For phone calls, bone conduction earbuds for phone calls are best in my opinion from TECKNET, thanks to its built-in noise-reduction microphones and 10-hour battery.
Choose CXK instead if you want a lighter 28g frame and Bluetooth 6.0 for everyday calls and workouts.

bone conduction earbuds for phone calls at a Glance
• Opinta Swimming Headphones — best for calls alongside swim training; pick this if built-in MP3 storage and IPX8 waterproofing matter as much as Bluetooth calling.
• CXK Bone Conduction Headphones — best for lightweight everyday calls; pick this if you want a 28g open-ear frame and up to 10 hours of use.
• TECKNET Bone Conduction Headphones — best for calls during workouts and commutes; pick this if its built-in noise-reduction microphones and 10-hour battery fit your routine.
• PSIER Bone Conduction Headphones — best for long outdoor sessions; pick this if a 23g frame, adjustable strap, and up to 10 hours of listening appeal.
Opinta is the swimming-focused option here, but it also supports Bluetooth and calls when you’re out of the water. Its open-ear bone-conduction design leaves the ear canals uncovered, and the product is listed at 30g. That makes it a practical fit for someone who wants one headset for pool workouts, running, cycling, and occasional phone conversations.
The standout is its two-mode setup. Bluetooth 5.4 handles wireless listening and calls on land, while 32GB of built-in memory stores audio for MP3 playback. Bluetooth does not work underwater, so you need to switch to MP3 mode before swimming. The IPX8 rating is intended for underwater use, with the listed guidance allowing submersion to 3 metres. That separation between phone-linked listening on land and stored audio in the pool is central to the buying decision.
For calls and training, the listed battery life is up to eight hours of playback or talk time, with a two-hour charge. Multifunction buttons handle basic playback and call answering or ending. The set also includes an adjustment strap, which may help if the open frame feels loose during movement. The brand says the magnetic charging port should be dry before charging, a useful routine to remember after a swim.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The trade-off is that Opinta has the shortest stated battery life among these four, and its swimming capability does not mean you can take Bluetooth calls underwater. I’d choose it if swimming is a real part of your routine and stored MP3 playback is useful; for a call-first headset that stays on land, the other options offer longer listed use between charges.
CXK’s X14 is a straightforward open-ear headset for people who want calls and audio without covering their ears. It weighs 28g and uses a wraparound titanium frame with silicone contact points. That combination is aimed at a secure fit for workouts and extended wear, while the open design lets you remain aware of nearby sounds.
Bluetooth 6.0 provides the wireless connection to a phone, and the headset has a built-in microphone for calls. A one-key control is described for handling music and calls. The listed battery life is up to 10 hours, and a full charge takes about two hours over USB-C. For a workday that includes a few calls and a walk or gym session, those figures suggest fewer charging interruptions than Opinta’s eight-hour claim.
CXK also lists 15mm bone-conduction drivers and an enclosed-cavity design. Those details describe its audio approach, but they do not establish how your caller’s voice will sound in every setting. The product materials describe the microphone as supporting clear calls, but do not specify a noise-reduction microphone feature. If call quality in busy places is your priority, TECKNET makes a more explicit microphone claim.
CXK is not suitable for swimming. Its IPX6 waterproof rating is described for workout use, not underwater listening. I’d pick it for a light, open-ear headset that can shift between calls and exercise, particularly if you do not need swim-ready hardware or a dedicated water-use mode.
TECKNET is my call-focused choice of this group because it specifically lists a built-in noise-reduction microphone, alongside up to 10 hours of battery life. It uses an open-ear design and a wraparound titanium-alloy frame, with a listed weight of 27g. That makes it a sensible candidate for someone who wants to take calls while walking, commuting, or working at a desk without sealing off the ears.
Bluetooth 6.0 supports wireless connection to compatible devices, and the product information describes use with phones, tablets, and laptops. The included adjustable strap is intended to help customize the fit. For calls and everyday listening, the main practical draw is the combination of a built-in microphone, physical button controls, and a battery claim that matches a full day of mixed use for many routines—though actual runtime depends on use.
Its IPX5 rating is for resistance to sweat and moisture such as rain, not for swimming. The stated charging time is about two hours over USB-C. TECKNET lists 16mm drivers, but driver size alone is not a reliable way to predict call clarity; the noise-reduction microphone is the more relevant listed feature for people who expect to speak in settings with background sound.
PSIER Bone Conduction Headphones
PSIER puts lightweight fit and long listening sessions at the center of its design. The headset weighs 23g and uses a flexible memory-titanium frame, with an adjustable strap included. For runners, cyclists, and hikers who want an open-ear fit, that low listed weight and ability to adjust the frame are meaningful advantages. The headset has a built-in microphone and Bluetooth 6.0 for calls and wireless audio.
The battery is rated for up to 10 hours of music or podcast playback at 50% volume, with a full charge taking about two hours over USB-C. That volume condition matters: the stated figure is tied to a particular listening level, so it should not be treated as a guarantee of 10 hours in every call-and-audio routine. The product also lists 13mm bone-conduction drivers and app-based EQ options for adjusting the sound.
PSIER’s IPX5 rating is intended for sweat and rain, and the product is explicitly not suitable for underwater use. Its open-ear layout helps keep the ear canals uncovered, but it will not isolate you from your surroundings. For outdoor exercise, that can be a useful design choice; for calls in a noisy space, it is worth considering how much ambient sound you are comfortable hearing.
The trade-off is that its microphone description is less specific than TECKNET’s: PSIER lists a mic, but does not make the same explicit noise-reduction claim. I’d choose PSIER if a very light frame and adjustable fit are the priorities, and you want a long-session headset for outdoor movement that can also handle calls.
I compared the published specifications and features that matter to calls, including microphone details, battery claims, fit, connectivity, and water resistance.
The ranking reflects my independent editorial opinion based on those differences.
No brand paid for placement.
Are bone-conduction headphones suitable for phone calls?
They can be, provided the model includes a microphone and connects to your phone over Bluetooth. Among these options, TECKNET specifically lists a built-in noise-reduction microphone; CXK, PSIER, and Opinta also list microphones or call support.
No. The product information says Bluetooth is not supported underwater. Switch to MP3 mode before swimming and use the built-in memory for stored audio.
CXK, TECKNET, and PSIER each list up to 10 hours, while Opinta lists up to eight hours of playback or talk time. PSIER’s 10-hour playback figure is specified at 50% volume.
For phone calls, I recommend TECKNET if you want an open-ear headset with a specifically described noise-reduction microphone and up to 10 hours of use. If you’re comparing under 20 earbuds, these bone-conduction models are a different category: choose by fit, call features, and whether you need swim-ready playback, not by form factor alone.
