If you want open-ear headphones with up to 12 hours of listening, built-in music storage, and a titanium alloy frame, choose Wildhorn Outfitters Crank Bone Conduction; if you need lighting for night outings and an IP68 rating, choose Yistao Bone Conduction Headphones. For glasses wearers, the key distinction is whether you prefer Crank’s longer single-charge listening and stored music or Yistao’s lighter per-ear design and illuminated night-sports focus.
• Wildhorn Outfitters Crank Bone Conduction: Its standout combination is up to 12 hours of playback, Bluetooth 5.4, and built-in MP3 storage; the trade-off is magnetic charging rather than a charging case.
• Yistao Bone Conduction Headphones: Its standout features are dynamic RGB lighting, a charging case, and an IP68 rating; the trade-off is up to 7 hours of listening per charge, with only 3 hours in Aurora Mode.
• Crank suits listeners who want phone-free music storage, multipoint connectivity, and a titanium alloy frame with a silicone finish.
• Yistao suits runners and cyclists who want visible lighting, a compact per-ear fit, and case-supported listening between charges.
Crank is an open-ear bone conduction headset for people who want audio without sealing the ear canal. It sends sound through vibrations, leaving the outer ears unobstructed so natural sounds remain audible. That design can be useful on a run, during an outdoor workout, or while moving around a busy home. It is also worth considering for glasses wearers who find that sealed earbuds or bulky earcups compete with their frames.
The frame combines titanium alloy with a silicone-wrapped finish, and the listed materials include ABS, silicone, and titanium. Wildhorn describes the construction as lightweight, with the silicone intended to provide a softer contact against the cheekbones. For longer sessions, that focus on contact comfort may matter more than a fully enclosed listening experience. Bluetooth 5.4 supports wireless connections at up to 10 meters, and multipoint connectivity lets the headphones connect to multiple devices simultaneously. A built-in microphone supports hands-free calls, while voice assistant access and media controls offer ways to handle playback and calls without taking out a phone.
Crank’s most distinctive practical advantage is its built-in MP3 player. The product information says it can store over 2,500 songs, or up to 145 hours of audio files, which gives it a clear role for phone-free workouts. Battery life is listed as up to 12 hours of playback and up to 15 hours of talk time. A magnetic charging connector takes up to 2 hours for a full charge, with the listed quick-charge claim of 10 minutes for 1 hour of playback. Its IPX7 rating is described as suitable for sweat and heavy rain, with submersion specified up to 1 meter for 30 minutes. Skip Crank if you specifically want a charging case or built-in lights for night visibility.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Yistao’s open-ear design is aimed at people who want to keep their ears uncovered while listening, particularly during outdoor movement. Its most unusual feature is dynamic RGB lighting, intended to improve visibility on nighttime runs and rides. That gives it a different emphasis from Crank: rather than focusing on onboard music storage and multipoint connections, Yistao puts more attention on being seen in low-light conditions. The listed lighting brightness is 100 mcd, and the product notes that Aurora Mode reduces playback time to 3 hours.
The listed design uses silicone and an oval-shaped contact surface intended to follow the contour of the ear. Each earbud weighs less than 0.24 ounces, according to the product details. That per-ear weight may appeal to someone who wants a light-feeling alternative to larger headphones, including a glasses wearer comparing different kinds of head phones for glasses wearers. Yistao is listed as wireless, with no headphone jack and no noise-control feature.
Battery life is listed as up to 7 hours of continuous listening on one charge, with total playback reaching up to 30 hours when the charging case is included. That makes the case an important part of the overall listening plan: the single-charge figure is shorter than Crank’s, but the case adds recharging time away from a wall outlet. Yistao carries an IP68 rating for water and dust resistance, which is a stronger stated protection level than Crank’s IPX7 rating. The product information also lists an 18-month warranty. Skip Yistao if your priority is long playback from a single charge or storing music directly on the headphones.
