• AIAUXAI Over Ear Earbuds — biggest strength: a 3.5mm wired connection with ear hooks and a right-angle plug that works with almost anything that has a headphone jack, no pairing or charging required.
• AIAUXAI Over Ear Earbuds — biggest trade-off: no Bluetooth and no battery, so you're physically tethered to your device by a 5.9ft cord.
• CALOETHNEY Headphones Retractable — biggest strength: Bluetooth 5.1 with a 200mAh battery rated for up to 22 hours of playback, dual-device pairing and retractable earbuds that store themselves in the neckband.
• CALOETHNEY Headphones Retractable — biggest trade-off: it's wireless only, so it's useless on a device with no Bluetooth, and it needs a 2-hour charge to run.
• Who each is for: AIAUXAI suits students, Chromebook/laptop users and anyone who wants zero fuss; CALOETHNEY suits commuters, callers and gym-goers who want freedom from wires.
The AIAUXAI Over Ear Earbuds are built around one idea: plug in and go. There's a 3.5mm jack, a right-angle connector, a 5.9ft cord and a set of ear hooks that wrap around the ear. That combination is aimed squarely at people whose devices still have a headphone jack — Chromebooks, older iPads, Kindles, laptops, MP3 players and a long list of Samsung Galaxy and other Android phones. The dynamic driver covers a 20Hz–20,000Hz range, and the inline remote gives you button-based volume control, so you can adjust without reaching for your phone.
In my opinion, the ear-hook design is the real story here. It's what makes these a genuine sport option: the hooks hold the buds in place instead of relying purely on the tip sealing inside your ear. If you've ever had earbuds slip out mid-run or mid-set, that's the problem this shape is trying to solve. The description also points to a comfortable fit over long sessions, and the set ships with two pairs of eartips and a carrying case, so you can dial in the seal.
Who should buy it? Anyone who wants the simplest possible audio setup. Students on a school Chromebook, commuters with an older phone, people who are tired of charging yet another gadget — this is the low-maintenance pick. It also works for hands-free calls through the inline mic, and the wired connection means zero latency, which matters if you're watching video or gaming.
Who should skip it? If your phone or tablet has no headphone jack, this isn't for you — you'd need an adapter, and that defeats the point. Skip it too if you want to move around the room untethered, or if you want active noise cancellation, which a passive wired earbud simply doesn't offer. And note the age guidance: it's listed for over 7 years old, which is worth knowing if you're buying for a younger child.
The CALOETHNEY Headphones Retractable is a neckband headset that does a lot more than its name suggests. It runs Bluetooth 5.1 with a stated range of up to 10 meters (the bullet points claim up to 15m/48ft), and the standout trick is dual connectivity: it can hold two devices at once and switch between them. In practice that means your laptop and your phone can both be connected, and you jump between a call and your music without re-pairing. The 200mAh battery is rated at up to 22 hours of music playback, 20 hours of talk time and 550 hours of standby, with a 2-hour charge time and on-device battery level readout.
The retractable design is what separates it from a standard neckband. You pull the earbud wires out to whatever length you want, then press the retract button and they coil back into the band. That's a genuinely useful detail for anyone who's spent time untangling a cord in a bag or pocket. The band itself is silicone, described as ergonomic for long wear, and the whole thing carries an IPX5 sweatproof rating — so it's aimed at fitness, running and sweaty sessions, not just desk work.
Call handling gets real attention too. There's a built-in mic with noise-cancellation (CVC6.8 is named), and the headset vibrates on an incoming call so you feel it even in a noisy environment. Easy-click buttons let you answer, end, reject and redial. Audio is handled by a dynamic driver with a 20Hz–20,000Hz range, and the spec sheet lists active noise cancellation as a control feature.
Who should buy it? Commuters, people who take a lot of calls, and gym-goers who want wireless freedom with a secure neckband fit. If you constantly juggle two devices, the dual-connection feature alone is a strong reason. Who should skip it? Anyone whose main device has no Bluetooth, and anyone who dislikes things around their neck — this is a neckband, not a true wireless bud, and that's a fit preference you have to be comfortable with. It's also listed as adult-oriented, with a 1-year warranty.
• Best for battery life → CALOETHNEY Headphones Retractable. Up to 22 hours of playback on a 200mAh battery, versus no battery at all on the wired AIAUXAI.
• Best for zero-hassle, always-ready use → AIAUXAI Over Ear Earbuds. No charging, no pairing, no pairing errors — plug into the 3.5mm jack and it works.
• Best for calls → CALOETHNEY Headphones Retractable. Inline noise-cancelling mic, vibration alerts and one-touch answer/reject/redial give it the edge for phone use.
• Best for sweaty workouts → CALOETHNEY Headphones Retractable. IPX5 sweatproof plus a secure neckband; the AIAUXAI counters with ear hooks, which also hold well but aren't rated for water resistance.
• Best for old or non-Bluetooth devices → AIAUXAI Over Ear Earbuds. Chromebooks, older iPads, Kindles, MP3 players and jack-equipped phones are all covered.
• Best for switching between two devices → CALOETHNEY Headphones Retractable. Simultaneous dual-device connection is something the wired AIAUXAI simply can't do.
• Best for tangle-free storage → CALOETHNEY Headphones Retractable. The retractable earbuds coil back into the band instead of dangling.
• Best for lowest-latency audio → AIAUXAI Over Ear Earbuds. A wired connection avoids Bluetooth audio delay, which helps for video and gaming.
If I had to pick one, I'd buy the CALOETHNEY Headphones Retractable — but only because my day is mostly wireless. In my opinion, its combination of up to 22 hours of battery, dual-device pairing, a vibration call alert and retractable earbuds covers the most everyday situations for the widest range of people, and the IPX5 rating makes it a genuine gym option. That said, I'd recommend the AIAUXAI Over Ear Earbuds without hesitation to anyone who lives on a Chromebook, an older phone or any device with a headphone jack — for that person, the wired connection is a feature, not a limitation. Decide based on whether your main device has Bluetooth, and the choice makes itself.
Both can work. The CALOETHNEY has an IPX5 sweatproof rating and a neckband that stays put, which suits heavy sweating. The AIAUXAI relies on ear hooks to stay in place and isn't rated for water resistance, so it's better for lighter workouts or indoor training.
Only if that device has Bluetooth. The CALOETHNEY is wireless-only with no headphone jack. The AIAUXAI Over Ear Earbuds is the safer pick for Chromebooks, older iPads, Kindles and MP3 players, since it connects through a standard 3.5mm jack.
The spec sheet rates the 200mAh battery at up to 22 hours of music playback, 20 hours of talk time and 550 hours of standby, with a 2-hour charge. Battery level can be checked on your connected device.
That depends on what you need, not on a number. If you want charging-free simplicity and own a jack-equipped device, the AIAUXAI gives you that with no battery to maintain. If you want wireless freedom, long battery life and dual-device switching, the CALOETHNEY delivers more features. Check the current price on Amazon for each before deciding.
