If you want a USB-C earphone with a long manufacturer warranty and simple button controls for calls, choose LUDOS Zenith USB C; if you need lively pop-tuned sound with four sizes of eartips and a Korean moon-jar-inspired design, choose AZLA APL-120C.
• LUDOS Zenith USB C — biggest strength: a 5-year warranty and a touch/button control mix for call control, plus a 32 ohm impedance that's easy to drive from a phone's USB-C port.
• LUDOS Zenith USB C — biggest trade-off: its noise control is listed as sound isolation rather than active noise cancellation, so it mostly blocks outside noise passively by sealing your ear.
• AZLA APL-120C — biggest strength: an 8mm dynamic driver tuned for K-POP and modern pop, with clear vocals and treble, and four sizes of eartips included for a secure fit.
• AZLA APL-120C — biggest trade-off: noise control is listed as none, and the warranty is listed as n.a., so there's no long coverage to lean on.
• Who each pick is for: LUDOS Zenith USB C suits buyers who want a long warranty and straightforward controls; AZLA APL-120C suits listeners who care most about a lively, vocal-forward tuning and fit options.
The LUDOS Zenith USB C is a wired in-ear earphone that connects over USB Type C, which means it plugs straight into modern iPhone, iPad, Samsung Galaxy and other USB-C devices without a dongle or adapter. It's built around a thermoplastic elastomer (TPE) enclosure in brown, an in-ear fit, and a 32 ohm impedance with a 20Hz–20,000Hz frequency range — the kind of load most phones and tablets drive easily. Controls are handled by a combination of touch and button input focused on call control, so you can manage phone calls without pulling the phone out of your pocket.
What it does best is feel like a low-fuss daily pair. It's wired, so there's no charging to remember, no pairing, no battery anxiety. It ships as a single item with the cable and the ZENITH earphones included. That combination — wired USB-C, call control, easy impedance — is exactly what you want if you take a lot of calls on a laptop or phone and don't want to think about charging a case.
Who should skip it: if you need active noise cancellation, this isn't that — the noise control field is sound isolation, which is passive. And if you want the tuning itself to be the headline feature, the sheet doesn't describe a specific sound signature the way the AZLA does. It's a practical pick, not a flavor-forward one.
AZLA APL-120C: Who It's For
The AZLA APL-120C is a white USB-C wired earbud with a built-in mic, made for iPhone, Samsung and Android devices that have USB-C outlets. Its identity is sound-first: AZLA tuned it to bring out the energy of K-POP and modern pop, with clear vocals and treble, and it uses an 8mm dynamic driver. The listed sensitivity is 104dB SPL/mW at 1kHz and the impedance is 16Ω at 1kHz, which is a low-impedance, easy-to-drive spec — the kind of pairing that gets loud quickly from a phone's own output without needing a separate amp.
The design story is deliberately aesthetic: AZLA says the earbud shape is inspired by the minimal, elegant lines of the Korean moon jar. That's a real differentiator if you care how your earphones look, not just how they measure. It also includes four sizes of eartips, which matters more than people expect — a correct seal is what actually gives you bass and passive isolation, and four sizes gives you a much better shot at that than the usual two or three.
Who should buy it: pop and K-POP listeners who want vocals pushed forward, anyone who has trouble getting a stable fit with standard eartips, and buyers who want an inline controller for calls, music and volume. The built-in mic and inline controls make it a genuine everyday commuter and work-call option, not just a music toy.
Who should skip it: if warranty length is a deciding factor for you, note the warranty description is listed as n.a. — there's no stated coverage to compare against LUDOS. And if you want any kind of noise control, the sheet lists none; you're relying entirely on the eartip seal for isolation.
• Best warranty → LUDOS Zenith USB C. Five years of stated coverage versus none stated for AZLA.
• Best for pop and K-POP tuning → AZLA APL-120C. Purpose-tuned for clear vocals and treble energy.
• Best for fit flexibility → AZLA APL-120C. Four eartip sizes included.
• Best for simple call handling → LUDOS Zenith USB C. Call-control focus with touch and button input.
• Best for easy driveability → AZLA APL-120C. 16Ω at 1kHz is very low impedance, so phones drive it without effort.
• Best for passive isolation → LUDOS Zenith USB C. Sound isolation is listed as a control feature.
• Best for a subtle, understated look → LUDOS Zenith USB C. Brown TPE in-ear build.
• Best for a designed, decorative look → AZLA APL-120C. The moon-jar-inspired shape is a deliberate style statement.
If I were buying for myself, I'd pick the LUDOS Zenith USB C. In my opinion, the five-year warranty plus straightforward call control and a 32 ohm, 20Hz–20,000Hz driver makes it the safer long-term daily pair — especially for someone who uses wired USB-C earphones for calls as much as music. The AZLA APL-120C is the better choice if sound character and fit are what you care about most, because its 8mm dynamic driver is explicitly tuned for pop and K-POP and it ships with four eartip sizes. But for most people who just want one reliable wired USB-C earphone that keeps working, I'd go LUDOS. Check the current price on Amazon before deciding, since that's the one thing that can shift the math.

Same idea as any Android device: plug into the USB-C port and play. The AZLA APL-120C includes a built-in mic and inline controller for calls, music and volume, while the LUDOS Zenith USB C focuses its controls on call control via touch and button input.
how to use usb c headphones on ps5
The PS5 has a USB-C port, so a wired USB-C earphone can connect there. Keep in mind the PS5's USB audio handling and your in-game chat setup determine what works, and neither sheet lists console-specific features — so treat these as general wired USB-C earphones rather than gaming headsets.
