stated depth, treat this one as a sweat-and-rain set rather than a swimming set.

Price-wise it lands in the middle of these five, above both entry picks and below the two premium sets. It is also the slowest seller of the group. Against the CXK X16 it asks for more money and more weight, and the only clear thing it adds is the neckband's planted feel.

Pros:

• Heaviest, most planted band at 1.76 oz
• 10-hour playtime claim with magnetic charging
• Bluetooth 6.0 for calls and meetings
• Mid-tier price, below both premium picks

Cons:

• IPX8 claimed with no stated depth or duration
• Heaviest set here by a wide margin
• No MP3 mode despite the water claim
• Slowest seller of the five

Does budget waterproofing survive a real pool session?

Here's the trick with cheap water ratings: the rating describes the housing, not the radio. Bluetooth 2.4 GHz signal barely travels through water, so a set can be perfectly sealed and still go silent the moment your head goes under and your phone stays on the deck.

That is why MP3 mode, not the IP number, is the real deciding feature for swimmers. Two picks here list it: the CXK X17 and the PSIER S18. The other three do not, which means their water ratings protect them in the shower and the rain but cannot make them useful in a lane.

The second thing to know is that these numbers describe fresh water. Chlorine and salt are chemical exposure, not immersion, and no listing in this set says anything about either. Rinsing after every swim is the habit that keeps a sealed set sealed.

Third, magnetic charging contacts. The CXK X17 and the Fustaar X13 both list magnetic charging, which removes the port a budget set usually leaks through. Worth noting when the alternative is a rubber flap.

What the listings leave out

Even the more detailed listings here go quiet on several things a buyer would want.

1. Battery specifics. Every playtime claim is a single number with no volume level attached. A 10-hour figure at low volume and a 10-hour figure at gym volume are different products.
2. MP3 storage capacity. Both swim-capable picks list an MP3 mode. Neither publishes how many gigabytes it holds, so plan on loading a playlist, not a library.
3. Charge time. Not one of the five states how long a full charge takes. Magnetic contacts are described as fast on two picks, without a figure.
4. Warranty terms. Three listings show a bare "1" in the warranty field. Only the PSIER spells out one year manufacturer. A digit without a unit is not a term you can rely on.
5. Fit adjustment. Two picks say "one size", none publishes a band length. Bone conduction depends on transducer placement on the cheekbone, and head width decides that.

None of these gaps is unusual at this end of the market. They are the reason I weight published specifications over feature copy when I compare budget waterproof bone conduction headphones, because a figure in a specification block is at least a figure.

When a different pick wins

The winner is the default, not the answer for everyone. Three conditions flip it.

• You swim laps at least once a week. Skip the X16 entirely. Its IPX7 claim covers immersion but it has no MP3 mode, so the music stops when your phone does not follow you in. Go to the CXK X17 for 12 hours of claimed playtime, or the PSIER S18 for the only stated one-hour duration at two metres.
• You ride a road bike. Movement over rough surfaces is where a light band shifts. The Fustaar X13 at 1.76 oz is the heaviest here and Fustaar builds its pitch around staying planted. Accept the neck weight and you get stability.
• Your budget is the hard constraint and you train indoors. The Gelecek HS1 is second-cheapest and claims the same 10 hours as picks costing more. IPX5 handles gym sweat. It does not handle a downpour, so this only works if your training stays under a roof.

One more threshold worth naming. If a published submersion depth matters to you, three of these five claim IPX8 but only two say how deep, and only one says for how long.

The verdict

If you sweat and run and want the lightest possible band, the CXK X16 is the pick. It is the cheapest of these five, ties for lightest at 1.06 oz, claims IPX7 immersion, and lists 10 hours of playtime with Bluetooth 6.0 and app EQ. It also sells faster than anything else in this group, which is a reasonable signal in a category full of near-identical listings.

If you swim, the PSIER S18 is the pick. It is the only listing here that states both submersion depth and duration, two metres for one hour, and the only one whose warranty reads as an actual one-year manufacturer term rather than a bare digit. It lists a 14 mm driver, multi-device pairing and an MP3 mode that keeps playing when your phone stays poolside.

The cutoff is whether your head goes underwater. Above the waterline, buy on weight and price, and the X16 wins both. Below it, buy on stated depth plus onboard storage, and the S18 is the only pick that publishes both halves of the claim.

The CXK X17 sits between them as the household compromise, with the longest playtime claim of the five at 12 hours and an IPX8 two-metre rating in the same 1.06 oz body as the winner.

FAQ

Are budget waterproof bone conduction headphones worth it compared with sealed earbuds?

Budget waterproof bone conduction headphones are worth it when awareness matters more than sound isolation. Open-ear designs leave your ear canal clear, so you hear traffic, a coach or a pool deck announcement. The trade is bass and isolation, which sealed earbuds do better. If you run on roads or share a gym floor, the awareness is the whole point.

What does IPX8 actually mean on these headphones?

IPX8 actually means immersion deeper than one metre, with the manufacturer stating the depth. That is why the number alone is not enough. PSIER publishes two metres for one hour on the S18, CXK publishes two metres on the X17, and Fustaar claims IPX8 on the X13 without a depth. Look for the depth figure, not the digit.

CXK X16 or PSIER S18: which should I buy?

The CXK X16 or PSIER S18 question comes down to water. Choose the X16 if you sweat, run and train in rain: it is the cheapest here, weighs 1.06 oz, and claims IPX7 with 10 hours. Choose the S18 if you swim, because it lists MP3 mode plus two metres for one hour, though playtime drops to a claimed 8 hours.

Will these work with my phone and a tablet at the same time?

They work with two devices only on the PSIER S18, which is the one listing here describing multi-device connection alongside Bluetooth 6.0. The other four list Bluetooth pairing without a multipoint claim, so plan on one connection at a time. The Gelecek HS1 listing is inconsistent, naming both Bluetooth 6.0 and 5.4 in different bullets.

What is the most common mistake buying budget bone conduction headphones?

The most common mistake buying budget bone conduction headphones is treating the water rating as swim readiness. Bluetooth signal does not pass through water, so a sealed set with no onboard MP3 storage falls silent underwater. Only the CXK X17 and the PSIER S18 here list an MP3 mode. Check for storage before you check the IP number.

Start with your training, not the spec sheet. Write down whether your head goes underwater, then pick from the two picks that publish both a depth and an MP3 mode, or from the three that do not and cost less. The CXK X16 earns the default slot because it removes the two things that make cheap open-ear sets annoying: excess weight on the cheekbones and a water rating that panics in the rain. It is 1.06 oz, it claims IPX7, and it sits at the bottom of this price range. For most runners, that is the whole decision.