• Best for longer playback between charges → Wildhorn Outfitters Crank Bone Conduction. It lists up to 12 hours of playback per charge, compared with Yistao’s up to 7 hours. - Best for a charging case → Yistao Bone Conduction Headphones. Its case contributes to a stated total of up to 30 hours of playback. - Best for phone-free workouts → Wildhorn Outfitters Crank Bone Conduction. Its built-in MP3 player can hold over 2,500 songs or up to 145 hours of audio files. - Best for visible nighttime use → Yistao Bone Conduction Headphones. Its dynamic RGB lighting is designed for low-light running and cycling, although Aurora Mode is listed at 3 hours of playback. - Best for multiple connected devices → Wildhorn Outfitters Crank Bone Conduction. Its listed multipoint connectivity supports simultaneous connections to multiple devices. - Best for the stronger stated water-and-dust rating → Yistao Bone Conduction Headphones. It is rated IP68; Crank is rated IPX7 and specifies submersion up to 1 meter for 30 minutes. - Best for a titanium alloy frame → Wildhorn Outfitters Crank Bone Conduction. Its frame is described as titanium alloy with a silicone-wrapped finish. - Best foldable headphone for glasses wearers → Neither can be confirmed as foldable. The provided specifications do not list a folding design, so I would not choose either on that basis alone.
For glasses wearers, start with the contact points rather than assuming that an open-ear design will automatically fit every frame. Neither data sheet gives a specific glasses-compatibility claim or describes exact clearance around the temples. Crank is described as resting against the cheekbones with a silicone-coated frame; Yistao emphasizes light earbuds and an oval contact surface. Those details offer useful clues, but they do not settle how either will feel alongside your own glasses.
Next, consider how you listen when away from a charger. Crank’s up-to-12-hour playback figure is for a single charge, and its built-in player makes it the more self-contained choice for a workout without a phone. Yistao’s up-to-30-hour figure includes the charging case, while listening on one charge is listed at up to 7 hours. If you regularly use lighting, remember that the listed Aurora Mode duration is shorter still, at 3 hours.
Water protection is another meaningful difference, but the ratings are not presented in identical terms. Crank is IPX7, with product information specifying submersion up to 1 meter for 30 minutes. Yistao lists IP68 and describes protection against water and dust. Choose based on the conditions and features that matter to you, and follow each product’s care guidance rather than treating either rating as a promise for every kind of water exposure.
Finally, think about charging and daily handling. Crank uses a magnetic charging connection and can be fully charged in up to 2 hours; Yistao comes with a charging case. If USB-C charging is a deciding requirement, neither sheet confirms it. For readers comparing options described as the best foldable headphone for glasses wearers, folding is also not confirmed for either model. Check the current price on Amazon using the page’s button, then weigh the included features against the way you actually plan to use the headphones.
I would choose Wildhorn Outfitters Crank Bone Conduction for the longer single-charge playback, built-in MP3 storage, and multipoint connectivity. Its open-ear design and silicone-coated frame also make it the more compelling spec-based option for glasses wearers who want to keep the outer ear uncovered, though fit will depend on the frames. I’d choose Yistao instead if RGB lighting, a charging case, and its IP68 rating matter more to my routine. For my glasses-wearer use case, Crank offers the more useful overall mix.
Neither product sheet guarantees compatibility with every style of glasses. Crank describes a silicone-coated frame that contacts the cheekbones, while Yistao highlights lightweight earbuds with an oval contact surface; the best fit will depend on how those contact points sit alongside your frames.
Crank lists up to 12 hours of playback on a charge. Yistao lists up to 7 hours on one charge, or up to 30 hours with the charging case included; Aurora Mode is listed at 3 hours.
Crank is rated IPX7 and is specified for submersion up to 1 meter for 30 minutes. Yistao is rated IP68 and described as water- and dust-resistant. Both data sheets describe outdoor or workout use, but use the products according to their care instructions.
The listed charging details do not confirm USB-C for either model. Crank uses a magnetic charging connector, while Yistao includes a charging case; check the product information for the exact charging arrangement before choosing if USB-C is essential.
