How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a bulk classroom-ready set of wired earbuds that can equip a whole group at once, choose Yoley Bulk Earbuds Headphones; if you need fully wireless earbuds with a charging case, touch controls and long playtime for one person on the move, choose Aoslen Earbuds.
• Yoley biggest strength: a 100-pack of individually wrapped wired earbuds in five mixed colors — practical for schools, classrooms and groups, not one person.
• Yoley biggest trade-off: wired only, no mic, no Bluetooth — you're tethered to a 3.5 mm jack and get no wireless freedom at all.
• Aoslen biggest strength: fully wireless earbuds with Bluetooth 5.3, 4 ENC mics, an LED battery display and up to 42 hours of total playback with the case.
• Aoslen biggest trade-off: it's a single pair of earbuds for one listener, so it can't outfit a class or a group.
• Who Yoley is for: teachers, schools, parents and organizers who need a lot of cheap, simple, tangle-resistant wired earbuds in one order.
• Who Aoslen is for: one person who wants true wireless earbuds for commuting, workouts and everyday listening.
Yoley Bulk Earbuds Headphones is not really a "pick one pair" product at all — it's a 100-pack. Each pair comes individually packed and wrapped, in five mixed colors: blue, green, pink, black and white. In my opinion that's the whole point here. If you're handing out earbuds to a classroom of students, a group of kids, or a club, having each pair separately wrapped means you're not untangling a bin of loose cables before every session. You grab one, hand it over, done.
The cable itself is about 43 inches (roughly 1.1 m) and uses a thicker wire with a middle knot, which the spec sheet describes as firm and less prone to breaking — a sensible detail for something kids will yank around. The jack is a standard 3.5 mm aux connector, so it works with most smartphones, computers, MacBooks, Chromebooks, laptops, PCs and Android tablets. There's no microphone, so these are for listening, not calling. The rounded-tip in-ear design, plastic enclosure and 32-ohm impedance with a 20 Hz–20 kHz frequency range cover the basics of everyday audio for lessons, videos and casual music.
Who should buy it: teachers building a class set, schools and programs that need to replace lost or broken earbuds in bulk, and parents who want a stack of simple wired earbuds on hand. Yoley also backs it with a 1-year warranty and customer support.
Aoslen Earbuds: Who It's For
Aoslen Earbuds is the opposite kind of purchase: one pair of fully wireless earbuds for one person. The design is in-ear with a dark blue plastic body, and it ships with three sizes of ear tips (S/M/L) so you can dial in the fit. That fit matters, because these are pitched at sport and everyday use — running, training, commuting — and the spec sheet lists IP waterproofing that handles splashes, sweat and light rain.
On the tech side, Aoslen uses Bluetooth 5.3 with a stable connection range of up to 15 meters, which means you can leave your phone on a desk or a bench and keep listening. The audio side runs a 13 mm dynamic driver with a 20 Hz–20,000 Hz range, and there are four ENC microphones for calls — the spec sheet claims a 75% vocal improvement and 50% more bass than a basic setup. That's a manufacturer figure, but the direction is clear: this is built for both music and phone calls in noisy places.
The battery story is the standout. Aoslen rates the earbuds at 6–7 hours of music per charge, with the charging case adding up to 42 hours of total playback. The case charges over USB-C and takes about 1.5 hours to fully charge. There's also a separate LED display that shows the charge level of each earbud and the case, so you're not guessing. Pairing is automatic when you open the case, and touch sensors handle play/pause, calls, volume, track skipping and voice assistant.
Who should buy it: one person who wants true wireless earbuds for workouts, travel and daily listening, and who values playtime and a visible battery readout. Who should skip it: anyone buying for a group, a classroom or a family of kids — one pair doesn't stretch, and there's no wired fallback if the battery runs out.
• Best for classrooms and groups → Yoley Bulk Earbuds Headphones. A 100-pack with individually wrapped pairs simply isn't something a single wireless pair can match.
• Best for true wireless freedom → Aoslen Earbuds. Bluetooth 5.3 with up to 15 m range and no cable at all.
• Best for battery life → Aoslen Earbuds. Up to 42 hours total with the case, plus a 1.5-hour case recharge over USB-C.
• Best for long listening sessions without charging → Aoslen Earbuds. 6–7 hours per earbud charge is well beyond a typical wired session you'd have to plug in for.
• Best for calls and voice → Aoslen Earbuds. Four ENC microphones versus Yoley's no-mic wired design.
• Best for the widest device compatibility with zero setup → Yoley Bulk Earbuds Headphones. A plain 3.5 mm jack works with almost anything, no pairing, no charging.
• Best for kids and shared equipment → Yoley Bulk Earbuds Headphones. Individually wrapped pairs, tougher cable, five colors, 1-year warranty.
• Best for sport and sweat → Aoslen Earbuds. In-ear fit with three tip sizes and splash/sweat-resistant waterproofing.
If I had to buy one for myself, I'd choose Aoslen Earbuds. In my opinion, for a single person who wants music, calls and no cable, the combination of Bluetooth 5.3, four ENC mics, a visible battery display and up to 42 hours of total playtime is the more useful package — and the three ear-tip sizes make a real difference for comfort and workout stability. I'd only go with Yoley if my goal were outfitting a group, because a 100-pack of individually wrapped wired earbuds solves a completely different problem. So: for personal wireless listening, Aoslen; for bulk classroom supply, Yoley.
how long do wireless earbuds last
It depends on the model, but Aoslen rates its earbuds at 6–7 hours of music per charge, with the charging case extending total playback to up to 42 hours. Yoley's wired earbuds don't use a battery at all, so runtime isn't a factor — they run as long as your device does.
how long does it take to fully charge wireless earbuds
The Aoslen charging case takes about 1.5 hours to fully charge using the included USB-C cable. The earbuds themselves charge inside the case, so keeping the case topped up is what keeps the earbuds ready.
how do i know if my wireless earbuds are fully charged
Aoslen uses a separate LED display that shows the charge level of each earbud and the charging case, so you can read the status directly instead of guessing. With Yoley's wired earbuds there's nothing to charge — they draw power from whatever device they're plugged into.
how long do wireless earbuds last
Two things are worth separating: how long a single charge lasts, and how long the product stays useful. Aoslen gives 6–7 hours per charge and up to 42 hours with the case, and its plastic in-ear build is designed for everyday sport and commuting use. Yoley's wired pairs are built around a thicker, knotted cable and a 1-year warranty for classroom wear and tear.
