If you want a budget wired earbud that plugs into almost anything with a headphone jack and gives you a snug, customizable in-ear fit, choose Panasonic ErgoFit; if you need a USB-C connection, in-line volume control, and a set of switchable sound and voice modes, choose Jelanry USB C Headphones.
• Panasonic ErgoFit — biggest strength: a true 3.5 mm jack plus three earpad sizes (S/M/L), so it fits a huge range of devices and a huge range of ears.
• Panasonic ErgoFit — biggest trade-off: it is a wired analog bud with no volume buttons and no digital processing — just a mic and a call controller.
• Jelanry USB C Headphones — biggest strength: USB-C digital audio with a Hi-Res/DAC decoder chip, plus adjustable music modes and voice-change modes you won't find on a basic bud.
• Jelanry USB C Headphones — biggest trade-off: it only works with USB-C ports, and its own compatibility notes explicitly exclude older iPhones and any device without a Type-C jack.
• Pick Panasonic ErgoFit if you want maximum device compatibility and a fit you can fine-tune with three tip sizes.
• Pick Jelanry USB C Headphones if your phone, tablet or laptop has dropped the headphone jack and you want on-cable volume control and sound tweaking.
The ErgoFit is the definition of a "just works" earbud. It terminates in a standard 3.5 mm jack, so it slots into phones, laptops, tablets and anything else with a headphone port. There's no pairing, no charging, no app — you plug in and listen. For a lot of people, that's the entire appeal.
The audio side is built around 9 mm neodymium drivers with a listed frequency response up to 24 kHz, 16 ohm impedance, 200 mW maximum input power and 96 dB/mW sensitivity. In plain terms: it's easy to drive, so even a weak laptop output will get it loud, and the tuning is described as tonally balanced with crisp highs and deep lows. The 3.6-foot cord is long enough to thread through a jacket or bag without yanking.
The real selling point is the fit system. Panasonic includes small, medium and large elliptical earpads, and the brand is upfront that the wrong tip size hurts both sound quality and call performance — which is honest and, in my experience reading spec sheets like this, usually true of any in-ear bud. The soft, rounded pads are designed to sit securely and ease fatigue over long sessions, and the sound-isolation design helps block ambient noise. An in-line mic and call controller handle calls and basic remote functions, and it's listed as compatible with Apple, Android and BlackBerry devices (with a note that iPhone 7 and later need a Lightning adapter, sold separately).
Buy it if you want a wired bud for calls, podcasts, video meetings and music on a mix of older and newer devices, and you value being able to swap tip sizes. Skip it if your phone has no headphone jack and you don't want to carry an adapter, or if you want volume buttons on the cable — this one only offers call control.
The Jelanry is aimed squarely at the post-headphone-jack world. It's a USB-C earbud, so it's built for modern phones, tablets, laptops and desktops that use Type-C. Inside, it uses a hybrid driver setup with a 20 Hz–40,000 Hz frequency range and 32 ohm impedance, paired with a Hi-Res and DAC digital decoder chip that converts the digital signal and, per the brand, delivers high-fidelity lossless-style audio. That's a genuinely different approach from an analog bud: the decoding happens in the earbud, not in your phone.
What sets it apart is the feature stack. There are five adjustable music modes — Normal, Deep Bass, Voice Enhancement, Clear Voice and Game Mode — so you can push bass for a workout or sharpen voices for a call or podcast. There are also seven voice-change modes (Original Sound, KTV, Concerts, Male Voice, Female Voice, Children Voice), which the brand pitches as a fun extra for chatting. Whether you use them or not, they exist as a real differentiator.
Controls are more complete than the Panasonic's: in-line buttons handle play/pause, track skip, volume and call answer/reject, so you rarely need to touch your phone. The built-in mic supports hands-free calling. The brand positions it for exercise — running, jogging, lifting, walking, hiking — and the black ABS-and-metal housing fits that sporty theme.
Compatibility is broad but specific: iPhone 15/16/17 series, a long list of Samsung Galaxy models, Google Pixel, iPad, MacBook, Surface, OnePlus, Xiaomi and more — all via USB-C. Critically, the brand states it does not fit other iPhone models. Buy it if you're on a USB-C device and want volume control, sound modes and a little novelty on the cable. Skip it if you still rely on a 3.5 mm jack, since there's no analog option here.
• Best for device compatibility → Panasonic ErgoFit. A 3.5 mm jack works with far more gear, including older phones and basic laptops.
• Best for modern phones without a headphone jack → Jelanry USB C Headphones. Native USB-C, no adapter required.
• Best for on-cable volume control → Jelanry USB C Headphones. It has volume buttons; the Panasonic offers call control only.
• Best for fit customization → Panasonic ErgoFit. Three earpad sizes (S/M/L) let you dial in the seal.
• Best for sound tweaking → Jelanry USB C Headphones. Five music modes and seven voice modes versus a single fixed tuning.
• Best for simple, no-fuss listening → Panasonic ErgoFit. No modes, no menus, no chip — just plug and play.
• Best for workouts and sport → Jelanry USB C Headphones. The brand explicitly targets running, jogging and gym use, with a protective case included.
• Best for iPhone 15/16/17 owners → Jelanry USB C Headphones. It's built for those USB-C iPhones; older iPhones need the Panasonic plus an adapter.
If I had to pick one, I'd go with the Panasonic ErgoFit — not because it's fancier, but because it fits more situations. The 3.5 mm jack, three tip sizes, comfortable long-wear design and simple mic-and-call setup make it the safer everyday choice for calls, meetings and music across mixed devices.
That said, if your phone is a USB-C model and you actively want volume buttons plus switchable sound modes, the Jelanry USB C Headphones is the more feature-rich pick and the one I'd recommend for that setup.
