• Amazon Renewed Powerbeats3 — biggest strength: true wireless freedom with up to 12 hours of playback, Fast Fuel quick-charging, and a secure earhook fit built for movement.
• Amazon Renewed Powerbeats3 — biggest trade-off: it's a Renewed unit, it charges over Micro USB (not USB-C), and it has no active noise cancellation.
• ASKUBSKU USB C — biggest strength: plug-and-play USB-C audio with a built-in DAC, sound isolation, and a wired connection that never needs a battery.
• ASKUBSKU USB C — biggest trade-off: you're tethered to your device by a cable, and the hook-style fit leans sporty rather than discreet.
• Pick the Powerbeats3 if you want wireless convenience for workouts and don't mind a Renewed device.
• Pick the ASKUBSKU USB C if your phone or laptop has dropped the headphone jack and you want reliable wired sound with no charging routine.
The Powerbeats3 is a wireless in-ear sport headphone that connects over Class 1 Bluetooth — and that "Class 1" detail matters more than it sounds. It's rated for a Bluetooth range up to 100 meters, which is far beyond what most everyday earbuds advertise. In practice that means you can leave your phone on a bench, rack, or desk and keep listening as you move around a gym floor or a room without the signal dropping. For a workout headphone, that freedom is the whole point.
Battery is the other headline. The spec sheet lists up to 12 hours of average battery life, and Fast Fuel gives you about 1 hour of playback from a 5-minute charge. If you're the kind of person who grabs your bag and realizes you forgot to charge last night, that five-minute top-up is genuinely useful — enough to get through a commute or a short session. The earhooks are flexible and designed for a secure fit, and the package includes four sets of eartips plus a carrying case and cable, so you can dial in the seal. There's also sweat and water resistance, which is exactly what you'd want from something marketed as a training partner.
It's not perfect, and I'd rather be straight about that. There's no noise cancellation here — the noise control field is listed as "None" — so you'll rely on the in-ear seal to block out gym clatter. It's also a Renewed product, which means it's been inspected and restored rather than sold brand new, and it carries a 90-day limited warranty. And the charging is Micro USB, so if your drawer is full of USB-C cables, you'll want to keep the included one handy. Who should buy it? Anyone who trains hard, wants wireless freedom, and values long battery life over the latest charging standard. Who should skip it? Anyone who wants active noise cancellation, USB-C charging, or a brand-new-in-box product.
The ASKUBSKU USB C earphones solve a very specific, very modern problem: your device no longer has a headphone jack. This is a wired USB-C headphone, which means there's no battery to charge and no Bluetooth pairing to fiddle with. You plug it in and it works — immediately, every time. The spec sheet lists a built-in DAC chip, which is the part that actually converts digital audio to sound, and it's what lets a simple wired earbud deliver clean, high-resolution audio with deep bass and clear treble rather than a thin, tinny signal.
The fit is sport-oriented. The earpieces are hook-shaped and designed to wrap around the ear, and the listing describes them as staying put during running, jogging, and gym work. It's a design choice aimed at one thing: not falling out mid-sprint. The in-ear build also isolates you from ambient noise — the noise control field reads "Sound Isolation," not active cancellation — and you get three sizes of eartips to get a proper seal, which is what actually makes that isolation work.
Compatibility is where this thing really flexes. The compatibility list is enormous: iPhone 17 down through 15, a long run of Samsung Galaxy S and Z series phones, iPads, several MacBook sizes, and Google Pixel models. That breadth is the selling point — if you've got a USB-C port, there's a good chance this fits it. Controls are simple button-based, and the earpiece shape is a hook rather than a flat bud. What's the catch? You're wired, so you can't wander from your device, and the white plastic hook design is more functional than fashionable. Buy it if you want fuss-free wired audio for a phone or laptop that skipped the headphone jack. Skip it if you need wireless freedom or active noise cancellation.
Side-by-Side: Which Should You Choose?
• Best for long battery life → Amazon Renewed Powerbeats3. Up to 12 hours per charge, plus a 5-minute Fast Fuel top-up for 1 hour of playback.
• Best for zero-maintenance audio → ASKUBSKU USB C. No battery, no pairing — plug in and go.
• Best for modern phones without a headphone jack → ASKUBSKU USB C. The USB-C connection covers a huge range of iPhone, Samsung, Pixel, iPad, and MacBook models.
• Best for isolation from gym or street noise → ASKUBSKU USB C. Built-in sound isolation plus three eartip sizes for a tight seal.
• Best for Apple ecosystem conveniences → Amazon Renewed Powerbeats3. It can connect to Apple Watch, iPad and Mac simultaneously (given the right OS and iCloud setup), and RemoteTalk handles calls, music and Siri.
• Best if you want a brand-new product → ASKUBSKU USB C. The Powerbeats3 is a Renewed unit with a 90-day limited warranty.
• Best if you hate charging cables → ASKUBSKU USB C. It draws power from your device, so there's nothing to remember to top up.
If I had to pick one, I'd go with the ASKUBSKU USB C Headphones for most people today. In my opinion, the plug-and-play simplicity wins: no charging, no pairing, no battery anxiety, and it works with the vast majority of current phones and laptops. The built-in DAC and sound-isolating hook fit make it a sensible daily driver for commutes, calls, and workouts where you're near your device.
That said, I'd recommend the Amazon Renewed Powerbeats3 without hesitation for one clear type of buyer: someone who trains hard, wants to move freely, and values marathon battery life over the newest charging standard. If wireless freedom and 12 hours of playback matter more to you than a cable, the Powerbeats3 is the better call. Either way, check the latest price on Amazon before you commit — the button on this page will take you there.
It's wireless. It connects over Class 1 Bluetooth with a rated range up to 100 meters, and it includes a Micro USB cable for charging — not for listening.
No. They're wired and draw power from your device through the USB-C connector, so there's no battery to charge and no Bluetooth pairing to set up.
Both are built for movement. The Powerbeats3 uses flexible earhooks with four eartip sizes for a secure wireless fit, while the ASKUBSKU uses a wrap-around hook design with three eartip sizes and a wired connection. If you want no cable at all, go Powerbeats3; if you want zero charging, go ASKUBSKU.
No. The Powerbeats3 lists noise control as "None," and the ASKUBSKU lists "Sound Isolation," which means it blocks noise passively through the in-ear seal rather than with active cancellation.
If your phone has a USB-C port, very likely yes. The compatibility list covers iPhone 15 through 17, a wide range of Samsung Galaxy and Z series models, Google Pixel, iPads, and several MacBook sizes.
